Italian Penicillin Soup Recipe
There are dishes that comfort you, and dishes that surprise you. The Italian Penicillin Soup Recipe is both: it looks and smells like a classic Italian bowl of warmth — savory stock, roasted garlic, pancetta, and Parmesan — but it carries a clever, modern twist: a touch of honey, fresh lemon, and fresh or preserved ginger that lift the flavors and give the soup a bright, healing quality. Think of it as an Italian-style comfort tonic — lots of umami and richness, balanced by bright citrus and sweet-ginger notes. It’s not a medical remedy, of course, but it’s the sort of bowl that feels like one.
Below you’ll find everything you need: precise ingredients for about 6 servings, detailed step-by-step instructions, technique tips, variations (vegetarian, vegan, gluten-free), make-ahead and storage advice, serving ideas, and pairing suggestions. I’ve written this as a professional chef who wants you to both learn and enjoy the process — so pull out your largest saucepan and let’s make something memorable.
What makes this the “Italian Penicillin Soup”?
The name borrows two inspirations. First, the classic penicillin cocktail (whisky + ginger + honey + lemon) is known as a reparative, warming drink — the soup borrows the ginger-honey-lemon trio for a bright, restorative finish. Second, the base is unmistakably Italian: pancetta, soffritto (onion, celery, carrot), Parmesan rind, and a long-simmered stock. The result is a balanced fusion: rich and savory, with bright, soothing elements that cut through the fat and lift each spoonful.
This is why the Italian Penicillin Soup Recipe works so well: umami, fat, acid, and sweetness — all present and balanced.

Ingredients (serves 5–6)
Base & proteins
- 4 tablespoons extra-virgin olive oil (divided)
- 4 oz (115 g) pancetta or thick-cut bacon, diced (optional for vegetarian)
- 1 large yellow onion, finely diced (about 1 ½ cups)
- 2 medium carrots, peeled and diced (about 1 cup)
- 2 celery stalks, diced (about 1 cup)
- 6 cloves garlic — 4 minced + 2 whole cloves, unpeeled (for roasting)
- 1–2 teaspoons freshly grated ginger (start with 1 tsp — adjust to taste)
- 1 cup dry white wine (optional — Soave/Pinot Grigio), or extra stock
Stock & foundations
- 8 cups good-quality chicken stock or low-sodium chicken broth (homemade preferred)
- 1 Parmesan rind (or 3 tablespoons grated Parmesan if rind not available)
- 1 bay leaf
- 1 sprig fresh rosemary (or ½ tsp dried)
- 1 tablespoon tomato paste (adds depth)
- 1 cup cooked shredded chicken (rotisserie works great) — optional for a meatier soup
Finishing & flavor lift
- 2 tablespoons honey (adjust to taste)
- Juice of 1 large lemon (about 2–3 tablespoons) + extra lemon wedges to serve
- Salt and freshly ground black pepper, to taste
- 2 tablespoons chopped fresh parsley (for garnish)
- Zest of ½ lemon (optional, for bright aroma)
- 2 tablespoons extra-virgin olive oil (to finish)
- Optional: 1–2 teaspoons good-quality smoky Scotch or aged whisky (drizzle per bowl; optional — for adult diners only)
To serve
- Crusty bread or garlic-toasted slices
- Shaved Parmesan or Pecorino
- Toasted breadcrumbs or crostini
- Extra chili flakes or chili oil (if you like heat)
Equipment & mise en place
- Large heavy-bottomed pot or Dutch oven (6–8 quart)
- Sheet pan (for roasting garlic)
- Microplane/zester, chef’s knife, cutting board
- Ladle and fine-mesh sieve (if you want a silky broth)
- Small bowl to mix honey + lemon (makes incorporation easier)
Mise en place: dice the soffritto (onion, carrot, celery), mince the garlic, grate the ginger, shred the chicken, and have your stock and Parmesan rind ready. Pre-measuring keeps the flow smooth.
Step-by-step preparation
Below I’ll give a clear, professional sequence — followed by options for shortcuts and variations.
1) Roast the garlic (flavor-building step)
Preheat the oven to 400°F (200°C). Place the two whole unpeeled garlic cloves on a small sheet of foil or a baking tray, drizzle with a little olive oil, and roast for 18–22 minutes until soft and lightly caramelized. Roasted garlic brings a mellow, slightly sweet depth that contrasts beautifully with the bright lemon and ginger at the finish.
Tip: If you don’t want to roast garlic, gently sauté the minced garlic in step 2, but roasting adds a deeper, more rounded flavor.
2) Render the pancetta and build the soffritto
Heat 2 tablespoons of olive oil in your Dutch oven over medium heat. Add the diced pancetta and cook until the fat renders and the pancetta is golden and slightly crisp (5–8 minutes). If you’re making a vegetarian version, skip pancetta and use an extra tablespoon of oil and a pinch of smoked paprika for savory depth.
Add the diced onion, carrots, and celery. Sauté the soffritto, stirring often, until the onions are translucent and the vegetables soften — about 8–10 minutes. This slow sweat is critical: it develops sweetness and the foundational flavor.
3) Add garlic, ginger, and tomato paste
Stir in the minced garlic and freshly grated ginger. Cook 1–2 minutes until fragrant (careful not to burn). Add the tomato paste and cook it for 1–2 minutes, stirring — this caramelizes the paste and deepens the base.
Tip: Fresh ginger provides a bright, clean zing; you can use finely minced preserved ginger or ½ tsp ground ginger in a pinch, but fresh is best.
4) Deglaze and simmer
Pour in the white wine and scrape any brown bits from the bottom of the pot. Let it reduce for 2–3 minutes until mostly evaporated. Add the chicken stock, Parmesan rind, bay leaf, and rosemary. Bring the pot to a gentle simmer, then lower the heat to maintain a gentle, steady simmer for 25–30 minutes to marry the flavors.
If you’re using shredded chicken, add it for the last 10 minutes to heat through.
5) Finish with honey and lemon — the “penicillin” twist
Remove the Parmesan rind and the rosemary sprig and discard. In a small bowl, whisk together the honey and lemon juice so the honey emulsifies and integrates easily; this prevents the honey from clumping. Gradually stir the honey-lemon into the soup and taste. Adjust: add more lemon for brightness, more honey for sweetness, or more grated ginger for bite.
Season with salt and pepper to taste. Because Parmesan rind and pancetta can be salty, always taste before final salting.
6) Optional step: blend for silkiness
For a silky, uniform texture, remove 2–3 cups of the soup (or an immersion blender-safe amount) and puree until smooth, then stir back into the pot. Alternatively, use an immersion blender for a few pulses — leave some texture by not fully pureeing. If you prefer a chunkier, more rustic soup, skip blending entirely.
7) Plate and finish
Ladle into warmed bowls. Finish each bowl with a drizzle of good olive oil, a sprinkle of freshly chopped parsley, lemon zest, and shaved Parmesan. For adventurous adult diners, add a tiny drizzle (¼–½ teaspoon) of smoky Scotch or aged whisky on the surface — this emulates the smoky-sweet note of the penicillin cocktail without overpowering the soup. Serve with crusty bread, grilled cheese, or toasted crostini.
Detailed timing & temperature checklist
- Roasting garlic: 18–22 minutes at 400°F (200°C)
- Rendering pancetta: 5–8 minutes, medium heat
- Sweating soffritto: 8–10 minutes, medium-low heat
- Simmering soup: 25–30 minutes, gentle simmer
- Total active time: ~40–50 minutes (plus roasting garlic)
- Total time: ~1 hour (including resting and optional blending)
Chef’s tips & technique notes
- Start with good stock. The backbone of any great soup is the stock. Homemade chicken stock will give you superior body and flavor. If using store-bought, choose a high-quality low-sodium option so you can control salt.
- Parmesan rind = flavor gold. Tossing a rind into the simmering pot adds a rich, savory depth. Remove before serving.
- Balance is everything. The honey and lemon should be in balance: honey softens the lemon edge and amplifies mouthfeel; lemon brightens and cuts through fat. Add gradually and taste as you go.
- Ginger restraint. Fresh ginger can dominate; start with 1 tsp and add more in small increments.
- Salt last. Because pancetta and Parmesan contribute salt, finish seasoning at the end.
- Texture control. Blending some of the soup gives a creamy mouthfeel without heavy cream. If you prefer creamier, you can stir in ¼–½ cup heavy cream at the end (or a splash of crème fraîche) — but try it without first.
- Alcohol notes. If using wine, let it reduce to cook off most alcohol and concentrate flavor. If you add whisky at the end, it’s a flavor accent — not a booze bomb — so less is more.
- Heat control. Keep the main simmer low and steady. Rapid boiling will cloud the stock and can toughen chicken.
Variations (so you can adapt this recipe)
Vegetarian Italian Penicillin Soup (no pancetta, hearty)
- Omit pancetta. Use 3 tablespoons olive oil with 1 teaspoon smoked paprika and 1 teaspoon soy sauce or tamari for savory depth.
- Swap chicken stock for vegetable stock and add 1 cup sliced cremini mushrooms, sautéed until golden.
- Use grated vegetarian Parmesan (or nutritional yeast + miso for depth).
- Add cooked white beans (cannellini) for protein and heartiness.
Vegan version
- Use robust vegetable stock, sautéed mushrooms, and 2 tablespoons miso paste (dissolved in a little warm water) instead of Parmesan rind.
- Replace honey with maple syrup or agave.
- Use vegan Parmesan or blend 2 tablespoons of toasted cashews with nutritional yeast for a cheesy finish.
Gluten-free & dairy-free
- This recipe is naturally gluten-free if you avoid breadcrumbs and use gluten-free bread for serving.
- For dairy-free, omit Parmesan and use a few tablespoons of nutritional yeast and a Parmesan-like seasoning (or a piece of kombu to add umami).
Hearty pasta or orzo version
- Add ¾ cup dried orzo or small pasta to the simmering pot for the last 10 minutes, or serve the soup over cooked orzo for a more substantial meal.
- When adding pasta, reduce final simmer time by what the pasta package recommends to avoid mush.
Make-ahead, storage & reheating
- Make-ahead: The soup tastes even better the next day. Cool completely, then refrigerate in airtight containers for up to 4 days.
- Freezing: This soup freezes well (without dairy finishes). Freeze in portioned freezer-safe containers for up to 3 months. Thaw overnight in fridge before reheating.
- Reheating: Gently rewarm over low to medium heat — avoid boiling to preserve texture. If the soup thickened in the fridge, add a splash of stock or water while reheating.
- Leftover ideas: Turn it into a sauce for roasted vegetables, use as a saucy base for a quick risotto, or ladle over grilled fish.
Allergen notes & substitutions
- Dairy: Parmesan contains dairy; omit or use alternatives for dairy-free.
- Gluten: Use gluten-free pasta/bread if needed.
- Alcohol: Wine and Scotch are optional; omit for a non-alcoholic dish.
- Pork: Replace pancetta with smoked mushrooms or tempeh bacon for a vegetarian option.
Serving suggestions & pairings
Bread & toppings
- Serve with rustic country bread or garlic crostini to mop up the broth.
- For crunch, top with toasted breadcrumbs tossed with olive oil, garlic, and parsley.
- Finish bowls with shaved Parmesan, lemon zest, and a drizzle of extra-virgin olive oil.
Salads
- A crisp little salad of arugula, shaved fennel, and lemon vinaigrette keeps the meal bright.
- Simple Caesar or a herb salad pairs nicely.
Wine pairings
- White: an Italian white like Vermentino or Soave complements the soup’s brightness.
- Light red: a chilled Chianti Classico or Barbera with moderate acidity goes well if you include pancetta and shredded chicken.
- Non-alcoholic: sparkling water with lemon or a bright herbal tea (e.g., lemon verbena).
Entrée ideas
- Pair with a simple grilled chicken breast or pan-seared fish for a heartier dinner.
- Serve as a first course for a multi-course Italian meal — for main, go with roasted short ribs or mushroom risotto.
Common troubleshooting
- Soup tastes flat: Likely needs acid and salt. Add a squeeze of lemon and salt in small increments. A dash of vinegar (white wine or sherry) can also wake it up.
- Too salty: Add peeled, diced potato and simmer 10 minutes (remove potato before serving) or dilute with unsalted stock/water and rebalance with acid.
- Too sweet from honey: Add more lemon juice or a teaspoon of white wine vinegar to balance.
- Broth looks cloudy: Keep tomato paste well-caramelized and maintain a gentle simmer; rapid boiling and stirring can cloud it.
Health & nutrition note
This recipe balances rich umami from pancetta and Parmesan with bright lemon and ginger for a satisfying bowl. It’s comforting and nourishing but not a substitute for medical care. If you’re cooking for people with dietary restrictions, follow the substitutions listed above.

- 2 tablespoons chopped fresh parsley for garnish
- Zest of ½ lemon optional
- 2 tablespoons extra-virgin olive oil to finish
- Optional: shaved Parmesan or Pecorino toasted breadcrumbs, chili flakes, or a tiny drizzle of smoky Scotch for adult bowls
Instructions
- Preheat & roast garlic — Preheat oven to 400°F (200°C). Place the two whole unpeeled garlic cloves on a small sheet of foil or a baking tray, drizzle with a little olive oil, and roast 18–22 minutes until soft and caramelized. Set aside.
- Render pancetta — In a large Dutch oven or heavy pot, heat 2 tablespoons olive oil over medium heat. Add diced pancetta and sauté until fat renders and pieces are golden-crisp, about 5–8 minutes. (For vegetarian: skip pancetta and use an extra tablespoon olive oil + 1 tsp smoked paprika.)
- Build the soffritto — Add diced onion, carrots and celery to the pancetta. Reduce heat to medium-low and sweat the vegetables, stirring occasionally, until softened and translucent, about 8–10 minutes.
- Add aromatics — Stir in the minced garlic (reserve roasted garlic) and grated ginger; cook 1–2 minutes until fragrant. Mix in the tomato paste and cook 1–2 minutes, stirring to caramelize the paste slightly.
- Deglaze — Pour in the white wine and scrape up any browned bits from the pot bottom. Let the wine reduce for 2–3 minutes until mostly evaporated.
- Simmer the soup — Add chicken stock, Parmesan rind, bay leaf, and rosemary. Bring to a gentle simmer, then reduce heat to low and simmer uncovered for 25–30 minutes. Add shredded chicken during the last 10 minutes to heat through (if using).
- Finish with the “penicillin” touch — Remove and discard the Parmesan rind and rosemary sprig. Mash the roasted garlic into a paste and add to the pot. In a small bowl, whisk together honey and lemon juice; stir into the soup gradually and taste. Adjust honey, lemon, and grated ginger to balance sweetness and brightness. Season with salt and pepper.
- Optional texture control — For a silkier mouthfeel, remove 2–3 cups of the soup and puree until smooth, then stir back in. Or pulse briefly with an immersion blender, leaving some texture.
- Plate & garnish — Ladle into warmed bowls. Finish each bowl with a drizzle of extra-virgin olive oil, lemon zest, chopped parsley, and shaved Parmesan or toasted breadcrumbs if desired. Serve with crusty bread or crostini.
Notes
- Taste for salt last: pancetta and Parmesan add saltiness, so salt near the end.
- Roasted garlic vs. raw: roasting mellows garlic and adds depth — use it if you have time.
- Ginger: fresh ginger provides lift — add in small increments to avoid overwhelming the bowl.
- Vegetarian variation: omit pancetta and chicken; use vegetable stock, sautéed mushrooms, 1 tsp smoked paprika, and 2 tbsp miso or soy sauce for umami; use vegetarian Parmesan or nutritional yeast.
- Vegan swap: use vegetable stock, maple syrup for honey, miso for savory depth, and blend toasted cashews + nutritional yeast for creaminess.
- Make-ahead: soup often tastes better the next day — refrigerate up to 4 days in airtight containers. Reheat gently over low heat.
- Freezing: cool and freeze (without dairy finishes) for up to 3 months. Thaw overnight in fridge and reheat gently, adding a splash of stock if needed.
- To thicken: add ¾ cup orzo or small pasta for the last 8–10 minutes, or blend part of the soup for creaminess.
- Troubleshooting: if too salty, dilute with unsalted stock and rebalance with lemon; if too sweet, add a touch more lemon or vinegar.
