Ingredients

(Serves 4)

Pasta
- 12 oz (340 g) dried fettuccine or pappardelle

Mushrooms & Aromatics
- 12 oz (340 g) oyster mushrooms, cleaned and torn into bite-size pieces
- 1 medium yellow onion, finely diced
- 3 cloves garlic, minced

Cream Sauce Base
- 1 ½ cups (360 ml) heavy cream (or full-fat coconut milk for dairy-free)
- ½ cup (120 ml) vegetable or chicken broth
- 3 Tbsp unsalted butter (or vegan butter)
- 1 Tbsp all-purpose flour (optional, for extra thickness)

Cheese (Optional)
- ½ cup freshly grated Parmesan or Pecorino Romano
Herbs & Seasonings
- 1 Tbsp fresh thyme leaves, minced (or 1 tsp dried thyme)
- 2 Tbsp fresh flat-leaf parsley, chopped (for garnish)
- Salt and freshly ground black pepper, to taste
- Pinch of red pepper flakes (optional, for heat)

Finishing Touches
- Zest of ½ lemon
- 1 Tbsp extra-virgin olive oil

Equipment

Large pot for boiling pasta
Large sauté pan or skillet with a tight-fitting lid

Fine mesh strainer or colander

Wooden spoon or heat-proof spatula
Microplane or fine grater (for zest)

Chef’s knife and cutting board

Prep Work

Clean and Tear Mushrooms
- Gently wipe oyster mushrooms with a damp paper towel. Avoid rinsing under water, as they’ll absorb moisture. Tear into uniform, bite-size clusters so they cook evenly.

Dice the Onion & Mince Garlic
- Finely dice the onion to ensure it melts into the sauce. Mince garlic to release its aroma without large chunks.
Grate Cheese and Zest Lemon
- If using cheese, grate it fresh—pre-grated lacks the silky mouthfeel. Zest the lemon before juicing, then set aside.

Pro Tip: Reserve ½ cup of starchy pasta water before draining. It helps bind and loosen the sauce later, if needed.

Cooking Steps

1. Cook the Pasta Al Dente

Bring a large pot of well-salted water to a rolling boil.
Add pasta and cook per package instructions, usually 8–10 minutes.

Stir occasionally to prevent sticking.

When pasta is just shy of al dente (firm to the bite), scoop out ½ cup of pasta water, then drain pasta and set aside.

2. Sauté the Mushrooms

In a cold skillet, add 1 Tbsp butter and 1 Tbsp olive oil over medium-high heat.

Once shimmering, add oyster mushrooms in a single layer. Let them sear undisturbed for 2–3 minutes so they brown and concentrate their flavor.

Stir and continue cooking until lightly golden and tender, another 2 minutes. Transfer mushrooms to a plate.

3. Build the Flavor Base

Reduce heat to medium. In the same skillet, add remaining 2 Tbsp butter.

Add diced onion; sauté until translucent, about 3–4 minutes.

Stir in garlic and cook 30 seconds until fragrant.
Optional: Sprinkle flour over aromatics, stir to coat, and cook 1 minute to remove raw flour taste.

4. Create the Cream Sauce

Gradually whisk in broth, scraping up any browned bits (fond) from the pan.

Pour in heavy cream, bring to a gentle simmer—don’t boil vigorously or the cream may separate.
Season with thyme, salt, pepper, and a pinch of red pepper flakes.

Simmer sauce until it thickens slightly, about 4–5 minutes.

5. Bring It All Together

Return sautéed oyster mushrooms to the pan.
Add drained pasta and toss to coat. If the sauce feels too thick, stir in a splash of reserved pasta water until it clings to the noodles.

Off heat, stir in grated cheese and lemon zest for brightness.

Chef’s Insight: Finishing off-heat prevents the sauce from over-thickening and keeps the cheese creamy rather than stringy.

Chef’s Tips for Perfection

Choose Fresh Oyster Mushrooms
- Look for firm, unblemished clusters. Avoid slimy or overly moist mushrooms.

Mind Your Heat
- Sear mushrooms on higher heat for color, then lower to medium for aromatics and sauce.
Pasta Water Is Liquid Gold
- The starch in the water helps bind the sauce to the pasta—reserve some even if you think you won’t use it.

Avoid Over-Salting
- Taste your sauce before adding salt; the Parmesan and pasta water may already contribute enough sodium.

Don’t Rush the Simmer
- Gentle simmering ensures the sauce thickens without breaking. Rapid boiling can cause separation.

Variations and Customizations

Vegan Twist
- Swap heavy cream for full-fat coconut milk or a blend of cashew cream and nondairy milk. Use vegan butter and nutritional yeast instead of cheese.

Protein Boost
- Add pan-seared chicken breast strips, shrimp, or Italian sausage slices. Sauté them before mushrooms, then follow the recipe.

Mushroom Medley
- Mix oyster mushrooms with cremini, shiitake, or porcini for a more complex umami profile.
Herb-Forward
- Stir in fresh basil or tarragon at the end for a vibrant twist.

Spicy Kick
- Infuse red pepper flakes in the oil at the start, or finish with a drizzle of chili-infused olive oil.

Serving Suggestions & Pairings

Garnishes
- Extra parsley, a sprinkle of flaky sea salt, or microgreens for color and freshness.
Bread on the Side
- Crusty ciabatta, garlic bread, or focaccia for sopping up every last drop of sauce.

Salad Accompaniment
- A crisp arugula salad with lemon vinaigrette balances the richness.

Wine Pairing
- White: A lightly oaked Chardonnay or Viognier complements the creaminess.
- Red: A light Pinot Noir brings out the earthiness of mushrooms without overpowering the sauce.

Non-Alcoholic
- Sparkling water with a squeeze of lemon; ginger kombucha adds a zesty contrast.

Storage & Make-Ahead

Refrigeration: Store leftovers in an airtight container for up to 3 days. Gently reheat over low heat, stirring in a splash of cream or pasta water to revive the sauce.

Freezing: Not recommended—the cream sauce can separate and turn grainy upon thawing.

Make-Ahead: You can prepare the mushroom-cream base a day ahead (without cheese), refrigerate, then reheat and stir in cheese just before tossing with freshly cooked pasta.

Frequently Asked Questions

Q: Can I use other types of pasta?
A: Absolutely! While fettuccine or pappardelle hold the sauce beautifully, penne, rigatoni, or even orecchiette work well. Adjust cooking times as needed.

Q: How do I prevent the sauce from breaking?
A: Keep your heat moderate, avoid rapid boiling, and finish off heat when adding cheese. If separation occurs, whisk in a small pat of butter to bring it back together.

Q: Is this recipe dairy-free friendly?
A: Yes—use full-fat coconut milk or cashew cream, vegan butter, and omit Parmesan (or replace with nutritional yeast).

Q: My sauce is too thin—how do I thicken it?
A: Simmer a bit longer to reduce, or whisk in a slurry of 1 tsp cornstarch mixed with 1 Tbsp cold water. Add gradually until desired consistency.
