Ingredients

For the Main Dish:

• 12 oz dry pasta (fettuccine, linguine, or penne)
• 1 tbsp olive oil
• 2 tbsp unsalted butter
• 12 oz cremini or baby bella mushrooms, sliced (about 4 cups)
• 1 small shallot, finely chopped (or 1/2 small onion)
• 3 cloves garlic, minced
• 5 oz baby spinach (about 5 cups loosely packed)
• 1/2 cup low-sodium chicken or vegetable broth
• 1 cup heavy cream
• 3/4 cup grated Parmesan cheese, plus more for serving
• 1 tbsp fresh lemon juice (about 1/2 lemon)
• 1/4 tsp red pepper flakes (optional)
• Salt and freshly cracked black pepper, to taste
• Fresh parsley, chopped, for garnish

For the Sauce / Garnish (if applicable):

• Extra Parmesan for serving
• Optional lemon zest for brightness

How I Make It

Step 1:

Bring a large pot of salted water to a rolling boil and cook the 12 oz pasta until al dente (usually 8–10 minutes depending on the shape). Reserve 1 cup of the pasta water before draining — that starchy water becomes liquid gold for the sauce. The water should taste mildly salty like seawater.

Step 2:

While the pasta cooks, heat a large skillet over medium-high heat with 1 tbsp olive oil and 2 tbsp butter. When the butter foams and fills the pan with a nutty aroma, add the sliced mushrooms in a single layer. Let them sit and sizzle until the edges turn golden, about 5–6 minutes — don’t stir too much; you want those browned bits for flavor.

Step 3:

Add the chopped shallot and garlic, and sauté for about 1–2 minutes until fragrant — you’ll smell the garlic pop and the kitchen will brighten. Pour in 1/2 cup broth to deglaze the pan and scrape up the brown bits. Let the liquid reduce by half, concentrating the mushroom flavor.

Step 4:

Lower the heat to medium and stir in the 1 cup heavy cream. Simmer gently until the sauce thickens slightly, about 3–4 minutes. Add the 3/4 cup Parmesan and stir until melted and glossy. Toss in the 5 oz spinach handful by handful until wilted, then splash in the reserved pasta water a little at a time to reach a silky consistency. Season with 1 tbsp lemon juice, salt, pepper, and red pepper flakes if using.

Step 5:

Add the drained pasta straight into the sauce and toss vigorously to coat — you should hear a satisfying clink and see the sauce cling to every strand. Taste and adjust salt, pepper, or lemon. Plate with a sprinkle of chopped parsley, extra Parmesan, and a touch of lemon zest for color and zing.

Pro Tips

• Use room-temperature cream and cheese so they melt smoothly into the sauce instead of clumping.
• Don’t overcrowd the mushrooms — brown them in batches if needed to maximize flavor and crisp edges.
• Reserve pasta water — that starchy splash helps the sauce cling and keeps the dish glossy.
• If your sauce gets too thick, loosen it with small splashes of pasta water rather than more cream.

Common Mistakes to Avoid

• Skipping preheating: Classic rookie move. It changes texture and bake time.
• Overmixing: Leads to dense or chewy results. Mix until just combined.
• Guessing cook time: Always use visual cues or a timer, not just vibes.
• Overcrowding pans: Give your food some breathing room to crisp properly.

Alternatives & Substitutions

• Replace heavy cream with 1/2 cup Greek yogurt + 1/2 cup milk for a lighter sauce (temper the yogurt with hot sauce first to prevent curdling).
• Swap the Parmesan for Pecorino for a sharper bite; use a little less if very salty.
• Use tofu or sautéed chicken breast for extra protein — if using chicken, aim for an internal temp of 165°F.
• To make it gluten-free, use GF pasta; texture stays the same with good brands.

Variations & Tips

• Make it spicy: Add a teaspoon of harissa or more red pepper flakes while sautéing garlic.
• Kid-friendly: Omit the lemon and red pepper flakes and use a milder cheese like mozzarella mixed with Parmesan.
• Herb-forward: Stir in chopped thyme or tarragon at the end for a lovely twist.
• One-pan version: Cook the pasta in extra broth and finish in the mushroom pan for even more flavor (adjust liquid).
• Cheesy bake: Transfer to a baking dish, top with extra Parmesan and broil for 2–3 minutes for browned, bubbly goodness.

FAQ (Frequently Asked Questions)

Can I make this ahead of time?

Yes! Cook the pasta 1 minute under al dente, toss with a touch of olive oil, and store sauce and pasta separately in airtight containers for up to 3 days. Reheat gently on the stove, adding reserved pasta water to revive the sauce.

Can I double the recipe?

Sure thing. Use a wider pan to brown the mushrooms in batches so they caramelize properly. You may need a splash more liquid to get the same saucy finish.

Can I substitute butter with oil?

Technically yes, but you’ll miss that buttery magic. Use ¾ the amount of oil.

How do I know it’s done?

You’ll know it’s done when the pasta is tender with a slight bite (al dente), the mushrooms have golden edges, the sauce coats the back of a spoon, and the spinach has fully wilted.

What if I don’t have ingredient X?

If you don’t have spinach, substitute with baby kale or frozen spinach (squeeze out excess water). No cream? Use milk + a tablespoon of butter and extra cheese for richness.

How I Like to Serve It

I serve this pasta with a crisp green salad and a glass of chilled Sauvignon Blanc on a weeknight, or crusty garlic bread if guests arrive. It makes a cozy solo dinner too — pile it on a plate, turn on a favorite show, and dig in. In colder months it feels like a warm blanket; in spring, the lemon keeps it feeling light.

Notes

• Store leftovers in an airtight container for up to 3 days. Reheat over low heat with a splash of water or milk to revive the sauce.
• Safe cooking temp for added chicken: 165°F.
