Step‑by‑Step Instructions for Mushroom Spaghetti
Step 1: Cook the Spaghetti
Begin by bringing a large pot of salted water to a boil over high heat. Add 10 oz (280 grams) of spaghetti and cook according to the package instructions until al dente, typically about 8-10 minutes. As the pasta cooks, reserve ½ cup of the pasta water before draining. This starchy water will help create a smoother sauce later.
Step 2: Prepare the Mushrooms
While the pasta cooks, rinse, dry, and slice 1 lb (450 grams) of your chosen mushrooms. Portobello or cremini varieties work wonderfully for this Mushroom Spaghetti. Ensure the slices are uniform in thickness, about ¼ inch, for even cooking. The earthy aroma of the mushrooms will soon fill your kitchen as you sauté them.
Step 3: Sauté Garlic and Chili Flakes
In a large skillet, heat 2 tablespoons of extra virgin olive oil over medium heat. As the oil warms, add the minced garlic (4 large cloves) and a pinch of chili flakes if you desire a bit of heat. Sauté for approximately 1 minute until fragrant, letting the garlic turn a golden hue without burning, which brings out its delicious flavor.
Step 4: Cook the Mushrooms
Add the sliced mushrooms to the skillet with the garlic and chili flakes. Season generously with salt and pepper to taste. Sauté for about 7 minutes, stirring occasionally, until the mushrooms have released their moisture and become beautifully browned. The deep color and aroma will signal that they are perfectly cooked for the Mushroom Spaghetti.
Step 5: Combine Spaghetti and Sauce
Once the mushrooms are ready, toss the cooked spaghetti into the skillet. Gradually add the reserved pasta water, starting with ¼ cup. Mix until the spaghetti is well coated, keeping the sauce silky and moist. Add the chopped fresh parsley (about 3 tablespoons) and ⅓ cup of freshly grated Parmesan cheese, stirring to combine everything harmoniously.
Step 6: Serve the Dish
Remove the skillet from the heat and taste for seasoning, adjusting with more salt and pepper if needed. Serve the Mushroom Spaghetti immediately, topped with additional Parmesan cheese and a sprinkle of chili flakes if you love extra heat. Enjoy the warm, comforting flavors that make this dish a family favorite!

Mushroom Spaghetti Recipe FAQs
How do I know if my mushrooms are ripe and fresh?

What’s the best way to store leftover Mushroom Spaghetti?
To keep your Mushroom Spaghetti fresh, store any leftovers in an airtight container in the fridge for up to 2 days. Make sure it has cooled completely before sealing to maintain its quality. For best results, reheat gently in a skillet or microwave, adding a splash of water or broth to revive the sauce.

What if my pasta turns mushy while cooking?
Mushy pasta is often the result of overcooking or using too much water. Always cook pasta according to the package instructions and taste it a minute or two before the recommended time. Drain it promptly once al dente; it will continue to cook slightly after draining due to residual heat.
