Step‑by‑Step Instructions for Mushroom Spaghetti Aglio Olio
Step 1: Cook the Spaghetti
Bring a large pot of salted water to a rolling boil. Add your spaghetti and cook according to package instructions until al dente, usually about 8-10 minutes. Remember to reserve 1 cup of the pasta water before draining the spaghetti into a colander. This water will help create a silky sauce for your Mushroom Spaghetti Aglio Olio.
Step 2: Sauté the Mushrooms
In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Add both the button and oyster mushrooms, sautéing them for about 5-7 minutes until they become golden brown and tender. Stir occasionally to ensure even cooking and prevent the mushrooms from sticking. You’ll know they’re ready when they release their juices and look appetizingly caramelized.
Step 3: Add Garlic and Remaining Oil
Lower the heat to medium and pour in the remaining olive oil along with the finely chopped garlic. Sauté this mixture for about 2 minutes, stirring continuously, until the garlic becomes fragrant and lightly golden but not burnt. This aromatic blend lays the foundation for the rich flavors of the Mushroom Spaghetti Aglio Olio.
Step 4: Create the Sauce
Sprinkle in the chili flakes and pour in the reserved pasta water, carefully mixing in salt to taste. Allow the sauce to simmer for 2-3 minutes, stirring frequently until it begins to emulsify and thicken slightly. The key here is to glaze the mushrooms in the sauce, ensuring they soak up all that delicious garlicky flavor.
Step 5: Combine the Ingredients
Add the drained spaghetti directly into the pan with the mushroom and garlic sauce. Toss everything together with a pair of tongs for about a minute, making sure the pasta is thoroughly coated in the luscious sauce. If it seems a bit dry, add a splash more reserved pasta water to achieve the desired consistency for your Mushroom Spaghetti Aglio Olio.
Step 6: Serve and Garnish
Remove the pan from the heat and fold in the freshly chopped parsley, giving it a final toss for a fresh touch. Plate your Mushroom Spaghetti Aglio Olio and generously sprinkle grated Parmesan on top. This will enhance the dish’s flavors, making each bite a delightful experience, best enjoyed right away.
