Instructions

  1. Step 1: Bring 4 quarts of water to a rolling boil in a large pot; add 1 tablespoon salt and 8 ounces spaghetti. Cook for 8-10 minutes until al dente, then drain, reserving 1/2 cup pasta water.
  2. Step 2: Heat 2 tablespoons olive oil in a large skillet over medium heat. Add 1 cup sliced mushrooms and cook for 5 minutes until they release moisture and brown slightly.
  3. Step 3: Add 3 minced garlic cloves and 1 tablespoon fresh thyme leaves, stirring for 1 minute until fragrant without browning.
  4. Step 4: Stir in 1/2 cup vegetable broth and the reserved 1/2 cup pasta water, then add the drained spaghetti and 1/4 cup grated parmesan. Toss for 2 minutes until sauce thickens and coats pasta.
  5. Step 5: Season with salt and freshly ground black pepper to taste, then serve immediately.

Can I substitute ingredients in One-Pot Pasta with Sautéed Mushrooms and Thyme?

How do I scale One-Pot Pasta with Sautéed Mushrooms and Thyme for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
