Ingredients

• 2 tablespoons extra virgin olive oil
• 1 large onion, roughly chopped
• 2 medium carrots, roughly chopped
• 1 rib celery, roughly chopped
• 3 cloves garlic, grated or minced
• ½ teaspoon dried rosemary
• 3 bay leaves
• ½ cup tomato paste
• 2 pounds mushrooms, preferably a mixture of white and cremini mushrooms
• 1 teaspoon salt, plus more to taste
• ¼ teaspoon black pepper
• 1 tablespoon balsamic vinegar, plus more to taste
• 12 ounces pasta, such as tagliatelle, fettuccine, or pappardelle
• ¼ cup grated Parmesan cheese, for serving
• 1 handful fresh basil leaves, for serving
• Reserved pasta water, as needed

Instructions

1. Prepare the mushrooms: Finely chop the mushrooms using a food processor in several batches, keeping the texture coarse rather than turning them into a paste. Alternatively, chop them by hand.
2. Chop the vegetables: Pulse or finely chop the onion, carrots, and celery.
3. Sauté the vegetables: Heat the olive oil in a large skillet or Dutch oven over medium heat. Add the onion, carrots, and celery. Cook for about 5 minutes, stirring frequently, until softened.
4. Add the aromatics: Stir in the garlic, dried rosemary, bay leaves, and tomato paste. Cook for approximately 3 minutes, allowing the tomato paste to darken slightly and develop a deeper flavor.
5. Cook the mushrooms: Add the chopped mushrooms, salt, and black pepper. Increase the heat to medium-high and cook for about 20 minutes, stirring occasionally.
6. Thicken the sauce: Continue cooking until the mushrooms release their moisture and most of the liquid evaporates. The ragu should become thick, rich, and almost creamy.
7. Finish the ragu: Stir in the balsamic vinegar. Remove the bay leaves and taste the sauce, adjusting the salt, pepper, and vinegar as needed.
8. Cook the pasta: Bring a large pot of salted water to a boil. Cook the pasta according to the package instructions. Before draining, reserve 1 cup of pasta water.
9. Combine everything: Add the drained pasta to the mushroom ragu with approximately ¼ cup of reserved pasta water. Toss over medium heat until the pasta is evenly coated. Add more pasta water if needed.
10. Serve: Divide the pasta among serving bowls and finish with grated Parmesan and fresh basil.

Serving and Storage Tips

• Serve with Parmesan: Freshly grated Parmesan adds a salty, savory finish that complements the earthy mushrooms.
• Add fresh herbs: Basil is delicious, but chopped parsley or fresh thyme also works beautifully.
• Pair with garlic bread: Serve with crusty bread to soak up the rich mushroom sauce.
• Include a side salad: A green salad with a light vinaigrette balances the richness of the pasta.
• Make it a complete meal: Pair with roasted vegetables, steamed green beans, or sautéed spinach.
• Store leftovers: Refrigerate the sauce or prepared pasta in an airtight container within 2 hours of cooking and consume within 3–4 days.
• Reheat gently: Warm leftovers in a skillet over medium-low heat with a splash of water or vegetable broth to loosen the sauce.
• Freeze the sauce: Freeze the mushroom ragu separately from the pasta in airtight, freezer-safe containers for up to 3 months for best quality.
• Thaw safely: Defrost frozen sauce in the refrigerator overnight before reheating thoroughly.
• Make ahead: Prepare the ragu a day in advance. Its flavors can develop further overnight, making it ideal for meal preparation.

Variations

1. Creamy Mushroom Ragu

Add ¼–½ cup heavy cream or unsweetened cooking cream after the mushrooms have cooked down. Simmer gently for a few minutes until the sauce becomes silky. This version is perfect for fettuccine or pappardelle.

2. Vegan Mushroom Ragu

Replace the Parmesan with nutritional yeast or a plant-based Parmesan alternative. Use egg-free pasta and check that all ingredients are plant-based. The mushrooms provide plenty of savory flavor without needing dairy.

3. Gluten-Free Mushroom Ragu

Use your favorite gluten-free pasta, such as brown rice, corn, or chickpea pasta. Check the labels on the tomato paste and other packaged ingredients to ensure they meet your dietary needs. Reserve some pasta water and toss gently to avoid breaking delicate gluten-free noodles.

4. Spicy Mushroom Ragu

Add ¼–½ teaspoon red pepper flakes along with the garlic and rosemary. Increase the amount to taste if you prefer a stronger kick. The gentle heat pairs especially well with tomato paste and earthy mushrooms.

5. Mushroom and Lentil Ragu

Add 1 cup cooked brown or green lentils after the mushrooms begin to soften. Simmer until everything is thick and well combined. Lentils make the sauce heartier and add plant-based protein and texture.

6. Mushroom and Walnut Ragu

Stir in ½ cup finely chopped toasted walnuts near the end of cooking. They add a pleasant crunch and a rich, nutty taste that complements the mushrooms. This variation is especially delicious with pappardelle.

7. Porcini Mushroom Ragu

Replace part of the fresh mushrooms with rehydrated dried porcini mushrooms. Add a small amount of strained soaking liquid to the sauce for extra depth, taking care to leave any grit behind. This creates a more intense, woodsy mushroom flavor.

8. Garlic Lover’s Mushroom Ragu

Increase the garlic from 3 cloves to 5 or 6. Add some of it during sautéing and stir the rest in near the end for a fresher garlic aroma. This is a wonderful choice for garlic bread lovers.

9. Mushroom Ragu With Spinach

Stir in 2 cups fresh baby spinach during the final few minutes of cooking. Allow it to wilt into the sauce before adding the pasta. Spinach adds color and makes the dish feel even more vegetable-packed.

10. Mushroom Ragu With Sun-Dried Tomatoes

Chop ⅓ cup oil-packed sun-dried tomatoes and add them with the tomato paste. Their concentrated sweetness and tanginess bring extra complexity to the sauce. Reduce the added salt slightly if the tomatoes are heavily salted.
