Equipment

  • 1 Large Saucepan – for cooking the mushroom sauce
  • 1 Large Pot – optional, for boiling spaghetti

Ingredients
  

  • 10 –12 ounces dried spaghetti
  • 3 ½ tablespoons extra virgin olive oil divided
  • 1 pound fresh mushrooms cleaned and de-stemmed (½ thinly sliced, ½ finely diced)
  • 2 –3 cloves garlic finely chopped
  • 1 ½ tablespoons fresh thyme leaves
  • ¾ teaspoon Italian seasoning
  • 1 tablespoon tomato paste
  • ½ cup red wine
  • 1 14.5-ounce can fire-roasted tomatoes
  • 1 ½ cups prepared tomato pasta sauce
  • ½ cup grated Parmesan or Pecorino Romano cheese divided (or vegan alternative)
  • ¼ cup fresh basil chopped and divided
  • Kosher salt to taste
  • Ground black pepper to taste

Instructions
 

  • Optional – Prepare the Spaghetti Pasta: Bring a large pot of water to a rolling boil over high heat.
    Once boiling, generously season the water with salt to enhance the pasta’s flavor.
    Add the dried spaghetti and cook until it is just one minute shy of al dente, following the package instructions (typically 8–9 minutes).
    Drain the pasta, reserving about 1 cup of the cooking water for later use.
    Set both the cooked spaghetti and pasta water aside.
    Tip: You can start this step while preparing the mushrooms so everything comes together seamlessly.
  • Sauté the Sliced Mushrooms: Heat 2 tablespoons of olive oil in a large saucepan over medium-high heat until it shimmers.
    Carefully add the thinly sliced mushrooms in a single layer and let them cook undisturbed for 4 minutes.
    This allows them to brown beautifully. After 4 minutes, stir the mushrooms gently, then continue cooking for an additional 3–5 minutes, stirring occasionally, until they are golden brown and tender.
    Season lightly with salt and pepper to enhance their natural earthy flavor. Remove the mushrooms from the pan and set aside on a plate.
  • Cook the Diced Mushrooms: Reduce the heat to medium and add the remaining 1 ½ tablespoons of olive oil to the same pan.
    Add the finely diced mushrooms and cook them undisturbed for 2 minutes.
    Stir occasionally and continue cooking until the mushrooms turn a lovely golden color, approximately 2–3 minutes.
    This step builds a deep, concentrated mushroom flavor that forms the base of your sauce.
  • Infuse with Garlic and Herbs: Once the diced mushrooms are golden, stir in the finely chopped garlic, fresh thyme leaves, and Italian seasoning.
    Season lightly with salt and pepper.
    Cook this mixture for about 1 minute, or until fragrant, stirring constantly to prevent burning.
    The combination of herbs and garlic will create a savory, aromatic foundation for the sauce.
  • Add and Caramelize Tomato Paste: Add 1 tablespoon of tomato paste to the pan and stir to coat the mushrooms evenly.
    Cook for 1–2 minutes, allowing the tomato paste to caramelize slightly.
    This enhances its natural sweetness and adds a rich depth to the sauce.
    Be sure to stir continuously so the paste doesn’t stick or burn.
  • Deglaze with Red Wine: Pour ½ cup of red wine into the pan, using a wooden spoon to scrape up any browned bits from the bottom.
    These bits, called “fond,” add intense flavor to the sauce.
    Let the wine simmer for 2–3 minutes, allowing most of it to evaporate while leaving a subtle, savory richness behind.
  • Add Tomatoes and Simmer: Stir in the fire-roasted tomatoes along with their juices and the prepared tomato pasta sauce.
    Increase the heat to bring the sauce to a gentle boil, then immediately reduce the heat to maintain a steady, gentle simmer.
    Add ¼ cup of grated Parmesan or Pecorino Romano cheese and season with salt and pepper to taste.
    Let the sauce simmer for 10–12 minutes, stirring occasionally, until it thickens slightly or reaches your preferred consistency.
    Half of the chopped fresh basil can also be added during this simmering step for a fragrant, herbal note.
  • Combine Spaghetti and Sautéed Mushrooms: Add the cooked spaghetti noodles and the reserved sautéed sliced mushrooms to the simmering sauce.
    Using tongs or two large spoons, gently toss the pasta and sauce together for 1–2 minutes until the spaghetti is evenly coated.
    If the sauce seems too thick, add a splash of the reserved pasta water, 1–2 tablespoons at a time, until the sauce reaches your desired consistency.
    Taste and adjust seasoning with salt and pepper as needed.
  • Serve and Garnish: Transfer the mushroom spaghetti to individual serving bowls or a large serving platter.
    Sprinkle the remaining grated cheese over the top and garnish with the leftover fresh basil.
    Serve immediately while hot for the best flavor.
    This dish pairs beautifully with a light side salad or crusty bread for a complete Italian-inspired meal.

Notes

  • Use a mix of mushroom varieties, such as cremini, button, or shiitake, for a richer flavor and texture.
  • For a chunkier, rustic sauce, keep half the mushrooms sliced; for a smoother sauce, finely dice all mushrooms.
  • High-quality olive oil and fresh herbs make a noticeable difference in flavor.
  • Adjust the red wine and tomato ratios to suit your taste preference or dietary needs.
  • Reserve some pasta cooking water to adjust sauce consistency without diluting flavor.
  • This recipe can be easily doubled for larger gatherings or scaled down for smaller portions.
  • Optional: use vegan Parmesan and plant-based pasta for a completely plant-based version.

Chef’s Secrets: Elevating Mushroom Spaghetti Flavor

The key to an unforgettable mushroom spaghetti sauce is layering flavors thoughtfully.

Start by sautéing sliced mushrooms undisturbed to develop a deep, caramelized richness, then separately cook the diced mushrooms to intensify the base.

Caramelizing the tomato paste adds subtle sweetness and depth, while deglazing with red wine brings a luxurious, slightly acidic complexity.

Fresh herbs, added at the right stage, elevate the aroma and taste, making the sauce taste restaurant-quality without extra effort.

Using high-quality ingredients—especially olive oil, mushrooms, and pasta—can dramatically enhance the final dish.

Serving Suggestions: Perfect Pairings for Pasta

This hearty mushroom sauce pairs beautifully with any long pasta, from spaghetti to fettuccine, but also works with short pasta like penne for a more rustic presentation.

Serve with freshly grated Parmesan or Pecorino Romano for extra savory richness.

A light side salad, roasted vegetables, or garlic bread complements the flavors while keeping the meal balanced.

For a cozy weeknight dinner, pair with a glass of red wine, such as Chianti or Pinot Noir, to echo the subtle wine notes in the sauce.

Storage Tips: Keeping Sauce Fresh

Store leftover mushroom sauce in an airtight container in the refrigerator for up to 4 days.

When reheating, warm gently on the stovetop over low heat, adding a splash of pasta water to restore the sauce’s silky consistency.

For longer storage, freeze the sauce in a freezer-safe container for 4–6 months. Thaw overnight in the refrigerator before reheating.

Cooked pasta should be stored separately, as mixing it with the sauce can cause it to become overly soft when reheated.

Frequently Asked Questions

1. Can I use dried mushrooms instead of fresh?

Yes, but rehydrate dried mushrooms in warm water for 20–30 minutes before using.

Drain and reserve some soaking liquid to enhance the sauce’s flavor. Keep in mind that dried mushrooms have a more concentrated taste, so you may need less than the recipe calls for.

2. Can I skip the red wine?

Absolutely! If you prefer a non-alcoholic version, substitute the wine with an equal amount of vegetable broth or unsweetened grape juice.

While the flavor profile changes slightly, the sauce will remain rich and savory.

3. How can I make this recipe vegan?

Use a plant-based pasta and substitute Parmesan with a vegan alternative or nutritional yeast. Ensure your tomato pasta sauce contains no dairy, and the dish becomes entirely plant-based without sacrificing flavor.

4. Can I prepare the sauce ahead of time?

Yes! The sauce can be made a day in advance and stored in the refrigerator.

Reheat gently before serving and toss with freshly cooked pasta for optimal texture.

5. What’s the best way to prevent soggy pasta?

Always cook pasta slightly under al dente if you plan to mix it with the sauce later.

Toss immediately before serving and avoid overcooking. Reserving pasta water allows you to loosen the sauce without making the pasta watery.
