Ingredients

For the Mushroom Sauce

  • 1 pound Fresh Mushrooms – cleaned, de-stemmed, divided (½ thinly sliced & ½ finely diced)
  • 3 ½ tablespoons Extra Virgin Olive Oil – divided
  • 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, plus more for serving (or vegan alternative)
  • ¼ cup Fresh Basil – chopped & divided
  • Kosher Salt – to taste
  • Ground Black Pepper – to taste

For the Spaghetti

  • 10-12 ounces Dried Spaghetti

Instructions

  1. Optional – Cook Spaghetti Pasta: Bring a large pot of water to a rolling boil. Generously season the boiling water with kosher salt. Add the spaghetti noodles and cook until they are one minute shy of al dente, about 8-9 minutes depending on the brand. Drain the pasta, reserving 1 cup of the pasta cooking water. Set both aside.
  2. Sauté the Sliced Mushrooms: Heat 2 tablespoons of extra virgin olive oil in a large saucepan over medium-high heat until shimmering. Add the thinly sliced mushrooms and cook without stirring for 4 minutes to allow browning. Stir the mushrooms and continue to cook for an additional 3-5 minutes until golden brown and tender. Season with salt and pepper. Remove the mushrooms to a plate and set aside.
  3. Start the Mushroom Sauce: Reduce heat to medium and add the remaining 1 ½ tablespoons of olive oil to the pan. Add the finely diced mushrooms and cook undisturbed for 2 minutes. Stir and continue cooking, stirring occasionally, for an additional 2-3 minutes until golden brown.
  4. Add Aromatics and Seasoning: Stir in the finely chopped garlic, fresh thyme leaves, and Italian seasoning. Season with salt and pepper. Cook for about 1 minute until fragrant.
  5. Add Tomato Paste: Stir in the tomato paste and cook, stirring frequently, for 1-2 minutes until caramelized and deepened in flavor.
  6. Deglaze the Pan: Pour in the red wine and use the edge of a wooden spoon to scrape up any browned bits from the bottom of the pan. Allow the wine to simmer until mostly evaporated, about 2-3 minutes.
  7. Add Tomatoes and Simmer: Stir in the fire-roasted tomatoes with juices and the prepared tomato pasta sauce. Bring to a rapid simmer, then reduce the heat to maintain a gentle simmer. Stir in ¼ cup of the grated cheese and season with salt and pepper to taste. Let the sauce simmer gently for 10-12 minutes or until slightly thickened.
  8. Add Fresh Basil: Stir in half of the chopped fresh basil into the sauce.
  9. Combine Pasta, Sautéed Mushrooms, and Sauce: Add the cooked spaghetti and reserved sautéed sliced mushrooms to the sauce. Toss gently using tongs or two spoons for 1-2 minutes to coat the pasta evenly with the sauce. If the sauce is too thick, add reserved pasta cooking water a splash at a time (usually ¼ to ½ cup) until desired consistency is reached.
  10. Adjust Seasoning and Serve: Taste and adjust seasoning with additional salt and pepper if needed. Transfer the mushroom sauce-coated spaghetti to serving bowls. Garnish with the remaining grated cheese and fresh basil. Serve immediately and enjoy.

Notes

  • You can use any variety of fresh mushrooms you prefer; cremini, button, shiitake, or a mix work well.
  • For a traditional tomato sauce, finely dice all the mushrooms and omit step 2 where mushrooms are sautéed sliced.
  • Use crushed tomatoes instead of diced if you prefer a less chunky sauce texture.
  • Choose a high-quality jarred tomato pasta sauce that suits your flavor preferences for best results.
  • If sauce tastes too sweet or too acidic, adjustments can be made by balancing with salt, acidity, or sweetness as per preference.
  • Store leftover sauce in an airtight container in the refrigerator for up to 4 days or freeze for up to 4-6 months.
  • To scale the recipe, adjust the servings using the sliding scale in the recipe card or multiply ingredients proportionally.
  • Feel free to ask questions or request clarifications in the comments if needed.
