While I’m happy to eat plant-based meals that put the vegetables front and center, I’m usually not one for faux meat. But I’m happy to make an exception when I’ve found a DIY meat substitute that’s as delicious as the one in this vegetarian ragu.

Made from ground mushrooms and walnuts, it has a meaty texture, deep umami flavor and — importantly — plenty of fat. Even better, it’s quick and easy to make yourself. Simply put a 2-to-1 ratio (by weight) of mushrooms to walnuts in a food processor, grind it up, and cook in your oil of choice until deeply browned. I learned this trick from another recipe developer, who used it in chili, and I’ve been experimenting with it ever since.

For a weeknight ragu, stir in a jar of prepared marinara sauce and a Parmesan cheese rind. You can cut the rind off of any block of Parm, and it’ll bring a bit more umami to the final dish. I like to serve the sauce with spaghetti, topped with Parmesan cheese and parsley.

Spaghetti with Mushroom Ragu

For a vegan option, simply omit the Parmesan cheese and rind.


Spaghetti with Mushroom Ragu

Ingredients
  • 1 pound dry spaghetti
  • Kosher salt
  • 8 ounces button or cremini mushrooms, quartered
  • 4 ounces (1 heaping cup) raw walnuts
  • 1/4 cup extra-virgin olive oil
  • 1 (24-ounce) jar marinara sauce, such as Rao’s
  • 1/4 cup freshly grated Parmesan cheese, plus 1 to 2 inches of rind
  • Chopped fresh parsley, for serving (optional)
Instructions
  • Bring a large pot of salted water to a boil over high heat. Add the pasta and cook until just al dente, about 9 minutes. Drain, reserving 1/2 cup of the pasta cooking water.
  • While the water is heating and the pasta is cooking, combine the mushrooms and walnuts in a food processor. Pulse until the mixture is finely chopped and looks like ground meat, 8 to 10 1-second pulses.
  • Heat the olive oil in a large Dutch oven or large, deep skillet over medium-high heat. When the oil is shimmering, add the mushrooms and walnuts and cook, stirring frequently, until the mixture looks dry and has formed a dark brown fond on the bottom of the pan, 8 to 10 minutes. Season with salt.
  • Add the marinara sauce and the Parmesan rind. Bring to a simmer, scraping up the browned bits off the bottom of the pan, reduce the heat to low and cook until flavorful, 5 to 7 minutes. Remove and discard the Parmesan rind.
  • Add the drained pasta and stir well to coat. Stir in some of the reserved pasta water, 1 tablespoon at a time, if the sauce is too thick to easily coat the pasta. Serve topped with the Parmesan and parsley, if desired.
