Instructions

  1. Preheat the oven to 375 F. Cook the 16 ounces whole wheat spaghetti according to package directions. Drain and set aside in a large baking dish.
  2. Meanwhile, place half of the 2 pounds button mushrooms in a food processor and pulse a few times, just until small chopped. Repeat with the remaining mushrooms.
  3. Heat the 1 tablespoon olive oil in a large deep pan over medium-high heat. Add the mushrooms and cook, stirring occasionally, for 8-10 minutes.
  4. Once the mushrooms reduced their size to about half of the amount, stir in the 1 teaspoon dried oregano, 1 tablespoon smoked paprika, 1 onion (diced), and 3-4 garlic cloves (minced). Continue to cook for 5-6 minutes, stirring frequently.
  5. Stir in the 24 ounces marinara sauce and simmer for a couple of minutes. Season the sauce with Kosher salt and pepper.
  6. Pour the sauce over the cooked spaghetti and gently stir to combine; sprinkle with the 1 cup shredded mozzarella and 1/2 cup grated parmesan cheese. Bake the casserole for 25-30 minutes, or until bubbly and the cheese is melted.
  7. Garnish with freshly chopped fresh parsley, if desired, and serve warm.

Notes

  • Storing leftovers: Store in an airtight container in the refrigerator for 3 to 5 days. Reheat individual servings in the microwave or the entire pan, covered with foil, in the oven at 350ºF for about 20 to 30 minutes or until heated through.
  • Make ahead: You can prepare this dish up to 24 hours in advance. Cover and refrigerate until baking. An extra 5-10 minutes may need to be added to the bake time if it's cold from the fridge.
  • Freezing: If you plan to freeze this, I recommend undercooking the pasta a bit. Cover the pan with plastic wrap and then again with foil. Freeze for up to 3 months. When you’re ready to enjoy, thaw in the fridge, remove plastic wrap, and bake according to directions.
