Ingredients for servings

    Spaghetti Squash Lasagna

  • 1 medium spaghetti squash about 4 cups cooked, divided

  • 1.5 cup low-fat ricotta cheese divided

  • 1 large egg

  • teaspoon dried basil

  • teaspoon dried oregano

  • 0.25 teaspoon garlic powder

  • 1.5 cup thick marinara sauce divided

  • 4 cup fresh baby spinach chopped and divided

  • 0.5 cup part-skim mozzarella cheese divided

  • Grape tomatoes optional garnish

  • Red pepper flakes optional garnish

Directions

  • Slice spaghetti squash in half, remove the seeds and bake it flesh side down for 40 minutes at 350°F.

  • To make this recipe quickly, use leftover spaghetti squash. Run a fork into the spaghetti squash to create strands, and throw away the skin. Use a paper towel to pat away excess moisture.

  • Preheat the oven to 350°F.

  • Combine the ricotta with the egg, basil, oregano, and garlic powder.

  • Begin layering by placing 1/2 cup of the marinara sauce in the bottom of a greased 8×8 or 9×9 pan. Continue with 2 cups of cooked spaghetti squash, 3/4 cup of the ricotta mixture, 2 cups fresh chopped spinach, 1/2 cup marinara sauce, and 1/4 cup mozzarella. Repeat the process once with those same amounts (layering spaghetti squash, ricotta, spinach, pasta sauce, and finally mozzarella).

  • Garnish with sliced grape tomatoes, any additional chopped spinach or mozzarella, and red pepper flakes.

  • Bake uncovered for 30 minutes until bubbling.

  • Let it sit for 10 minutes before slicing. To serve immediately, use a slotted spoon and allow any excess liquid to drain out of the pan. Leftovers will be even firmer and slice into nice squares.
