Ingredients

  • 8 ounces spaghetti of choice (white, whole wheat, or gluten-free)
  • 3 tablespoons olive oil divided
  • 3/4 cup finely chopped onion about 1/2 a large onion
  • 1 cup grated carrot
  • 8 ounces crimini or button mushrooms diced small
  • 2-3 cloves garlic minced
  • 3/4 teaspoon salt divided
  • 1/2 tablespoon Italian seasoning
  • 2 cups loosely packed baby spinach roughly chopped
  • 1.5 cups canned crushed tomatoes
  • 2 large eggs beaten
  • 3 tablespoons grated parmesan cheese
  • 1/2 cup shredded mozzarella cheese or to taste

Instructions

  • Preheat oven to 375 ℉. Grease a 9-inch pie plate or round baking dish with oil.
  • Cook your spaghetti according to package directions. Meanwhile, prep your vegetables. Once the spaghetti is ‘al dente’, drain in a colander then place in a large bowl.
  • To make sauce, return the pot you cooked the pasta in (or another pot if you prefer) to the stove and heat 2 tablespoons of olive oil over medium-high heat. Add chopped onion and carrot and cook for 2 to 3 minutes.
  • Add chopped mushroom and saute until the mushrooms begin to brown. Add garlic, 1/2 teaspoon salt, and Italian seasoning and cook for 2 more minutes or until all the vegetables are soft. Stir in spinach and then crushed tomato. Lower heat and simmer while you prepare the spaghetti “crust”.
  • To the cooked spaghetti, add the remaining tablespoon of olive oil, eggs, parmesan cheese, the rest of the salt, and a few grinds of pepper. Mix well then press the spaghetti mixture into the bottom and up the sides of your pie pan.
  • Spoon the veggie sauce into the center of the spaghetti. Spread into an even layer, leaving an-inch boarder of spaghetti not covered in sauce. Sprinkle mozzarella cheese over the top.
  • Bake until cheese is golden brown, 20 to 22minutes. Allow to cool for 5 to 10 minutes, then cut into wedges and serve.
