Creamy Spaghetti Squash Casserole

Cooking spaghetti squash ahead of time cuts down the cook time. I try to have 1 or 2 pre-cooked spaghetti squash shredded and frozen. That way I can thaw, whip it together and can be cooking while I am making meat balls or chicken to go with. Don't let the length of prep and cook time discourage you from this recipe. It is that good and yummy.

Type: | Servings: 5


  • 1 28 ounce jar/can diced/crushed tomatoes with basil or favorite tomato sauce If you use just tomatoes, sprinkle 1 tablespoon of dried basil or handful of fresh torn basil just before the tomato sauce goes on
  • 1 whole spaghetti squash cooked and shredded
  • 1/4 cup coconut flour
  • 2 whole eggs
  • 1 teaspoon garlic granulated or powdered
  • 1 teaspoon onion granulated or powdered
  • 1 teaspoon oregano dried
  • 1 teaspoon fennel seeds
  • 1.5 cups coconut milk mix the can well before measuring
  • 3 tablespoons butter or ghee cut into small cubes
  • 3 tablespoons nutritional yeast
  • salt and pepper to taste


  1. Pre-cook the squash. Let cool. Using a fork shred squash to look like noodles and put in medium to large mixing bowl. Makes about 3 cups, pending size of squash.

  2. Pre heat oven to 375 degrees Fahrenheit

  3. Meanwhile, squash is cooking in a small mixing bowl combine the coconut flour, eggs, granulated or powdered garlic and onion, dried oregano, fennel seeds, coconut milk, salt and pepper. The consistency will be like a paste.
