Spaghetti Squash Casserole


Strands of tender squash replace pasta for a more flavorful version of spaghetti pie casserole. Not to mention, spaghetti squash is a low-carb alternative to pasta and saves more than 150 calories per serving compared to a traditional recipe. A sprinkling of nutty fontina cheese melts into a gooey topping.

6 cups


  • 1 (2 1/2 to 3 pound) spaghetti squash, cut in half lengthwise and seeds removed

  • 2 tablespoons water

  • 1 pound lean ground beef

  • 1 medium shallot, sliced

  • 2 cloves garlic, minced

  • 1 ½ teaspoons Italian seasoning

  • ½ teaspoon plus 1/8 teaspoon salt

  • ½ teaspoon ground pepper

  • 1 (28 ounce) can no-salt-added crushed tomatoes

  • 1 cup shredded fontina cheese

  • Fresh basil for garnish


  1. Preheat oven to 400 degrees F.

  2. Place squash, cut-side down, in a microwave-safe dish; add water. Microwave, uncovered, on High until tender, about 10 minutes. (Alternatively, place squash halves cut-side down on a rimmed baking sheet. Bake at 400 degrees F until tender, 40 to 50 minutes.)

  3. Meanwhile, cook ground beef in a large ovenproof skillet over medium-high heat, breaking it up with a wooden spoon, until no longer pink, 5 to 7 minutes. Add shallot, garlic, Italian seasoning, salt and pepper and cook, stirring, for 1 minute. Stir in tomatoes and bring to a boil. Reduce heat to maintain a simmer.

  4. Use a fork to scrape the squash flesh from the shells into the sauce; stir to combine. Top with cheese. Transfer the pan to the oven and bake until bubbling, about 15 minutes. Let stand for 5 minutes. Serve sprinkled with basil, if desired.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
