There really aren’t a whole lot of Paleo casseroles out there. Not that there aren’t a lot of awesome Paleo recipes, but generally a casserole needs a ‘binder’ to hold everything together.

You can find a lot of cream or milk based binders, which generally are NOT healthy, because many of the cream based ingredients are processed. No bueno for the body.

Paleo Spaghetti Squash Casserole

I love to cook with spaghetti squash from time to time. Sometimes I’ll just sub it for pasta and make big spaghetti squash and shrimp bowls.

Honestly though, it took me a little while to get up the nerve to make squash at all. I did not like it when I was younger… probably the only vegetable I didn’t like! For so long I said I hated it. But like so many foods we don’t like, we eventually grow a taste for them!

While spaghetti squash is great on its own, it makes the perfect binder for casseroles. You need to try this Paleo spaghetti squash casserole I cooked up last week!

Paleo Spaghetti Squash Casserole Grocery List

Make sure you have the following ingredients on your grocery list!

  • Spaghetti squash
  • Red onion
  • Kale, spinach, or your other favorite dark green leafy veggie
  • Cherry tomatoes
  • Lean ground beef
  • Eggs
  • Minced garlic
  • Garlic powder
  • Oregano
  • Onion powder
  • Olive oil

You could totally jazz up this casserole by adding some sodium-free taco seasoning, topping it with a little bit of cheese, like Fetaβ€”or straight up mixing in some mozzarella to the whole thing. I know cheese isn’t Paleo, but for all your dairy eating folks out there I’m willing to bet it’d be a pretty good choice!

Paleo Spaghetti Squash Casserole





Yield 4 servings


  • 1 spaghetti squash
  • 1 pound 93/7 lean ground beef
  • 2 cups kale or spinach, finely diced
  • 20 cherry tomatoes, halved
  • 1/2 red onion, diced
  • 1 tablespoon minced garlic
  • 1 whole egg
  • 2 teaspoons garlic powder
  • 2 teaspoon oregano
  • 1 teaspoon onion powder
  • 1/2 tablespoon EVOO


  1. Preheat oven to 400 degrees. Cut squash in half lengthwise. Remove seeds. Place cut side down on a baking sheet, and bake for 25 minutes.
  2. While squash is baking, brown ground beef over medium high heat. Drain, and set aside.
  3. While your squash and beef are cooking, prepare vegetables. In a large sauce pan, begin to saute red onion, tomatoes, and garlic with EVOO. Add seasonings. Once onions begin to turn translucent, add spinach and cook down.
  4. Once squash is done, remove from oven and shred the meat of the squash with a fork. Add to pan with sauteed veggies. Add meat, and egg. Mix together thoroughly.
  5. Pour mixture inside a 9 x 9 baking dish, and cook at 400 for 15 minutes.
