Ingredients
Scale
Spaghetti Squash
- 950g cooked spaghetti squash (about 1 large spaghetti squash)
- 1 tablespoon olive oil
- ½ yellow onion, diced
Meat and Seasoning
- 1 lb ground turkey (93/7 lean) – can substitute with ground beef
- 1 teaspoon salt
- ½ teaspoon black pepper
- 2 cloves garlic, minced
Sauces and Mix-ins
- ½ cup ketchup
- ¼ cup mustard
- ¼ cup nonfat plain Greek yogurt
- ½ cup chopped pickles
Dairy and Eggs
- 1 cup shredded lite cheddar cheese, divided
- 3 large eggs
Instructions
- Preheat and Prep: Preheat your oven to 400°F (200°C). Grease a 9×9 inch baking dish to prevent sticking. Cook the spaghetti squash using your preferred method — roasting or microwaving works well — then shred its flesh with a fork until it resembles spaghetti.
- Brown Meat and Sauté Onions: Heat the olive oil in a skillet over medium-high heat. Add the diced yellow onion and cook until softened and translucent, about 3-4 minutes. Add the ground turkey, salt, black pepper, and minced garlic. Cook until the meat is browned and crumbled thoroughly, about 6-8 minutes.
- Combine Ingredients: In a large mixing bowl, combine the cooked and shredded spaghetti squash with the browned ground turkey and onions. Stir in the ketchup, mustard, Greek yogurt, and chopped pickles, mixing thoroughly for even flavor distribution.
- Add Eggs and Cheese: In a separate bowl, whisk the three eggs until fully blended. Add half of the shredded cheddar cheese to the spaghetti squash mixture and stir to combine. Then pour in the whisked eggs and mix well to ensure the casserole will set when baked.
- Bake: Transfer the combined mixture into the prepared baking dish, leveling it out with a spatula. Sprinkle the remaining cheddar cheese evenly over the top. Place in the oven and bake for 1 hour, or until the casserole is firm and the surface turns golden brown.
- Serve: Remove the casserole from the oven and allow it to cool for 15 minutes before serving. This helps the casserole set further and makes for easier slicing and serving.
Notes
- You can substitute ground turkey with ground beef for a richer flavor.
- Spaghetti squash can be cooked by roasting in the oven or microwaving for time efficiency.
- Use lite cheddar cheese to keep the casserole lighter and lower in fat.
- Letting the casserole rest after baking ensures better texture and easier serving.
- Adding Greek yogurt provides creaminess and a slight tang, balancing the ketchup and mustard.
