Ground Turkey Spaghetti Squash Casserole Ingredients
For the Casserole Base
โข Spaghetti Squash โ This low-carb alternative to pasta is the heart of your casserole; ensure itโs fresh and firm for the best texture.
โข Garlic (2 cloves) โ Adds a fragrant aroma; you can swap in ยฝ teaspoon of garlic powder if you can’t find fresh.
โข Onion (1 medium) โ Enhances the overall flavor; opt for a yellow or white onion for a sweet touch.
โข Oil (1 tsp) โ Essential for sautรฉing; olive oil works wonders here, but any cooking oil will do.
โข Ground Turkey (1 lb) โ The protein powerhouse of this dish; for a vegetarian version, replace it with cooked lentils.
โข Organic Cream of Mushroom Soup (11 oz) โ Creates a rich, creamy texture; if mushrooms arenโt your thing, a non-mushroom version can be used.
โข Tomato Sauce (1 cup, low sodium) โ Offers acidity and moisture to balance other flavors; homemade sauce is a great option!
โข Cornstarch (1 tbsp) โ Helps thicken your meat sauce but can be omitted if you prefer a lighter mix.
For the Cheesy Topping
โข Tex Mex Cheese (1 + 1/2 cups, shredded) โ Adds a creamy richness; feel free to substitute with your favorite cheese like cheddar or mozzarella.
โข Panko Breadcrumbs (1/2 cup + 1/2 cup for topping) โ Gives that delightful crunch on top; swap with whole wheat breadcrumbs for a healthier option.
โข Butter/Coconut Oil (2 tbsp, melted) โ Provides richness to the topping; using coconut oil offers a lighter flavor profile.

How to Make Ground Turkey Spaghetti Squash Casserole
Preheat the oven to 375ยฐF. Start by preparing a baking sheet lined with parchment paper to simplify cleanup later on. This step ensures your casserole bakes evenly.
Cut the spaghetti squash in half lengthwise and scoop out the seeds. Place the squash cut side down on the baking sheet. Bake for about 30 minutes, or until it’s soft and easily pierced with a fork.
Sautรฉ the garlic and onion in a skillet with 1 teaspoon of oil for about 4 minutes, until fragrant and translucent. The aroma will fill your kitchen, bringing a comforting warmth that invites everyone to the table.
Add the ground turkey to the skillet and cook for 7 minutes until itโs browned. Mix in the cream of mushroom soup, tomato sauce, and cornstarch, simmering for 5 minutes until thickened. This is where the flavors meld together, creating a savory base.
Combine the meat mixture with the baked spaghetti squash, 1 cup of cheese, and ยฝ cup of breadcrumbs in a large bowl. Stir until everything is evenly mixed; the spaghetti squash should be coated in that rich, delicious sauce.
Prepare the topping by mixing the melted butter, remaining cheese, and breadcrumbs in a separate bowl. This will provide a delightful crunch when baked!
Reduce the oven temperature to 350ยฐF, then transfer the spaghetti squash mixture to a greased baking dish. Sprinkle the cheesy topping evenly over the casserole and bake uncovered for 35 minutes, or until bubbly and golden. If you like a crispy top, broil for an extra 5 minutes.
Cool the casserole for 15 minutes before slicing into 8 pieces. This helps it set and makes serving easier. Enjoy each warm slice fresh out of the oven!
Optional: Garnish with fresh herbs like parsley or basil for a pop of color and extra flavor.
