Instructions

Preheat oven to 375°F (190°C).
Prepare spaghetti squash: Slice squash in half, remove seeds, and bake cut side down for about 30–40 minutes until tender. Scrape into strands using a fork and set aside.
Prepare breading mixture: In a shallow bowl, combine almond flour, Parmesan cheese, garlic powder, oregano, basil, salt, and pepper.
Bread chicken: Dip chicken chunks in beaten eggs, then coat with the almond flour mixture.
Cook chicken: Heat a skillet over medium heat with a little olive oil. Fry chicken chunks until golden brown on all sides (about 4–5 minutes per side). Transfer to a plate.
Assemble casserole: In a baking dish, spread spaghetti squash evenly, layer with cooked chicken, pour marinara sauce over chicken, and sprinkle mozzarella cheese on top.
Bake: Place casserole in the oven for 15–20 minutes, or until cheese is melted and bubbly.
Serve: Garnish with fresh basil leaves and enjoy.

Notes

Spaghetti squash substitute: Spiralized zucchini, cauliflower rice, or low carb pasta are great alternatives.
Make ahead: Prepare chicken and breading in advance, store separately, then assemble and bake when ready.
Herb variations: Add fresh rosemary or thyme for extra depth of flavor.
Meal prep: This dish reheats well in the oven or microwave — perfect for lunches and quick dinners.
