Cook Time: 30–35 minutes
Total Time: 45–50 minutes
Servings: 6
Net Carbs: ~5–6g per serving (varies by sauce brand)

🛒 Ingredients

For the Chicken Layer

2 lbs boneless, skinless chicken breasts (or thighs)
1 teaspoon salt
½ teaspoon black pepper
1 teaspoon garlic powder
1 teaspoon Italian seasoning
2 tablespoons olive oil

For the Sauce Layer

2 cups sugar-free marinara sauce
2 cloves garlic, minced
½ teaspoon red pepper flakes (optional)
¼ cup grated Parmesan cheese

For the Cheese Topping

2 cups shredded mozzarella cheese
½ cup freshly grated Parmesan cheese
1 cup shredded provolone (optional but recommended)
2 tablespoons chopped fresh basil or parsley

👩‍🍳 Step-by-Step Instructions

1️⃣ Prep the Chicken

Preheat your oven to 375°F (190°C).

Pat the chicken dry with paper towels. Season both sides with salt, pepper, garlic powder, and Italian seasoning.

Heat olive oil in a large skillet over medium-high heat. Sear the chicken for 3–4 minutes per side until golden brown (it doesn’t need to cook through yet).

Remove from heat and let rest for 5 minutes.

2️⃣ Chop & Layer

Cut the seared chicken into bite-sized chunks or strips.

Lightly grease a 9×13-inch casserole dish. Spread the chicken evenly across the bottom.

3️⃣ Prepare the Sauce

In the same skillet, sauté minced garlic for about 30 seconds until fragrant.

Add marinara sauce, red pepper flakes (if using), and grated Parmesan. Simmer for 3–5 minutes to slightly thicken.

Taste and adjust seasoning if needed.

Pour the sauce evenly over the chicken layer.

4️⃣ Add the Cheese

Sprinkle mozzarella evenly over the top.
Add provolone if using.
Finish with grated Parmesan for that golden crust.

5️⃣ Bake

Bake uncovered for 25–30 minutes, or until:

Cheese is bubbly
Top is golden brown
Internal temperature reaches 165°F (74°C)

For extra browning, broil for 2–3 minutes at the end (watch carefully!).

6️⃣ Garnish & Rest

Let the casserole rest for 5–10 minutes before serving.
Sprinkle with fresh basil or parsley.
