Step-by-Step Instructions

Step 1: Preheat & Prep
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13 inch casserole dish with olive oil or non-stick spray.

Step 2: Sauté the Veggies
In a large skillet, heat 1 tbsp olive oil over medium heat.
Add chopped onion and garlic, sautéing for 2-3 minutes until fragrant.
Stir in cauliflower rice and cook for another 5 minutes to release moisture.

Step 3: Combine Ingredients
In a large mixing bowl, combine the sautéed mixture with chicken, broccoli, bell peppers, mozzarella, cheddar, Greek yogurt, chicken broth, and all seasonings.
Mix well until everything is evenly coated and combined.

Step 4: Assemble the Casserole
Pour the mixture into the prepared casserole dish, spreading it out evenly.
Sprinkle the Parmesan cheese over the top.
Cover the dish with aluminum foil.

Step 5: Bake & Broil
Bake in the preheated oven for 20 minutes.
Remove the foil and bake for an additional 10 minutes, or until the top is golden and bubbly.
For extra crispiness, broil for 2-3 minutes at the end.

Step 6: Garnish & Serve
Remove from the oven and let the casserole rest for 5 minutes.
Garnish with chopped parsley before serving.

Tips for the Best Casserole
Use Rotisserie Chicken – A quick shortcut for busy nights.
Drain Cauliflower Well – If using frozen cauliflower rice, squeeze out excess moisture to avoid sogginess.
Steam Broccoli Lightly – Helps retain color and texture without overcooking in the casserole.
Cheese Choice – Swap mozzarella with Monterey Jack or use a smoked cheese for deeper flavor.

Serving Suggestions
Side Salad – Pair with a fresh green salad for added crunch.
Roasted Veggies – Serve alongside roasted carrots or zucchini.
Whole Grain Roll – If you want to add carbs, a warm whole grain roll complements it nicely.
Fruit Salad – A refreshing fruit mix adds a sweet finish.
