Preheat the oven to 400°F (204°C) and grease a 3-quart baking dish.

Meanwhile, heat the 2 bags of frozen cauliflower rice (10 ounces each) and 1 bag of frozen broccoli cuts (16 ounces) per package instructions. Drain excess water well to avoid sogginess.
Let the chicken cool for 5 minutes, then chop into bite-sized pieces.
In a large bowl, combine the cooked cauliflower rice, broccoli, chopped chicken, 2 whisked large eggs, 3 cups shredded mozzarella cheese, remaining 2 teaspoons salt, 2 teaspoons garlic powder, 2 teaspoons onion powder, and 2 tablespoons melted unsalted butter. Mix thoroughly.
Transfer the mixture to the prepared baking dish and top with 1 cup shredded Italian blend cheese.
Bake for 50 minutes until the cheese is melted and beginning to brown. Allow the casserole to cool for 10 minutes before serving.

Dietary Substitutions to Customize Your Broccoli Cauliflower Rice Chicken Casserole

One of my favorite parts about this healthy chicken casserole with broccoli cauliflower rice is how flexible it is. Got picky eaters or special diets? No problem. Here’s how to tweak it while keeping that delicious vibe.

Protein swaps: Ditch chicken for turkey breast to trim fat more, or go plant-based with firm tofu or tempeh. Bake the tofu slices just like the chicken.
Veggie changes: Swap broccoli for asparagus or green beans if that’s what you’ve got. Cauliflower rice? Try zucchini rice for even fewer carbs.
Dairy alternatives: Use plant-based mozzarella and Italian blend cheese. Skip eggs for flax eggs (1 tbsp ground flax + 3 tbsp water per egg).
Flavor boosters: Add herbs like thyme or spice it with paprika. For creaminess without dairy, a dollop of coconut cream works wonders.

These easy weeknight meals with broccoli cauliflower rice chicken casserole adapt to gluten-free, vegan, low-calorie, or keto needs seamlessly. My friend made the tofu version and said it was her new go-to.
