Description

What makes this casserole special is how it combines comfort food with a lighter twist. You’ve got tender chicken, fluffy cauliflower rice, and vibrant broccoli all coated in melted cheese. It’s indulgent but still fits perfectly into a low-carb lifestyle.

And did I mention how easy it is? Everything comes together in one dish with minimal prep and cleanup.

1 (16-ounce) bag frozen broccoli florets

Instructions

Preheat the oven to 400°F (200°C). Grease a 3-quart casserole dish with olive oil or nonstick spray.
Prepare the chicken: Slice each breast horizontally to make thinner cutlets. Rub with olive oil, season generously with salt and pepper, and bake for 20 minutes.
Cook the veggies: While the chicken bakes, heat the cauliflower rice and broccoli according to the package directions. Drain any extra moisture.
Chop the chicken: Let it cool slightly, then cut into bite-sized pieces.
Mix it all together: In a large bowl, combine the cooked chicken, cauliflower rice, broccoli, whisked eggs, mozzarella, butter, salt, garlic powder, and onion powder. Stir until everything is evenly coated.
Assemble the casserole: Spread the mixture into the prepared dish and sprinkle the Italian blend cheese evenly over the top.
Bake: Place in the oven and bake for 45–50 minutes, until the cheese is melted, bubbly, and slightly golden.
Cool and serve: Let it rest for about 10 minutes before serving.

Notes

Want extra creaminess? Stir in ½ cup of sour cream or cream cheese before baking.
Use rotisserie chicken to save time on cooking.
You can freeze leftovers in airtight containers for up to 3 months — just reheat in the oven until warmed through.
Add a sprinkle of crushed red pepper flakes for a little heat.
