Ingredients You Need
- 1 tablespoon olive oil or avocado oil
- 1 small yellow onion, diced
- 2 cloves garlic, minced
- 20 ounces cauliflower rice (two 10-ounce frozen bags work great; thaw and squeeze dry)
- 3 cups cooked chicken, shredded or diced (rotisserie chicken saves time)
- 1 cup plain Greek yogurt or sour cream
- 4 ounces light cream cheese, softened
- 1/2 cup low sodium chicken broth
- 1 teaspoon smoked paprika
- 1 teaspoon dried thyme or Italian seasoning
- 1/2 teaspoon onion powder
- 1/2 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon black pepper
- 1 cup shredded sharp cheddar, divided (Tillamook or Cabot melt smoothly)
- 1/3 cup grated Parmesan, divided
- 1 cup chopped spinach or broccoli florets, lightly steamed (frozen spinach works if you thaw and squeeze)
- Optional crunchy topping: 1/2 cup crushed pork rinds or 1/3 cup almond flour mixed with 1 tablespoon melted butter
- Fresh parsley or chives for garnish
Notes and swaps:
- Dairy-free option: use unsweetened plain coconut yogurt and 1/2 cup dairy-free shredded cheese.
- Extra veg: add diced bell pepper or mushrooms and sauté with the onion.
- Heat lovers: add 1 to 2 teaspoons hot sauce or 1/2 teaspoon red pepper flakes.
Equipment
- 12-inch oven-safe skillet or a 9×13 baking dish
- Large sauté pan if not using an oven-safe skillet
- Mixing bowl and whisk
- Spatula and measuring cups
- Paper towels or clean kitchen towel to squeeze moisture from cauliflower rice
Quick Tips & substitutions
- Squeeze thawed cauliflower rice very well so the casserole bakes creamy, not watery.
- Use rotisserie chicken to cut cook time by 15 minutes.
- Swap Greek yogurt with sour cream for a richer sauce.
- Shred cheese from a block for the best melt and fewer additives.
- Short on time: skip the crunchy topping and add extra cheese on top.
- Want more veggies: fold in roasted broccoli or zucchini that you pat dry.
- Salt to taste after you add cheese, since cheese brings salt too.
- Meal prep: assemble in the morning, cover, and bake at dinner.
How to Make Healthy Chicken Cauliflower Rice Casserole Recipe
Step 1: Heat the oven
- Preheat the oven to 400°F. Grease a 12-inch oven-safe skillet or a 9×13 baking dish.
Step 2: Sauté the aromatics and dry out the cauliflower rice
- Heat oil over medium. Add onion and cook 3 to 4 minutes until it softens and smells sweet.
- Stir in garlic for 30 seconds. Add cauliflower rice and cook 8 to 10 minutes, stirring often, until steam slows and the rice dries out.
Step 3: Mix the creamy sauce
- In a bowl, whisk yogurt, cream cheese, and broth until smooth.
- Season with smoked paprika, thyme, onion powder, salt, and pepper.
Step 4: Combine everything
- Add chicken and spinach to the skillet with the cauliflower rice.
- Pour in the sauce, then fold in 1/2 cup cheddar and 2 tablespoons Parmesan. Taste and adjust salt.
Step 5: Top it off
- Smooth the mixture in the skillet or transfer to the baking dish.
- Sprinkle the remaining cheddar and Parmesan on top. Add the crunchy topping if you want it.
Step 6: Bake
- Bake 15 to 20 minutes until the edges bubble and the top turns golden in spots.
Step 7: Rest and serve
- Let the casserole rest 5 to 10 minutes so the sauce thickens.
- Garnish with parsley or chives and serve warm.
Option: Cook the chicken if using raw
- Cut chicken into small bite-size pieces, season with salt and pepper, and sauté with 1 teaspoon oil over medium-high for 4 to 6 minutes until cooked through. Then proceed with Step 4.
Variations
- Buffalo chicken: swap paprika for 2 tablespoons hot sauce and top with blue cheese crumbles.
- Broccoli cheddar: use 2 cups small broccoli florets and sharp cheddar only.
- Tex-Mex: add 1 teaspoon chili powder, 1/2 teaspoon cumin, and 1 cup pepper jack. Top with cilantro.
- Pesto and mozzarella: stir 2 tablespoons basil pesto into the sauce and use mozzarella.
- Dairy-free: use coconut yogurt and dairy-free shreds, then add 1 tablespoon nutritional yeast.
- Extra protein: add 1 cup cottage cheese blended into the sauce for a silky boost.
Ways to Serve
- Pair with a crisp green salad and lemon vinaigrette.
- Serve with roasted green beans or asparagus.
- Add a side of tomato cucumber salad for freshness.
- Top with sliced avocado and a few pickled jalapeños for kick.
- Drizzle with hot sauce if you want heat.
Storage
Cool leftovers, then store them in airtight containers in the fridge for up to 4 days. Freeze portions for 2 to 3 months, and press plastic wrap directly on the surface before sealing to prevent ice crystals. Reheat covered at 350°F for 15 to 20 minutes or microwave in short bursts, stirring between intervals. For the best texture, cook moisture out of the cauliflower rice during the first sauté so reheating stays creamy, not watery.
