Ingredients

I love that every ingredient serves a purpose here. The combination creates a creamy, flavorful casserole without relying on rice, tortillas, or other higher-carb ingredients.

Cooked Chicken Breast – 4 cups, shredded

Lean chicken breast provides most of the protein in this recipe. Rotisserie chicken also works if you want to save time.

Cauliflower Rice – 4 cups

Cauliflower rice replaces traditional rice while keeping the casserole hearty and satisfying. It absorbs all the delicious seasonings without adding many carbs.

Plain Greek Yogurt – 1 cup

Greek yogurt creates a creamy texture while adding extra protein. I prefer full-fat or 2% versions for the best flavor.

Shredded Mexican Cheese Blend – 1½ cups

A moderate amount of cheese adds richness and helps bind everything together without making the casserole overly heavy.

Bell Pepper – 1 large, diced

Bell pepper adds color, freshness, and extra nutrients. Red, orange, or yellow peppers all work well.

Yellow Onion – 1 medium, diced

Onion provides savory flavor and sweetness as it cooks.

Black Beans – 1 cup, drained and rinsed

While slightly higher in carbs than other ingredients, they add fiber, protein, and authentic burrito flavor. For even lower carbs, you can reduce or omit them.

Diced Green Chiles – 1 can (4 ounces)

These add mild heat and plenty of flavor without making the dish spicy.

Olive Oil – 1 tablespoon

Used for sautéing the vegetables and enhancing flavor.

Chili Powder – 2 teaspoons

Adds classic burrito-style seasoning.

Ground Cumin – 1 teaspoon

Provides warmth and depth that makes the casserole taste restaurant-worthy.

Garlic Powder – 1 teaspoon

A simple way to boost savory flavor throughout the dish.

Paprika – 1 teaspoon

Adds mild smokiness and color.

Salt – 1 teaspoon

Helps bring all the flavors together.

Black Pepper – ½ teaspoon

Adds subtle heat and balance.

Optional Add-Ins

• Jalapeños for extra heat
• Fresh cilantro
• Diced zucchini
• Corn (if not strictly low-carb)
• Avocado slices for serving
• Fresh lime wedges
• Sliced green onions

Let’s Make It

Save

One reason I enjoy this recipe so much is that it comes together with simple steps. Most of the work happens in one skillet before everything goes into the oven.

Step 1: Prepare the Oven and Dish

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish and set it aside.

Step 2: Cook the Vegetables

Heat 1 tablespoon olive oil in a large skillet over medium heat. Add the diced onion and bell pepper, cooking for about 5 minutes until softened and fragrant.

Step 3: Add the Seasonings

Stir in 2 teaspoons chili powder, 1 teaspoon cumin, 1 teaspoon garlic powder, 1 teaspoon paprika, 1 teaspoon salt, and ½ teaspoon black pepper. Cook for about 30 seconds until the spices become aromatic.

Step 4: Build the Filling

Add 4 cups cauliflower rice, 4 cups shredded chicken, 1 cup black beans, and the can of green chiles. Stir everything together until evenly combined and heated through.

Step 5: Make It Creamy

Remove the skillet from the heat. Fold in 1 cup Greek yogurt and 1 cup shredded cheese. The mixture should look creamy and well combined.

Step 6: Assemble the Casserole

Transfer the mixture to your prepared baking dish. Spread it evenly and sprinkle the remaining ½ cup cheese over the top.

Step 7: Bake Until Golden

Bake for 25 to 30 minutes until the casserole is bubbling around the edges and the cheese is melted and lightly golden.

Step 8: Rest and Serve

Allow the casserole to rest for about 5 minutes before serving. This helps everything set up and makes slicing easier.

The high protein content comes primarily from chicken breast and Greek yogurt. Together they provide sustained energy and help make each serving incredibly satisfying.

Cauliflower rice, bell peppers, onions, and beans contribute fiber, which supports fullness and digestion. The moderate amount of cheese adds healthy fats and flavor without overwhelming the nutritional profile.

Easy Ingredient Swaps

I often adjust this recipe depending on what I have available, and it remains delicious every time.

Instead of Chicken Breast

Cooked turkey breast works extremely well and offers a similar protein content. Lean ground chicken is another excellent option.

Instead of Greek Yogurt

Reduced-fat cream cheese can create a richer casserole. Cottage cheese blended until smooth also works nicely while keeping protein high.

Instead of Black Beans

Extra cauliflower rice or diced zucchini can further reduce carbohydrates while maintaining volume.

Instead of Mexican Cheese Blend

Monterey Jack, cheddar, mozzarella, or pepper jack all melt beautifully in this recipe.

Make-Ahead and Meal Prep Notes

This casserole is perfect for meal prep because it holds its flavor and texture very well over several days.

After baking, allow it to cool slightly and divide it into equal portions for the week. This makes it easy to grab a ready-made lunch or dinner without additional cooking. You can check more high protein lunch ideas here.

Many people find that the flavor actually improves after a day in the refrigerator as the spices blend together more deeply. This makes it one of those rare dishes that tastes even better as leftovers.

It’s especially useful for busy schedules because it removes the need to cook multiple times during the week while still keeping meals healthy and homemade.

Fun Ways to Change It Up

Save

This recipe is highly versatile, making it easy to adjust based on your preferences or dietary needs.

For a spicy version, add diced jalapeños, chipotle powder, or pepper jack cheese to increase the heat level. This gives the casserole a stronger Southwest-style flavor.

For a keto-friendly version, simply remove the black beans and increase the amount of chicken, cheese, or cauliflower rice. This lowers the carbohydrate content even further while keeping it filling.

For a vegetarian version, replace the chicken with extra black beans, chickpeas, tofu, or additional vegetables like mushrooms and zucchini. The spices and sauce still make it very flavorful without meat.

For an extra creamy version, add a few tablespoons of cream cheese along with the Greek yogurt. This creates a richer, more indulgent texture.

Favorite Ways to Serve It

I usually serve this casserole as a complete meal because it already contains protein, vegetables, and healthy fats.

Fresh avocado slices or guacamole add creaminess and healthy fats that complement the savory flavors of the casserole. A simple green salad with a light lime or vinaigrette dressing adds freshness and balance.

Salsa or pico de gallo can bring brightness and acidity, while roasted vegetables add extra volume and nutrients. If you want something extra refreshing, a cucumber and tomato salad pairs especially well with the bold spices.

Flavor Tips and Cooking Tricks

A few small adjustments can take this casserole from great to exceptional.

To deepen the flavor, allow the spices to toast in the pan for about 30 seconds before adding the rest of the ingredients. This helps release their natural oils and makes the dish more aromatic.

Using rotisserie chicken is a great shortcut and adds extra juiciness and flavor. If you prefer a fresher taste, freshly cooked chicken breast works perfectly as well.

Adding a squeeze of fresh lime juice just before serving can brighten the entire dish and balance the richness of the cheese and yogurt. Fresh toppings like cilantro, avocado, or green onions also enhance flavor and texture.

Be careful not to overbake the casserole. It is ready as soon as the cheese is melted, bubbly, and lightly golden on top.

Common Mistakes to Avoid

A few simple mistakes can affect the final texture and flavor of this casserole, so it’s worth keeping these in mind.

Skipping the spice step can lead to a less flavorful dish, so make sure to bloom the spices in the pan before adding other ingredients. This step is key for developing depth of flavor.

Using too much cauliflower rice can make the casserole watery, so stick to the recommended amount for the best texture.

Overbaking can dry out the chicken and make the dish less creamy, so remove it from the oven as soon as the cheese is melted and lightly golden.

Finally, make sure to drain the black beans properly to avoid excess moisture in the casserole.

Keeping Leftovers Fresh

The leftovers are often just as good as the first serving, which is always a bonus.

Refrigerator Storage

Store cooled leftovers in an airtight container for up to 4 days. Individual portions work especially well for grab-and-go lunches.

Freezer Storage

This casserole freezes beautifully. Wrap tightly or store in freezer-safe containers for up to 3 months.

Reheating

Reheat individual portions in the microwave for 1 to 2 minutes. Larger portions can be warmed in a 350°F oven until heated through.

Common Questions

Finely chopped broccoli rice works well and keeps the recipe low-carb.
