High Protein BBQ Chicken Casserole - Easy, Satisfying, and Meal-Prep Friendly
Ingredients
Method
- Preheat and prep: Heat the oven to 375°F (190°C). Lightly coat a 9x13-inch baking dish with nonstick spray.
- Cook the chicken (if not using rotisserie): Season chicken breasts with salt, pepper, and a pinch of smoked paprika. Sear in 1 tablespoon olive oil over medium heat for 3–4 minutes per side, then cover and cook until done, or bake at 375°F until the internal temp hits 165°F. Let cool slightly, then shred or dice.
- Mix the sauce base: In a large bowl, whisk together BBQ sauce, Greek yogurt, egg whites (if using), smoked paprika, chili powder, garlic powder, onion powder, 1/2 teaspoon salt, and black pepper. The mixture should be creamy and pourable.
- Add the fillings: Fold in shredded chicken, black beans, corn, bell peppers, red onion, and cooked brown rice or cauliflower rice. Stir until everything is evenly coated. Taste and adjust seasoning.
- Layer and top: Spread the mixture into the baking dish, smoothing it into an even layer. Sprinkle cheese evenly over the top.
- Bake: Bake uncovered for 22–28 minutes, or until the casserole is bubbling at the edges and the cheese is melted and lightly golden.
- Rest and garnish: Let the casserole rest for 5–10 minutes to set. Top with chopped cilantro or green onions if you like. Slice and serve warm.
Why This Recipe Works
This casserole leans on a few smart swaps to boost protein without sacrificing flavor. Chicken breast keeps it lean but satisfying, while black beans and Greek yogurt add extra protein and creaminess. A mix of smoky BBQ sauce and spices brings that classic backyard taste, and roasting everything together lets the flavors meld.
It’s also forgiving: use store-bought rotisserie chicken, frozen veggies, or pre-cooked rice to make it even faster. The result is a balanced, family-friendly dish with a sturdy texture and bold flavor.

How to Store
Cool the casserole to room temperature, then store portions in airtight containers for up to 4 days in the fridge. For freezing, wrap tightly or pack in freezer-safe containers and freeze for up to 3 months.
Reheat individual portions in the microwave (2–3 minutes, stirring halfway) or warm a larger portion in a 325°F oven until hot. If it looks dry after reheating, add a spoonful of BBQ sauce or a dollop of Greek yogurt to bring back moisture.
Benefits of This Recipe
- High in protein: Chicken, Greek yogurt, beans, and optional egg whites stack up the protein to keep you full.
- Balanced macros: Carbs from beans and rice fuel your day; fiber from veggies supports digestion.
- Meal-prep friendly: Makes 6–8 hearty servings that store and reheat well.
- Customizable: Works with different veggies, grains, and sauces based on what you have.
- Family-approved flavors: BBQ, cheese, and tender chicken hit a comfort-food sweet spot without being heavy.
Pitfalls to Watch Out For
- Watery casserole: If using canned corn or freshly cooked cauliflower rice, drain well and pat dry to avoid excess moisture.
- Overcooked chicken: Dry chicken ruins the texture. Cook chicken just to 165°F, then shred.
- Too sweet or too tangy: BBQ sauces vary.
Taste the sauce mix before adding fillings and adjust with a pinch of salt, a squeeze of lemon, or a dash of hot sauce.
- Gummy rice: Use day-old or well-cooled rice for better texture, or go with cauliflower rice if you prefer lower carbs.
- Flat flavor: Don’t skip the spices and salt. The casserole needs seasoning to shine through the creamy base.
Variations You Can Try
- Lower carb: Swap all the rice for cauliflower rice and add extra peppers or zucchini.
- Extra heat: Stir in chipotle peppers in adobo or your favorite hot sauce to the BBQ-yogurt mix.
- Tex-Mex twist: Use pepper jack cheese, add cumin, and garnish with avocado and lime.
- Smoky bacon: Crumble 2–3 slices of cooked turkey bacon over the top before baking for added crunch and smoke.
- Different protein: Try shredded turkey or lean ground chicken. For a pescatarian spin, use shredded cooked salmon and a tangier BBQ sauce.
- Dairy-free: Swap Greek yogurt for a thick dairy-free yogurt and use a dairy-free shredded cheese.
- Sweet potato base: Replace rice with 3 cups roasted diced sweet potatoes for a cozy, slightly sweet finish.

How much protein is in a serving?
It depends on your exact ingredients, but a typical serving (1/8 of the pan) made with chicken breast, Greek yogurt, black beans, and reduced-fat cheddar lands around 30–40 grams of protein.
Using egg whites and extra chicken can push it higher.
Can I make it ahead?
Yes. Assemble the casserole up to 24 hours in advance, cover, and refrigerate. When you’re ready to bake, uncover and bake as directed, adding 5–10 minutes if it’s going in cold.
What BBQ sauce should I use?
Pick a sauce you enjoy on its own.
For a less sweet profile, choose a low-sugar or vinegar-based sauce. For classic flavor, go with a smoky, slightly sweet Kansas City–style sauce. Taste and adjust seasoning to balance sweetness and tang.
Do I need egg whites?
No.
They add a little extra protein and help bind the casserole, but the recipe works fine without them. If you skip egg whites, keep the rest of the ratios the same.
Can I use quinoa instead of rice?
Absolutely. Use 3 cups cooked quinoa.
It keeps the casserole high protein and adds a pleasant, slightly nutty bite.
How do I keep the cheese from getting greasy?
Use a good-quality cheese and avoid overbaking. Reduced-fat cheddar works well here. Bake until just melted and lightly golden for the best texture.
Is this recipe spicy?
As written, it’s mild.
To make it spicier, add chili flakes, diced jalapeño, or a spoon of chipotle in adobo to the sauce mix.
