Instructions

Step 1

Preheat your oven to 375°F (190°C). While the oven is heating, lightly grease a 9×13-inch baking dish with cooking spray or a thin layer of olive oil. This prevents sticking and makes cleanup easier. If you haven’t already cooked your chicken, now is the time: season two boneless skinless chicken breasts with salt, pepper, and a pinch of cumin, then bake at 375°F for 20-25 minutes until the internal temperature reaches 165°F. Let them rest for 5 minutes, then shred using two forks. Alternatively, you can use leftover rotisserie chicken to save even more time.

Step 2

In a large mixing bowl, combine the cooked rice, shredded chicken, drained black beans, drained pinto beans, salsa, Greek yogurt (if using), chili powder, cumin, garlic powder, and half of the chopped cilantro. Stir everything together until well incorporated. The Greek yogurt adds a subtle tang and creamy texture while boosting the protein content. Taste the mixture and adjust salt and pepper as needed. The salsa provides moisture and flavor, so choose your favorite brand or homemade version—mild, medium, or hot depending on your heat tolerance.

Step 3

Transfer the mixture to the prepared baking dish and spread it evenly with a spatula. Sprinkle the shredded Mexican blend cheese over the top in an even layer. The cheese will melt into a golden, bubbly crust that seals in the flavors. For an extra crispy top, you can add a light sprinkle of paprika or chili powder over the cheese.

Step 4

Bake the casserole uncovered for 20 minutes, or until the cheese is fully melted and the edges are bubbling. If you prefer a deeper golden-brown top, switch the oven to broil for the last 2-3 minutes, watching closely to prevent burning. The casserole should be hot throughout—if you inserted a thermometer into the center, it should read at least 165°F.

Step 5

Remove the casserole from the oven and let it rest for 5 minutes. This resting period allows the layers to set, making it easier to slice and serve. Garnish with the remaining fresh cilantro and optional toppings like diced avocado, a dollop of Greek yogurt, or a squeeze of lime juice. Serve warm and enjoy!

For best results

  • For the most tender shredded chicken, cook the breasts in a slow cooker with a little chicken broth on low for 4-6 hours. The meat will be incredibly moist and easy to shred. If you're short on time, purchase a pre-cooked rotisserie chicken from the grocery store—just remove the skin and shred the meat. This cuts prep time by about 15 minutes.
  • To prevent the casserole from becoming watery, make sure to drain and rinse the canned beans thoroughly. The rinsing removes excess sodium and starch, which can otherwise make the dish gummy. Also, if using freshly cooked rice, let it cool slightly before mixing so it doesn't steam the other ingredients.
  • For a lower-carb version, replace the rice with cauliflower rice. Riced cauliflower should be pre-cooked and squeezed dry to remove excess moisture. You can find frozen cauliflower rice in most grocery stores; thaw and press it in a clean kitchen towel before using. This swap reduces carbohydrates by about 30g per serving while keeping the texture satisfying.
  • This casserole freezes exceptionally well. Assemble the dish without the cheese topping, cover tightly with foil, and freeze for up to 3 months. When ready to bake, thaw overnight in the refrigerator, add the cheese, and bake as directed. You can also freeze individual portions in airtight containers for quick grab-and-go lunches.
  • If you're meal prepping for the week, divide the baked casserole into individual containers with a side of fresh vegetables or a simple salad. The flavors actually deepen after a day in the fridge, making it taste even better on day two. Reheat in the microwave for 2 minutes or in a 350°F oven for 10 minutes.

Variations

  • Vegetarian Burrito Bake: Omit the chicken and double the beans—use a mix of black, pinto, and kidney beans for variety. Add a cup of corn kernels (frozen or canned) and a diced bell pepper for extra crunch and sweetness. You can also stir in 8 oz of crumbled queso fresco or cotija cheese for a creamy, tangy flavor. The protein content will be slightly lower, but still satisfying.
  • Spicy Southwest Version: Kick up the heat by using hot salsa, adding 1-2 diced jalapeños (seeds removed for milder heat, or keep them for fire), and mixing in a teaspoon of chipotle powder or adobo sauce from a can of chipotle peppers. Top with pepper jack cheese instead of Mexican blend for an extra layer of spice. Serve with cooling sour cream or avocado.
  • Low-Fat Option: Use fat-free Greek yogurt in place of full-fat, and opt for reduced-fat cheese or simply reduce the cheese amount to 1/2 cup. You can also skip the cheese entirely and top with a sprinkle of nutritional yeast for a cheesy flavor without the fat. This variation cuts about 100 calories and 8g of fat per serving while maintaining high protein.
  • Protein Boost: Add an extra 8 oz of cooked ground turkey or lean ground beef to the mixture for an even higher protein content. You can also stir in a scoop of unflavored protein powder (whey or plant-based) dissolved in a little water before baking—though this may slightly alter the texture. For a vegetarian protein boost, add 1 cup of cooked lentils or edamame.

Common Questions

Can I use brown rice instead of white rice?
Absolutely! Brown rice adds more fiber and a nuttier flavor, making the casserole even more nutritious. Keep in mind that brown rice takes longer to cook, so you’ll need to prepare it ahead of time. Use 2 cups of cooked brown rice, and you may need to add a splash of chicken broth or water to the casserole if it seems dry, as brown rice absorbs more moisture.
How should I store leftovers and how long do they last?
Store any leftover burrito bake in an airtight container in the refrigerator for up to 4 days. To reheat, microwave individual portions for 2-3 minutes, stirring halfway through, or reheat in a 350°F oven for about 10 minutes. You can also freeze the casserole for up to 3 months; thaw overnight in the fridge before reheating.
Can I make this dairy-free?
Yes, simply omit the cheese and Greek yogurt, or use dairy-free alternatives. For the cheese, choose a vegan shredded cheese that melts well, such as those made from cashews or coconut oil. For the yogurt, use a plain unsweetened coconut or almond milk yogurt. The casserole will still be flavorful and creamy, especially if you add a little extra salsa.
Is this recipe gluten-free?
Yes, all the ingredients listed are naturally gluten-free. However, be sure to check the labels on your salsa and canned beans, as some brands may add flour or other gluten-containing ingredients. Most salsas are gluten-free, but it’s always good to verify. Serve with corn tortillas or tortilla chips if desired, but the casserole itself is safe for a gluten-free diet.
Can I prep this casserole in advance and bake later?
Definitely! Assemble the casserole completely (including the cheese topping) and cover it tightly with plastic wrap or foil. Refrigerate for up to 24 hours before baking. When ready to bake, remove the cover and bake as directed, adding an extra 5-10 minutes to the cooking time since the dish will be cold. You can also freeze the unbaked casserole for up to 3 months; thaw overnight in the fridge before baking.
