This budget-friendly chicken burrito casserole is a high-protein, low-cost meal perfect for feeding a family on a tight budget. Easy to make with pantry staples.

Ingredients

• 2 cups cooked shredded chicken (from rotisserie or leftover)
• 1 cup uncooked long-grain white rice
• 1 (15 oz) can black beans, drained and rinsed
• 1 (15 oz) can pinto beans, drained and rinsed
• 1 (10 oz) can diced tomatoes with green chilies (Rotel)
• 1 (4 oz) can diced green chilies
• 1 cup frozen corn kernels
• 1 cup sour cream
• 2 cups shredded Mexican blend cheese
• 1 packet (1 oz) taco seasoning
• 2 cups chicken broth
• 1 tablespoon olive oil
• 1 medium onion, diced
• 3 cloves garlic, minced
• Salt and pepper to taste
• Optional toppings: chopped cilantro, sliced green onions, diced avocado, salsa, hot sauce

Instructions

Step 1

Preheat your oven to 375°F (190°C). While the oven heats, gather all your ingredients. This step ensures everything is at hand and you can work efficiently. Using a rotisserie chicken saves time and adds flavor; if using raw chicken, poach it in seasoned water until cooked through, then shred. Rinsing the canned beans removes excess sodium and improves texture. Drain the corn if using canned instead of frozen.

Step 2

In a large skillet over medium heat, add the olive oil. Once shimmering, add the diced onion and cook for 4-5 minutes until translucent, stirring occasionally. Add the minced garlic and cook for another 30 seconds until fragrant. This builds a savory base for the casserole. Do not let the garlic brown, as it can become bitter.

Step 3

Add the uncooked rice to the skillet and stir for 1 minute to lightly toast the grains. Toasting enhances the nutty flavor and helps the rice stay separate during baking. Then pour in the chicken broth, diced tomatoes with green chilies, diced green chilies, and taco seasoning. Stir well to combine, scraping up any browned bits from the bottom of the pan.

Step 4

Bring the mixture to a gentle boil, then reduce heat to low and simmer for 5 minutes. The rice will begin to absorb liquid but will not be fully cooked. This par-cooking step ensures the rice finishes perfectly in the oven without becoming mushy. Remove from heat.

Step 5

In a large bowl, combine the shredded chicken, black beans, pinto beans, frozen corn, and sour cream. Mix well. The sour cream adds creaminess and tang, balancing the spices. If you prefer a lighter version, you can substitute Greek yogurt.

Step 6

Lightly grease a 9×13-inch baking dish with cooking spray or a thin layer of oil. Spread half of the rice mixture evenly over the bottom of the dish. Then layer half of the chicken-bean mixture on top. Sprinkle with 1 cup of shredded cheese. Repeat the layers with the remaining rice, chicken-bean mixture, and top with the remaining 1 cup of cheese.

Step 7

Cover the baking dish tightly with aluminum foil. Bake for 25 minutes. The foil traps steam, cooking the rice through and melding the flavors. After 25 minutes, remove the foil and bake for an additional 5-10 minutes until the cheese is bubbly and lightly golden. Let the casserole rest for 5 minutes before serving. Resting allows the casserole to set, making it easier to scoop.

Step 8

Serve hot garnished with optional toppings like chopped cilantro, sliced green onions, diced avocado, salsa, or hot sauce. This casserole is a complete meal on its own, but pairs wonderfully with a simple green salad or tortilla chips. Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave or reheat the entire dish in a 350°F oven until warmed through.

For best results

• Use leftover or rotisserie chicken to save time and money. Rotisserie chickens are often cheaper than raw whole chickens and add great flavor. Simply remove the skin and bones, then shred the meat. You can also use canned chicken in a pinch, but drain it well and adjust salt since canned chicken is already seasoned.
• For the best texture, do not skip rinsing the canned beans. The starchy liquid can make the casserole gummy. Rinsing also reduces sodium. If you prefer dried beans, cook them from scratch—it's even more budget-friendly. Use 1.5 cups cooked beans per can.
• To make this casserole even more affordable, use store-brand ingredients. Generic canned tomatoes, beans, and cheese often taste identical to name brands but cost less. Buy rice in bulk and freeze leftover portions of the casserole for quick future meals.
• If you want a spicier kick, add a diced jalapeño with the onion or use hot Rotel. For a milder version, use mild diced tomatoes and omit the green chilies. You can also stir in a teaspoon of cumin or chili powder for extra depth.
• This casserole freezes beautifully. Assemble the casserole completely but do not bake. Cover tightly with foil and freeze for up to 3 months. To bake from frozen, add 20-30 minutes to the covered baking time, then uncover and bake until bubbly. Thaw overnight in the refrigerator for best results.

Variations

• Vegetarian Version: Omit the chicken and double the beans—use black beans, pinto beans, and kidney beans. Add a can of drained and rinsed chickpeas for extra protein. You can also stir in sautéed bell peppers and zucchini for more vegetables. Use vegetable broth instead of chicken broth. The casserole will still be hearty and satisfying.
• Beef Burrito Casserole: Substitute ground beef or turkey for the shredded chicken. Brown 1 pound of ground meat with the onion and garlic, drain excess fat, then proceed with the recipe. The beef adds a richer flavor. For a lower-fat option, use lean ground turkey or chicken.
• Green Chile Chicken Casserole: Use a can of green enchilada sauce instead of the diced tomatoes with green chilies. Add a can of green chiles and use Monterey Jack cheese instead of Mexican blend. This variation has a tangy, slightly spicy flavor reminiscent of green chile enchiladas.
