Why I Love This Recipe
Crockpot casseroles are the kind of dinner I reach for when I want something filling without standing in the kitchen all afternoon. This one has the flavors of chicken enchiladas, but there is no rolling tortillas one by one.
I also love the texture. The tortillas soak up some of the sauce but still give the casserole body. The beans and corn make every scoop hearty, while that melted cheese on top brings everything together.
- Very little prep: Most of the work happens in the crockpot.
- No tortilla rolling: Chop them up and stir them in.
- Big enchilada flavor: Chicken, spices, red sauce, tortillas, and cheese give you the flavors you expect.
- Filling: Chicken and black beans add plenty of protein.
- Easy to change: Add more heat, different cheese, or your favorite toppings.
- Great for leftovers: The flavors are still delicious the next day.
What You’ll Need
- 2 pounds boneless, skinless chicken breasts
- 1 teaspoon chili powder
- 1 teaspoon ground cumin
- ½ teaspoon garlic powder
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 2 cans (10 ounces each) red enchilada sauce, divided
- 1 can (15 ounces) black beans, drained and rinsed
- 1 can (15 ounces) corn, drained
- 10 small corn tortillas, cut into 1-inch pieces
- 2½ cups shredded Mexican-blend cheese, divided
- 2 tablespoons chopped fresh cilantro, for serving
- 2 tablespoons diced red onion, for serving
Recipe and Instructions
Step 1: Season the Chicken
Place 2 pounds boneless, skinless chicken breasts in the bottom of a black oval crockpot. Keep them in a fairly even layer.
Sprinkle the chicken evenly with 1 teaspoon chili powder, 1 teaspoon ground cumin, ½ teaspoon garlic powder, ½ teaspoon salt, and ¼ teaspoon black pepper.
Step 2: Add the Enchilada Sauce
Pour 1½ cans, or 15 ounces, red enchilada sauce evenly over the seasoned chicken. Save the remaining 5 ounces for Step 5.
Cover the crockpot with its lid.
Step 3: Slow Cook the Chicken
Cover and cook on LOW for 4–6 hours or HIGH for 2½–3½ hours.
The chicken is ready when the thickest part reaches 165°F (74°C) and pulls apart easily.
Step 4: Shred the Chicken
Leave the chicken in the crockpot. Use two forks to shred all 2 pounds of cooked chicken directly into the enchilada sauce.
Stir until every piece of chicken is coated with sauce.
Step 5: Build the Casserole
Add the reserved 5 ounces red enchilada sauce, 1 can (15 ounces) drained and rinsed black beans, 1 can (15 ounces) drained corn, 10 small corn tortillas cut into 1-inch pieces, and 1½ cups shredded Mexican-blend cheese.
Gently stir everything together. Try not to mash the beans or stir so much that the tortillas turn to mush.
Step 6: Add the Cheese Topping
Spread the mixture into an even layer.
Sprinkle the remaining 1 cup shredded Mexican-blend cheese evenly over the top.
Put the lid back on and cook on HIGH for 20–30 minutes, or until the cheese is completely melted.
Step 7: Garnish and Serve
Turn off the crockpot and let the casserole sit uncovered for 5–10 minutes. This helps it thicken a little.
Spoon the casserole into a round serving bowl. Top the whole batch with 2 tablespoons chopped fresh cilantro and 2 tablespoons diced red onion, or add them to individual servings.
Why This Recipe Works (Quick Science)
Slow cooking gives the chicken time to become tender. The gentle heat helps the meat cook without needing constant attention.
Corn tortillas contain starch. Once the tortilla pieces are stirred into the hot enchilada mixture, they absorb some of the extra liquid. That helps turn the saucy chicken into a casserole instead of a soup.
Cheese contains both fat and protein. Gentle heat melts it into a soft, creamy topping. Giving the finished casserole 5–10 minutes to rest also lets the sauce settle and thicken before serving.
Pro Tips
- Check the chicken early if your crockpot runs hot. Chicken breast can dry out when cooked much longer than needed.
- Use an instant-read thermometer. Chicken should reach 165°F (74°C) in its thickest part.
- Drain the beans and corn well. Extra liquid can make the casserole watery.
- Cut the tortillas into similar 1-inch pieces so they soften at about the same rate.
- Don’t add the tortillas at the beginning. Adding them after the chicken cooks keeps them from completely disappearing into the sauce.
Tools You’ll Need
- Black oval crockpot, about 6 quarts
- Measuring cups
- Measuring spoons
- Can opener
- Colander
- Cutting board
- Chef’s knife
- Two forks
- Wooden spoon or silicone spatula
- Instant-read meat thermometer
- Serving spoon
- Round serving bowls
Substitutions and Variations
- Chicken thighs: Use boneless, skinless chicken thighs for richer, juicier meat.
- Cheese: Cheddar, Monterey Jack, or Pepper Jack can replace Mexican-blend cheese.
- More heat: Add diced jalapeño or use a hot red enchilada sauce.
- Less heat: Choose a mild enchilada sauce.
- Beans: Pinto beans can replace black beans.
- No corn: Simply leave it out.
- Flour tortillas: They can work, but they become much softer than corn tortillas.
- Extra toppings: Try avocado, sour cream, lime wedges, sliced jalapeños, or extra cilantro.
Common Mistakes
- Adding tortillas too early: They can become very soft and mushy.
- Using undrained corn or beans: The extra liquid can thin the casserole.
- Overcooking the chicken: Start checking it near the early end of the cooking range.
- Using too small a crockpot: A roughly 6-quart crockpot gives the ingredients enough room.
- Skipping the resting time: Five to ten minutes makes the finished casserole easier to scoop.
- Over-stirring: Fold everything together gently after adding the tortillas.
What to Serve With
This casserole is already filling, so simple sides work best.
- Green salad with lime dressing
- Mexican-style rice
- Sliced avocado
- Guacamole
- Pico de gallo
- Roasted vegetables
- Tortilla chips and salsa
- Sour cream
- Fresh lime wedges
Make-Ahead Tips
You can measure the seasonings, drain the beans and corn, shred the cheese, and chop the red onion a day ahead.
Wait to cut and add the corn tortillas until you are ready to finish the casserole. This gives you the best texture.
The chicken can also be cooked and shredded in the enchilada sauce ahead of time. Refrigerate it in a covered container, then reheat it thoroughly before continuing with the beans, corn, tortillas, and cheese.
Macros Information
Approximate nutrition per serving, based on 8 servings:
- Calories: 455
- Protein: 40 g
- Carbohydrates: 38 g
- Fat: 17 g
- Fiber: 7 g
These numbers are estimates. The exact macros will change depending on your enchilada sauce, tortillas, cheese, chicken, and serving size.
Leftovers and Storage
Let leftovers cool, then transfer them to an airtight container.
Keep the casserole in the refrigerator for up to 3–4 days. Reheat individual servings in the microwave until steaming hot throughout.
For longer storage, freeze portions in freezer-safe containers. The casserole can be frozen for about 2–3 months, though the tortillas will be softer after thawing.
Thaw frozen portions overnight in the refrigerator before reheating. A little fresh cheese, cilantro, or diced onion can brighten up reheated leftovers.
FAQ
Q: Can I put raw chicken directly in the crockpot?
A: Yes. This recipe starts with raw boneless, skinless chicken breasts. Cook until the thickest part of the chicken reaches 165°F (74°C).
Q: Can I add the tortillas when I add the raw chicken?
A: I would not. They have several hours to soak up liquid and can become very mushy. Add them after the chicken has cooked and been shredded.
Q: Why is my casserole watery?
A: The beans or corn may not have been drained well, or the casserole may need a short rest. Leave it uncovered for 5–10 minutes before serving.
Q: Can I use green enchilada sauce?
A: Yes. It changes the flavor, but the same amount can be used.
Q: Can I use frozen chicken?
A: For food safety and more even cooking, thaw the chicken in the refrigerator before putting it in the slow cooker.
Q: How do I know when the chicken is done?
A: Check the thickest piece with an instant-read thermometer. It should reach at least 165°F (74°C) and should shred easily.
Q: Can I make this spicier?
A: Yes. Use hot enchilada sauce, Pepper Jack cheese, diced jalapeño, or your favorite hot sauce.
