Ingredients

This recipe uses simple pantry staples to create something special. Using good quality ingredients—especially the cheese—can make a huge difference.

The Main Players:

• 4 boneless, skinless chicken breasts
• 8 ounces Nacho Cheese Doritos, crushed
• 1 can (15 ounces) of black beans, drained and rinsed¹
• 2 small cans (10.5 ounces each) of Cream of Chicken soup
• 1 can (10 ounces) of Rotel (diced tomatoes and green chilis)²
• ¾ cup of whole milk
• 1 cup of shredded Cheddar Cheese

Don’t Have Something? No Problem.

One of my favorite things about this recipe is how flexible it is. Feel free to swap things out based on what you have on hand.

• Chicken: No raw chicken? Use a pre-cooked rotisserie chicken instead. You can also use cooked ground beef or turkey.
• Doritos: Nacho Cheese is the classic, but Cool Ranch or Spicy Sweet Chili would work great too. Crushed tortilla chips or Fritos are also good options.
• Cream of Chicken Soup: Swap it with cream of mushroom or cream of celery soup. The flavor will be a little different, but still delicious.
• Rotel: A can of diced tomatoes mixed with a can of diced green chiles works just as well. Or, use your favorite jar of salsa for more flavor.
• Cheese: I love using a good block of Cheddar and shredding it myself. Pre-shredded cheese doesn’t melt as well. You can also use a Mexican cheese blend, Monterey Jack, or Pepper Jack cheese.

Step-by-Step Method

Let’s get cooking! I’ll walk you through the process, step by step.

Stage 1: Prep and Preheat

First, preheat your oven to 400°F. While it’s heating up, get your chicken ready.

Place the chicken breasts in a baking dish and put them in the oven for about 20-25 minutes. They’re done when they’re no longer pink inside.

Pro Tip: Use a meat thermometer to be sure. The internal temperature should be 165°F. This makes sure the chicken is cooked perfectly without drying out.

Stage 2: The Flavor Foundation

While the chicken bakes, let’s work on the base.

Take half of your bag of Doritos. Here’s a little secret: you don’t want to crush them into a fine powder. For that perfect crunch, you want them in nice, bite-sized pieces. Just press on the bag gently with your hands or a rolling pin.

Once they’re crushed, spread them evenly across the bottom of your baking dish.

Next, in a separate bowl, mix the Cream of Chicken soup with the milk. Stir until it’s smooth and creamy. This is the glue that will hold everything together.

Stage 3: The Assembly Line

Now that the chicken is cooked, it’s time to build this masterpiece.

Use a fork to shred the chicken. It should fall apart easily.

Mix the shredded chicken with the drained black beans and the Rotel. This adds a zesty, colorful, and hearty element to your casserole.

Next, spread this chicken and bean mixture over the layer of crushed Doritos in your baking dish. Then, pour the creamy soup mixture on top.

Finish with a generous sprinkle of Cheddar cheese for that gooey top.

Avoid This Common Mistake: When spreading the chicken mixture, drop it in spoonfuls instead of dragging it with a spoon. This keeps you from pulling up the Doritos from the bottom.

Stage 4: The Final Layers & Bake

Now, we’ll repeat the layers one more time.

Add a second layer of crushed Doritos, followed by the rest of the chicken mixture, more of the soup, and of course, the rest of the cheese.

Pop the baking dish back into the oven.

Let it bake for another 20-25 minutes. You’ll know it’s done when the cheese is bubbly and golden brown. You’ll also be able to smell it from the other room—and it’ll be amazing.

Mix It Up!

This casserole is your canvas. Feel free to adjust it to suit your tastes or dietary needs.

• Spice Level: For a spicier kick, use hot Rotel or add a tablespoon of taco seasoning. For a milder version, use mild Rotel or regular diced tomatoes.
• Dietary Needs:
  • Gluten-Free: All the main ingredients are naturally gluten-free. Just check your labels to be sure.
  • Dairy-Free: Use a dairy-free cream of mushroom soup and a plant-based shredded cheese.
  • Vegan/Vegetarian: Swap the chicken for black beans, lentils, or a plant-based chicken alternative. Instead of Cream of Chicken soup, use a dairy-free cream of mushroom or celery soup.
• Seasonal Changes: In the summer, add fresh corn. In the winter, try adding some spicy chili powder for a warming kick.
