Instant Pot Chicken Enchilada Casserole Recipe: Layered Tex-Mex in One Pot

This one-pot wonder brings all the flavors of chicken enchiladas without the fuss of rolling and baking. A foolproof method for busy weeknights, it layers tortillas, chicken, and cheese right in your Instant Pot for quick, hands-off cooking.

The secret lies in the strategic layering and a well-seasoned sauce that infuses every bite with bold Tex-Mex flavor. In under 30 minutes, you’ll have a meal that tastes like it simmered all day, with tender chicken and perfectly melted cheese.

No oven required—just stack the ingredients, seal the lid, and let the pressure cooker work its magic. The result is a hearty, satisfying casserole with all the textures you crave, from the soft tortillas to the gooey cheese topping.

Serve it straight from the pot, garnished with fresh cilantro or a dollop of sour cream. This is comfort food made simple.

Ingredients for Instant Pot Chicken Enchilada Casserole

Mostly pantry staples plus a few fresh items. Ready in under thirty minutes.

The tortillas are key here—corn tortillas hold up best to the pressure cooking (flour ones can get gummy). Mission or La Banderita brands are solid supermarket picks. For the enchilada sauce, Las Palmas or Rosarita work great straight from the can. I always grab the mild version and bump up the heat with extra chili powder if needed (the good stuff, not the pre-shredded kind).

No corn tortillas? Flour tortillas can work in a pinch, but cut them into strips so they don’t tear. Swap black beans for pinto beans if that’s what you’ve got. The cheeses can be any melty variety—pepper jack for heat, Colby for mildness. Short on time? Rotisserie chicken works perfectly here—just shred about 3 cups worth and skip the raw chicken step.

Leftovers keep beautifully for 4-5 days in the fridge, and the flavors actually deepen. Freeze portions for up to 3 months (just thaw overnight before reheating). Pro tip: cut into individual servings before storing—makes reheating a breeze.

Step-by-Step Instructions for Instant Pot Chicken Enchilada Casserole

Here’s how I make this one-pot wonder without the fuss.

Step 1: Sauté the Aromatics and Season the Chicken

Set your Instant Pot to the sauté function and add the 1 tbsp olive oil. When hot, add the finely diced yellow onion and cook for 3-4 minutes until it turns translucent and just starts to brown.

Add the minced garlic cloves, 1 tbsp chili powder, and 1 tsp ground cumin. Stir constantly for 30 seconds until fragrant—this prevents the spices from burning. Then add the 1.5 lb boneless skinless chicken breasts cut into bite-sized pieces and cook for 2 minutes to sear lightly.

Step 2: Pressure Cook the Chicken and Beans

Pour in the 0.5 cup chicken broth, 1 can diced green chiles, and 1 can black beans (drained and rinsed). Stir to combine, making sure to scrape up any browned bits from the bottom of the pot for maximum flavor.

Secure the lid, set the valve to sealing, and cook on high pressure for 8 minutes. The chicken should be fall-apart tender when done. Once the cooking time is complete, let the pressure release naturally for 5 minutes, then quick-release any remaining pressure.

Step 3: Shred the Chicken and Layer the Casserole

Remove the chicken and shred it using two forks. Return the shredded chicken to the pot and stir in ½ cup red enchilada sauce to coat everything evenly.

Now, start layering: spread 4 pieces corn tortillas in the bottom of the pot, followed by half the chicken mixture. Sprinkle 1 cup shredded cheddar cheese and ½ cup shredded monterey jack cheese on top. Repeat with the remaining 4 pieces corn tortillas, chicken, and the rest of the 2 cups red enchilada sauce.

Step 4: Finish with Cheese and Broil (Optional)

Top the layers with the remaining 1 cup shredded cheddar cheese and ½ cup shredded monterey jack cheese. If your Instant Pot has a broil function, use it for 2-3 minutes to melt and brown the cheese. Otherwise, cover and let the cheese melt from the residual heat.

Let the casserole rest for 5 minutes before serving. This allows everything to set slightly, making it easier to scoop out perfect portions.

Step 5: Garnish and Serve

Sprinkle the top with 0.25 cup fresh cilantro for a pop of color and freshness. Serve with a dollop of 0.5 cup sour cream on the side for those who like a creamy contrast to the bold Tex-Mex flavors.

Each serving should have layers of tender chicken, melty cheese, and soft tortillas soaked in flavorful enchilada sauce. Dig in while it’s hot!
