This Instant Pot enchilada casserole is made with layers of seasoned ground beef, corn tortillas, enchilada sauce, and melty cheese for an easy family-friendly dinner.
In a skillet over medium heat, cook the ground beef until no longer pink. Drain any excess grease, then stir in the taco seasoning until evenly coated.
Spray a 7-inch springform pan with cooking spray. Using 6 tortilla halves (3 whole corn tortillas), layer them on the bottom of the pan, slightly overlapping as needed.
Spread half of the seasoned beef evenly over the tortilla layer, then top with ½ cup enchilada sauce and ½ cup shredded cheese.
Add another layer of tortilla halves (3 whole tortillas cut in half). Repeat with the remaining beef, ½ cup enchilada sauce, and ½ cup cheese. Finish with the final layer of tortillas and top with the remaining ½ cup enchilada sauce. Do not add the last layer of cheese yet.
Spray one side of a piece of foil with cooking spray and lightly cover the springform pan, sprayed side down. Add 1 cup water to the Instant Pot liner and place the trivet inside. Lower the pan onto the trivet, secure the lid, and set the valve to sealed. Cook on manual high pressure for 10 minutes, followed by a quick release. Carefully remove the foil once the pin drops.
Sprinkle the remaining ½ cup shredded cheese evenly on top, then place the Instant Pot lid back on for 3–5 minutes, or until the cheese is melted.
Carefully remove the pan from the Instant Pot using pot holders and place it on a serving tray. Slice, add your favorite toppings, and serve warm.
Notes
Corn tortillas hold up best during pressure cooking, but flour tortillas can be used for a softer texture.
Depending on your Instant Pot model, you may need an extra 3-5 minutes of cook time if the center isn’t fully heated through.
Let the casserole rest for a few minutes before slicing so the layers stay together better.
Top with sour cream, chopped cilantro, avocado, black olives, or green onions before serving for extra flavor.
