Funky Casserole

This recipe is adapted from Funky Enchilada Casserole on All Recipes. The original author said, “My good friend brought this to me in the hospital after I had just had a baby. My husband promptly took it home and ate the entire thing without sharing. I had to remake it myself to find out what he’d been raving about. I’ve made a few adjustments and so can you according to your tastes! This is a great casserole to make because some of the canned ingredients you may already have. Serve with sour cream, hot sauce, and cold diced tomatoes or salsa if you like. Maybe even serve some chips and guacamole to round it out.” I do have to agree that this dinner is delicious! I loved all the flavors and textures and think this should be added to the rotation, for sure. Enjoy!

Ingredients/Substitution Ideas

  • Olive oil–or canola oil, vegetable oil
  • White corn tortillas–or yellow corn tortillas
  • Boneless skinless chicken breasts–or thighs
  • Kosher salt
  • Garlic powder
  • Black pepper
  • Cumin
  • Chili powder
  • Smoked paprika
  • Onions–yellow, white
  • Green pepper
  • Red pepper
  • Orange pepper–or yellow
  • Chili black beans–Look for them by the other canned beans. I used S&W brand. You can also use chili pinto beans. Bush’s is another good brand.
  • Frozen sweet white corn–or canned corn
  • Pepper jack cheese–or monterey jack
  • Salsa and sour cream–optional but yummy!

Steps

Heat oven to 350° F. Heat a large skillet over medium high heat. Add in 1 Tbsp of the oil and swirl around. Add in the tortillas and heat on each side until light brown bubbles start to form. Place the corn tortillas in a 9×9 inch baking dish and set aside. 

Add the remaining 1 Tbsp of oil into the skillet and add in the chicken. Season with the salt, pepper, cumin, chili powder and smoked paprika.

Cook for about 4 minutes and then add in the onions and peppers and cook for another 4 minutes.

Stir in the beans and corn until combined. Turn off heat. 

Tear the corn tortillas into bite size pieces.

Pour the skillet mixture over the top of the tortillas. Sprinkle the pepper jack cheese on top.

Bake for 25 minutes. Serve with sour cream and salsa.

Notes/Tips

  • Serve with all your favorite toppings such as cilantro, guacamole, sour cream and pico de gallo.
  • I baked this dish in a 9×9 inch glass baking dish*.
  • This recipe can be gluten free. Just make sure to check the chili beans label.
  • Store leftovers in an airtight container* in the refrigerator for up to 4 days or in the freezer for up to 3 months.
  • Other recipes you can make with bell peppers are Instant Pot Chicken Fajita and Rice Soup and Instant Pot Cajun Chicken Pasta.
  • For tender chicken: slice against the grain. Look at the muscle fibers and cut perpendicular to those lines. Slice into ½ inch wide strips. Turn the strips 90° and cut crosswise into ½ inch cubes.
