What Ingredients are in Southwest Enchilada Casserole?
This Southwest Enchilada Casserole is a hearty, flavor-packed dish that brings together all the best elements of traditional enchiladas in an easy-to-prepare casserole format. Perfect for NuWave Oven or Flavorwave cooking, this recipe combines seasoned ground beef, beans, and cheese wrapped in tortillas and smothered in enchilada sauce. You’ll need just a handful of ingredients to create this satisfying Tex-Mex inspired meal.
- 1½ pounds ground beef
- 1 small onion
- 4 flour tortillas
- 12 ounces olives
- 1 (12 ounce) can refried beans
- 12 ounces enchilada sauce
- 1½ cups cheese
- Seasonings to taste (such as taco seasoning, salt, pepper, cumin, or chili powder)
When shopping for these ingredients, consider your heat preference when selecting enchilada sauce—mild, medium, or hot will all work wonderfully. For the cheese, a Mexican blend or sharp cheddar would be ideal, though you could experiment with pepper jack for extra kick. And while the recipe calls for flour tortillas, corn tortillas can be substituted for a more authentic flavor and gluten-free option. Just be sure they’re fresh, as corn tortillas tend to crack when rolled if they’re too dry.
How to Make this Southwest Enchilada Casserole

Creating this mouthwatering Southwest Enchilada Casserole in your NuWave oven couldn’t be simpler. You’ll start by browning 1½ pounds of ground beef with a small diced onion in a skillet until fully cooked. Make certain to add your favorite seasonings—perhaps some cumin, garlic powder, or chili powder would work beautifully here. Once the meat is browned through, don’t forget to drain off any excess grease, which helps keep your casserole from becoming too oily.
Next comes the fun part: assembly. Take each of your 4 flour tortillas and layer them individually with a generous spread of refried beans (from your 12-ounce can), a portion of your seasoned meat mixture, a spoonful of enchilada sauce (from your 12-ounce can), a few sliced olives (from your 12-ounce package), and a sprinkle of cheese from your 1½ cups. Roll each tortilla tightly and place them seam-side down on the liner pan of your NuWave oven. This prevents them from unraveling during cooking, which would be quite the kitchen disaster, wouldn’t it?
Pour the remaining enchilada sauce over your rolled tortillas, scatter the rest of those tasty olives on top, and cook for about 25-30 minutes. In the final two minutes of cooking, sprinkle the remaining cheese over the top to create that irresistibly gooey, melty finish that makes everyone reach for seconds. The NuWave’s circulating heat guarantees everything cooks evenly, giving you perfectly melted cheese and heated-through enchiladas every time. If you’re looking for even more cooking flexibility, consider using an air fryer convection oven which offers multiple cooking functions in one versatile appliance.
Southwest Enchilada Casserole Substitutions and Variations
The beauty of this Southwest Enchilada Casserole lies in its flexibility—you can easily adapt it to suit your dietary needs or pantry limitations. Don’t have ground beef? Try ground turkey, chicken, or even a plant-based alternative for a lighter version. Vegetarians might swap in extra beans, corn, and sautéed bell peppers.
Need a gluten-free option? Corn tortillas work beautifully in place of flour ones. And the cheese—oh, the possibilities. While the recipe calls for a standard cheddar blend, I’d suggest trying pepper jack for extra heat or a Mexican cheese blend for authenticity.
Can’t find enchilada sauce? A quick homemade version with tomato sauce, chili powder, cumin, and garlic makes a wonderful substitute. Trust me, this dish welcomes creativity.
What to Serve with Southwest Enchilada Casserole
While your Southwest Enchilada Casserole sizzles away in the NuWave oven, you might wonder what sides could possibly complement such a flavor-packed main dish. I’m a firm believer that the perfect accompaniments balance the rich, spicy notes without overwhelming them.
A simple cilantro-lime rice makes an ideal partner, soaking up that extra enchilada sauce like a dream. For something fresh, try a crisp jicama slaw with a touch of lime and chili powder. Can’t forget about a side of cool guacamole or sour cream to tame the heat.
Want to go all out? Serve with Mexican street corn (elotes) or a light cucumber-tomato salad. Trust me, these sides transform your casserole from a mere meal into a fiesta on a plate.
Final Thoughts
After mastering this Southwest Enchilada Casserole in my NuWave oven, I’ve come to appreciate how kitchen gadgets can transform everyday cooking into something special. The way those tortillas roll up with all that savory beef, beans, and melty cheese is just magical, don’t you think?
What I love most about this recipe is its versatility. Having guests who don’t eat meat? Swap in black beans. Need more spice? Add some diced jalapeños to the mix. The NuWave makes it all so simple—no need to heat up your entire kitchen with a conventional oven.
Trust me, this dish will quickly become your go-to for weeknight dinners when you want something that feels special without hours of work. Comfort food with a southwestern twist!
