How to Make It
- Brown the Meat:
- In a large skillet cook the ground beef over medium high heat until deep brown and crumbly. Make sure to break up any large chunks and drain off as much excess fat as possible for a lighter casserole.
- Sauté the Aromatics:
- Add diced onion to the beef in the skillet and stir. Keep the heat at medium to avoid scorching. Wait about three minutes for the onion to soften and start turning translucent then add minced garlic. Stir constantly for a minute so the garlic perfumes the mix but does not brown.
- Mix in Seasonings and Tomatoes:
- Sprinkle the taco seasoning mix over everything and toss thoroughly so every bit of beef and onion is coated. Cook this for a full minute to wake up the spices. Next pour in the entire can of diced tomatoes with green chilies juice and all. Mix until everything is evenly distributed then remove the skillet from heat.
- Build the Casserole Layers:
- Spray your slow cooker insert with nonstick spray. Scatter a layer of tortilla strips across the bottom followed by a scoop of the beef mixture. Add spoonfuls of black beans corn and salsa. Repeat the layers ending with extra tortilla strips a good sprinkle of cheese and a final ladleful of salsa for moisture.
- Cook Slow and Low:
- Cover the slow cooker and set to low for four hours or high for about two hours. Everything should end up bubbly and melty but let it go longer for deeper melding or if your slow cooker tends to run cool.
- Finish with Cheese and Rest:
- Sprinkle remaining cheese on top for the last fifteen minutes of cook time so it melts smoothly. Turn off the slow cooker and let the casserole rest open for at least ten minutes before serving so slices hold their shape.
I never skip adding plenty of garlic since its fragrance is one of my favorite parts of this casserole. Every birthday or game night I think of making it because it guarantees there will be smiles around our table.
Flavor Boosters
Ground turkey or shredded rotisserie chicken work well instead of beef. Pinto beans substitute smoothly for black beans. Monterey Jack or cheddar cheese give a different cheesy melt. Toasting your tortilla strips before layering adds extra flavor oomph.
Serving Suggestions
Top with sour cream, avocado, or chopped cilantro for a bright finish. Serve with a crisp salad or Spanish rice to round out the meal. Leftovers can be stuffed in burritos or rolled into enchiladas for variety.
Creative Twists
Add roasted bell peppers or zucchini in summer for extra vegetables. For a winter version, spice up with chipotle powder or extra cheese for stick-to-your-ribs satisfaction. Fresh tomatoes and corn during peak season bring this casserole even more vibrant flavor.
Slow Cooker Taco Casserole is my weeknight hero. Prep ahead for easy family dinners and savor every zesty, cheesy bite.
