Essential Tools for Success
Before you start, make sure you have the following tools handy:

Build Easy Mexican Casserole Step by Step

Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This ensures your casserole bakes evenly and comes out perfectly bubbly and golden.
Step 2: Brown the Ground Beef
In a large skillet over medium heat, add the ground beef. Cook it until it’s browned, breaking it up with a spatula as it cooks. This should take about 5-7 minutes.
Step 3: Season Your Beef
Once the beef is browned, drain any excess fat. Then, sprinkle in the salt, pepper, garlic powder, cumin, and chili powder. Stir to combine, allowing the spices to coat the meat evenly.
Step 4: Add the Sauces and Beans
Next, pour in the tomato sauce and salsa, stirring well to combine all the flavors. Add the drained Great Northern beans and mix gently until everything is evenly distributed.
Step 5: Layer the Casserole
Transfer the beef mixture to the prepared baking dish. Spread it out evenly, and then top it with shredded cheddar cheese. If you love a little crunch, sprinkle crushed corn chips on top.
Step 6: Bake to Perfection
Place the casserole in the preheated oven and bake for 25-30 minutes, or until the cheese is melted and bubbly. The edges should be slightly golden, indicating it’s ready to come out.
Step 7: Serve and Enjoy
Once out of the oven, let the casserole sit for a few minutes before serving. This allows the flavors to meld and makes it easier to scoop. Serve it warm, and enjoy the deliciousness!
Fit It to Your Goals

This Easy Mexican Casserole is incredibly versatile, and you can easily adapt it to fit your dietary preferences:
- Make it vegetarian: Substitute the ground beef with lentils or quinoa for a meatless option.
- Spice it up: Add diced jalapeños or hot sauce for an extra kick.
- Lower the calories: Use ground turkey or chicken instead of beef, and opt for low-fat cheese.
- Add veggies: Toss in some chopped bell peppers, corn, or zucchini for a nutritional boost.
Things That Go Wrong
Even the best cooks encounter hiccups in the kitchen. Here are a few things that can go wrong when making Easy Mexican Casserole, along with tips to avoid them:
- Too watery: If your mixture is too watery, let it simmer a little longer before baking. This will help thicken it up.
- Burnt edges: If you notice the edges browning too quickly, cover the casserole with aluminum foil halfway through baking.
- Uneven cooking: Make sure to spread the beef mixture evenly in the baking dish to ensure even cooking.
- Too dry: If you accidentally overbake it, consider adding a little salsa or sour cream on top when serving to add moisture.
