Thanks to my cousin Pam for introducing this Easy Mexican casserole with ground beef to my Fall collection of goodness. This is one of those things that I simply could not stop eating.
How To Make Mexican Casserole with Ground Beef

Just grab your favorite frying skillet and heat it over medium high heat.
- Once the skillet is hot, add the ground beef.
- With your favorite spatula, break the ground beef apart.
- Once the pink starts to fade from the meat, add the chopped onions.
- Cook until the onions are starting to soften.
- Add canned black beans (drained)
- Frozen or canned yellow corn (drained if using canned) I prefer frozen corn, 1 cup.
- 2 cans of tomatoes (drained)
- And 8 chile peppers, roasted, peeled, seeded and chopped. Hatch work great here, Pueblo (Mirisol) Peppers are lovely or 2-4 ounce can of chopped chiles (undrained) make this even easier.
- Add taco seasoning and 1/2 to 1 cup of water and let simmer for about 10 – 15 minutes or until mixture starts to thicken. Start with 1/2 cup of water and add more if mixture becomes dry. Here’s why:
- Important Tip: If the mixture is too watery, this will cause the corn tortillas to become soggy during baking. Different taco seasoning mixes may contain different amounts of corn starch (for the thickening agent) This is why I say start with 1/2 cup and add a little more at a time. You want the mixture a little soupy but not watery.
I urge you to use Homemade Taco Seasoning for this. It’s superior in flavor and void of preservatives. Ever since I discovered smoked paprika a few years ago, I’ve gone crazy using it. And sprinkling some in taco seasoning is no exception and adds a wonderful smoky flavor. I hope you take a look at this recipe.
If you’d like substitute this homemade mixture, just use about 3 tablespoons instead of a packet of taco seasoning. It brings a whole new level of earthy depth to this casserole. And you’ll love that bold color and bold flavor.
How to Build This Mexican Casserole with Corn Tortillas

- Spray a 9 x 11 baking dish with PAM
- Add about 1 cup of the beef mixture as evenly as you can on the bottom of your baking dish. It won’t cover the pan, but will add a barrier for the tortillas so they will stay moist during baking.
- Place 6 corn tortillas over the ground beef mixture, overlapping them and placing them so they curl up the side of the dish by about a half inch.

- Cover the corn tortillas with half the remaining beef mixture

- Spread the sour cream over the beef mixture.

- Place the remaining 6 corn tortillas on top of the sour cream in the same manner you did with the first layer.
- Add the remaining ground beef mixture.
- Sprinkle with the cheese.

- Bake the casserole in a 350 degree oven for 25 – 30 minutes.
- Let the casserole sit for about 5 – 10 minutes. Cut into squares and serve. YUM!
