Spoonful of Mexican cornbread casserole.

I don’t know what y’all had for supper last night but this easy-to-make Mexican cornbread casserole (known around these parts as canyon casserole) is what we had. I barely had to wash the dish when we were done because my brood scraped it clean! Usually, an 8×8 casserole is enough for the four of us. But I’m going to have to double this casserole recipe next time because while my husband and son ate their fill at supper, they both asked me later in the evening if any was left.

I love suppers like that, don’t you? The beauty of this recipe is that it is pretty economical, a meal in one, and packed with a wonderful southwestern flavor. Our casserole includes ground beef, taco seasoning, chopped tomatoes, and corn. We cook those ingredients together before adding them to the casserole dish. Then we mix our cornbread batter with cheese and add that on top. The only thing left to do is bake the casserole for 30 minutes.

Easy casserole recipes like this taco cornbread casserole are the best weeknight supper ideas. I just can’t get enough of the combination of taco-flavored ground beef with the fluffy and flavorful cornbread topping. As you can see, neither can my family! But this casserole is so quick and easy to make that I’m happy to prepare it every week!

  1. I’m going to toss in some retried beans as a layer and maybe finely diced red peppers.

  2. This is the same as my Tamale Pie recipe except it calls for Rotel instead of diced tomatoes. Also, for cornbread topping, I use the envelope of Martha White cornmeal mix … makes the topping so quick and easy.
