Jiffy Mexican Cornbread Casserole Recipe
Print Pin Recipe Rate RecipeIngredients
- 1 pound lean ground beef, 90/10
- 1 cup chopped onion
- 1 ounce taco seasoning
- 11 ounces whole kernel corn, drained
- 14.75 ounces cream-style corn
- 10 ounces Rotel tomatoes
- 4 ounces diced green chiles
- salt & pepper to taste
- 8 ounces pepper jack cheese, shredded (2 cups)
- 17 ounces Jiffy corn muffin mix, 2 8.5 ounce boxes
- 2 eggs
- ⅔ cup buttermilk
Instructions
- Preheat your oven to 400°F. Spray a 9x13 casserole dish like you mean it and set it aside. You're about to commit carb-based magic.
- Brown the ground beef in a big skillet. Halfway through, toss in those chopped onions like you're on a cooking show. Cook it all down until there's no pink in sight.
- Drain the grease if there is any. Stir in the taco seasoning, both corns, Rotel, chiles, salt and pepper. Give it a good mix. Let it simmer about 5 minutes so everything gets cozy.
- Pour that meaty goodness into your greased pan, (or leave it in an oven-safe iron skillet) Sprinkle with 1 cup of cheese-generously, like you're trying to impress your in-laws.
- In a bowl, whisk the eggs and buttermilk. Stir in the Jiffy mix until it's just combined.
- Gently spread the cornbread batter over the meat layer. Smooth it out like you're icing a very yellow, very humble cake.
- Bake for 15-20 minutes, or until the top is golden and your kitchen smells like absolute yum.
- Pull it out, sprinkle the remaining cheese on top, pop it back into the oven for 2-5 minutes, and let it melt into a gooey blanket of joy.
- Let stand 5 minutes before serving.
Notes
- Drain smart. Drain the beef well so the casserole doesn't turn into greasy soup. Nobody's here for that. Better yet, make sure you use 90/10 ground beef and you won't have to drain it.
- Let it rest. Give the casserole 10 minutes after baking to firm up. Otherwise, you'll be serving cornbread soup with a spoon.
- Bake, cool, and freeze. Make the casserole on a lazy Sunday and double it, wrap it up, and stash one in the freezer. Then all you have to do is reheat and pretend you slaved over it on a busy weeknight.

Vicky Geiger says
I have been making this recipe for years after having it at a friend's house. One of the main problems is the length of time it is in the oven while cooking a turkey. Seeing your suggestion about slow cooker gave me an idea for this year. But I'm wondering if it comes out just as good as the oven..
