Everything you need for Mexican Cornbread Casserole is probably already hanging out in your pantry and fridge. Nothing fancy here-just bold, cheesy goodness waiting to be mixed, dumped, and baked into a glorious weeknight dinner.

• Jiffy corn muffin mix - The blue-box legend. Never lets you down, always shows up golden.

• Taco seasoning - The flavor shortcut we all rely on when we don't feel like measuring twelve different spices.
• Creamed corn - Corn, but make it extra creamy. The casserole glue you never knew you needed.
• Rotel tomatoes - A can of "notice me" with diced tomatoes and green chiles. Basically the Beyoncé of pantry staples.
• Chiles - Toss in a little heat or a lot, depending on whether you want dinner or a dare.
• Onions - Because every great casserole starts with making your kitchen smell like you know how to cook.
• Corn - Straight from the can (or frozen). Adds sweetness and those little golden pops of texture.

• Buttermilk - The tangy secret weapon that makes cornbread taste like it grew up in the South.

Ingredients

• ▢ 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

Storage:

Cover tightly or pop leftovers into an airtight container. They’ll keep for up to 3 days or freeze for 3 months.

Tips:

• 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.
