Ingredients
- Ground beef or turkey: gives the dish rich flavor and a bit of texture use a lean option for less grease
- Diced onion: brings just enough sweetness and depth yellow or white onions both work well here
- Taco seasoning: is the secret for big flavor buy your favorite blend or use homemade if you like adjusting for spice
- Rotel tomatoes with green chilies: add a tangy kick and a little heat opt for mild or hot based on your preference
- Black beans: make the bake heartier and add fiber pick a can with no added salt if you want more control
- Frozen corn: adds pops of sweetness and color look for non GMO corn when possible
- Salsa: brings zest and moisture use a chunky or smooth salsa to your taste
- Shredded Mexican blend cheese: gives that gooey irresistible top buy cheese and shred it yourself for the best melt
- Crushed tortilla chips: create a crunchy layer that holds up under all the cheese use fresh chips so they stay crispy
- Optional toppings: such as sour cream avocado jalapenos green onions and cilantro finish the dish beautifully use whatever your family loves or what you have on hand
Step by Step Instructions
- Brown the Meat and Aromatics:
- In your large oven safe skillet cook the ground beef and diced onion over medium heat patiently until the beef is fully browned and the onions are tender and sweet If there is a lot of grease use a spoon to remove the extra fat
- Simmer with Seasonings:
- Sprinkle in the taco seasoning then pour in the Rotel black beans corn and salsa Stir very well and let this mixture heat and bubble together for about five minutes The flavors will blend and the vegetables will soften
- Add Cheese and Chips:
- Turn off the stove Stir in half of your shredded cheese The cheese will melt right in making the filling creamy Evenly scatter the crushed tortilla chips on top then sprinkle over the rest of the cheese
- Bake Until Bubbly:
- Slide the skillet into the preheated oven Bake for ten to twelve minutes until the cheese is fully melted and the edges start to bubble and turn slightly golden
- Rest and Top:
- Remove from the oven and let it sit for a few minutes so the cheese sets Top with your choice of sour cream avocado jalapenos green onions or cilantro Serve right from the skillet while hot

I am always amazed how the mix of crunchy chips and melty cheese gets everyone excited to dig in My own favorite way is with a big spoonful of cold sour cream and lots of fresh cilantro
