Instructions
Step 1
Start by pulling out all your ingredients and getting them prepped — you'll want to dice your onions, mince that garlic, and have your taco seasoning ready to go. While you're prepping, crank your oven to 350°F and grab your 9x13 baking dish to lightly grease with cooking spray or a little butter. This gives the casserole a chance to warm up while you assemble everything, so you're not waiting around later. Your kitchen should smell amazing already, and that preheated oven is going to work its magic on that golden, bubbly crust we're all hoping for.
Step 2
Grab your favorite skillet and set it over medium heat—let it warm up for a minute or two until a drop of water sizzles and evaporates. While that heats, dice your onions and green peppers if you haven't already (about ½ inch pieces work great—they'll soften nicely and hold their shape). Toss the ground beef right into the center of the pan, letting it hit that hot surface with a satisfying sizzle. As it starts to brown, break it up with a wooden spoon and stir in your onions and peppers. You'll know it's ready when the beef is no longer pink and the veggies have softened and taken on a bit of color—about 5 to 7 minutes. Give it a taste and season with a pinch of salt and pepper if needed.
Step 3
Grab a few paper towels and gently dab the surface of your casserole — you're looking to lift excess grease without disturbing the layer beneath. Work in sections, pressing lightly so the towels absorb the oil but don't soak into your taco filling. The goal is to see the grease collect on the paper, leaving behind a cleaner, more balanced flavor in every bite.
Step 4
Grab your chili powder, cumin, paprika, dried oregano, salt, and pepper, and sprinkle them right over the sizzling meat mixture. Stir it all together so every bit of the meat gets a nice, even coating of that spice blend. Let it cook for just about a minute, stirring constantly, until the spices bloom and smell incredibly fragrant—you'll see the color deepen and know it's ready for the next step.
Step 5
Stir in the salsa and those black beans you drained earlier, scraping up any browned bits stuck to the pan. Let everything bubble gently for about 4 minutes, just until the mixture thickens slightly and the beans heat through. You'll know it's ready when the sauce clings to the back of a spoon and the edges start to look a little glossy.
Step 6
Start by grabbing your 9x13 inch baking dish and laying two flour tortillas flat on the bottom, overlapping them slightly so they cover the surface completely. Sprinkle about a third of your meat filling evenly over the tortillas, spreading it all the way to the edges with the back of a spoon. Top that with a generous third of your shredded cheese, making sure it's distributed evenly so every bite is melty and delicious. Now grab another two tortillas and layer them right on top of the cheese, followed by another third of the meat and cheese. Repeat this layering process one more time, ending with a final layer of tortillas and a generous sprinkle of cheese on top. Your casserole should look like a beautiful, cheesy mountain ready for the oven!
Step 7
**Step 7: Bake and Serve** Preheat your oven to 375°F (190°C). Pop that assembled casserole dish in the center of the oven and let it bake for about 20 minutes, until the cheese on top is fully melted, bubbly, and just starting to turn golden in spots. You’ll know it’s ready when you see the edges bubbling gently and the top looks deliciously melty. Carefully remove the dish from the oven (use oven mitts — that glass gets hot!) and let it rest for 5 minutes so it sets up a bit and is easier to slice. Garnish with your favorite taco toppings — maybe some fresh cilantro, a squeeze of lime, or a dollop of sour cream — and dig in while it’s warm.
Nutrition Information
My Tip
Before draining the cooked beef mixture, tilt the skillet slightly and spoon out as much grease as possible—those extra few teaspoons will keep your casserole from getting greasy and help the flavors stay balanced.
Leftovers
Store leftovers in a shallow airtight container to keep the layers intact and prevent sogginess. They’ll stay fresh in the fridge for up to 4 days—just peek at that bubbly top to know it’s ready to reheat.
Make It Your Own
For a lighter twist, swap the ground beef for seasoned ground turkey and use low-sodium chicken broth instead of water to keep the filling juicy. Top it with crushed baked tortilla chips instead of corn chips for a satisfying crunch without the extra grease.
