Step-by-Step Instructions
-
Step 1: Prepare Your Oven and Dish
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish. This will prevent the casserole from sticking and make cleanup easier later.
Small tip: Make sure your baking dish is oven-safe and has high enough sides to hold all the delicious layers.
-
Step 2: Brown the Ground Beef
Heat the olive oil in a large skillet over medium-high heat. Add the ground beef and cook, breaking it up with a spoon, until it’s fully browned. Drain off any excess grease from the skillet.
Small tip: Draining the grease is important for a less oily and healthier casserole.
-
Step 3: Build the Flavorful Filling
Add the chopped onion to the skillet with the browned beef. Cook for 3-5 minutes until the onion softens. Stir in the minced garlic and cook for another minute until fragrant.
Next, stir in the taco seasoning, diced tomatoes with green chilies (undrained), rinsed black beans, and drained corn. Bring the mixture to a simmer and cook for 5 minutes, allowing the flavors to meld together. Remove from heat.
-
Step 4: Prepare the Creamy Layer
In a medium bowl, whisk together the sour cream, milk, salt, and black pepper until smooth. This creamy mixture will add a wonderful richness to your casserole.
Small tip: For an extra tangy kick, you can add a squeeze of lime juice to the sour cream mixture.
-
Step 5: Assemble the Casserole
Spread about 1/2 cup of the meat mixture evenly on the bottom of your prepared baking dish. Arrange half of the flour tortillas over the meat layer, overlapping them slightly to cover the bottom. You may need to tear some tortillas to fit.
Spoon half of the remaining meat mixture over the tortillas. Drizzle half of the creamy sour cream mixture over the meat. Sprinkle with 1 cup of shredded cheese. Repeat these layers: remaining tortillas, remaining meat mixture, remaining creamy mixture, and finally, top with the remaining 1 cup of shredded cheese.
-
Step 6: Bake to Golden Perfection
Cover the baking dish loosely with aluminum foil. Bake for 20 minutes. Then, remove the foil and continue baking for another 15 minutes, or until the cheese is bubbly and lightly golden brown.
Small tip: If the cheese starts browning too quickly, you can loosely tent it with foil again.
-
Step 7: Rest, Garnish, and Serve
Once baked, remove the casserole from the oven and let it rest for 5-10 minutes before serving. This allows the layers to set and makes for easier slicing. Garnish with fresh cilantro and sliced green onions, if desired. Serve warm with extra sour cream or guacamole on the side.
Small tip: Resting is crucial! It helps the casserole hold its shape when you cut into it.
Tips & Variations
- Gluten-Free Option: Easily make this casserole gluten-free by swapping flour tortillas for corn tortillas. Ensure your taco seasoning is also gluten-free.
- Vegan or Vegetarian Option: Replace ground beef with a plant-based crumble or cooked lentils. Use vegetable broth instead of any beef broth. For the creamy layer, use dairy-free sour cream and milk, and choose a vegan shredded cheese blend.
- Boost the Veggies or Protein: Feel free to add diced bell peppers, zucchini, or mushrooms to the meat mixture while it’s cooking. For extra protein, shredded cooked chicken or turkey can be used in place of ground beef.
- Make it Spicy: For those who love a kick, add a diced jalapeño or serrano pepper to the onion and garlic. A pinch of cayenne pepper or a dash of your favorite hot sauce in the meat mixture will also do the trick!
- Make Ahead Tip: Assemble the entire casserole a day in advance, cover it tightly, and refrigerate. When ready to bake, add an extra 10-15 minutes to the covered baking time since it will be chilled.

Health Benefits
This Million Dollar Tex Mex Casserole isn’t just delicious; it also packs some great nutritional benefits!
The ground beef provides a significant source of high-quality protein, which is essential for muscle repair and growth. It also delivers iron, vital for healthy red blood cells, and B vitamins like B12, important for energy and nerve function.
Black beans are a powerhouse of nutrition. They are rich in dietary fiber, which aids digestion and can help regulate blood sugar levels. They also offer plant-based protein, folate, and magnesium, contributing to heart health and overall well-being.
Corn adds a touch of natural sweetness and more fiber to the dish. It’s also a source of antioxidants, like lutein and zeaxanthin, which are beneficial for eye health. The tomatoes with green chilies contribute Vitamin C for immune support and lycopene, a powerful antioxidant.
Even humble ingredients like onions and garlic play a role! They are known for their anti-inflammatory properties and contain various beneficial compounds and antioxidants that support a healthy immune system.

Storage Tips: Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days.
