Ingredients Method

Ingredients

  

• 1 tablespoon olive oil
• 1 medium yellow onion, diced
• 3 cloves garlic, minced
• 1 1/2 pounds lean ground beef (90% lean or higher)
• 1 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper
• 2 teaspoons chili powder
• 1 teaspoon ground cumin
• 1/2 teaspoon smoked paprika
• 1 can (15 ounces) black beans, drained and rinsed
• 1 can (10 ounces) diced green chiles, mild or hot
• 2 cups red enchilada sauce (homemade or store-bought)
• 8–10 small corn tortillas (or 6 large flour tortillas, see Alternatives)
• 2 cups shredded Mexican blend cheese (or cheddar + Monterey Jack)
• 1/2 cup plain Greek yogurt or light sour cream (optional, for topping)
• 1/4 cup chopped fresh cilantro (optional)
• 1 medium avocado, diced (optional)
• Lime wedges, for serving (optional)

Method

 

1. Preheat the oven: Heat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
2. Sauté aromatics: Warm olive oil in a large skillet over medium heat. Add onion and cook 3–4 minutes until softened. Stir in garlic and cook 30 seconds until fragrant.
3. Brown the beef: Add ground beef, breaking it up with a spoon. Season with salt, pepper, chili powder, cumin, and smoked paprika. Cook 6–8 minutes until browned and no longer pink. Drain excess fat if needed.
4. Add beans and chiles: Stir in black beans and diced green chiles. Cook 1–2 minutes to warm through. Taste and adjust seasoning with a pinch more salt if needed.
5. Warm the sauce: In a small saucepan or microwave-safe bowl, gently warm the enchilada sauce. This helps it spread and soak into the layers evenly.
6. Prep tortillas: If using corn tortillas, stack and wrap them in a damp paper towel and microwave 20–30 seconds to soften. This prevents tearing during layering.
7. Layer the casserole: Spoon a thin layer of enchilada sauce into the baking dish. Add a single layer of tortillas (tear to fit as needed). Spread one-third of the beef mixture over the tortillas, drizzle with sauce, and sprinkle with one-third of the cheese. Repeat layers two more times, finishing with cheese on top.
8. Bake: Cover loosely with foil and bake 15 minutes. Remove foil and bake another 10–12 minutes, until cheese is melted and bubbling with lightly golden spots.
9. Rest and garnish: Let the casserole rest 8–10 minutes so it sets and slices cleanly. Top with dollops of Greek yogurt or sour cream, cilantro, and diced avocado if using. Serve with lime wedges.

Storage Instructions

• Refrigerator: Cool completely, then cover or portion into airtight containers. Store up to 4 days.
• Freezer: Wrap tightly in layers (plastic wrap, then foil) or use a freezer-safe container. Freeze up to 2 months.

  Thaw in the fridge overnight before reheating.

• Reheating: Oven at 325°F (165°C) for 15–20 minutes, or microwave individual pieces 1–2 minutes. Add a splash of water or extra sauce if it looks dry.

Benefits of This Recipe

• Protein-forward: Lean beef, beans, and cheese deliver a balanced, filling meal that supports muscle repair and steady energy.
• Balanced macros: Tortillas add satisfying carbs while the beef and beans bring fiber and protein. You can tweak fat and carb levels easily.
• Meal prep friendly: Makes multiple servings that store well, saving time on busy days.
• Accessible ingredients: Pantry staples and common grocery items keep cost and effort in check.

Common Mistakes to Avoid

• Using too much sauce in each layer: It can make the casserole soggy.

  Aim for a light, even coating between layers and a bit extra on top.

• Skipping the tortilla warm-up: Cold corn tortillas tear easily. Briefly heating them makes layering smoother.
• Under-seasoning the beef: The tortillas and beans are mild, so make sure the beef mixture tastes bold before layering.
• Overbaking: Too long in the oven dries out the layers. Bake just until the cheese bubbles and the center is hot.
• Slicing too soon: Resting time helps the layers set.

  Cut too early and it may fall apart.

Alternatives

• Protein swaps: Try ground turkey, chicken, or a plant-based crumble. Adjust seasoning and cook times as needed.
• Low-carb tweaks: Use low-carb tortillas or layer with thinly sliced zucchini or roasted bell peppers instead of tortillas.
• Sauce options: Use green enchilada sauce (salsa verde style) for a tangy twist, or blend red and green for a “Christmas” combo.
• Cheese choices: Swap in pepper Jack for more heat, or use reduced-fat cheese to lower calories while keeping protein high.
• Add veggies: Fold in sautéed bell peppers, corn, or spinach to boost fiber and color.
• Tortilla type: Corn brings classic flavor and holds up well; flour is softer and more neutral. Use what you prefer.

FAQ

Can I make this ahead of time?

Yes.

Assemble the casserole up to 24 hours in advance, cover tightly, and refrigerate. Add 5–10 extra minutes to the bake time if going straight from the fridge.

How spicy is this casserole?

It’s mildly spicy as written. For less heat, use mild chiles and a mild enchilada sauce.

For more heat, add a pinch of cayenne or use hot chiles and a spicier sauce.

What’s the best way to keep the layers from getting soggy?

Use a light hand with the sauce between layers and avoid watery add-ins. Warming the sauce and tortillas helps, and a short rest after baking lets everything set.

Can I use leftover cooked beef or shredded chicken?

Absolutely. Season it to taste with the listed spices, then combine with beans and chiles before layering.

This is a great way to repurpose leftovers.

Is there a gluten-free option?

Yes. Use certified gluten-free corn tortillas and a gluten-free enchilada sauce. Always check labels to be sure.

How can I increase the protein even more?

Use extra-lean beef, add an additional half can of black beans, and top with a bit more cheese.

A side of Greek yogurt also adds protein to each serving.

What sides go well with this?

Keep it simple with a crisp green salad, cilantro-lime rice, or roasted vegetables. Chips and salsa or guacamole are easy crowd-pleasers too.
