Ingredients for bean and cheese casserole

The perfect blend of creamy cheese and crispy tortilla magic for this vegetarian showstopper.

The cheddar and Monterey Jack combo is non-negotiable here—Kraft Natural or Sargento shredded cheeses melt beautifully without clumping. For the beans, La Favorita or Bush's refried beans have that perfect texture, but any high-quality canned variety works. The tortillas? Mission or Old El Paso corn tortillas are my go-to—they crisp up perfectly. Pro tip: look for tortillas labeled 'masa harina' for that authentic texture. The garlic and onion are the flavor base, so don't skip toasting them lightly in the butter before mixing with the cheese sauce.

No refried beans? Mash canned black beans or pinto beans with a little oil and salt for a similar texture. Cheese substitutes? Pepper jack or cotija add exciting variations. Running low on tortillas? Crushed tortilla chips work in a pinch (just add a splash of milk to bind them). The spices are crucial—the smoked chili powder gives that restaurant-quality depth. If you can't find it, regular chili powder with a pinch of liquid smoke works. For a dairy-free version, swap the heavy cream for full-fat coconut milk and use vegan cheese (though the texture will differ).

This casserole reheats like a dream—5 minutes at 350°F covered with foil brings back that crispy crust. Store leftovers for 4 days in the fridge, or freeze for 3 months (thaw overnight in the fridge). For meal prep, assemble everything except the tortilla topping, refrigerate, then bake with the topping fresh for maximum crispiness. The cheese sauce thickens as it cools, so if it seems too thick when mixing, add a splash of milk. And trust me, the extra 5 minutes toasting the tortillas in the oven is worth the crispy magic.

Step-by-step instructions for bean and cheese casserole

Here's how to create a perfectly layered casserole with a golden tortilla crust and gooey cheese center.

Heat the 1 tablespoon olive oil in a large skillet over medium heat. Add the ½ whole onion and 2 cloves garlic cloves, both diced, and cook for 5-6 minutes until the onion becomes translucent and the garlic releases its fragrant aroma. You'll know it's ready when the garlic just begins to turn golden—don't let it brown or it'll turn bitter.

While cooking, sprinkle in the 1 teaspoon cumin, 1 teaspoon chili powder, ½ teaspoon salt, and ¼ teaspoon black pepper. Stir these spices into the onions and garlic for 30 seconds to toast them slightly, which deepens their flavor. Remove from heat and let cool for 2 minutes before transferring to your mixing bowl.

In a large bowl, combine the 2 cups cheddar cheese and 1 cup Monterey Jack cheese with the sautéed onion and garlic mixture. Add the ½ cup heavy cream and ½ cup milk, then stir until the cheese melts completely and the mixture becomes smooth. If any cheese remains unmelted, place the bowl over a pot of simmering water for 1-2 minutes to gently melt it.

In a separate small bowl, melt the 2 tablespoons butter until fully liquid. Pour this melted butter into the cheese mixture and stir again. The sauce should be thick but pourable—if it's too thick, add 1 tablespoon milk at a time until it reaches the perfect consistency for layering. This sauce will form the creamy base of your casserole.

Preheat your oven to 375°F and grease a 9x9-inch baking dish with nonstick cooking spray. Spread half of the 2 cups refried beans evenly across the bottom of the dish, creating a thin, even layer. This bean layer will provide moisture and heartiness to your casserole.

Spread half of the cheese sauce mixture over the beans, using a spatula to create an even layer. Top with the remaining 1 cup refried beans, spreading them evenly. Finally, spread the remaining cheese sauce over the top. The layers should be about ½-inch thick each—this ensures even cooking and a perfect texture throughout.

Cut the 8 whole corn tortillas into ½-inch wide strips—this creates a lattice effect that allows the cheese to peek through while keeping the topping crispy. Brush each tortilla strip lightly with the remaining melted butter (if any remains) or with a bit of olive oil if needed. Arrange the tortilla strips in a crisscross pattern over the cheese layer, leaving small gaps for the cheese to bubble through during baking.

For extra crispiness, I like to spray the tortilla strips lightly with cooking spray before arranging them. This ensures they'll get golden brown and crispy rather than soggy. The tortilla lattice should cover the entire surface of the casserole, creating a beautiful pattern that will become perfectly crispy during baking.

Transfer the casserole to the preheated oven and bake for 25-30 minutes until the tortilla topping is deep golden brown and the cheese is fully melted and bubbly. The edges should be crispy, and you should see cheese bubbles forming through the tortilla lattice—this is your signal that it's ready.

For the final touch, broil the casserole for 2-3 minutes at the end to achieve an extra-crispy tortilla topping. Watch closely during broiling to prevent burning. Once done, remove from the oven and let it rest for 5 minutes before serving. This resting time allows the layers to set slightly, making it easier to cut clean slices.
