Gather the ingredients for the corn and black bean Mexican casserole

You'll need a collection of fresh produce and some pantry staples for this Mexican-inspired casserole. Start with roma tomatoes, an onion, garlic cloves, and jalapeño for the roasted vegetable salsa. We used fresh corn on the cob for that sweet, charred flavor, but you can also use frozen corn if that's what you have. You'll also need cilantro, lime juice, ground cumin, and salt for seasoning. Supplement the corn with canned black beans, shredded Mexican-blend cheese, and corn tortillas. Optional garnishes include additional chopped tomato, cilantro, and sliced jalapeños.

Step 1: Preheat the oven

Preheat the oven to 400 F.

Step 2: Line baking sheets

Line two baking sheets with aluminum foil.

Step 3: Arrange the salsa ingredients on a baking sheet

Arrange the tomatoes, onion, garlic, and jalapeño on one baking sheet.

Step 2: Roast the salsa ingredients

Roast for 20–25 minutes, until charred. Let cool slightly.

Step 3: Arrange the corn on the other baking sheet

Meanwhile, toss the corn kernels with 1 tablespoon canola oil and spread them on the other baking sheet.

Step 4: Roast the corn

Roast for 10–15 minutes, stirring halfway, until lightly charred.

Step 5: Blend the salsa

Blend the roasted vegetables from the first sheet pan with the cilantro, lime juice, cumin, and salt.

Step 6: Mix the corn and beans

Mix the black beans with the roasted corn in a small bowl.

Step 7: Grease a baking dish

Grease a 9-inch baking dish.

Step 8: Arrange the casserole layers

Add 2 tortillas to the bottom of the pan, then layer on ½ cup of the black bean-corn mix, ⅓ cup of the salsa, and ⅓ cup cheese. Repeat the layers 2–3 times, until you run out of salsa and have used three-fourths of the corn mixture and cheese.

Step 9: Top with the remaining cheese and corn

Top with the remaining cheese and corn mix.

Step 9: Lower the oven temperature

Lower the oven temperature to 375 F.

Step 10: Bake the casserole

What other dishes can you serve with this vegetarian Mexican casserole?

We recommend pairing this corn and black bean casserole with a variety of Mexican starters and sides for a well-rounded meal. Traditional Mexican rice or green rice can help absorb the casserole's sauce and provide a neutral base. Grilled Mexican street corn will serve as a great appetizer alongside some fresh mango guacamole and chips.

If you're looking for protein, serve the dish with some carnitas, pork chili verde, and easy carne asada. Offer up a stack of warm tortillas on the side, allowing diners to create their own soft tacos using the proteins and the casserole as a filling. A variety of salsas, from mild pico de gallo to spicy salsa roja, and some sour cream will give you a whole taco bar spread.

To quench your thirst, serve this with spicy grapefruit mezcal margaritas. For dessert, channel your inner abuela and fry up a big stack of sopapilla

What other ingredients work well in a Mexican-inspired casserole?

There's no shortage of ways to take this Mexican-inspired casserole to another level, from crunchy toppings to more veggies and even meaty vegan crumbles hiding between the layers. Beyond black beans, try other types of beans, such as pinto, kidney, or refried beans, for added protein and variety. Adding other chiles, either mild poblano to chipotle or ancho peppers, will introduce more smokiness and heat to the salsa.

To amp up the veggie quota, incorporate diced sweet potatoes or butternut squash along with the corn. In summer, abundant zucchini, bell peppers, and spinach will help add even more colors and textures to the dish. For a meaty texture without meat, consider using crumbled tempeh or a plant-based ground meat alternative.

For a textural contrast, you can sprinkle crushed tortilla chips or Fritosd on top before baking. Finally, garnishes like pickled jalapeños or sliced radishes can add a zesty finishing touch to your Mexican-style casserole.
