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.

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.
