Ingredients

Vegetables

• 4 medium sweet potatoes (about 2 pounds), peeled and cut into 1-inch cubes
• 1 red bell pepper, diced
• 1 small red onion, diced
• 2 cloves garlic, minced

Beans and Corn

• 1 can (15 ounces) black beans, rinsed and drained
• 1 cup corn kernels (fresh, frozen, or canned)

Dairy

• 2 cups shredded cheese, such as cheddar

Garnish

• 1/4 cup fresh cilantro, chopped (optional)

Pantry

• 1 tablespoon olive oil
• 1 lime, juiced
• 1 teaspoon ground cumin
• 1 teaspoon paprika
• 1/2 teaspoon chili powder
• Salt, to taste
• Black pepper, to taste
• 1 cup vegetable broth

Instructions

Preheat and prepare

Set your oven temperature to 375°F (190°C) and allow it to fully preheat while you prepare the ingredients.

Cook the sweet potatoes

Place the sweet potato cubes in a large pot and cover with cold water. Bring to a boil over high heat, then reduce to medium and cook for 10 minutes or until fork-tender. Drain completely and set aside to cool slightly.

Sauté the vegetables

Heat olive oil in a large skillet over medium heat. Add the diced onion and bell pepper, cooking for about 5 minutes until they become tender and fragrant. Stir in the minced garlic and cook for an additional minute, being careful not to let it burn.

Combine the filling

In a large mixing bowl, combine the cooked sweet potatoes, black beans, corn, sautéed vegetables, cumin, paprika, chili powder, lime juice, salt, and black pepper. Mix thoroughly to ensure the seasonings are evenly distributed throughout.

Layer the casserole

Lightly grease a 9×13-inch baking dish with cooking spray or butter. Spread half of the sweet potato and black bean mixture evenly across the bottom of the dish. Sprinkle half of the shredded cheese over this layer. Add the remaining sweet potato mixture in an even layer, then top with the rest of the shredded cheese.

Add moisture and bake

Pour 1 cup of vegetable broth evenly around the edges of the casserole to keep everything moist during baking. Cover the baking dish tightly with aluminum foil and place in the center of the preheated oven. Bake for 30 minutes.

Finish uncovered

Remove the foil and continue baking uncovered for an additional 15 minutes, allowing the cheese to melt completely and develop a golden, slightly crispy top.

Rest and serve

Let the casserole cool for 5-10 minutes before serving. This allows the layers to set and makes serving easier. Garnish with chopped fresh cilantro if desired and serve warm.

Pro Tips

• Use freshly shredded cheese rather than pre-shredded for better melting and creamier texture.
• Don’t overcook the sweet potatoes during boiling—they’ll continue cooking in the oven.
• Adjust the chili powder to your heat preference; add a pinch of cayenne for extra kick.
• Let the casserole rest after baking so the layers hold together when serving.
• For extra depth, add a teaspoon of smoked paprika or a dash of hot sauce to the mixture.
• If the top browns too quickly, tent loosely with foil during the final baking stage.

Ingredient Substitutions

• Sweet potatoes: Replace with butternut squash or regular potatoes for a different flavor profile.
• Black beans: Use pinto beans, kidney beans, or chickpeas instead.
• Cheddar cheese: Try Monterey Jack, pepper jack, or a Mexican cheese blend.
• Corn: Fresh roasted corn adds wonderful sweetness; canned works perfectly in a pinch.
• Bell pepper: Use poblano peppers for a mild smoky flavor or jalapeños for heat.
• Vegetable broth: Chicken broth works if not keeping the dish vegetarian.

Serving Suggestions

This casserole is satisfying on its own, but these accompaniments take the meal to the next level:

• A dollop of sour cream or Greek yogurt on top
• Fresh avocado slices or guacamole
• A crisp green salad with lime vinaigrette
• Warm flour or corn tortillas on the side
• Tortilla chips and salsa for added crunch
• Pickled jalapeños or hot sauce for heat lovers

Storage & Reheating

This casserole stores beautifully and tastes even better the next day as the flavors meld.

Refrigerator: Store covered in the baking dish or transfer to an airtight container for up to 4 days.

Reheating: Warm individual portions in the microwave for 2-3 minutes, or reheat the entire casserole covered with foil at 350°F for 20-25 minutes.

Freezing: Cool completely, wrap tightly in plastic wrap and aluminum foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

Make-ahead: Assemble the entire casserole up to 24 hours in advance, cover, and refrigerate. Add 10 extra minutes to the covered baking time if starting from cold.

Frequently Asked Questions

Q: Can I make this vegan?
Yes—simply omit the cheese or use a plant-based cheese alternative. The casserole will still be delicious and flavorful.

Q: Can I add meat to this recipe?
Absolutely. Cooked ground beef, turkey, or shredded chicken can be mixed into the layers for added protein.

Q: What if I don’t have vegetable broth?
You can use water in a pinch, though broth adds more flavor. Alternatively, dissolve a vegetable bouillon cube in hot water.

Q: How do I prevent the casserole from being too dry?
Make sure to add the full cup of broth and don’t skip covering with foil during the first baking stage. This traps moisture and keeps everything tender.

Q: Can I use canned sweet potatoes?
Fresh sweet potatoes are recommended for best texture and flavor, but drained canned sweet potatoes can work in a time crunch.
