Ingredients
- 1 tablespoon olive oil
- 1 medium red onion, finely chopped
- 1 medium bell pepper, diced (any color)
- 1/2 lb sweet potatoes, peeled and cut into 1/2-inch pieces
- 4 garlic cloves, finely diced
- 1/2 jalapeño, finely diced
- 1 teaspoon smoked paprika
- 1 teaspoon ground cumin
- 1 teaspoon dried oregano
- 1/2 teaspoon salt
- 1/4 teaspoon ground black pepper
- 1 can (14 oz / 400 g) diced tomatoes
- 1 can (14 oz / 400 g) black beans, drained and rinsed
- 1 can (7 oz / 200 g) sweetcorn, drained and rinsed
- 1 1/2 cup low-fat cheddar cheese, grated
- Fresh cilantro, avocado, and scallions for garnish
Instructions
- Step 1: In a large ovenproof skillet, heat the olive oil over medium heat. Add the red onion and bell pepper, and sauté for a couple of minutes until the onion softens.
- Step 2: Stir in the sweet potato pieces. Cook for about 5 minutes, stirring occasionally, until they begin to soften.
- Step 3: Mix in the garlic and jalapeño, and cook for an additional minute until fragrant. Sprinkle in the smoked paprika, cumin, oregano, salt, and black pepper. Stir for about 30 seconds to let the spices bloom.
- Step 4: Preheat your oven to 375°F (190°C).
- Step 5: Pour in the diced tomatoes, then add the black beans and sweetcorn. Stir well to combine. Bring the mixture to a gentle simmer and cook for 10–15 minutes, stirring occasionally, until the sweet potatoes are tender. If the mixture appears too dry, add a splash of water.
- Step 6: Evenly distribute the grated cheddar cheese over the top of the mixture. Transfer the skillet to the preheated oven and bake for about 10 minutes, or until the cheese has melted and developed a light golden color.
- Step 7: Remove the casserole from the oven and let it rest for a couple of minutes. Sprinkle fresh cilantro, and add slices of avocado and chopped scallions just before serving.
Tips & Variations
- For a vegan version, substitute the cheddar cheese with a plant-based cheese alternative.
- Add a squeeze of lime juice before serving to brighten the flavors.
- If you like it spicier, increase the jalapeño amount or add a pinch of cayenne pepper.
- Serve with warm tortillas or a side of rice for a complete meal.
Storage
Store leftover casserole in an airtight container in the refrigerator for up to 3 days. To reheat, warm it gently in the oven or microwave until heated through. Adding a splash of water before reheating can help maintain moisture.

FAQs
Can I make this casserole ahead of time?
Yes, you can prepare the casserole up to the baking step, then cover and refrigerate it. Bake it when ready to serve, adding a few extra minutes if needed.
Can I use canned sweet potatoes instead of fresh?
Fresh sweet potatoes are best for texture and flavor. Canned sweet potatoes tend to be very soft and may result in a mushier casserole.
