Ingredients

Yield: 6 servings
  • 2 medium sweet potatoes, diced (about 3 cups)
  • 1 can (15 oz) black beans, drained and rinsed
  • 1 cup diced red bell pepper
  • 1/2 cup diced red onion
  • 2 cloves garlic, minced
  • 1 tsp ground cumin
  • 1 tsp smoked paprika
  • 1/2 tsp chili powder
  • 1 cup shredded cheddar cheese (or dairy-free alternative, optional)
  • 1/4 cup chopped fresh cilantro (optional)
  • 1 tbsp olive oil
  • 1/2 tsp salt
  • 1/4 tsp black pepper

Equipment

  • 9×13-inch baking dish
  • Mixing bowls
  • Chef’s knife
  • Cutting board
  • Measuring spoons

Instructions

1. Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish. For easier cleanup, line the dish with parchment paper. 2. In a large bowl, toss diced sweet potatoes with olive oil, cumin, smoked paprika, chili powder, salt, and pepper until evenly coated. Leave the skins on for extra fiber and nutrients. 3. Spread the seasoned sweet potatoes in the prepared baking dish. Roast for 20 minutes, stirring halfway through for even cooking. 4. Remove from oven and add black beans, red bell pepper, red onion, and garlic. Stir to combine. For extra flavor, sauté the onions and garlic first. 5. Sprinkle cheese evenly over the top (if using). Return to oven and bake for another 15-20 minutes, until sweet potatoes are tender and cheese is melted. Broil for 1-2 minutes at the end for a golden top. 6. Garnish with fresh cilantro before serving. Swap cilantro for parsley if preferred.

Tips for Better Results

  • Dice sweet potatoes uniformly for even cooking.
  • Spread the mixture in a single layer to achieve a crispier texture.
  • Double the batch and freeze half for easy future meals.

Variations

Spicy Version

Add 1 diced jalapeño or 1/2 tsp cayenne pepper for heat.

Vegan Option

Skip the cheese or use nutritional yeast for a dairy-free alternative.

Serving and Storage

Serve with a dollop of Greek yogurt or avocado slices for added creaminess. Store leftovers in an airtight container for up to 4 days. Reheat in the oven at 350°F for best texture.

Behind the recipes

Chef Liam Carter

I cook the way most people actually cook, after work, with what is already in the fridge, wanting something that feels like a reward rather than a compromise. Verdishia is where those recipes get written down: familiar comfort food, adjusted so it carries a little more protein and a few more vegetables, without losing the part that made you want it in the first place. No special equipment, no ingredient you will use once and forget. If a recipe cannot survive an ordinary Tuesday evening, it does not get published here.
