How to Make Sweet Potato Burgers

These burgers rely on roasted sweet potato puree to bind the mixture while keeping each patty tender. The process is straightforward: roast the sweet potatoes until soft, mix the remaining ingredients, form patties and bake, then finish in a skillet for a crisp exterior.

Step 1: Make sweet potato puree

Roast whole sweet potatoes until tender, then scoop and mash the flesh into a smooth puree. Baking concentrates the flavor and dries the flesh slightly, which helps patties bind without becoming watery. For three to four medium sweet potatoes you should end up with about 2 cups of mashed sweet potato.

Step 2: Create patties

Combine mashed sweet potato with cooked quinoa, drained black beans, minced purple onion, finely diced jalapeño, sunflower seeds, oat flour, egg and seasonings. Mix thoroughly so the ingredients distribute evenly. Use a 1/2-cup scoop to portion the mixture, then wet your hands and shape into 1-inch-thick patties.

Step 3: Bake

Arrange the formed patties on a lightly greased baking sheet. Bake at 375°F (190°C) for about 30 minutes, flipping once halfway through so both sides set and lightly brown.

Step 4: Pan fry

For a crisp, golden exterior, finish the baked patties in a lightly oiled nonstick skillet over low–medium heat. Fry for 4–5 minutes per side until golden and slightly firm to the touch.

Topping Ideas

Customize these burgers with your favorite toppings. They pair nicely with creamy, tangy or crunchy elements. Suggestions:

• Thinly sliced purple onion
• Avocado or smashed guacamole
• Sprouts or baby greens
• Greek yogurt mixed with hot sauce
• Ketchup or a smoky tomato sauce
• Mustard or grainy Dijon

Freezer Instructions

These burgers freeze exceptionally well and keep you from wasting extras. The recipe yields about 12 patties, which makes batch cooking easy.

1. Allow cooked patties to cool completely on a wire rack.
2. Wrap each patty tightly in plastic wrap, pressing out excess air, then wrap in a layer of foil for added protection.
3. Place wrapped patties in a gallon-sized freezer bag or reusable freezer container and remove as much air as possible.
4. Freeze for up to 3 months.

To thaw: move frozen patties to the refrigerator overnight, or unwrap and defrost briefly in the microwave, then reheat in a skillet or oven until warmed through and crisped.

Recipe — Sweet Potato Black Bean Burgers

Full of texture and flavor, these Sweet Potato Black Bean Burgers make an excellent homemade veggie burger that’s both filling and freezer-friendly.

Ingredients (makes about 12 patties)

• 2 cups roasted sweet potato, mashed (about 3–4 medium sweet potatoes)
• 15 oz canned black beans, drained and rinsed
• 1/2 cup minced purple onion
• 2 cups cooked quinoa (about 1 cup uncooked)
• 2 tablespoons finely diced jalapeño (optional, for heat)
• 1/3 cup roasted, unsalted sunflower seeds
• 1/4 cup + 2 tablespoons oat flour
• 1 large egg
• 1 tablespoon ground cumin
• 2 teaspoons garlic powder
• 1/4 teaspoon sea salt
• 1 teaspoon olive oil (for cooking)

Instructions

1. Preheat the oven to 375°F (190°C). Line or lightly grease a baking sheet. Cut sweet potatoes in half, drizzle with a little olive oil, pierce with a fork and roast skin-side down for 50–60 minutes, until very tender.
2. While the sweet potatoes roast, combine black beans, cooked quinoa, minced onion, jalapeño, sunflower seeds, oat flour, egg and spices in a large mixing bowl. Mash the beans slightly so the mixture binds but still retains texture.
3. When sweet potatoes are cool enough to handle (about 10 minutes), scoop out the flesh and mash until smooth. Measure 2 cups of mashed sweet potato and mix thoroughly into the bowl with the other ingredients.
4. Preheat oven to 375°F if needed. Use a 1/2-cup scoop to portion the mixture and wet your hands to form 1-inch-thick patties. Place them on the prepared baking sheet.
5. Bake the patties for 15 minutes on one side, flip, then bake another 15 minutes (about 30 minutes total) until set and lightly browned.
6. Heat a teaspoon of olive oil in a nonstick skillet over low–medium heat. Pan-fry the baked patties for 4–5 minutes per side until golden and crisp on the outside.
7. Serve hot with your favorite toppings or store according to freezer instructions.

Tips & Notes

• Nutrition information below applies to the burger patty only, not a bun or toppings.
• If you prefer vegan patties, replace the egg with a flax egg (1 tbsp ground flax + 3 tbsp water) and add a little extra binding oat flour if needed.
• Adjust jalapeño and spices to taste. Toast the sunflower seeds lightly for extra flavor and crunch.
