Base

  • Sweet potato (1 large, about 12–14 oz): Adds sweetness and helps bind the burger.
  • Shortcut: Use canned sweet potato puree (unsweetened) if you can find it.
  • Black beans, drained and rinsed (1 can, 15 oz): Adds protein and a hearty bite.
  • Swap: Pinto beans.

Flavor

  • Onion, finely chopped (1/3 cup): Adds savory depth.
  • Garlic, minced (2 cloves): Big flavor in a small amount.
  • Chili powder (1 tsp): Warm spice without being too hot.
  • Cumin (1/2 tsp): Gives that “burger” savory vibe.
  • Salt (3/4 tsp) + black pepper (1/2 tsp): Balances everything.

Binders

  • Eggs (1): Helps the burgers hold together.
  • Swap: Liquid egg substitute (1/4 cup).
  • Bread crumbs (1/2 cup): Soaks up moisture so the burger cooks up firm.

Mix, shape, and cook—easy veggie burgers that hold together
  • 1. Cook the sweet potato until very soft. Microwave 6–8 minutes (turning once), or bake at 425°F for 45–55 minutes. Scoop out and mash until smooth.
  • 2. Mash black beans in a bowl until mostly broken down but still a little chunky. Stir in onion, garlic, chili powder, cumin, salt, and pepper.
  • 3. Mix in mashed sweet potato, egg, and bread crumbs until the mixture holds together when pressed. If it feels too wet, add 1–2 tbsp more bread crumbs.
  • 4. Shape into 4–6 burgers and chill for 10 minutes if you have time. That little rest helps them firm up (and makes cooking easier).
  • 5. Cook in a lightly oiled skillet over medium heat for 4–5 minutes per side, until browned and hot through. If they brown too fast, lower the heat slightly.
  • 6. Assemble on buns with your favorite toppings and sauces.

Tips for Perfect Sweet Potato Black Bean Burger

  • Cook sweet potato until very soft: It blends smoother and binds better.
  • Keep some bean texture: A little chunkiness makes a better bite.
  • Chill before cooking: Even 10 minutes helps burgers hold shape.
  • Use medium heat: Too hot can brown the outside before the inside sets.
  • Flip gently: Use a thin spatula and let the first side brown well before turning.

Variations & Substitutions

  • Spicy version: Add diced jalapeño or hot sauce to the mix.
  • Smoky twist: Add 1/2 tsp smoked paprika.
  • Gluten-free: Use gluten-free bread crumbs and buns.
  • Extra savory: Add 2 tbsp grated Parmesan-style topping for richer flavor.
  • Leftover idea: Crumble cooked burgers into tacos or burrito bowls.

Make-Ahead & Freezing

Store cooked burgers in the fridge for up to 4 days. Reheat in a skillet over medium heat or in the oven at 375°F until hot.
To freeze, place uncooked shaped burgers on a parchment-lined tray, freeze until firm, then store in a freezer bag for up to 2 months. Cook from frozen on medium-low heat, a bit longer per side, until hot through.

Serving Suggestions & Pairings

  • Serve with baked fries, roasted veggies, or a crunchy slaw.
  • Pair with a simple green salad for a lighter weeknight dinner.
  • Add avocado, spicy mayo, or BBQ sauce for a fun flavor twist.
  • Great for meal prep lunches with extra toppings packed separately.
