How to Make Sweet Potato Black Bean Burgers

This burger is straightforward but benefits from a little time and care. Here’s how to achieve the ultimate plant-based patty:

1. Roast the Sweet Potatoes

  • Preheat oven to 400°F (204°C).
  • Halve sweet potatoes lengthwise and lightly brush or spray with olive oil.
  • Place cut side down on a baking sheet lined with parchment paper.
  • Roast for 30–35 minutes until tender all the way through.
  • Cool slightly, then scoop out flesh and mash with a fork or potato masher.

2. Prepare Other Key Ingredients

  • While potatoes roast, cook brown rice or quinoa as directed (if not already prepared).
  • Finely dice green onions; pulse walnuts or pecans in a food processor until a coarse meal forms.
  • Drain and rinse black beans thoroughly. Pat dry with a clean towel to remove excess moisture.

3. Combine the Burger Base

  • In a large mixing bowl, add mashed sweet potato, cooled rice/quinoa, black beans, green onion, nut meal, cumin, smoked paprika, salt, pepper, chipotle powder (if using), and brown sugar (if using).
  • Mix well to fully combine, ideally with clean hands for even texture.
  • Gently mash some black beans as you mix for binding, leaving a few whole for texture.

4. Shape and Bake the Patties

  • Preheat oven to 375°F (190°C). Lightly grease a baking sheet or line with parchment paper.
  • Scoop 1/3-1/2 cup portions of the mixture and form into burger patties, about 1/2-inch thick.
  • Place formed patties on the baking sheet and lightly brush the tops with a bit of olive oil.
  • Bake for 20 minutes, then gently flip and bake another 15–20 minutes. Patties should be golden brown and feel firm at the edges.
  • For crispier burgers, pan-fry in a little oil after baking for 2–3 min per side.

Success Tips & Substitutions

  • Don’t Over-Mash: Keep a bit of texture in the black beans and nuts for bite.
  • Rice Options: Brown rice gives hearty structure, while quinoa offers a lighter feel. For extra nutrition, try black rice or buckwheat (as some recipe reviewers have enjoyed).
  • Nut-Free Version: Use almond meal, oat flour, or seed meal if nut allergies are an issue.
  • Flavor Boosts: Up the smokiness with extra smoked paprika or chipotle powder.
  • Batch Cooking: Form raw or baked patties and freeze between parchment layers up to 1–2 months.

Serving Suggestions

  • Classic: Stuff burgers into toasted buns with sliced avocado, crispy lettuce, red onion, and tangy BBQ sauce.
  • Salad Bowl: Serve a burger atop a bed of greens with shredded carrots, radish, sprouts, and a citrusy tahini dressing.
  • Protein Plate: Pair alongside roasted veggies and quinoa or millet for a balanced, bun-free meal.
  • Brunch Style: Top with sautéed mushrooms and a dollop of vegan sour cream.

Storage & Make-Ahead

  • Fridge: Keep cooked burger patties in an airtight container for up to 3–4 days.
  • Freeze: Lay cooled patties between parchment in a freezer-safe bag for up to 2 months. Thaw overnight in the fridge, then reheat on the stove or in the oven.
  • Reheating: Warm baked burgers in a skillet over medium heat or in a 350°F oven until hot and crisp on the edges.

Frequently Asked Questions (FAQs)

Q: Can I make these burgers gluten-free?

A: Yes—use cooked brown rice, quinoa, millet, or buckwheat, which are all gluten-free, and serve on certified gluten-free buns or lettuce wraps.

Q: How do I keep the patties from falling apart?

A: Make sure black beans are very well drained, and mash the mixture enough to bind without making it soupy. Baking dries the mixture and helps firm the patties.

Q: Can I freeze the burger mixture or cooked burgers?

A: Absolutely. Shape the burgers and freeze raw or cooked, layering with parchment paper to prevent sticking.

Q: What nuts or seeds can I substitute for walnuts/pecans?

A: Use almond meal for a mild flavor, or sunflower/pumpkin seeds for a nut-free, crunchy texture.

Q: Are the burgers spicy?

A: The base burger has a mild smoky warmth. Add more chipotle powder or hot sauce in the mix if you prefer extra heat.
