How to Make It
- Prep your skillet and buns. Place a large nonstick skillet over medium heat.Lightly toast the buns cut-side down until golden. Set aside.
- Mash the beans. Add rinsed black beans to a large bowl. Use a fork to mash about 2/3 of them, leaving some whole for texture.
- Build the mixture. Stir in onion, bell pepper, garlic, oats, flaxseed, tomato paste, smoked paprika, cumin, chili powder, salt, and pepper.Mix until it holds together. If it’s too wet, add 1–2 tablespoons more oats. If too dry, splash in 1 teaspoon water or a little olive oil.
- Form patties. Divide into 4 equal portions.With damp hands, shape into 3/4-inch thick patties, pressing edges to avoid cracks.
- Cook the burgers. Add 1 tablespoon olive oil to the hot skillet. Cook patties 3–4 minutes per side until browned with a slight crust. Don’t fuss with them too much—let them sear.
- Make the avocado slaw. In a medium bowl, mash avocado with lime juice, olive oil, syrup, salt, and pepper.Fold in cabbage and cilantro until coated. Taste and adjust seasoning.
- Assemble. Layer buns with lettuce, a hot burger patty, a generous scoop of avocado slaw, and any extras like tomato, onion, hot sauce, or vegan mayo.

Ingredients — Black Bean Patties
- 1 can (15 oz) black beans, drained, rinsed, and patted dry
- ½ small red onion, finely minced
- 1 small red bell pepper, finely diced
- 2 cloves garlic, minced
- ½ cup rolled or quick oats
- 2 tbsp ground flaxseed
- 1 tbsp tomato paste
- 1 tsp smoked paprika
- ½ tsp ground cumin
- ½ tsp chilli powder
- ½ tsp kosher salt, plus more to taste
- Black pepper to taste
- 1–2 tbsp olive oil for cooking
Ingredients — Avocado Slaw
- 1 ripe avocado
- 2 cups shredded cabbage (green, red, or a mix)
- 2 tbsp fresh lime juice
- 1 tbsp olive oil
- ½ tsp maple syrup or agave
- ¼ tsp salt
- ¼ cup fresh cilantro, chopped (optional)
- Black pepper to taste
For Serving
- 4 burger buns, toasted (use gluten-free if needed)
- Lettuce leaves or baby greens
- Sliced tomato and red onion (optional)
- Hot sauce or vegan mayo (optional)
Instructions
- Mash the Beans and Make the MixtureAdd the drained and patted-dry black beans to a large bowl. Mash about two-thirds with a fork, leaving some whole for texture. Stir in the onion, bell pepper, garlic, oats, flaxseed, tomato paste, smoked paprika, cumin, chilli powder, salt, and pepper. Mix until the mixture holds together — if too wet, add 1–2 tablespoons more oats; if too dry, add a teaspoon of water.Mash only two-thirds of the beans — a fully mashed mixture produces gummy, dense patties. Some whole beans give structure, texture, and better bite.
- Form and Cook the PattiesDivide the mixture into 4 equal portions. With damp hands, shape each into a ¾-inch thick patty, pressing the edges to smooth any cracks. Heat 1 tablespoon oil in a large nonstick skillet over medium heat. Cook patties for 3–4 minutes per side until browned with a slight crust. Don't move them — let them sear undisturbed.Cook on medium heat only — high heat burns the outside before the inside sets and the patty can fall apart when flipped. Flip once, after the crust has fully formed.
- Make the Avocado SlawIn a medium bowl, mash the avocado with lime juice, olive oil, maple syrup, salt, and pepper until smooth. Fold in the shredded cabbage and cilantro until evenly coated. Taste and adjust seasoning.Make the slaw just before serving — avocado browns quickly and the cabbage releases moisture over time. If making a short time ahead, press cling film directly onto the surface and refrigerate.
- Assemble and ServeToast the buns cut-side down in the skillet until golden. Layer each with lettuce, a hot patty, a generous scoop of avocado slaw, and any extras. Serve immediately.Serve immediately while the patties are hot and the slaw is cool — the temperature contrast is part of what makes this burger so satisfying.
Tips for the Best Results
- Pat beans dry before mashing — excess moisture is the main reason bean burger mixtures turn loose and patties fall apart.
- Mash only two-thirds of the beans — fully mashed beans produce a gummy, dense patty with no texture.
- Taste the mixture and season generously before cooking — beans need enough salt and spice to taste good on the bun.
- Cook on medium heat only and flip once — high heat burns the crust before the interior sets.
- Don't move the patties while they sear — undisturbed contact with the hot pan is what builds the crust that holds them together.
- Uncooked patties can be refrigerated for up to 24 hours or frozen for 2 months — cook from frozen over medium-low heat for 5–6 minutes per side.
- For gluten-free, use certified gluten-free oats and gluten-free buns or serve in lettuce wraps.

Common Mistakes to Avoid
- Over-mashing the beans: Leave some texture so the patties don’t turn gummy.
- Skipping the binder: Oats and flaxseed help the burgers hold together. Don’t omit both.
- Cooking on heat that’s too high: You’ll burn the outside before the inside sets. Medium heat is best.
- Forming patties too thick: Thick patties can split or stay soft in the middle.Aim for about 3/4 inch.
- Under-seasoning: Beans need salt and spices. Taste the mixture and adjust before cooking.
Recipe Variations
- Gluten-free: Use certified gluten-free oats and gluten-free buns or lettuce wraps.
- Spicy chipotle: Add 1 minced chipotle in adobo or 1/2 teaspoon chipotle powder to the mixture and a dash to the slaw.
- Herb-forward: Mix in chopped parsley or scallions and swap lime for lemon for a brighter profile.
- BBQ twist: Replace tomato paste with 1–2 tablespoons vegan BBQ sauce; top with pickles and red onion.
- Extra protein: Fold in 1/3 cup finely chopped walnuts or sunflower seeds for crunch and heft.
- Cheesy vibe (still vegan): Stir 1–2 tablespoons nutritional yeast into the burger mixture.
FAQ
How do I keep black bean burgers from falling apart?
Use solid binders like oats and ground flaxseed, mash only part of the beans, and form compact patties with smooth edges. Cook over medium heat and flip just once after a good sear forms.
Can I bake these instead of pan-searing?
Yes.
Bake at 400°F (205°C) on a parchment-lined sheet for 10–12 minutes, flipping halfway. Brush lightly with oil for a better crust.
What can I use instead of oats?
Use breadcrumbs (regular or gluten-free) or crushed cornflakes. Start with 1/2 cup and adjust until the mixture holds together.
Is the avocado slaw necessary?
Not required, but it adds creaminess and brightness without dairy.
If you skip it, add something tangy like pickles, a squeeze of lime, or a swipe of vegan mayo.
Can I use a food processor?
You can pulse the beans and oats a few times, but don’t puree. Over-processing leads to mushy patties. Hand-mixing gives better texture control.
How do I meal prep this recipe?
Form patties and refrigerate or freeze as directed.
Make the slaw right before serving. You can also pre-chop onion and pepper to save time.
What toppings go well with these burgers?
Try lettuce, tomato, red onion, pickled jalapeños, avocado slices, hot sauce, or vegan mayo. A squeeze of lime or a spoon of salsa is great too.
Do I need to dry the beans?
A quick pat dry with a paper towel helps.
Too much moisture makes the mixture loose. If it feels wet, add a tablespoon of oats at a time.
