Vegan Black Bean Burger

Last summer, I was grilling at a friend's place when their partner—who'd gone vegan a few months before—arrived hungry and a bit uncertain about what they could eat. I threw together these black bean patties on the spot, and watching their face light up when they bit into one with that smoky chipotle mayo was the moment I realized that satisfying doesn't require animal products, just intention and the right spices.

I've made these for weeknight dinners when I'm tired and want something quick that still feels special, and I've also brought them to potlucks where people genuinely fight over seconds. There's something about a burger that everyone—vegan or not—gathers around, and that's when you know you've made something right.

Ingredients

• Black beans: The foundation of texture and protein; draining and rinsing them prevents the patties from becoming mushy or too wet.
• Red onion and red bell pepper: These give you sweetness and bite in the same bite—don't skip mincing them small, or you'll get chunks instead of cohesion.
• Garlic: Two cloves minced fine; this is where umami lives in a vegan burger.
• Rolled oats and breadcrumbs: Your binding agents that keep everything holding hands instead of falling apart on the spatula.
• Ground flaxseed and water: This flax egg replaces traditional binders and adds a subtle nuttiness you won't expect.
• Smoked paprika, cumin, and chili powder: Layer these spices—don't just dump them in; they're what make someone say "what is this?" in the best way.
• Vegan mayo and chipotle peppers: The mayo keeps the mayo creamy while the chipotle brings heat and smoke that makes you lean back and breathe.

Instructions

Start with the flax egg:

Whisk ground flaxseed and water together and let it sit for 5 minutes—you'll watch it thicken into something that looks and feels almost like a real egg. This is the magic moment that holds everything together.

Mash those beans:

Don't pulverize them into a paste; you want texture, little bits you can see and feel. A fork or potato masher gives you control; a food processor makes them sad.

Bring it all together:

Toss the mashed beans with everything else in one big bowl and mix until it feels cohesive but not over-worked. Your hands work better than a spoon here if you're not worried about getting messy.

Shape and chill (optional but smart):

Divide into four equal portions and shape them into patties about 3/4 inch thick. If you have 15 minutes, pop them in the fridge—cold patties hold together better when they hit the heat.

Get the pan ready:

Heat olive oil in a nonstick skillet over medium heat until you can feel the warmth above it. The sizzle when you add the first patty should be satisfying, not aggressive.

Cook with patience:

Four to five minutes per side until they're golden and a little crispy on the edges. Don't poke them every 30 seconds; let them be.

Make the mayo while they cook:

Combine vegan mayo, minced chipotle peppers, adobo sauce, and lime juice in a small bowl. Taste it, then add more chipotle if you want to feel the heat, or more lime if you want brightness.

Toast the buns:

A toasted bun isn't essential, but it's the difference between eating a burger and enjoying one.

Assemble with intention:

Spread chipotle mayo on both buns, layer lettuce first (it keeps the bun from getting soggy), then tomato, onion, the warm patty, and avocado if you want richness. Top and serve while everything's still warm.

Pin It

I learned the hard way that these burgers are best served immediately, while the patties are still warm and the mayo is still cool. That contrast of temperatures is what makes every bite sing.

Flavor Variations That Work

A handful of fresh cilantro mixed into the patty base adds brightness and pairs beautifully with the chipotle. I've also added corn kernels for sweetness and texture, and once I threw in minced jalapeño for extra heat—all of these twists work because the black beans are a neutral canvas. If you want to go spicier with the mayo, add a second chipotle pepper or a splash of hot sauce, but go slow and taste as you go.

What to Serve Alongside

These burgers don't need much—a simple green salad with lime vinaigrette cuts through the richness of the mayo beautifully. Baked sweet potato fries are the classic move, but I've also served them with a cold coleslaw when it's hot outside and you want something fresh and crunchy alongside the warm burger.

Storage and Make-Ahead Magic

The patties will keep in the fridge for up to four days if you stack them between parchment paper, so you can make them Sunday and cook them throughout the week whenever hunger strikes. The chipotle mayo also keeps for about a week, which means you're always three minutes away from a satisfying lunch.

• Form patties the night before and refrigerate so they're extra sturdy when they hit the pan.
• Leftover mayo makes a genius spread for veggie sandwiches or a dip for roasted vegetables.
• Freeze cooked patties for up to two months—just reheat gently in a warm skillet with a little oil.

Pin It

These burgers sit at the intersection of satisfying and easy, which is where the best meals live. Make them once and they become the recipe you come back to.
