This burger mixes ground beef with mashed black beans, smoked paprika, and cumin to make a patty that’s juicier and more filling than a straight beef burger. The beans add bulk without watering things down, which makes this a smart pick when you’re feeding a group and want to stretch a pound of beef further. It comes together in about 35 minutes, and the chipotle mayo and avocado toppings do a lot of the flavor heavy lifting.
Smart swaps
- Smoked paprika: Regular paprika won’t cut it here — the smoked variety is doing real work. If you’re out, a small pinch of chipotle powder gets you close.
- Chipotle mayo: Mix a spoonful of adobo sauce from a can of chipotles into plain mayo. Canned chipotles are cheap and the rest of the can freezes well in a zip-lock bag.
- Black beans: Canned work perfectly. Drain and rinse them well, then pat dry with a paper towel — excess moisture is the enemy of a patty that holds together on the grill.
- Brioche or potato buns: Either works. If you’re cooking for a crowd, standard burger buns are cheaper and hold up just as well once toasted.
Before you start
The one thing that matters most here is how you mash the beans. You want them roughly mashed — about two-thirds broken down with some whole beans still visible. Fully pureed beans turn the patty dense and wet, and it won’t sear cleanly. Use a fork, not a food processor. The second thing worth knowing: chill your formed patties for at least 15 minutes before they hit the heat. This is especially important if you’re making a big batch. Cold patties hold their shape, cook more evenly, and are far less likely to fall apart when you flip them. If you’re prepping ahead for a cookout, you can form them hours in advance and keep them covered in the fridge on a parchment-lined sheet pan — stack them with parchment between each layer.
If something goes sideways
- Patties falling apart on the grill: The beans were probably too wet or the mix was overworked. Next time, dry the beans thoroughly and mix just until combined. For now, move the patties to a cast-iron skillet or flat griddle instead of open grates.
- Patties sticking to the grill: Don’t flip too early. Let them cook undisturbed until they release naturally — usually 3 to 4 minutes. Trying to force a flip is what causes tearing.
- Patties taste flat or bland: Black beans absorb seasoning, so this mix needs more salt than a plain beef patty. Season the outside of the formed patty with a pinch of salt right before cooking, not just in the mix.
- Center is still pink after the outside looks done: This is a beef-and-bean patty, so it’s thicker than a standard burger. Use an instant-read thermometer and pull it at 160°F (71°C). Don’t guess by color alone.
- Avocado browning before serving: Slice it right before the patties come off the heat. If you’re doing a big cookout spread, keep the avocado slices in a bowl with a squeeze of lime juice and cover with plastic wrap pressed directly against the surface.
Keeping and reheating
Cooked patties keep in the fridge for up to 3 days in an airtight container. To reheat, use a skillet over medium-low heat with a splash of water and a lid — about 3 to 4 minutes per side. This keeps them from drying out. Skip the microwave if you can; it turns the bean texture rubbery. For freezing, wrap uncooked formed patties individually in plastic wrap, then bag them. They’ll keep for up to 2 months. Thaw overnight in the fridge before cooking — don’t cook from frozen or the outside will scorch before the center hits 160°F.
Smoky Black Bean Hamburger
Ingredients
For the Burger Patties:
- 1 lb ground beef 80/20 lean-to-fat ratio for optimal juiciness
- 1 cup cooked black beans rinse and drain if canned
- ⅓ cup finely chopped red onion
- 2 cloves garlic minced
- 1 tsp ground cumin
- ½ tsp smoked paprika
- ½ tsp kosher salt
- ¼ tsp black pepper freshly ground
- 1 tbsp olive oil for skillet or grill
To Serve:
- 4 pieces burger buns preferably brioche or potato buns, toasted
- 4 servings toppings of choice lettuce, tomato, avocado, chipotle mayo, etc.
Instructions
- In a large mixing bowl, combine the ground beef and mashed black beans. The beans should be slightly chunky to maintain texture. Use your hands to mix until just combined—do not overwork the mixture.
- Add chopped red onion, garlic, cumin, smoked paprika, salt, and pepper to the bowl. Mix gently until the seasonings are evenly distributed.
- Divide the mixture into four equal portions and shape into patties about 1/2 inch thick. Press a slight indent in the center of each patty to prevent puffing during cooking.
- Heat olive oil in a cast iron skillet or grill pan over medium-high heat (around 375°F / 190°C). Once hot, add patties and cook for about 6–7 minutes per side, or until they develop a deep brown crust and reach your desired doneness.
- While the patties cook, toast the buns face-down in a dry pan or grill for about 1–2 minutes until golden and crisp at the edges.
- To assemble, spread chipotle mayo or desired sauce on the buns, layer with lettuce, tomato, avocado slices, and your black bean hamburger patty. Top with the other half of the bun.
Notes
- Want a Spicier Profile? Add 1 finely chopped chipotle pepper in adobo to the burger mix.
- For a vegetarian version, swap ground beef for mashed roasted sweet potatoes and a binder like breadcrumbs or crushed oats.
- To ensure a juicier patty, avoid pressing down on the burgers as they cook.

Your questions, answered
Can I make the patties ahead of time for a cookout?
Yes — this is one of the better burgers for prepping in advance. Form the patties, layer them on a parchment-lined sheet pan with parchment between each one, cover tightly, and refrigerate for up to 24 hours. Cold patties actually hold together better on the grill than freshly mixed ones.
How do I keep the patties from being too soft or mushy?
Skip the egg in the mix — it makes the patty mushy and the beans already provide enough binding. The bigger fix is drying your black beans thoroughly before mashing and not over-mashing them; you want texture, not paste.
Can I cook these on a gas grill instead of a skillet?
Yes, but use medium heat rather than high, and make sure your grates are clean and well-oiled. These patties are more delicate than an all-beef burger, so a screaming-hot grill increases the chance of sticking and tearing.
How do I know when the burger is fully cooked?
Use an instant-read thermometer and cook to 160°F (71°C) — this is a ground beef patty, so that’s the safe target regardless of color. The bean content can make the interior look done before it actually is, so don’t rely on visual cues alone.
