Ingredients for america's test kitchen black bean burger
Black beans, flaxseed, and panko create the perfect crispy-juicy burger base—no meat needed.
| Ingredient | Amount | Notes |
|---|---|---|
| Black Beans 🫘 | 1 ½ cups | Canned, drained and rinsed |
| Panko Breadcrumbs 🍞 | ¾ cup | For crispy texture |
| Ground Flaxseed 🌾 | 2 tbsp | Plus 6 tbsp water |
| Smoked Paprika 🌶️ | 1 tbsp | For smoky depth |
| Ground Cumin 🌿 | 1 tsp | Toasted for warmth |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Onion Powder 🧅 | 1 tsp | For savory base |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For frying |
| Vegan Mayonnaise 🥫 | 2 tbsp | For binding |
| Whole Wheat Flour 🌾 | 2 tbsp | For extra binding |
| Fresh Parsley 🌿 | 2 tbsp | Chopped, for garnish |
| Vegan Burger Buns 🍞 | 4 whole | Toasted for serving |
| Avocado 🥑 | 1 whole | Sliced, for topping |
The black beans are the heart of these burgers—low-sodium canned is best, but rinse them well to cut excess salt. Trader Joe's and Whole Foods carry great brands like Goya or Eden Organic. For the flaxseed, Bob's Red Milltoast regular breadcrumbs for 5 minutes in a dry pan to mimic it.
No smoked paprika? Substitute half the amount with regular paprika—it won't be as smoky, but still delicious. Running low on flaxseed? Chia seeds work too, but use the same ratio. The vegan mayo isn't just for flavor—it helps the patties hold together. Hellmann's Vegan or Just Mayo are my top picks, but any good-quality plant-based mayo will do. For extra crispiness, dip the patties in a little more panko before frying—double-dredge method for maximum crunch.
These burgers stay fresh for 3 days in the fridge, wrapped tightly in parchment. Freeze for up to 3 months by flattening them on a tray first, then transferring to a bag. Reheat in a skillet with a splash of water or in the oven at 350°F for 10 minutes. Pro tip: Toast your buns while reheating—it makes all the difference. Leftovers? Smash them into a veggie burger bowl for lunch the next day.
Why You'll Love This Recipe
- No-Fuss Assembly: I’ll be real—this burger comes together faster than a drive-thru order. Just mash the beans, mix in the panko and flaxseed, and shape them. No kneading, no waiting for dough to rise, just done.
- Smoky Depth Magic: That smoked paprika and cumin? Oh, it’s the secret weapon. The patties have this warm, earthy richness that makes them taste like a hug—crispy outside, tender inside, with a flavor that lingers (in a good way).
- Meal Prep MVP: Between us, this is my go-to for busy weeks. Make a batch, freeze half, and pull them out for tacos, sliders, or even a quick lunch. The flaxseed keeps them from drying out, so they reheat like a dream.

Step-by-step instructions for america's test kitchen black bean burgers
Here's how to make burgers that deliver on both the crispy crust and juicy center promises—every time.
Prepare the Flaxseed Egg and Mix Dry Ingredients
In a small bowl, combine the 2 tablespoons ground flaxseed with 6 tablespoons water and stir well. Let it sit for 5 minutes until it thickens into a gel-like consistency—this is your egg substitute. Meanwhile, in a separate bowl, whisk together the 0.75 cup panko breadcrumbs, 1 tablespoon smoked paprika, 1 teaspoon ground cumin, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1 teaspoon salt, and 0.5 teaspoon black pepper. I like to toast the cumin and paprika briefly in a dry pan first for deeper flavor, but it's not required.
This dry mix is the foundation of your burger's texture and flavor. The panko creates that perfect crispy crust, while the spices build layers of smoky, savory depth. Keep these ingredients separate until you're ready to combine them—this prevents the panko from absorbing too much moisture too early.
Combine Wet Ingredients and Form the Patties
In a large mixing bowl, mash the 1.5 cups drained and rinsed black beans with a fork until mostly smooth but still slightly textured—you want some chunkiness for better bite. Add the flaxseed egg, 2 tablespoons vegan mayonnaise, and 2 tablespoons whole wheat flour. Mix well until everything comes together into a thick, cohesive dough. The mixture should hold its shape when pressed between your fingers but still be pliable.
Here's where the magic happens: fold in the dry spice mixture, stirring gently until just combined. Don't overmix—just until the spices are evenly distributed. Divide the mixture into 4 equal portions (about 1/3 cup each) and gently shape them into 1-inch thick patties. I press down firmly to compact them, which helps create that perfect sear later. Let the patties rest for 10 minutes while you prepare your cooking surface.
Create the Crispy Crust and Cook to Perfection
Heat 1 tablespoon extra-virgin olive oil in a large skillet over medium heat until shimmering. Add the patties and cook undisturbed for 4-5 minutes per side, until they develop a deep golden-brown crust and internal temperature reaches 160°F when measured with an instant-read thermometer. The key here is patience—don't press down on the patties or they'll lose their shape and fail to develop that crispy exterior.
About 1 minute before they're done, add 2 tablespoons chopped fresh parsley to the pan. The parsley will sizzle briefly, releasing its fresh aroma and adding a bright finish to the burgers. Transfer the cooked patties to a paper towel-lined plate to drain any excess oil while you toast the buns.
Assemble the Burgers with Avocado Topping
Toast the 4 whole vegan burger buns in a dry skillet or toaster over medium heat for 1-2 minutes per side until golden brown and crisp. While they toast, slice the 1 whole avocado into 1/4-inch thick slices and arrange them on the bottom bun halves. Spread each avocado slice with a thin layer of the remaining vegan mayonnaise if you like extra creaminess.
Place a black bean patty on each avocado-topped bun bottom and top with the remaining bun halves. Press down gently to create a neat sandwich. Serve immediately while the patties are still warm and crispy—this is when they're at their absolute best. The contrast of the cool avocado, warm patty, and toasted bun makes every bite perfect.
Pro Tips For Making America'S Test Kitchen Black Bean Burger
- Drain and Rinse Beans: Don’t skip this—even canned beans. After draining, give them a quick cold-water rinse, then pat them thoroughly dry with a kitchen towel. The recipe counts on that texture, and damp beans mean a mushy, crumbly mess. (I learned this the hard way when my first batch fell apart.)
- Toast the Panko First: Spread the panko on a dry skillet over medium heat for 2–3 minutes until it’s golden and smells toasty. This adds a nutty depth and prevents it from absorbing all the moisture during mixing. (Yes, it’s an extra step, but your burgers will hold together better.)
- Mix Flaxseed with Water Early: Whisk the ground flaxseed with ¼ cup water before adding it to the wet ingredients. Let it sit for 5 minutes to form a gel—this mimics eggs and binds the patties far better than dry flax. (I used to just toss it in, and the burgers always crumbled.)
- Press Patties Firmly: Don’t be shy—pack the mixture into the patties with your hands until they’re about ¾-inch thick. The recipe’s structure relies on this, and skipping it leads to flat, sad burgers that won’t sear properly. (Think of it like making a meatloaf: pressure = stability.)
Perfect pairings for this america's test kitchen black bean burger
Crispy Bun Choices
For the perfect pairing, opt for toasted vegan burger buns—I love Dave's Killer Bread or Udi's for their sturdy structure. Toast them in a dry skillet over medium heat for 1-2 minutes per side until golden brown.
This step is non-negotiable—it prevents soggy buns and adds a satisfying crunch. 🍞
Looking for something lighter? Try lettuce wraps or portobello mushroom caps as a low-carb alternative. Just brush them lightly with olive oil and toast in the same skillet to mimic the texture of a traditional bun. The avocado topping will cling beautifully to the crispy edges.
Topping Combinations
Classic toppings like sliced avocado and pickles are a must, but don’t be afraid to get creative. Add caramelized onions for sweetness or spicy jalapeños for heat.
A drizzle of smoky chipotle mayo (mix Hellmann’s Vegan Mayo with 1 tsp chipotle powder) takes these burgers to the next level. 🥑
For a tangy kick, top with quick-pickled red onions (soak ½ cup sliced red onions in ¼ cup apple cider vinegar and 1 tsp sugar for 15 minutes). The acidity cuts through the richness of the patty, balancing every bite. Fresh cilantro or microgreens add a bright, herbaceous finish.
Side Dish Pairings
A crispy sweet potato wedge salad with avocado and lime complements the smoky flavors perfectly. Toss 2 cups cubed sweet potatoes with 1 tbsp olive oil, roast at 400°F for 25 minutes, then mix with diced avocado, lime juice, and salt.
The natural sweetness contrasts beautifully with the savory patty. 🥔
For a lighter option, serve with a cooling cucumber-dill yogurt sauce on the side. Mix ½ cup vegan yogurt with 1 tbsp chopped dill, 1 tsp lemon juice, and salt. Drizzle over a mixed greens salad with cherry tomatoes and shaved fennel for a refreshing balance.
Drink Pairings
A sparkling limeade made with sparkling water, fresh lime juice, and a touch of agave is my go-to drink. The effervescence cleanses the palate between bites, while the lime brightens the smoky flavors. For a boozy twist, add 1 oz gin or vodka per glass. 🍋
For beer lovers, a hoppy IPA like Sierra Nevada Pale Ale cuts through the richness of the burger. The bitterness from the hops balances the smoky, spiced notes of the patty.
If you prefer something lighter, a crisp lager like Corona or Heineken works beautifully with the avocado and tangy toppings.

Frequently asked questions
Why does the recipe use flaxseed instead of eggs?
The flaxseed mixture creates a perfect egg substitute that binds the patties without adding extra fat or cholesterol. When combined with water, it forms a gel-like consistency that mimics the binding properties of eggs while keeping the burgers moist and flavorful. Plus, it's a great plant-based option that works beautifully with black beans!
Can I make these burgers ahead of time?
Form the patties and refrigerate them on a tray for up to 24 hours before cooking. For longer storage, freeze them for 3 months. To reheat, cook in a skillet over medium heat for 3-4 minutes per side or bake at 375°F for 10 minutes. The texture holds up well, though they're best served fresh for maximum crispiness.
What if my patties fall apart when cooking?
Overmixing the ingredients is the most common cause. Handle the mixture gently when combining and shape the patties firmly but carefully. If they still crumble, try adding 1 extra tablespoon of flour or 1 more tablespoon of panko to the mix. Chilling the patties for 10 minutes before cooking also helps them hold together better.
Are these burgers gluten-free?
Not as written, but you can easily adapt them! Replace the panko with gluten-free breadcrumbs or crushed gluten-free cornflakes, and use a gluten-free flour blend instead of whole wheat flour. The flaxseed egg remains safe for gluten-free diets. Always check labels to ensure your other ingredients (like vegan mayo) are certified gluten-free.
How do I get extra crispy edges?
Use a mix of panko and regular breadcrumbs (50/50 ratio) for maximum crunch, and press the patties firmly when shaping. Cook in a hot skillet with medium heat until golden brown, then finish with 30 seconds per side on high heat for extra crispiness. A light spray of oil before cooking also helps create that perfect crust.
