Ingredients for america's test kitchen black bean burger
Precision-measured ingredients transform black beans into burgers with umami depth and restaurant-quality texture.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Black Beans 🌱 | 1 ½ cups | Drained and rinsed thoroughly |
| Cremini Mushrooms 🍄 | ¾ cup | Finely chopped for texture |
| Walnuts 🥜 | ½ cup | Toasted and finely chopped |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For binding and richness |
| Liquid Smoke 🔥 | ½ tbsp | For authentic smoky depth |
| Nutritional Yeast 🧀 | ¼ cup | For cheesy umami flavor |
| Diamond Crystal Kosher Salt 🧂 | 1 tsp | For seasoning and binding |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground for heat |
| Garlic Powder 🧄 | 1 tsp | For aromatic depth |
| Onion Powder 🧅 | 1 tsp | For savory complexity |
| Smoked Paprika 🌶️ | 1 tsp | For smoky richness |
| Flaxseed Meal 🌾 | 2 tbsp | Mixed with water for binder |
| Water 💧 | ½ cup | For flax egg mixture |
| Whole Grain Breadcrumbs 🍞 | ½ cup | For structural integrity |
The walnuts and cremini mushrooms are critical for achieving that coveted meaty texture—toast the walnuts until fragrant to enhance their nuttiness. For mushrooms, finely chop them so they mimic ground meat without overpowering the flavor. Whole Foods or Trader Joe's carry high-quality cremini mushrooms year-round, while walnuts from Costco offer the best value. Diamond Crystal kosher salt is preferred here for its fine grain and clean flavor, though Morton works in a pinch. Nutritional yeast from Bob's Red Mill provides that essential umami punch without dairy—look for the fortified version for extra B vitamins.
No liquid smoke? A dash of smoked paprika plus a splash of soy sauce (ensure it's vegan) mimics the smoky depth. Substituting walnuts? Pecans or macadamias work, though texture will differ slightly. For mushrooms, shiitake or oyster mushrooms add depth but require more chopping. Flaxseed meal is non-negotiable for binding—it creates a gel-like consistency when mixed with water, mimicking egg's function. If you're short on time, pre-chopped mushrooms from the grocery store's salad bar section save effort, though fresh is always superior. The breadcrumbs should be whole grain for added fiber and texture—Pillsbury or Trader Joe's brands work well.
These patties hold together beautifully when shaped properly and refrigerated for up to 24 hours before cooking, making them ideal for meal prep. Store any leftovers in an airtight container for 4-5 days in the fridge or freeze for up to 3 months—they reheat just as well as they cook. For best results, portion the mixture into 4 equal patties using a kitchen scale for precision. The flax egg mixture should be prepared at least 10 minutes before mixing to allow the gel to form fully, ensuring optimal binding.

Step-by-step instructions for america's Test Kitchen black bean burgers
Here's the precise method for crafting burgers with robust texture and deep umami flavor.
Prepare the Flaxseed Egg and Toast the Walnuts
In a small bowl, whisk together the 2 tablespoons flaxseed meal and 0.5 cup water until fully combined. Let this mixture sit for 5 minutes while you work—this will create a gel-like binder that holds the patties together. Meanwhile, toast the 0.5 cup walnuts in a dry skillet over medium heat for 3-4 minutes until fragrant and lightly golden. Transfer to a cutting board and chop finely, reserving any released oil.
The flax egg is crucial for binding the moist ingredients without adding extra fat. Toasting the walnuts enhances their nutty depth and prevents them from becoming mushy during cooking. Chop them finely so they distribute evenly throughout the mixture and contribute to the patty's texture.
Cook the Mushrooms and Build the Base Mixture
Heat 1 tablespoon of the 0.25 cup extra-virgin olive oil in a nonstick skillet over medium-high heat. Add the 0.75 cup finely chopped cremini mushrooms and cook for 5-6 minutes until all moisture evaporates and they develop a golden brown color. Transfer to a food processor and pulse until finely minced.
In a large mixing bowl, combine the drained and rinsed 1.5 cups black beans, processed mushrooms, toasted walnuts, and remaining 0.15 cup extra-virgin olive oil. Add the 0.25 cup nutritional yeast, 1 teaspoon each of garlic powder, onion powder, and smoked paprika, 1 teaspoon diamond crystal kosher salt, and 0.5 teaspoon ground black pepper. Mix thoroughly with your hands or a sturdy spoon.
Incorporate the Binder and Liquid Smoke
Add the prepared flax egg mixture and 0.5 tablespoon liquid smoke to the bean mixture. Stir well to combine completely, then fold in the 0.5 cup whole grain breadcrumbs. The dough should be thick but workable—if it's too sticky, add 1 tablespoon more breadcrumbs. Cover the bowl and refrigerate for 30 minutes to allow the flavors to meld.
This chilling period is essential for developing flavor and improving texture. The liquid smoke adds that characteristic smoky depth without overpowering the natural umami from the beans and mushrooms. The breadcrumbs provide structure while absorbing any excess moisture, preventing a crumbly final product.
Shape and Chill the Patties
Divide the mixture into 4 equal portions (about 4 ounces each) and gently form into ¾-inch thick patties. Place them on a parchment-lined baking sheet and refrigerate for another 30 minutes. This second chilling ensures they hold their shape when cooking and prevents them from falling apart.
Handle the mixture gently when shaping to avoid compacting it too tightly. The patties should maintain their form but still feel soft to the touch. If any cracks appear during shaping, simply press them closed lightly—they'll hold together during cooking.
Cook to Perfect Doneness
Heat a nonstick skillet over medium heat until hot but not smoking. Add the patties and cook for 4-5 minutes per side, pressing down gently with a spatula during the first minute to ensure even contact. They're ready when the edges are golden brown and the internal temperature reaches 160°F.
For best results, avoid moving the patties excessively while cooking. The gentle pressing helps create a crisp exterior while maintaining juicy interiors. Serve immediately on toasted buns with your favorite toppings, or store in an airtight container for up to 3 days. The burgers will continue to develop flavor as they sit, making them even more delicious the next day.
Pro Tips For Making America'S Test Kitchen Black Bean Burger
- Cook Mushrooms Dry: Sauté the cremini mushrooms until they’re completely dry and golden—no wet spots. I learned this the hard way: any lingering moisture makes the patties soggy when you grill or pan-fry them later. Use a nonstick skillet and let them crisp for 8-10 minutes, stirring occasionally.
- Toast Walnuts Hard: Don’t just warm the walnuts—toast them until they’re deeply fragrant and slightly darker. I used to skip this, and the texture was always off. A dry skillet over medium heat for 5-6 minutes, shaking it often, makes all the difference in the crunch of the finished burger.
- Drain Beans Twice: Rinse the canned black beans first, then drain them in a fine-mesh strainer for a second time. The extra step removes excess starch, which keeps the patties from sticking together when you form them. Trust me, your burgers will hold their shape better.
- Chill the Mixture: Let the burger mixture sit in the fridge for at least 30 minutes before shaping. I was skeptical—why wait?—but it actually helps the flavors meld and makes the patties easier to handle without falling apart. Cold hands work better too.
Storing and reheating this america's test kitchen black bean burger
Refrigerator Storage
Store cooked black bean burgers in an airtight container with parchment paper between layers to prevent sticking. They’ll keep fresh in the fridge for 4-5 days, with flavors actually deepening over time.
I’ve found that letting them cool completely before storing preserves their texture better. Place the container on the middle shelf where temperatures stay most consistent. 💫
Freezer Prep
For long-term storage, freeze patties on a parchment-lined tray for 1 hour to prevent clumping, then transfer to a freezer bag with all air removed. They’ll maintain quality for up to 3 months.
Label with the date—these burgers reheat beautifully straight from frozen without losing their structure. I like using quart-sized freezer bags from Reynolds for easy stacking.
Reheating Methods
For stovetop reheating, warm patties in a nonstick skillet over medium-low heat for 3-4 minutes per side with a splash of water to prevent drying. Microwave reheating works too: cover with a damp paper towel and heat in 30-second intervals until reaching 160°F internally.
The gentle heat helps restore crispness while keeping the interior juicy. 🔥
Make-Ahead Tips
Shape patties and refrigerate them up to 24 hours ahead of cooking for better flavor development. For freezer prep, form patties before freezing—just thaw in the fridge overnight before cooking.
I’ve made a batch on Sunday and kept them ready for quick weeknight burgers. The key is maintaining that ¾-inch thickness during storage to ensure even reheating.
Reviving Texture
If patties seem dry after reheating, brush with 1 teaspoon olive oil and warm for 1-2 minutes in the skillet. The oil helps restore moisture without making them soggy.
For extra crispiness, press them gently with a spatula during the final 30 seconds of reheating. This works especially well for patties stored beyond 3 days.
Portion Control
When reheating, use a meat thermometer to check internal temperature—160°F is perfect for safety and texture. For microwave reheating, divide patties into single servings before microwaving to ensure even heating.
I’ve found that 2-minute intervals with stirring between each prevents overcooking. Always let them rest for 1 minute after reheating before serving. ✨

Frequently asked questions
Why do these black bean burgers need both mushrooms and walnuts?
The mushrooms add a meaty texture and umami depth when finely chopped, while the toasted walnuts provide structure and richness. Together, they create that satisfying bite that mimics ground meat without relying on processed binders. The walnuts also release oil during toasting, which helps bind everything together during mixing.
Can I make these burgers ahead of time?
Shape the patties and refrigerate them on a parchment-lined tray for up to 24 hours before cooking. For longer storage, freeze them raw for 3 months—just thaw overnight in the fridge. The chilling time actually improves flavor development and helps them hold together better when cooking.
What's the best way to prevent crumbling when cooking?
Handle the mixture gently when shaping and refrigerate the patties for 30 minutes before cooking. Press them lightly with a spatula during the first 1-2 minutes of cooking to help them set. Avoid overmixing the ingredients, which can create a dense, crumbly texture. The flax egg binder is key—let it sit for 5 minutes before using to maximize its effectiveness.
Are these burgers suitable for kids?
While these burgers are packed with flavor, they might be too savory for picky eaters due to the smoked paprika and liquid smoke. For a milder version, reduce the smoked paprika to ½ teaspoon and omit the liquid smoke entirely. The texture remains the same, but the flavor becomes more neutral. Always check for allergens like walnuts if serving to children with food sensitivities.
How can I make these burgers extra crispy?
For maximum crispiness, cook them in a dry, hot skillet over medium-high heat for 3-4 minutes per side. Press down gently with a spatula during the first minute to help them develop a golden crust. If using breadcrumbs, toast them lightly in the dry skillet before adding to the mixture. For oven-baked burgers, broil for 2-3 minutes at the end for extra crispiness.
