Ingredient Spotlight

Panko breadcrumbs

Panko are Japanese-style breadcrumbs made from crustless white bread that’s processed into large, airy flakes; they crisp up much lighter and crunchier than regular breadcrumbs. They originate in Japan and are commonly used for frying and breading, producing a very light, crunchy coating. You can find panko in the Asian section or the breadcrumb aisle of most grocery stores, or at Asian markets. Good substitutes are regular dry breadcrumbs (for a denser crust), crushed saltine crackers or cornflakes, or homemade torn-bread crumbs toasted briefly to dry.

Ingredient Spotlight

Smoked paprika

Smoked paprika (Spanish pimentón) is a ground red pepper powder that’s been smoked over oak, giving it a distinctive smoky, slightly sweet flavor and deep red color; it’s a staple in Spanish cuisine. The aroma is smoky and earthy rather than fiery hot (there are sweet, hot, and bittersweet varieties). You’ll find it in the spice aisle or the international/Spanish foods section of supermarkets and at specialty spice shops. If you don’t have it, substitute regular sweet paprika plus a small pinch of cayenne or smoked salt, or use a little chipotle powder or a drop of liquid smoke to add smokiness.

Jake's note

"These burgers are great for backyard cookouts or weeknight dinners when you want something hearty but meat-free. The charred corn topping adds sweetness and crunch that makes the patties taste extra-special."

Grilled Lentil Burgers

Lentil burgers find their best expression on the grill: the direct heat gives the surface a smoky, caramelized crust while the interior stays toothsome thanks to slightly under-mashed green or brown lentils. This recipe leans into contrast — a rustic, slightly chunky patty bound with panko and egg and seasoned with smoked paprika and cumin, topped with bright, charred-sweet corn that cuts through the richness. The result delivers satisfying protein and texture that hold up on a bun without crumbling.

What makes this version work is attention to texture and timing: cook the lentils until just tender, pulse rather than puree, and chill the shaped patties so they firm up before hitting a hot grate. Grilling the corn alongside the burgers not only adds a sweet counterpoint but brings a hint of smoke that ties the whole sandwich together. It’s a recipe meant for backyard get-togethers and weeknight dinners alike—easy enough for a quick midweek meal, but with enough flavor and char to please meat-eaters and vegetarians at the same table.

Instructions

Cook the lentils

Rinse the lentils under cold water. Combine lentils and vegetable broth (or water) in a medium saucepan, bring to a boil, then reduce to a simmer and cook until just tender, about 18–22 minutes; do not overcook. Drain any excess liquid and let the lentils cool slightly so they’re easier to handle.

For this step

  • 1 cupDry green or brown lentils
  • 3 cupsLow-sodium vegetable broth or water
Cook the lentils

Make the burger mixture

Transfer warm lentils to a large bowl and mash with a fork or pulse a few times in a food processor until mostly broken down but still slightly chunky. Stir in the finely chopped red onion, minced garlic, panko, egg and the spice mix; season to taste and combine until the mixture holds together when pressed. Divide into four equal portions and shape into 3/4-inch-thick patties, then refrigerate 10–15 minutes to firm up.

For this step

  • 1 smallRed onion, finely chopped
  • 2 clovesGarlic, minced
  • 0.75 cupPanko breadcrumbs
  • 1 largeEgg (large)
  • 1 tbspSpice mix (smoked paprika, ground cumin, salt & black pepper), combined
Make the burger mixture

Prepare the grill

Heat a gas or charcoal grill to medium-high (about 400°F / 200°C). Brush the grates with olive oil to prevent sticking and lightly brush both sides of the patties with a little oil to help with browning. If you like, also brush the corn cobs with oil before placing them on the grill.

For this step

  • 2 tbspOlive oil (for brushing grill and patties)
Prepare the grill

Grill the corn and patties

Place the ears of corn on the grill: rotate occasionally until kernels are charred in spots, about 8–10 minutes; remove and let cool slightly. Grill the lentil patties over direct heat 4–5 minutes per side, or until nicely charred and firm to the touch. Use a spatula and avoid pressing the patties so they hold their juices and texture.

For this step

  • 2 earsFresh corn on the cob
Grill the corn and patties

Make the topping and assemble

Cut the charred kernels off the cobs and toss with a tablespoon of olive oil and a pinch of the spice mix (reserve extra for seasoning). Toast the buns briefly on the grill, then assemble each burger: place a lentil patty on the bun bottom, top with a generous spoonful of charred corn, and finish with the bun top. Serve immediately.

Tips from the kitchen

Don’t overcook lentils

Cook lentils until just tender so the mixture keeps some bite; soggy lentils turn gluey and make patties mushy.

Pulse, don’t puree

If using a food processor, pulse a few times — you want mostly broken-down lentils with some whole ones for texture, not a smooth paste.

Chill patties before grilling

A 10–15 minute chill firms the patties and reduces breakage on the grill; you can also shape and refrigerate up to an hour ahead.

Oil grates and patties

Brush the grill grates and both sides of the burgers with olive oil just before cooking to get a good sear and prevent sticking.

Flip gently once

Use a wide, thin spatula and flip only once to preserve the patty’s structure and capture the best crust without pressing out moisture.

Variations & substitutions

Vegan binder swap

Replace the egg with a flax or chia 'egg' (1 Tbsp ground flaxseed + 3 Tbsp water, rested 10 minutes) and add an extra 2–3 Tbsp panko or cooked quinoa to firm the mix.

Gluten-free option

Use gluten-free breadcrumbs or crushed gluten-free crackers in place of panko; you may need a tablespoon more binder to reach the right texture.

Spicy harissa twist

Stir 1–2 teaspoons harissa or a tablespoon of chopped roasted red pepper into the lentil mix and finish the corn with a squeeze of lime for a North African flare.

Cheesy interior

For a melty surprise, press a small cube of halloumi or pepper jack into the center of each patty before chilling, then grill as directed.

Storage & make-ahead

Store cooked lentil patties and charred corn separately in airtight containers in the refrigerator for up to 3–4 days. To freeze, flash-freeze shaped uncooked patties on a tray, then transfer to a labeled bag for up to 2–3 months; cook from frozen with a slightly longer grill time. Reheat refrigerated burgers on the grill or in a skillet over medium heat to restore the crust; avoid microwaving to prevent a soggy texture.

What to serve with it

Serve on toasted buns with simple additions like pickled red onions, sliced avocado, or a smear of lemony yogurt or smoky aioli to brighten the flavors. Pair with grilled sweet potato wedges, a crisp cabbage slaw, or a peppery arugula salad, and enjoy with a hoppy beer, a chilled rosé, or a citrusy mezcal cocktail to echo the char and corn.

Frequently asked questions

Can I use canned lentils instead of dry?

Yes — drain and rinse canned lentils thoroughly, then skip the cooking step and reduce the panko slightly because canned lentils hold more water; pulse fewer times to avoid a mushy texture.

How do I keep the patties from falling apart on the grill?

Make sure the mixture holds together when pressed before shaping, chill the patties to firm them up, oil the grates and patties, and flip only once with a wide spatula to minimize breakage.

Can I make the mixture ahead of time?

Yes — you can cook the lentils and mix the filling up to 24 hours ahead; shape the patties just before grilling or shape and keep them covered in the fridge for up to a day.

Are these burgers safe to eat without an internal temperature?

Because these contain egg, cook until the exterior is well-seared and the patty is firm and heated through; unlike meat, there isn’t a single target temperature for safety, but a thorough hot cook is recommended.

What’s the best way to reheat leftover burgers?

Reheat on a preheated grill or in a skillet over medium heat to crisp the exterior and warm the center; if frozen, thaw in the refrigerator overnight for best results before reheating.
