intro

Juicy, grilled plant-based burger with melty cheese and classic toppings, matching traditional beef burger savoriness for every guest at summer cookouts.

Ingredients

Impossible ground plant-based meat 454g (1 standard package)
Sharp cheddar cheese slices 112g (4 slices, 28g each)
Brioche hamburger buns 240g (4 split buns)
Canola oil 30ml (2 tablespoons)
Kosher salt 5g (1 teaspoon)
Freshly ground black pepper 2g (1/2 teaspoon)
Green leaf lettuce 40g (4 large leaves)
Beefsteak tomato 80g (4 1/4-inch thick slices)
Red onion 30g (4 thin 1/8-inch slices)
Dill pickle slices 28g (8 slices)
Mayonnaise 60g (4 tablespoons)

Steps

1

Form burger patties

Divide the 454g of cold Impossible ground meat into 4 equal 113g portions. Gently shape each into 4-inch wide, 1/2-inch thick patties, making a 1/4-inch shallow dimple in the center of each to prevent bulging while grilling. Season both sides of each patty evenly with 5g kosher salt and 2g black pepper, then set on a plate for 5 minutes at room temperature while the grill preheats.

step1:Form burger patties
2

Preheat outdoor grill

Preheat a gas or charcoal grill to medium-high heat (200°C / 400°F), roughly 10 minutes for gas or 20 minutes for charcoal; form patties during this preheat window to save time. Once hot, scrub grill grates clean with a wire brush, then use long tongs to wipe grates with a paper towel coated in 30ml canola oil to prevent sticking. Close the lid and let grates heat for an additional 2 minutes.

step2:Preheat outdoor grill
3

Sear the patties

Place the 4 seasoned patties dimple-side down directly on the hot oiled grates, leaving 1 inch of space between each patty for even air flow. Close the grill lid and cook for 3 minutes without moving or flipping the patties, until the bottom side develops deep, dark brown grill marks and a slightly crispy crust. Do not press down on the patties while cooking, as this will squeeze out flavorful moisture.

Step 3
step3:Sear the patties
4

Add cheese and finish

Use a thin, flexible metal spatula to flip each patty, then immediately place one 28g slice of sharp cheddar on top of each seared patty. Close the grill lid and cook for an additional 2 to 3 minutes, until patties reach an internal temperature of 71°C (160°F) for ideal doneness and the cheese is fully melted and bubbling slightly around patty edges. Transfer cooked patties to a clean plate and let rest for 2 minutes.

step4:Add cheese and finish
5

Toast the brioche buns

Place the split cut sides of the 4 brioche buns face-down on the cooler outer edge of the grill grates, away from direct high heat. Toast for 45 seconds to 1 minute, until the cut surface is light golden brown and slightly crisp, watching closely to avoid burning. Remove toasted buns from the grill and arrange on a serving platter for assembly.

step5:Toast the brioche buns
6

Assemble finished burgers

Spread 15g (1 tablespoon) of mayonnaise evenly across the cut sides of each toasted bottom and top bun. Layer each bottom bun with one lettuce leaf, one tomato slice, one red onion slice, two pickle slices, one rested cheesy patty, then cap with the top bun. Press down gently to secure layers, and serve immediately while hot.

Tips

1.Keep Impossible meat cold until forming patties; warm plant-based fat is sticky and can lead to overworked, tough patties that fall apart on the grill.
2.Avoid pressing down on patties while grilling, as this squeezes out the juicy, beef-like plant oils that give Impossible burgers their signature moist, meaty texture.
3.Oil your grill grates well before cooking, as plant-based patties can stick more easily to hot metal than traditional beef patties if grates are unoiled.

Impossible Burger:Frequently Asked Questions

1.Do I need to thaw Impossible ground meat before forming and grilling patties?
You can grill frozen Impossible patties in a pinch, but fridge-thawing it for 24 hours first makes forming even, consistent patties far easier. Thawed meat cooks more evenly too, so you won’t end up with charred outsides and underdone centers, no fancy quick-thaw hacks required.
2.Why do my grilled Impossible burgers always puff up into a round dome shape?
That puffing happens as the plant-based proteins bind and tighten when exposed to high heat. Fix it by pressing a shallow 1-inch dimple right in the center of each raw patty after forming. Never press down on the patty while it grills, as that squeezes out all the juicy, savory moisture you want.
3.How much kosher salt should I add to Impossible meat before grilling?
Use 1 teaspoon of kosher salt per pound of Impossible ground meat, mixed in very gently right before you form patties. Don’t salt it hours ahead of time, as that can draw out moisture and make the final patty tough, just like it would with traditional ground beef.
4.Can I prep the Impossible patties the night before a summer cookout?
Absolutely! Form your lightly salted patties, stack them between small squares of parchment paper, seal them in an airtight container, and store them in the fridge for up to 24 hours before grilling. Don’t leave them sitting out at room temp for more than 20 minutes before cooking to avoid food safety risks.
5.What grill temperature works best for juicy, non-burnt Impossible burgers?
Aim for a medium-high grill temp, around 400–450°F, and give your grates a light coat of canola oil right before adding patties to prevent sticking. This temp creates a nice, savory sear on the outside without burning the patty before the center cooks through to that perfect juicy bite.
6.How long do I grill Impossible burger patties to keep them juicy?
Grill 3–4 minutes per side for a juicy, medium-well finish that matches the texture of a classic beef burger. Resist the urge to squish the patties with your spatula while they cook—that presses out all the flavorful, juicy plant-based fat that makes the burger taste rich and satisfying.
7.When should I add sharp cheddar slices to get perfectly melted cheese?
Add your sharp cheddar slices to the top of each patty during the last 60–90 seconds of grilling. Close the grill lid for that window to trap heat, so the cheese melts into a smooth, gooey layer that sticks to the patty instead of sliding off when you build your burger.
8.Should I oil the grill grates or the patties themselves to prevent sticking?
I recommend oiling preheated grates lightly with canola oil (held on a folded paper towel with long-handled tongs) right before adding patties. Oiling the patties themselves can cause excess flare-ups as oil drips off, leading to uneven charring and burnt spots that ruin that balanced, savory flavor.
9.How do I keep brioche hamburger buns from getting soggy?
Toast your brioche buns cut-side down on the cooler edge of the grill for 30–45 seconds right before building your burgers. The light, toasty crust creates a barrier that keeps juicy patty drippings and wet condiments from soaking into the soft bun and turning it mushy mid-meal.
10.Why do my Impossible burgers stick to the grill even when I oil the grates?
Sticking almost always happens if you try to flip the patties too early. Let the first side cook for a full 3 minutes undisturbed—this lets the seared crust form fully, so the patty releases easily from the grates when you’re ready to flip, no scraping or torn patties required.
11.Can I cook these Impossible burgers on a charcoal grill instead of gas?
Definitely! Charcoal grills work beautifully for that classic smoky cookout flavor. Just wait until the coals are covered in light gray ash before adding patties, so you get consistent medium-high heat without harsh, acrid smoke from unburnt charcoal that can make patties taste bitter.
12.How thick should I form my Impossible patties for grilling?
Form patties to about ½-inch thick, and make them slightly wider than your brioche buns, since they’ll shrink a tiny bit as they cook. Don’t overwork the meat when forming—squeeze it just enough to hold together, as overmixing leads to dense, tough patties instead of tender, juicy bites.
13.Are these grilled Impossible burgers safe for guests with beef allergies?
Yes! Impossible ground plant-based meat contains no beef or animal products, so it’s a great pick for vegan, vegetarian, and beef-allergic guests. Just use separate grilling tools and a clean grill section to avoid cross-contamination from any beef burgers you make for other guests.
14.Do I need extra seasonings besides kosher salt for the patties?
You don’t have to! Impossible meat is already formulated to match the savoriness of ground beef, so a light sprinkle of kosher salt is all you need to amp up that flavor. If you want extra depth, add a pinch of black pepper or garlic powder, but skip heavy spice mixes that overpower that classic burger taste.
15.How should I store leftover grilled Impossible burgers?
Let leftover cooked patties cool completely, then store them in an airtight container in the fridge for up to 3 days. Reheat them on a low-heat grill or in a skillet for 2–3 minutes per side, adding a fresh slice of sharp cheddar at the end to bring back that melty, juicy texture for quick weekday meals.
16.Can I freeze pre-formed raw Impossible patties for future cookouts?
Absolutely! Stack formed, unsalted patties between parchment squares, seal them in a freezer-safe bag, and freeze for up to 3 months. You can grill them straight from frozen—just add 2 minutes of cook time per side, and salt them right as you put them on the grill for the best juicy texture.
17.Do I need to let cooked Impossible patties rest like I do with beef burgers?
Yes, let the cooked, cheese-topped patties rest for 2 minutes after you pull them off the grill, just like you would with beef. This lets the juicy, flavorful fat redistribute through the patty instead of running all over your plate the second you take a bite, for a perfect, moist bite every time.

OMG, this Juicy Grilled Impossible Burger was such a game changer for our weekend cookout! I was worried the plant-based patties would dry out on the grill like the last brand I tried, but these stayed so juicy even my meat-obsessed teen went back for seconds. Topped them with dill pickles, melted vegan cheddar, and a quick special sauce, and half our guests didn’t even realize it wasn’t beef! 10/10 will be making these for our next neighborhood potluck too.

Wait quick question—did you oil your grates first? I tried grilling Impossible patties last month and they stuck so bad I lost half a patty to the grill grates, total bummer 😭

Great question, Jake! I always recommend giving grill grates a light coat of high-smoke-point oil (avocado or canola works perfectly) right before adding the patties, and resist the urge to flip them too early! Wait 4-5 minutes per side and they’ll release easily with zero sticking. So happy the recipe was a hit at your cookout, Liz!

Super easy recipe that’s perfect for my weekly meal prep! Total cook time was right around 30 minutes just like the recipe said, which is ideal for busy weeknights when I don’t have a ton of time to cook. I grilled up four patties on Sunday, stored them in the fridge, and they reheated beautifully in the air fryer after work all week. No sad, dry veggie burgers here—they stayed SO juicy! The only small tweak I made was adding a pinch of extra smoked paprika to the patties for a deeper, smokier flavor. Already added this to my regular meal rotation.

Love the smoked paprika tweak, Mike! That’s such a smart addition to amp up that grilled, smoky flavor even when you’re reheating patties mid-week. So glad this easy recipe fits right into your meal prep routine!

Made these last night for our casual family dinner and my kids loved it! My 7-year-old is ridiculously picky and usually turns up her nose at anything labeled plant-based, but she ate her entire burger in 10 minutes flat and asked if we could have “those yummy burgers” again next week. I’m still pretty new to grilling so I was nervous I’d mess them up, but the easy difficulty rating was no joke—no fancy steps, no weird ingredients, just straight-up good food. We served ours with grilled corn on the cob and creamy potato salad on the side, total summer perfection.
