Smashed Burgers

[The Smash Into Mouth Recipe]

These ultra-thin, lacy-edged smash burgers deliver the crispiest crust you’ve ever pulled off a home griddle — beefy, caramelized, and done in minutes. Stack two patties on a grain-free bun with all the fixings for a weeknight dinner that absolutely slaps without the guilt spiral.

Ingredients

For the Patties:
2 lbs (900g) 80/20 ground beef (grass-fed preferred)
1 tsp (5g) Diamond Crystal kosher salt (or pink Himalayan)
1/2 tsp (2.5g) black pepper, freshly cracked
1/2 tsp (2.5g) garlic powder
2 tbsp (30ml) avocado oil

For the Smash Sauce:
1/3 cup (80ml) avocado oil mayonnaise
2 tbsp (30ml) sugar-free ketchup (or no-sugar-added)
1 tbsp (15ml) yellow mustard
1 tbsp (15ml) dill pickle brine
1 tsp (5ml) coconut aminos
1/2 tsp (2.5g) smoked paprika
1/4 tsp (1.25g) garlic powder

For Assembly:
4 grain-free burger buns (cassava flour-based preferred) or lettuce wraps
8 slices grass-fed cheddar or American-style cheese
1 cup (50g) shredded iceberg lettuce
1 large tomato, thinly sliced
1/2 white onion, very thinly sliced
Dill pickle chips, to taste
1 tbsp (15ml) avocado oil (for toasting buns)

Steps

Prep:

Divide ground beef into 8 equal loose balls, about 4 oz (113g) each. Do not overwork or compact the meat — keeping it loose is what creates those signature craggly, lacy edges when smashed. Season the tops of each ball generously with salt, pepper, and garlic powder. Make the smash sauce by whisking together mayo, ketchup, mustard, pickle brine, coconut aminos, paprika, and garlic powder in a small bowl. Refrigerate until ready to use.

Heat:

Heat a cast iron skillet or flat griddle over high heat for 3-4 minutes until screaming hot — a drop of water should evaporate instantly. Add 1 tbsp (15ml) avocado oil and swirl to coat. The pan must be ripping hot to achieve proper Maillard crust; medium heat will steam the burgers instead of searing them.

Smash:

Place 2-3 beef balls in the pan seasoned-side down. Immediately place a sheet of parchment paper over each ball and press straight down firmly with a heavy spatula, burger press, or the bottom of a small saucepan — smash hard and fast within the first 10 seconds of contact. Hold pressure for 5-10 seconds until patty is about 1/4 inch (6mm) thin. Peel off parchment. Cook undisturbed for 2-2.5 minutes until the edges are deeply browned and lacy.

Flip and Cheese:

Flip each patty with a thin metal spatula, scraping up all the crust from the pan — don’t leave any of that behind. Immediately lay one slice of cheese on each patty. Cook for 60-90 seconds more until cheese is melted and the second side has a good sear. For a double smash burger, stack one cheesy patty on top of another while still in the pan and let them fuse for 15 seconds. Remove and repeat with remaining beef balls.

Toast:

Wipe the pan quickly with a paper towel. Add the remaining avocado oil and toast bun halves cut-side down over medium heat for 60-90 seconds until golden. This step is non-negotiable — a toasted bun stands up to the sauce and juicy patties without collapsing.

Build and Serve:

Spread smash sauce generously on both bun halves. Layer from bottom up: bottom bun, pickles, raw onion slices, double smash patty stack, tomato, shredded lettuce, more sauce, top bun. Serve immediately — smash burgers wait for no one.


Make it Good For The Gut

Swap the standard pickle chips for naturally fermented dill pickles (refrigerator section, brine should be cloudy) to add live probiotic cultures right into every bite. Add a generous smear of raw sauerkraut on the bottom bun alongside the pickles — it pairs beautifully with the smash sauce and brings billions of beneficial bacteria. Use grass-fed beef for a significantly better omega-3 to omega-6 ratio compared to conventional, which helps reduce systemic inflammation. A lettuce wrap instead of a bun eliminates any grain exposure entirely and adds prebiotic fiber. The coconut aminos in the smash sauce keeps it soy-free and gut-friendly without sacrificing any of that savory depth.

Remix Options

Lettuce Wrap: Ditch the bun entirely and wrap the double stack in large, cold iceberg or butter lettuce leaves — the crunch contrast against the hot patty is genuinely excellent. Mushroom Swiss: Swap cheddar for grass-fed Swiss and top each patty with 1/4 cup (25g) of thinly sliced cremini mushrooms sauteed in grass-fed butter with a pinch of fresh thyme — deglaze the mushrooms with 1 tsp (5ml) coconut aminos for depth. Smash Melt: Build the burger open-faced on toasted cassava sourdough instead of a bun, double the cheese, and finish under the broiler for 60 seconds until bubbling. Spicy Smash: Add 1 tsp (5ml) hot sauce and 1/2 tsp (2.5g) cayenne to the smash sauce, and press a thin slice of fresh jalapeno directly into each patty before smashing so it sears into the crust. Turkey Smash: Use 93/7 ground turkey in place of beef — the technique works beautifully, though turkey benefits from a full minute extra per side and should reach 165°F (74°C) internal. Add 1 tsp (5ml) Worcestershire-style coconut aminos to each ball for depth since turkey has less inherent fat flavor. Budget-Friendly: Conventional 80/20 ground beef delivers outstanding smash burger results at a fraction of the cost — the high-heat technique actually shines with standard beef. Save the grass-fed for recipes where it’s eaten raw or barely cooked.

Good To Know

Why 80/20: Fat content is everything in a smash burger. The fat renders rapidly on the screaming-hot pan, basting the crust from underneath as it cooks and creating those distinctive crispy, lacy edges. Leaner beef (90/10 or above) dries out too fast and won’t develop the same caramelization. The 10-Second Rule: You must smash within the first 10 seconds of the beef hitting the pan — once the exterior proteins start to set, the patty won’t compress properly and you lose the signature texture. Have your parchment and press ready before the beef goes down. Pan Choice: Cast iron or a carbon steel griddle are ideal for their heat retention and even distribution. Stainless works. Non-stick is acceptable but won’t build as dark a crust and can be damaged by the high heat required. Never use a thin aluminum pan — it hot spots badly. Loose Balls Only: Resist any urge to compress the beef when portioning. The irregular texture of a loosely packed ball creates craggy surface area — when smashed, those crevices become ultra-crispy bits. A tightly packed ball smashes into a uniform disc with far less character. Cheese Timing: Adding cheese immediately after the flip and covering the pan with a lid or aluminum foil tent for 30 seconds creates a steam effect that melts the cheese perfectly without overcooking the patty. Batch Cooking: Cook in batches of 2-3 patties max to avoid crowding the pan and dropping the surface temperature. A crowded pan steams rather than sears. Between batches, let the pan reheat for 60 seconds. Storage: Smash burgers are best eaten immediately — the crust softens quickly as the patty rests. Cooked patties can be refrigerated for up to 3 days and reheated in a dry cast iron skillet over high heat for 60-90 seconds per side to re-crisp. Do not microwave. Make-Ahead: Portion and loosely ball the beef up to 24 hours ahead; refrigerate uncovered on a parchment-lined tray. Cold beef actually smashes better — warmer beef softens faster and can stick. Pull from fridge 10 minutes before cooking. Freezing: Freeze raw balls on a parchment-lined sheet until solid (about 2 hours), then transfer to a zip bag for up to 3 months. Cook from frozen adding 1 extra minute per side.
