The Best Homemade Smash Burger (Ready in 8 Minutes)

The secret to the best homemade smash burger isn't the beef — it's the technique. And the seasoning.

Smashing a beef ball into a screaming-hot cast iron skillet creates hundreds of caramelized contact points that carry flavour in every bite. UNU's garlic, sweet paprika, and oregano lock into that crust the moment it hits the pan. No sugar, no burning, no competing heat — just pure depth that lets the beef speak for itself.

Why UNU Makes the Best Homemade Smash Burger

• Sweet paprika — deepens the Maillard crust without burning at high heat
• Garlic + onion powder — seasoned on the surface before the smash, locked into the crust permanently
• No chili, no cayenne — zero heat that competes with the beef. Clean, deep flavour only
• Zero calories, zero sugar — season aggressively without affecting your macros

Ingredients (2 double smash burgers)

• 400g ground beef (80/20 — fat is non-negotiable)
• 2 tsp UNU Everyday Spice Blend
• 1 small white onion, very thinly sliced
• 4 slices natural yellow cheddar
• 2 brioche buns, toasted
• Caramelized onions, sauce of choice
• Neutral oil or clarified butter

How to Make the Best Homemade Smash Burger

1. Portion loosely. Divide beef into 4 rough balls of ~100g. Do not compact or shape them — loose balls smash flatter and create better lacy edges.
2. Season the surface only. Press a pinch of UNU into one flat side of each ball right before cooking. Do not mix into the meat — you want the spice in the crust, not the interior.
3. Get your cast iron screaming hot. 450°F+ (230°C+) minimum. Add a thin layer of oil. It should smoke the moment it hits the pan.
4. Smash hard and flat. Place a ball seasoned-side down. Lay a few thin raw white onion slices on top. Using a heavy round burger press, smash with maximum force for 10 full seconds — aim for 5–6mm thickness. The onions embed into the patty surface.
5. Do not touch for 90 seconds. The crust releases itself when it's ready. If it sticks, it's not done.
6. Season again, flip once. Sprinkle another pinch of UNU on the cooked top surface. Flip. Immediately place a slice of yellow cheddar. Cook 45 more seconds.
7. Build and eat immediately. Stack two patties per burger. Smash burgers do not wait — eat them the moment they're built.

The Rules That Make the Difference

• 80/20 beef only. Lean beef makes dry, flavourless smash burgers.
• Cast iron must be smoking before anything goes in.
• Natural yellow cheddar melts correctly. Processed orange slices slide off.
• Season surface only — never mix spice into the raw beef.
