Ingredients
Method
Step 1 — Mix your spice blend
- Combine cumin, smoked paprika, allspice, coriander, garlic powder, cinnamon, salt, and pepper in a small bowl. Set aside. You will press this into the patties right before smashing rather than mixing it into the beef which keeps the meat loose and gives you better texture.
Step 2 — Prep your toppings
- Soak your sliced red onion in cold water for 10 minutes. This removes the harsh raw bite and leaves you with onion that is pleasantly mild and slightly sweet. Drain and pat dry. Toast your buns in a dry pan until golden. Set everything out and ready because smash burgers move fast once you start cooking.
Step 3 — Heat your cast iron
- This is the most important step. Heat your cast iron on high for at least 3 full minutes before anything touches it. You want it screaming hot. Drop a tiny piece of beef in and it should sear immediately on contact. If it sizzles gently the pan is not hot enough. Keep going.
Step 4 — Smash the burgers
- Divide your beef into 4 equal loose balls. Do not pack them tight. Place one ball in the center of the hot cast iron and immediately press it flat with a heavy spatula, a burger press, or even the bottom of a heavy pot. Press hard and hold for 10 seconds. Sprinkle a generous pinch of your shawarma spice blend directly onto the top of the smashed patty. Cook for 90 seconds without touching it. The edges should be deeply browned and lacy. Flip once, immediately add cheese, and cook for another 30 seconds. Remove and repeat.
Step 5 — Build the burger
- Spread a generous layer of toum on both sides of the toasted bun. Add shredded lettuce on the bottom. Place the cheesy smash patty on top. Add pickles and soaked red onion. Drizzle pomegranate molasses over the patty before closing the bun. Add hot sauce if you want heat.
Notes
Mix your shawarma spice blend in a larger batch and store it in a jar. It keeps for months and you will find yourself putting it on everything from roasted vegetables to grilled chicken. Having it ready means this burger goes from fridge to table in about 15 minutes on a weeknight.
