Ingredients
- 1.5 lbs, 80/20 lean-to-fat ratio ground beef
- 1 tsp salt
- 1/2 tsp black pepper
- 1 tsp cajun seasoning
- 1/2 cup mayonnaise
- 1 tsp lemon juice
- 1/2 tsp garlic powder
- 1 tsp hot sauce
- 4, toasted burger buns
- 4 lettuce leaves
- 8 slices tomato slices
- 1 small, thinly sliced red onion
Instructions
- Step 1: In a large bowl, combine 1.5 lbs ground beef with 1 tsp salt, 1/2 tsp black pepper, and 1 tsp Cajun seasoning. Mix gently and form into four 6-ounce patties, making a slight indentation in the center of each.
- Step 2: Preheat an open flame grill or grill pan to high heat (about 450°F). Grill the patties for 4-5 minutes per side for medium doneness, flipping once, until a crust forms and internal temperature reaches 160°F.
- Step 3: While the burgers cook, mix 1/2 cup mayonnaise with 1 tsp lemon juice, 1/2 tsp garlic powder, and 1 tsp hot sauce in a small bowl to make the Cajun aioli.
- Step 4: Toast 4 burger buns on the grill until golden, about 1 minute.
- Step 5: Assemble each burger by spreading 1 tbsp Cajun aioli on the bottom bun, topping with a beef patty, 1 lettuce leaf, 2 tomato slices, and some thinly sliced red onion. Cap with the top bun and serve immediately.
