Ingredients: 1 lb ground beef; 1 tbsp olive oil; 1 tsp garlic powder; 1 tsp onion powder; 1/2 tsp salt; 1/4 tsp black pepper; 4 hamburger buns; 1 small onion, thinly sliced; 1 tbsp butter; 4 lettuce leaves; 1 tbsp mayonnaise

A rich and flavorful burger featuring a slow-roasted beef patty, crispy fried onions, and fresh lettuce on a toasted bun.

Method

Preheat oven to 275°F (135°C). In a bowl, mix ground beef with olive oil, garlic powder, onion powder, salt, and pepper.
Form the mixture into 4 equal patties and place on a baking sheet lined with parchment paper.
Roast patties in the oven for 20-25 minutes or until they reach 71°C (160°F) throughout.
While patties roast, heat butter in a skillet over medium heat. Add sliced onion and cook until golden brown and crispy, about 5-7 minutes.
Toast the buns and assemble with lettuce, mayonnaise, roasted patty, and crispy onions.
