Stuffed Burgers
The recipe calls for mixing the ground beef and hamburger seasoning in a large bowl. If desired, you can divide the beef and seasoning between 2 bowls for easier mixing. Be careful not to overmix the ingredients, as this can produce an unpleasantly dense burger.
Ingredients:
Burger filling options (choose one):
- 4 bacon slices, cooked until crispy and crumbled
- 2 oz. blue cheese, crumbled
- 3 oz. feta cheese, crumbled
- Zest of 1/2 lemon
- 1 1/2 tsp. minced fresh oregano
- 2 oz. feta cheese, crumbled
- 1 small yellow onion, diced and caramelized
- 2 oz. Roquefort cheese, crumbled
- 1 small yellow onion, diced and caramelized
For the burgers:
- 2 1/4 lb. ground beef
- 5 Tbs. hamburger seasoning
- 1 large red onion, sliced 1/4 inch thick
- Olive oil as needed
- 6 hamburger buns
- Mayonnaise for serving
- Lettuce leaves for serving
- 6 tomato slices
Directions:
Place the ground beef in a large bowl and sprinkle with the hamburger seasoning. Using your hands, gently mix the ingredients together; do not overmix.
Divide the beef into 6 equal portions and shape each into a ball. Using your thumb, make a deep depression in each ball; do not push all the way through. Spoon about 1 Tbs. of the filling mixture into the depression. Gently shape the meat around the filling, sealing it inside. Using a burger press according to the manufacturer's instructions, or using your hands, form the balls into patties about 1 inch thick. Transfer the patties to a flexible easy-turn grill basket and set aside.
Put the red onion slices in a shallow bowl and toss with enough olive oil to lightly coat. Arrange on a nonstick grill topper. Set aside.
Prepare a medium-hot fire in a grill.
Place the grill topper on the grill. Cook, turning the onion slices once, until softened and slightly caramelized, 10 to 15 minutes total. Transfer to a plate and cover loosely with aluminum foil.
Place the burgers on the grill and cook, turning once, 5 to 7 minutes per side for medium, or until done to your liking.
Transfer each burger to the bottom half of a bun. Spread mayonnaise on the inside of each top bun. Top each burger with grilled onion slices, lettuce and tomatoes. Serve immediately. Serves 6.
