Ingredients
  

For the Burgers:

1 lb (450g) ground beef (80/20 blend)

1/2 tsp garlic powder

1/2 tsp onion powder

1/2 tsp salt

1/4 tsp black pepper

4 slices of Swiss cheese (feel free to add more for an extra cheesy indulgence)

1 tbsp Worcestershire sauce

For the Caramelized Onions:

2 large yellow onions, thinly sliced

2 tbsp unsalted butter

1 tbsp olive oil

1 tsp sugar (optional, enhances caramelization)

Salt to taste

For Assembly:

4 burger buns

Fresh lettuce leaves

Sliced tomatoes

Your choice of condiments (e.g., mustard, mayonnaise, ketchup)

Instructions
 

Caramelize the Onions:

    - In a large skillet, combine the unsalted butter and olive oil over medium heat.

      - Once the butter has melted, add the sliced onions along with a pinch of salt. Stir occasionally, cooking until the onions start to soften (approximately 5 minutes).

        - Lower the heat to low, if using, sprinkle in the sugar, and continue to sauté for 25-30 minutes. Stir regularly until the onions turn a rich, golden brown, deepening in flavor. Remove from heat and set aside.

          Prepare the Burger Patties:

            - In a mixing bowl, add the ground beef and blend in the garlic powder, onion powder, Worcestershire sauce, salt, and black pepper. Mix gently until just combined, taking care not to overwork the meat.

              - Divide the mixture into 8 equal portions and shape each portion into a flat patty.

                Stuff the Burgers:

                  - On 4 of the patties, layer a slice or two of Swiss cheese for an indulgent version.

                    - Spoon a generous amount of the caramelized onions over the cheese.

                      - Carefully place the remaining 4 patties on top of the stuffed ones. Pinch the edges tightly to seal in the cheese and onions securely.

                        Cook the Burgers:

                          - Preheat a grill or a skillet over medium-high heat, lightly greasing the surface if necessary.

                            - Grill the stuffed burgers for approximately 5-7 minutes on each side until they are medium-cooked, or adjust the cooking time to achieve your preferred doneness. For well-done burgers, add extra minutes on each side.

                              Assemble the Burgers:

                                - If desired, briefly toast the burger buns on the grill or in a separate skillet while the burgers finish cooking.

                                  - Once the burgers are cooked, place each stuffed burger on the bottom half of a bun. Layer on lettuce, fresh tomato slices, and your favorite condiments. Cap with the top half of the bun.

                                    Serve:

                                      - Relish your heavenly caramelized onion and Swiss stuffed burgers while they’re hot, paired with crispy fries or a refreshing salad on the side!
