How to Make Your Melty Burgers
- Mix Up the Secret Sauce
- Combine mayo, ketchup, chopped pickles and Worcestershire sauce in a bowl. Stir well and set aside.

- Split the beef into 4 equal portions and shape into thin patties. Season with salt and pepper.
- Cook the Beef
- Using the same pan, cook patties for 3-4 minutes per side on medium-high heat. Set aside when done.
- Build Your Sandwiches
- Lay bread slices butter-side down. Layer Swiss cheese, beef patty, caramelized onions, cheddar, then top with another bread slice, butter-side up.
- Toast Until Golden
- Cook each sandwich for 2-3 minutes on each side until the bread turns golden and cheese gets all melty.

Tasty Twists and Serving Ideas
Try ground turkey or plant-based patties for a lighter option. Switch things up with pepper jack or provolone cheese if you want. Pair with french fries, coleslaw or a green salad for a complete meal. Whatever you do, don't skip the secret sauce, it really makes the whole thing special!
