Instructions:
Step 1: Make the Secret Sauce
In a small bowl, whisk together:

- Sugar
- Relish
Refrigerate until ready to assemble the sandwiches.
Step 2: Season & Shape the Patties
In a large bowl, gently mix:

Do not overmix —this keeps the patties tender.
Divide into 6 equal portions and shape into oval patties (about ½ inch thick).
Step 3: Cook the Onions
Melt the butter in a skillet over medium heat .
Add onion slices and cook, stirring occasionally, until soft and golden brown (10–12 minutes ).
Set aside while cooking patties.
Step 4: Brown the Beef Patties
Heat a clean skillet or griddle over medium-high heat .
Cook each patty for 2 minutes per side , or until browned and just cooked through (160°F internal temp ). Don’t overcook—keep them juicy!
Step 5: Assemble the Sandwiches
Butter the outer sides of the rye bread slices.
Layer inside:
- 1 tbsp secret sauce
- 3 tbsp caramelized onions
- 1 slice cheddar cheese
- 1 beef patty
- 1 slice Swiss cheese
- More onions and secret sauce
Close the sandwich and press lightly.
Step 6: Grill Until Golden
Place sandwiches in the skillet over medium heat .
Cook for 2–3 minutes per side , pressing gently with a spatula until golden and crispy.
Step 7: Serve Hot & Hearty
Transfer to a cutting board and let rest for 2 minutes before slicing.
Serve warm with:
- Pickles
- Coleslaw
- Or a side of crispy fries
Each bite brings together:
- Juicy, savory beef patty
