Ingredients
For the sandwich:
- 1 lb (450g) ground beef
- 1 large onion, thinly sliced
- 8 slices of rye bread (or your favorite sandwich bread)
- 4 slices Swiss cheese
- 4 slices cheddar cheese
- Butter (for grilling)
- Salt and pepper to taste
For the secret sauce:
- ½ cup mayonnaise
- 2 tablespoons ketchup
- 1 tablespoon sweet pickle relish
- 1 teaspoon Worcestershire sauce
Step-by-Step Instructions
1. Make the Secret Sauce
In a small bowl, mix together the mayonnaise, ketchup, sweet relish, and Worcestershire sauce. Stir until smooth and creamy. Taste and adjust if needed (add more relish if you like it tangier).
Cover and refrigerate while you prepare the rest. Trust me – this sauce is the MVP!
2. Caramelize the Onions
In a large skillet over medium heat, melt 1 tablespoon of butter. Add the sliced onions and a pinch of salt. Cook slowly, stirring occasionally, for 15–20 minutes until the onions are soft, golden, and sweet. Set aside.
Pro tip: Don’t rush this step. Low and slow caramelization brings out the natural sweetness of the onions.
3. Form and Cook the Beef Patties
Divide the ground beef into 4 equal parts. Flatten each into a thin patty, slightly larger than your bread slices (they shrink as they cook).
Season both sides with salt and pepper.
In the same skillet over medium-high heat, cook the patties for 3–4 minutes per side, or until fully cooked and browned. Remove and set aside.
4. Assemble the Sandwiches
Take 2 slices of bread for each sandwich. Butter one side of each slice – these will be the outsides.
On the unbuttered side of one slice, layer:
- 1 slice Swiss cheese
- 1 cooked beef patty
- A spoonful of caramelized onions
- A spoonful of secret sauce
- 1 slice cheddar cheese
Top with the second slice of bread (buttered side out).
5. Grill to Perfection
Wipe the skillet clean and return to medium heat. Grill each sandwich for 2–3 minutes per side, pressing gently with a spatula until the bread is golden brown and crispy, and the cheese is melted and gooey.
You’ll know it’s perfect when the cheese starts oozing out the sides.
Optional Add-Ons
- Add a slice of tomato or a few pickles for a tangy crunch.
- Want spice? Add a dash of hot sauce to the secret sauce.
- Swap in turkey or chicken if you’re not into beef.
