Ingredients

1 lb ground beef (80/20 for juiciness)

1 tsp salt

1 tsp black pepper

4 slices American or Swiss cheese

1 large onion, sliced into thick rings

1 tbsp butter

1 tbsp oil

Optional: burger sauce, pickles, mustard

Instructions

Prep the onions:
Heat butter and oil in a skillet over medium heat. Add onion rings in a single layer and cook 5–7 minutes per side until deeply caramelized. Remove and set aside.

Shape the patties:
Divide the beef into 4 equal balls. Flatten gently into thin patties and season both sides with salt and pepper.

Cook the patties:
In the same skillet, sear patties for 2–3 minutes per side until browned. Place cheese slices on each patty and let melt.

Stack it:
Assemble each burger by stacking:
Patty + cheese → another patty + cheese → top with a swirl of caramelized onions.

Serve hot:
Enjoy as is, or pair with burger sauce, pickles, or mustard on the side.

Notes

Use 80/20 ground beef for ideal fat content and juiciness.

Caramelizing onions low and slow gives the best flavor — don’t rush it!

This burger is naturally low-carb and keto-friendly.

Want extra flavor? Add a dab of Dijon or spicy mayo between patties.

For a grilled version, cook patties on a flat-top or cast iron over direct heat.
