Description
A cozy, diner-style sandwich featuring a juicy beef patty, gooey Swiss cheese, and sweet caramelized onions, all grilled between buttery slices of bread for the ultimate comfort-food experience.
Ingredients
- 1 sweet yellow onion, thinly sliced
- 2 tablespoons butter, divided
- 1 tablespoon apple cider vinegar
- 8 ounces 90/10 ground beef
- ¼ teaspoon salt
- ¼ teaspoon black pepper
- 4 slices sandwich bread (rye, sourdough, or white)
- 4 slices Swiss cheese
- Optional: mustard
Instructions
- In a large skillet over medium heat, melt 1 tablespoon butter and add sliced onion. Cook, stirring occasionally, about 25 minutes until deep brown. Add vinegar during the last 5 minutes, stir, and remove onions.
- Shape beef into two thin patties about the size of your bread. Season with salt and pepper. In the same skillet on medium-high, cook patties 3 minutes per side until done. Remove.
- Wipe skillet clean. Melt remaining butter, then butter one side of all bread slices in the skillet. Remove two slices for assembly.
- Place two remaining buttered-side-down slices in the skillet. Add Swiss cheese, patty, caramelized onions, then another slice of Swiss. Top with second bread slice, butter side up.
- Grill over medium-low heat for 3–4 minutes per side, flipping once, until bread is golden and cheese melts. Slice in half and serve hot.
Notes
- You can prep onions and patties a day ahead for quicker assembly.
- Try different cheeses like provolone or cheddar for variation.
- Grill on medium-low to prevent burning and ensure thorough melting.
- To reheat, warm assembled sandwich in a 350 °F oven for 8–10 minutes.
