Ingredients
- 1 pound ground beef 80/20 recommended
- 8 slices rye bread
- 1 large yellow onion thinly sliced
- 8 slices Swiss cheese
- 2 tablespoons butter softened
- 2 tablespoons mayonnaise optional, for spreading on the outside of the bread instead of butter
- 1 teaspoon olive oil
- 1 teaspoon garlic powder
- 1 teaspoon salt or to taste
- ½ teaspoon black pepper
- 2 teaspoons Dijon or yellow mustard optional
Instructions
- Caramelize the Onions: Thinly slice the yellow onion. Heat the olive oil in a skillet over medium-low heat. Add the onion and cook, stirring occasionally, for 15–25 minutes until soft and golden brown. Reduce the heat if the onion begins browning too quickly. Set aside.
- Season and Shape the Beef Patties: In a mixing bowl, combine the ground beef, garlic powder, salt, and black pepper. Divide into four thin patties, shaping them to fit the rye bread. Keep the patties slightly wider than the bread because they may shrink during cooking.
- Cook the Beef Patties: Preheat the air fryer to 375°F (190°C), if recommended by your model. Arrange the patties in a single layer and cook for approximately 7–10 minutes, flipping halfway through. Cook ground beef to an internal temperature of 160°F (71°C). Transfer to a plate.
- Assemble the Patty Melts: Spread softened butter or a thin layer of mayonnaise on one side of each slice of rye bread. Place four slices buttered-side down. Spread mustard on the inside, if using, then add Swiss cheese, a cooked beef patty, caramelized onions, and another slice of Swiss cheese. Top with the remaining bread, with the buttered side facing outward.
- Air Fry Until Golden: Place the sandwiches in the air fryer basket in a single layer. Air fry at 350°F (175°C) for 3–5 minutes, carefully flip, and cook for another 2–4 minutes, until the rye bread is golden and crisp and the cheese is melted. Check early because air fryers vary. Let rest for 1–2 minutes, slice, and serve warm.
Notes
- Use rye bread: It provides the classic patty melt flavor and holds the filling well.
- Cook the onions slowly: Allow 15–25 minutes for the onions to become soft and sweet.
- Avoid overcrowding: Cook sandwiches in batches if needed so the bread browns evenly.
- Keep the patties thin: Thin patties fit more comfortably inside the sandwich.
- Check the temperature: Ground beef should reach 160°F (71°C).
- Watch the bread: Air fryers vary, so check the sandwiches early to prevent over-browning.
- Refrigerate leftovers: Store in an airtight container for 3–4 days.
- Reheat for crispness: Air fry at 325–350°F (165–175°C) until heated through. Leftovers should reach 165°F (74°C) when reheated.
