How to Store / Freeze This Recipe
- Allow the patties and caramelized onions to cool completely before storing. This prevents condensation, which can make the bread soggy.
- Wrap each patty melt individually in aluminum foil or plastic wrap to maintain freshness and prevent them from sticking together.
- Place the wrapped patty melts in an airtight container or a resealable plastic bag. This helps to keep them fresh and prevents any unwanted odors from seeping in.
- Store the special sauce separately in a small airtight container. This ensures that the sauce stays fresh and doesn't make the bread soggy.
- For freezing, place the individually wrapped patty melts in a single layer on a baking sheet and freeze until solid. This prevents them from sticking together.
- Once frozen, transfer the patty melts to a resealable freezer bag or airtight container. Label with the date to keep track of their freshness.
- When ready to enjoy, thaw the patty melts in the refrigerator overnight. This ensures even thawing and prevents the bread from becoming too soggy.
- Reheat the patty melts in a skillet over medium heat until the bread is crispy and the cheese is melted. Alternatively, you can reheat them in a preheated oven at 350°F (175°C) for about 10-15 minutes.
- Add the special sauce just before serving to maintain the best texture and flavor.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Wrap each patty melt in aluminum foil to keep it moist. Place them on a baking sheet and heat for about 10-15 minutes, or until warmed through.
For a quicker method, use a skillet. Heat a non-stick skillet over medium heat. Place the patty melt in the skillet, cover with a lid, and cook for about 3-5 minutes on each side, until the bread is crispy and the cheese is melted.
If you prefer using a microwave, place the patty melt on a microwave-safe plate. Cover with a damp paper towel to prevent it from drying out. Microwave on medium power for 1-2 minutes, checking halfway through to ensure even heating.
For an air fryer, preheat to 350°F (175°C). Place the patty melt in the basket and cook for 3-5 minutes, or until the bread is crispy and the cheese is melted.
