How to Store and Freeze Your Reuben Sandwiches
- Allow the corned beef to cool completely before storing. This helps maintain its texture and flavor.
- Wrap each sandwich individually in plastic wrap or aluminum foil to prevent them from drying out and to keep them fresh.
- Place the wrapped sandwiches in an airtight container or a resealable plastic bag. This will help to keep them from absorbing any unwanted odors from the refrigerator.
- Store the sandwiches in the refrigerator for up to 3 days. If you plan to keep them longer, freezing is a better option.
- To freeze, wrap each sandwich tightly in plastic wrap, then again in aluminum foil. This double wrapping helps to prevent freezer burn.
- Label each package with the date so you can keep track of how long they’ve been stored.
- Place the wrapped sandwiches in a single layer on a baking sheet and freeze until solid. This prevents them from sticking together.
- Once frozen, transfer the sandwiches to a large resealable freezer bag or an airtight container. They can be stored in the freezer for up to 2 months.
- When ready to eat, thaw the sandwiches in the refrigerator overnight.
- Reheat in a skillet over medium heat, grilling until the bread is golden brown and the swiss cheese is melted, about 3-4 minutes per side. Alternatively, you can reheat them in a preheated oven at 350°F (175°C) for about 10-15 minutes, or until heated through.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Wrap each sandwich in aluminum foil to retain moisture. Place them on a baking sheet and heat for about 15-20 minutes or until the cheese is melted and the bread is crispy.
For a quicker method, use a skillet. Heat the skillet over medium heat and place the sandwiches in the skillet. Cover with a lid to help the cheese melt evenly. Heat for about 3-4 minutes per side, until the bread is golden brown and the cheese is melted.
If you have an air fryer, preheat it to 350°F (175°C). Place the sandwiches in the air fryer basket and heat for about 5-7 minutes, flipping halfway through, until the bread is crispy and the cheese is melted.
For a microwave option, place the sandwich on a microwave-safe plate. Cover with a damp paper towel to prevent the bread from drying out. Microwave on high for about 1-2 minutes, checking halfway through to ensure the cheese is melting evenly.
To use a toaster oven, preheat it to 350°F (175°C). Place the sandwiches directly on the rack or on a baking sheet. Heat for about 10-15 minutes, until the bread is crispy and the cheese is melted.
