How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover Welsh rarebit on a baking sheet and cover it loosely with aluminum foil. Bake for about 10-15 minutes or until the cheese sauce is bubbly and the bread is heated through.
For a quicker method, use a toaster oven. Set it to 350°F (175°C) and place the Welsh rarebit inside. Heat for about 8-10 minutes, checking frequently to ensure the cheese sauce doesn't overcook.
If you're in a hurry, the microwave can be your friend. Place the Welsh rarebit on a microwave-safe plate. Cover with a microwave-safe lid or another plate to prevent splattering. Heat on medium power for 1-2 minutes, checking halfway through to ensure even heating.
For a stovetop method, heat a non-stick skillet over medium-low heat. Place the Welsh rarebit in the skillet and cover with a lid. Heat for about 5-7 minutes, or until the cheese sauce is melted and the bread is warmed through. This method helps maintain a crispy texture on the bottom of the bread.
If you have an air fryer, preheat it to 320°F (160°C). Place the Welsh rarebit in the basket and heat for about 5-7 minutes. This method will give you a crispy finish while ensuring the cheese sauce is perfectly reheated.
