Serve Immediately: The crispiness is at its peak right out of the oven. Pair with tomato soup or a simple green salad.
To Store: Wrap leftovers in foil and refrigerate for up to 2 days.
To Reheat: Re-crisp in a toaster oven or air fryer at 375°F (190°C) for 3–4 minutes—never the microwave (it’ll go soggy).
Variations:
Garlic Butter Bliss: Add a pinch of garlic powder and dried parsley to your butter mix.
Spicy Kick: Layer in a few jalapeño slices or a dash of hot sauce.
Breakfast Twist: Add a fried egg and crispy bacon between the cheese layers.
Italian Style: Use mozzarella, basil, and a touch of marinara for a pizza-inspired version.
FAQ:
Q: Can I make this in a toaster oven?
Absolutely! Follow the same steps—just keep an eye on the cooking time, as toaster ovens may brown faster.
Q: What’s the best cheese for maximum melt?
Cheddar, American, or fontina melt beautifully. For an extra stretch, mix mozzarella and cheddar.
Q: Can I use vegan ingredients?
Yes! Use dairy-free butter and vegan cheese slices. They’ll crisp and melt similarly when baked.
Q: Why use mayonnaise?
Mayo has a higher smoke point than butter, which helps achieve that deep golden crust without burning—especially in the oven.
