When summer tomatoes are at their peak, it only takes a few ingredients to turn them into something spectacular. These Cheesy Margherita Tomato Slices are bursting with flavor and couldn’t be easier to make. If you love the flavors of a classic Margherita pizza—juicy tomatoes, gooey mozzarella, fragrant Italian herbs—you’ll swoon for this lighter, crust-free version. They’re low-carb, gluten-free, and totally crave-worthy (112 calories per slice, with 8g fat, 2.8g carb and 7.1g protein).
Simple Ingredients, Big Flavor
You’ll only need a handful of staples to bring this dish together:
- Ripe beefsteak tomatoes*
- Fresh mozzarella cheese
- Olive oil
- Dried Italian herbs (I’m a fan of this freeze-dried Italian blend)
- Salt and pepper
That’s it! No fancy prep, no dough to roll out—just slice, layer, and air fry or bake. In about 10 minutes, you’ll have bubbly, golden, cheesy tomato slices that work as a side dish, appetizer, or even a fun party snack for summer entertaining.

No Beefsteak? No Problem.
While thick-sliced beefsteak tomatoes are ideal for holding that gooey mozzarella topping, smaller tomatoes like Romas or large slicing tomatoes also work beautifully. Just adjust the size of your cheese slices to match.

How to Cook these Cheesy Tomato Slices
This recipe is super versatile—you can use your air fryer for faster cooking (and less heat in the kitchen!) or pop them in the oven. I LOVE my air fryer (this one) and use it multiple times per day for quick, easy meals and healthy recipes like this!
