With a basic recipe for toaster oven grilled cheese and this gourmet-style apple and Havarti grilled cheese, do you really need more cheese sandwich recipes? The short answer: Yes!

This recipe is made a little differently from those other toaster oven grilled cheeses. It uses the TOAST setting so there’s no stopping to flip the sandwich.

Plus, toasting the bread and cheese first helps to keep the juicy tomato slices from making things soggy. This way you end up with a sandwich that’s the perfect combo of gooey, toasty, fresh, and tasty.

Ingredient Notes

Mayo: It’s fantastic at turning bread golden and toasted. Plus you don’t have to wait for it to soften like butter. But if you don’t like mayo, butter works too.

Small Tomato: Use the best, reddest, freshest tomato you can find.

Balsamic Glaze: It’s thick, tangy, sweet, and tastes delicious drizzled on any vegetable but especially on fresh tomatoes. Balsamic glaze can be found at most major grocery stores on the oil and vinegar aisle. If you want to try making your own, check out this easy Balsamic Glaze Recipe from Rachel Cooks.

Step-By-Step Instructions

1. Start by spreading two pieces of bread with a little mayo on one side. Flip the pieces over and top each of the dry sides with a slice of cheese.

Yummy Reader Recommendation: for an extra pop of flavor, spread the bread with pesto before adding the cheese.

2. Next, place the bread side-by-side on the rack in your toaster oven. Set the machine to TOAST and cook until the cheese is melted and the bread is toasted about 4 to 5 minutes.

3. Let the cheesy toast cool for a few minutes while you slice the basil and tomatoes.

5. Top with the remaining cheesy toast and dig in!

Baked Cheese and Tomato Sandwich

This Toasted Caprese Sandwich Recipe works best in a traditional old-school toaster oven.

If your oven doesn’t have a TOAST setting or you’ve got one with “smart toasting technology” (like our Breville Smart Oven Pro BOV845BSS) you can use the BAKE setting instead. This method is very similar to our toaster oven baked grilled cheese recipe.

  1. Use the bottom rack placement and preheat to 400°F on the BAKE setting.
  2. Prep the bread and cheese as directed but place the slices on a baking sheet. 
  3. Cook until the bottom of the bread is golden and toasted, about 6 to 7 minutes. If the bread is toasted but the cheese is not melted enough, switch to the BROIL setting for 1 to 2 minutes. 
  4. Top your toasted cheesy bread with the basil, tomato, and balsamic glaze, and dig in!

To prepare using the BAKE setting:

  1. Preheat the toaster oven to 400°F.
  2. Follow the instructions for preparing the bread and cheese and place the slices on a baking sheet. 
  3. Cook until the bottom of the bread is golden and toasted, about 6 to 7 minutes. If the cheese is not melted enough, broil for 1 to 2 minutes. 
  4. Top with the basil and tomato, and enjoy!

To make this sandwich in our Breville Smart Oven Pro Countertop Oven we used the TOAST function with a Darkness Level of 5 or 6 and a Slices Setting of 4.

  1. I spread pesto sauce lightly on bread, then add cheese and tomato slices. Then toast as you do!

    1. YUM Nikki!! The pesto sounds fantastic and is an especially good option if you don’t have fresh basil. Thanks for sharing!
