Tomato Au Gratin Recipe That Tastes Incredible

This Tomato Au Gratin is awesome! A family member dropped off a big box of fresh tomatoes right before I left town for a week. What was I to do? These ruby globes were destined to go to waste. So I did what any good chef would do, I got creative!

I made a single serving to start, with just two tomatoes a garlic clove and 2 tablespoons of both cheese and bread crumbs I had a delicious and filling lunch for one. I loved this Tomato Au Gratin recipe so much I made a large casserole for my family to serve with dinner that night, both ways are equally easy and delicious.

Makes 6 Tomato Au Gratin servings.


  • 8 firm tomatoes
  • 3 garlic cloves sliced into thin coins
  • 1/2 cup Panko bread crumbs
  • 1/2 cup sharp cheddar cheese finely grated
  • 1 teaspoon Extra Virgin Olive Oil
  • Salt and pepper to taste
  • Fresh basil leaves (optional)

Get started:

Tomato Au Gratin Recipe– Slice the tomatoes into 1/4 inch thick disks.

– In a 9 by 9 casserole dish layer 1/2 of the tomatoes, slightly overlapping on the bottom of the dish.

– Cover with 1/3 the cheese, then 1/2 the Panko bread crumbs and 1/2 the garlic slices.

– Add the remaining tomatoes, slightly overlapping in a thick layer.

– Top with 1/3 cheese, the remaining  garlic and Panko crumbs. Top off with the remaining cheese and drizzle with olive oil.

– Place in the oven and then turn on the oven to 450 degrees. Bake for 15 minutes, then if needed place under the broiler for a minute or two to crisp up.

– Remove from the oven and let cool for 5 minutes before cutting into or salting.
