Fresh Tomato Gratin

If you’re looking for a good tomato-forward recipe, this Fresh Tomato Gratin is a keeper. It has an unforgettable, delicious, savory roasted tomato flavor, and it pops with color.

Instead of topping fresh tomatoes with bread cubes or bread crumbs this recipe calls for tossing crispy cubes of bread with a savory cream mixture to form a base for rows of colorful tomatoes.

Preparing the Bread

Buy a large loaf of Italian bread and use a 9-3/4″ Slicer to easily cut it into cubes. The knife’s long, sharp blade is designed to slice bread without crushing it.

Toss the cubes into a large skillet with olive oil to toast them with some Italian seasoning. Keep a close eye on the bread cubes when browning because they can go from golden brown to burnt very quickly.

Once the bread cubes are toasted, toss them into a bowl and mix them with heavy cream, Romano cheese, garlic, red wine vinegar, fresh basil, salt and pepper. Using a large Slotted Spoon, spread the cubes evenly in the baking dish to form a nice base for layering on the tomatoes.

Preparing the Tomatoes

Heirloom tomatoes are recommended for this gratin but if they are not available use any type of red, yellow and orange tomatoes.

To easily slice them use a sharp utility knife, like the Trimmer or Santoku-Style Trimmer. The Double-D® edges on these knives cut through tomatoes without squishing them.

You can also try using Cutco’s Traditional Cheese Knife, which many customers say works like a dream for slicing tomatoes.

Layer the sliced tomatoes on the bread mixture and alternate the colors in the rows to create an eye-catching presentation.

As the gratin bakes, the bread soaks up the juicy goodness from the tomatoes.

For this Fresh Tomato Gratin, I had some help in the kitchen from my oldest son, Mark, who was visiting from Denver. I think he was just hanging around until it was done so he could eat it.

It smelled wonderful as it baked and I couldn’t wait to cut it. The sweetness of the tomatoes and saltiness of the cheese combined with the seasoned bread cubes is so good.

This one got rave reviews from my son and everyone else who tried it.
