Heirloom Tomato Gratin

Annacia *


I've found this to be a veggie dish that even the men will eat with a smile. While I've listed this as a side it's very welcome for brunch as well.

How to Make Heirloom Tomato Gratin


  • 1Heat oven to 425°F. Rub the inside of a 2- to 2 ½-qt baking or gratin dish with garlic, then coat with oil.

  • 3Scatter half the onion mixture in the bottom of the prepared dish. Arrange the tomatoes, overlapping slightly, over the onions and season with 1⁄4 tsp each salt and pepper. Repeat.
