2 sweet onions (about 1 lb. total), such as Walla Walla or Oso, peeled and thinly sliced
3 cloves garlic, peeled and minced
2 pounds ripe tomatoes, rinsed, cored, and sliced (1/4 in. thick)
1/3 cup chopped fresh basil
3 tablespoons chopped fresh oregano leaves
Salt and pepper
4 slices crusty artisan-style bread (each about 1 in. thick and 3 by 5 in.), cut into chunks
1/4 cup (1/8 lb.) butter
1/2 cup grated parmesan cheese
How to Make It
Heat oil in a 10- to 12-inch frying pan over medium heat. When hot, add onions and garlic. Stir frequently until onions are limp and beginning to brown, about 6 minutes. Pour into a 2- to 3-quart baking dish with sides at least 2 inches high, and spread onions level. Top evenly with tomato slices, basil, and oregano. Sprinkle generously with salt and pepper.
In a food processor, whirl bread with butter and cheese until mixture forms coarse crumbs. Sprinkle evenly over tomatoes.
Bake in a 350° oven until topping is golden brown and juices are bubbling, 20 to 25 minutes. Cool 5 minutes and serve warm.
I used an artisan french bread for my topping and the dish turned out so heavenly, I had to make it again! I highly recommend using the fresh herbs called for, but if you have to substitute with dry, I'm sure you could and would still taste yummy.
