Ingredient Checklist


Instructions Checklist
  • In a 10- to 12-inch frying pan over medium-high heat, frequently stir onions and 1 tablespoon olive oil until onions begin to brown, 12 to 15 minutes. Season to taste with salt and pepper.

  • Meanwhile, rinse tomatoes, core, cut in half, and squeeze out seeds. Thinly slice tomatoes crosswise.

  • Combine basil, thyme, and garlic. Mix 1/2 of the herbs with zucchini.

  • Spread cooked onions in a shallow 2- to 3-quart casserole. Distribute zucchini evenly over onions.

  • Layer tomato slices over sliced zucchini. Sprinkle evenly with remaining herb mixture and lightly with salt and pepper. Drizzle vegetables with remaining olive oil.

  • Bake in a 400° oven until tomatoes are browned and zucchini slices are tender when pierced, 35 to 40 minutes (30 to 35 minutes in a convection oven). Add salt and pepper to taste.
