Ingredients for Baked Ratatouille Tomatoes Zucchini
This beautiful tomatoes zucchini eggplant ratatouille bake comes together with simple, fresh ingredients. Here’s what you’ll need:
- 2 medium zucchinis, sliced into 1/8 to 1/4-inch rounds – choose firm ones for best structure
- 2 medium yellow squash, sliced into 1/8 to 1/4-inch rounds (optional) – adds another layer of color and flavor
- 2 medium eggplants, thinly sliced – salting and patting dry helps reduce bitterness
- 4-5 ripe Roma tomatoes, sliced – Romas hold their shape well when baked
- 1 medium onion, finely diced – forms the savory base
- 3 cloves garlic, minced – essential for that classic ratatouille aroma
- 2 tablespoons olive oil, plus more for drizzling – good quality olive oil makes a difference
- 1 tablespoon tomato paste – concentrates the tomato flavor
- 1/4 cup crushed tomatoes or canned tomato sauce – adds moisture to the base
- 1 teaspoon dried oregano – classic Mediterranean herb
- Salt and freshly ground black pepper, to taste – season generously
- Fresh thyme leaves, a few sprigs – adds a lovely, earthy fragrance
- Fresh basil leaves, for garnish – brightens the finished dish
- 1/4 teaspoon red pepper flakes (optional) – for a hint of heat
How to Make Baked Ratatouille Tomatoes Zucchini
- Step 1: Preheat your oven to 375°F (190°C). This ensures a nice, even bake for our vegetable medley.
- Step 2: In a skillet over medium heat, heat 1 tablespoon of olive oil. Sauté the diced onion until it becomes translucent and fragrant. Then, stir in the minced garlic, tomato paste, and crushed tomatoes or sauce. Season this base with salt, pepper, and oregano. Let it simmer for about 5–7 minutes until it thickens slightly, creating a rich sauce. Spread this evenly at the bottom of your 9×13-inch baking dish.
- Step 3: Now comes the artful part of this oven-baked ratatouille! Using a sharp knife or a mandoline slicer, carefully slice the zucchini, yellow squash (if using), eggplant, and tomatoes into thin, even rounds, about 1/8 to 1/4 inch thick. If your eggplant seems a bit bitter, a pro tip is to sprinkle the slices with salt and let them sit for 10–15 minutes, then gently pat them dry with paper towels.
- Step 4: Arrange the sliced vegetables over the tomato-onion base in a beautiful, alternating pattern. I like to go tomato, zucchini, yellow squash, eggplant, and then repeat. Try to keep the slices standing upright and slightly overlapping each other. This layering is key to the visual appeal of our baked ratatouille tomatoes zucchini.
- Step 5: Drizzle the assembled vegetables generously with the remaining olive oil. Sprinkle everything with salt, freshly ground black pepper, a few sprigs of fresh thyme, and red pepper flakes if you like a little warmth.
- Step 6: Cover the baking dish tightly with aluminum foil. This traps the steam and helps the vegetables cook through evenly. Bake it in the preheated oven for 35 minutes.
- Step 7: After 35 minutes, carefully remove the foil. You’ll notice the vegetables are starting to soften. Continue baking the oven-baked ratatouille uncovered for another 20–25 minutes, or until the tops of the vegetables are lightly golden brown and tender when pierced with a fork.
- Step 8: Let this gorgeous baked ratatouille tomatoes zucchini rest for 5–10 minutes before serving. This resting period allows the flavors to meld beautifully and makes it easier to serve. Garnish with fresh basil leaves just before presenting it to your guests.
