Step‑by‑Step Instructions for Oven-Roasted Ratatouille
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This ensures that your Oven-Roasted Ratatouille cooks evenly throughout. While the oven warms up, gather your ingredients to create a smooth workflow, setting the stage for a colorful culinary adventure.
Step 2: Prepare the Vegetables
Rinse your large eggplant, zucchini, yellow squash, onion, and Roma tomatoes under running water. Thinly slice each vegetable to about ⅛” to ¼” thick, creating uniform pieces that will roast perfectly together. As you slice, enjoy the vibrant colors and fresh aromas that waft through the kitchen.
Step 3: Make the Tomato Sauce
In a mixing bowl, combine the can of tomato sauce with Italian seasoning, sweet basil, and a teaspoon of salt. Stir well until the seasonings are fully integrated, and the mixture has a delightful aroma. The seasoned tomato sauce will serve as a flavorful base, enhancing every layer of the ratatouille.
Step 4: Assemble the Dish
Spread the prepared tomato sauce evenly in a large baking dish. Use a spatula to ensure the sauce covers the base completely. This step creates a delicious foundation for your vegetable medley, preventing them from sticking as they roast to perfection.
Step 5: Layer the Vegetables
Begin layering your sliced vegetables atop the tomato sauce in a circular pattern, alternating colors for a stunning visual effect. Make sure to pack them closely, showcasing the beauty of your fresh ingredients. Each layer brings the spirit of your Oven-Roasted Ratatouille to life, inviting everyone to dig in.
Step 6: Drizzle and Season
Once your vegetables are beautifully arranged, drizzle olive oil generously over the top. Then, sprinkle a pinch of salt and freshly ground black pepper to taste. This final touch of seasoning enhances the flavors, ensuring that every bite is a savory delight.
Step 7: Bake to Perfection
Place the baking dish in your preheated oven and bake for 55-60 minutes. Keep an eye on the dish as it roasts, looking for bubbling sauce and tender vegetables that are beautifully caramelized. The aroma will fill your kitchen, promising a comforting meal ahead.
Step 8: Add Finishing Touches
Remove the ratatouille from the oven and let it cool slightly. As a final flourish, sprinkle freshly grated Parmesan cheese over the top, allowing it to melt slightly into the warm dish. This creamy topping takes your Oven-Roasted Ratatouille to an indulgent level that’s simply irresistible.

The more vibrant your vegetables, the more visually appealing and delicious your ratatouille will be!
