How to Make Ratatouille
Step 1: Preheat the Oven
Set your oven to 375 degrees F (190 degrees C) to get it warm and ready for baking the ratatouille.
Step 2: Blend the Sauce
In a blender, combine the drained diced tomatoes, olive oil, balsamic vinegar, herbs de Provence, and garlic. Puree the mixture until smooth and adjust with salt and pepper to taste.
Step 3: Prepare the Casserole Dish
Spread the smooth sauce in a thin, even layer across a medium-sized round or oval casserole dish, ensuring it's well coated.
Step 4: Arrange the Vegetables
Layer the sliced tomatoes, zucchini, eggplant, and onion in a spiral pattern, alternating them as you go. Make sure the eggplant pieces are cut into quarters for even cooking.
Step 5: Dress and Season
Drizzle olive oil over the arranged vegetables, then sprinkle with sea salt and black pepper to season.
Step 6: Bake to Perfection
Place the casserole dish in the oven and bake for 30 to 35 minutes. Look for the veggies to become tender and the sauce to bubble at the edges.

Pro Tips from My Kitchen
✓ Perfect Spiral – For a visually stunning presentation, try to maintain an even thickness when slicing your vegetables. This helps them cook uniformly and look fabulous.
✓ Eggplant Magic – To remove any bitterness from the eggplant, sprinkle a little salt on the slices and let them sit for 10 minutes, then rinse well before use.
✓ Sauce Control – Want more sauce? Double the ingredients for the sauce if you prefer a juicier ratatouille.
✓ Make it Ahead – This dish tastes even better the next day as the flavors meld together. Feel free to prepare it a day in advance.
✓ Fresh is Best – Use fresh herbs when possible. They add life to the dish that dried ones cannot match.
What Makes This Recipe Work
- The combination of tomatoes, zucchini, and eggplant creates a harmonious balance of textures, with each vegetable bringing its own unique profile. This interaction makes every bite exciting and layered with flavor.
- The use of a blended sauce as a base allows the vegetables to cook evenly and infuse with sweet, tangy, and herbaceous notes. The oven's heat concentrates the flavors beautifully.
- The spiral pattern of vegetable arrangement ensures that the heat is evenly distributed, allowing each piece to bake perfectly without any part becoming mushy or overcooked.
Frequently Asked Questions About Ratatouille
