Instructions
1
Position a rack in the center of the oven and preheat to 400°F. In a medium pot over medium heat, add the oil. When it’s hot and shimmering, add the herbes de Provence, garlic, onions, and bay leaf, cover the pot, and cook, stirring occasionally, until soft and fragrant, about 10 minutes.
2
Turn the heat to high, stir in the zucchini, bell peppers, eggplant, and tomatoes, and season to taste with salt and black pepper. Uncover the pot and bake, stirring occasionally, until the vegetables are tender and lightly browned, about 1½ hours.
3
Remove the pot from the oven, then stir in the basil and parsley. Transfer the ratatouille to a wide bowl and serve warm or at room temperature.

Tips & Notes
Pro tips
Sauté the herbes de Provence in hot oil for 30 seconds before adding garlic and onions to fully release their fragrance.
Cut all vegetables into uniform 2-inch pieces so they cook evenly in the 1½-hour bake.
Drain the canned tomatoes before adding to prevent excess liquid; stir occasionally during baking for even browning.
Stir in fresh basil and parsley only after removing from the oven to preserve their bright flavor.
Substitutions
Yellow onions → white or red onions (slightly different sweetness; red adds mild color)
Herbes de Provence → equal amount dried oregano + thyme blend (loses some complexity)
Canned tomatoes → 10 fresh medium tomatoes, quartered (may need slightly longer cooking; omit draining)
Storage & make-ahead
Cool completely and refrigerate in an airtight container for up to 4 days. Reheat gently over low heat or serve cold; do not freeze as texture degrades.
Common Questions
Can I make ratatouille ahead of time?
Yes. Ratatouille tastes better the next day as flavors meld. Cool completely, refrigerate in an airtight container for up to 4 days, then reheat gently over low heat or serve cold.
Should I peel the eggplant?
No. The skin holds the eggplant together during the 1½-hour bake and becomes tender. Leave it unpeeled.
Can I use fresh herbs instead of dried herbes de Provence?
Fresh herbs won't have the same concentrated flavor and will wilt during cooking. Stick with dried herbes de Provence (1 Tbsp.), or use 1 tsp. dried thyme plus ½ tsp. dried marjoram if needed.
What does the ratatouille look like when done?
The vegetables should be fork-tender and lightly browned at the edges. The oil may pool slightly on top; this is normal.
Can I halve this recipe?
Yes. Divide all ingredients by 2 and reduce baking time to about 1 hour, checking for tenderness at 45 minutes.
