Oven-Baked Ratatouille with Fresh Basil
This Oven-Baked Ratatouille is a playful -- and easier! -- take on the classic Provençal dish highlighting fresh summer vegetables. Instead of cooking each ingredient individually, I take the quicker route of baking them together in one large dish. Enjoy as a light main course, a veggie-packed side dish for grilled meats, poultry, or seafood, or toss with pasta. I hope you give it a try, it's too good not to share! Gluten-free, dairy-free, and vegan.

- ⅓ cup extra virgin olive oil
- 2 long purple Italian eggplant or 1 large globe eggplant, cut into 1-inch pieces
- 1 large zucchini, cut into 1-inch pieces
- 1 large yellow squash, cut into 1-inch pieces
- 4 Roma tomatoes, cut into 1-inch pieces
- 1 pint cherry tomatoes, left whole
- 1 medium red onion, cut into 1-inch pieces
- 1 red bell pepper, stem and seeds removed, cut into 1-inch pieces
- 1 orange bell pepper, stem and seeds removed, cut into 1-inch pieces
- 4 cloves of garlic, finely chopped
- ¼ cup fresh basil leaves, julienned, plus additional basil leaves for serving
- 2 Tbsp chopped rosemary
- 2 tsp Kosher salt
- ½ tsp freshly ground black pepper
- Flaky sea salt, for serving
- 2-3 Tbsp aged balsamic vinegar
If you haven’t already, chop the veggies. Preheat an oven to 400F. All the vegetables should be roughly the same size. Chop and set aside.
Season the veggies. Place ⅓ cup extra virgin olive oil in a large baking dish, then place in the oven to heat for 5 minutes. Once hot, remove and carefully add all chopped vegetables and garlic to the dish. Sprinkle with ¼ cup thinly sliced basil, 2 Tbsp chopped rosemary, 2 tsp Kosher salt, ½ tsp freshly ground black pepper. Toss to evenly coat.
Roast the vegetables. Return to the oven, then cook for 50-60 minutes, tossing once halfway through, until the vegetables are tender and caramelized. This will take longer if the vegetables are cut into bigger pieces and/or if the pan is overflowing with vegetables. Keep an eye on them so they don’t burn, but they can cook for up to 2 hours, as needed.
Toss with balsamic, then serve. Drizzle with 2-3 Tbsp balsamic vinegar (to taste), then stir well. Serve immediately with a pinch of flaky sea salt and additional fresh basil. Enjoy!
- Can be enjoyed on its own as a light vegetable side dish, tossed with pasta, for breakfast with fried or poached eggs, spread onto sandwiches or crostini, or spooned over roast chicken.
- To prep ahead: You can prepare the vegetables and season them in advance. Store them covered in the refrigerator for up to 24 hours before baking.
- Leftovers and storage: Store leftovers in an airtight container in the refrigerator for up to 4 days.
- Reheating: Reheat in the oven at 350°F (175°C) until warmed through, or in the microwave.
- To freeze: Ratatouille can be frozen. Allow it to cool completely, then transfer to a freezer-safe container. It can be stored for up to 3 months. Thaw overnight in the refrigerator before reheating. Note that the veggies will soften as they thaw and will have a softer texture than if enjoyed immediately.
