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.

Ingredients

  • 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

Instructions

  • 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!

Notes

  • 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.
