Homemade classic French ratatouille is the ultimate celebration of summer farmstand vegetables. Slow-baked in a garlicky tomato sauce and drizzled with fresh herb dressing, this French Provençal staple transforms simple garden ingredients into something irresistibly fragrant and hearty. This version is both plant-based and naturally gluten-free so everyone can enjoy a platter.
I first made this when my garden had an overload of zucchini and tomatoes and it became an instant family favorite. My kids love helping arrange the veggies.

Step-by-Step Instructions
- Slice the Vegetables:
- Set up a clean cutting board and slice eggplant zucchini tomatoes red onions and yellow bell pepper evenly into thin rounds Each piece should be about the width of a coin for even roasting and an attractive pattern
- Prepare the Herb Dressing:
- Finely chop fresh basil and parsley then combine with olive oil dried thyme and minced garlic in a small bowl Add a pinch of salt and pepper Stir until evenly mixed and set aside for flavors to meld
- Preheat the Oven:
- Set your oven to 200 degrees Celsius or 390 degrees Fahrenheit This ensures steady roasting and allows the vegetables to caramelize

- Heat olive oil in a large oven safe skillet over medium heat Add diced red onion and red bell pepper Sauté for about five to eight minutes until softened and lightly translucent Add minced garlic and cook for another minute until fragrant Season with salt pepper dried oregano and thyme Stir in crushed tomatoes until fully combined Lower heat and simmer for about ten minutes Allow it to thicken and stir in chopped fresh basil at the end
- Arrange the Ratatouille:
- Spoon the tomato sauce evenly across the base of your skillet or baking dish Starting from the outer edge arrange the sliced vegetables in an alternating pattern slightly overlapping in concentric circles Continue toward the center until the entire pan is filled Season the top with salt and pepper Drizzle the prepared herb dressing all over
- Bake:
- Cover the pan tightly with foil and transfer to the preheated oven Bake for forty minutes covered to gently soften the vegetables Uncover and bake for an additional twenty minutes so the tops caramelize and the edges char slightly

- Let the ratatouille rest for a few minutes out of the oven Serve hot on its own or with rice polenta or crusty bread

My favorite ingredient here is the fresh basil in both sauce and dressing Its aroma fills the kitchen with summer and always reminds me of long afternoons spent picking herbs with my children
