Instructions

1 Preheat your oven to 375°F (190°C) and lightly grease a 9-inch pie dish or similar oven-safe baking dish. Arrange the thinly sliced zucchini, yellow squash, tomatoes, and red onion in an alternating pattern, overlapping them slightly, to create a visually appealing spiral or concentric circles across the bottom of the dish. This arrangement will allow the vegetables to cook evenly and become tender.
2 In a small bowl, whisk together the extra virgin olive oil, fresh lemon juice, gluten-free Dijon mustard, minced garlic, dried Herbes de Provence, salt, and black pepper until well combined. This creates a flavorful dressing that will infuse the vegetables as they bake.
3 Drizzle the prepared dressing evenly over the arranged vegetables in the baking dish, ensuring each slice is lightly coated. The olive oil will help the vegetables soften and caramelize, while the herbs and lemon will add a bright, aromatic finish.
4 Cover the baking dish tightly with aluminum foil and bake for 20 minutes, or until the vegetables are beginning to soften. Remove the foil and continue baking for another 10-15 minutes, or until the vegetables are tender and the edges are slightly golden and caramelized. The total cooking time should be around 30-35 minutes.
5 Allow the Tian Provencal to rest for a few minutes before serving. This allows the flavors to meld and the dish to set slightly. Serve warm as a delightful side dish alongside your favorite main courses.

Tips & Notes

Slice the vegetables about the same width so the rows look neat and cook evenly.
Use a mandoline for even 1/8-inch slices, and use the guard.
Let the tian rest for a few minutes after baking, as step 5 says, so the juices settle.
