Total time: 1 h 30 min · Yields 6 servings
Preheat your oven to 190C (375F). Pour the prepared garlic confit oil and the softened garlic slices into the bottom of a 25cm baking dish, spreading evenly.
Arrange the sliced zucchini, squash, tomatoes, and onions in a tight shingle pattern around the dish. Work from the outside in until the dish is completely full.
Generously season the top of the vegetables with salt, pepper, and fresh thyme. Drizzle with an additional 2 tablespoons of olive oil to ensure the edges crisp up.
Cover the dish tightly with foil and bake for 30 minutes. This steams the vegetables through to ensure they are fork-tender.
Remove the foil. If using Parmesan, sprinkle it over the top now. Return to the oven for another 25 to 30 minutes until the edges are charred and the liquid has reduced.
Allow the tian to rest for 10 minutes before serving. This allows the juices to settle and the flavors to concentrate.
The garlic butter sauce is the star — pick sides that soak it up or balance the richness.
