Would you just look at all of those yummy veggies and cheese!
From: Home Cooking Montana
1 lg. yellow onion, cut in half and sliced
2 cloves garlic, minced
unpeeled potatoes, slice in 1/4" thick rounds (I used red potatoes)
1 zucchini, slice in 1/4" thick rounds
1 yellow squash, slice in 1/4" thick rounds
2-3 roma tomatoes, slice in 1/4" thick rounds
kosher salt/pepper to taste
fresh thyme leaves, plus extra springs
gruyere cheese, grated (can use parmesan)
Preheat oven to 375 degrees.Brush a baking dish with olive oil. In a medium saute pan, heat about 1-2 Tbs. of olive oil and cook the onions over medium-low heat or until translucent. It should take about 8-10 minutes. Add the garlic and cook an additional minute. Spread the onion mixture on the bottom of the oiled baking dish.
Layer them alternately on top of the onions. Fit them tightly, making only 1 layer. Sprinkle with some kosher salt and pepper. Add some of the thyme leaves and a few thyme springs. Drizzle with a bit of olive oil, about 1 Tbs. or so. Cover the dish with foil. Bake for about 35-40 minutes or until the potatoes are tender. Uncover the dish, remove the thyme sprigs. Sprinkle with some grated cheese. Bake the Vegetable Tian for another 30 minutes or until browned. Serve warm.
