Best 7 Garden Vegetable Gratin Recipes

VEGETABLE TIAN

Steps:

• Preheat the oven to 375 degrees F.
• Brush a 9 by 13 by 2-inch baking dish with olive oil. In a medium saute pan, heat 2 tablespoons of olive oil and cook the onions over medium-low heat for 8 to 10 minutes, until translucent. Add the garlic and cook for another minute. Spread the onion mixture on the bottom of the baking dish.
• Slice the potatoes, zucchini, and tomatoes in 1/4-inch thick slices. Layer them alternately in the dish on top of the onions, fitting them tightly, making only 1 layer. Sprinkle with salt, pepper, thyme leaves, and thyme sprigs and drizzle with 1 more tablespoon of olive oil. Cover the dish with aluminum foil and bake for 35 to 40 minutes, until the potatoes are tender. Uncover the dish, remove the thyme sprigs, sprinkle the cheese on top, and bake for another 30 minutes until browned. Serve warm.

VEGETABLE GRATIN

Steps:

• In a large saute pan set over medium heat, add enough olive oil to lightly coat the bottom of the pan. When the oil is hot, add the onions and saute until translucent, but not browned, about 5 minutes. Add the garlic and cook for 1 minute, stirring. Add the tomatoes and cook until they start to give off their liquid, about 5 minutes. Add the thyme and season with salt and pepper. Add the sugar and cook until there is almost no liquid left, about 10 to 15 minutes, stirring frequently. Remove from the heat.
• Preheat the oven to 450 degrees F.
• Lay the eggplant and zucchini out on a flat surface and season with salt and pepper. Drizzle with olive oil.
• In another large saute pan set over medium high heat, add enough olive oil to coat the bottom of the pan. When the oil just starts to smoke, add the eggplant in 1 layer and cook just until golden brown on both sides, about 2 to 3 minutes per side. You might need to do this in batches. Remove to a paper towel lined plate. Blot the top with additional paper towels.
• In the same pan, add more olive oil to coat the bottom of the pan. When the oil just starts to smoke, add the zucchini in 1 layer and saute until just browned on each side, about 1 minute per side. Remove to a paper towel lined plate.
• In a shallow roasting pan or baking dish, spread half of the tomato sauce evenly over the bottom. Begin layering the eggplant and zucchini along the outside of the baking dish so they are overlapping slightly. Continue until the pan is full and the eggplant and zucchini is used. Cover the top with the remaining tomato sauce, spreading evenly. Sprinkle the mozzarella and Parmesan evenly over the top, covering completely.
• Place the baking dish inside a large baking dish. Pour hot water into the larger baking dish about half way up the sides to make a water bath. Bake for 25 minutes, or until the cheese is golden brown and bubbly. Remove from the oven and let sit for 5 minutes before serving.

PROVENCAL VEGETABLE GRATIN

Steps:

• Preheat the oven to 375 degrees F. Lightly grease a 7 by 11-inch baking dish with olive oil.
• Heat 2 tablespoons of the olive oil in a large skillet over medium low heat. Add onions, garlic and 1 teaspoon of the salt. Cook, stirring occasionally, for 5 minutes, until completely softened and cooked but not browned. Stir in the basil and thyme. Spread on the bottom of the prepared baking dish.
• Toss the sliced vegetables with the remaining olive oil and salt, and pepper. With the long side of the baking dish facing you, alternate the sliced vegetables in compact upright rows on top of the onion mixture.
• Cover the dish with aluminum foil and bake until the vegetables are softened, about 30 to 35 minutes. Uncover and sprinkle with the Parmesan. Continue baking until cheese begins to brown, about 20 minutes or so. Serve hot or at room temperature.

EGGPLANT GRATIN

Steps:

• Preheat the oven to 400 degrees F.
• Heat about 1/8-inch of olive oil in a very large frying pan over medium heat. When the oil is almost smoking, add several slices of eggplant and cook, turning once, until they are evenly browned on both sides and cooked through, about 5 minutes. Be careful, it splatters! Transfer the cooked eggplant slices to paper towels to drain. Add more oil, heat, and add more eggplant until all the slices are cooked.
• Meanwhile, in a small bowl, mix together the ricotta, egg, half-and-half, 1/4 cup of the Parmesan, 1/8 teaspoon salt, and 1/8 teaspoon pepper.
• In each of 2 individual gratin dishes, place a layer of eggplant slices, then sprinkle with Parmesan, salt and pepper and spoon 1/2 of the marinara sauce. Next, add a second layer of eggplant, more salt and pepper, half the ricotta mixture, and finally 1 tablespoon of grated Parmesan on top.
• Place the gratins on a baking sheet and bake for 25 to 30 minutes or until the custard sets and the top is browned. Serve warm.

ROOT VEGETABLE GRATIN

Steps:

• Preheat the oven to 350 degrees F. Butter a 13-by-10-by-2 1/2-inch baking dish.
• Heat 2 tablespoons of olive oil in a large (12-inch) saute pan over medium heat, add the onion and fennel and cook for 10 minutes, tossing occasionally, until lightly browned and tender. Add the garlic and cook for one minute.
• Meanwhile, in a large bowl, combine the onion mixture, sweet potatoes, celery root, Yukon Gold potatoes, cream, chicken stock, Gruyere, thyme, 1 tablespoon salt and 1 1/2 teaspoons pepper. Pour the mixture into the prepared baking dish and press lightly so the vegetables lie flat all the way to the edge. Combine the bread crumbs and 2 tablespoons of olive oil and distribute evenly on top. Bake uncovered for 1 1/2 hours, until the vegetables are very tender when tested with a small knife and the top is browned and bubbly. Allow to set for 15 minutes and serve hot.
• Make ahead: Bake in advance and reheat while the turkey rests, or assemble the dish, cover and refrigerate for up to 24 hours, then bake before serving.

GRATIN OF CARROTS & ROOT VEGETABLES

Steps:

• Preheat the oven to 180C/gas 4/fan 160C and butter a shallow ovenproof dish. Layer the potatoes, then the parsnip in the bottom of the dish with two of the sliced garlic cloves and sprinkle over a little salt and half the rosemary. It's best to keep the potatoes buried under the other vegetables because they go black if they are on top of the gratin.
• Pour the cream and milk into a large saucepan, add the rest of the rosemary and garlic, the carrots and a little seasoning. Bring to the boil, then turn the heat to the lowest it will go and simmer for 3 minutes.
• Pour the carrots and cream over the other vegetables, and spread the carrots out. Sprinkle over the parmesan, cover with foil and bake for 40 minutes. Remove the foil and bake a further 20 minutes until golden and bubbly.

CHEESY GREEN VEG GRATIN

Steps:

• Bring a pan of lightly salted water to the boil and cook the cauliflower florets for 3 mins. Add the broccoli and cook for 2 mins more. Drain in a colander and leave to steam-dry.
• Tip the spinach into a large saucepan, add 2 tbsp water and cook with the lid on over a low heat for 3-4 mins until wilted, then tip into a sieve and press the excess moisture out of it with the back of a wooden spoon. Set aside.
• Heat the oven to 220C/200C fan/gas 7. Melt the butter in a saucepan over a low heat until foaming, then stir in the flour to create a thick paste. Cook for 2 mins, remove the pan from the heat and whisk in the milk in several additions until lump-free. Return to the heat and whisk until thickened. Whisk in the mustard, most of the cheese and the chives. Season to taste.
• Arrange the vegetables, including the cauliflower leaves, in a medium ovenproof dish. Pour over the sauce, then sprinkle with the remaining cheese. Bake for 25-30 mins or until golden and bubbling.
