Ingredients
- 3pounds russet potatoes, peeled
- 2tablespoons unsalted butter
- 4ounces shallots, diced
- 1medium carrot, diced
- 1small zucchini, diced
- 1cup frozen peas, thawed
- 2cloves garlic, minced
- 2tablespoons stemmed thyme
- 1teaspoon salt
- ½teaspoon freshly ground black pepper
- ¼teaspoon grated or ground mace
- 3cups reduced-sodium vegetable broth
- 1cup low-fat or fat-free cream
Preparation
- Step 1
Position the rack in the center of the oven and preheat the oven to 350 degrees Fahrenheit. Peel and thinly slice the potatoes. Place the slices in a bowl, cover with cool water and set aside.
- Step 2
Melt the butter in a large skillet over medium heat.
- Step 3
Add the shallots, carrot, zucchini and peas. Cook, stirring often, until softened, about 3 minutes.
- Step 4
Add the garlic, thyme, salt, pepper and mace. Stir well to warm through. Remove from the heat.
- Step 5
Layer the potatoes and vegetable mixture in a 10-cup gratin or 9-by-13-inch baking dish by first blotting some potato slices on a paper towel, then layering them across the bottom of the dish. Add some of the vegetable mixture, spread it over the slices, then blot dry more slices and add them as another layer. Keep layering the casserole, like a lasagna, ending with a layer of potato slices.
- Step 6
Whisk the broth and cream in a large bowl. Pour it over the contents of the baking dish.
- Step 7
Bake, uncovered, basting occasionally, until it is golden and most of the liquid has been absorbed, about 2 hours.

Delicious, well balanced, healthy -- would recommend doubling the non-potato veggies (everything from the butter down through the black pepper), as I found it to be a bit dominated by potatoes.
Great flavor! Would reduce cooking time by ~30 minutes. Also reduce the amount of vegetable broth and/or add a roux or other binding agent as the "sauce" did not thicken nearly as much as we would have liked.
Made this today, it’s delicious. We used oat milk actually, and it turned out great - but we also doubled the non-potato veggies as suggested by others. Did not have any complaints about the ratios and wetness. I am curious about the effect of adding an egg, I mean, it’s not cheesy lol so maybe the egg would have a nice impact? I might try next time.
