You say potato, I say sign me up!
I love all things potato, and the ability to incorporate them into my Whole30 meals is essential — especially when I’m feeling a bit grumpier than usual in the first week. Good riddance, sugar cravings. Hello, Whole30 Scalloped Potatoes.
This recipe is one I’ve been tweaking through the years, just to see if little differences would make it better. You really can’t go wrong with this onion-gravy mixture layered with humble russet potato slices.
This is a low-cost side dish that packs a heck of a lot of flavor and can pair with your protein and veggies of choice. Just know this will be the star dish on your plate.
Ingredients
- 3 pounds russet potatoes (about 3 medium potatoes)
- 3 tablespoons ghee
- 1 small onion, thinly sliced
- 3 teaspoons minced garlic
- 2 heaping tablespoons arrowroot flour
- 1 teaspoon dried mustard
- 2½ cups almond milk
- 1½ teaspoons kosher salt
- ½ teaspoon cracked black pepper
- 1 tablespoon dried thyme
Instructions
Preheat oven to 400 degrees F.
Wash potatoes and thinly slice into ⅛-inch thick slices. Set aside.
Add ghee to a large skillet heated over medium-high. Once ghee is heated, add sliced onion and cook until soft, about 4 to 5 minutes.
Add minced garlic and ½ teaspoon kosher salt to the skillet and cook for another minute. Reduce heat to medium.
Stir in arrowroot flour and dried mustard. Continue stirring for about 30 to 45 seconds before slowly pouring in the almond milk, stopping to stir about halfway through. Add 1 teaspoon salt, ½ teaspoon pepper and 1 tablespoon thyme.
Continue stirring until sauce starts to thicken and just simmer. Remove from heat.
Arrange a layer of potato slices to cover the bottom of a 2½ or 3 quart baking dish. Add a few spoonfuls of the sauce and repeat layers two more times, finishing with the remaining sauce on the top layer. Use the back of a spoon to smooth sauce completely over the top layer.
Cover the baking dish with foil and bake in preheated oven for 30 minutes. Remove foil and bake for another 25 to 30 minutes, until potatoes are cooked through and top is golden brown.
Let rest for a few minutes and serve.
