The classic side dish recipe gets an upgrade in these gluten free scalloped potatoes. You're going to love these tender, creamy potatoes made with simple ingredients.
Preheat the oven to 375 °F (191 °C). Spray a 9x13 baking pan with nonstick cooking spray and set aside.
Wash and peel the potatoes. Then slice them very thin (⅛ inch or less) using a mandoline slicer. Do NOT rinse the potatoes after slicing.
Add the butter to a saucepan over medium heat.
¼ Cup (56 g) Vegan Butter
Once the butter is melted, add the garlic and fresh thyme. Cook while stirring for 1 minute until fragrant.
3 cloves Garlic, 1 teaspoon Fresh Thyme
Add in the flour, 1 teaspoon salt and pepper. Continue to cook for about 2 minutes, while stirring. A thick paste should form.
¼ Cup (37 g) Gluten Free 1-to-1 Flour Blend, 1 ½ teaspoon Kosher Salt, ½ teaspoon Black Pepper
Slowly add in the milk, while whisking. Then stir in the chicken broth. Continue to cook, while whisking slowly, until the sauce is thickened. This takes about 10 minutes.
2 Cups (452 g) Non Dairy Milk, 1 Cup (235 g) Gluten Free Chicken Broth
Add ⅓ of the potato slices to the bottom of the casserole dish. Sprinkle with a little of the remaining salt.
3 pounds (1362 g) Yukon Gold Potatoes
Cover with ½ of the onion. Then pour in ⅓ of the cream sauce. Repeat with a second layer of potatoes-onion-sauce, then finish with potatoes and sauce on top.
½ medium (150 g) Yellow Onion
Cover the baking dish with aluminum foil. Bake in the preheated oven for 30 minutes. Then remove the foil and bake uncovered for another 30-40 minutes or until the potatoes are fork tender.
Allow the potatoes to rest for about 15 minutes before serving.
Sprinkle the top with fresh parsley and serve.
Parsley for garnish
