Ingredients
-
4 Russet Potatoes
-
1 White Onion
-
3 Tbsp. Gluten-Free All Purpose Flour
-
3 Tbsp. Butter
-
2 C. Whole Milk
-
2 tsp. Salt
-
1 tsp. Black Pepper
-
¼ tsp. Nutmeg
-
¼ tsp. Rubbed Sage
-
1 C. Gruyere Cheese, grated
-
1 C. Sharp Cheddar, grated
-
3 Slices Canyon Bakehouse Bread, stale or toasted and grated
Directions

- Preheat oven to 400 degrees and prepare a 9×12 baking dish with butter or cooking spray.
- Peel and thinly slice the potatoes and onion. Alternating, layer them into the baking dish.
- Melt the butter in a 3 qt. stock pot. Whisking, add the flour and cook for 1-2 minutes.
- Continue whisking the butter and flour mixture and slowly add the milk. Add the seasonings and bring the sauce to a simmer.
- Once the sauce begins to thicken, fold in the grated cheeses, reserving ½ C. for the top.
- Lifting the layers, pour the sauce onto the potatoes and onions, allowing it to soak in.
- Top the casserole with the remaining shredded cheese and the breadcrumbs.
- Cover the casserole with foil and bake for 1 hour. Remove the foil for the last 15-20 minutes to brown the top.
