Scalloped Tators and Ham GFCF

One of my favorite crock pot comfort foods is scalloped potatoes and ham. Adapting this family favorite to gluten and casein free was a piece of cake. (Now you're in the mood for cake, aren't you? Sorry. I'll do a cake recipe soon.)
Each layer in the crockpot had about this much ham and tators. I did two layers.

Smother each layer in this creamy sauce...

Cut up one onion and sautee until soft in 4-5 Tablespoons of olive oil or ghee (clarified butter). Add 1/2 cup of your favorite GF flour blend and blend to make a roux. Slowly add 3 cups of chicken stock and 1 cup of almond or flax milk. Cook until thickened.

Sprinkle with pepper and set crock pot on high for 6 hours. That's it! Easy peasy...

...and good! Java had two large helpings last night and heated some up this morning for breakfast!
