Scallop Potatos
1/4 cup butter
1 1/2 cups onion, diced
2 tbsp all-purpose flour
2 cups whole milk
2 cloves garlic
2 1/4 cups shredded cheese (I used a blend of cheddar, mozzarella, and monterey jack), divided
1/3 cup chives, snipped
4 large yukon gold potatoes (any kind will do), skins on, thinly sliced
The sauce was then poured over the potatoes and the whole thing was given a good shimmy shake on the counter top to get the sauce to ooze down into all the nooks and crannies. The top was sprinkled with the remaining 1/4 cup of cheese and another sprinkling of chives. I then placed the casserole dish on a baking sheet in case it bubbled over (it didn't) and baked it for 60 minutes until brown and bubbly.
