Creamy and Crispy Scalloped Potatoes

Step 1
Preheat oven to 400 degrees F (200 degrees C). Grease a 1-quart casserole dish.

Step 2
Spread about 1/3 of the potatoes into the bottom of the prepared dish. Mix flour and salt together in a bowl; sprinkle about 1/3 of the mixture over the potatoes. Dot potato layer with about 1/3 of the butter. Sprinkle about 1/3 of the onion over the potatoes. Repeat layering twice more.

Step 3
Stream milk over the potato mixture in the casserole. Sprinkle paprika over everything.

Step 4
Bake in preheated oven until the top is nicely browned, about 1 hour.
