I have a serious addiction to potatoes. I love them in any form and we have potatoes fairly often. DH is not a fan but humors me. I found this recipe on allrecipes and changed it around a bit to suit me and it’s delish!
This recipe is pretty easy even though you will have to make a cheese sauce. Just take your time and it will work. I especially love that it makes a small casserole so if you are a small family, it will work perfectly.
Cheesy Au Gratin Potato Casserole
4 russet potatoes, sliced into very thin slices
1 onion, sliced into thin rings
salt and pepper to taste
3 tbsps butter
3 tbsps flour
1/2 tsp salt
2 cups milk (I used 2%)
1 1/2 cups shredded Cheddar cheese
Preheat oven to 400º and grease a 1 quart casserole dish. I used a 9×9 glass dish.
Layer half the potato slices in the bottom of the dish, top with all the onion slices, top onions with the rest of the potatoes and season with salt and pepper if desired.
In a medium saucepan, melt the butter over medium heat. Mix in flour and salt and whisk continuously for 1 minute. Stir in milk and continue whisking until the mixture thickens. Stir in the cheese ALL AT ONCE and stir until the cheese melts, about 60 seconds or so. Pour sauce over the potatoes. Cover dish with aluminum foil.
Bake for 1 1/2 hours.
Makes 4-6 servings.
