Creamy Au Gratin Potatoes

Rated as 4.53 out of 5 Stars

"This is my husband's favorite dish, and he considers it a special occasion every time I make it. The creamy cheese sauce and the tender potatoes in this classic French dish combine to make a deliciously addictive experience. It's a great side dish with a roast pork loin or beef tenderloin. Add a green salad and French bread, and you have found the magic path to a man's heart. To avoid lumps in your sauce, add the milk just a little at a time as you stir the flour and butter. Experiment with different cheeses for variety."

  1. Preheat oven to 400 degrees F (200 degrees C). Butter a 1 quart casserole dish.
  2. Layer 1/2 of the potatoes into bottom of the prepared casserole dish. Top with the onion slices, and add the remaining potatoes. Season with salt and pepper to taste.
  3. In a medium-size saucepan, melt butter over medium heat. Mix in the flour and salt, and stir constantly with a whisk for one minute. Stir in milk. Cook until mixture has thickened. Stir in cheese all at once, and continue stirring until melted, about 30 to 60 seconds. Pour cheese over the potatoes, and cover the dish with aluminum foil.
  4. Bake 1 1/2 hours in the preheated oven.

I'm constantly asked to make my version of this recipe. Here's what I do differently that I think makes it better. 1. No onions. (I think they just get in the way of the potato and cheese fla...

Good overall, but on the bland side. Found the onions sliced into rings changed the overall texture and appearance of this dish. Also, potatoes sliced at 1/4 inch were not done at 1.5 hours. P...

Made exactly as directed, only change being mincing the onion instead of rings, as I don't like the texture of onions in large chunks. One reason I chose this recipe was because I prefer whole, ...

I thought this recipe was very, very good. I will not make Au Gratin Potatoes from a box mix again! I'm rating it 4 stars instead of 5 because I feel a few simple changes are needed. I would ...

This was easy and delicious! I sliced then microwaved the potatoes for about 8 minutes to cut down on baking time. Then poured the cheese sauce over top and mixed with potato slices, then bake.

Good recipe, nice as a side w/baked ham. Modified slightly by sauteeing onions 1st w/a bit of fresh/minced garlic for 4 min to reduce "raw" onion taste B4 adding to layers. Also agree to remove...

Creamy, saucy and delicately flavored potatoes which are the perfect accompaniment to more robustly seasoned meats. Would be better, however, with onions chopped rather than sliced, and to uncov...

My husband and I loved this so much... My makin them out of the box days are over... I made just a couple changes... I sprinkled garlic powder on both layers of the potatoes...I also used marble...
