Ingredients
- Olive oil spray
- 3 pounds yellow potatoes, like Yukon gold, unpeeled, sliced into 1/4-inch slices
- 3 cups cold milk (1 percent low-fat)
- 1/4 cup all-purpose flour
- 2 cloves garlic, minced
- 1 large or 2 small sprigs thyme
- 1 3/4 cups grated Gruyere cheese (6 ounces)
- 1 1/2 teaspoons salt
Directions
Preheat the oven to 350 degrees F. Spray a 2 quart, shallow baking dish with olive oil spray.
Put the potatoes into a large pot and cover with water. Bring to a boil over medium heat. Reduce the heat and simmer until the potatoes are just tender, about 8 minutes. Drain and set aside to cool somewhat.
Put the milk and flour into a large saucepan and whisk until the flour is dissolved. Add the garlic and thyme and heat over a medium-high heat, stirring constantly, until the mixture comes to a boil and is thickened, about 8 minutes. Remove from the heat, discard the thyme sprig, and stir in the salt. Add 1 cup of the cheese and stir until melted.
Arrange half of the potatoes in the baking dish. Pour over half of the cheese sauce. Add the remaining potatoes and top with rest of the sauce. Sprinkle with the remaining cheese and bake for 25 minutes, until bubbling. Put under the broiler and broil on high until the top is browned, about 2 minutes. Serve hot.

Anytime I make a white sauce, I always add nutmeg. You also need to salt the water for the potatoes because potatoes love salt and they'll just soak up what little bit is in the sauce and leave everything tasting bland. It is also important to use a good cheese. Try not to buy something already shredded and processed...shred it yourself and burn a few calories at the same time. (: Another thing to do is to chop the thyme and leave it in the dish so it adds more flavor. I used all of those tricks and it came out amazing. I have also just cut the potatoes much thinner and cooked it in the oven for less clean-up. It's a winner!

I don't know why other people are saying this was bland. We all loved it. I halved the recipe since there were only 3 of us so I made 4 medium sized yukons. The sauce thickened up nice and was super cheesy. I cracked fresh pepper over each layer of the potatoes. The quick broil at the end gave a nice crisp to the top layer. This will be my good-to recipe for a healthy au gratin.

Not at all tasty. I watched the video and it looked delicious. Mine also looked delicious but when we dug in at dinner the dish was tasteless. Ellie should have warned us that this lower calorie dish had no flavor
