Test Kitchen Tips

Before you peel potatoes, scrub them with a vegetable brush under cold water. Remove eyes or sprouts.

When working with a lot of potatoes, place them in cold water after peeling to prevent discoloring.

These are our all-time favorite cheesy potato casseroles.

Delicious!! I used 9 medium/large potatoes, doubled the sauce/cheese ingredients and used a 9x13 baking dish. I omitted the onion, not by choice, but because I simply forgot to put them in! Still, these potatoes were wonderful. I baked them about an hour and fifteen minutes, covered, and then continued to bake another thirty minutes, uncovered. They came out perfect. The potatoes were tender and covered in the cheesy sauce. Perfect accompaniment to the glazed ham we had with it. Will keep this recipe handy anytime I need a potato side dish!

Made this multiple times. This is a simple good recipe. I use extra sharp cheese and grate extra to sprinkle on top during the last 30 minutes of cooking.

After having read most of the reviews, I put the sliced potatoes in cold water and boiled them for 10 minutes only. I then added about half a cup of gruyere cheese and half a teaspoon of smoked paprika, to the sauce and poured it over the warm potatoes and baked it according to the recipe,it was amazing

Excellent and easy recipe. I ended up with about 6 cups sliced potatoes, cut the salt to 1 tsp, and used 1 1/2 cups cheese. Sauce-to-potato ratio was perfect, but I did have to bake mine an extra half hour. Thanks for the great recipe...will be adding this to my rotation!

As mentioned before, potatoes were still quite firm at the end of the cooking process. I think an adjustment in the baking temperature to 375 or even 400 would fix this. I hand cut my potatoes and I felt I cut them fairly thin but maybe a thinner cut is also needed.

Super easy to do. I added garlic powder for some flavor and more pepper than was called for. I baked at 350° for 40 minutes (more like 42 as I didn't hear the timer right away!) and they were perfect. The family LOVED them! I'll be adding this as a regular recipe to pull out for a side!

Was easy, but I thought it needed more flavor.

Was tasty when it finally finished cooking but the time listed in the recipe was way off! The potatoes were still hard after an hour and it took another half hour at 450 before they were soft enough to eat.
