Cheesy Au Gratin Potatoes

Cheesy Au Gratin Potatoes
Up today, front and center is a wonderfully tasty recipe for Cheesy Au Gratin Potatoes. I found this little treasure at Mels Kitchen Cafe.
She’s a good one, that girl. Her site is chuck full of fabulous recipes.
This particular version of Cheesy Au Gratin Potatoes can be put together fairly quickly as it doesn’t require making a cheesy sauce. Rather the cheese is tossed with a little bit of cornstarch and then layered with potatoes. A mixture of broth and half and half is then poured over everything and vwalla….delicious, 
Cheesy Au Gratin Potatoes. 
This yummy dish gets consumed VERY quickly around here 
and is perfect served with Grandpa Marks Meatloaf
Hope you love it…
Hope you have a great day…
and thanks so much for stopping by!
Cheesy Au Gratin Potatoes
Time: 20 minutes prep + 80 minutes to bake
Yield: 6 servings
Recipe adapted from Mels Kitchen Cafe
2 1/2 C sharp cheddar cheese, grated
1/2 C Parmesan cheese, grated
2 t cornstarch
5 large russet potatoes, peeled and sliced thinly
salt and pepper
3/4 C half and half
1/2 C chicken broth
1. Peel your potatoes and slice them as thin as you can. You need them to be about 1/8 of an inch thick. 
2. Spray a 3 quart baking dish with cooking spray. Layer half of the potatoes evenly over the bottom. 
3. Sprinkle with salt and pepper. 
4. In a medium sized mixing bowl combine the cheeses and the cornstarch. Just toss them around with your fingers to get them all combined. Sprinkle half of the cheese mixture over the potatoes. 
4. Layer the rest of the potatoes over the cheese and sprinkle with salt and pepper. In a large measuring cup combine the half and half and the chicken broth. Pour it over the potatoes. 
5. Sprinkle the rest of the cheese over the top. Cover and bake at 350 degrees for 45 minutes. Remove your cover and bake for the remaining 20 minutes, or until the potatoes are cooked through.

    Congrats to the winners.

    I love au gratin taters, so decadent and good. Put some fresh herbs on top and I am in LOVE.

    Shut the front door! Are you serious! Not only do I NEVER win ANYTHING, but I have been on the hunt for a good Au Gratin potato recipe…seriously, I even googled it and came up with nothing. You are the best Jamie! I told my husband I saw you the other day and he wondered if I got your autograph…or at least a picture with you. I explained that neither one of us was “camera ready” and that I actually HAVE had my picture taken with you. 🙂 So, if you don't mind signing that cookbook that would be lovely. Ha ha. 🙂

    I have sort of a strange question. I frequently want to make things for dinner that all have to be baked (i.e. meatloaf and cheesy au gratin potatoes) but I only have one oven. Some things with short baking times I can stagger…but not always. So my question is, is it ever possible to bake 2 things at once? Especially if the two dishes are small (there are only 2 adults & 1 baby in this family) and don't take up the whole oven? Could I bake a small version of the meatloaf and potatoes and bake them together? Thanks for your help. I love ALL your recipes!

    Love your step-by-step photos! And I'm happy you like this dish – it is so classic. It is made and devoured often around these parts, too!

    I found your blog recently and am loving it! I noticed that the recipe above didn't have a temperature listed to cook the potatoes. I'm guessing it's 350 degrees? I jumped over to Mel's Kitchen Cafe and that's the temp. she cooked them at. Thanks for the great recipes!

    Your question is not strange at all! And you will be pleased that the answer is most definitely yes. I cooked both the Meatloaf and the Au Gratin Potatoes at the same time in my oven, side by side. You need to be a little more cautious if you put one on top rack and one on the lower. They would need to switch places half way through the cooking time. Hope you try both the recipes and they turn out well for you and your family.

    Thanks for the tip about the cooking temperature. It is 350 degrees as you saw on Melanie's site. I always appreciate a heads up when there is something missing in a post. Thanks for taking the time to tell me.

    Have a good night!

      Hi Melissa Bo,
      Thanks for your question. I haven't ever had good luck with recipes like this (a lot of cheese and milk) in the crock pot. The cheese kind of gets curdled and gross. Bummer, isn't it. I would say stick with the oven on this one.
      Good luck!

    made these many times, they are sooo yummy. Except that i think Mel uses heavy cream, instead of half and half. maybe i will try it with half and half.

    I made the Cheesy Au Gratin Potatoes for Easter, but my potatoes turned out runny ~ Not sure what happened, but wondering what I could do to avoid this next time? Thanks!

    These are delicious! My mom, who is a good cook says she’s always struggled making au gratin potatoes- until I introduced her to this recipe! I add minced garlic to it on each layer, since garlic makes everything even better 🙂 Thanks for another delicious recipe!

    HELP — What temperature do I cook the au gratin potatoes at? I do not see a temperature listed. Thanks much & I enjoy your blog lots. Have made many of your recipes and have never been disappointed.

    So her original recipe calls for heavy whipping cream instead of half & half. Anyone have any thoughts on this? I am making this for the first time with guests coming over, so I am a bit nervous.

    I’ve never made au gratin potatoes before and I just wanted to clarify 2t of cornstarch is 2 teaspoon? Or table spoon? Thanks.
