Are you ready to kick up your classic mashed potato dish a few notches? If so, you are going to love this cheesy mashed potato casserole which has a layer of warm toasted cheese on top—yum! We also love these Creamy Mashed Potatoes!

Plus, I’ve added a make ahead note so this recipe can easily make an appearance on your holiday table this year. And since it calls for unpeeled potatoes, you can count on that extra nutritional punch that you wouldn’t get otherwise. Enjoy!

For a low carb idea, check out this Mashed Cauliflower!

Plain Mashed Potato Version

If you’re serving potatoes with a rich, flavorful dish like my Dijon Chicken Skillet with Kale Recipe (so yummy!), you can modify this recipe to make delicious “plain” mashed potatoes instead. Simply omit the cheese and the last step in the broiler. Easy!

For another casserole idea, make this Chicken Casserole!

  1. I live in the middle of nowhere and am curious what brands of cheese don’t use dye?? I haven’t been able to find cheese in my town that is dye free yet. Thank you!

    Hello! I love your website, have bought your cookbook, etc… Thank you for it all! This recipe was a huge hit at my house. Question – is this gluten-free? I’m making a meal for a gluten-free family and wanted to include this. Thanks in advance.

    We ended up making a double batch in a 13×9 dish to serve 10 people for Thanksgiving. A real hit, very easy, and something I felt good about serving.

  4. I don’t have Russet potatoes but do have butter golds and red potatoes, would either of these work without compromising the recipe? Which one would be better to use?

  5. Mmm looks awesome. I think I will take it 1 notch higher and add a little sour cream and green onion. I love your recipes, they’re simple and family friendly, easy to tweek for personal taste, but oh so good!

  6. cant wait to try this. on an unrelated note, i have a question about a recent post that i can not find, you mentioned that you ordered meat online and were pleased with it. i wanted to look into that option. can you send me the website info? thanks! love your posts!!!!

  7. I just love how you use simple and real ingredients. My kind of cooking! Often I see casserole recipes with all these extra and often unhealthy ingredients (e.g. canned soup). Obviously for those of us who would need more servings for a larger family or if using this as the main dish, you can simply double or triple the recipe like you would any other. :) I look forward to ordering your book!

        Hi Lisa. Personally, I like your idea of 6-8 serving sizes. Even with healthy eating, calories can soar and moderation is key! This looks both rich and yummy, so I will try it for sure this holiday!

      2. My favorite part of Thanksgiving is having tons of choices, and sampling a little everything! We are a military family, so our holiday table consists of people from all over the country, and everyone brings a dish. It’s an awesome time to try something different!

      3. Ha! I certainly didn’t expect a personal reply to my goofy comment! I actually really like the recipes I’ve gotten from your site but I definitely have to double them for my family of six. I apologize if I hurt your feelings, I must have been feeling particularly silly that day. I truly appreciate your effort to educate people about the importance of eating real food and hope your site continues to grow as more people get hip to the idea :)

  8. These look delicious! Can’t wait to try them. I loved the cheesy hashbrown casserole, so I know this will be good.
