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! 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!
Cheesy Mashed Potato Casserole
Ingredients
Instructions
-
Set a pot of water over high heat to boil. Scrub the outside of the potatoes with water and a bristled brush (no need to peel!). Dice into 1 to 2 inch pieces. Add the potato pieces to the water and cook until tender when pierced with a fork, about 15 to 20 minutes.
-
Drain the water and puree the potatoes with an electric mixer or hand masher. Mix in the butter, milk, salt, and pepper until thoroughly combined and smooth being careful not to overmix.
-
Turn the oven broiler to high. Transfer the potatoes to a baking dish and top with an even layer of the grated cheese. Place it right under the broiler until the cheese is melted and just begins to brown (be sure to watch it closely!), about 5 to 8 minutes. Serve warm.
Recipe Notes
Make Ahead: Complete steps 1 and 2 in advance and refrigerate the mashed potatoes overnight. Then prior to step 3, heat the potatoes in the oven at 350 degrees F for 20 to 30 minutes.

November 6, 2014 at 5:44 pmAn 8X8 or 9X9 would work!

November 6, 2014 at 4:34 pmSix to eight servings? Yes, if you’re serving squirrels!

November 6, 2014 at 5:45 pmJessy – I was thinking of a holiday table with a variety of sides to choose from.

November 6, 2014 at 6:54 pmHi 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!

November 7, 2014 at 10:19 amMy 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!

November 11, 2014 at 12:46 amHa! 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 :)

November 6, 2014 at 6:07 pmI 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!

November 7, 2014 at 10:15 amMmm 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!

November 10, 2014 at 12:52 pmI 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?

November 27, 2014 at 8:39 pmWe 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.

February 19, 2015 at 3:07 pmHello! 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.
