Tender Yukon Gold potatoes are layered with cheddar cheese and diced onions to make a cheesy, cozy, and comfy Scalloped Potatoes casserole, just like grandma used to make.

An Easy Cheesy Scalloped Potato Recipe

What do you think of when you think “scalloped potatoes”? I think of special occasions, like Christmas and Easter! But, the deliciousness that is scalloped potatoes really should be on the table more often, don’t you think?

If you’re not familiar, scalloped potatoes are thinly sliced whole potatoes layered with cheese and onions, and cooked in a casserole dish until tender. Most recipes call for milk as well, so the whole dish is creamy and saucy. I know, totally drooling over here, too. 🤤

Recipe Ingredients

Nothing artificial here! This scalloped potatoes recipe is the real deal: real milk, real potatoes, and real cheese. Total Yum. For the meat-lover, hop over to this similar but beefy hamburger potato casserole.

• Potatoes: I recommend using Yukon Gold potatoes, but Russet potatoes are also a good option.
• Onion: You’ll need 1 small onion. I typically use yellow onion, but you can also use white or sweet onions.
• Butter: Have ready 3 tablespoons of butter, cubed, plus more to grease the baking dish.
• All Purpose Flour: To thicken the sauce, you’ll need 3 tablespoons of all-purpose flour.
• Milk: You can use any kind of milk here. 
• Salt and Black Pepper: Simple seasoning that will enhance the flavors.
• Cheese: I usually go with regular cheddar, but feel free to substitute Gruyere, Colby, or any other cheese you enjoy.
• Fresh Parsley: For garnish.

How to Make Scalloped Potatoes from Scratch

It’s finally time to give those spuds some love and scallop them, not just for the holidays, but to celebrate the everyday, now and forever!

1. Prep the Baking Dish, Potatoes, and Onion. Lightly grease a medium 9-inch baking dish with butter. Peel the Yukon Gold potatoes, and thinly slice them with a sharp knife or mandolin. You want them to be roughly ¼-inch thick. Peel and finely dice the onion and set aside.
2. Layer the Potatoes, Onions, Flour, Seasonings, Butter, and Cheese. Arrange half of the sliced potatoes at the bottom of the prepared baking dish. Top with half of the flour, half the salt and pepper, half the shredded cheddar cheese, and half of the onion. Dot with half the butter. Repeat these layers one more time. 
3. Add the Milk. In a medium saucepan, heat the milk until warm to the touch. Pour the milk over the prepared potatoes. Cover the baking dish tightly with foil, and bake for approximately 45 minutes, or until the potatoes are hot and bubbly. Uncover and bake an additional 15 minutes, until the cheese is lightly browned.
4. Rest and Serve. Let the dish rest for roughly 5 minutes, to allow the sauce to thicken, and then serve it with your favorite main dish. 

Serving Suggestions

Scalloped potatoes make a wonderful meatless entree for a light meal, but they’re usually served alongside a main course. Cheesy scalloped potatoes are the perfect pairing with this recipe for Christmas ham with brown sugar glaze.

For the perfect sides, start with my air fryer Red Lobster biscuits or soft Parmesan dinner rolls. Then, dive into the main course with my delicious and easy juicy grilled pork chops. Also, my family loves it when I make this buttermilk fried chicken, and I think it goes perfectly with the oniony, cheesy goodness of a scalloped potato casserole. 

For a sweet finish, try my cherry kuchen bars or indulge in the creamy richness of my homemade lemon bars. 

How to Store and Reheat Leftovers

• To store leftovers, place in airtight containers and refrigerate. Scalloped potatoes will keep for 3 to 4 days, if stored properly.
• To reheat, bake at 350˚F until hot and bubbly all the way through. 

Can I Freeze Scalloped Potatoes?

Yes, you can. Cool the cooked scalloped potatoes, and pack into airtight freezer containers. Freeze for up to two weeks. Thaw overnight in the refrigerator before reheating.
