As promised, here’s my recipe for scalloped potatoes from Christmas Dinner! Usually, I serve mashed potatoes at the holidays using this make-ahead recipe, but I wanted to change things up. This is simpler because it doesn’t require peeling or boiling, and it can be made the day before. In fact, next year that’s what I plan to do in order to save myself some stress on Christmas morning.
SCALLOPED POTATOES WITH ONION & CHEDDAR
also known as Potatoes Gratiné en Français 🙂
- 5 or 6 medium baking potatoes (about 2.5 lbs.)
- 1.5 C grated cheddar cheese
- 2 TBSP unsalted butter
- 1 onion, sliced thin
- 4 C whole milk
- 3/4 C light cream
- 2 to 3 garlic cloves, smashed
- 1 tsp Dijon mustard
- Salt & pepper
Preheat the oven to 375F and grease a large casserole/baking dish.
Slice the potatoes very thin. I am terrified of the mandoline and don’t own a large food processor, so I did this by hand, very carefully with a large, freshly-sharpened chef’s knife. Do not rinse. Set aside.
Prep the onions and garlic: slice the onion thin and smash the cloves of garlic with the side of a knife and your fist, or a meat pounder or heavy mug (I put mine in a plastic bag to contain the splatter).
In a good-sized Dutch oven, melt the butter over medium (medium-low if using a cast iron or enameled cast iron pot). Add the onions and saute until softened, about 5 minutes. Add the milk, garlic and Dijon and bring to a boil over medium. Add a generous amount of salt and pepper.
Add the potatoes and allow to simmer until they are nearly tender, about 10 minutes.
Using a slotted spoon, and discarding the milk once you’re done, transfer half the potatoes and onions to your greased baking dish, then cover with half of the cheese. Repeat, seasoning generously with salt and pepper, then spoon the potatoes and onions into the dish in a second layer and top with the remaining cheese. Season again, then pour the cream evenly over the top.
Bake uncovered for 50 minutes to one hour, or until the cheese is crispy and golden. Let cool a few minutes and serve!

This is actually easy enough to do for a regular weeknight dinner, and would definitely give you enough to use a second time in one week (unless you have a family of teenage boys, in which case, I can’t help you! And hats off, my friend). I used packaged shredded cheddar this time around, but you could grate fresh — I just can’t deal with that stress on my wrists, which still battle some carpal tunnel syndrome left over from my pregnancy. And, of course, another type of cheese (gruyere? hmm) will do just fine.
If you prefer, you can use another kind of milk — almond, soy, etc. — and you can substitute 2 cups of milk and 2 cups of water for the full 4 cups of whole milk called for. Many recipes also call for heavy cream in scalloped potatoes, but I don’t find that to be necessary. You can still get a very rich effect by using light cream as I did here. Some recipes also call for cooking the potatoes on lower heat for longer in the oven, but I like how this recipe recommends par-cooking on the stove top before you place them in the oven to ensure they are adequately and evenly seasoned. You can always save the discarded milk for another culinary use. And, if you’re interested, I used russet potatoes here; I was looking for yukon gold, but they weren’t available so I decided to try my luck and I’m pleased with the result. These held up very well structurally. If you want a tremendously thick sauce in the dish, you could thicken your milk with flour at the par-cooking stage.
I really hope you like this recipe and that it broadens your taste buds if you grew up accustomed to the boxed version! These made great leftovers with some of the spiral ham and casseroles we had on Christmas. Georgia ate them enthusiastically, but then again the main ingredients are cheese, milk and potatoes, so I’m not surprised. The onion and garlic lend a visible flavor but don’t overwhelm, making them perfect for picky eaters while still being a little more interesting than mashed potatoes. Enjoy!
