Ingredients

4 russet potatoes (about 2 lbs), peeled and sliced 1/4 inch thick
1 yellow onion, sliced into rings
3 tbsp unsalted butter
3 tbsp all-purpose flour
1/2 tsp kosher salt
2 cups whole milk, room temperature
1 1/2 cups shredded mild cheddar cheese
Salt and pepper to taste

How to Make It

Preheat oven to 400°F. Lightly grease an 8×8-inch or 2-quart baking dish.
Layer half the potatoes and onions in the dish. Repeat with the remaining potatoes and onions.
In a medium saucepan, melt butter over medium heat. Whisk in flour and kosher salt; stir constantly for 1 minute.
Slowly pour in milk, whisking to prevent lumps. Cook, stirring often, until thickened and smooth.
Add cheddar cheese all at once and stir until fully melted (about 30–60 seconds).
Pour cheese sauce evenly over layered potatoes and onions.
Cover dish with foil and bake for 85–90 minutes, or until potatoes are fork-tender.
For a crispy, golden top, broil uncovered for 2–4 minutes at the end.
Let rest for 5–10 minutes before serving. Season with additional salt and pepper to taste.

Tips for Perfect Scalloped Potatoes

Slice potatoes evenly so they cook at the same rate.
Room temperature milk blends better into the sauce without curdling.
You can prep this dish a few hours ahead—just refrigerate before baking.
Try swapping in Gruyère or sharp cheddar for a flavor twist.

Comfort in Every Bite

I first made these cheesy scalloped potatoes for a Thanksgiving potluck, and they disappeared before I could even grab a second scoop. Now, it’s my go-to when I want something cozy and reliable. The rich, creamy potatoes and melty cheese never fail to deliver that warm, “just like home” feeling.

What to Serve with Cheesy Scalloped Potatoes

They’re perfect alongside roast chicken, baked ham, grilled steak, or a veggie main. Add a crisp green salad or sautéed green beans to balance the richness. They’re also a fabulous addition to your holiday table.

How to Store and Reheat

Let leftovers cool completely, then store in an airtight container in the fridge for up to 4 days. Reheat in the oven at 350°F covered with foil, or in the microwave for individual servings. Add a splash of milk if needed to refresh the sauce.

FAQs

Can I make this ahead of time?

Yes! Assemble fully, cover, and refrigerate up to 24 hours before baking.
