What Is Cheddar Potato Gratin?
A potato gratin (sometimes called potatoes au gratin) is a classic baked potato dish layered with cream and cheese, then baked until tender and golden.
Traditional French gratins often use Gruyère cheese, but this version leans into sharp cheddar for a rich, comforting flavor.
Unlike scalloped potatoes, which typically rely more on cream and less on cheese, this potato gratin with cheddar cheese has distinct cheesy layers that create that irresistible golden crust on top.

The Secret to Perfect Potato Gratin
There are three simple secrets to making the best Yukon gold potato gratin:
1. Use Yukon Gold Potatoes
Yukon golds are naturally buttery and hold their shape beautifully while still becoming tender. They give the gratin a creamy texture without falling apart.
2. Slice the Potatoes Thin and Even
Aim for about 1/8-inch thick slices. Even slicing ensures the potatoes cook evenly and become perfectly tender in the oven.
3. Simmer Before Baking
Bringing the potatoes and half-and-half to a gentle boil before baking jump-starts the cooking process. This guarantees tender potatoes and prevents a watery sauce.
This simple step makes all the difference.
Ingredients You’ll Need
For this cheddar potato gratin, you only need:
- Yukon gold potatoes
- Half-and-half
- Salt
- Cayenne pepper (optional, but recommended)
- Sharp cheddar cheese
- Fresh chives
How to Make Cheddar Potato Gratin
Step 1: Preheat and Prepare Your Baking Dish
Preheat your oven to 350°F. Lightly coat a shallow 3-quart baking dish with cooking spray to prevent sticking and make cleanup easier.
Step 2: Slice the Potatoes
Peel your Yukon gold potatoes and slice them thinly — about 1/8 inch thick. Even slices are important so the potatoes cook evenly and become perfectly tender.
(If you have a mandoline slicer, this is a great time to use it.)
Step 3: Simmer the Potatoes in Cream
In a large pot, combine:
- Sliced potatoes
- Half-and-half
- Salt
- Cayenne pepper (if using)
Bring the mixture to a gentle boil over medium heat, stirring occasionally so nothing sticks to the bottom.
Once it reaches a boil, remove from heat. This step jump-starts the cooking process and ensures your cheesy potato gratin bakes up tender instead of under cooked.
Step 4: Layer the First Half
Using a slotted spoon, transfer half of the potatoes into your prepared baking dish.
Sprinkle evenly with:
- 1 cup shredded cheddar cheese
- 2 tablespoons chopped chives
This creates a rich, cheesy middle layer that gives the gratin its signature flavor.
Step 5: Add Remaining Potatoes
Layer the remaining potatoes on top.
Then carefully pour the remaining half-and-half mixture from the pot evenly over the potatoes. This keeps everything moist and creamy while baking.
Step 6: Top with Cheese
Sprinkle the remaining cheddar cheese evenly over the top.
This final layer will bake into that beautiful golden crust everyone loves in a classic potato gratin with cheddar cheese.
Step 7: Bake Until Golden and Tender
Place the baking dish in the oven and bake for 45–50 minutes, or until:
- The potatoes are fork tender
- The top is golden brown
- The edges are bubbling
If you’d like a deeper golden finish, broil for the last 2–3 minutes — just watch it carefully.
Step 8: Finish with Fresh Chives
Remove from the oven and let the gratin rest for about 10 minutes. This helps the cream settle slightly so it slices more neatly.
Sprinkle with the remaining 2 tablespoons of fresh chopped chives before serving.
And that’s it, a rich, creamy, perfectly golden cheddar potato gratin ready for your holiday table or Sunday dinner.
Make-Ahead Instructions
This is a wonderful holiday potato side dish because it can be assembled ahead of time.
To prep ahead:
- Assemble the gratin fully (but do not bake).
- Cover tightly and refrigerate up to 24 hours.
- Allow to sit at room temperature for 20–30 minutes before baking.
- Bake as directed, adding 5–10 extra minutes if needed.
This makes holiday cooking so much easier.

Frequently Asked Questions
