This dish brings together 2 lbs Yukon Gold potatoes that are peeled and thinly sliced with melted cheddar, Gruyere, and Parmesan cheese to create a irresistibly rich experience.
I also add 2 cloves of minced garlic, 1 cup heavy cream, and 1 cup whole milk which blend perfectly with a sprinkle of 1 teaspoon salt, 1/2 teaspoon black pepper, and 1/2 teaspoon dried thyme. When baking, I grease the dish with 2 tablespoons melted butter.
There is something special about creating a dish that is easy to make and works so well as a side dish on holidays or any day you need a comforting vegetarian option. Trust me when I say that every bite is full of cheesy goodness that will keep you coming back for more.

FAQ
Dad’s Creamy & Cheesy Au Gratin Potatoes Recipe Substitutions and Variations
- Yukon Gold potatoes can be swapped with russet potatoes. They’ll work pretty well in texture even though they are a bit starchier
- If you don’t have heavy cream around, try mixing 3/4 cup half-and-half with 1/4 cup melted butter. It ain’t exactly the same but gets close enough
- No whole milk? You can use a lighter milk like 2% instead. Your dish might be a bit less rich but it’ll still taste good
- For the shredded sharp cheddar, colby jack is a decent alternative if you want a milder flavor
- If Gruyere isn’t available, Swiss cheese can be used and still give you that nice, nutty flavor
Pro Tips
1. Make sure you slice the potatoes as evenly as possible so that they cook all at once; uneven slices can cause some parts to be mushy while others come out undercooked.
2. Let the dish sit for a few minutes after you take it out of the oven, so that the cheese and layers set up well before you dig in, it helps the flavors really come together.
3. Try adding a pinch of nutmeg or even some smoked paprika into the cream mixture for a little bonus flavor that makes the dish feel a bit more gourmet.
4. When layering the cheese, be generous but try not to overdo it; too much cheese without enough cream might leave you with a greasy topping as opposed to that perfect golden, crispy finish.
