Au gratin potatoes take scalloped potatoes to the next level with sharp Gruyere and Parmesan melted between every layer. The broiled cheese crust on top is the best part.
French cuisine teaches us that mastering a few fundamental techniques can transform simple ingredients into something extraordinary. This recipe proves that point beautifully.
This version of Cheesy Au Gratin Potatoes has been refined through testing to ensure consistently excellent results. A great side dish does not compete with the main course — it makes everything around it better. This recipe brings enough personality to stand on its own while complementing whatever protein or centerpiece you pair it with.
Ingredients
- 3 lbs Yukon Gold potatoes, thinly sliced
- 2 cups shredded Gruyere cheese
- 1.5 cups heavy cream
- 2 tbsp butter
- 2 tbsp all-purpose flour
- 1/2 cup grated Parmesan cheese
Instructions
- 1
Melt butter in a saucepan, whisk in flour, cook 1 minute. Gradually whisk in cream and cook until thickened, about 3 minutes.
- 2
Remove from heat and stir in 1.5 cups Gruyere, salt, pepper, and a pinch of nutmeg until melted.
- 3
Layer one-third of the potatoes in a greased baking dish, top with one-third of the cheese sauce. Repeat twice.
- 4
Sprinkle remaining Gruyere and Parmesan on top. Cover with foil and bake at 375°F for 45 minutes.
- 5
Remove foil and broil 3-5 minutes until the cheese is deeply golden and bubbly.
Serving Suggestions
Ways to Serve This Dish
Serve alongside a fresh baguette and salted butter
Pair with a crisp green salad with Dijon vinaigrette
Serve with classic coleslaw and cornbread on the side
Pair with fresh-cut fries or roasted potato wedges
Substitutions
GruyereSharp cheddar or fontina
Both melt beautifully but offer different flavor profiles
Heavy creamWhole milk with 2 tbsp extra butter
Slightly less rich but still creamy
RiceQuinoa or cauliflower rice
Quinoa adds more protein and a slightly nutty flavor. Cauliflower rice is the lightest option — saute it briefly to remove excess moisture before using.
Tips & Storage
Pro Tips
Pat potato slices dry to prevent a watery casserole.
Let it rest 10 minutes after baking so the sauce sets and slices cleanly.
Let the protein rest for 5-10 minutes after cooking to allow the juices to redistribute for maximum tenderness.
Season each component individually rather than seasoning at the end — this builds deeper, more complex flavor throughout.
Storage
Store leftovers in an airtight container in the refrigerator for up to 4 days. For longer storage, freeze individual portions in freezer-safe containers for up to 3 months. Label with the date and recipe name.
Reheating
Reheat at 350°F for 20 minutes until bubbly, then broil briefly to re-crisp the top.
Recipe Notes from Our Kitchen
Editor's Note
Editor's note: Season assertively. Side dishes that taste perfectly seasoned on their own will complement the main course rather than fading into the background of the plate.

Frequently Asked Questions
- Can I use cheddar instead of Gruyere?
- Sharp cheddar works well but has a different flavor profile than the traditional nutty Gruyere.
- Can I assemble the night before?
- Yes—cover with plastic wrap and refrigerate. Add 10-15 minutes to the bake time.
- Can I make this ahead?
- Yes. Most side dishes hold well for up to 2 days in the refrigerator. Reheat in the oven at 350 degrees for 10 to 15 minutes, or on the stovetop over medium heat. Add a splash of water or oil if needed to refresh the texture.
- Can I freeze this?
- Cooked grains, roasted vegetables, and most cooked sides freeze well for up to 2 months. Cool completely first, then portion into freezer bags and press out the air. Raw salads and delicate preparations do not freeze well.
