- Dijon mustard – adds a little tang and sharpness to cut through the richness.

Step-By-Step Instructions to Make Sheet Pan Scalloped Potatoes:
Step 1: Prepare the sheet pan
First, you’ll want to get your sheet pan ready by coating it with nonstick spray so nothing sticks later. This step makes cleanup easier and also helps the potatoes crisp up nicely on the bottom.
Step 2: Cook the onions
Next, heat a skillet with a little butter and oil, then add the diced onion. Let them cook slowly until they turn soft and translucent. The onions should smell sweet and mellow, and they’ll give the sauce a nice base flavor.
Step 3: Slice and arrange the potatoes
While the onions are cooking, slice the potatoes thinly and pat them dry. Then, lay them out on the sheet pan in overlapping rows, almost like shingles. This helps them cook evenly and soak up the sauce later.
Step 4: Add the first layer of cheese
Sprinkle some of the Gruyere and Parmesan over the potatoes. This first layer melts down into the slices and adds flavor right from the start.
Step 5: Make the cream mixture
Once the onions are ready, stir in the cream, Dijon mustard, and herbs. Keep stirring until the mixture looks smooth and glossy, just before it starts bubbling. This sauce will coat the potatoes and make them creamy.
Step 6: Pour the sauce over the potatoes
Carefully pour the cream and onion mixture over the potatoes on the sheet pan. Tilt the pan slightly so the sauce spreads to the edges and corners. You want every slice to be coated so the flavor is even.
Step 7: Add the final cheese topping
Sprinkle the remaining Gruyere and Parmesan on top. This layer will melt and turn golden in the oven, giving the dish a bubbly, cheesy crust.
Step 8: Bake until golden and bubbly
Cover the pan with foil for the first part of baking, then remove it so the top can brown. The potatoes should be tender, the edges crispy, and the cheese melted into a golden crust.
Step 9: Rest before serving
After baking, let the potatoes sit for a short while before serving. This helps the sauce settle and makes it easier to scoop without falling apart.

Helpful Tips For The Best Results:
Potato texture: Slice the potatoes thin and keep them even in size, because this helps them cook through at the same time and makes the dish creamy without leaving hard pieces.
Heat control: Start the oven hot to get the edges crisp, then lower the temperature so the middle cooks gently and the sauce stays smooth instead of burning.
Cheese layering: Add cheese in two stages, because the first layer melts into the potatoes and the second layer gives that golden crust on top.
Sauce consistency: Stir the cream mixture until it looks glossy and smooth, since this makes sure it spreads evenly over the potatoes.
Ingredient swap: If you don’t have Gruyere, you can use Swiss or Jarlsberg, and if you want a lighter option, you can replace some cream with milk.
Tasty Variations to Try:
- Extra flavor: Add garlic or a pinch of nutmeg to the cream mixture for a stronger taste.
- Herb swap: Instead of rosemary or thyme, try parsley or chives for a fresher flavor.
- Cheese change: Use cheddar or mozzarella if you prefer a milder or more stretchy cheese topping.
- Dietary option: For a lighter version, swap half the cream with plain yogurt or low-fat milk.
- Seasonal idea: Mix in roasted vegetables like bell peppers or zucchini during summer, or add cooked bacon bits in winter for a heartier dish.
- Spice kick: Sprinkle a little chili powder or paprika on top before baking if you want a bit of heat.
Serving Suggestions:
1. Holiday meals:
Sheet Pan Scalloped Potatoes are perfect for big occasions like Thanksgiving or Christmas, because they make enough to feed a group and look nice on the table alongside turkey or ham.
2. Weeknight dinners:
Serve with baked salmon or roasted chicken when you want something filling but easy, since the creamy potatoes balance lighter proteins really well.
3. Special gatherings:

4. Casual meals:
You can even serve them with burgers or simple grilled meat, since the potatoes add a comforting side without needing much extra effort.
Storage & Reheating Tips:
- How long it keeps: Sheet Pan Scalloped Potatoes can be stored in the fridge for a few days, and they usually stay good for about three to four days if covered properly.
- Best storage method: Place leftovers in an airtight container or cover the sheet pan tightly with foil, because this helps keep the potatoes from drying out.
- Simple reheating advice: Warm them in the oven until the cheese looks melted again and the edges turn slightly crisp, or use the microwave if you just need a quick reheat.
