Ingredients & Substitutions
Yukon Gold or Russet Potatoes: You will need 3 lbs (1.36kg) of potatoes, scrubbed and peeled. Starchy potatoes are essential for creating the thick, creamy sauce naturally as they bake.
Unsalted Butter & All-Purpose Flour: Use 1/4 cup (56g) of butter and 1/4 cup (30g) of flour. This creates the foundational roux that thickens your luscious off-white bubbly cheese sauce.
Whole Milk & Heavy Cream: A blend of 2 cups (480ml) whole milk and 1 cup (240ml) heavy cream provides maximum richness. The dairy proteins are crucial for achieving that glossy melted cheese consistency.
Garlic & Nutmeg: Mince 3 cloves (15g) of fresh garlic and add 1/2 tsp (1g) of ground nutmeg. These invisible foundational ingredients elevate the savory depth of the cream sauce.
Kosher Salt: Use 1.5 tsp (9g) of kosher salt to properly season the potatoes. Proper salting is scientifically required to break down the potato starches and bring out their earthy flavor.
Mixed Cheeses (Gruyere & Sharp White Cheddar): Shred 2 cups (226g) of Gruyere and 1.5 cups (170g) of sharp white cheddar. White cheeses are specifically chosen to maintain the beautiful off-white color of the creamy sauce while ensuring a golden-brown melted crust.
Fresh Green Parsley & Coarse Black Pepper: Reserve 2 tbsp (7g) of finely chopped fresh green parsley and 1 tsp (2g) of coarse black pepper. These are scattered evenly across the blistered cheese surface for a pop of color and bite.
Equipment Needed
- Mandoline Slicer: Crucial for getting perfectly uniform, thinly sliced potatoes that cook evenly.
- Rustic White Ceramic Oval Casserole Dish: Provides excellent heat retention and presents the gorgeous glossy melted cheese beautifully.
- Heavy-Bottomed Saucepan: Necessary for gently cooking the roux and preventing the dairy from scorching.
- Cheese Grater: Always grate your mixed cheeses from a block for the best melting quality.
Step-by-Step Instructions
1. Prepare the Potatoes
Begin by preheating your oven to 400°F (200°C). Peel the 3 lbs (1.36kg) of potatoes and use a mandoline to cut them into uniformly thin slices, about 1/8-inch (3mm) thick. Do not rinse the sliced potatoes, as you want to preserve their natural starches to help thicken the sauce.
2. Build the Creamy Off-White Cheese Sauce
In your heavy-bottomed saucepan, melt the 1/4 cup (56g) of unsalted butter over medium heat. Whisk in the 1/4 cup (30g) of all-purpose flour and cook for 1-2 minutes until it smells lightly toasted but hasn’t darkened. Slowly whisk in the 2 cups (480ml) of whole milk and 1 cup (240ml) of heavy cream until smooth.
3. Season and Thicken
Add the minced garlic, ground nutmeg, and kosher salt to the simmering liquid. Stir continuously until the sauce coats the back of a spoon. Remove from heat and stir in 1 cup (113g) of the Gruyere and 1/2 cup (56g) of the white cheddar until you have a thick, creamy, off-white bubbly cheese sauce.
4. Assemble the Layers
Grease your rustic white ceramic oval casserole dish with a little butter. Create a base foundation of tightly overlapping, thinly sliced potatoes. Pour one-third of your creamy cheese sauce over the potatoes, spreading it evenly. Repeat this layering process two more times, finishing with a final layer of sauce.
5. Bake the Potatoes
Cover the casserole dish tightly with aluminum foil. Bake for 40-45 minutes until the potatoes are mostly tender when pierced with a knife. This enclosed steam helps the potatoes cook without drying out or burning the dairy.
6. Create the Melted Golden-Brown Cheese Crust
Remove the foil and sprinkle the remaining mixed cheeses evenly across the top layer. Return the dish to the oven, uncovered, for another 15-20 minutes. Watch closely for sensory cues: you want to hear the edges bubbling vigorously and see a beautifully golden-brown, charred, and melted crust forming.
7. Broil and Garnish
For the ultimate visual appeal, turn on the oven’s broiler for 1-2 minutes until you achieve distinct blistered cheese patches. Remove from the oven and let it rest for 15 minutes to allow the glossy melted cheese to set. Finally, scatter the finely chopped fresh green parsley and tiny specks of coarse black pepper evenly across the blistered cheese surface.
Expert Tips for Success
- Keep the Starch: Never soak your potato slices in water. The residual starch is the secret, invisible ingredient that binds with the dairy to create a thick, luscious sauce.
- Grate Your Own Cheese: Pre-shredded bagged cheeses contain anti-caking agents that prevent a smooth melt. Grating fresh ensures the perfect off-white bubbly cheese sauce.
- Overlap Carefully: Taking the time to build tightly overlapping layers ensures structural integrity, making it easy to slice and serve beautiful portions.
- Let It Rest: Slicing into the hot dish immediately will result in a runny sauce. Resting allows the starches to re-absorb liquid, solidifying that gorgeous, glossy texture.
- Watch the Broiler: The broiler works quickly. Stay by the oven to ensure you get perfectly blistered cheese patches without completely burning the crust.
Storage & Reheating/Freezing
Store any leftover Homemade Scalloped Potatoes in an airtight container in the refrigerator for up to 4 days. When reheating, place individual portions in the microwave, or reheat the entire casserole dish in a 350°F (175°C) oven covered with foil until warmed through.
While you can freeze scalloped potatoes for up to 2 months, note that the dairy may separate slightly upon thawing. To freeze, let the dish cool completely, wrap it tightly in plastic wrap and heavy-duty aluminum foil. Thaw overnight in the fridge before reheating gently in the oven.
What to Serve With This

Frequently Asked Questions
Yes! You can assemble the tightly overlapping sliced potatoes and pour the cheese sauce over them up to a day in advance. Store the covered rustic white ceramic oval casserole dish in the fridge, and add 10-15 extra minutes to the initial covered bake time when ready to cook.
Peeling is highly recommended for homemade scalloped potatoes. It ensures a smooth, tender bite that blends perfectly with the off-white bubbly cheese sauce without tough, stringy skins getting in the way.
To get perfectly blistered cheese patches, bake the dish uncovered for the last 15-20 minutes, then switch your oven to the broiler setting for 1-2 minutes. Keep a close eye on it so the mixed cheeses char beautifully without burning.
Traditionally, scalloped potatoes are baked in a cream sauce without cheese, while potatoes au gratin include cheese. However, modern homemade scalloped potatoes often feature a decadent, creamy cheese sauce and a melted golden-brown cheese crust to maximize flavor.
Dairy can curdle if it gets too hot or if the acidity is unbalanced. Using a roux (butter and flour) stabilizes the thick, creamy, off-white sauce, and baking it initially covered with foil prevents the dairy from scorching and separating.
