Ingredients for Creamy Scalloped Potatoes
This recipe serves 6 to 8 people.
Ingredients (U.S. and Metric)
• 3 lbs Yukon Gold potatoes (1.4 kg)
• 2 tbsp bacon grease (30 g)
• 1 large onion, finely chopped (about 380 g)
• 4½ tbsp all-purpose flour (36 g)
• 2 cups whole milk (500 ml)
• 1 cup heavy cream (250 ml)
• ¼ tsp white pepper (1 g)
• ½ tsp Dijon mustard (2–3 g)
• 1/8 tsp nutmeg (0.5 g)
• Fresh thyme leaves from several sprigs
• 2 garlic cloves, minced (6 g)
• 1 tbsp Worcestershire sauce (15 ml)
• Salt and black pepper to taste
Step-by-Step: How to Make Creamy Scalloped Potatoes Recipe from Scratch
Step 1: Caramelize the Onions
Begin by heating the bacon grease in a large skillet over medium heat.
Add the chopped onion and cook slowly until the onions soften and begin to caramelize. Stir occasionally to prevent burning and allow the natural sugars in the onions to develop.
Once the onions are nearly finished cooking, add the minced garlic and cook for about 30 seconds until fragrant.
This step builds the savory flavor foundation for the entire dish.
Step 2: Infuse the Milk and Cream
Pour the whole milk and heavy cream into the skillet with the onions.
Add the following ingredients:
• White pepper
• Dijon mustard
• Nutmeg
• Worcestershire sauce
• Fresh thyme leaves
• Salt and black pepper
Allow the mixture to gently heat and simmer for several minutes. This allows the herbs and spices to infuse into the dairy and creates a richer flavor for the sauce.
Remove the mixture from heat once the flavors have infused.
Step 3: Slice the Yukon Gold Potatoes
Peel the Yukon Gold potatoes and slice them into thin rounds about ⅛ inch (3 mm) thick.
Consistent slices are important so the potatoes cook evenly in the oven and absorb the cream sauce properly.
A mandoline slicer works well for this step.
Step 4: Make the Creamy Sauce
Return the skillet to medium heat and sprinkle the all-purpose flour into the onion mixture.
Stir continuously so the flour combines with the bacon grease and onions to form a roux.
Cook the roux for about 1–2 minutes to remove the raw flour taste.
Gradually stir the infused milk and cream mixture back into the pan. Continue stirring until the sauce thickens into a smooth, creamy consistency.
The sauce should coat the back of a spoon but still be pourable.
Step 5: Layer and Bake the Scalloped Potatoes
Lightly grease a baking dish.
Begin layering the ingredients:
Add a layer of sliced potatoes
Spoon some of the creamy sauce over the potatoes
Spread some of the onions across the layer
Repeat until all the potatoes and sauce are used.
Make sure the top layer is fully coated with sauce.
Cover the dish with foil and bake at 375°F (190°C) for 45 minutes.
Remove the foil and continue baking 20–30 minutes longer until the potatoes are fork-tender and the top begins to turn golden.
Let the Dish Rest Before Serving
Once the scalloped potatoes come out of the oven, allow them to rest 10 to 15 minutes before serving.
This allows the sauce to thicken slightly and makes the dish easier to portion.
Why Yukon Gold Potatoes Are Best for a Scalloped Potatoes Recipe
Yukon Gold potatoes are the best choice for this recipe because they:
• Have a naturally buttery flavor
• Hold their shape during baking
• Create a creamy texture without becoming mushy
Their medium starch content makes them ideal for creamy baked potato dishes.
Scalloped Potatoes vs Potatoes Au Gratin
These two dishes are often confused.
Scalloped potatoes are baked in a creamy milk-based sauce.
Potatoes au gratin include cheese between the layers and on top.
This recipe follows the traditional classic scalloped potatoes method without cheese.
What to Serve with Scalloped Potatoes
Creamy scalloped potatoes pair well with many main dishes, including:
• Roast chicken
• Holiday ham
• Pork chops
• Prime rib
• Thanksgiving turkey
Because of their rich flavor, they are one of the most popular holiday side dishes in the United States.
