This is comfort food at its finest – the kind of dish that makes people lean back in their chairs with satisfied sighs and immediately ask for the recipe.

Ingredients
For the aromatic base
- 2 tablespoons unsalted butter
- 1 medium onion, 1/4-inch diced
- 6 garlic cloves, minced (about 2 tablespoons)
For the creamy sauce
- 1 cup whole milk
- ¾ cup low sodium chicken broth or vegetable broth
- 1 ½ teaspoons kosher salt, divided
- ½ teaspoon ground black pepper
For the layers
- 3 pounds Yukon Gold potatoes (about 6 to 8 medium potatoes)
- 3 tablespoons all-purpose flour
- 2 cups 1/4 to 1/2-inch diced cooked ham
- 4 ounces sharp cheddar cheese, shredded (about 1 cup)
- 2 tablespoons finely grated Parmesan cheese
For serving
- Chopped fresh chives, thyme, or parsley (optional)
Instructions
Preparation
- 1 Place a rack in the center of your oven and preheat to 375°F (190°C). Coat a 9×13 inch casserole dish with nonstick spray and set aside. This ensures even cooking and prevents sticking.
- 2 In a medium pot or cast iron skillet with high sides, melt the butter over medium-low heat. Add the diced onion and cook for 8 to 10 minutes, stirring often with a silicone spatula, until translucent. The key here is patience – adjust the heat as needed so the onion softens but does not brown, which would add bitter notes to your creamy sauce.
- 3 Stir in the minced garlic and cook just until fragrant, about 1 minute more. You’ll know it’s ready when the kitchen fills with that irresistible aroma of sautéed garlic.
Making the sauce
- 4 Turn off the heat completely. Stir in the milk, broth, 1 teaspoon of the salt, and the black pepper using a whisk to ensure everything combines smoothly. Set this mixture aside – it will be the creamy foundation that transforms your potatoes into pure comfort food magic.
Preparing the potatoes
- 5 Peel the potatoes using a sharp knife or vegetable peeler. With a mandoline slicer (this truly is the easiest method for uniform slices!) or a sharp chef’s knife, carefully cut the potatoes into very thin slices (about 1/8-inch thick). Don’t cut them any thicker or they may not cook through properly, leaving you with crunchy potato disappointment.
- 6 Place the potato slices in a large mixing bowl and sprinkle with the flour and remaining 1/2 teaspoon salt. With clean hands, toss everything together until each slice is lightly coated. The flour will help thicken the sauce as it bakes.
Assembly
- 7 Spread one-third of the sliced potatoes in an even layer in the bottom of your prepared dish. Spoon 1 cup of the milk-broth mixture over the top, ensuring it reaches the edges. Sprinkle with 2/3 cup of the diced ham and one-third of the shredded cheddar cheese.
- 8 Repeat the layering process twice more, so you have 3 complete layers each of potato, milk-broth mixture, ham, and cheddar cheese. You’ll end with a beautiful layer of melted cheddar on top.
Baking
- 9 Lightly mist a large piece of aluminum foil with nonstick spray. Cover the dish with the foil, placing it spray-side down to prevent sticking, and bake for 35 minutes. This covered baking time allows the potatoes to steam and become tender.
- 10 Remove the foil and bake for an additional 25 minutes uncovered. The top should be starting to turn golden and the liquid should be bubbling around the edges.
Finishing touches
- 11 Remove the dish from the oven and sprinkle with the finely grated Parmesan cheese. Turn your oven to broil and return the pan to the oven. Broil until the cheese is golden brown and bubbly, about 1 to 3 minutes. Keep a close eye on it during this step – broilers work fast and you don’t want to go from golden perfection to charcoal disaster!
- 12 Sprinkle with fresh herbs if using. Allow the dish to stand at room temperature for 20 to 25 minutes to allow the milk mixture to set and thicken properly. This resting time is crucial – it’s what transforms your casserole from soupy to perfectly creamy. Serve hot with additional salt and pepper to taste, keeping in mind that the saltiness will vary based on your ham and broth choices.

Easter and Christmas celebrations benefit from its crowd-pleasing nature, while cozy winter dinners showcase its warming, stick-to-your-ribs qualities.
Pro Tips and Troubleshooting
Professional Techniques
The key to perfect scalloped potatoes lies in achieving uniform potato slices – invest in a mandoline slicer or take extra time with your knife work. Salt the potato layers as you build them; this seasons throughout and helps draw out excess moisture. Don’t skip the resting period after baking – those 20-25 minutes allow the starches to set and create the perfect creamy-but-not-soupy consistency that separates amateur from professional results.
Common Mistakes and Solutions
Watery results usually stem from skipping the flour coating or not allowing proper resting time. Crunchy potatoes indicate slices were too thick or oven temperature was too high. Curdled sauce happens when dairy gets too hot too fast – always remove from heat before adding milk and broth. Burnt top with undercooked interior means your oven rack was too high; center position is crucial for even cooking.
Storage and Reheating
Refrigerate leftovers for up to 4 days in the original baking dish, covered tightly. Reheat individual portions in the microwave at 50% power to prevent overcooking the edges. For best texture, reheat larger portions in a 300°F (150°C) oven for 20-25 minutes, covered with foil. Freezing works for up to 3 months – thaw completely before reheating and expect slightly softer texture.
Make-Ahead Strategies
Assemble completely up to 24 hours ahead, cover tightly, and refrigerate. Add 10-15 minutes to the initial covered baking time when cooking from cold. Pre-slice potatoes up to 4 hours ahead and store in cold water with a splash of lemon juice to prevent browning – drain and pat dry before using.
Scaling Tips
Double the recipe easily using two 9×13 pans or one large roasting pan. Half portions work well in an 8×8 square pan with slightly reduced cooking time. For crowds, consider multiple smaller pans rather than one enormous dish for more even cooking and easier serving.
This recipe proves that the best comfort foods don’t need complicated techniques or exotic ingredients – just quality basics treated with care and attention. Every forkful delivers that perfect combination of creamy potatoes, savory ham, and melted cheese that makes this dish a guaranteed crowd-pleaser for any occasion.
