Ingredients
| Main Ingredients | Quantity | Notes |
| Yukon Gold Potatoes | 3 pounds | Peeled and sliced 1/8-inch thick |
| Cooked Ham | 1.5 pounds | Cut into thick cubes |
| Gruyère Cheese | 1 1/2 cups | Freshly grated |
| Sharp Cheddar Cheese | 1 cup | Freshly grated |
| Fresh Parsley | 2 tablespoons | Finely chopped for garnish |
| Cream Sauce | Quantity | Notes |
| Unsalted Butter | 3 tablespoons | For the roux |
| All-Purpose Flour | 3 tablespoons | Thickening agent |
| Heavy Whipping Cream | 1 1/2 cups | Room temperature |
| Whole Milk | 1 cup | Room temperature |
| Garlic Cloves | 3 large | Minced |
| Fresh Thyme | 1 teaspoon | Finely chopped |
| Kosher Salt | 1 teaspoon | Essential for seasoning |
| Black Pepper | 1/2 teaspoon | Freshly cracked |
Step-by-Step Instructions
- Preheat the Oven: Set your oven to 375°F (190°C). Generously grease a 9×13 inch oval or rectangular baking dish with non-stick spray or softened butter.
- Make the Cream Sauce: Melt the butter in a medium saucepan over medium heat. Add the minced garlic and cook for one minute until fragrant. Whisk in the flour and cook for one additional minute to form a light paste. Gradually whisk in the heavy cream and milk until completely smooth.
- Simmer and Season: Bring the liquid to a gentle simmer. Stir in the fresh thyme, kosher salt, and black pepper. Let the sauce thicken slightly for about 3 minutes, then remove the saucepan from the heat and set it aside.
- Assemble the Casserole: Arrange the thinly sliced potatoes in the prepared baking dish, standing them up slightly in a shingled pattern. Nestle the thick cubes of ham evenly between the potato slices throughout the entire dish.
- Bake to Perfection: Pour the warm cream sauce evenly over the potatoes and ham. Cover the dish tightly with aluminum foil and bake for 45 minutes. Remove the foil, sprinkle the grated Gruyère and Cheddar cheese evenly over the top, and bake uncovered for another 25 to 30 minutes until the potatoes are fork-tender and the cheese is golden and bubbling. Garnish with fresh parsley before serving.
Best Tips
Slicing the potatoes to an identical thickness is the ultimate secret to ensuring they all cook evenly in the rich cream sauce.
Always grate your cheese directly from a fresh block, as pre-shredded cheese is coated in anti-caking powders that will prevent it from melting smoothly.
Let the baked casserole rest on your kitchen counter for at least fifteen minutes before serving so the bubbly cream sauce has time to thicken and set.
Best Ingredient Options
| Ingredient | Substitution | Notes |
| Yukon Gold Potatoes | Russet Potatoes | Russets contain more starch, which creates a thicker sauce |
| Cooked Ham | Smoked Sausage | Slice into thick coins for a delicious flavor twist |
| Gruyère Cheese | Swiss Cheese | Provides a similar nutty, classic melting profile |
Recipe Variations
If you want to incorporate more vegetables into your easy dinner recipes, tuck fresh broccoli florets or chopped asparagus spears between the potatoes before baking.
For a fantastic spicy kick, add half a teaspoon of cayenne pepper or a generous splash of your favorite hot sauce directly into the simmering cream mixture.
You can easily make a vegetarian version of this hearty casserole by omitting the meat entirely and layering in deeply caramelized onions and roasted mushrooms instead.
What to Serve With
Because this baked dish is exceptionally rich and heavy, it pairs perfectly with a crisp, acidic side dish like a mixed green salad tossed in a sharp lemon vinaigrette.
For a highly satisfying and complete family meal, serve generous scoops alongside some simple oven-roasted green beans or garlic-buttered carrots.
Do not forget to provide warm, crusty artisan bread or soft dinner rolls to soak up every last drop of the incredible cheese sauce left on your plate.
Make-Ahead Instructions
You can assemble the entire casserole up to twenty-four hours in advance to make your evening meal prep completely stress-free.
Follow all the assembly instructions, but do not bake it. Cover the dish tightly with plastic wrap or aluminum foil and store it in the refrigerator.
When you are ready to cook, allow the cold dish to sit on the counter for thirty minutes to take the chill off before placing it into the hot oven.
Storage
Allow any leftover portions to cool completely to room temperature before transferring them into a shallow, airtight storage container.
Store the container in the refrigerator, where this delicious baked casserole will remain fresh and perfectly safe to eat for up to four days.
The cream sauce will thicken significantly as it chills, but it will beautifully regain its silky texture once properly warmed.
Reheating
The absolute best way to reheat this meal without separating the dairy is to place individual portions in a baking dish and cover them with aluminum foil.
Warm them in a 350°F (175°C) oven for about fifteen minutes, or until the center is steaming hot and the cheese is soft again.
If you must use a microwave, heat your portion on medium power in one-minute bursts, adding a tiny splash of milk to help rehydrate the rich sauce.
Freezing
We strongly advise against freezing this completed dish, as dishes heavily reliant on potatoes and milk or cream tend to degrade in the freezer.
When frozen and thawed, the potatoes will become mealy and waterlogged, while the luxurious dairy sauce will separate and curdle.
This recipe is best enjoyed fresh from the oven or from the refrigerator within a few days of your initial baking session.
Common Mistakes to Avoid
One of the most frequent errors home cooks make is using cold milk and cream when building the sauce, which drastically increases the time it takes to thicken.
Removing the aluminum foil too early during the baking process will cause the top layer of cheese to burn long before the potatoes are actually cooked through.
Washing the potato slices in water after you cut them removes the natural starches that are absolutely critical for thickening the bubbly sauce as it bakes.

Frequently Asked Questions
Can I use half-and-half instead of heavy cream? Yes, you can use half-and-half to reduce the calories, but the resulting sauce will be noticeably thinner and slightly less indulgent than the original version.
Why are my potatoes still hard after baking? Hard potatoes are usually the result of slicing them too thickly or an oven that runs colder than the dial indicates. Always check for tenderness with a fork before adding the final cheese layer.
Can I make this in a slow cooker? Yes, you can layer the ingredients in a slow cooker and cook on high for 4 to 5 hours, but you will miss out on the beautiful, crispy, caramelized top crust.
