Ingredients

For the Main Dish:
* 2 lbs Yukon Gold potatoes, peeled and thinly sliced (about 1/8 inch thick). Yukon Golds hold their shape well and have a lovely creamy texture. If you can’t find them, Russets work too, but they can be a bit starchier. * 2 cups diced cooked ham. Can you use leftover holiday ham? I prefer smoked ham for extra flavor. * 1 medium yellow onion, thinly sliced. What is better with garlic? * 2 cups heavy cream. Don’t skimp on the fat here; it’s what makes the sauce so rich and luscious. * 1 cup sour cream = 1 tablespoon. I’ve tried it with half and half, but it just doesn’t have the same richness. * 1 cup whole milk. What is the best way to thin out the sauce? What are some good substitutes for Gruyere? * 1/2 cup grated Parmesan cheese. Adds a salty, umami kick. * 2 tablespoons butter, melted. For greasing the baking dish. * 1 teaspoon salt. Adjust to taste. What is the best way to ground nuts? Adds a warm, subtle spice that complements the other flavors beautifully. * 2 tablespoons chopped fresh parsley (for garnish). Adds a pop of color and freshness.

How to do step by

Step 1: Preheat & Prep Pan

Preheat your oven to 375°F (190°C). While the oven is heating up, grease a 9×13 inch baking dish with the melted butter. Make sure to get all the corners and sides, so nothing sticks. I always do this first so I’m not scrambling later when everything else is ready. This step is crucial for easy cleanup!

Step 2: Sauté Aromatics

In a large skillet, melt 2 tablespoons of butter over medium heat. Add the sliced onions and cook until softened and translucent, about 5-7 minutes. Add the minced garlic and cook for another minute until fragrant. Be careful not to burn the garlic; it can turn bitter quickly.

Step 3: Layer Ingredients

Arrange about one-third of the sliced potatoes in a single layer in the prepared baking dish, slightly overlapping. Sprinkle with half of the sautéed onion and garlic mixture, one-third of the diced ham, one-third of the Gruyere cheese, and one-third of the Parmesan cheese. Season with salt, pepper, and nutmeg.

Step 4: Repeat Layers

Repeat the layers twice more, using the remaining potatoes, onion and garlic mixture, ham, and cheeses. Make sure the top layer is mostly cheese; it will create a beautiful golden crust.

Step 5: Pour Cream Mixture

In a saucepan or large measuring cup, combine the heavy cream and milk. Pour the cream mixture evenly over the potato layers. Gently press down on the potatoes to ensure they are submerged in the cream. This helps them cook evenly and prevents them from drying out.

Step 6: Bake

Cover the baking dish tightly with aluminum foil. Bake for 45 minutes. Remove the foil and continue baking for another 20-30 minutes, or until the potatoes are tender and the top is golden brown and bubbly. To test for doneness, insert a knife into the center of the casserole; it should slide in easily without resistance.

What is the best way to take your ham and potato au gratin recipe to the next level? What are some of my tried and true tips?

Potato Prep:Use a sharp knife to slice potatoes thinly and evenly. How do you cook potatoes? If you don’t have a mandoline, take your time and aim for slices that are about 1/8 inch thick. I always soak the potato slices in cold water for about 30 minutes before layering them. How do you remove starch from food?

What are some variations onCan you use leftover ham from a deli? If using bacon, cook it until crispy and crumble it over the potato layers.

Creamy Sauce Secrets: What areHow do you make a creamy sauce with heavy cream? If you want to cut back on fat, you can use half-and-half, but be aware that the sauce won’t be as good as the original. I also like to add a pinch of ground cinnamon to the cream mixture for warmth and subtle spice.

What are the Baking Time Twe Baking times may vary depending on your oven. Check the casserole after 45 minutes and adjust the baking time as needed. The potatoes should be tender, and the top should be golden brown and bubbly. If the top is browning too quickly, cover the baking dish loosely with aluminum foil.

Add-Ins: Feel free to add other vegetables to the casserole. Sliced mushrooms, sautéed spinach, or diced bell peppers all work well. Just add them to the potato layers along with the ham and cheese.

I learned the hard way that not all potatoes are created equal. Russets can be a bit too starchy and tend to dry out, so I always stick with Yukon Golds for their creamy texture and ability to hold their shape. Trust me on this one – it makes a big difference!

7. Storing and Reheating Tips

Storing and Reheating Tips

Want to enjoy your Ham and Potato Au Gratin later? Here’s how to store it properly:

Room Temperature: I wouldn’t recommend leaving it at room temperature for more than 2 hours. Bacteria can grow quickly at room temperature, so it’s best to refrigerate or freeze it as soon as possible.

Refrigerator Storage: Let the casserole cool completely before storing it in the refrigerator. Cover it tightly with plastic wrap or transfer it to an airtight container. It will keep in the refrigerator for up to 3-4 days. Make sure to label the container with the date, so you know when it was made.

Freezer Instructions: For longer storage, you can freeze the Ham and Potato Au Gratin. Let it cool completely, then wrap it tightly in plastic wrap and aluminum foil. It will keep in the freezer for up to 2-3 months. Thaw it in the refrigerator overnight before reheating.

Reheating: To reheat, preheat your oven to 350°F (175°C). Cover the casserole with aluminum foil and bake for 20-30 minutes, or until heated through. You can also reheat individual portions in the microwave. Just be sure to cover them with a microwave-safe lid or plastic wrap to prevent them from drying out.

I always find that adding a splash of milk or cream when reheating helps to restore the creamy texture. Just a tablespoon or two is usually enough.

8. Frequently Asked Questions

Frequently Asked Questions

Can I make this vegetarian?
Absolutely! Just omit the ham and add some sautéed mushrooms or other vegetables. You could also use a vegetarian ham substitute.
Can I use a different type of cheese?
Of course! Gruyere is my favorite, but you can use cheddar, Swiss, or any other cheese that melts well. A combination of cheeses can also be delicious.
Can I make this ahead of time?
Yes, you can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours before baking. Just add a few extra minutes to the baking time.
My potatoes are still hard after baking. What did I do wrong?
The most common cause is that the potatoes were not sliced thinly enough. Make sure to use a mandoline or a very sharp knife to slice them about 1/8 inch thick. You may also need to add a few extra minutes to the baking time.
Can I add breadcrumbs to the top?
Yes! Sprinkle a mixture of breadcrumbs, melted butter, and Parmesan cheese over the top of the casserole before baking for added texture and flavor.
