Ingredients Notes
The quality of your ingredients can make a massive difference in the overall flavor. Opt for a sharp cheddar cheese to add a more robust flavor profile. For the potatoes, look for firm and blemish-free options. Yukon Golds are a great choice, boasting a buttery texture. Finally, ensure your ham is fully cooked and free from excessive fat.
Recipe Steps
Step 1
Preheat your oven to 375°F (190°C). While the oven heats, peel and thinly slice the potatoes into even rounds, about 1/8 inch thick.
Step 2
In a large pan over medium heat, melt butter and sauté onion until it turns translucent. Gradually add flour, creating a thick paste. Slowly whisk in milk, stirring continuously until the sauce thickens.
Step 3
Layer half of the sliced potatoes in a greased baking dish. Scatter diced ham on top, followed by a layer of shredded cheese. Pour over half of the sauce, spreading evenly.
Step 4
Repeat the layers using the remaining potatoes, ham, cheese, and sauce. Cover the dish with aluminum foil and bake for 45 minutes.
Step 5
Remove the foil and bake for an additional 15 minutes, or until the potatoes are tender and the top is golden brown. Let it cool for a few minutes before serving.
Storage Options
Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. To freeze, wrap individual portions in plastic wrap, then place them in a freezer bag for up to 2 months. Reheat in the oven at 350°F (175°C) for about 20 minutes, or until heated through.
Variations & Substitutions
For a vegetarian option, substitute the ham with sautéed mushrooms or blanched broccoli. If you’re lactose intolerant, use a non-dairy milk alternative and vegan cheese shreds. To add a spicy twist, incorporate diced jalapeños or a pinch of cayenne pepper.
Serving Suggestions
This casserole pairs beautifully with a crisp green salad and a side of garlic bread for a complete meal. It’s also a hit at potlucks and is best served hot from the oven to highlight its cheesy goodness.
Frequently Asked Questions
Can I make this casserole ahead of time? Yes, you can assemble the casserole a day in advance and refrigerate it until you’re ready to bake. Just add 5–10 more minutes to the baking time if baking straight from the fridge.
What’s the best way to slice the potatoes? For uniform cooking, thin slices of about 1/8 inch are ideal. A mandoline slicer can be helpful for achieving even slices quickly and safely.
Is it possible to use sweet potatoes instead of regular potatoes? Absolutely! Sweet potatoes add a naturally sweet flavor that contrasts nicely with the savory elements of the ham and cheese.
