How to Make Scalloped Potatoes and Ham Casserole Recipe

Step 1: Prepare Your Oven and Dish

Start by preheating your oven to 375°F (190°C) and greasing a 9×13-inch baking dish thoroughly. This ensures your casserole won’t stick and helps create that beautiful golden crust on the top layer.

Step 2: Sauté the Onions and Create the Roux

Next, melt butter in a medium saucepan over medium heat. Toss in the finely diced onions and sauté for about 3 to 4 minutes until they become soft and fragrant. Then, sprinkle the flour evenly and cook it with the onions for 1 minute, stirring constantly to form a roux that will thicken your sauce without lumps.

Step 3: Whisk in the Milk and Seasonings

Slowly add the milk to the roux while whisking continuously to keep the sauce silky. Stir in the garlic powder, salt, and black pepper. Let the mixture simmer gently until it thickens to a creamy, dreamy consistency that clings perfectly to the potatoes and ham.

Step 4: Add Cheese to the Sauce

Once the sauce has thickened, remove it from the heat and stir in half of your shredded cheddar cheese. This melts right into the sauce, amplifying the comfort and cheesiness that makes this Scalloped Potatoes and Ham Casserole Recipe so irresistible.

Step 5: Layer Your Ingredients

Time to assemble the magic in your baking dish. Start with a layer of half the sliced potatoes, spread evenly, then scatter half the diced ham on top. Pour half the cheese sauce over this layer so everything gets nicely coated. Repeat these layers with the remaining potatoes, ham, and sauce.

Step 6: Finish with Cheese and Bake

Sprinkle the remaining cheddar cheese evenly over the top. Cover the dish tightly with foil and bake for 40 minutes. Then, remove the foil and continue baking for another 20 to 25 minutes to allow the top to brown beautifully and for the potatoes to become tender all the way through.

Step 7: Let It Rest Before Serving

Once out of the oven, give the casserole at least 10 minutes to rest. This pause lets everything set, makes serving easier, and heightens all those melded flavors. Garnish with a sprinkle of fresh parsley for a cheerful finishing touch if you like.

Garnishes

Fresh parsley is a classic garnish that adds a lovely visual pop and a hint of freshness cutting through the rich flavors. You can also try a little snip of chives or a light dusting of smoked paprika for some color and subtle smokiness.

Side Dishes

This hearty casserole pairs wonderfully with a crisp green salad tossed in a tangy vinaigrette or some steamed green beans for balance. Roasted vegetables like asparagus or Brussels sprouts are also fantastic complements that bring texture and nutrition to the plate.

Creative Ways to Present

For a crowd, bake your scalloped potatoes and ham in smaller ramekins to create individual servings that look elegant and inviting. Alternatively, serve it buffet-style so everyone can help themselves to their preferred portion. It also makes a great potluck dish that’s sure to disappear quickly!

Make Ahead and Storage

Storing Leftovers

Store leftovers in an airtight container in the refrigerator for up to 3 days. The flavors deepen overnight, making the next-day meal just as satisfying.

Freezing

This casserole freezes beautifully. Assemble the dish, cover tightly with foil and plastic wrap, and freeze for up to 2 months. When ready to enjoy, thaw overnight in the fridge before baking as directed.

Reheating

Reheat leftovers covered in the oven at 350°F (175°C) for about 20 minutes or until warmed through. To revive the crisp top, remove the cover during the last 5 minutes. Microwaving works in a pinch but may sacrifice the lovely texture.

FAQs

Can I use a different type of cheese?

Absolutely! While cheddar is traditional for its sharp, melty qualities, feel free to experiment with mozzarella for stretchiness, Gruyère for nuttiness, or even a blend that suits your taste. Just keep the cheese quantity similar to maintain the creamy texture.

Is there a gluten-free option for this recipe?

Yes! Simply substitute the all-purpose flour with a gluten-free flour blend that measures like regular flour. This swap allows you to enjoy the casserole without worrying about gluten.

Can I add vegetables to the casserole?

Definitely. Peas, chopped broccoli, or fresh spinach are excellent vegetables to mix in layers or stir into the sauce. They add color, nutrition, and extra flavor to your casserole.

What’s the best potato to use?

Russet or Yukon gold potatoes both work wonderfully. Russets give a fluffier, more absorbent texture, while Yukon golds provide a buttery creaminess. Either way, slicing them thinly ensures they cook perfectly in the baking dish.

How can I get a crispy top on the casserole?

For a delightfully crispy and golden top, after baking, switch your oven to broil and broil the casserole uncovered for 1–2 minutes. Keep a close eye to prevent burning and enjoy that irresistible crunch.
