Ingredients for Cheesy Ham Potato Casserole

This recipe uses simple, flavorful ingredients that come together beautifully. Here’s what you’ll need:

 

 

 

 

Core Ingredients

• 2 pounds potatoes, peeled and thinly sliced (about 4–5 medium potatoes)
• 2 cups diced cooked ham
• 1 can (10.5 oz) cream of mushroom soup
• 1 cup sour cream
• ½ cup milk
• 2 cups shredded sharp cheddar cheese (divided)
• ½ cup grated Parmesan cheese
• 1 teaspoon garlic powder
• ½ teaspoon onion powder
• ½ teaspoon salt
• ¼ teaspoon black pepper
• 2 tablespoons melted butter
• Fresh parsley for garnish

Ingredient Notes and Substitutions

Potatoes: Russet or Yukon Gold potatoes work best. Russets are starchier and creamier, while Yukon Golds hold their shape slightly better.

 

 

 

 

Ham: Diced cooked ham adds a smoky, salty flavor. You can also use leftover holiday ham, bacon, or cooked sausage.

 

 

 

 

Soup: Cream of mushroom is classic, but you can also use cream of chicken or cream of celery.

 

 

 

 

Sour Cream: Adds tanginess and creaminess. You can substitute with plain Greek yogurt.

 

 

 

 

Cheese: Sharp cheddar gives the best flavor. You can also use a blend of cheddar and Monterey Jack.

 

 

 

 

Step‑by‑Step Instructions

Follow these simple steps to create a perfect Cheesy Ham Potato Casserole every single time.

 

 

 

 

1. Preheat and Prepare

Preheat your oven to 375°F (190°C). Grease a 9×13‑inch baking dish with butter or non‑stick spray.

 

 

 

 

2. Slice the Potatoes

Peel the potatoes and slice them into ¼‑inch thick rounds. You can use a mandoline for even slices.

 

 

 

 

3. Make the Creamy Sauce

In a large bowl, combine the cream of mushroom soup, sour cream, milk, garlic powder, onion powder, salt, and pepper. Whisk until smooth. Stir in 1½ cups of the shredded cheddar cheese.

 

 

 

 

4. Assemble the Casserole

Layer half of the sliced potatoes in the bottom of the prepared dish. Top with half of the diced ham and half of the cheese sauce. Repeat the layers, ending with the remaining sauce on top.

 

 

 

 

5. Top with Cheese

Sprinkle the remaining ½ cup of cheddar cheese and the Parmesan cheese over the top. Drizzle with the melted butter.

 

 

 

 

6. Bake

Cover the dish with foil and bake for 45 minutes. Remove the foil and bake for an additional 15–20 minutes, until the potatoes are tender and the top is golden and bubbly. If the top is browning too quickly, cover loosely with foil.

 

 

 

 

7. Rest and Serve

Let the casserole rest for 5–10 minutes before serving. Garnish with fresh parsley and serve.

 

 

 

 

Expert Tips for the Perfect Casserole

This recipe is simple, but a few expert tricks will elevate it to perfection. Here’s what I’ve learned from making this casserole countless times:

 

 

 

 

• Slice potatoes evenly – even slices ensure the potatoes cook evenly.
• Use full‑fat sour cream – it gives the richest, creamiest texture.
• Don’t overmix – gently fold the ingredients together to keep the potatoes from breaking apart.
• Cover while baking – covering the casserole for the first 45 minutes traps steam and ensures the potatoes cook through.
• Make it ahead – assemble the casserole (without baking) up to 24 hours in advance. Refrigerate and bake when ready.
• Add extra vegetables – try adding sautéed onions, mushrooms, or broccoli.
• Use a different meat – swap the ham for cooked bacon, sausage, or even shredded chicken.
• Freeze for later – this casserole freezes beautifully. Assemble, cover tightly, and freeze for up to 2 months.

Delicious Variations

One of the best things about this recipe is how easily it adapts to different tastes and cravings. Here are some of my favorite ways to switch it up:

 

 

 

 

Bacon and Potato Casserole

Swap the ham for ½ pound of crispy cooked bacon, crumbled. The bacon adds a smoky, savory flavor.

 

 

 

 

Sausage and Potato Casserole

Use cooked breakfast sausage and add sautéed bell peppers and onions. The sausage and peppers add a hearty, flavorful twist.

 

 

 

 

Broccoli Cheese Potato Casserole

Add 2 cups of steamed broccoli florets to the layers. The broccoli adds color and nutrition.

 

 

 

 

Southwest Potato Casserole

Add 1 can of diced green chilies and 1 teaspoon of cumin. Top with pepper jack cheese for a spicy kick.

 

 

 

 

Gluten‑Free Potato Casserole

Use a gluten‑free cream soup for a gluten‑free version.

 

 

 

 

Dairy‑Free Potato Casserole

Use dairy‑free cream soup, dairy‑free sour cream, and dairy‑free cheese.

 

 

 

 

Serving Suggestions

This versatile casserole can be served in a variety of ways, making it perfect for any occasion:

 

 

 

 

• As a main dish – serve with a side salad or steamed vegetables.
• As a side dish – pair with roasted chicken, steak, or pork chops.
• For holidays – a must‑have for Easter, Christmas, or Thanksgiving.
• For potlucks – easy to transport and always a hit.
• With a dollop of sour cream – adds a cool, tangy contrast.
• With fresh herbs – parsley or chives add a bright, fresh finish.
• With crusty bread – perfect for soaking up any extra sauce.

Storage and Reheating Guidelines

This casserole stores beautifully, making it a fantastic make‑ahead option.

 

 

 

 

Refrigeration: Store in an airtight container in the refrigerator for up to 4 days. The flavors deepen and intensify overnight.

 

 

 

 

Reheating: For the best texture, reheat in a 350°F oven for 15–20 minutes until warmed through. You can also microwave individual portions for 2–3 minutes.

 

 

 

 

Freezing: This casserole freezes beautifully. Place it in a freezer‑safe container, leaving a little headspace, and freeze for up to 2 months. Thaw overnight in the refrigerator and reheat in the oven.

 

 

 

 

Pro tip: If the top loses its crispiness upon reheating, sprinkle a little extra cheese on top before warming.
