Gathering Your Ingredients

Before we begin, let's make sure you have everything you need. This recipe serves 8-10 people and takes about 1 hour and 15 minutes from start to finish.

What You'll Need:

For the Base:

6-8 medium russet potatoes, peeled and diced into 1/2-inch cubes
2 cups cooked ham, diced into small cubes
1 medium onion, finely chopped
3 cloves garlic, minced
1/2 cup butter, melted
1 can (10.75 oz) cream of chicken or cream of mushroom soup
1 cup sour cream
1/2 cup milk
Salt and black pepper to taste
1/2 teaspoon paprika

For the Topping:

2 cups shredded cheddar cheese (or a mix of cheddar and mozzarella)
1 cup shredded Colby Jack or Monterey Jack cheese
1/2 cup green onions, sliced (for garnish)
Optional: 1/2 cup crushed Ritz crackers or breadcrumbs mixed with 2 tbsp melted butter for extra crunch

Equipment Needed:

9x13 inch baking dish
Large pot for boiling potatoes
Mixing bowls
Colander
Aluminum foil

Step-by-Step Instructions

Step 1: Prepare the Potatoes

Start by preheating your oven to 350°F (175°C). Grease your 9x13 inch baking dish with cooking spray or butter and set aside.

Place the diced potatoes in a large pot and cover with cold water by about 2 inches. Add a generous pinch of salt to the water. Bring to a boil over high heat, then reduce to medium and cook for 8-10 minutes, or until the potatoes are just tender but still hold their shape. You want them fork-tender but not mushy, as they'll continue cooking in the oven.

Drain the potatoes well in a colander and set aside. This par-cooking step is crucial—it ensures the potatoes are perfectly tender in the finished casserole without becoming mushy.

Step 2: Create the Creamy Base

In a large mixing bowl, combine the melted butter, cream of chicken soup, sour cream, and milk. Whisk until smooth and well blended. This creates the rich, creamy sauce that binds everything together.

Add the minced garlic, chopped onion, paprika, salt, and pepper to the mixture. Stir well to distribute the flavors evenly throughout the sauce.

Step 3: Combine Everything

Gently fold the par-cooked potatoes and diced ham into the creamy sauce mixture. Be gentle to avoid breaking up the potato pieces too much. You want everything evenly coated in that luscious sauce.

Taste and adjust seasoning if needed. Remember, the ham and cheese will add saltiness, so don't over-salt at this stage.

Step 4: Assemble the Casserole

Transfer the potato and ham mixture into your prepared baking dish, spreading it out evenly. Use a spatula to smooth the top.

In a medium bowl, combine the shredded cheddar and Colby Jack cheeses. Sprinkle the cheese mixture evenly over the top of the casserole, making sure to cover the entire surface. This will create that beautiful, bubbly, golden-brown crust you see in the photo.

Pro Tip: For extra crunch and texture, you can mix crushed crackers or breadcrumbs with melted butter and sprinkle them over the cheese before baking.

Step 5: Bake to Perfection

Cover the dish loosely with aluminum foil (this prevents the cheese from browning too quickly). Bake for 30 minutes.

After 30 minutes, remove the foil and continue baking for another 15-20 minutes, or until the cheese is melted, bubbly, and starting to turn golden brown around the edges. The casserole should be heated through and bubbling around the edges.

If you want extra browning on top, you can broil for the last 2-3 minutes, but watch it carefully—cheese can go from golden to burnt quickly!

Step 6: Rest and Garnish

Remove the casserole from the oven and let it rest for 10-15 minutes before serving. This resting time allows the casserole to set, making it easier to cut and serve neat portions.

Just before serving, sprinkle the sliced green onions over the top for a fresh, colorful garnish that adds a nice pop of color and a hint of onion flavor.

Serving Suggestions and Variations

What to Serve With This Casserole

This hearty casserole is a complete meal in itself, but it pairs beautifully with:

A crisp green salad with vinaigrette dressing
Steamed or roasted vegetables (broccoli, green beans, or asparagus)
Crusty bread or dinner rolls
Coleslaw for a crunchy contrast

Delicious Variations to Try

Broccoli Cheddar Version

Add 2 cups of steamed broccoli florets along with the ham for a veggie-packed version that's equally delicious.

Bacon Lover's Dream

Swap the ham for crispy bacon bits, or use a combination of both for the ultimate meaty experience.

Vegetarian Option

Omit the ham and add sautéed mushrooms, bell peppers, and spinach for a meatless version that's still satisfying.

Tex-Mex Twist

Add diced green chiles, use pepper jack cheese, and top with salsa and sour cream for a Southwestern flair.

Chicken Version

Use cooked, diced chicken instead of ham for a different protein option that's equally tasty.

Storage and Reheating Tips

Storing Leftovers

This casserole keeps beautifully in the refrigerator for up to 4 days. Store in an airtight container or cover the baking dish tightly with plastic wrap or aluminum foil.

Freezing

You can freeze this casserole either before or after baking:

Unbaked: Assemble the casserole (without baking), wrap tightly in plastic wrap and then foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before baking as directed.
Baked: Let the baked casserole cool completely, wrap tightly, and freeze for up to 2 months. Thaw in the refrigerator and reheat in a 350°F oven until warmed through.

Reheating

For individual portions, microwave for 2-3 minutes until heated through. For larger portions or the whole casserole, cover with foil and reheat in a 350°F oven for 20-30 minutes, or until bubbly.

Make-Ahead Instructions

This casserole is perfect for meal prep and entertaining because you can prepare it in advance:

Assemble the casserole completely (through Step 4) up to 24 hours before baking
Cover tightly and refrigerate
When ready to bake, remove from refrigerator and let sit at room temperature for 20-30 minutes
Bake as directed, adding an extra 5-10 minutes to the covered baking time since it's starting from cold

Tips for Success

Don't overcook the potatoes initially - They should be just tender, as they'll continue cooking in the oven
Use freshly shredded cheese - Pre-shredded cheese contains anti-caking agents that can affect melting
Let it rest before serving - This prevents a soupy texture and makes serving easier
Don't skip the resting time - It's tempting to dig in immediately, but patience pays off!
Adjust cheese to your preference - Love cheese? Add more! Want less? Reduce accordingly
