Easy Ham and Potato Casserole with Cheddar Cheese Soup

December 2, 2025

This easy ham and potato casserole with cheese soup delivers creamy, cheesy comfort in just 90 minutes with minimal prep and very basic ingredients. The secret is Campbell's condensed cheddar cheese soup whisked with milk, creating a velvety sauce that transforms everyday ingredients into a hearty family meal. The combination of tender potato layers, savory ham chunks, and that rich cheese sauce never disappoints! 

The smell of this casserole - that warm, buttery scent mingling with sharp cheddar and a hint of green onion - transforms a hectic Tuesday into something comforting. The gentle sizzle as the edges bubble golden brown, the way steam rises when you first cut into it. This is the kind of dish that saves busy weeknights when everyone's starving and you need dinner on the table fast, yet it's impressive enough for church potlucks and game day gatherings where you need to feed a crowd without spending all day in the kitchen.

The 1980s Kitchen

The 1980s marked a golden era for convenience cooking, when Campbell's soup transformed from a simple starter into a culinary building block. Kitchens featured almond-colored appliances, AM/FM radios playing Top 40 hits, and cupboards stocked with condensed soups that promised "creative cooking" without culinary school training. This was the Reagan years, when dual-income households became the norm and weeknight dinners needed to be both budget-friendly and fast.

Campbell's marketed their condensed cheddar cheese soup as an instant cheese sauce, eliminating the intimidation of making a roux or tempering a béchamel. For home cooks juggling careers and families, these canned shortcuts weren't lazy; they were liberating!

The company even published dedicated cookbooks in the 80s showcasing "creative cooking with soup," teaching a generation that sophisticated flavor could come from a can. Ham and potato casseroles gained particular traction as the perfect vessel for leftover holiday ham, transforming Easter and Christmas remnants into economical weeknight meals that fed a family of six for under $5.

What Makes This Ham Potato Casserole Special

  • Campbell's Cheese Soup Creates Foolproof Sauce
    The condensed cheddar cheese soup eliminates the risk of grainy or separated cheese sauce that plagues scratch-made versions. When whisked with milk, the soup's emulsifiers keep the fat and protein molecules bonded, delivering consistent creaminess every time. The sodium and acids in the soup also act as melting salts, ensuring smooth texture even when reheated - a game-changer for make-ahead meals or next-day leftovers.
  • Grated Potato Topping Adds Textural Contrast
    While most ham casseroles feature uniform potato slices, this recipe's secret weapon is the grated potato layer on top. As it bakes, these fine shreds crisp at the edges while the starches underneath thicken the sauce naturally. The result is a casserole with multiple textures: tender potato slices at the base, creamy sauce in the middle, and those delightfully crispy potato strands catching the breadcrumb topping.
  • Green Onions Provide Fresh Brightness
    The chopped green onions sprinkled before baking add a mild, sweet onion flavor that cuts through the richness without overpowering the dish. Unlike yellow onions, which can turn acrid when overcooked, green onions mellow and sweeten during the long bake time. Their fresh, grassy notes balance the heavy dairy and salty ham, making each bite feel lighter than it actually is.
  • The 9x13 Pan Size Maximizes Surface Area
    Using a 9x13-inch casserole pan creates the ideal ratio of crispy edges to creamy center. This specific size allows the cheese sauce to distribute evenly without pooling, and provides enough surface area for that coveted golden-brown breadcrumb crust. Deeper pans would steam the middle and prevent proper browning, while shallower pans would overcook the potatoes before the sauce thickens.

  • Total Time: 1 hour 50 minutes
  • Yield: 8 servings 1x

Ingredients

Units Scale
  • 6-8 medium russet potatoes (about 2 1/2-3 lbs), sliced thin or cubed
  • 2 cups grated russet potatoes (about 2 medium potatoes)
  • 1 tablespoon ground black pepper
  • 1-2 lbs cooked ham, cubed (about 3-4 cups)
  • 1 cup whole milk
  • 2 cans (10.5 oz each) Campbell's Condensed Cheddar Cheese Soup
  • 1 bunch green onions, chopped (about 1/2 cup)
  • 1 cup bread crumbs (optional but recommended)
  • 1/4 cup fresh parsley, chopped (for garnish)

Instructions

  1. Preheat and Prep: Preheat oven to 350°F. Grease a 9×13-inch casserole dish with butter or cooking spray.
  2. Layer the Base: Arrange sliced or cubed potatoes in an even layer on the bottom of the prepared casserole dish. Scatter the cubed ham over the potatoes. Season with the full tablespoon of black pepper. Spread the grated potatoes evenly over the top.
  3. Make the Cheese Sauce: In a medium bowl, whisk together the milk and both cans of Campbell’s Cheddar Cheese Soup until completely smooth with no lumps. Pour this mixture evenly over the layered potatoes and ham.
  4. Add Toppings: Sprinkle the chopped green onions over the cheese sauce. If using, sprinkle bread crumbs evenly across the top.
  5. Bake Covered: Cover the casserole dish tightly with aluminum foil. Bake in the preheated oven for 60 minutes.
  6. Finish Uncovered: Remove foil and continue baking for 30-45 minutes more, until potatoes are fork-tender and the top is golden brown. Baking time depends on potato variety and slice thickness.
    Rest and Serve: Remove from oven and let rest for 10-15 minutes. Sprinkle with freshly chopped parsley just before serving.

How to Make Perfect Ham Potato Casserole

  • Choose Russet or Yukon Gold Potatoes
    I've tried this recipe with waxy red potatoes and starchy russets, and russets win, hands down. Their high starch content absorbs the cheese sauce beautifully while breaking down just enough to thicken the liquid. Yukon Golds work well too, offering a buttery flavor and creamy texture. Avoid red or new potatoes; they stay too firm and create a watery casserole since they don't release enough starch to bind the sauce.
  • Slice Potatoes Uniformly Thin
    Aim for ⅛-inch slices to ensure even cooking throughout the 90-minute bake time. I use a mandoline for consistent thickness, but a sharp knife and patience work just as well. Uneven slices mean some pieces turn mushy while others stay crunchy, which isn't the texture we're after. If you prefer cubes instead of slices, keep them to ½-inch maximum so they soften completely.
  • Don't Skip the Black Pepper
    One full tablespoon of black pepper might seem excessive, but it's essential for cutting the richness. The piperine in black pepper stimulates taste receptors that balance fatty, creamy foods. If you reduce it to one teaspoon, the casserole will taste flat and one-dimensional. Use freshly ground pepper for the most aromatic punch.
  • Whisk the Soup and Milk Thoroughly
    Take an extra minute to whisk the Campbell's cheese soup and milk until completely smooth with no lumps. This ensures even distribution of the cheese and prevents pockets of concentrated soup flavor. The mixture should look like thin gravy; pourable but not watery. If it seems too thick, add milk by the tablespoon; too thin, and your casserole will be soupy rather than saucy.
  • Cover for the First Hour, Then Uncover
    Starting covered traps steam, which helps the potatoes cook through without drying out the edges. After an hour, remove the foil to allow the top to brown and the sauce to thicken. If you bake uncovered the entire time, you'll end up with burnt breadcrumbs and raw potatoes in the center. Check doneness by inserting a knife through the middle. It should slide through easily with no resistance.
  • Let It Rest Before Serving
    After removing from the oven, let the casserole rest for 10-15 minutes before cutting. This resting period allows the sauce to set and thicken, preventing a runny mess when you serve. The residual heat continues cooking gently, and the starches from the potatoes complete their thickening action. Sprinkle fresh parsley just before serving for a pop of color and fresh herb flavor.

Recipe Variations

  • For a lighter version, substitute reduced-fat Campbell's cheese soup and use low-fat milk, though the sauce will be slightly thinner.
  • Add diced bell peppers or broccoli florets between the potato layers for extra vegetables; just reduce ham to 1 pound to maintain proper ratios. 
  • Turkey lovers can swap the ham entirely for leftover roasted turkey after Thanksgiving.
  • For a spicier kick, add ½ teaspoon cayenne pepper to the cheese sauce or use pepper jack cheese in place of the condensed cheddar soup.

Frequently Asked Questions

Can I use fresh potatoes or do I need frozen hash browns?

This recipe calls for fresh potatoes (either sliced thin or cubed) not frozen hash browns. Fresh russet or Yukon Gold potatoes provide the right starch content to thicken the cheese sauce naturally. If you prefer using hash browns, use the shredded variety and thaw completely before layering

What can I substitute for Campbell's Cheddar Cheese Soup?

You can make a homemade cheese sauce by melting 2 cups shredded cheddar into a roux made with 3 tablespoons butter, 3 tablespoons flour, and 2 cups milk. However, the condensed soup provides emulsifiers that prevent separation, so homemade versions may be slightly grainier. Cream of chicken or cream of mushroom soup can substitute in a pinch, though you'll lose the prominent cheese flavor.

How do I know when the casserole is done?

Insert a knife or fork through the center of the casserole; it should slide through the potatoes with no resistance. The edges should be bubbling, the top golden brown, and the sauce thickened rather than watery. Baking time varies from 90 minutes to 2 hours, depending on potato type and slice thickness.

Why is my casserole watery?

Watery casseroles typically result from potatoes that are too thick, not enough baking time for the sauce to reduce, or using waxy potatoes that don't release starch. Always use starchy russets, slice uniformly thin, and don't skip the uncovered baking time. Let the casserole rest 10-15 minutes after baking so the sauce can set.

Can I add other vegetables to this casserole?

Absolutely! Diced bell peppers, broccoli florets, or peas work beautifully. Add them to the potato layer before pouring the cheese sauce. Keep additions to 1-2 cups maximum so the casserole doesn't become overcrowded and watery. Pre-cook harder vegetables like broccoli for 2-3 minutes before adding.

What type of ham works best?

Leftover holiday ham (spiral-cut glazed ham), ham steak from the deli counter, or even thick-cut deli ham all work perfectly. Avoid honey-glazed ham if you don't want sweetness competing with the savory cheese sauce. Smoked ham adds wonderful depth, while plain deli ham keeps the flavor mild and kid-friendly.

Can I use a different size baking dish?

The 9x13-inch pan is ideal for proper sauce-to-potato ratio and even cooking. A deeper 2.5-quart casserole dish works but requires 15-20 minutes longer baking time and produces fewer crispy edges. Two smaller 8x8-inch pans allow you to freeze one for later, just reduce baking time to 60-75 minutes total.

Do I have to use breadcrumbs on top?

The breadcrumbs are optional but highly recommended for textural contrast. They create a golden, slightly crunchy topping that balances the creamy interior. For extra richness, toss the breadcrumbs with 2 tablespoons melted butter before sprinkling. Crushed butter crackers (like Ritz) or panko also works nicely.

How do I prevent the cheese sauce from curdling?

Campbell's condensed cheese soup is formulated with emulsifiers to prevent curdling, which is why this recipe is so foolproof. If making homemade cheese sauce instead, remove from heat before adding cheese, and stir constantly as it melts. Never boil cheese sauce, as high heat causes proteins to seize and separate.

Does this bring back memories of family dinners where one casserole dish fed everyone? What's your favorite way to use leftover ham? Traditional casseroles like this, or do you get creative?
