This Cheesy Ham and Potato Casserole is a comforting dish that comes together quickly and can be prepared ahead of time. Tender potatoes and savory ham are enveloped in a creamy cheese sauce, making it perfect for family dinners or holiday leftovers. The melted cheddar cheese on top adds that irresistible gooey finish everyone loves.
Ingredients
- Little potatoes: such as Boomer Gold from The Little Potato Company make prep effortless because they come fully cleaned and ready to quarter.
- Salted butter: adds rich flavor I usually stick with salted but unsalted can work if you adjust the seasoning.
- Finely diced onion: provides a subtle sweetness and texture that blends nicely into the sauce.
- Minced garlic: brings warmth and depth - fresh is best but pre-minced from a jar works in a pinch.
- Dried parsley, salt, black pepper, and paprika: create a simple seasoning mix that enhances the casserole without overpowering it.
- All-purpose flour: is the thickening agent for a silky cheese sauce.
- Half-and-half or whole milk: adds creaminess half-and-half gives a richer result but whole milk does just fine.
- Sour cream: adds tang and helps thicken the sauce for a luscious mouthfeel.
- Cubed cooked ham: provides protein and a savory punch, perfect for using up leftovers.
- Shredded cheddar cheese: tops the casserole, melting into delicious gooeyness that seals in all the flavors.
Step-by-Step Instructions
- Prep the Potatoes:
- Quarter the potatoes and place them in a large pot. Cover with cold water, season with a little salt, and bring to a boil over high heat. Reduce heat to medium-high and cook until the potatoes are just tender, about 10 minutes. Drain and set aside.
- Make the Cream Sauce:
- Melt the butter in a large skillet over medium heat. Add the finely diced onion and cook until it becomes soft and translucent, which usually takes about 5 minutes. Stir in the minced garlic along with the dried parsley, salt, black pepper, and paprika. Cook these together for about one minute to bloom the spices and deepen the flavor. Whisk in the all-purpose flour until combined and smooth. Slowly pour in the half-and-half while stirring constantly. Continue to cook and whisk the mixture over medium heat until it thickens to a creamy sauce consistency. Remove from heat and stir in the sour cream, blending it well into the sauce for extra richness and a hint of tang.
- Assemble and Bake:
- Place the cooked potatoes and cubed ham in a lightly greased 9 by 13-inch baking dish. Pour the creamy sauce over the top and gently stir everything together so the potatoes and ham are evenly coated. Sprinkle the shredded cheddar cheese evenly over the casserole. Bake uncovered in a preheated 350 degrees Fahrenheit oven for approximately 20 minutes or until the cheese is melted and bubbling. The top should be golden and inviting.
Storage Tips
Store leftover baked casserole in an airtight container in the fridge for up to three days. Reheat it slowly in the oven at 350 degrees Fahrenheit until warmed through to keep the cheese melty and the potatoes tender. If you plan to freeze it, assemble but do not bake. Wrap tightly and freeze for up to three months. Thaw overnight in the fridge before baking.
Ingredient Substitutions
If you don't have Boomer Gold potatoes, Yukon Gold or red potatoes work great as they hold their shape well after cooking. You can replace sour cream with Greek yogurt for a lighter tang. Try Monterey Jack or Gouda as alternative cheeses for a twist on flavor and meltiness. Ground sausage or cooked turkey can be used instead of ham for a different protein choice.
Serving Suggestions
Serve this casserole at brunch alongside crispy bacon and fresh fruit for a complete meal. As a side dish, it pairs wonderfully with roasted vegetables or a simple green salad to balance its richness. It also works well as a hearty main course, especially on chilly nights, accompanied by warm dinner rolls and steamed broccoli.
Cultural Context
Cheese and potatoes are deeply rooted comfort food staples in American and Canadian kitchens. Adding ham makes this casserole a classic way to use up holiday leftovers or craft a quick family meal on busy nights. This blend of ingredients represents the hearty, satisfying dishes common to Midwestern and Northern American home cooking where warm, filling casseroles are beloved year-round.
Recipe FAQs
- → What type of ham is best to use?
Any cooked, cubed ham works well, whether leftover or store-bought. The key is to use a ham with good flavor and firm texture to complement the potatoes and sauce.
- → Should the casserole be covered while baking?
It’s usually baked uncovered for about 20 minutes to allow the cheese to melt and bubble. If the top browns too quickly, covering loosely with foil can prevent overbrowning.
- → Can this dish be prepared ahead of time?
Yes, assemble the casserole up to baking, cover with plastic wrap, and refrigerate for up to 4 days. Add extra bake time if baking from cold.
- → How do I know when the potatoes are tender?
Boil the quartered potatoes until they can be easily pierced with a fork, usually about 10 minutes, ensuring they remain intact to avoid a mushy texture.
- → What variations can be made for extra flavor?
Consider adding cooked vegetables such as bell peppers or broccoli, swapping cheeses like mozzarella or gouda, or stirring in spices like cayenne or red pepper flakes for a bit of heat.
