What Ingredients You Will Need

This recipe uses simple, everyday ingredients that you likely already have in your kitchen. Here’s what you’ll need:

• Potatoes: 6 medium-sized russet or Yukon Gold potatoes, peeled and thinly sliced (about 1/8-inch thick).
• Cooked ham: 2 cups, diced (use leftover ham for convenience).
• Onion: 1 medium onion, diced (adds a savory depth).
• Shredded cheese: 2 cups (cheddar works best, but you can use a mix like Colby Jack or Gruyère).
• Milk: 2 cups (use whole milk for creaminess, or a dairy-free option if needed).
• Butter: 2 tablespoons, unsalted.
• All-purpose flour: 2 tablespoons (for the roux; use gluten-free flour if preferred).
• Garlic powder: 1 teaspoon.
• Salt and pepper: To taste.
• Fresh parsley: Optional, for garnish.

If you want to add more veggies, you can toss in peas, broccoli florets, or even spinach. For a smoky twist, try adding a dash of smoked paprika or swapping cheddar for smoked gouda. The beauty of this casserole is its flexibility!

Equipment Needed

Here’s the gear you’ll need to make this Ultimate Ham and Potato Casserole:

• Baking dish: A 9×13-inch dish works perfectly.
• Cutting board: For slicing potatoes and chopping ham.
• Sharp knife: A good knife makes prepping the ingredients so much easier.
• Large skillet: To make the creamy sauce.
• Whisk: For a smooth, lump-free sauce.
• Mandoline slicer: Optional, but great for evenly slicing potatoes.

If you don’t have a mandoline slicer, a sharp knife will do the trick—just take your time to make sure the slices are thin and even. For budget-friendly bakers, you can find affordable baking dishes at most home stores or online.

Preparation Method

1. Preheat the oven: Set your oven to 375°F (190°C) and grease a 9×13-inch baking dish lightly with butter or non-stick spray.
2. Prepare the potatoes: Peel and slice the potatoes into thin rounds, about 1/8-inch thick. If you have a mandoline slicer, this step will be a breeze!
3. Cook the sauce: In a large skillet, melt 2 tablespoons of butter over medium heat. Add the flour and whisk until smooth, creating a roux. Gradually pour in the milk while whisking continuously to prevent lumps. Add garlic powder, salt, and pepper to taste. Cook for 3-4 minutes, or until the sauce thickens slightly.
4. Layer the casserole: Spread a thin layer of the sauce on the bottom of the baking dish. Arrange a layer of potato slices, followed by a layer of diced ham and onions. Sprinkle a handful of shredded cheese on top. Repeat the layers until all ingredients are used, finishing with a generous layer of cheese.
5. Bake: Cover the dish with aluminum foil and bake for 40 minutes. Then, remove the foil and bake for an additional 20 minutes, or until the cheese is golden and bubbly and the potatoes are fork-tender.
6. Cool and serve: Let the casserole cool for 5-10 minutes before serving. Sprinkle with fresh parsley for a pop of color, if desired.

Tip: If the sauce seems too thick, add a splash of milk while whisking. Also, make sure to check the potatoes with a fork to ensure they’re cooked through before removing the casserole from the oven.

Cooking Tips & Techniques

Here are some tips to make sure your ham and potato casserole turns out perfectly:

• Choose the right potatoes: Russet or Yukon Gold potatoes work best because they hold their shape and cook evenly.
• Cut evenly: Ensure your potato slices are thin and uniform to avoid uneven cooking.
• Don’t skip the roux: It’s the key to a creamy, luscious sauce that ties everything together.
• Cover, then uncover: Start with foil on the dish to keep everything moist, then remove it to let the cheese brown beautifully.
• Let it rest: Allow the casserole to cool slightly before serving for the best texture and flavor.

One lesson I learned the hard way—don’t rush the sauce! Whisking gradually and patiently avoids lumps and ensures a silky texture. Also, if your potatoes seem undercooked after the recommended time, simply pop the dish back in the oven for another 5-10 minutes.

Variations & Adaptations

The Ultimate Ham and Potato Casserole is delightfully customizable. Here are some variations to try:

• Vegetarian version: Skip the ham and add sautéed mushrooms, spinach, or roasted broccoli.
• Gluten-free option: Use a gluten-free flour blend for the roux and ensure your ham is gluten-free.
• Cheese swap: Experiment with Swiss, Gouda, or pepper jack for a unique flavor twist.
• Seasonal veggies: Add roasted butternut squash in the fall or zucchini in the summer for extra color and nutrition.

One of my favorite personal adaptations is adding caramelized onions—just cook them low and slow until they’re golden brown and layer them between the ham and potatoes. It adds a subtle sweetness that’s irresistible!

Serving & Storage Suggestions

This casserole is best served warm and fresh out of the oven. Pair it with a crisp green salad or roasted veggies for a complete meal. If you’re hosting, it’s also fantastic with a chilled glass of white wine or a comforting mug of cider.

Got leftovers? Refrigerate the casserole in an airtight container for up to 3-4 days. To reheat, cover it with foil and bake at 350°F (175°C) for about 20 minutes, or until warmed through. You can also freeze portions for up to 2 months—just thaw overnight in the fridge before reheating.

Pro tip: The flavors deepen after a day or two, making leftovers even tastier!
