Step‑by‑Step Instructions for Creamy Leftover Ham and Potato Casserole
Step 1: Preheat the Oven
Begin your Ham Potato Casserole by preheating the oven to 350°F (175°C). This temperature is perfect for achieving that golden, bubbly top while ensuring the casserole heats through evenly. While the oven warms up, get your baking dish ready by greasing it lightly with butter or cooking spray.
Step 2: Sauté the Onions
In a medium saucepan, melt 3 tablespoons of unsalted butter over medium heat. Once the butter is foaming, add in the chopped onion and sauté until they turn translucent, about 4–5 minutes. Stir occasionally to avoid burning and enhance the sweetness of the onions, which will elevate the flavor of your ham and potato casserole.
Step 3: Prepare the Ham and Potatoes
Cut your leftover ham into 1-inch cubes and set aside. Then, peel and cube 2½ lbs of russet or Yukon Gold potatoes, ensuring even-sized pieces for consistent cooking. Bring a pot of water to a boil, add the potato cubes, and parboil them for 5 minutes before draining well. This step helps achieve that perfect creamy texture in your casserole.
Step 4: Make the Cream Sauce
With the sautéed onions ready, sprinkle in 3 tablespoons of all-purpose flour and stir for about 1 minute to cook the flour. Gradually whisk in 2 cups of whole milk, cooking until the sauce thickens—around 5–7 minutes. Season your sauce with 1 teaspoon of salt, ½ teaspoon each of black pepper, ground mustard, and garlic powder for added depth before removing it from heat.
Step 5: Combine the Casserole Ingredients
In a large mixing bowl, combine the cubed ham, parboiled potatoes, and 8 oz of shredded cheddar cheese. Carefully pour the creamy sauce over the mixture and stir until everything is evenly coated. This will ensure that every bite of your Ham Potato Casserole is packed with flavor and creaminess.
Step 6: Bake the Casserole
Transfer the combined mixture to your greased baking dish, spreading it out evenly. Top with any reserved cheese to create a glorious cheesy crust. Place in the preheated oven and bake for 45 minutes, or until the top is golden brown and bubbly. This aromatic dish will fill your kitchen with warmth as it cooks.
Step 7: Let It Rest
Once baked, remove the Ham Potato Casserole from the oven and allow it to rest for 10–15 minutes. This resting period helps the casserole set, making it easier to serve and enhancing its consistency. The aroma wafting through your home will surely tempt everyone to gather around the table for this comforting meal.
Storage Tips for Ham Potato Casserole
Fridge: Store leftovers in an airtight container for up to 4 days to maintain freshness and flavor.
Freezer: For longer storage, freeze in portions for up to 3 months. Make sure to wrap tightly to prevent freezer burn.
Reheating: Reheat in an oven at 350°F for 20-25 minutes if refrigerated, or 35-40 minutes if frozen. Cover with foil to keep it moist and prevent drying out.
Serving Suggestion: When reheating, you can sprinkle a bit of extra cheese on top before baking for a delightful, melty finish to your Ham Potato Casserole.
Make Ahead Options
These Ham Potato Casserole preps beautifully for those hectic weeknights! You can chop your onions, cube the ham, and prepare the potatoes up to 24 hours ahead—just remember to store the potatoes in cold water to prevent browning. Additionally, you can make the creamy sauce and refrigerate it for up to 3 days to save time. When you're ready to serve, simply combine the ham, potatoes, and cheese with the sauce, transfer to your baking dish, and bake in a preheated oven. This not only saves you precious prep time but also ensures a delicious, hearty meal is on the table with minimal effort when it matters most!
