Ham and Cheese Casserole: The Ultimate Thanksgiving Leftovers Makeover

For me, Thanksgiving isn’t just about the grand feast on Thursday; it’s about the days that follow, brimming with possibilities. My grandmother, a wizard with leftovers, always had a plan. While everyone else groaned at the thought of turkey sandwiches for the third day running, she’d unveil a bubbling, golden-brown casserole. The aroma alone, a comforting blend of savory ham, creamy potatoes, and melted cheese, was enough to banish any leftover fatigue. This Ham and Cheese Casserole, her signature creation, transformed the familiar into something exciting and new, a warm hug on a chilly autumn day.

Recipe Overview

• Prep Time: 10 minutes
• Cook Time: 30-35 minutes
• Total Time: 40-45 minutes
• Servings: 4-6
• Yield: 1 casserole
• Dietary Type: Varies (see variations)

Ingredients

• 1 1/2 cups cooked mashed white potatoes (DO NOT USE MASHED SWEET POTATOES)
• 2 cups ham (cooked, chopped)
• 1/3 cup mayonnaise (not lowfat)
• 1 (10 1/2 ounce) can cream of mushroom soup
• 1 1/2 cups croutons, slightly crushed
• 1/4 cup milk
• 2/3 cup cheddar cheese, cubed
• Dry breadcrumbs (for topping)
• 1/4 cup cheddar cheese, grated (for topping)

Equipment Needed

• 2-quart casserole dish
• Non-stick vegetable oil spray
• Medium-sized mixing bowl
• Measuring cups and spoons

Instructions

1. Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius).
2. Spray a 2-quart casserole dish with non-stick vegetable oil spray. This ensures the casserole doesn’t stick and makes cleaning a breeze.
3. Spread a good layer (about 1/2 inch thick) of mashed potatoes along the bottom of the casserole dish. Make sure it’s an even layer to create a solid base for the rest of the ingredients. Using white potatoes is key for the right texture and flavor profile. Sweet potatoes, while delicious, will significantly alter the taste.
4. In a medium-sized mixing bowl, combine the chopped ham, mayonnaise, cream of mushroom soup, slightly crushed croutons, milk, and cubed cheddar cheese. Mix everything together until it’s well combined. The mayonnaise adds a creamy richness, while the cream of mushroom soup contributes a savory depth.
5. Layer this mixture on top of the mashed potatoes in the casserole dish, spreading it evenly.
6. Sprinkle the top of the casserole with the grated cheddar cheese, followed by a slight layer of dry breadcrumbs. This creates a beautiful golden-brown crust.
7. Bake in the preheated 350-degree Fahrenheit oven for 30 to 35 minutes, or until the top is nicely browned and bubbly. To check for doneness, insert a knife into the center; it should come out hot. Be sure to watch it closely during the last few minutes to prevent over-browning.
8. Serve hot with those leftover Thanksgiving rolls or biscuits!

Expert Tips & Tricks

• Crispier Croutons: For extra crunchy croutons, lightly toast them in a skillet with a little butter before adding them to the casserole mixture.
• Mushroom Soup Upgrade: Instead of canned cream of mushroom soup, you can make your own using fresh mushrooms, butter, flour, broth, and cream. This will elevate the flavor of the casserole to a whole new level.
• Cheese Variety: Don’t be afraid to experiment with different cheeses! Gruyere, Monterey Jack, or a blend of cheddar and mozzarella would all be delicious additions.
• Make-Ahead Magic: Assemble the casserole ahead of time, cover it tightly with plastic wrap, and store it in the refrigerator for up to 24 hours. Add the breadcrumb topping just before baking. This makes it a perfect dish for busy weeknights or potlucks.
• Prevent Soggy Casserole: If you’re worried about the casserole becoming soggy, you can lightly toast the mashed potatoes in the oven before adding the other ingredients. This will help to create a barrier and prevent the casserole from absorbing too much moisture.

Serving & Storage Suggestions

Serve the Ham and Cheese Casserole hot, straight from the oven. It pairs perfectly with leftover Thanksgiving rolls, biscuits, or a simple green salad. For a more complete meal, add a side of steamed green beans or roasted asparagus.

Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days.

Reheating: Reheat individual portions in the microwave or toaster oven until heated through. For a larger portion, reheat in the oven at 350 degrees Fahrenheit until warmed through.

Freezing: While the casserole can be frozen, the texture may change slightly upon thawing. If you plan to freeze it, allow the casserole to cool completely before wrapping it tightly in plastic wrap and aluminum foil. Freeze for up to 2 months. Thaw in the refrigerator overnight before reheating.
