How to Make Warm Christmas Ham Casserole

1. Preheat the oven to 350 °F (175 °C). This ensures our casserole cooks evenly and develops that perfect bubbling golden top as it bakes.

2. Combine diced leftover ham, cooked pasta or potatoes, chopped onion, and minced garlic in a large bowl. Give it a good stir to mix all those incredible flavors together until evenly distributed.

3. Melt the butter in a saucepan over medium heat until it becomes foamy. Whisk in the all-purpose flour for about 1 2 minutes until it turns a light golden color, creating a roux that will thicken our delicious cheese sauce.

4. Pour in milk gradually while whisking continuously. Simmer until the mixture is smooth and thickens, then stir in the shredded cheese and Dijon mustard. Season with salt and pepper to your liking for an extra flavor boost!

5. Mix the creamy cheese sauce into the ham mixture, stirring gently to coat all ingredients with that luscious sauce.

6. Transfer everything into a greased 9×13-inch baking dish, spreading it evenly. Bake for 20 25 minutes, or until it s bubbly and golden brown on top a sight that will make your kitchen feel like a holiday celebration!

7. Let stand for 5 minutes to cool slightly, then garnish with fresh thyme or parsley before serving. This little touch elevates the dish with a pop of color and flavor.

Optional: Serve with a side of garlic bread for an extra touch of deliciousness!
