How to Make Ham and Potato Au Gratin
Preheat your oven to 375 °F (190 °C). This step ensures that your casserole cooks evenly and develops that delicious golden top.
Melt the butter in a saucepan over medium heat. Add the chopped onion and saut until it becomes translucent, releasing a sweet aroma that will elevate your dish.
Sprinkle the flour over the onions, whisking continuously for about 1-2 minutes. This step creates a roux that will thicken your cheese sauce beautifully.
Whisk in the milk gradually, stirring until the mixture thickens and bubbles. You ll want to keep it smooth and creamy, resembling a luscious sauce.
Season the sauce with salt, pepper, and paprika. Then, stir in the shredded cheddar and grated Parmesan, allowing them to melt into the sauce for that cheesy goodness.
Combine sliced potatoes, diced ham, and your creamy cheese sauce in a large bowl. Mix gently until everything is evenly coated and every bite promises rich flavor.
Transfer the mixture into a greased casserole dish. Cover it with foil and bake for 25 minutes to get everything perfectly melded together.
Uncover the casserole and bake for an additional 5-10 minutes, until the top is golden and bubbly. This gives it that irresistible crispy crust.
Optional: Garnish with fresh herbs or a sprinkle of breadcrumbs for added texture and flavor.
