Step‑by‑Step Instructions for Ham and Potato Au Gratin

Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven heats up, grab a 2-quart casserole dish and grease it lightly with butter or non-stick spray. This will help prevent sticking and promote even browning. Set the dish aside for layering your delectable Ham and Potato Au Gratin.

Step 2: Layer the Potatoes and Ham
Carefully layer half of your thinly sliced potatoes in the bottom of the greased casserole dish. Next, sprinkle half of the diced ham and chopped onion over the potatoes, creating a satisfying blend of flavors. Repeat this layering process with the remaining potatoes, ham, and onions, ensuring an even spread to build a flavorful base.

Step 3: Make the Cheese Sauce
In a medium saucepan, melt 3 tablespoons of butter over medium heat until bubbly. Once melted, add 3 tablespoons of all-purpose flour, stirring constantly for about 1 minute to form a roux. This forms the foundation of your creamy cheese sauce, which will beautifully envelop the layers of potatoes and ham.

Step 4: Whisk in the Milk
Gradually whisk in 2 cups of milk into the roux, combining until smooth. Let this mixture simmer for approximately 3-5 minutes, stirring regularly, until it thickens slightly. The sauce will begin to bubble gently; this means it’s ready for seasoning with ½ teaspoon salt, ¼ teaspoon pepper, and ¼ teaspoon paprika for a touch of flavor.

Step 5: Add the Cheddar Cheese
Once the sauce is seasoned, stir in 1 cup of shredded sharp cheddar cheese until fully melted and creamy. The cheese should blend into the sauce beautifully, creating a rich coating for your layered ingredients. Pour this luscious cheese sauce evenly over the layered potatoes and ham in your casserole dish, ensuring every component gets a luxurious coating.

Step 6: Bake Covered
Cover the dish tightly with aluminum foil and place it in the preheated oven. Bake for 60 minutes, allowing your Ham and Potato Au Gratin to cook thoroughly. During this time, the potatoes will soften, and the flavors will meld beautifully, creating a comforting dish that’s sure to warm your heart.

Step 7: Finish Baking Uncovered
After an hour, carefully remove the foil. Sprinkle ½ cup of grated Parmesan cheese evenly over the top of your casserole. Return the dish to the oven and bake uncovered for an additional 20-30 minutes. Look for a golden, bubbly crust as a visual cue that your Ham and Potato Au Gratin is ready to be enjoyed.

Step 8: Rest Before Serving
Once beautifully browned, remove the dish from the oven and let it rest for about 5-10 minutes. This essential step allows the flavors to settle and makes serving easier. Your Ham and Potato Au Gratin is now ready to be served, with every layer infused with creamy goodness and memories of delightful family gatherings.
