1-Getting started with this cheesy ham potato casserole is as easy as turning on your oven. Begin by preheating it to 375°F (191°C) to ensure even baking. This step sets the stage for a dish that’s warm and inviting right out of the oven.

2-Next, parboil the potatoes in boiling water for 5 6 minutes to soften them just enough without making them mushy, then drain and set them aside. Grease a 9×13-inch or 3-4 quart oven-safe dish to prevent sticking and make cleanup a breeze. In the dish, combine the warm potatoes, ham, and 1 cup of shredded cheese, tossing gently to mix.

3-In a skillet, melt the butter over medium heat and add the onion and garlic, cooking until softened for about 3 minutes. Stir in the salt, pepper, smoked paprika, ground mustard, parsley, and flour until everything combines and the flour absorbs the liquid. Reduce the heat to low, gradually add the milk, and simmer for 3 5 minutes until it thickens into a gravy-like sauce.

4-Pour this warm sauce over the ham and potato mixture in the dish, tossing gently to coat everything evenly. Bake covered with foil for 30 minutes, then remove the foil and sprinkle the remaining cheese on top. Bake uncovered for 5 10 minutes until the cheese melts and the casserole bubbles.

5-Finally, garnish with fresh herbs or hot sauce before serving, and let it rest a bit. For more casserole inspiration, try our creamy cheesy baked macaroni recipe to expand your options.
