How to Make Ham and Potato Au Gratin
Preheat the oven to 350 °F (175 °C). This creates the perfect environment for your casserole to cook evenly and get that lovely golden finish on top.
Melt the butter in a skillet over medium heat. Add the chopped onion and saut until it becomes translucent, which will take about 2-3 minutes. This adds a wonderful sweetness to your dish.
Stir in the flour and cook for 1 minute, creating a roux. This step is crucial as it helps to thicken the creamy sauce later on.
Gradually whisk in the milk. Keep stirring continuously until the mixture thickens, about 5-7 minutes. You want it to coat the back of a spoon for that perfect creamy texture.
Season the sauce with salt, pepper, and paprika. Taste and adjust according to your preferences for a flavorful, well-balanced sauce.
Layer half of the sliced potatoes in a greased baking dish, followed by half of the ham. This building process helps create those amazing layered flavors in each bite.
Pour half the creamy sauce over the layers. Repeat with the remaining potatoes, ham, and sauce to ensure every layer is well-coated in deliciousness.
Top generously with shredded cheddar and grated Parmesan cheese. This will create that irresistible cheesy crust everyone loves.
Cover the dish with aluminum foil and bake for 25 minutes. After that, remove the foil to bake for an additional 10-15 minutes, until the cheese is bubbly and golden brown.
Cool slightly before serving. Letting it rest for about 5 minutes helps the casserole set up nicely.
Optional: Garnish with chopped parsley for a fresh pop of color and flavor!

Veggie Boost: Add broccoli or spinach for an extra touch of nutrition and color that brightens every bite. These greens provide a fresh contrast to the creamy layers.
Protein Swap: Replace ham with shredded chicken or turkey for a lighter option, or use a vegetarian sausage for a delightful meatless variant. Each choice brings its own unique flavors to the dish.
Cheese Mix: Experiment by incorporating Gruy re or Monterey Jack cheese for a twist in flavor. Mixing different cheeses can create a richer, more complex taste profile.
Bake with Bread Crumbs: Top with buttered bread crumbs before baking for a delightful crunch that contrasts wonderfully with the creamy casserole underneath. It adds an enjoyable texture when digging in!
Spicy Kick: Stir in some jalape os or a sprinkle of cayenne pepper to elevate the heat level. This twist adds a fiery depth that keeps your taste buds engaged.
Herb Infusion: Enhance flavors by adding fresh thyme or parsley to the sauce. They not only contribute freshness but also a lovely aromatic quality to the dish.
Sweet Surprise: Toss in some caramelized onions or a handful of frozen peas. These additions introduce subtle sweetness and color, making each serving even more inviting.

Are there any dietary considerations I should be aware of?
Great question! If you re accommodating allergies or dietary preferences, swap the regular milk for a non-dairy alternative like almond or oat milk. You can also use gluten-free flour in the sauce for those with gluten sensitivities. If you have pets, be cautious not to let them indulge in any leftovers that contain onions or excessive cheese as those can be harmful to them.
How can I prevent my cheesy sauce from being too thin?
To ensure a thicker sauce that coats well, remember to cook your roux (butter and flour mixture) for at least a minute before adding the milk. When you whisk in the milk, continue to stir until the sauce thickens and coats the back of a spoon, which typically takes about 5-7 minutes. If it s still too thin after that, allow it to simmer a little longer while stirring continuously!
