Ingredients

3 pounds russet potatoes diced
¼ cup salted butter
½ white onion diced
1 teaspoon red pepper flakes
1 teaspoon white ground mustard
1 teaspoon garlic powder
1 teaspoon paprika
⅓ cup flour
1 ½ cups heavy cream
1 ½ cups medium cheddar cheese
8 ounces sliced deli ham diced

Instructions

Preheat the oven to 350°F.
In a large pot, cover the potatoes with water and place over high heat. Bring the water to a boil and then reduce the heat to low. Allow the potatoes to cook for 15 minutes.
Drain the potatoes and set them aside. In a large skillet, melt the butter over medium-high heat. Once the butter is completely melted, add the onions and spices. Cook the onions for about 5 minutes, or until soft and translucent.
Stir in the flour until it evenly coats the onions. Add the heavy cream and continue cooking the mixture on high heat until the cream begins to form bubbles.
Once the cream begins to form bubbles, stir in the cheese until it is completely melted.
Transfer the cheese sauce to a 9x13 inch baking dish along with the diced potatoes and sliced ham. Fold the ingredients together until the potatoes and ham are completely covered in sauce.
Cook the casserole for 20-25 minutes, or until bubbly.
Serve and enjoy!

Notes

Ingredient Flexibility:

While I recommend medium cheddar cheese for the best flavor balance, feel free to substitute with any variety of cheddar that suits your taste preferences.
Peeling the potatoes is completely optional—I often leave the skins on for added nutrition and rustic texture, but remove them if you prefer a smoother finish.

Customization Options:

For added crunch, I sprinkle panko or regular breadcrumbs over the top before baking to create a delightfully crispy contrast to the creamy interior.
You can stir a few dashes of hot sauce like Tabasco directly into the melted cheese sauce for a spicy kick that warms you from the inside out.

Serving Suggestions:

Pair this rich casserole with a fresh green salad, steamed vegetables, or crusty bread to balance the creamy, cheesy goodness with lighter elements.

Storage Tip:

Keep leftovers covered with plastic wrap directly in the baking dish or transfer to an airtight container for easier storage. Refrigerate for up to 5 days to maintain optimal freshness and flavor.
