Cheesy Scalloped Potatoes with Ham

Follow our step-by-step guide on how to make Cheesy Scalloped Potatoes with Ham.

1. Step 1

   Begin by preheating your oven to a cozy 350°F (175°C) and lightly greasing a 9x13-inch baking dish with cooking spray to ensure easy serving later.

2. Step 2

   In a large pot, bring water to a rolling boil and add your sliced potatoes.

3. Step 3

   Cook them until they’re just shy of tender, about 5 to 10 minutes, then drain and rinse them under cold water to cool.

4. Step 4

   Let them sit in the colander to ensure they’re well-drained.

5. Step 5

   Meanwhile, in a large skillet over medium heat, melt some butter and toss in the chopped onion, sautéing until it softens, which should take around 5 minutes.

6. Step 6

   Stir in flour, Dijon mustard, salt, and pepper, cooking for an additional minute to create a flavorful base.

7. Step 7

   Gradually whisk in milk, stirring continuously until the sauce thickens, which will take about 5 minutes.

8. Step 8

   Once thickened, fold in the shredded Cheddar cheese until it melts into a creamy delight.

9. Step 9

   Now, it’s time to build your layers: start with half of the cooked potatoes in the bottom of your prepared dish, followed by 1 ½ cups of diced ham and half of that luscious cheese sauce.

10. Step 10

    Repeat this layering process with the remaining potatoes, ham, and cheese sauce, creating a hearty masterpiece.

11. Step 11

    Slide your dish into the preheated oven and bake for approximately 1 hour, or until the top is beautifully golden and bubbly, filling your kitchen with an irresistible aroma.
