Ham & Cheese Scalloped Potatoes

Creamy scalloped potatoes from the BEST base recipe for a classic, homemade scalloped potato casserole plus leftover ham and swiss cheese.

📝 Ingredients

• 2 lbs potatoes, peeled
• 1 medium onion, thinly sliced
• 3 cups chopped ham
• 1/4 cup butter
• 1/4 cup flour
• 3 cups milk
• 1 teaspoon salt
• 1/2 teaspoon pepper
• 1/2 teaspoon dried thyme
• 1/2 teaspoon dry mustard powder
• 8 oz swiss cheese, shredded

👨‍🍳 Instructions

1. 1Preheat oven to 375 degrees. Spray a 3-quart baking dish with cooking spray.
2. 2Melt butter over medium heat in a saucepan then whisk in flour. Cook and whisk flour and butter for 2 minutes.
3. 3Add salt, pepper, thyme and mustard powder then whisk in milk. Cook and whisk approximately 3-5 minutes or until smooth and thickened. Aim for the thickness of a sauce, not a thick gravy. Remove from heat.
4. 4Slice potatoes very thinly (no thicker than 1/8 inch) then add a single layer of potatoes to the bottom of the prepared baking dish.
5. 5Layer on 1/3 of the ham and 1/3 of the onions.
6. 6Add another single layer of potatoes then repeat the layers twice more, ending with potatoes on top.
7. 7Whisk the sauce once again. If it has thickened too much, add a little milk. Again, we’re looking for a sauce, not thick gravy.
8. 8Pour sauce evenly over layered ingredients then sprinkle cheese on top.
9. 9Bake, uncovered, for 1 hour and 15 minutes, covering loosely with foil when cheese starts to brown.
10. 10Remove foil then continue baking for 15-20 minutes longer or until cheese is golden brown and potatoes are tender.
