6 medium Yukon Gold Potatoes (Thinly sliced about 1/8 inch using a mandoline for even cooking and creamy texture.)
Salt (Light seasoning enhances flavors.)
Pepper (Light seasoning enhances flavors.)
4 tbsp Butter (Provides rich flavor and helps caramelize the onions.)
1 Yellow Onion (Thinly sliced.)
3 cloves Garlic (Minced.)
1/4 cup All-Purpose Flour (Thickens the sauce.)
1 1/2 cups Half and Half or Milk (Warm before adding to the roux.)
3/4 tsp Dried Rosemary (Infuses an aromatic herbal note.)
1/2 tsp Dried Oregano (Adds earthy complexity.)
1/2 tsp Dried Thyme (Provides subtle floral warmth.)
1/2 tsp Dried Sage (Enhances the smoky turkey ham.)
2 cups Cheddar Cheese (Shredded; reserve 1/2 cup for topping.)
1/2 cup Gruyere Cheese (Shredded.)
1 cup Cooked turkey ham (Diced; reserve some for topping.)
1/4 cup Parmesan Cheese (Finely grated.)
1 tbsp Fresh Parsley (Roughly chopped.)

Foolproof Steps to Scalloped Potato Perfection

Alright, let’s get down to business. Here’s the ridiculously easy process for making these scalloped potatoes and ham:

Prep the Potatoes and Onions: Thinly slice the potatoes using a mandoline (trust me, it’s a game-changer for even cooking) and slice the onion.
Sauté the Aromatics: Melt butter in a large saucepan over medium heat. Add the onion and cook until softened, about 5-7 minutes. Add the garlic and cook for another minute until fragrant.
Make the Cheese Sauce: Stir in the flour and cook for 1 minute to create a roux. Gradually whisk in the warmed half and half (or milk) until smooth. Bring to a simmer, stirring constantly, until the sauce thickens slightly.
Add Flavor: Stir in the rosemary, oregano, thyme, and sage. Season with salt and pepper to taste.
Cheese Time!: Remove from heat and stir in 1 1/2 cups of cheddar cheese and the Gruyere cheese until melted and smooth.
Assemble the Casserole: Grease a 9×13 inch baking dish. Arrange a layer of sliced potatoes on the bottom, followed by a layer of diced ham and some sliced onion. Pour some of the cheese sauce over the top. Repeat layers until all the potatoes, ham, and sauce are used, ending with a layer of sauce.
Top It Off: Sprinkle the remaining 1/2 cup of cheddar cheese and the Parmesan cheese over the top. Add some extra diced ham, if desired.
Bake: Cover the dish tightly with foil and bake at 375°F (190°C) for 45 minutes. Remove the foil and bake for another 15-20 minutes, or until the potatoes are tender and the top is golden brown and bubbly.
Rest and Serve: Let the casserole rest for 10-15 minutes before serving. Garnish with fresh parsley.

Pro Tips for the Ultimate Scalloped Potatoes and Ham

Want to take your scalloped potatoes to the next level? Here are a few insider tips:

Use a Mandoline: For evenly sliced potatoes that cook perfectly. This is the ultimate hack!
Warm the Milk/Half and Half: This helps the cheese sauce come together smoothly and prevents lumps.
Don’t Overcook the Onions: You want them softened, not browned.
Grate Your Own Cheese: Pre-shredded cheese often contains cellulose, which can prevent it from melting smoothly.
Let it Rest: This allows the sauce to thicken slightly and the flavors to meld together.

Common Mistakes to Avoid

Even the easiest recipes can go wrong if you’re not careful. Here are some common mistakes to avoid:

Not Slicing the Potatoes Thin Enough: This can result in potatoes that are still hard in the center.
Overcooking the Potatoes: Nobody wants mushy scalloped potatoes.
Using Cold Milk: This can cause the cheese sauce to seize up.
Forgetting to Season: Salt and pepper are your friends!
Not Covering the Casserole with Foil: This can cause the top to burn before the potatoes are cooked through.

Variations to Spice Things Up

Want to put your own spin on this classic dish? Here are a few ideas:

Add Different Cheeses: Try Gruyere, Swiss, or Gouda for a different flavor profile.
Spice it Up: Add a pinch of red pepper flakes or a dash of hot sauce for a little heat.
Add Veggies: Mix in some sautéed mushrooms, bell peppers, or spinach.
Use Different Meat: Substitute the ham with bacon, sausage, or leftover turkey.
Make it Vegetarian: Omit the ham altogether and add extra veggies.
