Ingredients
- 70 pounds Russet potatoes
- 35 pounds Diced ham
- 7 cups Butter
- 7 cups All-purpose flour
- 18 quarts Whole milk
- 21 pounds Shredded cheddar cheese
- 7 cups Grated Parmesan cheese
- 7 tablespoons Salt
- 3.5 tablespoons Ground black pepper
- 3.5 tablespoons Garlic powder
- 7 pounds Onions, finely chopped
- 4 cups Parsley, chopped (optional garnish)
- 14 spray applications Nonstick cooking spray
Directions
Step 1
Preheat the oven to 350°F (175°C).
Step 2
Using nonstick cooking spray, grease approximately 14 large (full-sized) aluminum catering pans.
Step 3
Peel the russet potatoes and slice them into thin, uniform rounds (about 1/8 inch thick). Place them in cold water to prevent browning while you prepare the other ingredients.
Step 4
In a large stockpot, melt the butter over medium heat. Add the chopped onions and sauté until soft and translucent, about 5-7 minutes.
Step 5
Whisk in the flour and cook for 2-3 minutes to remove the raw flour taste, creating a roux.
Step 6
Gradually pour in the milk, whisking constantly to create a smooth sauce. Bring to a light simmer and let thicken slightly, about 5-7 minutes.
Step 7
Add the shredded cheddar cheese and grated Parmesan cheese to the sauce, stirring until fully melted and incorporated.
Step 8
Season the cheese sauce with salt, black pepper, and garlic powder. Adjust seasoning to taste.
Step 9
Drain the sliced potatoes and layer them in the prepared pans, alternating with layers of diced ham. Aim for 2-3 layers in each pan.
Step 10
Pour the cheese sauce evenly over the layers of potatoes and ham, ensuring all pieces are well coated.
Step 11
Cover each pan tightly with aluminum foil. Place in the preheated oven and bake for 90 minutes.
Step 12
After 90 minutes, remove the foil and bake for an additional 20-30 minutes, or until the top is golden brown and the potatoes are fork-tender.
Step 13
Remove from oven and let cool slightly for 10-15 minutes. Sprinkle with chopped parsley before serving, if desired.
Step 14
Serve warm and enjoy this crowd-pleasing dish!
