The Recipe: Loaded Scalloped Potatoes

Ingredients

  • 2 lbs Yukon Gold or Russet potatoes (thinly sliced, skin-on for Yukons)
  • 4 oz Boar’s Head Gruyère cheese, shredded
  • 4 oz Boar’s Head Vermont Cheddar cheese, shredded
  • 1 large yellow onion, thinly sliced & caramelized
  • 6 slices Boar’s Head thick-cut bacon, cooked & crumbled
  • 2 cups whole milk
  • 3 tbsp Cobram Estate extra virgin olive oil (or high-quality olive oil)
  • 3 tbsp butter
  • 3 tbsp all-purpose flour
  • 2 cloves garlic, minced
  • 1 tsp fresh thyme leaves
  • 1 tsp salt
  • ½ tsp black pepper
  • ¼ tsp nutmeg (optional, for depth)

Instructions

1. Prep the Potatoes & Onions

  • Thinly slice potatoes (1/8″ thick) using a mandoline for even cooking.
  • Caramelize onions: Heat 1 tbsp olive oil in a skillet over medium-low heat. Add onions, cooking slowly for 20-25 minutes until golden brown.

2. Make the Cheese Sauce (Roux)

  • In a saucepan, melt butter over medium heat.
  • Whisk in flour and cook for 1-2 minutes (don’t let it brown).
  • Gradually whisk in milk until smooth.
  • Stir in garlic, thyme, salt, pepper, and nutmeg. Simmer until thickened (~5 mins).
  • Remove from heat and stir in 1 cup of the mixed cheeses until melted.

3. Layer the Scalloped Potatoes

  • Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish with olive oil.
  • Layer in this order:
  1. Potatoes (slightly overlapping)
  2. Caramelized onions & crumbled bacon
  3. Cheese sauce
  • Repeat layers, ending with sauce.

4. Bake to Golden Perfection

  • Cover with foil and bake for 45 minutes.
  • Uncover, top with remaining cheese, and bake 15-20 more minutes until bubbly and golden.
  • Let rest 10 minutes before serving (sauce will thicken).
