When you’re making this scalloped potatoes recipe, just make sure to slice the potatoes thin and  even, with consistent cuts. You don’t want to have a mix of thin and thick slices because the casserole won’t cook evenly. The thicker the potato slices, the longer it will take to cook. Be careful and try to cut them thin with a mandoline (we highly recommend using a cut-safe glove with a mandoline) or sharp knife. Yukon Gold Potatoes are our favorite because they're more creamy and tender than russets.

Ingredients

for the potatoes:

• 3 pounds (1.36 kg) Yukon Gold or Russet Potatoes , peeled and sliced thin
• 2 cups (224 g) shredded Cheese , divided
• Optional- 1 small onion , sliced thin

for the mushroom gravy

• 1/2 cup (113.5 g) butter , divided
• 16 ounces (454 g) mushrooms , sliced
• 2 cloves garlic , minced
• 1/3 cup (42 g) flour
• 1 cup (240 ml) broth (beef, chicken or vegetable)
• 2 cups (480 ml) milk
• salt to taste
• black pepper to taste

Instructions 

• Preheat oven to 375°F. Butter an 9”x13” baking dish. Set aside.
• Make the gravy: In saucepan, melt half of butter (1/4 cup) over medium-high heat.  Add garlic, cook until softened and then add mushrooms and cook until mushrooms are golden brown and excess mushroom liquid evaporates, about 5-10 minutes.
• Add remaining butter and cook until melted. Stir in the flour, cooking and stirring to remove lumps. Add about 1/2 cup of stock, whisking until incorporated.
• Pour in the remaining broth and milk. Whisk until well combined. Season with salt and pepper, to taste (the saltiness and flavors will concentrate some when it reduces down).
• Reduce heat to medium, stirring often, simmer until slightly thickened, about 15-20 minutes. Check for seasoning and salt again if needed. Remove from heat and set aside.
• Layer 1/2 of the potatoes in the prepared baking dish, making sure to separate slices. Top with half of the gravy. Layer half of the sliced onions. Layer about 1/2 of the cheese over the potatoes.
• Top with the remaining potatoes (making sure to separate slices). Top with remaining gravy, onions and cheese.
• Cover the pan with aluminum foil. Bake for 1 hour, the remove foil and bake uncovered for about 25-30 minutes or until top is golden and potatoes are cooked through. Serve warm. Note: If you're using a smaller and taller baking dish than a 9"x13", it might take a little longer to cook because the volume of potatoes are higher and thicker.
