Equipment

  • Before you start, gather these kitchen essentials:

Method
 

  1. Follow these easy, step-by-step instructions to create the ultimate creamy, cheesy scalloped potatoes that will wow your guests.
Step 1: Preheat the Oven
  1. Preheat your oven to 375°F (190°C).
  2. Grease a 9x13-inch baking dish lightly with butter or olive oil.
Step 2: Prepare the Potatoes
  1. Peel the Yukon Gold potatoes and slice them thinly — about ⅛ inch thick — using a mandoline slicer for even layers.
  2. Place them in a bowl of cold water to prevent browning while you prepare the sauce.
  3. Pro Tip: Thin, even slices ensure the potatoes cook uniformly and soak up the creamy sauce perfectly.
Step 3: Sauté the Aromatics
  1. In a medium saucepan, heat olive oil or butter over medium heat.
  2. Add the chopped onion and sauté for 3–4 minutes until soft and translucent.
  3. Stir in the garlic and thyme and cook for another 30 seconds until fragrant.
  4. The aroma of garlic and thyme sets the stage for the rich, savory sauce that makes this dish unforgettable.
Step 4: Make the Cream Sauce
  1. Lower the heat slightly and whisk in the Dijon mustard — it adds a subtle tang that enhances the creaminess.
  2. Pour in the whole milk and heavy cream, whisking constantly to combine.
  3. Add the salt and black pepper.
  4. Stir occasionally and let the mixture warm gently until it begins to thicken slightly — about 5 minutes.
Step 5: Add the Cheese
  1. Remove the saucepan from heat.
  2. Stir in Gruyère cheese and half of the Parmesan cheese until melted and smooth.
  3. Taste and adjust seasoning as needed.
  4. You now have a rich, velvety garlic-cheese sauce — the heart of your scalloped potatoes.
Step 6: Layer the Potatoes
  1. Drain the potato slices and pat them dry with a clean towel.
  2. Arrange half of the potato slices evenly in the prepared baking dish.
  3. Pour half of the cream-cheese mixture over them.
  4. Add the remaining potato slices, then pour the rest of the sauce on top, spreading it evenly to cover all the layers.
  5. For a perfectly even bake, gently tap the dish on the counter to remove air pockets between the layers.
Step 7: Top & Bake
  1. Sprinkle the remaining Parmesan cheese evenly on top.
  2. Cover the dish with foil and bake for 40 minutes.
  3. Remove the foil and bake for another 20–25 minutes until the top is golden brown and bubbly.
  4. Test with a knife — it should glide easily through the potatoes when they’re done.
  5. For an even more golden finish, broil the top for 2–3 minutes before serving (watch closely!).
Step 8: Rest & Garnish
  1. Let the casserole rest for 10 minutes before serving — this allows the sauce to thicken slightly.
  2. Garnish with chopped fresh parsley for a pop of color and freshness.
  3. Serve warm, and get ready for the “oohs” and “ahhs” from everyone around the table! 🧡

❓ 10 FAQs
1. Can I make scalloped potatoes ahead of time?
Yes! Assemble the dish a day before, refrigerate, and bake just before serving.
2. Can I use Russet potatoes instead of Yukon Gold?
Yes, but Yukon Golds hold their shape better and give a creamier texture.

It’s up to you! The skin adds rustic charm and texture, but peeled potatoes make it extra smooth.
4. Can I make it without cheese?
You can — it will still be creamy and delicious, but the cheese adds rich depth and body.

The cheese may have overheated. Always add cheese off heat and stir gently.
