Kitchen Tools You’ll Need
- Mandoline slicer or sharp knife
- 9×13-inch baking dish
- Medium saucepan
- Whisk and spoon
- Measuring cups and spoons
- Aluminum foil
- Oven thermometer (optional but helpful)
Step-by-Step Instructions
🔪 Step 1: Prepare the Potatoes
Start by preheating your oven to 375°F (190°C). Grease your baking dish with butter or a nonstick cooking spray.
Wash, peel, and thinly slice the potatoes. Ideally, they should be ⅛ inch thick. A mandoline slicer ensures uniform slices, which helps the potatoes cook evenly and absorb the cheese sauce perfectly.
Pro Tip: Soak the sliced potatoes in cold water for 15 minutes to remove excess starch. Pat dry thoroughly to ensure the sauce sticks to the slices.
🧄 Step 2: Make the Cheese Sauce
In a saucepan over medium heat, melt the butter. Add minced garlic and sauté for about 1 minute until fragrant. Pour in the heavy cream and bring it to a gentle simmer—don’t boil.
Whisk in the salt, pepper, paprika, and thyme. Then gradually stir in 1½ cups of cheddar cheese and all of the mozzarella. Continue stirring until the cheese has melted completely and the sauce is silky smooth.
Avoiding Curdling: Don’t let the sauce boil. Keep it at a low simmer and stir constantly.
🧀 Step 3: Assemble the Dish
Layer half of the sliced potatoes in the bottom of your baking dish. Pour half of the cheese sauce evenly over the top. Spread it with a spatula to make sure every slice is coated.
Repeat with the remaining potatoes and cheese sauce. Finish by sprinkling the top with the remaining ½ cup of cheddar cheese and optional Parmesan cheese for a golden, flavorful crust.
🔥 Step 4: Bake to Perfection
Cover the dish with aluminum foil and bake for 45 minutes. Then remove the foil and bake uncovered for an additional 20–25 minutes, or until the top is bubbly and lightly browned.
Insert a fork into the center—if it goes through easily, the potatoes are done.
🌿 Step 5: Let Rest, Garnish & Serve
Let the dish rest for at least 10 minutes before serving. This allows the cheese sauce to set slightly and enhances the flavor.
Garnish with dried or fresh thyme for a pop of color and herbal aroma.
