These creamy Three Cheese Scalloped Potatoes are layers of deliciousness! With cheddar, mozzarella, and parmesan, every bite melts in your mouth.
Honestly, who can say no to cheesy potatoes? They make the perfect side for any meal. I love serving them hot and bubbly—it’s comfort food at its best!
Key Ingredients & Substitutions
Potatoes: Yukon Gold potatoes are my favorite for their creamy texture, but Russet potatoes work well too. If you’re looking for a lower-carb option, try using cauliflower instead, though the texture will differ.
Cheeses: The combination of sharp cheddar, Gruyère, and Parmesan delivers a great flavor mix. If you prefer a milder taste, use Monterey Jack in place of sharp cheddar. For a gourmet touch, you can also use a mix of goat cheese and mozzarella.
Milk: Whole milk makes the sauce rich and creamy. For a lighter version, you can swap it with 2% milk or unsweetened almond milk, noting that the sauce may be less creamy.
Thyme: Fresh thyme adds a wonderful herbal flavor. If fresh isn’t available, dried thyme works in a pinch—just use less as it’s more concentrated.
How Do I Make a Creamy Cheese Sauce Without Lumps?
The cheese sauce can be a tricky part of this recipe, but it’s key for that creamy texture! Here’s how to get it just right:
- Start with melted butter. Add flour and cook for a minute to form a smooth roux, stirring continuously to avoid burning it.
- Whisk in the milk gradually, making sure to mix well. This prevents lumps from forming—keep whisking until the sauce thickens and comes to a bubble.
- Remove from heat and stir in the spices and cheeses. Make sure the cheese melts smoothly into the sauce for the best flavor.
Taking your time with each step is essential, especially when mixing in the milk and cheese!
How to Make Three Cheese Scalloped Potatoes
Ingredients You’ll Need:
For The Dish:
- 4 cups (about 2 lbs) thinly sliced potatoes (Yukon Gold or Russet)
- 2 cups sharp cheddar cheese, shredded
- 1 cup Gruyère cheese, shredded
- 1 cup Parmesan cheese, grated
For The Sauce:
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 ½ cups whole milk
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon fresh thyme leaves (plus extra for garnish)
- Salt and freshly ground black pepper, to taste
- Optional: pinch of nutmeg for sauce
- Cooking spray or extra butter (for greasing the baking dish)
How Much Time Will You Need?
This delicious recipe takes about 15 minutes to prep and approximately 1 hour of baking time. So, plan for about 1 hour and 15 minutes from start to finish. You’ll enjoy layers of tender potatoes baked in a creamy, cheesy sauce that’s perfect for any meal!
Step-by-Step Instructions:
1. Preheat and Prepare:
Start by preheating your oven to 375°F (190°C). While it’s heating up, grease a baking dish with butter or cooking spray to prevent sticking.
2. Make the Roux:
In a medium saucepan over medium heat, melt the butter until it’s bubbly. Once melted, whisk in the flour and keep stirring for about 1-2 minutes. This will form a roux—just make sure it doesn’t turn brown!
3. Create the Cheese Sauce:
Next, gradually whisk in the milk while stirring constantly to avoid lumps. Cook the mixture until it thickens and starts to bubble, stirring often. Remove from the heat and add the garlic powder, onion powder, thyme leaves, salt, pepper, and a pinch of nutmeg if you like.
Now, stir in half of the sharp cheddar and Gruyère cheeses along with all of the Parmesan. Mix until the cheese melts and you have a smooth, creamy sauce!
4. Layer the Potatoes:
In your greased baking dish, arrange about half of the sliced potatoes in an even layer. Pour half of the delicious cheese sauce over these potatoes. Then, add the remaining potatoes on top in another even layer.
5. Finish with Sauce and Cheese:
Pour the rest of the cheese sauce evenly over the top layer of potatoes. Don’t forget to sprinkle the rest of the cheddar and Gruyère cheeses on top for that irresistible stretch!
6. Bake to Perfection:
Cover the dish tightly with aluminum foil and bake for 45 minutes. After that, take off the foil and continue baking for another 20-30 minutes. You’ll know it’s ready when the top is golden brown and bubbling, and the potatoes are tender when pierced with a fork.
7. Let It Rest and Serve:
Before serving, let your beautiful scalloped potatoes rest for 10 minutes. This will help everything set up nicely. Garnish with a few fresh thyme leaves, and then serve warm to your hungry guests!
This dish features layers of tender potatoes baked in a creamy cheese sauce made from three kinds of cheese, creating a rich and comforting side perfect for family dinners or holiday meals. Enjoy!
Can I Use Different Types of Cheese?
Absolutely! While the combination of sharp cheddar, Gruyère, and Parmesan is delightful, feel free to experiment with cheeses like Monterey Jack for a milder flavor or use any favorite melting cheese you have on hand.
What Should I Do if My Sauce is Too Thick?
If your cheese sauce turns out too thick, just whisk in a little extra milk over low heat until you reach your desired consistency. This works well to maintain a creamy texture for your scalloped potatoes.
Can I Make This Ahead of Time?
Yes! You can prepare the dish up to the baking stage, cover it tightly, and refrigerate for up to 24 hours. When ready to bake, add an extra 10-15 minutes to the baking time since it will be starting cold from the fridge.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. Reheat gently in the microwave or in the oven at 350°F (175°C) until warmed through. Cheese may lose some texture but will still taste fabulous!
