This cheesy scalloped potato bake is a warm, comforting dish that’s perfect for any meal! With layers of thin potatoes and creamy cheese, it’s a delicious treat for everyone.
I always love the way the cheese bubbles up on top—it’s like a warm hug on a plate. Sometimes, I sneak in extra cheese because, well, you can never have too much! 🧀
Key Ingredients & Substitutions
Potatoes: Russet potatoes are perfect for this dish because they’re starchy and fluffy. If you want a creamier texture, you can use Yukon Gold potatoes instead. They hold their shape well too.
Cheese: Sharp cheddar is a must for flavor. Gruyère is optional, but I love the nutty taste it adds. You can swap it for Swiss cheese or even Monterey Jack if preferred.
Heavy Cream: This adds richness to the sauce. If you’re looking to lighten it up, you can replace some or all of it with half-and-half or whole milk, but keep in mind it may be less creamy.
Butter: Unsalted butter is recommended for better control of the seasoning. If you’re looking for a dairy-free option, try using olive oil or a dairy-free butter substitute.
Garlic: Fresh minced garlic is best, but you can use garlic powder in a pinch. Use about 1/8 teaspoon of garlic powder for each clove.
How Do I Make Sure My Cheese Sauce is Smooth?
Getting a smooth cheese sauce is crucial for the best flavor and texture. Here’s how you can achieve that:
- Start by making a roux: Cook the butter and flour until it’s just bubbling, without browning.
- Gradually whisk in the milk and cream, making sure no lumps form.
- Cook it gently on medium heat, whisking constantly. The sauce will thicken as it heats.
- Turn off the heat before adding cheese, allowing it to melt evenly without clumping. Stir slowly until fully combined.
Cheesy Scalloped Potatoes Bake
Ingredients You’ll Need:
For the Dish:
- 4 large russet potatoes (about 2 pounds), peeled and thinly sliced
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 ½ cups whole milk
- 1 cup heavy cream
- 2 cups sharp cheddar cheese, shredded
- 1 cup Gruyère cheese, shredded (optional for extra flavor)
- 2 cloves garlic, minced
- 1 teaspoon salt
- ½ teaspoon black pepper
- ¼ teaspoon ground nutmeg
- Fresh thyme sprigs (for garnish)
- Optional: 1 small onion, finely chopped
How Much Time Will You Need?
This delicious dish takes about 20 minutes of prep time and 1 hour and 10 minutes of baking time. In total, you’re looking at around 1 hour and 30 minutes from start to finish, including resting time for extra creaminess.
Step-by-Step Instructions:
1. Preheat and Prepare:
First, you want to preheat your oven to 375°F (190°C). Grab a 9×13-inch baking dish and grease it lightly with butter or non-stick spray so your potatoes don’t stick later!
2. Slice the Potatoes:
Next, peel and thinly slice your russet potatoes into about 1/8 inch thick rounds. Rinse these slices in cold water to get rid of any excess starch, then drain and pat them dry with a towel. This helps them bake beautifully!
3. Make the Sauce:
In a medium saucepan, melt the butter over medium heat. If you’re using onions, now’s the time to add them. Sauté them until they’re soft, which should take about 3-4 minutes. Then, toss in the minced garlic and cook for another minute, just until it smells amazing!
4. Create a Roux:
Stir in the flour and keep stirring for about 2 minutes—it’ll be a little bubbly and should not brown. This is your roux, and it will help thicken your cheese sauce.
5. Add the Creaminess:
Slowly whisk in the milk and heavy cream until the mixture is smooth. Keep cooking and whisking until the sauce thickens and can coat the back of a spoon. This should take around 6-8 minutes.
6. Cheese It Up:
Take the saucepan off the heat and stir in 1 ½ cups of cheddar cheese along with all the Gruyère cheese (if you’re using it) until it’s melty and smooth. Season your sauce with salt, pepper, and nutmeg, then stir again to mix well.
7. Layer the Potatoes:
In your prepared baking dish, arrange half of the sliced potatoes in an even layer. Pour half of the delicious cheese sauce over this layer, spreading it out evenly.
8. Repeat the Layering:
Now, layer on the remaining potato slices and top it with the rest of your cheese sauce. This makes for two delicious layers of cheesy goodness!
9. Top It Off:
Sprinkle the last ½ cup of cheddar cheese over the top of the dish. This will create a lovely golden crust when it bakes.
10. Bake:
Cover the dish tightly with aluminum foil and pop it in the oven to bake for 45 minutes. This helps the potatoes cook evenly.
11. Finish Baking:
After 45 minutes, carefully remove the foil and let it bake for another 20-25 minutes until the top is golden brown and bubbly, and the potatoes are tender when pierced with a fork.
12. Serve It Up:
Once the baking is done, let the dish rest for 5-10 minutes before serving. This helps everything settle a bit. Garnish with fresh thyme sprigs and enjoy your creamy, cheesy, golden-baked scalloped potatoes!
Can I Use Different Types of Potatoes?
Yes, while russet potatoes are great due to their starchiness, you can also use Yukon Gold potatoes for a creamier texture. They hold their shape well too!
How Do I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, warm gently in the oven or microwave, adding a splash of milk or cream for extra creaminess if needed.
Can I Prepare This Dish in Advance?
Absolutely! You can prepare the potato layers and cheese sauce a day ahead. Assemble everything in the baking dish, cover, and refrigerate. Just add an extra 10-15 minutes to the baking time when you’re ready to cook it.
What Can I Use Instead of Heavy Cream?
If you want a lighter option, you can substitute heavy cream with half-and-half or even whole milk. Keep in mind the sauce may be less rich, but it will still be delicious!
