Potatoes Au Gratin vs. Scalloped Potatoes: What’s the Difference?

At first glance, these two comforting potato dishes might look similar—thinly sliced potatoes baked to perfection in a creamy sauce. But the difference lies in one key ingredient: cheese!

Potatoes Au Gratin

This dish is all about indulgence. Potatoes au gratin, also known as gratin dauphinoise, originates from 18th-century France, where it was first enjoyed as a rustic, hearty meal. The hallmark of this dish is its cheese—a rich addition that elevates the creaminess to a whole new level. Gruyère, Parmesan, or a combination of both are common choices, creating that signature bubbly, golden crust that makes it so irresistible.

In French, “gratin” refers to the browned, crispy crust on top of baked dishes, usually achieved with cheese or breadcrumbs. With potatoes au gratin, it’s all about the cheese, making it the richer and more luxurious cousin in this potato family.

Scalloped Potatoes

On the other hand, scalloped potatoes take a simpler, more traditional approach. This dish typically skips the cheese and focuses on a velvety cream-based sauce made with milk or heavy cream. The name “scalloped” is thought to come from the Old English word collop, meaning thinly sliced.

Scalloped potatoes are usually seasoned with simple flavors like garlic, onion, and herbs, letting the natural sweetness of the potatoes shine. While it may lack the cheesy decadence of au gratin, it makes up for it with a light, homey appeal that pairs well with hearty mains like roast chicken or ham.

How to Tell Them Apart at a Glance

• Potatoes Au Gratin: Includes cheese (often Gruyère or Parmesan), resulting in a richer, more decadent dish with a golden, bubbly top.
• Scalloped Potatoes: Focuses on a cream-based sauce without cheese, offering a simpler, more subtle flavor.

A Timeless French Classic

Potatoes au gratin’s history traces back to the Dauphiné region of southeastern France, where it became a staple dish in the late 1700s. It was often served at grand banquets and later embraced as a comforting side for family meals. Over time, the dish spread across Europe and beyond, adapting to local flavors and ingredients.

Whether you’re team cheese or team cream, both dishes have earned their place at the table. The choice often comes down to the mood—are you craving something rich and indulgent or something simple and classic? Whichever you choose, one thing is certain: when potatoes are involved, you can’t go wrong!

🥔 Choosing the Best Potatoes

Starchy potatoes, like russets, are ideal. Their natural starch helps thicken the sauce and keeps the dish creamy. Plus, they prevent curdling during baking. Avoid waxy varieties as they can remain firm and slippery, instead of melting into the sauce.

🧀 Selecting the Cheese

The cheese you choose sets the tone:

• Gruyère: Melts beautifully with a nutty flavor.
• Parmesan: Adds a sharp, peppery touch.
• Others: Fontina, sharp cheddar, or mozzarella can also work depending on your taste.

For the ultimate flavor, consider blending cheeses (e.g., Gruyère and Parmesan).

🔑 Top Tips for Perfect Potatoes Au Gratin

1. Milk vs. Cream:
   Use a combination of heavy cream and whole milk for the perfect balance of richness and lightness. Avoid skipping heavy cream—it’s essential for that velvety sauce!
2. Peeling Potatoes:
   • Thick-skinned potatoes (like russets): Peel them for uniform texture.
   • Thin-skinned potatoes: Leave the skins on for a rustic feel.
3. Foil Magic:
   Cover your dish with foil during the first part of baking. This traps steam, helping the potatoes cook evenly. Remove the foil toward the end for a crispy, golden cheese topping.
4. Broiling for Color:
   If the top isn’t browning, use the broiler. A few minutes under high heat will give your dish that irresistible golden crust.
5. Avoid Watery Potatoes:
   Lay sliced potatoes on paper towels to absorb excess moisture before layering. Bake uncovered during the last 15–20 minutes to evaporate moisture and achieve a rich, creamy consistency.

🛒 Ingredients

Potatoes & Sauce:

• 6 russet potatoes, cleaned and peeled
• 2 Tbsp. butter, plus extra for greasing

🥄 Directions

Step 1: Prepare Potatoes

Preheat oven to 375°F and grease a 3-quart baking dish with butter. Thinly slice potatoes (1/4-inch thick) and keep them in water to prevent browning.

FAQ Section

1. Can I make potatoes au gratin ahead of time?
Yes! Assemble the dish, cover it tightly, and refrigerate for up to 24 hours before baking. When ready, bake as instructed, but you may need to add a few extra minutes to account for the cold start.

2. Can I make this dish dairy-free?
Absolutely. Substitute heavy cream with a dairy-free alternative like coconut cream or almond milk. Use a plant-based cheese or nutritional yeast for the cheesy flavor.

3. What type of potatoes should I use?
Russet or Yukon Gold potatoes are the best choices. They have a creamy texture and hold their shape well after baking.

4. How can I prevent the cream from curdling?
To avoid curdling, ensure the cream mixture is warm before pouring it over the potatoes. Baking at a consistent, moderate temperature (around 350°F/175°C) also helps.

5. How do I reheat leftovers?
Cover the dish with foil and reheat in the oven at 350°F (175°C) until warmed through, about 20 minutes. You can also use a microwave, but the oven retains the original texture better.

6. Can I add meat to the recipe?
Yes! Thinly sliced ham, crispy bacon, or shredded chicken work well. Layer them between the potatoes for a hearty, protein-packed dish.
