What are Au Gratin Potatoes?

“Au gratin” is a French culinary term that refers to dishes topped with a browned crust, usually consisting of cheese, breadcrumbs, or both. Potatoes au gratin is made by layering thinly sliced potatoes with a rich, creamy cheese sauce, then baking until bubbly and golden.

Although similar to scalloped potatoes, the key difference is the cheese. Scalloped potatoes usually rely on a milk-based sauce without cheese, while au gratin potatoes take decadence to the next level by incorporating a generous amount of cheese throughout.

Ingredients Needed

To create a delicious pan of au gratin potatoes, you’ll need the following ingredients:

Main Ingredients:

• 4 large Russet or Yukon Gold potatoes (peeled and thinly sliced)
• 2 cups shredded cheese (cheddar, Gruyère, or a mix)
• 2 cups heavy cream (or whole milk)
• 2 tablespoons butter
• 2 tablespoons all-purpose flour
• 2 cloves of garlic (minced)
• 1 teaspoon salt
• ½ teaspoon ground black pepper
• ½ teaspoon paprika (optional)

Optional Additions:

• Cooked and crumbled bacon
• Chopped fresh herbs (chives, parsley)
• Breadcrumbs for topping

Feel free to customize the cheese blend or add extra ingredients like ham or caramelized onions for a unique twist!

Tools and Equipment

To prepare au gratin potatoes, you’ll need the following tools:

• A sharp knife or mandoline slicer (for evenly slicing potatoes)
• Large mixing bowl
• Whisk
• Saucepan
• 9×13-inch baking dish
• Aluminum foil

If you don’t have a mandoline slicer, be extra careful when slicing the potatoes by hand to ensure they are evenly thin, which helps them cook uniformly.

Preparing the Ingredients

Proper preparation is key to a successful dish. Start by washing and peeling your potatoes. Once peeled, slice them thinly—about 1/8 inch thick. Consistency in thickness is crucial for even cooking.

Next, shred your cheese and mince the garlic. If you’re adding any optional ingredients, such as cooked bacon or herbs, have those ready to go.

Pro tip: Soak the sliced potatoes in cold water for a few minutes to remove excess starch. This helps prevent them from sticking together during baking.

Step-by-Step Instructions

Ready to get cooking? Here’s a detailed breakdown of each step:

Step 1: Preheat the Oven

Set your oven to 375°F (190°C). While it’s heating up, grease your baking dish with butter or cooking spray to prevent sticking.

Step 2: Make the Cheese Sauce

In a saucepan, melt the butter over medium heat. Add the minced garlic and sauté for about 30 seconds. Whisk in the flour to create a roux, cooking for another minute until it turns golden. Slowly add the heavy cream, whisking continuously to prevent lumps.

As the sauce thickens, stir in half of the shredded cheese. Season with salt, pepper, and paprika. Once the cheese is fully melted and the sauce is smooth, remove it from heat.

Step 3: Layer the Potatoes

Begin by placing a layer of sliced potatoes in the baking dish. Pour a portion of the cheese sauce over the top, spreading it evenly. Sprinkle some of the remaining cheese over the sauce. Repeat this process until all the potatoes and sauce are used, finishing with a generous cheese topping.

Step 4: Bake the Potatoes

Cover the dish with aluminum foil and bake for 45 minutes. Remove the foil and bake for an additional 20-30 minutes until the top is bubbly and golden brown. Use a fork to test if the potatoes are tender.

Creating the Creamy Cheese Sauce

The secret to a perfect au gratin is a smooth, lump-free cheese sauce. Here are some tips to get it right:

• Use room-temperature ingredients to prevent curdling.
• Whisk constantly when adding cream to the roux.
• Avoid using pre-shredded cheese, as it often contains anti-caking agents that hinder melting.

A well-made sauce should be velvety, rich, and full of cheesy goodness!

Layering and Assembly

Layering your potatoes correctly is essential for even cooking and a perfect blend of flavors. Here’s how to do it:

1. Start with a layer of potatoes: Arrange a single layer of sliced potatoes at the bottom of the baking dish, slightly overlapping the edges like shingles on a roof.
2. Add the cheese sauce: Pour a portion of the prepared cheese sauce over the potatoes, spreading it evenly to coat the entire layer.
3. Sprinkle extra cheese: Add a handful of shredded cheese over the sauce for added richness.
4. Repeat the process: Continue layering potatoes, cheese sauce, and shredded cheese until all ingredients are used. End with a thick layer of cheese on top to ensure a golden crust.

Proper layering guarantees that every bite has the perfect balance of creamy and cheesy flavors.

Baking Time and Temperature

The perfect au gratin potatoes require both time and the right temperature to achieve a tender and flavorful result.

1. Set the oven to 375°F (190°C): This temperature is ideal for evenly cooking the potatoes without burning the cheese topping.
2. Cover with foil: During the first 45 minutes of baking, cover the dish with foil to trap moisture and allow the potatoes to soften.
3. Remove the foil: After 45 minutes, uncover the dish and continue baking for another 20-30 minutes. This allows the cheese to melt and brown, forming a crispy, golden crust.
4. Check for doneness: Insert a fork or knife into the potatoes. If they slide through easily, your dish is ready. If there’s still some resistance, bake for another 10-15 minutes.

Avoid rushing the process, as undercooked potatoes can ruin the texture and taste of the dish.

Tips for a Golden-Brown Crust

A perfectly browned crust is what makes au gratin potatoes so visually and texturally appealing. Here’s how to achieve that irresistible finish:

• Use a high-fat cheese: Cheeses like cheddar and Gruyère melt beautifully and form a golden crust.
• Broil for a few minutes: If your crust isn’t brown enough after baking, switch the oven to broil for 2-3 minutes. Keep a close eye on it to prevent burning.
• Add breadcrumbs: For an extra-crunchy topping, sprinkle breadcrumbs mixed with melted butter and cheese over the top before baking.
• Avoid too much moisture: Excess moisture can prevent browning. Pat your potato slices dry before layering if you soaked them in water.

These simple tricks will give your au gratin potatoes a professional, restaurant-quality finish.

Common Mistakes to Avoid

Even experienced cooks can encounter issues when making au gratin potatoes. Here are a few mistakes to avoid:

1. Slicing potatoes too thick: Thick slices may not cook through, resulting in hard, undercooked potatoes. Aim for slices about 1/8 inch thick.
2. Using the wrong potatoes: Waxy potatoes like red or new potatoes don’t absorb the cheese sauce as well. Stick with starchy varieties like Russet or Yukon Gold.
3. Skipping the foil: Baking without covering the dish initially can dry out the potatoes. Cover with foil for the first part of baking to retain moisture.
4. Not seasoning enough: Potatoes can be bland if not properly seasoned. Don’t forget to season each layer with salt and pepper.
5. Overcooking the cheese sauce: If your sauce is overcooked, it may curdle or separate. Cook it gently over medium heat and whisk constantly.

Avoiding these pitfalls will ensure your au gratin potatoes turn out perfect every time.

Serving Suggestions

Potatoes au gratin is a versatile side dish that pairs well with a variety of main courses. Here are a few ideas:

• Roast chicken or turkey: The creamy, cheesy potatoes complement the savory flavors of roasted poultry.
• Grilled or baked steak: The richness of the dish is a great contrast to the smoky, bold flavors of beef.
• Ham: Au gratin potatoes are a traditional pairing with holiday ham.
• Vegetarian options: Serve with roasted vegetables, a fresh green salad, or a hearty mushroom dish for a complete meal.

For presentation, garnish the dish with chopped chives, parsley, or a sprinkle of paprika for a pop of color.

Recipe Variations

There’s no one-size-fits-all recipe for au gratin potatoes. Here are a few variations to try:

1. Add protein: Incorporate cooked bacon, ham, or shredded chicken between layers for a heartier dish.
2. Experiment with cheese: Try different cheeses like Parmesan, mozzarella, or a blend of Gruyère and fontina. Each cheese adds a unique flavor profile.
3. Use sweet potatoes: Swap regular potatoes for sweet potatoes to create a slightly sweeter, more nutrient-rich version.
4. Incorporate vegetables: Add sautéed onions, garlic, or spinach between layers to boost flavor and nutrition.
5. Spice it up: Add a pinch of cayenne pepper or smoked paprika to the cheese sauce for a subtle kick.

These variations allow you to tailor the dish to your preferences and make it uniquely your own.

Storage and Reheating Tips

If you have leftovers, you’ll want to store and reheat them properly to maintain their delicious taste and texture.

1. Refrigeration: Allow the dish to cool completely before transferring it to an airtight container. Refrigerate for up to 3-4 days.
2. Freezing: You can freeze au gratin potatoes for up to 2 months. Wrap the dish tightly in plastic wrap and aluminum foil to prevent freezer burn.
3. Reheating:
   • For the best results, reheat in the oven at 350°F (175°C) for 20-30 minutes, covered with foil.
   • You can also reheat individual portions in the microwave, though the crust may lose some of its crispiness.

Proper storage and reheating techniques ensure that your leftovers taste just as good as when they were freshly made.
