Potatoes Au Gratin Ingredients
• Discover the perfect blend of flavors!
For the Creamy Base
- Softened Unsalted Butter – Provides richness and helps brown the top; substitute with olive oil for a dairy-free version.
- Russet Potatoes (3 pounds) – Forms the base; ideal for their starchiness providing creamy texture. Avoid waxy red potatoes as they won’t soften properly.
- Heavy Cream (1 cup) – Adds creaminess; can substitute with half-and-half or a non-dairy alternative if desired.
- Minced Garlic (3 cloves) – Offers aromatic depth; can be substituted with garlic powder (1 teaspoon) if fresh is unavailable.
For the Cheesy Layers
- Shredded White Cheddar Cheese (1/2 cup) – Contributes flavor and richness; can replace with sharp cheddar for a deeper taste.
- Grated Parmesan (6 tablespoons) – Enhances flavor and adds a crispy topping; consider using Pecorino Romano for a stronger flavor.
For Seasoning
- Salt and Pepper – Essential for seasoning; adjust to taste and elevate those flavorful Potatoes Au Gratin!
Step‑by‑Step Instructions for Potatoes Au Gratin
Step 1: Preheat and Prepare the Dish
Preheat your oven to 375°F (190°C) and take a moment to grease a baking dish with 2 tablespoons of softened unsalted butter. This initial step is crucial for ensuring a beautiful golden crust on your delicious Potatoes Au Gratin, so don’t skip it! Set the greased dish aside while you work on the ingredients.
Step 2: Slice the Potatoes
Thinly slice your russet potatoes—aim for about 1/8 inch thick—preferably using a mandolin for uniformity. This precision is key to achieving evenly cooked, tender layers throughout your Potatoes Au Gratin. Once sliced, gently place them into a large bowl to prepare for mixing with the creamy goodness.
Step 3: Mix the Creamy Ingredients
In another bowl, combine 1 cup of heavy cream, ½ cup of shredded white cheddar cheese, 4 tablespoons of grated Parmesan, and 3 cloves of minced garlic. Whisk everything together until well blended, then pour this luscious mixture over the sliced potatoes. Toss until every potato slice is fully coated in this rich, creamy layer—your taste buds will thank you!
Step 4: Layer the Potatoes
Carefully layer the coated potato slices upright in the prepared baking dish, stacking them tightly for maximum flavor absorption. Once you’ve arranged the potatoes, pour any remaining cream mixture over the top, ensuring that every slice is beautifully covered. Don’t forget to season generously with salt and pepper to elevate the flavors of your Potatoes Au Gratin.
Step 5: Bake Covered
Dot the surface of the layered potatoes with the remaining butter (about 2 tablespoons), then cover the dish tightly with aluminum foil. Bake in the preheated oven for 35-40 minutes. This covered baking allows the potatoes to steam, ensuring they turn tender and creamy. You’ll know it’s time to unveil them once the aroma fills your kitchen!
Step 6: Bake Uncovered for Crispiness
After the initial baking, carefully remove the foil and sprinkle the remaining 2 tablespoons of grated Parmesan on top. Return the dish to the oven and bake uncovered for an additional 25-30 minutes, or until the potatoes are fork-tender and the top is bubbly and golden. The contrast of the creamy interior with the crispy exterior is what makes Potatoes Au Gratin irresistible.
Step 7: Broil for a Golden Finish
Once the potatoes reach the desired tenderness, switch your oven to broil and let the dish broil on high for just about 1 minute. This quick step will create perfectly golden, bubbly crusts that are a delight to behold. Watch closely to prevent burning—it’s all about that irresistible, crunchy finish!
Step 8: Rest and Serve
After broiling, remove your Potatoes Au Gratin from the oven and let them rest for about 10 minutes before serving. This rest period allows the layers to set, making it easier to cut and serve. The combination of creamy, cheesy layers with a crispy crust will surely impress your family and friends at dinner!

Potatoes Au Gratin Recipe FAQs
What type of potatoes works best for Potatoes Au Gratin?
For the best results, I recommend using russet potatoes. Their starchiness creates a creamy texture that complements the cheesy layers wonderfully. Avoid waxy potatoes like red or fingerling varieties as they won’t soften properly during baking.
How should I store leftover Potatoes Au Gratin?
To store, transfer any leftovers to an airtight container and place them in the refrigerator. They can be safely stored for up to 3 days. I always find they taste better when reheated in the oven to restore their creamy texture.
Can I freeze Potatoes Au Gratin?
Absolutely! To freeze, let your Potatoes Au Gratin cool completely, then transfer them to a well-sealed, freezer-safe container. They can be frozen for up to 2 months. When you’re ready to enjoy them, thaw in the fridge overnight and reheat in the oven at 350°F (175°C) for 20-25 minutes.
What if my Potatoes Au Gratin is too watery?
If you find your dish is too watery after baking, it might be due to using waxy potatoes or not fully coating the slices in the creamy mixture. To remedy this, try adding an extra layer of cheese on top during the last phase of baking or broiling to create a thick crust that absorbs excess moisture.
Can I make Potatoes Au Gratin ahead of time?
Yes! You can assemble your Potatoes Au Gratin up to 24 hours in advance. Just cover it tightly with foil and refrigerate. When you’re ready to bake, remember to add a few extra minutes to the cooking time since it’s going into the oven cold.
Are these Potatoes Au Gratin safe for pets or people with dairy allergies?
As delicious as they are for humans, the ingredients in Potatoes Au Gratin—such as cheese, butter, and cream—are not suitable for pets and can be problematic for those with dairy allergies. If you need a dairy-free alternative, consider using non-dairy cream or cheese substitutes.
