What Are Homemade Au Gratin Potatoes?
Homemade au gratin potatoes consist of thinly sliced potatoes layered with cheese, seasoned with a creamy sauce, and baked to golden perfection. The hallmark of this dish?
Its rich taste and beautiful texture. Au gratin means “to top with cheese and breadcrumbs,” and in our recipe, everything comes together in a wonderfully comforting way.
Why This Recipe Works
- Flavorful Cheese Blend – For my recipe, I use sharp Cheddar, which provides a tangy punch. Combined with a creamy base, the cheese creates a depth that keeps you wanting more.
- Creamy Texture – The combination of milk and butter ensures that every bite is smooth and luscious. This creamy layer makes the potatoes tender while the top crisps up nicely in the oven.
- Layering Technique – By layering the potatoes with seasonings and cheese, each layer mingles beautifully during baking. This method ensures that every forkful holds flavor rather than just potato.
- Versatile Dish – This recipe allows for modifications. Whether it’s adding garlic powder or smoked paprika, you can play around with flavors depending on what you have on hand or your palate preferences.
Ingredients You’ll Need to Make Homemade Au Gratin Potatoes
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- ½ teaspoon sea salt
- Salt and freshly ground black pepper, to taste
- 2 cups whole milk
- 1½ cups shredded sharp Cheddar cheese
- 4 medium russet potatoes, thinly sliced
- 1 medium onion, sliced into rings
- ½ teaspoon garlic powder (optional, for extra savory depth)
- ¼ teaspoon smoked paprika (optional, for a subtle smokey hint)
How to Make These?
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This will ensure that it’s hot and ready when it’s time to bake your masterpiece.
Step 2: Prepare the Sauce
In a medium saucepan over medium heat, melt the butter. Once melted, add the flour and stir continuously to form a roux. Cook it for about a minute, allowing it to bubble but not brown. Gradually whisk in the milk, ensuring no lumps form.
Cook until the mixture thickens—this should take about 5-7 minutes. Stir in salt, pepper, garlic powder, and smoked paprika, if using. Mix in 1 cup of cheese until melted and smooth.
Step 3: Layer the Potatoes and Onion
In a greased baking dish, arrange half of the sliced potatoes, creating an even layer. Add half of the sliced onion on top. Pour half of the cheese sauce over the potatoes and onions. Repeat with the remaining potatoes, onions, and sauce.
Step 4: Add the Topping
Sprinkle the remaining cheese over the final layer. For added texture, some breadcrumbs on the top can create a delightful crunch. However, this step is optional.
Step 5: Bake
Cover the dish with aluminum foil and bake for 45 minutes. After this time, remove the foil and continue baking for another 15-20 minutes. The top should be golden brown and bubbling deliciously.
Step 6: Let It Set
Once out of the oven, let your au gratin potatoes rest for about 10 minutes. This resting time allows the dish to set, making it easier to serve.
Tips for the Best Au Gratin Potatoes
- Choose the Right Potatoes – Russet potatoes are starchy and create the perfect texture in this recipe. Avoid waxy potatoes, as they won’t provide the desired creaminess.
- Slice Evenly – Use a mandoline for uniformly thin slices. This ensures even cooking and consistent texture.
- Experiment with Cheese – While sharp Cheddar is classic, consider adding Gruyère, Gouda, or even a bit of Parmesan for extra flavor.
- Add Fresh Herbs – Sprinkling fresh thyme or chives in the layers can enhance the flavor profile.
- Save Some Cheese for the Top – This way, you’ll achieve a beautifully old-fashioned cheesy crust.
How to Store the Leftovers?
Leftover au gratin potatoes can be placed in an airtight container in the fridge for about 3-4 days. For prolonged freshness, consider freezing them.
When ready to eat, reheat in the oven at 350°F until heated through, or use a microwave for a quicker reheating.
Recommended Side Dishes for Homemade Au Gratin Potatoes
- Steamed Asparagus – The bright, fresh crunch of asparagus contrasts perfectly with the creaminess of the potatoes, providing a vibrant addition.
- Garlic Bread – This savory treat is excellent for scooping up creamy bites and brings a robust flavor to your meal.
- Caesar Salad – Crispy romaine lettuce topped with tangy dressing enhances the richness of the potatoes while adding a refreshing element.
- Stuffed Bell Peppers – For a delightful, colorful side, consider stuffed bell peppers filled with quinoa, veggies, and spices. This balances the heaviness of the potatoes.
Ingredient Substitutions
If you find yourself short on certain ingredients, here are some alternatives:
- Butter – Substitute with olive oil or margarine for a dairy-free option.
- Flour – Use cornstarch or gluten-free flour as a thickening agent.
- Milk – Almond milk or coconut milk work well for a dairy-free version.
- Cheese – Nutritional yeast can be used for a cheesier flavor without dairy. Alternatively, any melting cheese can be substituted.
