Ingredients You’ll Need
To create this delicious Homemade Sweet Potato Au Gratin, gather the following ingredients:
- 2 large sweet potatoes, peeled and thinly sliced
- 1 medium onion, thinly sliced
- 2 cups shredded cheese (a mix of sharp cheddar and Gruyère works beautifully)
- 2 tablespoons butter
- 2 tablespoons all-purpose flour
- 2 cups heavy cream
- 1 teaspoon garlic powder
- 1 teaspoon smoked paprika
- Salt and pepper to taste
- Fresh thyme for garnish (optional)
Preparation Steps
Now that you have all your ingredients ready, follow these simple steps to prepare your Homemade Sweet Potato Au Gratin:
Step 1: Preheat Your Oven
Start by preheating your oven to 375°F (190°C). This will ensure that your au gratin cooks evenly and develops a lovely golden brown crust.
Step 2: Prepare the Sweet Potatoes
Using a mandoline slicer or a sharp knife, slice the sweet potatoes into thin rounds, about 1/8 inch thick. This helps them cook evenly and absorb the creamy cheese sauce.
Step 3: Sauté the Onions
In a skillet over medium heat, melt 1 tablespoon of butter. Add the sliced onions and sauté them until they are soft and translucent, about 5-7 minutes. Season with a pinch of salt and pepper. Remove from heat and set aside.
Step 4: Make the Cheese Sauce
In a saucepan, melt the remaining tablespoon of butter over medium heat. Whisk in the flour and cook for about 1 minute to create a roux. Gradually whisk in the heavy cream, stirring constantly to avoid lumps. Bring the mixture to a gentle simmer until it thickens, about 3-5 minutes.
Next, stir in the garlic powder, smoked paprika, and half of the shredded cheese. Mix until the cheese is fully melted and the sauce is creamy. Taste and adjust the seasoning with salt and pepper as desired.
Step 5: Layer the Ingredients
In a greased baking dish, start layering your ingredients. Begin with a layer of sweet potato slices, followed by a layer of sautéed onions, and then a generous drizzle of the cheese sauce. Repeat the layers until all ingredients are used, finishing with a layer of cheese sauce on top.
Step 6: Add the Final Touches
Once you have layered everything, sprinkle the remaining shredded cheese on top. This will create a deliciously cheesy crust as it bakes. For added flavor, you can sprinkle a little extra smoked paprika over the cheese.
Step 7: Bake to Perfection
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 30 minutes, then remove the foil and continue baking for another 15-20 minutes, or until the top is bubbly and golden brown. The sweet potatoes should be fork-tender when done.
