Step‑by‑Step Instructions for Sweet Potato Gratin with Smoked Gouda and Rosemary
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This step ensures that the Sweet Potato Gratin cooks evenly and becomes golden brown. While the oven warms up, gather your ingredients, and prepare your baking dish so that you are ready to assemble shortly.
Step 2: Sauté Aromatics
In a large saucepan over medium heat, melt 4 tablespoons of butter. Once melted, add in 3 cloves of minced garlic and 1 finely diced red onion. Sauté the mixture for about 5 minutes or until the onions are soft and translucent, releasing a wonderful aroma that sets the tone for your gratin.
Step 3: Prepare the Sauce
Sprinkle in 1/4 cup of all-purpose flour and stir continuously for about 1 minute to cook off the raw flour taste. Gradually whisk in 1 cup each of heavy cream and half and half, cooking the mixture for 3 to 4 minutes until it thickens and bubbles gently. Remove the sauce from heat and allow it to cool slightly.
Step 4: Flavor the Sauce
Into the thickened sauce, mix in 1 cup of grated Asiago cheese, 1 tablespoon of freshly chopped rosemary, 1 teaspoon of smoked paprika, 1 teaspoon of ground sage, and a pinch of kosher salt and black pepper. To finish, grate in a touch of freshly grated nutmeg, stirring until all ingredients are well incorporated and the cheese melts into the sauce.
Step 5: Slice the Sweet Potatoes
Peel and thinly slice 2 to 3 medium sweet potatoes to about 1/8-inch thick using a mandoline slicer for even thickness. The sweet potatoes will cook through and become tender during baking, creating the creamy layers essential for a delightful Sweet Potato Gratin.
Step 6: Layer the Sweet Potatoes
Grease a 9″x13″ baking dish with butter. Start layering the sweet potato slices in a circular pattern, slightly overlapping them. This arrangement not only looks appealing but also ensures that each slice is infused with the creamy sauce, enhancing the overall flavor of the gratin.
Step 7: Combine Cheeses with Sauce
Incorporate half of the Colby Jack cheese and half of the smoked Gouda cheese into the cooled sauce, stirring until combined. Pour this creamy mixture evenly over the layered sweet potatoes, ensuring that each slice is covered with the luscious sauce for a rich taste in your Sweet Potato Gratin.
Step 8: Bake the Gratin
Cover the baking dish with aluminum foil and bake in the preheated oven for 45 to 50 minutes. The sweet potatoes should be tender when pierced with a knife. This step helps steam the sweet potatoes, making them perfectly soft before adding that delicious cheesy topping.
Step 9: Golden Topping
After the initial baking time, remove the foil and sprinkle the remaining cheeses on top of the gratin. Bake uncovered for an additional 15 to 20 minutes until the top is golden brown and bubbly. The cheese should be melted and slightly crispy, giving your Sweet Potato Gratin a delightful finish.
Step 10: Rest and Serve
Once done, take the gratin out of the oven and let it rest for 10 to 15 minutes before serving. This resting period allows the flavors to meld together and makes it easier to slice and serve. Your hearty and comforting Sweet Potato Gratin with Smoked Gouda and Rosemary is now ready to delight everyone at the table!

Sweet Potato Gratin with Smoked Gouda and Rosemary Recipe FAQs
How do I choose the right sweet potatoes?
Absolutely! Look for sweet potatoes that have smooth skin and are firm to the touch. Avoid those with dark spots or soft areas, as these may indicate spoilage. A medium size is ideal, as they cook evenly and offer that creamy texture you desire.
What’s the best way to store leftover gratin?
Very good question! Store your leftover Sweet Potato Gratin tightly covered in an airtight container in the fridge for up to 3 days. For optimal reheating, warm it up slowly at a low temperature to maintain its decadent creaminess.
Can I freeze Sweet Potato Gratin?
Definitely! To freeze, let the gratin cool completely, then transfer it to a freezer-safe container or wrap it tightly in aluminum foil. It can be frozen for up to 2 months. When you’re ready to enjoy it, thaw it overnight in the fridge and reheat in the oven at 350°F (175°C) for about 20–25 minutes until thoroughly heated.
What should I do if my gratin comes out too watery?
If your gratin is too watery, it may be due to excess liquid in the sweet potatoes or not cooking the sauce long enough. I recommend using a slotted spoon to drain some of the liquid before serving. Additionally, consider making a roux with more flour and butter, allowing it to thicken before mixing it into the dish.
Is this recipe suitable for my gluten-sensitive friends?
Absolutely! To make your Sweet Potato Gratin gluten-free, simply substitute the all-purpose flour with a gluten-free all-purpose blend or cornstarch. Just be sure to adjust the liquid ingredients slightly, as gluten-free flours can require different ratios for optimal texture.
Can pets safely eat Sweet Potato Gratin?
Keep in mind that while plain sweet potatoes are safe for pets, the creamy sauce and cheese in this dish are not advisable for them. Ingredients like garlic can be harmful to pets, so it’s best to enjoy this delicious gratin yourself and stick to plain, cooked sweet potatoes if you want to share with furry friends!
