Sweet Potato Gratin Ingredients
Let’s gather what you need to create this delightful Sweet Potato Gratin with Smoked Gouda and Rosemary!
For the Gratin
• Sweet potatoes – 3 lbs – Slice them thin for that perfect melt-in-your-mouth texture.
• Butter – 4 tablespoons – This adds richness to the dish; feel free to substitute with olive oil for a lighter option.
• Garlic – 2 cloves – Fresh garlic elevates the flavors; minced garlic can be used if you’re in a pinch.
• Red onion – 1 small – It caramelizes beautifully, adding a hint of sweetness.
• All-purpose flour – 1 tablespoon – This helps to thicken the creamy sauce for the gratin.
• Heavy cream – 1 cup – For a decadent, creamy base; half-and-half is a great alternative if you want it a bit lighter.
• Half and half – 1 cup – It balances the richness of the heavy cream; you can substitute with whole milk if desired.

• Ground sage – ¼ teaspoon – Its aromatic flavor complements the sweet potatoes perfectly.
• Diamond Kosher salt – ½ teaspoon – A key ingredient to enhance all the flavors; adjust to taste.
• Black pepper – ¼ teaspoon – Freshly cracked offers the best flavor; you can replace it with white pepper for milder heat.
• Nutmeg – ¼ teaspoon – Just a hint adds warmth and complexity to the dish.
For the Cheese Topping
• Asiago cheese – ⅓ cup – Use it for an extra layer of flavor; feel free to skip if you only have Gouda.
• Smoked Gouda cheese – 1 cup shredded – The star of this gratin, bringing that trademark smoky taste!
• Colby Jack cheese – 1 cup shredded – Melts beautifully and adds a touch of creaminess.

How to Make Sweet Potato Gratin
-
Preheat the Oven: Begin by preheating your oven to 400°F (200°C). This step is key for achieving that beautiful golden crust later on.
-
Melt the Butter: In a large saucepan over medium heat, melt 4 tablespoons of butter. Allow it to become slightly bubbly, which adds a richness to your dish.
-
Cook Garlic and Onion: Add 2 cloves of minced garlic and 1 small finely chopped red onion to the melted butter. Cook until softened, about 5 minutes, releasing a lovely aroma.
-
Add Flour: Sprinkle in 1 tablespoon of all-purpose flour, stirring well to combine with the onion and garlic. Cook for 1 minute to eliminate the raw flour taste.
-
Incorporate Creams: Gradually whisk in 1 cup of heavy cream and 1 cup of half and half. Stir until the mixture is smooth and creamy.
-
Thicken the Sauce: Increase the heat to medium-high and cook for 3-4 minutes, stirring occasionally until the sauce thickens slightly. Turn off the heat at this point.
-
Mix in Flavorings: Stir in ⅓ cup of asiago cheese, ½ tablespoon of fresh rosemary leaves, 1 teaspoon of smoked paprika, ¼ teaspoon of ground sage, ½ teaspoon of Kosher salt, ¼ teaspoon of black pepper, and ¼ teaspoon of nutmeg. Let this mixture cool to room temperature.
-
Slice Sweet Potatoes: Peel and thinly slice 3 lbs of sweet potatoes to about ⅛ inches thick using a mandolin slicer or sharp knife for even cooking.
-
Prepare the Baking Dish: Grease a baking dish with butter and arrange the sliced sweet potatoes in a circular pattern, showcasing their vibrant colors.
-
Combine Cheeses: Once the sauce has cooled, stir in half of the 1 cup of Colby Jack cheese and half of the 1 cup of smoked Gouda cheese, blending everything for a delicious layer.
-
Pour Sauce Over Potatoes: Carefully pour the creamy sauce over the arranged sweet potatoes and top with the remaining Colby Jack and smoked Gouda cheeses for that melty finish.
-
Bake Covered: Cover the dish tightly with foil and bake for 45-50 minutes, or until the sweet potatoes are tender and fragrant.
-
Final Baking: Remove the foil and bake for an additional 15-20 minutes until the top is golden brown and bubbling. Allow it to rest for 10-15 minutes before serving warm to let the flavors settle.
Optional: Sprinkle fresh rosemary on top before serving for an aromatic finish.

Sweet Potato Gratin with Smoked Gouda and Rosemary Recipe FAQs
What type of sweet potatoes should I use for the gratin?
For the best texture and flavor, I recommend using medium to large sweet potatoes that are firm and free of dark spots or blemishes. Look for those with smooth skin that feel heavy for their size.
How long does Sweet Potato Gratin last in the fridge?
Your delicious Sweet Potato Gratin can be stored in the fridge for up to 3 days. Just place it in an airtight container once it’s fully cooled to help retain its moisture and flavor.
Can I freeze Sweet Potato Gratin? If so, how?
Absolutely! To freeze, wrap your cooled Sweet Potato Gratin tightly in plastic wrap and then in aluminum foil to protect it from freezer burn. It can be safely stored for up to 3 months. When you’re ready to enjoy it, thaw it overnight in the refrigerator, then reheat at 350°F (175°C) for 20-25 minutes, covered with foil.
What should I do if my gratin is not cooking evenly?
If your gratin is browning too quickly but still not cooked through, cover it again with foil and reduce the oven temperature slightly. This will help cook the potatoes evenly without burning the top. Remember to check for tenderness with a fork—if it’s easily pierced, you’re golden!
Is Sweet Potato Gratin suitable for people with lactose intolerance?
Yes! You can modify this recipe by using lactose-free dairy alternatives like lactose-free milk or cream, and opt for vegan cheese options. This way, you can enjoy the comforting flavors without worry!
Can I use other types of cheese in the gratin?
The more the merrier! While smoked Gouda is a standout, feel free to experiment with other cheeses like sharp cheddar or fontina for unique flavors. Just remember to balance their strengths so they don’t overpower the sweet potatoes!
