Sweet Potato Gratin Ingredients
For the Gratin
• Sweet Potatoes – The star of the dish; peel and slice into ⅜” rounds for even cooking.
• Butter – Adds richness to the sauce; can be swapped with olive oil for a dairy-free option.
• Garlic – Freshly minced is best for enhancing flavor; it adds a fragrant aroma you won’t want to miss.
• Red Onion – Provides sweetness and depth; yellow onion is a fine substitute if you’re in a pinch.
• All-Purpose Flour – This is your thickening agent; gluten-free flour can work just as well.
• Heavy Cream – Contributes to a rich and creamy texture in the sauce; consider coconut cream for a dairy-free option.
• Half and Half – Adds creaminess; whole milk can replace it if necessary.
• Fresh Rosemary – Infuses herby flavor into the dish; dried rosemary can be used in a pinch, but fresh gives the best flavor.
• Smoked Paprika – Adds a smoky flavor, enhancing the overall taste; regular paprika can be substituted.
• Ground Sage – Offers an earthy note; while optional, it’s recommended to elevate the dish.
• Kosher Salt & Black Pepper – Essential for bringing out the flavors of all ingredients.
• Freshly Grated Nutmeg – Adds a warm, nutty aroma; freshly grated is always preferred for the best flavor.
For the Cheesy Layer
• Asiago Cheese – Provides a sharp flavor; Parmesan can be substituted if desired.
• Smoked Gouda Cheese – This is the main cheese, delivering its creamy smoky goodness; Fontina works as a less smoky alternative.
• Colby Jack Cheese – Adds meltability and creaminess; Mild Cheddar can also do the trick if that’s what you have on hand.
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 initial step ensures that the Sweet Potato Gratin with Smoked Gouda and Rosemary cooks evenly and achieves that delicious golden-brown crust. An oven thermometer can help ensure accuracy for perfect results.
Step 2: Sauté Garlic and Onion
In a large saucepan, melt a generous amount of butter over medium heat. Add freshly minced garlic and finely diced red onion, cooking until the onion becomes soft and translucent, about 5 minutes. This will add depth and aromatic flavor to your gratin.
Step 3: Make the Sauce
Next, sprinkle the all-purpose flour into the saucepan and stir well, cooking for about 1 minute until it forms a roux. Gradually whisk in both heavy cream and half and half, stirring continuously for 3-4 minutes until the mixture thickens slightly and becomes smooth.
Step 4: Mix in the Flavorings
Remove the saucepan from heat and stir in asiago cheese, fresh rosemary, smoked paprika, ground sage, kosher salt, black pepper, and freshly grated nutmeg. Mixing these ingredients will create a flavor-packed sauce for your Sweet Potato Gratin, allowing it to cool slightly as you prepare the potatoes.
Step 5: Prepare the Sweet Potatoes
While the sauce is cooling, peel the sweet potatoes and slice them into ⅜” rounds. Uniform slices are key to ensure even cooking. Arrange your sliced sweet potatoes on a cutting board, taking care to keep them organized for easy layering.
Step 6: Assemble the Gratin
Grease a baking dish with butter, then layer the sliced sweet potatoes in a circular pattern, slightly overlapping each round. This beautiful arrangement will help achieve an even cook. Combine the cooled sauce with half of the Colby Jack and half of the smoked gouda for a creamy topping.
Step 7: Add the Sauce
Pour the cheesy sauce over the arranged sweet potatoes, ensuring every layer is generously covered. Top with the remaining cheeses, creating a rich, gooey layer of melted goodness that complements the sweet potatoes in this gratin marvel.
Step 8: Cover and Bake
Cover the baking dish tightly with foil to retain moisture, then place it in the preheated oven. Bake for 45-50 minutes until the sweet potatoes are tender when pierced with a fork. This step allows the flavors to meld beautifully and the gratin to cook through.
Step 9: Uncover and Brown
After 45-50 minutes, remove the foil and continue baking for an additional 15-20 minutes. Keep an eye on it as it browns; you want it to achieve a delightful golden hue on top. This step ensures your Sweet Potato Gratin with Smoked Gouda and Rosemary has that mouthwatering finish.
Step 10: Rest Before Serving
Once baked to perfection, remove the gratin from the oven and let it rest for 10-15 minutes. This resting period allows the layers to set, making it easier to serve. For an extra touch, consider broiling for a minute to intensify the browning before serving.
