How to Make the Perfect Sweet Potato Gratin

Creating this culinary masterpiece is easier than you might think! Let’s dive into the ingredients and steps to prepare this delicious Sweet Potato Gratin.

Ingredients

• 3 lbs sweet potatoes- peeled, rinsed, and thinly sliced into 1/8” rounds (mandoline slicer preferred)
• 4 tbsp butter
• 2 cloves garlic, minced or pressed
• 1 small red onion, finely diced
• 1 tbsp all-purpose flour
• 1 cup heavy cream
• 1 cup half and half, or whole milk
• 1/2 tbsp finely chopped fresh rosemary leaves
• 1 tsp smoked paprika
• 1/4 tsp ground sage
• 1/2 tsp Diamond Kosher salt
• 1/4 tsp freshly ground black pepper
• 1/4 tsp freshly grated nutmeg
• 1/3 cup grated asiago cheese
• 1 cup smoked gouda cheese, shredded (divided)
• 1 cup Colby Jack cheese, shredded (divided)

Step-by-Step Instructions

1. Preheat oven to 400 degrees F.
2. Melt butter in a large saucepan over medium heat.
3. Add garlic and onions, and cook stirring occasionally until softened, about 5 minutes.
4. Add the flour and stir well to combine. Cook 1 minute, stirring occasionally.
5. Slowly whisk in the heavy cream and half and half to combine.
6. Bring heat to medium-high and cook 3-4 minutes, stirring occasionally until slightly thickened and starting to bubble. Immediately turn off heat.
7. Stir in asiago cheese, fresh chopped rosemary, smoked paprika, ground sage, salt, pepper, and nutmeg. Remove from heat and allow to cool to room temperature.
8. While your sauce cools, peel potatoes and slice thinly (about 1/8”) with a mandolin slicer or sharp knife.
9. Grease a baking dish with butter or cooking spray, and arrange the potatoes in a circular pattern. (If lying flat, set aside and toss well with prepared sauce before adding to the dish).
10. Once the sauce is fully cooled, stir in half of the Colby Jack cheese and half of the smoked gouda cheese to combine. It will not melt, and that’s ok!
11. Pour sauce over the potatoes in the casserole dish (or stir together with potatoes if lying flat), and top with remaining Colby Jack and smoked gouda cheeses.
12. Cover dish tightly with foil, and bake in the preheated oven for 45-50 minutes, or until potatoes are tender and easily pierced with a pairing knife (it should slide through with no resistance).
13. Once potatoes are tender, remove foil and bake an additional 15-20 minutes, until golden brown. Let rest 10-15 minutes, and serve warm. If you want extra browning, bake a bit longer uncovered or briefly broil if your dish is broiler safe and keep a close eye on it.

For People with Diabetes: Sugar Substitutes

• Consider using stevia, monk fruit, or allulose as sugar substitutes in dishes requiring sweetness.
• Always avoid honey or maple syrup, as they can raise blood sugar levels.

Pro Tips to Elevate Your Sweet Potato Gratin

• Use Fresh Herbs: Fresh rosemary enhances flavor significantly; consider adding thyme for an aromatic touch.
• Layer Wisely: For optimal flavor, alternate layers of sweet potatoes and sauce to ensure that every bite is perfectly cheesy and creamy.
• Let It Rest: Allowing the dish to rest after baking helps the layers to set, making serving easier and enhancing the flavor.

How to Store & Reheat Sweet Potato Gratin

• Fridge: Store leftovers in an airtight container for up to 4 days.
• Freezer: Freeze portions wrapped tightly in plastic and foil for up to 3 months; thaw before reheating.
• Reheat: Gently reheat in the oven at 350°F until warmed through or microwave individual servings with a cover to avoid drying.

Don’ts of Making Sweet Potato Gratin

• Don’t Overcrowd: Ensure the potato slices are even to guarantee even cooking; overcrowding can lead to mushy layers.
• Avoid Cooking Without Precise Heat: Ensure a medium-high setting for creamy consistency; too low and the sauce may separate.
• Skip the Foil Too Soon: Avoid removing the foil too early to prevent drying out the top before the potatoes are fully cooked.
