Ingredients

Here’s what you’ll need to create your Yukon and Sweet Potato Gratin. Remember, quality ingredients yield the best results, so opt for organic or fresh when possible!

Ingredients List:

• 3 tablespoons butter, softened and divided (I love using grass-fed butter for the extra flavor!)
• 2 cups heavy cream (Organic is ideal—trust me, you can taste the difference)
• Coarse salt, to taste
• White pepper, to taste
• 3 garnet yams, peeled and thinly sliced into 1/8-inch rounds
• 4 Yukon gold potatoes, peeled and thinly sliced into 1/8-inch rounds
• 3 teaspoons fresh chopped thyme, divided (substitute with dried thyme in a pinch)
• 1/4 cup panko breadcrumbs (For that delightful crunch!)
• 1/4 cup grated Parmesan cheese (Always choose a block of cheese and grate it yourself for the best flavor)

Prep Notes: Make sure your butter is at room temperature to ensure easy mixing. Slice your potatoes and yams as uniformly as possible for even cooking.

Step-by-Step Instructions

Let’s dive into the hands-on part of this recipe! Preheat your oven, warm up those arm muscles for slicing, and let’s get this gratin started!

1. Preheat your oven to 375°F. This is an essential step for even baking.
2. Grease a 9×9-inch square baking dish with 1 tablespoon of butter. This prevents sticking and adds flavor.
3. Season 2 cups of heavy cream with coarse salt and white pepper to taste—this is where the rich flavor really begins. Divide the cream into two mixing bowls. Toss the 3 peeled and 1/8-inch sliced garnet yams in one bowl and the 4 peeled and 1/8-inch sliced Yukon gold potatoes in the other to coat with cream.
4. Layer those beauties: Slightly overlap the yams in a single layer in the prepared baking dish. Sprinkle with 1 teaspoon of fresh chopped thyme. Next, layer the Yukon gold potatoes on top of the yams, followed by another teaspoon of thyme. Repeat this layering process until the dish is filled just below the top.
5. Pour the cream from the bowls over the top of the dish until it reaches just below the top of the potatoes/yams.
6. Cover tightly with foil and transfer to a rimmed baking sheet (this catches any drips).
7. Bake for 45-60 minutes, until a knife can be inserted easily into the center (the exact time depends on how thinly you’ve sliced your potatoes).
8. Create that tantalizing crust: In a small bowl, melt 2 tablespoons of butter and mix with 1/4 cup of panko breadcrumbs, 1/4 cup of Parmesan, and the final teaspoon of fresh thyme.
9. Remove the foil and sprinkle the breadcrumb mixture evenly over the top. Bake uncovered until the crumbs are golden brown, usually about 10-15 minutes.
10. Rest it: Once out of the oven, let the gratin sit for 10 to 15 minutes. This resting period helps the cream sauce settle and thickens, making it easier to serve.

Chef’s Tip: If you find that the crumbs are browning too quickly, tent your gratin loosely with foil to prevent burning while still allowing it to cook through.

Expert Tips & Tricks

1. Storage: To ensure freshness, cover the gratin tightly with plastic wrap or aluminum foil to keep air out. It will last in the fridge for about 3-4 days; reheat gently in the oven.

2. Make-Ahead: This gratin can be prepared a day in advance; simply layer it in the baking dish, cover tightly, and store it in the refrigerator. On baking day, let it come to room temperature before popping it in the oven.

3. Mix Up Your Ingredients: If you’re looking for a new spin, try adding roasted garlic, caramelized onions, or even a blend of different cheeses like Gruyere or cheddar.

4. Avoiding Soggy Potatoes: Use a mandoline or sharp knife to ensure even slicing. This is crucial to allow all components to cook evenly.

5. Leftover Magic: If you happen to have any leftovers (which is rare!), they make fantastic filling for a potato omelet or even mashed into a creamy soup.
