Ingredients
Yukon Gold Potatoes: These beauties provide a buttery sweetness and creamy texture. Don’t skip out on peeling them—the skins can be a bit tough!
Sweet Potatoes: The star of the show! Their natural sweetness adds a lovely contrast to the Yukon Gold potatoes. Look for firm ones to ensure your gratin holds up beautifully.
Heavy Cream: This is what makes your gratin luxuriously rich! If you’re feeling adventurous, you can swap in half-and-half for a lighter version.
Butter: For that luscious, savory depth. You can use unsalted butter for more control over seasoning.
Fresh Thyme: It brings in a warm earthiness that pairs perfectly with the potatoes. Fresh herbs always elevate a dish!
Salt & Pepper: Essential staples that enhance the flavors and elevate taste. Go for kosher salt and freshly cracked black pepper if you have them!
Grated Cheese (Optional): Adds a wonderful cheesy crust on top! My personal favorite is a sharp cheddar, but feel free to use what you love.

How to Make It
1. Preheat the Oven
Preheat your oven to a cozy 375°F (190°C). This will ensure your gratin bakes evenly to a beautiful golden finish.
2. Peel and Slice Potatoes
Peel and thinly slice both your Yukon Gold and sweet potatoes. Aim for about 1/8-inch thickness so they cook evenly. You can use a mandoline for uniform slices—it’s a handy tool that makes slicing a breeze!
3. Prepare the Cream Mixture
In a saucepan over medium heat, melt the butter, then stir in the heavy cream, fresh thyme, salt, and pepper. Allow this sweet, creamy mixture to warm up, but don’t let it boil! The aroma will make you feel like you’ve stepped into a dreamy culinary oasis.
4. Layer the Potatoes
In a greased baking dish, start layering the sliced potatoes. Alternate between Yukon Gold and sweet potatoes, creating beautiful stripes of yellow and orange. It’s like a work of art!
5. Pour Cream Over Potatoes
Carefully pour the luscious cream mixture over the layered potatoes, ensuring they’re all lovingly coated.
6. Add Cheese Topping
If you’re feeling cheesy (and who isn’t?), sprinkle that grated cheese on top now for added richness and flavor.
7. Cover and Bake
Cover the baking dish with foil and bake for 30 minutes. This initial step helps the potatoes soften and soak up all that creamy goodness.
8. Finish Baking
Remove the foil and bake for an additional 15-20 minutes. Keep an eye on it until the top is golden brown and the potatoes are tender when poked with a fork—heaven!
9. Cool Before Serving
Let the gratin cool slightly before diving in. Trust me; those first bites are worth the wait as the flavors have a moment to set!
Pro Tips for Success
- Consistent Thickness: Aim for even slices for consistent cooking. Uneven slices can lead to some potatoes being mushy while others are still firm.
- Prep Ingredients Ahead: You can peel and slice the potatoes the day before, keeping them submerged in water to prevent browning.
- Experiment with Herbs: Rosemary or sage can be lovely substitutes for thyme if you want to experiment with flavors!
- Don’t Skip the Cheese: For an even creamier layer, consider mixing different types of cheese!
Flavor Variations
- Spice It Up: Add a pinch of cayenne pepper for a spicy kick.
- Swap the Cheese: Try Gruyère or mozzarella for a different flavor profile.
- Nutty Addition: Toss in some toasted walnuts for a wonderful crunch!
Serving Suggestions
Pair this gratin with roasted chicken or a simple green salad for a balanced meal. Beautifully plate the gratin in individual dishes, enjoying not just the delicious flavors but also the lovely colors. A crisp white wine or a fruity apple cider complements the dish perfectly!
Make-Ahead & Storage
You can prepare this gratin a day in advance! Just assemble everything in the baking dish, cover it tightly with foil, and refrigerate. When you’re ready, pop it in the oven and add an extra 10-15 minutes to the bake time. The leftovers can also be kept in the fridge for about 3-5 days.
Leftovers
Transform the leftover gratin into a delicious breakfast hash! Just chop it up and throw it in a skillet with some sautéed onions and scrambled eggs—voilà, a cozy brunch dish!
Freezing
Yes, this dish can be frozen! Allow it to cool completely, then wrap it tightly in plastic wrap and foil. It will last up to 2-3 months in the freezer. To reheat, simply thaw in the fridge overnight before baking.
Reheating
For the best results, reheat your gratin in the oven at 350°F (175°C) until warmed through. This will keep the texture wonderful! You can also use the microwave, but be prepared for a less crispy top.
FAQs
Can I use only one type of potato?
Absolutely! You can use either Yukon Gold or sweet potatoes alone, but the blend is truly magical!
What can I use instead of heavy cream?
If you’re looking for a lighter option, you can substitute half-and-half or a non-dairy milk like coconut milk, though it will alter the flavor slightly.
Can I add proteins to this dish?
Sure! Shredded chicken or cooked sausage can be great additions for a heartier meal.
How do I know when the gratin is done?
The key indicator is tenderness; you can poke the potatoes with a fork. They should be creamy and soft, with a golden crust on top.
