Prepare to discover a side dish that might just become your new obsession: this incredible Sweet Potato and Butternut Squash Gratin. It’s the kind of recipe that makes even the pickiest eaters (myself included!) declare their undying love. In fact, my partner, who has rarely heard me rave about my own culinary creations, confessed this gratin was the first dish she genuinely heard me praise. That’s a testament to how truly exceptional this combination of sweet, savory, and creamy flavors really is. Forget the typical side dish; this gratin elevates any meal to a gourmet experience, making it a perfect addition to your holiday spread or a comforting weeknight treat.
As a home cook who constantly strives for perfection, I scrutinize every single dish before deeming it worthy of sharing. Many recipes go through multiple iterations, tweaked and refined until they meet my high standards. But with this particular gratin, from the very first bite, I knew it was something special. It wasn’t just good; it was extraordinary. I devoured it for lunch for two days straight – a truly rare occurrence for me, as I seldom eat leftovers, especially the same dish. Its undeniable appeal lies in its rich yet balanced profile, promising a delightful culinary journey with every forkful.
What truly sets this gratin apart is its masterful balance. Unlike many gratins that can feel heavy and overwhelmed by cream and cheese, this recipe allows the natural sweetness of the sweet potatoes and the earthy notes of the butternut squash to shine through. You taste the vegetables, not just a dairy-heavy sauce. This thoughtful approach ensures a vibrant and authentic flavor profile that keeps you coming back for more. Furthermore, the choice of Gruyère cheese is simply inspired. Its nutty, slightly sweet, and complex flavor doesn’t just blend; it harmonizes with the other ingredients, creating a cohesive and sophisticated taste that’s hard to pinpoint as a singular component or part of the sauce. It’s this seamless integration of flavors that I find truly captivating.
For me, the absolute best part of this delightful gratin is the magical transformation that happens to the Gruyère cheese, especially around the edges and on the very top layer. As it bakes, it crisps up beautifully, forming a golden, slightly chewy crust that adds an irresistible textural contrast to the soft, tender vegetables beneath. That crispy, caramelized cheese on the sides of the pan? Utter perfection! It’s a detail that might seem small, but it adds an incredible depth of flavor and a delightful crunch that makes each bite an experience to savor. This textural interplay is a highlight that elevates the dish from good to truly unforgettable.
While this sweet potato and butternut squash gratin undeniably shines as a luxurious side dish, it’s far too delicious to be confined to that role. I wholeheartedly encourage you to consider serving it as a light main course, perhaps alongside a fresh, vibrant spring salad. Imagine a warm, comforting plate of this gratin paired with crisp greens – a perfect meal for a cozy evening. This recipe offers a wonderful opportunity to break free from the traditional potato au gratin, introducing a more sophisticated, flavorful, and visually appealing option without sacrificing ease or deliciousness. It’s a delightful upgrade that brings a touch of elegance to any table, whether it’s a holiday feast or a simple family dinner.
Exploring Sweet Potatoes and Butternut Squash: FAQs
Understanding the ingredients in your dishes can enhance your cooking and nutritional awareness. Here are some common questions about sweet potatoes and butternut squash, two stars of our gratin recipe:
Can Sweet Potato Skin Be Eaten?
Absolutely, the skin of a sweet potato is not only edible but also highly nutritious! Many people choose to eat the skin to maximize the health benefits of this root vegetable. When thoroughly washed and cooked, sweet potato skin provides a significant boost of dietary fiber, which is essential for digestive health, and potassium, a vital mineral that supports heart health and fluid balance. The skin also contains various antioxidants, adding another layer of nutritional value. For gratins, if you prefer a smoother texture, you can peel them, but leaving the skin on adds a rustic charm and extra nutrients. Just ensure they are scrubbed clean before slicing and layering.
Do Orange Sweet Potatoes Taste The Same As White Sweet Potatoes?
While both are called “sweet potatoes,” orange and white varieties offer distinct flavor and textural profiles. Orange sweet potatoes, like the popular Beauregard or Jewel varieties, are known for their vibrant color, moist texture, and intensely sweet flavor. They tend to be creamier and more dessert-like when cooked. White sweet potatoes, such as Hannah or Japanese sweet potatoes, have a milder, less sweet flavor and a drier, often starchier texture. They retain their shape well and can have a slightly nutty undertone. For this gratin, orange sweet potatoes typically provide a richer, sweeter counterpoint to the butternut squash, but using a mix or solely white sweet potatoes could offer a more subtle, savory rendition of the dish.
Are Butternut Squash Low Carb?
Butternut squash, while a wonderfully nutritious vegetable, is not considered particularly low in carbohydrates, especially when compared to non-starchy vegetables. A half-cup serving of cooked butternut squash typically contains around 11 grams of carbohydrates. This makes it a moderate-carb option, offering natural sweetness and a good source of vitamins A and C, and fiber. For those following very strict low-carb diets, portion control is key. However, for most healthy eating plans, butternut squash is an excellent addition, providing complex carbohydrates along with a wealth of essential nutrients that contribute to overall well-being. If you are looking for a lower-carb gratin, you might consider swapping some of the squash for zucchini or cauliflower, although the flavor profile would change significantly.

Ingredients
Sauce
- 1 Tub Knorr Homestyle Chicken Stock
- 2 Tablespoons unsalted Butter
- 1 Clove minced Garlic
- 2 heaping Tablespoons Flour
- 4 Ounces Cream Cheese
- 3 Cups Whole Milk
- 1/2 teaspoon Nutmeg
- Salt and Pepper, to taste
Gratin Layers
- 1 Medium Sweet Potato, peeled and thinly sliced
- 1 Small Butternut Squash (2-3 lbs.), peeled and thinly sliced
- Salt and Pepper
- 1 to 1 1/2 Cups Shredded Gruyere Cheese
Note: All measurements are in US Customary units.
Instructions
- In a saucepan over medium heat, combine the Knorr Homestyle Chicken Stock and butter.
- Melt the stock and butter together, then add the minced garlic. Cook for 30-60 seconds, or until the garlic becomes fragrant.
- Quickly whisk in the flour. Continue whisking until the butter mixture clumps together, forming a thick roux.
- Stir the roux for another minute to cook out any raw flour taste.
- Add the cream cheese to the saucepan and continue stirring until the cream cheese is fully melted and incorporated into the mixture.
- As the cream cheese melts, gradually whisk in the whole milk. Continue whisking until the sauce is completely smooth and free of lumps.
- Stir in the nutmeg and approximately 1/2 teaspoon each of salt and pepper.
- Taste the sauce and adjust the seasoning as needed, adding more salt or pepper if desired.
- Allow the sauce to simmer gently for a few minutes until it thickens to your desired consistency.
- Remove the sauce from the heat and set aside.
- Preheat your oven to 375°F (190°C).
- Lightly grease the bottom of an 8×9-inch baking dish.
- Begin layering the sweet potato and butternut squash slices in the prepared baking dish. Arrange them in an alternating pattern (sweet potato, squash, sweet potato, squash) until the bottom of the dish is covered in a single layer.
- Lightly sprinkle the layered vegetables with a pinch of salt and pepper. Drizzle about 1/4 to 1/3 cup of the prepared sauce evenly over the top.
- Sprinkle about 3 tablespoons of shredded Gruyère cheese over the sauce layer. Repeat the layering process: vegetables, salt and pepper, sauce, and cheese. Continue until all the vegetables and sauce are used, ensuring the final layer is a generous topping of Gruyère cheese.
- Bake the gratin in the preheated oven for 45 minutes, or until the vegetables are tender, the sauce is bubbling, and the top is golden brown and crispy.
- Let the gratin rest for a few minutes before serving. Enjoy this comforting and flavorful dish!
Recipe Notes
To store leftovers, cover the baking dish tightly with foil or plastic wrap and refrigerate for up to 3-4 days. Reheat gently in the oven or microwave.

Tips for Perfecting Your Gratin
Achieving gratin perfection involves a few key details. First, ensure your sweet potato and butternut squash slices are uniformly thin, ideally about 1/8 to 1/4 inch thick. This guarantees even cooking and a tender, melt-in-your-mouth texture. A mandoline slicer can be a great tool for this, but a sharp knife and a steady hand work just as well. Second, don’t rush the sauce. Whisking the flour into the butter and cooking it for a minute helps eliminate any raw flour taste, and slowly incorporating the milk ensures a smooth, creamy base without lumps. Finally, while Gruyère is exceptional, feel free to experiment with other cheeses like Parmesan, sharp white cheddar, or a blend for varied flavor profiles. A sprinkle of fresh thyme or sage mixed into the layers can also add an aromatic depth that complements the sweet vegetables beautifully.
Serving Suggestions and Creative Variations
This versatile sweet potato and butternut squash gratin pairs wonderfully with a wide array of main courses. It’s an indispensable side for roasted chicken, turkey, or pork loin, especially during the autumn and winter months. For a vegetarian meal, consider serving it alongside a hearty lentil loaf or a mixed green salad with a light vinaigrette. To add a bit of crunch and extra flavor, try sprinkling a handful of toasted pecans or walnuts over the top during the last 10 minutes of baking. A touch of maple syrup or brown sugar drizzled over the sweet potato layers before adding the sauce can enhance their natural sweetness, creating an even more indulgent dish. For those who enjoy a hint of spice, a pinch of cayenne pepper or smoked paprika in the sauce can introduce a delightful warmth. Don’t be afraid to make this recipe your own!
