In the world of culinary innovation, few techniques have transformed the way we prepare and enjoy food quite like sous vide cooking. This method, which involves vacuum sealing ingredients and cooking them in temperature-controlled water, allows for precision and enhances the flavors of the ingredients. The inspiration for this Sous Vide Chicken with Crispy Sweet Potato and Cheese Gratin emerged from a desire to combine the tender, juicy results of sous vide cooking with the homely comfort of gratins that many of us grew up enjoying. The dichotomy of modern technique against classic comfort is at the heart of this dish, making it an exciting centerpiece for any dinner table.
The sous vide chicken breast serves as the star of this meal, carefully seasoned with salt, black pepper, minced garlic, and finely chopped onions. Cooking the chicken at a consistent 65°C infuses the meat with flavor while ensuring it remains juicy and tender. The secret lies in the simplicity of the seasonings, allowing the natural taste of the chicken to shine while being elevated by the aromatic garlic and onion. This is combined with the sweet potato gratin—a delightful layer of flavors that brings balance to the dish. The gratin is crafted from thinly sliced sweet potatoes, interspersed with a rich cheese blend, preferably Gruyère or cheddar, which melts to form an indulgent, creamy layer. The addition of eggs and heavy cream creates a custardy texture that binds those slices of sweet potato together, making each bite a comforting experience.
To prepare the gratin, the sweet potatoes must be layered with the cheese and seasoned with a pinch of nutmeg—a surprising yet vivid flavor that complements the sweetness of the potatoes beautifully. The method of mixing those ingredients allows for an even coating, ensuring that each slice of sweet potato is infused with that creamy richness. It’s during the baking phase that this dish transforms, as the cheese on top gets wonderfully golden and crispy, offering a delightful contrast to the soft layers below.
Presentation plays a crucial role in this dish. Picture a generous portion of the golden-brown gratin, perfectly layered and shimmering with a crispy top alongside a succulent chicken breast that has been seared to a delectable golden hue. A sprinkle of fresh herbs, whether thyme or parsley, adds a pop of color and freshness, elevating the dish visually and flavor-wise. Arranging the chicken off-center on the plate next to the gratin not only showcases the beautiful textures but also creates an inviting tableau for diners.
When it comes to serving suggestions, consider pairing this dish with a simple green salad drizzled with a light vinaigrette, which will complement the richness of the gratin without overwhelming the flavors of the chicken. A glass of Chardonnay or a light-bodied Pinot Noir can also enhance the experience, providing an elegant balance between the flavors. In essence, this recipe invites you to enjoy the best of both worlds—a modern culinary technique paired with the warmth and comfort of traditional comfort food, making it a perfect choice for a cozy dinner with family or an intimate gathering with friends.

Instructions
-
1.
Prepare the Sous Vide Chicken:
Preheat the sous vide water bath to 65°C. Season the chicken breasts generously with salt, black pepper, minced garlic, and chopped onion. Place the chicken in a vacuum-sealed bag with a drizzle of olive oil. Seal the bag tightly using a vacuum sealer, ensuring no air pockets remain.
Ensure the seal is tight to prevent water from entering. Monitor the temperature of the sous vide bath carefully.
-
2.
Cook the Chicken Sous Vide:
Submerge the sealed chicken bag in the preheated water bath. Cook for 1 hour. During this time, prepare the sweet potato gratin.
Check periodically to ensure the bag remains submerged and water circulating properly around it. Verify that the sous vide machine maintains 65°C throughout the cooking process.
-
3.
Prepare the Sweet Potato Gratin Layers:
While the chicken cooks, prepare the sweet potato gratin. Preheat the oven to 180°C. In a large bowl, combine the thinly sliced sweet potatoes, grated cheese (reserve a little for topping), beaten eggs, heavy cream, salt, black pepper, and a pinch of nutmeg. Mix until evenly coated.
Ensure each sweet potato slice is well coated in the mixture for even cooking and flavor distribution.
-
4.
Layer the Gratin in Baking Dish:
Butter a baking dish and layer half of the sweet potato mixture. Add a layer of the reserved cheese. Then top with the remaining sweet potato mixture. Finish by sprinkling the last of the grated cheese on top. Cover with aluminum foil.
Ensure the layers are even to promote homogeneous cooking. Avoid letting the foil touch the cheese to prevent sticking.
-
5.
Bake the Gratin:
Place the gratin in the preheated oven and bake for about 30 minutes covered with foil. Remove the foil and bake for an additional 10-15 minutes until the top is golden and crispy. The sweet potatoes should be tender when tested with a fork.
Keep an eye on the gratin to avoid over-browning. The internal temperature should reach 95°C to ensure thorough cooking.
-
6.
Finish and Sear the Chicken:
Once the chicken has finished sous vide cooking, remove it from the bag and pat dry with paper towels. Heat a skillet over medium-high heat. Add olive oil and sear the chicken for 1-2 minutes per side until golden brown and has a nice crust.
Do not overcrowd the skillet; sear in batches if needed. Ensure the chicken reaches an internal temperature of 75°C for safe consumption.
-
7.
Serve the Dish:
Plate the chicken alongside a generous portion of the crispy sweet potato gratin. Garnish with fresh herbs if desired and serve hot.
Ensure all components are at a safe temperature before serving.
Tips and Variations
- Substitute chicken with turkey breasts for a leaner option, which will still retain the succulence of sous vide cooking.
- If you're looking for a vegetarian version, you can replace the chicken with firm tofu or tempeh seasoned in the same way, ensuring to maintain the sous vide temperature.
- For the gratin, experiment with different cheeses like fontina or gouda for a unique flavor profile, or try vegan cheese if you're aiming for a dairy-free version.
- Add chopped spinach or kale to the sweet potato layers for added nutrition and color. Simply layer them in with the potatoes.
- Pre-cook the sweet potatoes in boiling water for a few minutes before layering to reduce baking time, ensuring they are tender more quickly.
- For added flavor, infuse the olive oil used in the chicken with herbs such as rosemary or thyme before searing.
- As a special touch, sprinkle some breadcrumbs mixed with a bit of olive oil and herbs on top of the gratin before the final baking to enhance the crispy texture.
- Make the sweet potato gratin ahead of time and refrigerate it uncooked. When ready, simply bake it while you sous vide the chicken for a more streamlined cooking process.
- Serve with a fresh side salad dressed with a light vinaigrette for a well-rounded meal, balancing the richness of the gratin with freshness.
