Ingredients
To create your Sweet Potato Kale Gratin, gather the following ingredients:
For the Gratin
- 2 large sweet potatoes (about 1.5 lbs or 680 g), peeled and thinly sliced
- 4 cups kale, stems removed and chopped (about 1 bunch)

How to Make Sweet Potato Kale Gratin is a must-try comfort dish!
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). This ensures that your gratin cooks evenly throughout.
Step 2: Prepare Sweet Potatoes
Peel and thinly slice the sweet potatoes using a sharp knife. Aim for consistent thickness to ensure even cooking.
Step 3: Sauté the Kale
Wash and chop the kale. In a skillet over medium heat, add a splash of water or olive oil. Sauté the chopped kale for about 5-7 minutes until it wilts down.
Step 4: Grease Baking Dish
Take your 9×13 inch baking dish and grease it with olive oil to prevent sticking during baking.
Step 5: Layer Ingredients
Begin layering in the baking dish:
1. Place a layer of sweet potato slices at the bottom.
2. Add a layer of sautéed kale.
3. Pour some heavy cream over these layers.
4. Sprinkle grated Gruyère cheese on top.
5. Repeat these layers until all ingredients are used up.
Step 6: Bake the Gratin
Cover the baking dish with aluminum foil and bake in the preheated oven for 30 minutes. Then remove the foil and continue baking for an additional 20-25 minutes until golden brown and tender.
Step 7: Cool Before Serving
Once done, let your Sweet Potato Kale Gratin cool for about 10 minutes before serving. This helps set up the layers beautifully!
How to Serve Sweet Potato Kale Gratin is a must-try comfort dish!
Sweet Potato Kale Gratin is not just a dish; it’s an experience that brings warmth and comfort to any meal. Here are some creative serving suggestions to enhance your dining experience.
With a Simple Green Salad
- A fresh, crisp salad can balance the richness of the gratin. Use mixed greens, cucumbers, and cherry tomatoes with a light vinaigrette.
Paired with Roasted Vegetables
- Roasted carrots, Brussels sprouts, or zucchini add color and extra nutrients to your plate. Simply toss them in olive oil and seasonings before roasting.
With Crusty Bread
- Serve with slices of crusty bread for dipping into the creamy layers of gratin. A warm baguette or sourdough works wonderfully.
Topped with Fresh Herbs
- Enhance the flavor by garnishing with freshly chopped herbs like parsley or chives before serving. This adds freshness and a pop of color.
As a Standalone Dish
- Sweet Potato Kale Gratin can be enjoyed on its own as a hearty main course. The combination of ingredients makes it satisfying enough without any sides.

How to Perfect Sweet Potato Kale Gratin is a must-try comfort dish!
To make your Sweet Potato Kale Gratin even more delightful, consider these tips for perfection.
- Use Fresh Ingredients: Fresh sweet potatoes and kale yield better flavors and textures compared to frozen alternatives.
- Slice Evenly: Ensure that sweet potato slices are uniform for even cooking. A mandoline slicer can help achieve this.
- Experiment with Cheeses: While Gruyère is delicious, feel free to mix in other cheeses like mozzarella or cheddar for additional flavor.
- Adjust Seasoning: Don’t be afraid to taste as you layer. Adjust salt and pepper according to your preference for the best results.
- Let It Rest: Allow the gratin to cool for about 10 minutes after baking. This helps it set and makes serving easier.
- Cover Properly: When baking, ensure it’s tightly covered with foil initially to trap moisture, then uncover for browning.

Common Mistakes to Avoid
When preparing your Sweet Potato Kale Gratin, it’s essential to avoid common pitfalls that can affect the dish’s flavor and texture.
- Boldly slicing sweet potatoes: If your sweet potato slices are too thick, they won’t cook evenly. Aim for thin, even slices for the best results.
- Ignoring seasoning: Failing to season your layers can lead to a bland dish. Don’t forget salt and pepper in every layer for maximum flavor.
- Overcooking the kale: Cooking kale for too long can make it mushy. Sauté just until wilted to retain some texture and vibrant color.
- Not greasing the baking dish: Skipping this step may make it difficult to serve later. Always grease your baking dish with olive oil for easy removal.
- Skipping the resting time: Cutting into the gratin immediately after baking can result in a runny mess. Allowing it to rest helps set the layers properly.
