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 is crucial for achieving perfectly cooked layers of sweet potato and kale.
Step 2: Prepare Sweet Potatoes
Peel and thinly slice the sweet potatoes using a sharp knife. Make sure the slices are uniform in thickness for 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 becomes wilted.
Step 4: Grease the Baking Dish
Using olive oil, grease a 9×13 inch baking dish. This prevents sticking and helps achieve a nice crust on the gratin.
Step 5: Layer Ingredients
In the greased baking dish:
1. Start with a layer of sweet potato slices.
2. Add a layer of sautéed kale.
3. Pour some heavy cream over this layer.
4. Sprinkle grated Gruyère cheese on top.
5. Repeat layers until all ingredients are used up.
Step 6: Bake Covered
Cover the baking dish with aluminum foil.
Bake in the preheated oven for 30 minutes.
Step 7: Finish Baking Uncovered
Remove the foil from the baking dish:
Bake for an additional 20-25 minutes until golden brown on top and tender when pierced with a fork.
Step 8: Cool Before Serving
Let cool for about 10 minutes before serving to allow flavors to meld together beautifully.

Common Mistakes to Avoid
When preparing your Sweet Potato Kale Gratin, it’s important to avoid common pitfalls that can affect the dish’s flavor and texture.
- Overcooking the kale: Sautéing kale for too long can make it mushy. Aim for just 5-7 minutes until it wilts, preserving its vibrant color and texture.
- Inconsistent sweet potato slices: Unevenly sliced sweet potatoes can cook unevenly. Use a mandoline or sharp knife to achieve uniform thin slices for optimal cooking.
- Skipping seasoning: Forgetting to season each layer can lead to bland flavors. Season the kale and cream mixture well, and add salt and pepper between layers.
- Not covering while baking: Leaving the dish uncovered at the start can cause it to dry out. Cover with aluminum foil during the first half of baking to retain moisture.
- Not letting it cool before serving: Serving immediately may result in a runny gratin. Allow it to cool for 10 minutes to set properly before slicing.
