This is just my new favorite kale recipe - a kale potato casserole. With a good amount of kale mixed with the mashed potatoes and sun-dried tomatoes. It's flavorful, cheesy comfort food, great when you're in need of some extra vitamins! This casserole dish is easy to prepare on the forehand, so you only have to bake the dish when ready to eat.

A comfort food kale recipe
Kale is one of the most nutritious plant foods. And this casserole is a great way to prepare it in a different way (instead of the usual salad). It's a mash made with potatoes and flavored with soy sauce, sun-dried tomatoes, and cheese.
This is put in a casserole dish and sprinkled with grated cheese. And when baked in the oven for just 20 minutes a delicious potato kale gratin is the end result! You'll love it!

- Kale: 1 pound of kale is used. Slice it in thin strips of about ¼ inches (½ cm) thick. Then wash your kale.
- Potatoes: use 2 ½ pounds of baking potatoes. They're the best for preparing a mash. You peel the potatoes and then cut them so they're about the same size (that way they're all done at the same time). Wash them thoroughly.
- Sun-dried tomatoes: for this recipe, I like semi sun-dried tomatoes best because they're moist. But you can use canned sun-dried tomatoes instead.
- Sweet soy sauce: a surprising ingredient that adds a delicious flavor to the mash.
- Cheese: Cheese is used to flavor the mash and to top the casserole so you can gratin it. I prefer Gouda cheese, but you can substitute it with cheddar or Emmentaler.
🔪 How to prepare a kale potato casserole

Step 1 Boil potatoes and kale until they're done. Add 4 inches (10 cm) of water to a pan and add the potatoes and kale. Bring to a boil and cook for 20 minutes until the potatoes are done.
You can check if your potatoes are done by pricking with a fork into the potato. When it slides in smoothly they are ready. Drain the potatoes and kale and put everything back into the pan.

Step 2 Mash the potatoes with kale. With a potato masher mash the potatoes with the kale. Then stir everything through. By this time you can add a lump of butter if you like (the casserole will become more creamy), but it's not necessary.

Step 3 Add the flavoring. Add 3 oz. (75 grams) cheese cubes, sun-dried tomatoes, and sweet soy sauce to the mash and give everything a stir. Because the cheese melt it will blend through the mash.

Step 4 Put the mash in the casserole dish and sprinkle 2 oz. (50 grams) grated cheese on top. Bake that for 20 minutes in the oven so you've got a kale potato gratin. Serve immediately.
- For the cheese you can use Gouda, Gruyere, Emmentaler or Cheddar. Use freshly grated cheese if you can. It tastes better, because it doesn't contain anti caking agents, which can give a slightly powdery feel.
- You can add 2 tablespoons of butter to the mash for a smooth and creamy feeling. (that isn't necessary though). You could also use 1 tablespoon of olive oil if you prefer that.
- If you want to make this dish vegan, substitute the cheese with vegan cheese.
- By mashing the kale-potato mixture use a masher and not an electric mixer. The electric mixer will give a glue texture to the mash (which isn't a delicious feeling).
