When kale is in season, it's everywhere - in the shops, at the market, growing abundantly in gardens. And while it's brilliant in salads and smoothies, sometimes you want something a bit more comforting, right? This kale and potato bake is exactly that! It's inspired by classic gratins but made so much simpler. You're boiling potatoes (whole, skins on - easy!), blanching your kale until tender, mixing everything with creamy white sauce, topping with loads of cheese, and grilling until golden and bubbling. The result? Creamy, cheesy, comforting perfection. What I love about this recipe is how versatile it is. I'm using cavolo nero (also called Tuscan kale or black kale) because that's what I had, but regular curly kale works brilliantly too. Even chard or spring greens would be gorgeous! The potatoes give you that lovely starchy comfort, the kale adds beautiful earthiness and nutrients, the white sauce brings everything together with creaminess, and the cheese on top? Well, that's just pure joy when it goes all golden and crispy under the grill. This is perfect for those cold evenings when you want something warming and satisfying. It's great as a main dish for vegetarians, brilliant as a side alongside roast chicken or sausages, and honestly, it's the kind of thing that makes you feel good - both while you're eating it and because you're getting loads of lovely seasonal veg!

Ingredients

For the Bake:

• 4 medium potatoes (about 600-700g total)
• 10 stalks kale or cavolo nero (about 300g prepared weight)
• 500ml white sauce (you can find the recipe here)
• 50g - 100g cheese, grated (cheddar works brilliantly)
• Salt and pepper, to taste
• 1 teaspoon salt (for boiling potatoes)

Instructions

1. Start the potatoes: Place your 4 whole potatoes (skins on, no need to peel!) into a large saucepan. Cover with cold water and add 1 teaspoon of salt. Bring to the boil over high heat, then reduce to a simmer. Cook for 15-25 minutes depending on the size of your potatoes. You want them cooked all the way through - check by inserting a sharp knife into the center. The potato should slide off the knife easily when they're done. 

2. Prep the kale: While the potatoes are cooking, prepare your kale. Remove any really tough stalks (though if you're using cavolo nero, the stalks are usually tender enough to eat). Give the kale a good wash, then slice it up into bite-sized pieces - about 2-3cm wide strips. If the stalks are tender, keep them! They add lovely texture.

3. Boil water for kale: Get another large pot of well-salted water on the boil. This seasons the kale as it cooks.

4. Blanch the kale: Once the water is boiling, add your sliced kale. Boil for 2-3 minutes until the kale is just tender but still has a bit of bite. Cavolo nero might need a bit longer than curly kale, just taste a piece to check.

5. Drain the kale: Drain the kale really well in a colander or sieve. Give it a good shake to get rid of excess water. Set aside.

6. Preheat the grill: Turn your grill (broiler) to high. You want it nice and hot for that golden, bubbling cheese top!

7. Slice the potatoes: Once your potatoes are cooked and cool enough to handle, slice them into rounds about 1cm thick. The skins add lovely texture and nutrients, so leave them on!

8. Mix potatoes and kale: In a large bowl, combine the sliced potatoes and drained kale. Season generously with salt and pepper, taste as you go! Add about a third of your white sauce to the bowl and gently mix everything together. You want the potatoes and kale coated but not drowning in sauce yet.

9. Transfer to baking dish: Tip the potato and kale mixture into a large baking dish, it doesn't have to be perfect!

10. Pour over remaining sauce: Pour the rest of your white sauce over the top, making sure it gets into all the gaps and covers everything nicely. Give the dish a little shake to help the sauce settle in.

11. Top with cheese: Generously grate cheese all over the top. Don't be shy, a good thick layer of cheese is what creates that gorgeous golden, crispy, bubbling top! I use about 50g cheese but just grate it on till it feels like the right amount for you! because honestly, you can never have too much cheese.

12. Grill until golden: Pop the dish under your hot grill and cook for 5-10 minutes, watching carefully, until the cheese is melted, golden, and bubbling away. You want lovely golden-brown spots on top that look absolutely IRRESISTIBLE. Keep an eye on it, grills can be fierce and you don't want it to burn!

13. Serve hot: Remove from the grill and let it sit for just a minute or two (this lets it set slightly so it's easier to serve). Then dig in while it's still hot, bubbling, and at its absolute best!

Chef's Tips

Boil potatoes whole: Cooking them with skins on keeps them from getting waterlogged and adds lovely texture. Plus, the skins are nutritious!

Check potato doneness: A knife should slide easily through the center when they're done. Undercooked potatoes are no fun in a bake!

Salt the kale water well: Well seasoned water seasons the kale as it cooks. 

Drain kale really well: Excess water will make your bake soggy. Give it a really good drain and shake!

Use tender kale stalks: If you're using cavolo nero, the stalks are usually tender enough to eat. Waste not, want not!

Make your own white sauce: It's super easy and tastes SO much better than shop-bought! Click here for the recipe.

Don't skimp on cheese: That generous cheese topping is what makes this dish SO good. Go for it!

Watch the grill: Every grill is different - some are fierce, some are gentle. Keep an eye on it so it doesn't burn!

Serve immediately: This is at its absolute best straight from the grill while the cheese is still bubbling.

Substitutions & Variations

Different greens: Use chard, spring greens, spinach, or even broccoli instead of kale - all delicious!

Add protein: Stir in cooked bacon, ham, or leftover roast chicken for a meaty version

Garlic white sauce: Add 2 cloves minced garlic to your white sauce for extra flavour

Mustard kick: Stir 1 tablespoon Dijon mustard into the white sauce for a tangy twist

Different cheese: Try gruyère, parmesan, or a mix of cheeses for different flavours

Herb it up: Add fresh thyme or rosemary to the potato and kale mixture

Leek addition: Sauté sliced leeks and add them to the mix for extra veg

Crispy breadcrumb topping: Mix breadcrumbs with the cheese for extra crunch on top

Vegan version: Use plant-based milk for the white sauce and vegan cheese on top

Storage & Reheating

Best served fresh: This kale and potato bake is at its absolute best served hot and bubbling straight from the grill!

Refrigerator storage: Store leftovers covered in the fridge for up to 3 days.

Reheating: Reheat in a 180°C oven for 15-20 minutes until heated through. You can add extra cheese on top and grill again for a fresh crispy top!

Microwave option: Individual portions can be microwaved, but the cheese won't be as crispy.

Make ahead: You can assemble the whole dish (without the cheese topping) up to a day ahead. Cover and refrigerate, then add cheese and heat in the oven until hot and then grill when ready to serve.

Freezing: This doesn't freeze brilliantly as potatoes can go a bit grainy when frozen in sauce, but if you must, freeze for up to 2 months and defrost fully before reheating.

Portion leftovers: Great for packed lunches! Portion into containers and reheat at work.

Frequently Asked Questions

Q: Can I use frozen kale? A: Fresh is definitely best for texture, but frozen kale can work in a pinch. Defrost it first and squeeze out ALL the excess water before using.

Q: Do I have to peel the potatoes? A: No! Leaving the skins on is easier, adds texture, and the skins contain lots of nutrients. Just give them a good scrub before cooking.

Q: What if I don't have a grill? A: Bake in a hot oven (200°C) for 20-25 minutes until the cheese is golden and bubbling. 

Q: My kale is quite tough. What should I do? A: Boil it for a bit longer - some kale varieties are tougher than others. It should be tender before you drain it. Or remove the stalks and just use the leaves.

Q: Can I use sweet potatoes instead? A: Absolutely! Sweet potatoes would be delicious - they'll add a lovely sweetness that works beautifully with kale.

Q: Is this suitable for vegetarians? A: Yes! As long as you use vegetarian cheese (some cheeses contain animal rennet), this is completely vegetarian.

Q: How do I make white sauce? A: Check out the recipe on my website! It's super easy - just butter, flour, and milk cooked into a smooth sauce.
