Torn lasagne with kale & kimchi, plus pickled fennel

September 7, 2025

   

Hetty Lui McKinnon's Tenderheart has been one of our favourite recent additions to the cookbook pile, but we've got to keep reminding ourselves to keep digging through it for more gems (instead of just falling back on the classic gems). This torn lasagne has been on my list for ages, and we had a quiet Sunday night to give it a go. 

The idea of a low fuss lasagne is obviously hugely appealing - no meticulous layering, just a delicious baked melange! There's still a bit of work to prep-wise, but it's definitely easier than some our other baked pasta attempts. There are two pre-baking steps: fry up your kale a bit and then make your smokey tomato sauce and then pile everything up in a baking tray and wait. It was so perfect for my tastes, smokey and spicy and hugely cheesy - the torn lasagne sheets give just enough texture to the whole thing. I would eat it every week if possible. 

We decided it needed some sort of vegetable accompaniment and after a quick flick of Tenderheart I settled on this very basic pickled fennel. It was basically the perfect accompaniment, tangy and crunchy and just the right thing to cut through the rich lasagne. What a meal.

 

   

Torn lasagne with kale & kimchi

(from Hetty Lui McKinnon's Tenderheart)

1 bunch of kale

1 garlic clove, crushed

450g fresh lasagne sheets

500g ricotta

1 cup grated cheddar

1 cup kimchi

olive oil

salt and pepper

tomato sauce

4 garlic cloves, minced

2 tablespoons gochugaru

2 teaspoons smoked paprika

2 teaspoons dried oregano

1 teaspoon white sugar

800g can crushed tomatoes

sea salt

olive oil

Preheat the oven to 200°C.

Trim the leaves off the kale stems and roughly chop them, then finely slice the stems.

Heat some olive oil in a frying pan on high heat and saute the kale stems and garlic for a minute. Add in the leaves, sprinkle generously with salt and pepper and stir-fry for another 4-5 minutes, until the leaves have wilted. Kill the heat and put the kale aside.

Get cracking on the sauce, by heating a couple of tablespoons of olive oil and the garlic in a large saucepan. Cook for 30 seconds and then throw in the gochugaru, paprika, oregano, sugar and a couple of generous pinches of salt. Pour in the crushed tomatoes and about 2 cups of water. Stir everything together and let it simmer for 20 minutes or so. 

Tear the lasagne sheets into rough strips, fairly large ones but really whatever suits your vibe. 

In a large bowl combine the ricotta with a couple of tablespoons of water and whisk until it's smooth. Add half the cheddar, a couple of tablespoons of olive oil and some salt and pepper and stir together. Fold in the kale and the kimchi and then finally gently stir through the torn lasagne sheets.

Pour the sauce into a large baking dish and then gently stir in the cheese/kale/lasagne mix. Top with the rest of the cheddar and carefully pop the whole thing into the oven. Bake for 40 minutes until the cheese has gone nice and golden. Let it all sit for 10 minutes before serving.

Pickled fennel

(from Hetty Lui McKinnon's Tenderheart)

1 bulb fennel, finely shaved and chopped

125ml rice vinegar

2 teaspoons salt

2 tablespoons white sugar

1 teaspoon fennel seeds

1 teaspoon black mustard seeds

Place the fennel in a bowl.

Put 125ml of water into a saucepan and add in the rest of the ingredients. Heat over medium heat until the sugar has dissolved. Take off the heat and immediately pour it over the fennel. Leave to pickle for 15 minutes and serve!
