Sweet leek, ricotta & tomato lasagne

Leek Lasagne

Serves 6

  • olive oil

  • 4 leeks, thinly sliced

  • 2 red onions, thinly sliced

  • 250 g spinach, washed and chopped

  • 350 g good-quality ricotta

  • 1 litre base tomato sauce

  • 1 packet lasagne sheets, wholewheat if you can find them

  • 125 g mozzarella ball

  • 75 g fresh Parmesan, grated

  • sea salt

  • freshly ground black pepper

Preheat your oven to 180ºC/350ºF/gas 4. Heat a large saucepan and add a splash of olive oil. Add the leeks and sliced red onions, and sweat, slowly, until soft – about 10 minutes. Add the chopped spinach and briefly cook until wilted down. Set aside to cool slightly, then drain off any excess liquid in the pan.



Mix the ricotta into the leek and onion mixture and season with a tiny pinch of salt and pepper.



Spoon a quarter of the base tomato sauce into the bottom of 6 individual ovenproof dishes, or into a 3-litre ovenproof dish. Cover with sheets of lasagne. Spread half the leek and ricotta mixture over the lasagne, then add a third of the remaining tomato sauce. Repeat with more lasagne sheets, the remaining leek and ricotta mixture and then half the remaining tomato sauce. Finish with a final layer of lasagne sheets, then spread the rest of the tomato sauce over the top.



Tear the mozzarella into small pieces and dot over the top of the lasagne. Sprinkle with the Parmesan. Place on a baking sheet and bake the individual lasagnes for 25–30 minutes or the large one for 45 minutes – they need to be cooked through and golden brown on top.

Calories

Calories are just a unit of energy. If you eat more than you use you can gain weight, or lose it if you don't eat enough. How much you need depends on your weight, gender and how active you are, but it's around 2,000 a day.

Carbs

Carbs are a great source of energy and, excluding foods such as potatoes, are made from grains - like bread, pasta and cereal. We all need carbs, but try to make them all wholegrain by sticking to brown bread, rice and pasta - they are much more nutritious.

Sugar

We all deserve a treat sometimes, but try to limit your sugar intake. Most of your sugar should come from raw fruit and milk, because they give us lots of nutrients too. Always check food labels so you know how much sugar you're eating.

Fat

We all need to eat a small amount of fat because it protects our organs and helps us grow. But we need to be careful about how much fat we eat and what kinds of fat, because in higher levels it's associated with weight gain, diabetes, cancer and heart disease.

Saturates

Saturated or "bad fats" are in beef, pork, chicken skin, butter, cream and cheese. Too much can be bad for our heart and cholesterol levels, but unsaturated or "good fats" in fish, nuts, avocados and some oils can help keep our hearts healthy if eaten in moderation.

Protein

Protein helps our muscles to grow and repair, as well as providing you with essential amino acids. When it comes to protein, try to eat leaner sources such as chicken and fish or non-meat sources such as eggs, dairy, beans, nuts, seeds, tofu and pulses.

BUYING SUSTAINABLY SOURCED FISH

Close

Buying sustainably sourced fish means buying fish that has been caught without endangering the levels of fish stocks and with the protection of the environment in mind. Wild fish caught in areas where stocks are plentiful are sustainably sourced, as are farmed fish that are reared on farms proven to cause no harm to surrounding seas and shores.

When buying either wild or farmed fish, ask whether it is sustainably sourced. If you're unable to obtain this information, don't be afraid to shop elsewhere – only by shopping sustainably can we be sure that the fantastic selection of fish we enjoy today will be around for future generations.
