  • 500 g | 17oz lean beef mince 5% fat
  • 1 tsp salt
  • 1 tbsp granulated sweetener (optional)
  • 2 tsp garlic granules
  • 1/2 tsp smoked paprika
  • 2 tbsp oregano (optional)
  • 680 g | 24oz passata preferably Passata Rustica
  • 400 g | 14oz tin chopped tomatoes crushed tomatoes
  • 3 tbsp tomato paste
  • 250 ml | 1 cup hot beef stock
  • Small piece of Parmesan cheese rind (optional)
  • 2 bay leaves
  • 1 tbsp Worcestershire sauce
  • Large handful fresh basil chopped
  • Salt and pepper to season

White Sauce

  • 1 tbsp low fat spread
  • 2 tbsp plain flour
  • 320 ml | 1 1/3 cups skimmed milk (Healthy Extra)
  • 250 g | 1 cup fat free Quark cheese (free)
  • 200 g | 7oz crumbled feta cheese or use cottage cheese (Healthy Extra)
  • 1 tsp cornflour (cornstarch) diluted in 1 tbsp cold water
  • 2 tsp mustard powder or Dijon mustard
  • 2 tsp garlic granules
  • freshly grated nutmeg (optional)
  • Salt and pepper to season

To assemble

  • 6-8 lasagna sheets use oven-ready lasagna sheets
  • 2 tbsp grated Parmesan
  • 2 tbsp shredded Mozzarella optional
  • black pepper to season

Instructions

  • Spray a large deep sided frying pan or casserole dish with low calorie cooking spray.
  • Add the onions, celery and carrots and cook over medium-low heat for 10 minutes, stirring occasionally. If your pan gets too dry and sticks add a little vegetable stock.
  • Stir in the minced garlic and cook for a couple of minutes.
  • Add the ground beef, breaking it up with the back of a wooden spoon.
  • Brown the mince for a few minutes then add the salt, sweetener, garlic granules, paprika and Italian herb mix.
  • Stir in the tomato paste, passata and chopped tomatoes. Add the Worcestershire sauce, stock, Parmesan rind and bay leaves.
  • Bring to a boil, lower the heat and simmer, partially covered, for 30 minutes, stirring occasionally.
  • Uncover the pan and cook for a further 10 minutes.
  • Check your sauce, it should be thick and rich with most of the liquid absorbed. If it’s still watery you can continue to cook for a little longer. It's important the sauce is as thick as possible.
  • Discard the cheese rind and bay leaves. Stir in plenty of fresh basil and check the seasoning – adjust to your taste if needed.

White Sauce

  • Melt the reduced-fat spread in a large saucepan until it is foaming. Whisk in the flour to make a paste (roux).
  • Add the milk, gradually, whisking constantly, until it is incorporated into the sauce.
  • Lower the heat and stir in the Quark cheese and feta (or cottage cheese).
  • Bring the sauce to a low simmer and add the diluted cornflour. Continue cooking for 3-4 minutes or until it thickens enough to coat the back of a spoon.
  • Stir in mustard, garlic powder and freshly grated nutmeg. Taste the sauce and season with salt and pepper.

Assemble the Lasagne

  • Preheat the oven to 180°C (350°F). Spritz an ovenproof dish measuring at least 30x19cm (10 cup capacity) with low calorie spray such as Fry Light.
  • Add a layer of meat sauce to cover the bottom of the dish and pack it down.
  • Top with a layer of the white sauce - not too much. Cover with the lasagna sheets, breaking them up if necessary.
  • Repeat the process adding another layer of meat sauce followed by white sauce.
  • Top with the final layer of lasagne sheets and remaining white sauce. Sprinkle with the grated Parmesan and shredded mozzarella.
  • Place the lasagna on a shallow baking tray (in case of spillages) and bake for 20 minutes or until the top is golden.
  • Let the lasagna rest and cool for 15 minutes then slice and serve with a green salad or steamed vegetables.

Notes

Tips for the best-ever lasagna

  • Make sure your meat sauce is thick and well seasoned.
  • The white sauce needs to be thick enough to coat the back of a spoon. I have added a little cornflour (cornstarch) to aid this.
  • Make sure you season the white sauce. Taste and add salt and pepper at the end. Feta cheese can be quite salty while cottage cheese is very bland so season accordingly.
  • Leave your lasagna to rest for at least 15 minutes or up to half an hour. This helps the lasagna firm up a little so that is easier to slice. As you will see I was a little too eager when filming the recipe video...
