All-in-one lentil lasagne jumble

All-in-one lentil lasagne jumble

A fragrant mix of fried carrot, onion, pepper and garlic is the foundation of this one-pot wonder. All the action unfolds in an ovenproof pan, where you sauté the base with thyme, tomato paste and spinach, then soften lentils and lasagne sheets in the saucy stock. A scatter of parsley and... hey presto!

Before you start

  • 1x large, deep non-stick frying pan with lid

Chop, chop!

  • Heat your oven to 220ºC/fan 200ºC/gas 7.
  • Coarsely grate the carrots, then peel and finely dice the onions. Deseed and finely dice the peppers.
  • Peel and finely chop the garlic, and finely chop the thyme leaves.

Ace the base

  • Spritz a large, deep, ovenproof, non-stick frying pan with cooking spray and put it over a medium heat. Fry the carrots, onions, peppers and garlic for 5-7 mins.

Soften the pasta

  • Add the thyme, tomato paste and spinach. Stir well and cook for 1 min, until the spinach wilts.
  • Add the lentils and their water. Squeeze in the passata, crumble in the stock and pour in 300ml boiled water (400ml for 4 portions). Snap the lasagne sheets into pieces, dropping them into the sauce.
  • Stir, then cover with a lid and simmer for 5-6 mins, until the pasta starts to soften.

Bake your lasagne

  • Remove the lid and put the pan in the oven. Bake for 8-10 mins, until the sauce has thickened and the pasta is cooked.

Finish & serve

  • Finely chop the parsley.
  • Scatter the parsley over the lasagne jumble and serve.
