Use it up tuna, runner bean and kohlrabi lasagna recipe!

I made this lasagna to use up the ingredients I had and to avoid food waste, but it was so good that I will definitely be making it again!  To remind myself and in case any of you guys want to have a go, this is how I did it:
  • Tomato sauce
  • White sauce (you will need to judge the quantities you need of these sauces)
  • 1-2 tins of tuna
  • Dried lasagna sheets (you can substitute for fresh ones, I’m not sure how this would impact on the cooking time though)
  • Several large runner beans chopped into pieces
  • A quarter to half a kohlrabi – sliced
  • Grated cheese
  • A small spoonful of horseradish sauce
  1. Grease a baking dish the right size for your lasagna (I used a glass dish).
  2. Mix the tuna, horseradish sauce and chopped runner beans together with the tomato sauce
  3. Put a sheet of lasagna at the bottom of the dish
  4. Put a layer of tuna and tomato sauce on top of the lasagna sheet
  5. Next add a layer of thinly sliced kohlrabi (if you don’t have kohlrabi to slice up you can replace it with whatever you like e.g. squash, turnip or aubergine…)
  6. Next add a layer of white sauce
  7. Optional: grate over some cheese
  8. Add another layer of lasagna and repeat until you have run out of space.
  9. Finish off with a layer of lasagna topped with white sauce and then cover with grated cheese
  10. Bake in the oven for one hour at 180 degrees C.  Keep an eye on it as you may want to turn the heat down a little and/ or cover the lasagna after around half an hour to prevent it from burning.  You could probably also cook it for a shorter time if you are in a hurry.
Once ready serve hot and enjoy!  I added some peas on the side (after the picture was taken), but any vegetables or salad on the side would work perfectly.

  1. How did the kohlrabi work out? I sometimes see in the supermarket & contemplate giving it a go. It appears to be somewhat exotic for North Yorkshire palates, so often ends up on the bargain shelf!

    I like it! It tastes a bit like a turnip. You can do loads of things with it e.g. bake, roast, stew, slice up thinly and stir fry it or turn it into soup. I think it is worth giving a go!
