Leftover Spag Bol Squares

Use your leftover spaghetti bolognaise to make these delicious squares for an easy to eat lunch box treat.

Many recipes add a cup of grated cheddar cheese. But if you can’t have dairy a clever product called Nutritional Yeast does the trick. Nutritional yeast is full of B vitamins and makes a great cheese replacer thanks to its parmesan like flavour.

Don’t be precious about getting the exact quantities right. If you have more leftover spaghetti bolognaise just add an extra egg. Too easy!

    I think my kids would love this! The freezer is my life-saver when it comes to school lunches, will it freeze?

      Hi Sarah, food safety wise it will be fine, however it may affect the texture once thawed. Ive never tried it personally. I recommend – make them and eat as many fresh and freeze a couple as a tester. Sharon xx

    What is a good alternative to egg for this recipe?

    • Sharon Selby on September 22, 2021 at 4:35 pm

      Hi Alice,
      I havent tried an alternative and this in instance I can’t see one working. My kids will have Spag Bol leftovers for school as these squares or simply reheated and popped in a thermos. You can also check our Egg Replacers guide under Resources / Kitchen Success inside the Allergy Free Club. Sharon xx

    Hi Jeremy,
    Is there any change to the texture?

    • Sharon Selby on January 30, 2022 at 9:01 pm

      Hi Tracey,
      They are a little harder which is a good thing as the slices keep well together but still easy to bite into. They will also soften if reached to room temperature.
      Corn pasta provides the softest leftover pasta. More so than rice or quinoa so you might want to try that first.
      Sharon xx
