Classic Lunchbox Thermomix Zucchini Slice

The Thermomix Zucchini slice is one of my favourite “go to” recipes. It’s packed with healthy zucchini plus the bacon & cheese makes it irresistible.

Whenever I’m looking for a quick, healthy meal to serve I inevitably fall back on this dish.

The recipe ticks all my boxes, it’s delicious, quick to make and everyone always LOVES it! The best part is it includes hidden vegetables, plus the leftovers make a great lunchbox idea. There is always a fight over who gets to take the leftovers to lunch or school.

Zucchini Slice Tip

  1. This recipe freezes well so if you’re one of these super organised mums you could make and freeze the recipe ahead of time.Cut the slice into serving sizes before freezing. The individual portions can be used for school lunches, or single serve dinners on busy nights.

    Unfortunately, I have never been that organised so my tribe fights it out for the measly leftovers.

  2. Note I’ve made the Thermomix zucchini slice in a slice tray and a mini loaf tin. If you do use a loaf tin make sure you line it with baking paper so it doesn’t stick.  You could also make these in large muffin trays with cupcake wrappers. The cooking times will alter depending on what tray you use.

Serving Suggestion

The zucchini slice makes a “figure friendly” main meal when served with a large, fresh salad.
