Ingredients (serves 4 | makes 1 Lasagne)

  • 1 tbs Coconut oil or extra virgin olive oil
  • 1 Large brown onion, finely diced
  • 2 Garlic cloves, finely diced
  • 1 Medium carrot, grated
  • 1 Medium zucchini, grated
  • 2 cups (250g) Button mushrooms, diced
  • 3 1/4 Cups (800g) Tomato passata or pasta sauce
  • 1/4 Cup Fresh parsley, finely chopped
  • 425g Canned Tuna
  • To Taste Sea Salt + Pepper
  • 6-8 Rice lasagne sheets (or spelt for a non-gluten-free version)
  • 3 tbs Organic, unsalted butter
  • 1/3 Cup (40g) Arrowroot
  • 3 Cups (750ml) Coconut milk or milk of choice
  • 1-1 1/2 Cups (80-120g) Chedder Cheese, Grated
  • To Taste Sea Salt
  • 1 tbs Chia Seeds


  1. Preheat oven to 180C.
  2. Heat oil in a large saucepan and sauté onion and garlic for 2-3 mins or until soft.
  3. Add carrot, zucchini, mushrooms, passata, tuna and parsley and cook, covered, over low heat for approximately 15 mins, stirring occasionally. Season with some sea salt and pepper.
  4. In a medium-sized sauce pan, melt the butter over medium heat.
  5. Add arrowroot and whisk quickly to combine, then add milk, one cup at a time and cook until it thickens, whisking regularly.
  6. Stir in grated cheese, season with sea salt and set aside.
  7. In a medium-sized casserole dish, place the lasagna sheets, then the tomato and tuna mix, then béchamel sauce. Continue layering in this way with rest of the sheets and finish with a layer of béchamel sauce.
  8. Sprinkle chia seeds over the top layer and bake in the oven for 35-40mins.

Notes... Serve immediately, store in the fridge for up to 3 days or freeze for up to 4 months.
Tip: If you want to use fresh fish, simply cook the fish with the onions until browned on both sides, then continue with recipe.

  • Not a fan of this one but thanks for sharing.


  • I’ll be making this for sure, but I know the kids won’t like it so it’ll be just for me and hubby. Perfect because I have to eat gluten free too!
