Ingredients

  • 1 package gluten free lasagna sheets I used Barilla
  • 14 oz | 400g grated mozzarella cheese

Bolognese sauce

  • 32 oz | 900g minced meat beef, pork/beef or chicken
  • Drizzle of olive oil or garlic infused olive oil
  • 14 oz | 400g canned tomatoes diced
  • 1 carrot diced
  • 1 cup | 240ml water
  • 2 tsp dry oregano
  • Salt to taste
  • 1/2 cup fresh parsley chopped

Bechamel sauce

  • 2 tbsp butter
  • 2 tbsp cornstarch
  • 1 cup | 240ml lactose free milk
  • 1/2 tsp salt

Instructions

Bolognese sauce

  • In a pan, heat the oil over medium-high heat. Add the canned tomato and cook for 2 minutes. Then add the minced meat, put the lid on and cook over medium-high heat for 5 minutes, stirring occasionally.
  • Add water and carrots and bring to a boil. Reduce the heat to low, add the oregano, parsley and season with salt. Cook with the lid on for 40 minutes.

Béchamel sauce

  • Melt the butter in a small pan over low heat. Add the cornstarch and stir until you get a homogeneous consistency. Cook for 1 minute, until it thickens.
  • Slowly add the milk and stir non-stop for 5-10 minutes, until you get a creamy texture. Season with salt.

For assembly

  • In a large ovenproof dish, start by covering the bottom with lasagna sheets moistened with warm running water (so they soften a little).
  • Spread a generous amount of bolognese sauce on top and repeat the process until you run out of lasagna sheets.
  • Cover the lasagna with the béchamel sauce and place the grated mozzarella cheese on top.
  • Bake in a preheated oven at 390ºF | 200ºC for 30 minutes or until browned to taste.

Notes

Safe amounts on the low FODMAP diet
  • Canned tomatoes are limited to 100g per meal, more will have too much fructose. The recipe calls for 4 times more but it's for 9.
  • Mozzarella cheese is low FODMAP. The recommended amount is 1.41oz | 40g, but you can eat more as you will have to exceed 4 cups | 630g to have moderate amounts of lactose.
  • Butter is low FODMAP, as it has only trace amounts of lactose. Some people, however, may be sensitive to fat, which can affect intestinal motility. The recipe calls for only 2 tablespoons for 9 servings, and should not cause symptoms.
Safe low FODMAP serving size You can eat up to 1/4 of the lasagna, a bit more than two portions per meal.
