My family loves Shepherd's Pie! It has been one of my favourite dinners since I was a little one (I'm pretty sure I used to eat my weight in it!). It's super easy to make low FODMAP, and FODMAPPED's Red Wine Simmer Sauce & Slow Cooked Chicken Stock make the perfect flavour base. If you don't have access to these products don't fret - you can replace them with 2 cups of my red wine & tomato pasta sauce instead. I suggest pairing the pie with a side of green beans or a simple green salad to make it a balanced meal.
Dairy Free Option: If you need to be dairy free just omit the cheese - it will still be super tasty! Also use a dairy free milk and a dairy free spread.This isn't necessary if you are just on the low FODMAP diet.
Preheat the oven to 200ºC (390ºF). Grease a large oven proof dish.
Garlic infused oil is found in the oil section of your local supermarket. It should be clear with no floating bits of garlic. You can also make garlic infused oil at home by frying garlic cloves in cooking oil, until they are golden and fragrant (then remove the garlic before you continue cooking your meal). This is a low FODMAP way to capture the garlic flavour as the fructans can't leach into the oil.
Make sure you buy a leek that has long green tips (this is the low FODMAP part), as you can’t use the white/light green leek bulb (this part is high FODMAP).
Monash University have tested Worcestershire sauce and it is low FODMAP, despite containing small amounts of onion and garlic. The sauce is low FODMAP because the onion and garlic are fermented during the manufacturing process which reduces the FODMAP levels.
Check the vegan soy based cheese does not include onion, garlic or coconut flour in the ingredients. Cheddar, Colby, mozzarella, and parmesan cheeses are all low FODMAP.
Check your mustard does not contain onion or garlic powder.
Buy a gluten free Worcestershire sauce or substitute 1 tablespoon gluten free soy sauce, 1/4 teaspoon Chinese five spice, and 1/2 tsp brown sugar for every tablespoon of Worcestershire sauce. Often the ingredient labels don't state they are gluten free, so if the ingredients look safe then ring the manufacturer to confirm.
Use a dairy free spread or olive oil spread instead of butter. Butter is considered low FODMAP.
