Keep It FODMAP Friendly
These low FODMAP mashed potatoes are an absolute show-stopper. Check out the notes below for tips on keeping this recipe FODMAP friendly.
First, according to Monash University, potatoes don't have any FODMAPs. This means you can eat as many potatoes as you want without adding to your FODMAP load.
This recipe also uses milk and a type of clarified butter called ghee. If you're in the elimination phase, you'll need to use lactose-free milk. I use high-fat milk for my mashed potatoes because it makes them extra fluffy. For my Canadian peeps, Neilson has a lactose-free line that goes up to 3.25%.
According to the Monash app, butter doesn't have any FODMAPs (because it's all fat). So, you won't need to use lactose-free butter. Traditionally prepared ghee has had all of the milk solids removed during processing, so it's the least likely of any butter to add anything to your FODMAP load.
Just so you know, even though butter (of any kind) doesn't have any FODMAPs, it does have a lot of fat. For some people, fat can cause the smooth muscles in the intestine to spasm. This recipe uses 1/2 a cup of butter, which works out to 1 tbsp of ghee per serving. If you know you are sensitive to fats, you can use 1/4 cup of ghee, instead. The recipe will have a lighter flavour but they'll still taste great.
Last but not least, let's talk about garlic-infused ghee. To perform this feat of magic, we're going to slow roast 3-4 heads of garlic and infuse it in melted ghee.
Talk Nerdy To Me
I know what you're thinking! Garlic is evil and why on earth would I feed it to you? Don't worry, I haven't lost my mind. Keep reading, I'm about to get my nerd on!
The first thing you need to know is that FODMAPs are short-chain carbohydrates bonded together through dehydration synthesis. This means the molecules join together by shedding water (H2O). These bonds are reversible and will break if you re-expose them to water.
This means when you include items like onion and garlic in your recipes, you're unleashing FODMAPs on your food; even if you pull out the pieces you can see.
However, if you cook a FODMAP in fat with low moisture content (like ghee or oil), the bonds will stay intact. This keeps the FODMAP compounds safely inside your food while the fat absorbs the flavour. Just remember to pull out the pieces before you add any other ingredients.
Anytime a recipe calls for both fat and garlic I make an easy swap for garlic-infused oil or ghee. This way I keep the flavour and not the FODMAPs. This method works for onions as well.
Still not sure how you feel about infusing FODMAPs? Monash recently published an article on infusing onions and garlic. You can read their findings here.
Pick Your Headliner
I'm a die-hard meat and potatoes kind of girl, so I generally pair my low FODMAP roasted garlic mashed potatoes with things like turkey, roast beef, or my breaded pork chops. Because they're easy to make in bulk, they're also great for holidays or large family-style meals.

Looking for a show-stopping side? Try these FODMAP friendly roasted garlic mashed potatoes! Perfect for a quiet dinner at home or a large holiday meal.
- 3–4 garlic heads
- 1–2 tbsp olive oil
- 2 bags mini potatoes
- 1/2 cup ghee
- 1.5 cup lactose-free milk, high-fat if you have it
- 1/4 cup green onions – green part only, minced
- 1.5 tsp salt
- 1 tsp pepper
- Preheat oven to 400 degrees. Cut the tips off of the garlic heads and drizzle each head with olive oil. Wrap each head individually with tinfoil and bake for 45-60 minutes – check them at the 40-minute mark and then again every 10 minutes until the center clove is a rich brown colour.
- Bring a large pot of water to a boil and cook mini potatoes for 10 minutes (or until they are tender when pierced with a fork). Drain the water and mash the potatoes roughly with a potato masher.
- Once the garlic heads have cooled, squeeze each garlic clove out of its skin. Melt the ghee in a medium-sized frying pan and add the roasted garlic. Simmer for 8-10 minutes.
- Strain the garlic out of the ghee using a sieve lined with cheesecloth. Squeeze out as much ghee as you can and discard the garlic pieces.
- Add the garlic-infused ghee, green onion, salt, pepper, and 1/4 of the milk and blend with an emersion blender. Add the rest of the milk in small portions until the potatoes have reached the desired consistency. Serve warm.

These look so delicious and creamy! YUM 🙂
Hi, Colleen. Thank you! I can confirm they’re light, fluffy, and absolutely delicious!
Great recipe! Does this mean that I can cook onions and garlic in olive oil and then strain and simply use the oil in say a nice curry or something and I won’t be exposed to the fodmaps? And once I’ve strained the o/g can I then add the infused butter/oil to a dish containing h20 and it won’t be a problem? Game changer
Yes, it is safe to infuse onions and garlic in fats (like oil and butter) as long as you remove all of the pieces. The fat can then be added to anything you want, including dishes that contain water like soups, stir-fries, sauces, etc. You can find out more information about FODMAP water solubility here if you’re interested!
Hope this helps!
