These IBS-friendly mashed potatoes are fluffy, rich, and super satisfying—without upsetting your stomach. Made with lactose-free milk or almond milk and real butter, they have all the comfort of classic mashed potatoes but none of the high-FODMAP triggers. You can mash them by hand or with a mixer in just 25 minutes.
Ingredients Needed:
- 2 to 2.25 pounds Yukon Gold potatoes: creamy texture, FODMAP-safe.
- ¾ cup unsweetened almond milk or lactose-free milk: smooth and gentle.
- 4 Tbsp unsalted butter: rich flavor without FODMAPs.
- ½ tsp salt: optional, adds basic flavor.
- Optional toppings: extra butter, snipped chives, black pepper, or plain ground horseradish.
How to Make Low FODMAP Mashed Potatoes:
Prep Potatoes:
Scrub the potatoes well. Peel them for a smoother mash, or leave the skins on for extra fiber. Cut into 1½ to 2-inch chunks.
Boil Potatoes:
Bring a large pot of water to a boil. Add the chopped potatoes and cook for 10–15 minutes, or until fork-tender.
Mash with Mixer (Optional):
Drain and transfer potatoes to a stand mixer. Add milk and butter. Use a low-speed setting (like 2) and mix for 30–60 seconds, until just mashed. Avoid over-mixing—they’ll turn gluey.
Mash by Hand:
Drain and return potatoes to the pot. Add milk and butter. Use a potato masher to reach your desired texture.
Adjust & Serve:
Taste and add salt. Add a splash more milk if too dry. Serve warm with your favorite tummy-friendly toppings.

Recipe Tips:
- Avoid over-mixing—mashed potatoes can turn gummy.
- Peel the potatoes if you want a smoother, bloat-free mash.
- Try horseradish or chives for gentle, onion-like flavor without FODMAPs.
- Use Monash-certified almond or lactose-free milk for best results.
How to Store & Reheat:
- Room Temperature: Serve immediately; don’t leave out over 2 hours.
- Fridge: Store in an airtight container up to 3 days.
- Freezer: Freeze up to 1 month in portioned containers. Reheat gently with a splash of almond or lactose-free milk.
