Low FODMAP Pantry Staples: What to Buy First

Michael Eisenwasser 8 min read

A pantry is the difference between cooking low-FODMAP meals on a Tuesday night and ordering takeout because everything in the fridge needs a sauce you don't have. Fresh produce and proteins rotate weekly; the pantry is the quiet infrastructure that makes the diet repeatable.

This is the pantry companion to the week-one low-FODMAP grocery list. That list is what you buy fresh every few days. This list is what you stock once and keep topped up. Build this pantry the week before you start the elimination phase and you'll stop hitting the "I can't make anything" wall that derails most first attempts.

Oils

Oils are the easiest category on the diet. FODMAPs are water-soluble carbs, and oil is fat, so pure oil contains no FODMAPs.

Stock these:

• Garlic-infused olive oil. The workhorse of every savory meal. Fructans don't dissolve in oil, so you get the flavor without the FODMAP load, provided there are no solids in the bottle. A shelf-stable Monash-certified brand is the simplest option. If you make your own, strain the garlic out, refrigerate, and use within a few days (garlic in oil at room temperature is a botulism risk). Hub recipe coming shortly on the recipes page. More on the mechanism in is garlic low FODMAP.
• Extra-virgin olive oil. For roasting, sautéing, and dressings. No FODMAPs, no serving limit.
• Neutral cooking oil. Canola, sunflower, grapeseed, or avocado oil for anything that needs a higher smoke point.
• Sesame oil. A small drizzle replaces a lot of the "something missing" feeling in stir-fries when you can't use onion.
• Butter and ghee. Butter is almost pure fat with trace lactose, low FODMAP at a standard serve. Ghee is clarified and effectively lactose-free.

Skip any "garlic oil" with visible chunks at the bottom. Those are fructan-loaded solids sitting in the oil you're about to pour on your food.

Vinegars

Most vinegars are low FODMAP at normal cooking serves. Monash tests them because fermenting fruit or grain can leave residual sugars.

Stock these:

• White vinegar, rice vinegar, red wine vinegar, white wine vinegar, apple cider vinegar. All low FODMAP at standard cooking serves. Check the Monash app for the exact cutoff if you're using it in larger amounts.
• Balsamic vinegar. Low FODMAP at a small drizzle; Monash flags it higher at larger serves. Fine on a salad, not for a cup-sized reduction.

Olive oil, red wine vinegar, salt, and Dijon is the default dressing. Most bottled dressings go on the shelf because of onion and garlic.

Salt, pepper, and single-note spices

Almost every single-ingredient dried spice is low FODMAP at cooking serves. Monash has tested the common ones and the list is long.

Stock these: salt, black pepper, white pepper, paprika, smoked paprika, cumin, coriander, turmeric, ginger powder, cinnamon, nutmeg, cardamom, cloves, allspice, chili powder (check the label; see below), cayenne, mustard powder, star anise, fennel seed, dried oregano, dried basil, dried thyme, dried rosemary, dried sage, dried tarragon, dried dill, bay leaves, saffron.

Leave on the shelf: garlic powder, onion powder, and any blend that lists either. That rules out most supermarket taco, ranch, "everything bagel," poultry, garam masala, and curry powder formulations. Italian seasoning varies; some brands are just herbs, some add garlic or onion. Read the label.

The trap word is "chili powder." Many US supermarket chili powders are blends that include garlic and onion, not just dried chili. If the label says only "chili" or a single pepper name, you're fine. If the first few ingredients are garlic, onion, cumin, oregano, you're buying a taco kit.

Rule of thumb: single-ingredient jars are the safe default. For a blend, check the label; if garlic, onion, inulin, or "natural flavors" appear, leave it.

Dried grains

The grain aisle is where most of the calories in an elimination pantry live.

Stock these:

• White rice, brown rice, basmati, jasmine. All low FODMAP at a standard cooked serve. Rice is the most reliable base on the diet.
• Quinoa. Low FODMAP at a standard cooked serve. Complete protein, so it doubles as a vegetarian entree base.
• Gluten-free rolled oats or standard rolled oats. Low FODMAP at roughly 1/2 cup dry. "Gluten-free" oats are just oats certified free of wheat cross-contact; they're no lower in FODMAPs than regular oats, but they matter if you also react to gluten.
• Polenta and cornmeal. Low FODMAP at a standard serve; a quick side dish base when you're tired of rice.
• Rice noodles and 100% buckwheat noodles (soba). Read the soba label; many brands cut buckwheat with wheat flour.
• Millet, amaranth, teff. Low FODMAP at Monash's listed serves. Check the app for exact portions if you want to rotate beyond rice and quinoa.

Skip wheat pasta, couscous, semolina, bulgur, farro, rye, and barley. Skip boxed "rice pilaf" or "quinoa blend" products; they season with onion and garlic powder.

Canned goods

Canned foods carry a rinsing rule most people miss. With legumes, the fermentable carbs leach into the canning liquid; draining and rinsing removes a meaningful fraction.

Stock these:

• Canned chickpeas, drained and rinsed. Low FODMAP at a small rinsed serve (roughly 1/4 cup). A salad topping or a scoop in a grain bowl. Dried chickpeas cooked from scratch are a higher Monash entry.
• Canned lentils, drained and rinsed. Low FODMAP at a small rinsed serve. Skipping the rinse undoes the serve.
• Canned tomatoes and passata. Low FODMAP at small serves; check Monash for the current per-product threshold.
• Tomato paste. Low FODMAP at around 2 tablespoons.
• Canned tuna and salmon in spring water or olive oil. Plain canned fish is naturally FODMAP-free. Skip anything "in sauce."
• Canned coconut milk. Low FODMAP at a small serve; Monash has separate entries for canned, carton, light, and regular, so confirm for your brand.
• Olives. Green and black are low FODMAP at Monash's listed serve.

Skip canned baked beans (onion, garlic, often HFCS), canned soups, and canned pasta sauces unless they're Monash-certified.

Baking staples

Baking on low FODMAP is easier than it looks once the pantry is set up. The trick is replacing wheat flour and sorting out which sweeteners pass.

Stock these:

• Gluten-free flour blend. Look for blends based on rice, potato, tapioca, and corn starch. Skip blends with chickpea, soy, lupin, or coconut flour as a main ingredient (all high FODMAP in baking quantities). Bob's Red Mill 1-to-1 is a common low-FODMAP-friendly blend in the US; check the label, formulations change.
• Almond flour, small amounts. Low FODMAP at a small serve (around 1/4 cup). Fine as part of a recipe, not as the entire base of a loaf.
• Maple syrup. Low FODMAP at 2 tablespoons. Default liquid sweetener for baking and dressings.
• Table sugar (sucrose). Low FODMAP at standard serves. Brown sugar too.
• Dextrose (pure glucose). Low FODMAP in unrestricted serves, a monosaccharide absorbed without issue. Useful for recipes that need a non-sweet-tasting sugar.
• Baking soda, baking powder, cream of tartar, yeast. All FODMAP-free.
• Cornstarch, arrowroot, tapioca starch, potato starch. All low FODMAP; use for thickening.
• Cocoa powder (unsweetened). Low FODMAP at Monash's listed serve; higher amounts are a separate entry.
• Vanilla extract. Low FODMAP at 1 teaspoon.

Skip honey, agave, HFCS, and any sugar alcohol ending in "-ol" except erythritol (sorbitol, mannitol, xylitol, and maltitol all trigger polyol symptoms). See low-FODMAP sweeteners for the full rundown.

Condiments

Condiments are the category that catches people most often, because the onion and garlic hide in bottles of things that "feel" simple.

Stock these:

• Plain yellow mustard, Dijon mustard. Low FODMAP at a tablespoon. Skip "honey mustard."
• Mayonnaise. Low FODMAP at 2 tablespoons. Standard mayo is just egg, oil, vinegar, salt, lemon. Skip "garlic aioli."
• Ketchup. Low FODMAP at a small serve (around 1 sachet / 1 tablespoon). A tablespoon on a burger is fine; a half cup on fries isn't.
• Soy sauce and tamari. Low FODMAP at 2 tablespoons. Tamari if you want gluten-free.
• Fish sauce. Low FODMAP at a tablespoon. Huge flavor leverage when you can't use onion or garlic.
• Worcestershire sauce. Low FODMAP at a small serve. Some brands include garlic; read the label.
• Sriracha and hot sauces. Most sriracha lists garlic. Chili-only hot sauces (Tabasco, Cholula in small serves) are safer defaults.
• Peanut butter (100% peanuts). Low FODMAP at 2 tablespoons. Skip any brand with added inulin or "prebiotic fiber."
• Jam, jelly. Strawberry, raspberry, and blueberry jams are low FODMAP at a small serve. Skip apple, pear, and mango jams, and anything sweetened with HFCS or polyols.

Skip barbecue sauce (onion and garlic), teriyaki sauce, most salad dressings, hoisin, oyster sauce in large serves, most salsas, and any sauce with "natural flavors" as a catch-all.

Stock the pantry once, reuse it forever

The pantry is the one-time investment that makes the rest of the diet run on autopilot. Once the oils, vinegars, single-spice jars, grains, canned goods, baking basics, and condiments are in the cupboard, every meal becomes a produce-plus-protein decision rather than a "do I have anything to cook this with" problem. Pair with the weekly low-FODMAP grocery list, the 7-day meal plan, and the recipes page.

Tracking what you eat and how you feel is the other half of making elimination work. The FODMAP Tracker app handles the serving-size math on every pantry ingredient so you don't have to look it up mid-recipe. The app is in development; join the waitlist below for early access.
