Low FODMAP Sauces and Condiments You Can Actually Eat

Quick answer: Monash-tested low FODMAP servings include regular or Dijon mustard at 1 tablespoon, regular or low-fat mayonnaise at 1 tablespoon, soy sauce at 2 tablespoons, and tamari at 1 tablespoon. For sriracha, the sauce matters: regular sriracha is 1½ teaspoons, while our Monash Certified Low FODMAP Sensitive Sriracha is about 5 teaspoons. Serving sizes vary by sauce, so check the table below before you pour.

Garlic and onion show up in an impressive number of bottles. Ketchup, salad dressing, pasta sauce, barbecue sauce, and chili sauce can all look straightforward until you turn the label around.

The good news is that low FODMAP food does not have to mean eating everything plain. This guide gives you a practical way to compare sauces, read condiment labels, and build a pantry that makes weeknight food taste like food again.

Low FODMAP Sauces and Condiments at a Glance

Use this table as a shopping shortcut. The portions below are based on Monash-tested servings for the specified condiment types. Match the exact product and serving size, because recipes vary. The high-fructose corn syrup ketchup amount is rounded down to about 3 teaspoons for a simple kitchen measure.

Why Labels and Serving Sizes Both Matter

Low FODMAP is not always a simple yes-or-no label. The amount you eat can change whether a food fits the diet. A sauce may also combine several ingredients that need to be considered together.

Start with the ingredient list. Look closely for garlic, garlic powder, onion, onion powder, honey, high-fructose corn syrup, chicory root, inulin, and concentrated fruit ingredients. Terms such as “spices,” “natural flavors,” broth, or seasoning blends may also deserve a closer look when the label does not give you enough detail.

Then check the serving size using the Monash University FODMAP Diet app. Monash notes that serving size can significantly change a food's FODMAP rating.

What Condiments Are Low FODMAP?

Is Ketchup Low FODMAP?

For the Monash-tested ketchup types in the table, the low FODMAP serving is 3 teaspoons for ketchup with sucrose. For ketchup with high-fructose corn syrup, use about 3 teaspoons, rounded down from the tested amount for an easy kitchen measure.

Three teaspoons equals 1 tablespoon, enough for a measured dip alongside fries or a spread on a burger. Match the ketchup type and check the exact bottle: these portions do not establish the FODMAP content of every brand or flavored version.

Is Mustard Low FODMAP?

Monash-tested servings for regular mustard and Dijon mustard are 1 tablespoon each. Use regular mustard on a sandwich or burger, or stir Dijon into an oil-and-vinegar dressing for a tangy finish.

Honey mustard and other flavored varieties need a separate check. Added honey, garlic, onion, or seasoning blends can make them different from the mustard types listed here.

Is Mayonnaise Low FODMAP?

Regular and low-fat mayonnaise have Monash-tested low FODMAP servings of 1 tablespoon each. Spread it on a sandwich or use it as the creamy base for a dip. For a quick chili mayo, stir a little Sensitive Sriracha into your measured mayonnaise portion, keeping both condiments within their listed servings.

Garlic aioli and flavored mayonnaise need their own ingredient and serving check. The portions for regular and low-fat mayo do not automatically apply to them.

Are Soy Sauce and Tamari Low FODMAP?

Use the serving for the sauce you have: plain soy sauce has a Monash-tested low FODMAP serving of 2 tablespoons; plain tamari has a serving of 1 tablespoon. They can play a similar role in cooking, but their listed portions are different.

Try either with rice vinegar and a little maple syrup for a rice-bowl dressing or noodle sauce. Measure the amount per person, especially when making a batch for several meals. Check seasoned sauces and marinades separately for added garlic, onion, or sweeteners. If you also need to avoid wheat, check that claim on the bottle; wheat-free and low FODMAP are separate checks.

Is Hot Sauce Low FODMAP?

The exact sauce and portion matter. The Monash-tested low FODMAP serving for regular sriracha is 1½ teaspoons (½ tablespoon). Sensitive Sriracha is Monash Certified Low FODMAP at about 5 teaspoons. Use the portion for the specific sauce, rather than applying either amount to every hot sauce.

A measured drizzle works well on eggs, tacos, or a rice bowl. For a closer look at the difference, read Is Sriracha Low FODMAP? or our guide to hot sauce without garlic bulb or onion. If you are comparing chili sauces, this chili sauce label-reading guide explains what to check on the bottle.

Garlic-Infused Oil: A Useful Flavor Shortcut

Garlic contains fructans, which are water-soluble rather than oil-soluble. When whole pieces of garlic are infused into oil and completely removed, the flavor can remain in the oil without the fructans transferring in the same way. Monash recommends garlic-infused oil as one way to bring garlic flavor back into low FODMAP cooking.

Use a commercially prepared product or follow reliable food-safety guidance if you make infused oil at home. You can read Monash's explanation in its low FODMAP FAQ.

How Monash Certification Changes the Label Check

An ingredient list is useful, but it cannot show the finished product's measured FODMAP content. Monash certification means the product has been independently tested against Monash's low FODMAP criteria at the recommended serving size.

Certification does not mean a product treats symptoms or that serving size no longer matters. It gives you tested information about the food itself. Our guide to what Monash Certified Low FODMAP means explains the testing and serving-size piece in more detail.

Easy Low FODMAP Sauce Combinations

Once you have a few checked ingredients, dinner gets much easier. Try:

• Tamari, rice vinegar, and maple syrup: Whisk into a quick glaze for rice bowls, noodles, or roasted vegetables.
• Garlic-infused oil, lemon juice, and herbs: Spoon over potatoes, chicken, fish, or salad.
• Mayonnaise, Dijon, and vinegar: Stir together for a creamy dip or sandwich sauce.
• Sensitive Sriracha and mayonnaise: Mix into a creamy chili sauce for fries, sushi bowls, sandwiches, or roasted potatoes.
• Sensitive Sriracha and maple syrup: Brush onto roasted carrots, salmon, or crispy tofu.

Check each ingredient and portion for your own low FODMAP plan. The goal is not to memorize every bottle in the aisle. It is to know what to look for and keep a few dependable options within reach.

The Bottom Line
