What Makes Traditional Marinara Sauce High in FODMAPs?
At its core, a traditional marinara sauce is made with simple ingredients: tomatoes, aromatics, and herbs. However, it's the specific aromatics and how the tomatoes are processed that create a high-FODMAP load. The primary culprits are garlic and onion, which are rich in fructans, a type of oligosaccharide. For individuals with a sensitive digestive system, these ingredients can trigger symptoms like bloating, gas, and abdominal pain. Concentrated tomato products, such as tomato paste or certain purées, can also be high in the FODMAP fructose when consumed in larger portions. Many manufacturers also add high-fructose corn syrup or use broad, non-specific terms like 'natural flavors' or 'herbs and spices' that can hide high-FODMAP ingredients.
How to Enjoy Low FODMAP Marinara Sauce
Successfully integrating marinara sauce into a low FODMAP diet is achievable by either choosing specially formulated products or preparing a homemade version with a few key modifications. You can still enjoy the rich, savory taste you love while keeping digestive discomfort at bay.
The Store-Bought Route
Several brands now produce certified low FODMAP marinara sauces. These products have been tested to ensure they fall within safe FODMAP thresholds and are explicitly free of ingredients like garlic and onion. Popular brands include:
- FODY Foods: A well-known brand dedicated to low FODMAP products, offering a tasty marinara option.
- Prego Sensitive Recipe: A readily available choice in many supermarkets, specifically formulated without garlic and onion.
- Rao's Sensitive Formula: Another popular brand that offers a sensitive version of its classic marinara.
- Carbone Marinara Delicato: A newer addition that explicitly markets its onion-free and garlic-free formula. When shopping, always check the label for certification logos or specific callouts like 'sensitive recipe' or 'no onion, no garlic'.
The Homemade Route
Making your own marinara gives you complete control over the ingredients, ensuring a safe and delicious result. The secret lies in strategic ingredient swaps:
- Garlic-Infused Oil: To get the robust flavor of garlic without the fructans, use garlic-infused olive oil. FODMAPs are water-soluble, not oil-soluble, so the flavor transfers to the oil while the fructans are strained out.
- Leek Greens: Replace onion by using the dark green parts of leeks. The white bulb contains fructans, but the green tips are low in FODMAPs.
- Plain Canned Tomatoes: Start with plain, whole peeled or diced tomatoes with no added herbs or spices. Be mindful of portion size, as tomatoes still contain fructose. Half a cup (100g) is typically a safe serving.
- Dried Herbs: Use dried oregano, basil, thyme, and rosemary, which are all low FODMAP and add classic Italian flavor.
- Tomato Paste (Portion Controlled): A small amount of tomato paste (about 2 tablespoons or 28g) is considered low FODMAP and can add depth of flavor.

Low FODMAP vs. Standard Marinara Sauce: A Comparison
| Feature | Standard Marinara Sauce | Low FODMAP Marinara Sauce |
|---|---|---|
| Primary Aromatics | Onion and Garlic Bulbs | Garlic-Infused Oil & Leek Greens |
| FODMAP Content | High in fructans and potentially high in fructose | Low in all FODMAPs, when ingredients and serving sizes are managed |
| Flavor Source | Water-soluble fructans and oil-soluble flavors from onion and garlic | Oil-soluble flavors from infused oil, plus herbs |
| Tomato Concentration | Often high in tomato paste or purée, increasing fructose | Uses plain canned tomatoes, with measured use of tomato paste |
| Store-Bought Options | Wide variety, but most are unsuitable due to high FODMAP ingredients | Specific, clearly labeled brands such as Fody and Prego Sensitive |
| Digestive Impact | Can trigger IBS symptoms in sensitive individuals | Designed to be well-tolerated by those on a low FODMAP diet |
Other Considerations for Your Low FODMAP Meal
Beyond the sauce itself, consider other components of your meal to ensure it remains low FODMAP. This includes choosing suitable pasta alternatives like gluten-free pasta (portion-controlled) or brown rice pasta, as conventional wheat pasta is high in fructans. To add more flavor, use a generous amount of low FODMAP herbs like basil or oregano, or add a sprinkle of low-lactose or hard cheese like Parmesan. For more comprehensive information on the low FODMAP diet, consult resources like Monash University.
Conclusion
While a traditional marinara sauce is off-limits during the elimination phase of a low FODMAP diet, your meal plan doesn't have to miss out on this classic favorite. With a little label-reading for store-bought options or some simple modifications for homemade versions, you can still enjoy a rich and flavorful marinara sauce. Focusing on low FODMAP ingredients and mindful portion sizes is key to managing your digestive health without sacrificing delicious food.
