    A garlic-and-onion-free stir fry sauce that's savory, sweet, and gut-friendly. Ready in 5 minutes with pantry staples.

    Ingredients

    • 1/4 cup gluten-free tamari (or 2 tbsp regular soy sauce max)
    • 2 tbsp maple syrup
    • 1 tbsp rice vinegar
    • 1 tbsp garlic-infused olive oil
    • 1 tsp freshly grated ginger
    • 1 tsp sesame oil
    • 1 tbsp cornstarch
    • 1/4 cup water

    Instructions

    1. Whisk cornstarch into the water until fully dissolved. This prevents lumps.
    2. In a small bowl, combine tamari, maple syrup, rice vinegar, garlic-infused oil, ginger, and sesame oil.
    3. Stir in the cornstarch slurry.
    4. Pour into your hot pan during the last 2 minutes of stir-frying — it thickens instantly.
    5. Toss with cooked protein and vegetables until glossy.

    Why This Sauce Works

    Traditional stir-fry sauces rely on garlic, onion, and honey — all high FODMAP. This version uses garlic-infused oil (FODMAPs aren't oil-soluble) and maple syrup in place of honey.

    Serving & Portion Notes

    Storage

    Refrigerate in a sealed jar up to 5 days. Shake before using.

    FODMAP Notes and Serving Tips

    A stir-fry sauce is where hidden FODMAPs often appear. Many bottled sauces contain garlic, onion, wheat, honey, apple juice concentrate, or high-fructose syrup. This homemade version keeps the ingredient list short and lets you control the serving size.

    Use gluten-free tamari, ginger, maple syrup, rice vinegar, sesame oil, and garlic-infused oil. Toss with rice noodles, rice, chicken, shrimp, firm tofu, carrots, bell pepper, zucchini, or spinach. Add sauce gradually; you can always add more at the table.

    Store extra sauce in the refrigerator for up to five days and shake before using. This recipe is informational only and not medical advice.

    Troubleshooting and Variations

    If the sauce is too salty, add lime juice, water, or a little maple syrup. If it needs more depth, add ginger, sesame oil, chili flakes, or the green tops of scallions. Use it with rice, rice noodles, chicken, shrimp, firm tofu, carrots, spinach, zucchini, or bell pepper. Do not add garlic powder or onion powder, even in small amounts, during elimination. For full meals, pair this sauce with Dinner Recipes and check new vegetables in the Food Checker.

    FODMAP Notes

    Uses tamari and garlic-infused oil to keep FODMAPs low. Maple syrup replaces honey. Limit to 2 tbsp per serving.

    Practical Low FODMAP Notes for Low FODMAP Stir Fry Sauce

    Low FODMAP Stir Fry Sauce is most useful when the serving size stays consistent, because FODMAP tolerance often changes when portions creep upward. Use the listed servings as the starting point, then portion leftovers before storing so the meal stays predictable on busier days. If you are cooking for family members who do not follow a low FODMAP plan, keep onion, garlic, wheat-heavy sides, and high-FODMAP sauces separate at the table instead of mixing them into the main recipe.

    Ingredient notes: this recipe uses 1/4 cup gluten-free tamari (or 2 tbsp regular soy sauce max), 2 tbsp maple syrup, 1 tbsp rice vinegar, 1 tbsp garlic-infused olive oil, 1 tsp freshly grated ginger, 1 tsp sesame oil, 1 tbsp cornstarch, 1/4 cup water, Pinch of chili flakes (optional). Check packaged ingredients carefully, especially broths, spice blends, gluten-free mixes, condiments, and dairy substitutes, because garlic powder, onion powder, inulin, chicory root fiber, high-fructose sweeteners, and wheat-based thickeners can appear in small print. When unsure, choose plain versions and add flavor with garlic-infused oil, fresh herbs, citrus, ginger, chives, scallion greens, or low FODMAP spice blends.

    For IBS-friendly meal prep, cool leftovers quickly and refrigerate in shallow containers. Reheat only the portion you plan to eat, and add fresh herbs, lemon juice, or a small drizzle of garlic-infused oil after reheating to bring the flavor back without relying on high-FODMAP aromatics. If a recipe feels too rich during a flare, pair it with a simple low FODMAP side such as rice, potatoes, quinoa, lettuce, cucumber, carrots, or another tolerated vegetable.

    This recipe is intended for general low FODMAP education, not medical advice. Individual tolerance varies, so use your dietitian’s guidance and your own symptom history when deciding whether to repeat, increase, or modify a serving. During the elimination phase, keep portions conservative; during reintroduction, test one FODMAP group at a time so you can clearly identify personal triggers.

    Helpful next steps: use the FODMAP Food Checker before adding new ingredients, try the Ingredient Swap Tool when a sauce or seasoning is questionable, and save recipes that worked well so you can build a reliable rotation of breakfasts, lunches, dinners, and snacks.

    Storage Tips
