This hot sauce is vibrant, zesty, and simple. It brings a smooth heat that enhances dishes without causing FODMAP triggers. With no onion or garlic, it’s low FODMAP, gentle on your gut, and full of personality. It’s easy to prep and keeps well—ideal for busy cooks seeking a delicious, gut‑safe kick.

Ingredients Needed

1 lb fresh chilies (jalapeño, serrano, Fresno, poblano, habanero, or a mix): choose your favorite heat level.
⅛–¼ tsp garlic-infused oil (just the oil, not garlic pieces, to add savory flavor without FODMAPs).
2 Tbsp minced green onion tops (green parts only): use only the green parts—they’re low FODMAP and add freshness.
2 Tbsp kosher salt: enhances flavor without FODMAP issues.
1 ½ cups distilled white vinegar: delivers tang and helps preserve the sauce.
Optional: pinch of asafoetida powder (hing)—just a tiny amount adds depth if desired and is low FODMAP in very small quantities.

How To Make Low FODMAP Hot Sauce

Pulse & Ferment:
Pulse the chilies, green onion tops, garlic‑infused oil, and kosher salt in a food processor until coarsely pureed. Transfer to a 1-quart glass jar. Loosely cover (e.g., with a lid set on top, not sealed) and let sit at room temperature overnight to develop flavor gently.

Add Vinegar & Rest:
Stir in the vinegar, cover loosely again, and let it rest at room temperature for 1–7 days. The longer it sits, the deeper the flavor—taste daily until you reach preferred brightness and heat.

Blend Smooth:
Once fermented to your liking, blend the mixture until smooth. Transfer to bottles or jars, then refrigerate.

Recipe Tips

Use green onion tops, not bulbs—they’re low FODMAP and add a mild fresh note.
Don’t use garlic or onion, they’re high FODMAP and can trigger symptoms—use garlic‑infused oil instead.
Check vinegar—most distilled vinegars are low FODMAP, but avoid cider or balsamic that may contain high FODMAP sweeteners.
Label your ferment with the date—best flavor usually between days 3–5.
Taste carefully—start with mild chilies if you prefer less heat, or mix peppers for nuanced spice.

How to Store & Reheat

Room Temperature: Not recommended—keep it chilled to preserve freshness.
Fridge: Store up to 4 months. Shake before using—separation is natural.
Freezer: Freeze in ice cube trays for single‑serve portions; thaw as needed—great for long-term storage.

FAQs

Q: Is garlic‑infused oil safe on a low FODMAP diet?
Yes, the fructans in garlic are not soluble in oil. If only the oil is used (no garlic pieces), it’s low FODMAP.

Q: Can I use onion powder or onion salt?
No—both are high in FODMAPs and can cause issues. Use green onion tops instead for flavor.

Q: How do I adjust the heat level?
Choose milder chilies like jalapeño or poblano, or remove seeds and membranes to reduce heat. For more heat, add habanero or keep seeds in.

Q: Can I skip fermentation?
You can, but resting the sauce overnight enhances flavor depth. Even 1 day of rest improves taste without needing a full 7-day ferment.
