Chicken Broth
Homemade chicken broth without onion or garlic.
Ingredients
- 3 to 4 lb (1.4 to 1.8 kg) chicken — a whole chicken, a carcass plus wings, or bone-in thighs and drumsticks
- 12 cups (2.8 L) cold filtered water
- 2 medium carrots, roughly chopped
- 1 to 2 stalks celery, roughly chopped
- Green tops of 1 large leek, rinsed and roughly chopped (about 1 cup)
- Green tops of 4 to 5 scallions, roughly chopped
- 6 sprigs fresh parsley
- 4 sprigs fresh thyme
- 1 bay leaf
- 1 tsp whole black peppercorns
- Salt, to taste (added after straining)
Instructions
Build the Pot
- Place the chicken in a large stockpot or slow cooker. Don't rinse raw chicken — it splashes bacteria around the sink.
- Add the carrots, celery, leek greens, scallion greens, parsley, thyme, bay leaf, and peppercorns.
- Pour in the cold water. It should cover everything by an inch or two. Do not add salt yet.
Simmer
- Bring to a gentle boil over medium-high heat, then drop to low. Foam will rise; skim it off with a spoon for the first few minutes.
- Hold at a bare simmer (small occasional bubbles, not a rolling boil) for 3 to 4 hours on the stovetop, or 8 to 10 hours on low in a slow cooker.
- If the water drops below the solids during a long simmer, top it off with hot water.
Strain and Cool
- Turn off the heat and let the pot sit for 10 minutes so the solids settle.
- Pour through a fine-mesh sieve into a clean pot or large bowl. Discard the vegetables and aromatics. Pull any usable meat off the bones for another use.
- For a clearer broth, strain a second time through cheesecloth.
- Salt to taste now that the volume is set.
- Cool quickly by setting the container in an ice bath or dividing into shallow containers. Refrigerate within 2 hours of cooking.
- Skim the solid fat layer off the top the next day if you want a leaner broth, or leave it for richness.
Tips & Substitutions
- Use whatever chicken you have. A whole bird gives the best balance of flavor and body. A leftover roast carcass plus 1 to 2 pounds of wings works almost as well, and wings alone make a rich gelatinous broth.
- Leek greens and scallion tops are the onion swap. Fructans are concentrated in the white bulb of both plants; the dark green tops are low-FODMAP and carry the onion flavor you want in a broth. Leek green tops are low-FODMAP up to 54g per serve, scallion greens up to 75g per serve.
- Add garlic-infused olive oil at the end if you want a garlic note. Stir 1 to 2 teaspoons into the finished broth. Adding it to the simmering pot wastes the flavor.
- Skip pre-seasoned rotisserie chicken. Grocery-store rotisserie birds are usually rubbed with onion and garlic powder, which will leach into the broth.
- If you don't want to make it, Fody Low-FODMAP Chicken Soup Base and Gourmend Organic Chicken Broth are Monash-certified and onion/garlic-free. Most other supermarket broths (Swanson, Pacific, Kitchen Basics, Better Than Bouillon) contain onion or garlic.
- Celery is dose-dependent for mannitol. 1 to 2 stalks spread across a 10-cup batch keeps the per-bowl amount small. If you're sensitive to polyols, use one stalk or skip it.
Why This Works
The store-bought broth trap. Swanson, Pacific, Kitchen Basics, and Better Than Bouillon almost all list onion powder, garlic powder, or both in their ingredient decks. A single cup can put a sensitive reader over the fructan threshold before the soup even starts.
Leek greens and scallion tops do the work. Fructans sit in the white bulb of alliums, not the green tops. The greens carry the aromatic volatile compounds that make broth taste like broth, without the FODMAP load.
Celery is fine in a broth context. Celery's FODMAP load is mannitol, and it climbs with serve size. One to two stalks spread across 10 or so cups of broth keeps the per-bowl amount well under the Monash low-FODMAP threshold.
Homemade is the baseline. Because onion and garlic powder are in almost every commercial stock, a clean homemade pot is the only way to know exactly what's in the broth you're cooking with.
Storage
Refrigerate in sealed containers at 40°F (4°C) or below for 3 to 4 days. For longer storage, freeze in 2-cup portions for soups and stews, and in a silicone ice-cube tray (about 2 tablespoons per cube) for deglazing pans or finishing sauces. Frozen broth keeps for up to 3 months. Thaw overnight in the fridge, or add cubes straight to a hot pan.
