Stocks & broths

chicken stock

fond de volaille · A clear, deeply flavored liquid made by gently simmering chicken bones, connective tissue, and aromatics in water. The collagen in bones hydrolyzes into gelatin, extracting body and mouthfeel. The defining stock of classical cuisine: neutral enough to be the foundation of countless preparations, yet rich enough to carry them. This is the white stock variant — simmered from raw bones rather than roasted, yielding a pale, delicate, purely savory profile.

Family · Stocks & brothsDifficulty · ModerateMake-ahead · YesYield · 1 kg raw chicken bones + 1.5 L water + 100 g mirepoix + 2 g thyme + 1 bay leaf + parsley stems → ~1.2 L finished stock (approximately 8 cups).

The formula

1 kg raw bones : 1.5 L cold water : 10% mirepoix by bone weight

Scale proportionally: 1 kg raw bones (wings, backs, carcasses, feet) + 1.5 L cold water + 100 g mirepoix (50/25/25 onion/carrot/celery) + 2–3 g thyme + 1 bay leaf + parsley stems → ~1.2 L finished stock. Use just enough water to submerge bones; excess dilutes flavor. Never salt during cooking — stock concentrates unpredictably during reduction.

Identity

  • Made from raw bones, not roasted — pale color, delicate flavor
  • Simmered, never boiled — a gentle bubble preserves clarity and body
  • Mirepoix (onion, carrot, celery) at ~10% of bone weight, classically 2:1:1 by weight
  • Collagen fully converted to gelatin — stock sets when chilled
  • Seasoned only at final use, never during cooking

Ingredients

Baseraw chicken bones (wing tips, backs, carcasses, feet)Feet are the single best source of collagen; carcasses provide body and yield. Dark vs. light meat bones: neither is superior — both yield gelatin. Use raw; roasted bones make a brown stock (fond brun de volaille), a distinct preparation.
Liquidcold waterStart cold to extract proteins and impurities into the foam that rises. Starting with hot water seals the surface and produces a cloudy stock.
Aromaticsmirepoix (onion, carrot, celery)Classical ratio: 50% onion, 25% carrot, 25% celery by weight. Rough chop; do not peel the onion (skin adds amber color). The carrot and celery balance and add backbone — do not omit or replace with alliums alone.
Aromaticsaromatic bouquet (bay leaf, thyme, parsley stems)2–3 g thyme + 1 bay leaf + 3–4 parsley stems per liter. Add in the last 30–45 minutes of cooking to preserve volatile aromatics. Do not over-steep — the herbs become bitter and mask the chicken.
Acidwhite wine (optional)A small amount (50–100 mL for 1.5 L) sharpens flavor and brightens the overall profile. Acid is optional but historically correct.
Seasoningsalt (not added during cooking)Stock is NEVER salted during preparation. Salt is added at the point of final use because the stock will be reduced, incorporated into another preparation, or used as a seasoning component itself.

Method

  1. 1Blanch the bones: cover with cold water, bring to a boil, drain, and rinse the bones and pot thoroughly.Raw bones carry blood, proteins, and impurities that produce a cloudy, bitter stock. Blanching coagulates these proteins into a firm white foam (scum) that is discarded, yielding a clean base.
  2. 2Return blanched bones to the clean pot. Add cold water to just cover. Bring to a gentle simmer over medium heat.Cold starting water combined with a slow bring-up prevents the surface proteins from seizing and trapping impurities. A gentle simmer (85–90°C / 185–194°F) extracts gelatin without agitation, keeping the stock clear.
  3. 3Skim the foam thoroughly during the first 15–20 minutes of simmering. Add the mirepoix and aromatic bouquet.Continuous skimming removes residual protein and fat. Adding aromatics at this stage (after the major impurities have been addressed) prevents over-extraction of the alliums and ensures the bouquet's volatiles survive to the finished product.
  4. 4Maintain a bare simmer (a few lazy bubbles breaking the surface) for 3–4 hours. Do not stir. Add water only if necessary to keep bones submerged.Extended gentle heat is required for complete collagen hydrolysis. Stirring or boiling churns the liquid, oxidizes lipids, and clouds the stock. The goal is equilibrium: maximum extraction with minimum turbulence.
  5. 5Strain through a fine-mesh sieve lined with damp cheesecloth (or a dedicated stock strainer) without pressing the solids.Pressing extracts bitter, astringent compounds from the cooked vegetables and bone fragments. Cheesecloth catches fine particulate matter for a crystal-clear result.
  6. 6Cool rapidly in an ice bath to below 10°C within 30 minutes. Refrigerate at 4°C or below.Bacteria multiply rapidly between 10–60°C. Rapid cooling passes through the danger zone quickly. Properly cooled, stock keeps 3–4 days refrigerated.

Techniques that matter

Blanching and draining

Removes blood, proteins, and cellular debris that cause cloudiness, bitterness, and off-odor. Non-negotiable for clear stocks.

Bain-marie or gentle simmer

Maintains precise temperature control. Boiling turbulence shatters fat globules into the liquid, creating an opaque emulsion rather than a clear broth.

Strain without pressing

Preserves clarity and prevents bitter, tannic extraction from overcooked vegetables and bone fragments.

Variations & derivatives

brown chicken stock (fond brun de volaille)classical French

Bones are roasted at 200°C until deeply caramelized before simmering. The Maillard reaction creates hundreds of new flavor compounds, yielding a darker, more robust, slightly sweet stock used for brown sauces (demi-glace, gravy bases). A distinct preparation, not a variation of white stock.

remouillageclassical French

A second stock made by re-covering already-used bones with fresh cold water and simmering 1–2 hours. Lower in gelatin and flavor than the first pull, but serviceable for glazes or risotto.

consommé baseclassical French

A fortified chicken stock deliberately concentrated 2–3× by reduction. Used as the liquid base for clear soup, where egg-white raft clarification creates a perfectly transparent, flavored consommé.

pho broth (nước dùng gà)Vietnamese

Chicken bones toasted until golden, simmered with charred onion, ginger, fish sauce, and spices (star anise, cinnamon, clove). The Vietnamese-American variant of chicken stock is intensely aromatic and spiced, fundamentally different in character from the classical French approach.

Substitutions

  • chicken feetadd more wing tips and backsFeet are richer in gelatin because of the high connective tissue in the skin and tendons. If unavailable, increase the ratio of high-collagen bones. Carcasses alone yield a thin stock.changes result
  • mirepoixleek + parsnip + celeryFor a FODMAP-sensitive kitchen, use the white part of leek (low-FODMAP) and parsnip (provides the sweetness carrot would). Celery leaves add aromatic depth. This is a functional substitution, not equivalent.changes result
  • white winesherry vinegar (1 tsp/L)Vinegar mimics wine's acidity without the alcohol or the step of deglazing. Add with the aromatics. The stock will taste subtly different — sharper and less complex.

Troubleshooting

Stock is cloudy or murky

Boiling during cooking (agitation shatters fat and protein into the liquid) OR insufficient skimming OR bones not blanched firstRestart with blanched bones. Simmer gently — a single bubble breaking the surface is sufficient. Do not stir. Strain through cheesecloth.

Stock tastes flat or watery

Insufficient simmer time (collagen not fully hydrolyzed) OR too much water relative to bones (diluted extraction) OR under-reduction at the endExtend the simmer to 4 hours. Reduce the finished stock by one-quarter over medium heat to concentrate flavor. Add a splash of wine vinegar during cooking for acidity.

Stock congeals when refrigerated but has no body

Not enough collagen-containing bones — too many carcasses, too few feet, necks, or wing tipsAdd chicken feet (200–300 g per liter) for superior gelatin extraction. Feet are the single most efficient source of natural gelatin in the chicken.

Stock has an unpleasant, gamey, or iron-like off-flavor

Blood not fully purged during blanching OR decomposed proteins from over-cooking OR old or improperly stored bonesEnsure the blanching water reaches a full boil and the foam is completely discarded. Use very fresh bones (within 24 hours of butchery if possible). Reduce the simmer time to 3 hours maximum.

Storage

Keeps 3–4 days refrigerated; 4–6 months frozenRefrigerate in airtight containers once cooled below 10°C. For longer storage, freeze in portions (ice cube trays for small amounts, zip-lock bags laid flat for 1–2 cup portions). Label with date. Reheat: Thaw overnight in refrigerator. Reheat gently in a saucepan to a full boil (100°C) for 1 minute to ensure food safety, then use at the temperature required by the recipe.
