Pro Tips

Roast First: Roast bones at 400°F for 30–45 minutes before simmering. This develops deeper, more complex flavor and richer color.
Skim Foam: Skim the gray foam that rises in the first 30–60 minutes. This removes impurities and keeps the broth clear.
Strain Well: Strain through a fine-mesh sieve lined with cheesecloth for crystal-clear broth. Discard solids after straining.
Cool Quickly: Use an ice bath to cool broth below 40°F within 2 hours. A gel-like consistency when cold means high collagen—that is ideal.

Example Calculations

14 Quarts Beef Broth (Stovetop)

IntensityMedium (Everyday Broth)

Cost per Quart$3.50–$5.50

Bones: 4 qt × 1.0 lb/qt = 4.0 lb. Water: 4 / (1 − 0.25) = 5.33 qt to account for 25% stovetop evaporation. Cost: 4 lb × $3–$5 + $2 vegetables = $14–$22 total, or $3.50–$5.50/qt.

Simmer Time8–12 hours
Cost per Quart$1.25–$2.00

Bones: 8 qt × 0.75 lb/qt = 6.0 lb. Water: 8 / (1 − 0.125) = 9.14 qt for 12.5% slow cooker evaporation. Cost: 6 lb × $1–$2 + $4 vegetables = $10–$16 total, or $1.25–$2.00/qt.

34 Quarts Rich Beef Broth (Pressure Cooker)

Cost per Quart$5.00–$8.00

Bones: 4 qt × 1.5 lb/qt = 6.0 lb. Water: 4 / (1 − 0.05) = 4.21 qt for 5% pressure cooker evaporation. Simmer: 24–48h ÷ 3 = 8–16h. Cost: 6 lb × $3–$5 + $2 vegetables = $20–$32 total, or $5.00–$8.00/qt.

Frequently Asked Questions

Q

How many pounds of bones do I need per quart of bone broth?

For a medium-bodied everyday broth, use 1 lb of beef bones or 0.75 lb of chicken bones per quart of finished broth. For a richer, gelatinous broth, increase to 1.5 lb beef or 1 lb chicken per quart. Light stock uses less: 0.75 lb beef or 0.5 lb chicken per quart.

  • Light stock: 0.75 lb beef, 0.5 lb chicken, 0.6 lb pork per quart
  • Medium broth: 1.0 lb beef, 0.75 lb chicken, 0.8 lb pork per quart
  • Rich concentrated: 1.5 lb beef, 1.0 lb chicken, 1.2 lb pork per quart
  • Knuckle and joint bones yield the most collagen and gelatin
  • Mix marrow bones with knuckle bones for both flavor and body

Q

How long should I simmer bone broth?

Chicken bone broth needs 4–24 hours depending on intensity. Beef bones need 8–48 hours. A pressure cooker cuts these times by roughly two-thirds. Medium-bodied chicken broth takes 8–12 hours on the stovetop, while a rich beef broth needs 24–48 hours for maximum collagen extraction.

  • Chicken light stock: 4 hours stovetop, about 1.5 hours in a pressure cooker
  • Chicken medium broth: 8–12 hours stovetop, 3–4 hours pressure cooker
  • Beef medium broth: 18 hours stovetop, 6 hours pressure cooker
  • Beef rich broth: 24–48 hours stovetop, 8–16 hours pressure cooker
  • Slow cooker times match stovetop; set to low and leave overnight
Q

Does apple cider vinegar really help in bone broth?

Yes. Adding 1 tablespoon of apple cider vinegar per quart of water helps draw minerals like calcium, magnesium, and phosphorus out of the bones. The acidity breaks down the bone matrix more efficiently. Let bones soak in cold water with vinegar for 30 minutes before heating for best results.

  • Use 1 tbsp ACV per quart of starting water
  • Soak bones in cold water with ACV for 20–30 minutes before heating
  • White vinegar or lemon juice work as substitutes if you lack ACV
  • The vinegar taste cooks off completely during the long simmer
  • ACV helps extract up to 20% more calcium compared to water alone
Q

How much water evaporates during bone broth simmering?

Stovetop simmering loses 20–30% of the water to evaporation over long cooks. A slow cooker with a lid loses only 10–15%. A pressure cooker loses about 5% since the lid seals. Always start with more water than your desired yield to account for evaporation.

  • Stovetop: expect 25% average evaporation over a 12–24 hour simmer
  • Slow cooker: 10–15% loss with the lid on; keep the lid sealed
  • Pressure cooker: only 5% loss due to the sealed environment
  • For 4 quarts finished broth on stovetop, start with about 5.3 quarts of water
  • Check water level every 4–6 hours on stovetop; add hot water if bones become exposed

Q

Is homemade bone broth cheaper than store-bought?

Homemade bone broth typically costs $1–$4 per quart depending on bone type, while store-bought runs $5–$8 per quart. Chicken broth is the cheapest to make at $1–$2 per quart, especially if you save carcasses from roast chickens. Beef bone broth costs $3–$5 per quart for bones alone.

  • Chicken bone broth: $1–$2/qt homemade vs $5–$8/qt store-bought
  • Beef bone broth: $3–$5/qt homemade vs $6–$10/qt premium brands
  • Save roasted chicken carcasses to make broth essentially free
  • A 16-quart batch of chicken broth costs roughly $8–16 to make at home
  • Vegetables add about $0.50 per quart to the total cost
