Bone Broth on Stovetop: Easy Recipe & Simmer Times
Quick answer: To make bone broth on a stovetop, put chicken or beef bones into a large pot, cover with water, add optional vegetables and aromatics, bring to a boil, then reduce to a gentle, supervised simmer. Start checking the flavor after about 3 to 6 hours for chicken or 4 to 8 hours for beef, adjusting for the type and size of bones. Strain and refrigerate promptly in shallow containers. These are approximate starting ranges, not required minimums.
Bone broth is one of the few apartment homesteading projects that turns something most people throw away — bones — into a kitchen staple worth several dollars a cup at the grocery store.
It needs no special equipment beyond a sturdy stockpot, but a stovetop simmer should be checked regularly and must not be left unattended overnight. The only real skill involved is understanding temperature and time, since that's what separates a rich, gelatinous broth from a thin, flavorless one — and it's also the part that matters most for food safety.
This guide covers the full stovetop method from start to finish, with practical simmer-time ranges, food-safety guidance, and ways to judge the broth by flavor and aroma rather than a rigid clock.

What Is Bone Broth, Really?
Bone broth is made by simmering animal bones — along with some meat, vegetables, and aromatics — in water for an extended period, far longer than a typical soup stock. That extended time is the entire point.
Collagen in connective tissue gradually softens and yields gelatin during moist cooking; there is no single temperature and duration that guarantees a particular broth texture. This is a slow chemical process, not something that happens just by getting the water hot. Flavor and gelatin are released over time, but the amounts vary with the ingredients and cooking conditions. Simmering longer does not guarantee a specific nutrient content or a firm gel.
This is also why bone broth differs from regular stock. Stocks and bone broths both extract flavor and gelatin from bones and connective tissue. A longer simmer can produce a fuller-bodied broth, but no fixed 12-to-24-hour window is required for a useful result; bone type, size, and water quantity matter.
What You'll Need
- 2 to 3 lbs of bones — chicken carcass and feet, beef marrow and knuckle bones, or fish heads and frames. Mix bone types if you like; the principle is the same
- A large stockpot with a heavy bottom — heavy-bottomed pots distribute heat more evenly and reduce the risk of scorching during a long simmer
- A tight-fitting lid — helps maintain a steady temperature and reduces evaporation over a long cook
- 1 to 2 tablespoons of apple cider vinegar — the acid helps draw minerals out of the bone over the long simmer. If you've made your own from scraps, this is a perfect use for it
- Aromatics — a roughly chopped onion, 2 to 3 carrots, 2 to 3 celery stalks, a couple of bay leaves, and whole peppercorns are the classic base
- A fine mesh skimmer or large spoon — for removing foam during the first hour of cooking
- A fine mesh strainer or cheesecloth — for straining the finished broth
- A food thermometer — the single most useful tool for getting this right consistently, especially for your first few batches
Step-by-Step Instructions
- Optional — roast the bones first. For beef or other red meat bones, roasting at 450°F for 20 to 25 minutes before simmering deepens the flavor and produces a darker, richer broth. This is a flavor preference, not a safety requirement, and chicken bones are usually skipped straight to the pot.
- Add the bones to the pot. Place the bones in your stockpot and add cold or lukewarm water until it covers the bones by about 2 inches.
- Add the vinegar. Stir in the apple cider vinegar and let the pot sit for 20 to 30 minutes before turning on the heat. Vinegar is optional and mainly affects flavor; there is no need to wait for it to soften the bones before heating.
- Bring to a boil. Turn the heat to high and bring the pot to a full boil, uncovered.
- Skim the foam. As the water comes to a boil, grey foam will rise to the surface. Skim foam as it appears during the early cooking stage for a cleaner-looking broth. Skimming can improve clarity, but appearance alone does not determine whether broth is safe to eat.
- Reduce to a gentle simmer. Lower the heat until the broth shows only small, occasional bubbles breaking the surface — not a rolling boil. Add the onion, carrots, celery, bay leaves, and peppercorns at this point. Check your water level periodically and top up with hot water if it drops below the bones.
- Maintain the simmer. Keep the broth at this gentle simmer, partially covered, for the appropriate time for your bone type — see the table below.
- Strain. Once finished, remove the pot from heat and strain the broth through a fine mesh strainer or cheesecloth into a large bowl or pot, discarding the solids.
- Cool quickly. This is the most important food safety step in the entire process — see the safety section below before you do anything else with your finished broth.
Typical Simmer Times by Bone Type
Cooking time varies with the size and type of bones, how much water you use, and the flavor you want. The ranges below are starting points for gently simmered stock, not minimum safety thresholds or guarantees of a firm gel. Taste as you go and stop when the flavor is developed. For context, see The Culinary Pro's stock-making guidance.
| Bone Type | Simmer Time | Notes |
|---|---|---|
| Fish bones / heads | 30–60 minutes | Breaks down fastest; longer cooking can turn it bitter |
| Chicken bones | 3–6 hours | Joints and feet can contribute gelatin; thickness also depends on water quantity |
| Beef / red meat bones | 4–8 hours | Roasting first deepens flavor and color |
| Vegetable stock | 30–60 minutes | Vegetable tissue breaks down much faster than bone |
The Food Safety Rules That Actually Matter
Bone broth's long, low simmer makes it different from most cooking projects, and that raises real food safety questions worth answering directly rather than glossing over.
Keep the temperature in the safe zone throughout the simmer. The broth needs to stay hot enough, consistently, to prevent bacterial growth over such a long cook. Maintain a steady, gentle simmer while cooking. USDA guidance identifies 140°F (60°C) as the minimum hot-holding temperature, not the target temperature for simmering. A food thermometer removes the guesswork here, especially while you're still learning what a "gentle simmer" looks like on your specific stove.
Never leave it unattended on a gas stove overnight, full stop. This is a genuine fire safety issue, not just a food safety one. If you want to run a multi-hour or overnight simmer safely, a slow cooker or programmable multi-cooker set to maintain temperature is the safer choice for unattended cooking — both because it removes the open-flame risk and because the USDA recommends keeping these appliances at or above 140°F throughout the process specifically to prevent bacterial growth. On a stovetop, plan to be home and awake to monitor the pot, or switch it to a slow cooker before you leave or go to bed.
Cool the finished broth quickly — this is the step people skip. Once your broth is done, the single most important food safety step is cooling it fast rather than leaving the hot pot sitting on the counter or stove for hours, which is exactly the temperature range bacteria multiply fastest in. The fastest way to do this at home is to strain the broth into a few smaller, shallower containers rather than one large pot, since smaller volumes lose heat far faster. Placing those containers in an ice bath, or even just spreading the bones and solids out on a tray to cool separately from the liquid, speeds things up considerably. Transfer the broth to shallow containers and refrigerate within two hours of finishing (within one hour if the surrounding temperature is above 90°F/32°C); use an ice bath to speed cooling. See USDA guidance on cooling leftovers.
Once refrigerated, use it within 4 days, or freeze it. Cooked bone broth doesn't last indefinitely in the fridge. If you won't use it within four days, freeze it — broth freezes extremely well and loses very little quality.
How to Judge Broth Flavor and Body
A refrigerated gel can indicate a gelatin-rich broth, but it is not a reliable test of doneness, extraction completeness, or food safety.
Spoon a small amount of the finished broth into a dish and chill it in the fridge for an hour. Broth with enough dissolved gelatin may set into a jelly-like consistency when chilled, but some well-made broths remain liquid. A liquid result may reflect fewer collagen-rich bones, more water, or a less concentrated broth; adding time alone is not always the answer.
A few other cues worth checking alongside the gel test: the broth should coat the back of a spoon with noticeable body, color can vary widely according to the bones, roasting, and other ingredients. Meat and connective tissue should also separate easily from the bones by the time you strain it.
Common Troubleshooting
My broth is cloudy instead of clear. A vigorous boil may suspend particles and make broth cloudy, but cloudiness has several possible causes and is not by itself proof of spoilage. Keep the temperature below a rolling boil throughout the cook, and skim the foam thoroughly during that first hour — both make a noticeable difference in clarity.
My broth didn't gel at all. A broth can taste excellent without setting into a gel. The amount of cartilage and connective tissue, water quantity, and reduction all affect the texture. For more body, use more collagen-rich bones or less water next time; do not treat gel formation as a safety or doneness test.
My broth tastes bitter. Cooking certain ingredients for too long, especially fish bones and some vegetables, may create harsh flavors; overly high heat can also affect the result. This happens most often with fish broth, which cooks faster than people expect.
I'm nervous about leaving it simmering for that long. That instinct is reasonable, especially on a gas stove. Switch to a slow cooker or a programmable multi-cooker for any simmer you can't personally supervise — both hold a safe, steady temperature without the fire risk of an unattended open flame.
Storage and Freezing
Bone broth is one of the most freezer-friendly things you can make at home. Once cooled and refrigerated, portion it into freezer-safe containers, silicone cube trays for small portions, or freezer bags laid flat to save space. Frozen bone broth keeps well for several months and thaws quickly in the fridge or directly in a pot over low heat. Freezing in smaller portions — a cup at a time, or ice cube portions for cooking — means you can pull out exactly what you need without thawing an entire batch.
Frequently Asked Questions
Is it safe to leave bone broth simmering on the stove overnight?
On a gas stove, this isn't recommended — it's a genuine fire safety risk to leave an open flame unattended for hours while you sleep. If you want an overnight or multi-hour simmer you can't personally supervise, a slow cooker or programmable multi-cooker is the safer option, since it holds a steady, safe temperature without an open flame and without needing to be watched.
What temperature should bone broth simmer at?
Use a gentle, steady simmer with small bubbles rather than a rolling boil. USDA's 140°F (60°C) threshold applies to keeping cooked food hot; it is not a target simmer temperature. Avoid letting cooked broth cool into the danger zone during a long cooking session.
How do I know when my bone broth is actually done?
Taste the broth for a developed flavor and check its body. A spoonful chilled in the fridge may set if the broth contains enough gelatin, but remaining liquid does not mean it is undercooked or unsafe.
Can I reuse the same bones for a second batch of broth?
Yes, this is sometimes called a "second broth." The bones will have given up most of their collagen and minerals by the end of a full simmer, so a second batch will be noticeably lighter and less gelatinous than the first, but it's still a useful, flavorful base for soups and is a good way to extract every bit of value from the bones before discarding them.
How long does bone broth last in the fridge or freezer?
Once properly cooled and refrigerated, use bone broth within about 4 days. For longer storage, freeze it — properly frozen bone broth keeps well for several months with very little loss in quality, and portioning it into smaller containers or ice cube trays makes it easy to use exactly what you need.
Why does my broth need to be cooled quickly after cooking?
A pot of hot broth left sitting out for hours sits directly in the temperature range where bacteria multiply fastest. Straining the broth into smaller, shallower containers rather than one large pot, and using an ice bath if possible, cools it much faster and gets it safely into the fridge within a couple of hours rather than leaving it out on the counter or stove.
Final Thoughts
Bone broth is the kind of project that feels intimidating before you start and almost completely hands-off once it's actually going. The bones do most of the work — your job is mostly just keeping the temperature steady and being patient.
It's also one of the more natural extensions of a zero-waste kitchen. The carcass from a roast chicken, the bones leftover from a cut of beef, even the trimmings from vegetables you'd otherwise toss — all of it has a second life here instead of going straight in the bin.
