You're probably throwing away the best part of your Sunday roast. Honestly, it’s a tragedy. Most people see a picked-over chicken carcass and see trash, but that skeleton is basically liquid gold waiting to happen. If you've been buying those shelf-stable cartons from the grocery store, I'm sorry to tell you that you’ve been eating flavored salt water. Real, homemade stock is different. It’s viscous. It wobbles when it’s cold. It has a depth that makes a simple chicken noodle soup feel like a warm hug from someone who actually loves you.
Making stock isn't about a rigid recipe. It’s a technique. It’s about understanding how collagen transforms into gelatin. You don't need a culinary degree, but you do need patience. And maybe a big pot.
Why Your "Stock" Is Actually Just Weak Tea
Most people mess this up right at the start. They take a few bones, drown them in four gallons of water, and boil the life out of it for twenty minutes. Stop. That’s not how to make chicken stock from bones; that’s just making bone-flavored water.
True stock requires a high bone-to-water ratio. You want those bones barely covered. If they’re swimming in a vast ocean of liquid, the flavor will be diluted before you even turn on the stove. J. Kenji López-Alt, the wizard over at Serious Eats, has proven time and again that the ratio is everything. If you want that "lip-smacking" quality—that’s the gelatin—you need to maximize the surface area of the bones and keep the water level in check.
Also, stop boiling it. A violent boil emulsifies fat into the liquid, turning your stock cloudy and greasy. You want a "lazy bubble." One or two bubbles breaking the surface every few seconds is the sweet spot. This keeps the impurities from mixing back into the liquid, leaving you with something clear and clean.
The Raw vs. Roasted Debate
There are two schools of thought here.
- The White Stock: You use raw bones. This is the classic French fonds blanc. It’s delicate. It’s what you use for velvety cream soups or risotto where you want the chicken flavor to be pure and unadulterated.
- The Brown Stock: You roast the bones first. This is where the Maillard reaction happens. The sugars and proteins brown, creating a deeply savory, nutty profile. This is for gravy. This is for hearty stews.
If you’re using a leftover rotisserie carcass, you’re already in the "Brown Stock" camp. Those bones have already seen heat. If you're starting with raw backs or necks from the butcher, think about what you’re cooking tomorrow. If it’s a light spring soup, go raw. If it’s a mid-winter pot pie, roast those suckers at 400°F until they smell like heaven.

The Secret Architecture of Ingredients
Bones are the foundation, but the aromatics are the furniture. The classic mirepoix is two parts onion, one part carrot, and one part celery. It's a cliché for a reason. It works.
But don't just chop them and toss them in. Sautéing the vegetables for five minutes before adding the water can unlock fat-soluble flavors that boiling alone won't touch. And for the love of all things holy, leave the onion skins on if you want a beautiful amber color. The skins contain tannins and pigments that act like a natural dye.
Herbs and Spices
Keep it simple. You don't want a spice cabinet in your pot.
- Peppercorns: Use whole ones. Crushed pepper makes the stock cloudy and unpleasantly spicy.
- Parsley Stems: Don't waste the leaves here; save them for garnish. The stems have more concentrated flavor anyway.
- Bay Leaves: Just one or two. They provide a subtle, herbal bridge between the fat and the aromatics.
- Thyme: Fresh is best, but a pinch of dried works in a pinch.
Avoid "stinky" vegetables. Never put broccoli, cabbage, or cauliflower in your stock. They belong to the brassica family and will make your entire house smell like old gym socks. Trust me on this.
How to Make Chicken Stock from Bones: The Step-by-Step
First, get your bones. I prefer a mix. Backs and necks are cheap and loaded with cartilage. Cartilage equals gelatin. Wings are also fantastic because they have a high skin-to-bone ratio. If you can find chicken feet at a local Asian market or specialty butcher, buy them. They look terrifying, like tiny dinosaur hands, but they are the secret weapon of every pro chef. They are basically pure collagen.
Step 1: The Prep
Place your bones in a heavy-bottomed stockpot. If you're roasting them, do that first in a separate pan, then move them over. Pour in enough cold water to cover the bones by about an inch. Always start with cold water. It allows the proteins to dissolve slowly, which keeps the stock clear.

Step 2: The First Simmer
Bring it to a very slow simmer. As it heats up, you’ll see greyish-white foam rising to the top. This is "scum"—mostly denatured proteins. Skim it off with a wide spoon. It’s not harmful, but it makes the stock taste "muddy."
Step 3: Add the Aromatics
Once the skimming slows down, toss in your carrots, onions, celery, and herbs. Now, lower the heat to the absolute minimum. You want that "lazy bubble" we talked about.
Step 4: The Long Wait
How long? If you’re using a standard pot, 4 to 6 hours is the "goldilocks" zone. Anything less and you're leaving flavor on the table. Anything more than 8-10 hours and the vegetable flavors start to turn bitter and "cooked-out."
If you're using a pressure cooker like an Instant Pot, you can cheat. 45 minutes under high pressure followed by a natural release will give you a stock that tastes like it simmered all day. It's a game-changer for weeknight cooking.
The Strain and the Chill
Once the time is up, don't just dump the pot through a colander. You'll splash hot fat everywhere. Use a slotted spoon to remove the big chunks first. Then, pour the liquid through a fine-mesh sieve lined with cheesecloth or even a paper towel if you're desperate.
Cooling is a safety issue. Don't put a steaming hot pot of stock directly into your fridge. You'll raise the internal temp of the fridge and spoil your milk. Instead, fill your sink with ice water and set the pot in it. Stir it occasionally. Once it’s room temp, then move it to containers.

The next day, you’ll notice a layer of fat has solidified on top. This is the "schmaltz." Don't throw it away! It’s incredible for roasting potatoes or sautéing onions. You can scrape it off and keep it in a jar, or leave it there—it actually acts as a natural seal that keeps the stock fresh longer in the fridge.
Troubleshooting Your Stock
Sometimes things go sideways. If your stock didn't "gel" (meaning it’s still liquid when cold), you either used too much water or didn't simmer it long enough to break down the collagen. It’s still fine to use! It just won't have that rich mouthfeel.
If it tastes bitter, you might have burnt the vegetables during the roasting phase, or you left the herbs in for twelve hours. If it’s too salty... well, why did you add salt? Never salt your stock while it's simmering. You’re likely going to reduce the stock later in a recipe, and if you salt it now, it will become an inedible salt bomb later. Always season at the very end of whatever dish you’re making with the stock.
Storage Secrets
Stock lasts about 4 days in the fridge. That’s it. If you aren't going to use it, freeze it.
I like to freeze mine in silicone muffin tins or ice cube trays. Once they're frozen solid, pop them into a freezer bag. This way, if you just need a splash of stock to deglaze a pan, you don't have to thaw a whole quart.
Actionable Next Steps
Making your own liquid gold is a habit, not a chore. To get started today:
- Start a "Bone Bag": Keep a gallon-sized freezer bag in your freezer. Every time you roast a chicken or have leftover wing bones, toss them in.
- Veggie Scraps Count: Do the same for onion ends, carrot peels, and celery hearts. When the bags are full, it’s stock day.
- Buy a Fine Mesh Strainer: If you don't have one, get one. It's the difference between a gritty broth and a professional-grade stock.
- Label Everything: Frozen stock all looks the same. Write the date and whether it’s "Brown" or "White" on the bag. You'll thank yourself in three months.
Stop paying for water in a carton. Go buy some chicken wings or save that carcass from dinner. Your future soups are counting on you.
