The Freezer Bag System—Why I Haven't Bought Broth in Years

March 18, 2026

A gallon bag in your freezer is all it takes to turn kitchen “waste” into quarts of broth that beats anything from a store.

The Story

I used to throw away bones like everyone else. Steak night? Bones in the trash. Roast chicken? Carcass in the garbage. Thanksgiving turkey? Straight to the bin.

Then I did the math.

A quart of decent bone broth at the grocery store costs $5-7. The premium stuff runs even higher. Our household uses 2-3 quarts a month for soups, rice, and cooking. That is $10-21 a month, or $120-250 a year—on something I can make for free from bones I am already throwing away.

The bones were already paid for. They were part of the cost of the meat. I was literally paying for them, then putting them in the garbage and going to the store to buy broth made from someone else’s bones.

Once I understood that, I stopped. I put a gallon freezer bag in my freezer and started saving bones. Steak bones go in. Chicken carcasses go in. Turkey bones go in. When the bag is full, I make broth.

That was years ago. I have not bought broth since.

Key Details

Time Investment: 15 minutes active work | Cost: $0 | Yield: Varies by bones

Sustainability Note: Every batch of homemade bone broth represents bones that would have been landfilled, packaging you did not buy, and money that stayed in your wallet. The bones were already paid for when you bought the meat.

The System

This is not complicated. It requires exactly one thing: a gallon freezer bag in your freezer.

What Goes In

Chicken bones: After roasting a whole chicken, the carcass goes in the bag. Wings, drumsticks, thighs—any bones left after eating.

Turkey bones: After Thanksgiving or any time we roast a turkey, the entire carcass goes in. One turkey carcass can fill most of a bag on its own.

Beef bones: Ribeye bones, T-bone bones, any bone from a bone-in steak or roast. We also buy beef bones specifically for broth—after simmering for 24 hours, the large beef bones go to the dogs. Double duty: rich broth for us, then a treat for them. (Note: Only give dogs bones appropriate for their size—large beef bones are generally safe after cooking, but cooked poultry bones can splinter and should never be given to dogs.)

Smoked meat bones: This is the secret weapon. If you smoke meat—chicken, turkey, brisket—save those bones separately if you can. Smoked bone broth has a depth that is genuinely special.

I keep separate bags for chicken, turkey, and beef bones. Each type makes a different broth with its own flavor profile, and keeping them separate means I know what I am getting when I make a batch.

What Stays Out

Pork bones: Pork broth is a legitimate thing—it is popular in Asian cooking (ramen, pho) and Mexican stews. However, I do not save pork bones for general-purpose broth because the flavor is distinct and does not blend well with chicken or beef. That said, I do make tonkotsu (pork bone broth) specifically for ramen—that is a different purpose with its own dedicated recipe.

Fish bones: Fish stock is a different thing entirely and requires a different approach.

Bones with heavy sauce: If the bones are covered in BBQ sauce or heavy seasoning, they will flavor the entire batch. Save them only if you want that flavor throughout.

The Process

  1. Eat the meat. Enjoy your steak, chicken, or turkey.

  2. Save the bones. Scrape off any meat you want to keep, then put the bones in the freezer bag. They can go in warm—the freezer will handle it.

  3. Repeat. Every time you have bones, they go in the bag.

  4. When the bag is full, make broth. Dump everything into a slow cooker, cover with water, add vinegar, and let it simmer all day.

That is it. No special equipment. No complicated technique. Just a freezer bag and patience.

Why This Works

The Bones Are Already Paid For

When you buy a whole chicken, you pay for the entire bird—meat and bones. When you buy bone-in steaks, you pay for the bone weight. That cost is baked into the price.

Most people throw away 20-30% of what they paid for. Saving the bones and making broth extracts value from something you already own.

Slow Cooking Extracts Everything

Bones contain collagen, minerals, and flavor compounds that only release with long, slow cooking. A slow cooker set to LOW for 8-24 hours extracts all of it. The broth gels when refrigerated—that gel is collagen, and it is the sign of properly made bone broth.

Homemade Beats Store-Bought

Store-bought broth is thin. It is oversalted. It tastes industrial because it is—made in factories with efficiency, not flavor, as the goal.

Homemade bone broth has body. It has depth. It has the actual flavor of the animals it came from. There is no comparison.

Pro Tips

Add your vegetable scraps. I keep two freezer bags—one for bones, one for vegetable scraps. When I make bone broth, I add the veggie scraps too. The vegetables add complexity and mean I am using two “waste” streams in one pot.

The vinegar matters. Adding 1/4 cup of apple cider vinegar or white vinegar helps extract minerals from the bones. You will not taste it in the finished broth.

Smoked bones are special. If you smoke meat, those bones make the best broth. The smokiness infuses into the liquid and creates something genuinely unique.

Gel is good. If your broth solidifies into gel when refrigerated, you did it right. That is collagen. It liquefies when reheated.

Strain well. Use a jelly bag or fine-mesh strainer. Nobody wants gritty broth.

Label everything. “Chicken broth - Jan 2026” prevents mystery containers in your freezer or unlabeled jars in your pantry.

The Math

Store-bought broth: $5-7 per quart Household monthly usage: 2-3 quarts total Annual cost if buying: $120-250

Homemade bone broth: $0 (bones already paid for) Time investment: 15 minutes active, 8-24 hours passive Annual savings: $120-250

Plus: better flavor, no packaging waste, no additives or preservatives.

What NOT to Do

Do not throw away bones. Every bone in the trash is money wasted.

Do not boil vigorously. A gentle simmer extracts flavor. Hard boiling makes broth cloudy and can create off-flavors.

Do not skip the vinegar. It helps extract minerals. This is not optional.

Do not can broth with root peels. If your broth includes unpeeled carrot or parsnip scraps, use it immediately or freeze it. USDA guidelines require peeled vegetables for pressure canning.

Storage Options

Refrigerator: Up to 5 days in a sealed container

Freezer: Up to 6 months. I freeze in quart containers for soups and in ice cube trays for small amounts (deglazing pans, cooking rice).

Pressure canning: For shelf-stable storage up to 1 year. Broth MUST be pressure canned—water bath canning is not safe for broth. See NCHFP meat stock canning instructions for current processing times and pressures.

The Real Benefit

This is not about being a perfect zero-waste household. This is about recognizing that you are already paying for bones and then throwing them away and buying broth made from someone else’s bones.

Once you see it, you cannot unsee it.

A gallon freezer bag costs about 8-10 cents (bought in bulk). Filling it costs nothing—you are saving what you would otherwise discard. Making the broth costs nothing but time, and most of that time is passive.

The result is quarts of rich, flavorful broth that beats anything from a store. Free, better, and made from something you used to throw away.

Start tonight. Save the bones from dinner. Put a bag in your freezer. See how fast it fills up.

Quick Reference

The System:

  1. Keep a gallon freezer bag in your freezer
  2. Add bones after every meal (chicken, turkey, steak)
  3. When bag is full, dump into slow cooker
  4. Add water, vinegar, and vegetable scraps
  5. Cook on LOW for 8-24 hours
  6. Strain through jelly bag
  7. Refrigerate, freeze, or pressure can

What to Save (in separate bags):

  • Chicken carcasses and bones
  • Turkey carcasses and bones
  • Beef bones (steaks, roasts, bones cooked for dogs)
  • Smoked meat bones (the best)

What to Skip:

  • Pork bones (different flavor profile)
  • Fish bones (different technique)
  • Heavily sauced bones (will flavor entire batch)

Expected Results:

  • Rich, gelatinous broth
  • Zero cost (bones already paid for)
  • Better flavor than store-bought
  • $120-250 annual savings

You are already paying for the bones. Stop throwing them away and buying someone else’s broth. A freezer bag and a slow cooker are all you need to keep that money in your pocket.
