What You Can (And Can’t) Add to Canned Meat
One of the most common questions people have once they start canning meat is whether they can modify the recipe — add seasonings, change the liquid, throw in some vegetables. The short answer is: some things are fine, some things aren’t, and the distinction matters more for meat than for almost anything else you can.
Here’s what you can and can’t do, and why.
Why Meat Recipe Modifications Are a Bigger Deal Than Fruit or Jam
When you’re making jam, adjusting the sugar or swapping one berry for another has a relatively limited safety impact. The high acid content and the water bath process give you a reasonable margin.
Meat is different. Pressure canning recipes are carefully developed and lab tested to ensure that heat reaches the center of the jar to destroy dangerous bacteria like Clostridium botulinum. The density, fat content, and composition of what’s in the jar directly affects whether heat penetrates adequately all the way through during processing. Adding something that changes the density or fat content changes how heat moves through the jar — and unlike undercooking a roast, the consequences of undercooking a pressure-canned jar of meat aren’t visible until someone gets sick.
This isn’t about being overly cautious. It’s about the fact that botulism toxin can be present in a jar that looks, smells, and tastes completely normal.
What You Can Safely Add or Change
Salt. You can add it, reduce it, or leave it out entirely. Salt in home canning meat recipes is always listed as optional — it’s for flavor only, not preservation. Salt adds flavor, but it is not necessary for preservation. Use it, skip it, adjust the amount — all fine.
The type of liquid. You can generally use water, broth, or meat drippings interchangeably as the added liquid in hot-packed meat recipes. These have similar densities and don’t meaningfully affect heat penetration. Tomato juice is also used in some tested recipes and is acceptable where called for.
Basic dry herbs and spices. A bay leaf in a jar of beef, some peppercorns, dried thyme — small amounts of dry seasonings added to the jar are generally considered acceptable. They don’t change the density or composition of the contents in a way that affects processing safety. What you want to avoid is loading up jars with large quantities of anything that could affect consistency.
Which cuts of meat. Within a category — say, boneless chicken — you can generally use different cuts interchangeably as long as you’re following the correct processing time for that meat type and jar size. Switching from chicken thighs to chicken breast doesn’t require a different tested recipe.
What You Cannot Safely Add
Thickeners — flour, cornstarch, rice, pasta, or any starch. Do not add noodles or other pasta, rice, flour, cream, milk, or other thickening agents to home canned soups. This applies equally to canned meat. Thickeners change the density of the contents significantly and slow heat penetration — what looks fully processed on the outside may not have reached safe temperature at the center. If you want a thickened stew or soup, add the thickener after opening the jar when you’re reheating it for a meal.
Dairy — milk, cream, butter, cheese. Not tested, not safe for home canning. Dairy proteins break down unpredictably under pressure canning temperatures and can interfere with safe processing.
Extra fat. Adding extra fat that is not part of the recipe can pose safety risks. Excess fat can interfere with heat transfer inside the jar during processing, preventing the food from reaching the temperatures needed to destroy bacteria. Fat can cause seal failures. Trim visible fat before packing and don’t add oil, lard, or butter.
Cured, brined, or smoked meats. There is no safe approved process for home canning cured, brined or corned meats. Ham, bacon, corned beef — none of these have tested home canning processes. Store them in the freezer or use commercially canned versions.
Untested vegetable combinations in large amounts. Adding a handful of onion or garlic to a jar of chicken is one thing. Building a full stew with multiple vegetables packed densely into a jar is different — the density and composition matter. For combination recipes like meat with vegetables, use a specifically tested recipe for that combination rather than improvising.
The Rule That Covers Everything
If a modification changes the density, fat content, or pH of what’s in the jar in any meaningful way, it’s not a safe modification for pressure canned meat. If it’s purely about flavor and doesn’t change the composition — salt level, a dry herb, which cut of beef — it’s generally fine.
Never can meat products or combination foods for which you do not have research-based processing times. A safe canning time cannot accurately be determined at home.
When in doubt, freeze it instead. Freezing is always a safe alternative for anything you’re not confident about canning safely.
One More Step That’s Worth Doing Every Time
When ready to serve, boil canned meat and poultry for 10 minutes before tasting, even if it looks and smells all right. This is an extra safety measure that destroys any botulism toxin that might be present even in properly processed food. It’s a habit worth building regardless of how careful you were during processing.
