Canning Mississippi Pot Roast is one of the easiest ways to turn a comfort-food favorite into a shelf-stable meal you’ll actually use. This pressure-canned version keeps all the tangy, savory flavor without the crockpot babysitting or weeknight chaos.

Let’s get this out of the way up front: this is not Pinterest-perfect pot roast. There’s no butter stick floating around in here, no crockpot fantasy, and no pretending this is complicated.

This is Mississippi pot roast you can open on a Tuesday when life is crazy and people are hungry.

While You’ll Love This Recipe

You’ll love this because it takes an all-day comfort food and turns it into a shelf-stable, ready-to-eat meal that can be on the table in under 30 minutes.

That said, here are a few things to keep in mind:

• This isn’t a “dump everything in the crockpot and forget it” situation. Instead, this is preserving a meat-based meal safely so you can eat it later without wondering if it’s going to kill you.
• If your version of Mississippi pot roast includes butter, cream cheese, or thickeners, those get added when you open the jar, not before canning.
• The flavor deepens as it sits. If you open it right away, it’s good. If it’s been on the shelf a few months, it’s better.
• This is flexible food. Eat it as-is, shred it, turn it into sandwiches, pot pie filling, or freeze leftovers after opening.

You’re not locking yourself into one meal, you’re buying yourself options.

What I Used

In the jars:

• Stew meat (I used beef... venison, pork, or chicken all work; the process is the same)
• Onion
• Sliced pepperoncini peppers (whole works too)
• Minced garlic

For the liquid:

• 8 cups water
• 2 tablespoons + 1 teaspoon ranch seasoning
• 1 packet au jus gravy mix
• 2 tablespoons red wine vinegar
• 2 tablespoons pepperoncini liquid

Yes, I used packets. No, I don’t feel bad about it. You can absolutely use homemade if that's your jam, no judgement.

Jar Assembly (Raw Pack)

This is how I built each jar:

1. In the bottom of the jar, I added:
   • Minced garlic
   • About ½ a sliced onion
   • ¼ cup sliced pepperoncini peppers
2. I filled the jar the rest of the way with stew meat, leaving 1 inch headspace.
3. I mixed the liquid ingredients together, poured it over the meat, and:
   • De-bubbled aggressively (because trapped air is not your friend)
   • Topped off with liquid as needed to maintain 1 inch headspace

That’s it. No browning. No drama.

Pressure Canning

• Quarts: 90 minutes
• Pints: 75 minutes
• Pressure: 10 lbs (for my altitude)

Adjust for your altitude like a responsible adult.

Let the canner cool naturally. No forcing it. No shortcuts.

A Few Important Notes (Read These)

• This is pressure canning only. Meat doesn’t get water-bathed. Ever.
• I did not add butter or oil. You can add that when you pop open the jar and heat it up.
• You don’t have to add onions, peppers, or garlic, but they’re all approved additions and they make it taste like actual Mississippi pot roast instead of sadness.
• You can raw pack beef without added liquid, but in this case the seasoned liquid is doing the heavy lifting flavor-wise, so it’s worth it.
• Make sure you debubble really well, it can be difficult depending on how tightly the jar is packed, but it's essential.

How To Use Canned Mississippi Pot Roast

Open jar. Pour out contents. Heat until nice and steamy. Serve over mashed potatoes, rice, or egg noodles.

It’s rich, tangy, and stupidly comforting... the kind of food that makes you feel like you planned better than you actually did.

Final Thought

This isn’t about perfection. It’s about feeding your people with what you have, in a way that makes sense for real life.

If you want to brown meat and slow cook all day, great. If you want shelf-stable meals that save your sanity later, this works fantastically well.
