FAQ

Can I make this without an Instant Pot?

Yes! Sear the roast in a skillet, then toss everything in a slow cooker. Cook on low for 8–9 hours or high for 5–6 hours until tender.

Do I have to use pepperoncini? Is it spicy?

Nope! Pepperoncini add tang, not a ton of heat. You can use fewer peppers (or just some of the juice) for less zing. Not a fan? Try banana peppers, or just use extra broth and a splash of apple cider vinegar for tang.

What’s the best beef cut for Mississippi Pot Roast?

Chuck roast is classic because it gets super tender, but brisket, tri-tip, or even pork shoulder work well.

My sauce is too thin! How do I thicken it?

Mix a tablespoon of cornstarch with 2 tablespoons of cold water, stir into the hot sauce, and let it bubble for a few minutes to thicken.
