Who doesn’t love a good pot roast? I love that you can throw it in the slow cooker or Instant Pot and forget about it. I was first introduced to Mississippi Roast, pot roast with butter, pepperoncini peppers, ranch seasoning and au jus seasoning, by a coworker. Don’t get it wrong, it tasted amazing! I wasn’t be biggest fan, though, that it called for a whole stick of butter!

In an effort to lighten up this dish, I tried making it without any butter and didn’t miss it at all. Rather than use powdered au jus seasoning, I used what I had on hand: a packet of onion soup mix. Guess what? It tasted amazing. You still get an amazingly flavorful “gravy” to spoon over melt-in-your-mouth pot roast.

Why Chuck Roast?

Chuck roast is the perfect cut for slow cooking because it falls apart and turns to butter. It also happens to be one of the more affordable cuts of beef roast. You can also use pork butt for this recipe as an even more budget-friendly option.

Freezer Meal Option

This recipe is perfect for freezer meal prep. Combine all of the ingredients in one of these 64 oz freezer containers and freezer. When ready to cook, thaw in your fridge overnight. (It’s ok if it is still frozen when added to your slow cooker or Instant Pot.) Cook as directed.

How to Serve It

I usually serve this with mashed potatoes and roasted carrots. It would also make perfect beef sandwiches. Pile it up on a hoagie roll and top with provolone cheese. Yum!
