Why You’ll Love This Recipe

• “Dump and start”: Unlike some of my Instant Pot recipes, there’s no browning of meat necessary.

• Not salty: Like other Mississippi pot roast recipes using the packets.
• Fast: Minimal prep time and on your table in 2.5 hours, it’s faster than the oven or crock pot versions.

Ingredients for Instant Pot Mississippi Pot Roast

Mississippi roast in Instant Pot uses a handful of simple ingredients and seasonings that produce incredible flavor with a tangy kick. Here’s what you’ll need.

• Chuck roast: The best choice, second best is rump roast and third best is bottom round. I also tested eye of round roast, which is pictured, and it was OK, it’s a bit too lean to shred. A roast with some marbling is the best!
• Beef broth: Low sodium beef broth is best with beef. Use store-bought or make your own Instant Pot beef bone broth. Or if you have previously made vegetable broth or Instant Pot chicken broth that would work too.
• Soy sauce: Deepens the flavor of the gravy. You can use soy sauce or liquid aminos.
• Peperoncini: Whole or sliced. They aren’t overly spicy and add tang. Whole peppers are better because sliced peppers will disintegrate more during cooking but it’s OK.
• Peperoncini liquid: We add 1/4 cup of peperoncini juice for amazing flavor.
• Seasonings: A blend of garlic powder, onion powder, dried chives, dried dillweed, dried parsley, and black pepper adds the perfect amount of flavor and you can adjust to taste.
• Butter: I prefer unsalted butter to keep this recipe lower in sodium.
• Cornstarch: To thicken the gravy.
• Fresh parsley: Garnish each serving with fresh parsley.

Tips for Choosing the Best Cut of Beef

Instant Pot mississippi roast will be the most tender, flavorful pot roast with these helpful tips.

• Choose the right roast: Select a good cut of meat, so it comes out tender and shreds easily. Also be sure to buy not overly fatty chuck roast.
• Trim some fat: If it looks like there’s excess fat on the outer edge you can trim some off to help prevent a greasy roast. Keep in mind a little fat will flavor the roast and keep it juicy.
• Try more lean roast: I tried eye of round roast and it was a bit hard to shred more towards the center but not terrible and still tender. You can also cut it in 2 inch cubes before cooking. Also try sirloin tip roast.

Can I Add Vegetables?

Yes, make Mississippi pot roast in Instant Pot a complete one pot meal with the addition of veggies! To the pot, I would add only large chunks of potatoes and carrots, or baby potatoes and baby carrots. Be ready they will be very very soft.

Or wrap them in parchment paper like I do in my 8 quart Instant Pot when making Instant Pot pot roast. This will also work with a 10 quart Instant Pot.

If you’re using a 6 quart Instant Pot, I recommend cooking the veggies after so they’re not overcooked. Drop them into the pot after removing the meat and pressure cook on high pressure for 5 minutes. Quick release, remove veggies, and finish the recipe as instructed.

You can also add parsnip, sweet potatoes, diced tomatoes, or onion.

I wouldn’t recommend to add any other vegetables like green beans or broccoli because they will be mushy.

What to Serve with the Roast?

I served it with Instant Pot mushroom risotto because that’s what I made that day as well. I always love potatoes and gravy so Instant Pot baked potatoes, Instant Pot mashed potatoes, or Instant Pot potatoes are popular in our house.

Add shredded pot roast in sandwiches or buns, like beef dip sandwiches with some caramelized onions, roasted red onions or grilled onions.

Serve over egg noodles, or with Yorkshire pudding and vegetables like roasted butternut squash or zucchini tomato bake.

And finally, for a low carb side we love cauliflower mashed potatoes and cauliflower rice.
