Instant Pot Pot Roast & Mashed Potatoes

In this recipe we will show you how to make Instant Pot pot roast and mashed potatoes all at once.  This saves so much time and really brings out amazing flavors.
Prep Time5 mins
Cook Time35 mins
Total Time40 mins
Course: dinner
Cuisine: American
Servings: 8

Ingredients

  • 3 pound beef chuck roast
  • salt to taste
  • pepper to taste
  • other seasoning to taste we love Trader Joe's African Smoke Seasoning
  • 2 tbsp olive oil
  • 1 cup marsala wine
  • 1 can 16 oz beef broth
  • 3 cloves garlic, chopped
  • 3 sprigs thyme
  • 1 cup baby carrots
  • 2 cups yellow onion, chopped into fourths
  • 6 large russet potatoes, peeled

Instructions

  • Pour olive oil into pan and heat on stove top at medium-high heat
  • rub salt, pepper & other seasoning to taste on beef chuck roast
  • brown pot roast in olive oil - about 5 minutes on each side.  Make sure and brown all 4 sides of the roast as this helps trap the flavor into the meat
  • add the remaining ingredients into the instant pot (except the potatoes) and gently stir ingredients together
  • add the pot roast to the center of the instant pot
  • place the instant pot cooking rack above the roast - use the high legs so that your rack doesn't touch the roast and other ingredients below.
  • place the peeled whole russet potatoes on the rack
  • cook on manual high for 35 minutes - make sure and follow your manufacturer instructions for heating and cooling your instant pot
  • Once complete if you want to make the juice into a gravy, strain all the juice from your instant pot, slowly add corn starch while stirring until you get the consistency desired

Notes

Most people use red wine with pot roast.  We tried it with marsala wine and the flavor was AMAZING!  It added a little sweetness to the gravy with a hint of marsala flavoring.  I highly recommend trying it!
