I am not a huge meat person. I like meat in things. But I don’t really care for a big hunk of meat as the main thing. You get what I’m saying? Well, this roast may have changed my mind. It was so flavorful with the onions and gravy that I couldn’t stop eating it. My son and I both loved it when it first got done and when my daughter and Greg tried it as leftovers they loved it too.

You’ll start this roast by browning each side. This is an extra step, I know. But it is worth it, in my opinion, because it adds a depth of flavor. After the roast has a little color you’ll toss some thinly sliced onions into the pot with a bit of baking soda. This helps with the maillard reaction (the browning process of onions that gives it that sweet, golden flavor). After a couple minutes the onions will start releasing juices and turning yellow. You’ll add in vinegar, Worcestershire, some seasonings and a can of tomato sauce with the beef. Then it’s time to pressure cook.

My roast was a pretty thin flat roast. It was about 2 inches thick at its thickest section. I decided to use a 60 minute pressure cook time. But if you have a roast that is thick in the middle then you’ll want to add 10 extra minutes per inch of thickness. So if you have a roast that’s 4 inches thick pressure cook for 80 minutes. And, as always, with roasts you’ll want to use a natural pressure release so that the meat stays nice and tender.

I’ll tell you another trick to get nice tender roast. You can quarter the roast. This helps each piece get more sauce on it too. I didn’t quarter my roast this time around but I have a lot in the past and have always liked how they turn out.

Description

Tender pieces of chuck roast with caramelized onions and gravy. This roast is addicting!


Ingredients

Scale
  • 1 Tbsp canola or olive oil
  • 2 pound chuck roast
  • 2 medium onions, halved and sliced
  • 1/2 tsp baking soda
  • 1 cup beef broth
  • 1 Tbsp minced garlic
  • 1 Tbsp red wine vinegar
  • 1 Tbsp Worcestershire sauce
  • 1 (8 oz) can tomato sauce
  • 1 tsp kosher salt
  • 1 tsp black pepper
  • 1/4 tsp dried thyme
  • 2 tsp parsley
  • Cornstarch

Instructions

Instant Pot Instructions:

  1. Turn Instant Pot to saute setting. When display says HOT add in the oil. Brown the roast on each side for about 4 minutes. Remove the roast and place on a plate. 
  2. Add in the onions and baking soda. Toss until the onions start to release moisture and they turn yellow (3-4 minutes). Pour in the broth and scrape bottom of pot so that nothing is sticking.  
  3. Place the roast on top of the onions. Pour garlic, vinegar, Worcestershire, tomato sauce, salt, pepper, thyme and parsley on top of the roast.
  4. Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 60 minutes for a roast that is 2 inches thick. If your roast is thicker add 10 minutes per extra inch of thickness. When time is up let the pressure release naturally for 15 minutes then release any remaining pressure by moving valve to venting. 
  5. Place the beef on a cutting board. Use a colander or a slotted spoon to separate onions from juices and move them to a platter. 
  6. Thicken the juices remaining in the pot with a cornstarch slurry. Turn your Instant Pot to the sauté setting. In a small bowl stir together 2-3 Tbsp of cornstarch with 3 Tbsp of water, until smooth. Then pour the mixture into the Instant Pot. The cornstarch mixture will thicken up contents of pot quickly. Turn off Instant Pot once gravy is thickened.
  7. Slice or shred beef and serve with the onions and gravy. 

Slow Cooker Instructions: 

  1. Add onions, broth, roast, garlic, vinegar, Worcestershire, tomato sauce, salt, pepper, thyme and parsley into slow cooker.
  2. Cover and cook on low for 8-10 hours. Place the beef on a cutting board. Use a colander or a slotted spoon to separate onions from juices and move them to a platter. 
  3. Thicken the juices remaining in the pot with a cornstarch slurry. Turn slow cooker to high. In a small bowl stir together 2-3 Tbsp of cornstarch with 3 Tbsp of water, until smooth. Then pour the mixture into the slow cooker. Let the sauce thicken up for 10-20 minutes. 
  4. Slice or shred beef and serve with the onions and gravy.

    Everything came out great and my boys loved it! What ideas might you have with the leftover tomato gravy?

    Followed exactly as the instructions said. I wasn’t thrilled, it was okayyy but I wouldn’t make it again. I agree with Robin that the flavor was meh and the onions disappeared. On that note I think calling it french onion is a huge stretch since it has tomato sauce. I knew that going in but was being optimistic :/

    Thanks for a great recipe.

    Made it tonight. A little disappointed. Followed it to a “t”. Not as flavorable as i hoped. Onions disintegrated. Maybe next time i would add more.
    Gravy just ok. Had better success with other recipes of yours.

      I bet that would be okay. It will be a little drier because less fat but slather in the sauce and should be okay.

    Another excellent recipe! I had 2 large pieces of chuck roast that were about 1″ thick, so I cut back on the cooking time to 40 minutes and it was perfectly fall-of-the-fork tender. I served with mashed potatoes and fresh green beans. So flavorful and delicious! Thank you, Karen!

    I’m new to roasts in the IP though I’m confident making everything else in it. My chuck roast is about 3 pounds and I’d likely quarter it. It being more meat overall than you tested, does that increase cooking time slightly?

    Reply
    • Karen says

      April 12, 2021 at 12:43 pm

      If it’s cut into quarters I would use the same cooking time. Should be fine. The way you decide how long to cook something is by thickness. So if it’s not as thick it should be fine.

    I love how easy this recipe is for such amazing results. Delicious! I made it with parmesean bacon smashed potatoes and roasted asparagus. It reminded me of Sunday dinner at grandma’s house. Thank you!

      This is my opinion, but my Instant Pot produced a far superior beef roast compared to my Crock Pot. I’ve never had a more tender, tasty roast.
      I set my Instant Pot to saute spray with a little Pam and brown my roast. Add 1/2 cup of beef broth scrape the bits off the bottom. Put the roast back in. At this point I add 1 packet each, dry Italian salad dressing mix, dry ranch dressing mix and 1 packet brown gravy mix. Add about 1 to 2 cups of water. Replace cover and set manual for 45 minutes. Let release naturally for 10 minutes, then release the rest of the pressure. Make a slurry of corn starch and water. Remove beef add slurry to Instant Pot, set on saute cook just until gravy has thickened. This makes a delicious gravy. If it’s too salty add water.

    Followed the recipe exactly except… used pork roast! Turned out great. No change to cooking time.
    Was hunting in the freezer for the chuck roast I know is there (but hiding) and came across a pork sirloin roast (one of a Costco 4-pk) and decided to try that. Was still a bit cold/frozen in the center by cooking time but browned up fine and cooked perfectly.
    Served roast over egg noodles with lots of sauce. And side of broccoli (with sauce!). A keeper. Thanks!

        yes I did. considered using less time but since I wasn’t sure if pork was completely thawed or not decided to just use 60min. Perfect.

    I’ve been watching the March Madness College Basket Ball and eating Instant Pot meals while I watch TV. Two or Three days ago I fixed the “Meatloaf Melts” and then two days later I fixed the ‘Church Supper Spaghetti” . Today my wife told me that I have to start eating the left overs. I love left overs, so no problem there. My next meal with my TV watching buddies I plan cooking the “French Onion Pot Roast”.

    The baking soda helps the onionsturn brown better and faster and also helps with the texture of the onions
