Even pot roast haters will become believers with this incredible pot roast recipe! It's also Paleo and Whole30 compliant.
- 2 tablespoons garlic-infused olive oil *
- 3-4 pound beef chuck roast
- 1 cup leek, dark green leaves only, finely chopped*
- 1 1/2 cups low FODMAP low sodium beef broth
- 2 tablespoons tomato paste
- 1 tablespoon coconut aminos
- 1 tablespoon fresh thyme (or 1 teaspoon dried thyme)
- 1 teaspoon kosher salt, plus more for sprinkling
- 1/2 teaspoon black pepper, freshly-ground, plus more for sprinkling
- 4 large carrots (about 1 pound), peeled and chopped, or 1 pound baby carrots
- 1 pound red potatoes, chopped into 1/2-inch pieces
- 1 cup king oyster mushrooms, halved lengthwise then sliced horizontally*
- Have the leek chopped and ready before starting; the remaining vegetables can be chopped while the roast is cooking.
- Press the "Sauté" button on your 6-quart Instant Pot, 8-quart Instant Pot, or comparable electric pressure cooker, and add garlic-infused olive oil. While the Instant Pot is heating up, dry roast well with paper towels. Sprinkle with kosher salt and freshly-ground black pepper.
- Once the display on the Instant Pot reads "Hot," using tongs, add roast to the pot and sear for 2 minutes on each long side and 1 minute on each short side until all sides are brown. Remove roast to a plate.
- Add leek and sauté for 2 minutes, stirring frequently so that it does not burn.
- Press "Cancel" on the Instant Pot. Add beef broth to deglaze the pot, wait 15 seconds, and scrape the bottom of the pot clean with a plastic spoon.
- Add tomato paste, coconut aminos, thyme, 1 teaspoon kosher salt and ½ teaspoon black pepper to the pot and stir. Put the roast back in the pot and scrape any juices that it left behind on the plate into the pot with a spatula (leave no flavor behind!!!). Close the lid of the Instant Pot and set pressure release valve to "Sealing." Press the "Meat" button and set timer for 50 minutes. While the roast is cooking, chop carrots, potatoes and oyster mushrooms.
- Once the cooking cycle has completed, quick release the pressure. Using a fresh set of tongs, carefully flip the roast over to the opposite side in the pot. Add the carrots, potatoes and mushrooms to the broth around the roast, being careful of hot, splashing broth. Use the tongs to gently push the vegetables as far down into the broth as possible.
- Close the lid of the Instant Pot and set pressure release valve to "Sealing." Press the "Pressure Cook" or "Manual" button and set timer for 3 minutes.
- Once the cooking cycle has completed, quick release the pressure. Carefully remove roast to a serving platter using tongs. Using a slotted spoon, remove vegetables to a serving vessel. Pour pan juices into a measuring cup or gravy boat and serve over the meat and potatoes.
- *If you're not concerned with FODMAPs, you can use regular olive oil and 4 cloves of minced garlic instead of the garlic-infused olive oil, a medium, sliced sweet or white onion instead of the leek, and white button mushrooms or other mushrooms of choice instead of king oyster mushrooms. View my post above for further instructions on how to incorporate these ingredients.
