Instructions
Begin by setting your Instant Pot to 'Sauté' mode and adding the olive oil. Once the oil is shimmering, carefully place the beef cubes in batches, ensuring not to overcrowd the pot. Sear each piece until it develops a rich brown crust on all sides, which should take about 5-7 minutes per batch. Remove the browned beef from the pot and set aside on a plate.
Keeping the pot on 'Sauté', add the chopped onion and cook, stirring occasionally, until they turn soft and translucent, about 3 minutes. Add the minced garlic and continue to sauté for an additional minute, allowing the flavors to meld.
Introduce the sliced carrots, diced potatoes, and halved green beans to the pot. Stir the vegetables together and cook for about 3-5 minutes, ensuring they begin to soften slightly.
Return the seared beef to the pot and mix well with the vegetables. Pour in the beef broth, followed by the tomato paste, dried thyme, dried rosemary, the bay leaf, and Worcestershire sauce. Season generously with salt and freshly ground pepper. Stir everything together until fully combined.
Secure the lid of the Instant Pot, ensuring the steam release valve is set to 'Sealing'. Select 'Manual' or 'Pressure Cook' mode, adjusting the cooking time to 35 minutes at high pressure.
Once the cooking cycle is complete, let the pressure naturally release for 10 minutes. After this time, carefully switch the steam release valve to 'Venting' to manually release any remaining pressure.
For a thicker stew, remove approximately 1 cup of the stew broth from the pot. Mix this with the cornstarch and water in a separate bowl until smooth, then return this mixture to the pot while switching the Instant Pot back to 'Sauté' mode. Stir continuously until the stew thickens to your desired consistency.
Finally, remember to remove the bay leaf from the pot. Ladle the hearty beef stew into individual bowls and enjoy!
