Made with veggies and beef stew meat, this Instant Pot vegetable beef soup only takes about an hour to cook but tastes like it's been slow cooking all day long!
Add olive oil to an Instant Pot and set to ‘sauté.’ Season beef with salt and pepper. Once the oil is shimmering, add the beef and brown on all sides, cooking for 10 minutes total.
Remove beef with a slotted spoon and set aside. Add onion, potato, celery, and thyme and cook for 5 minutes, or until the vegetables start to soften. Season with salt and pepper.
Add tomato paste and cook for 1 minute, or until it starts to caramelize on the bottom of the pot. Deglaze with the vegetable broth and cook for 2 minutes.
Add diced tomatoes, vegetable broth, and reserved beef to the pot and bring to a simmer. Once it reaches a simmer, hit cancel, then add the Instant Pot lid with the vent set to ‘sealing.’
Set to cook at high pressure for 25 minutes. When the cooking time is up, let the pressure release naturally for 15 minutes, then manual release any remaining pressure. Remove the lid.
Set the Instant Pot back to “sauté.” Add the frozen vegetables and let them cook for 5 minutes, or until heated through. Season to taste and serve.
Notes
Tip: Make a double batch of this beef soup to store in the freezer for nights when you don't have anything planned for dinner.
