Prepare Ingredients:
Dice onion, mince garlic, and cube beef (if needed).
Sear the Beef:
Set Instant Pot to sauté mode.
Heat oil until shimmering, season beef with salt and pepper, and sear in batches until browned. Remove beef and set aside.
Sauté Aromatics:
Add diced onion to the pot and sauté for 2–3 minutes until translucent.
Stir in minced garlic and cook for 30 seconds.
Deglaze Pot:
Pour in a splash of beef broth and scrape the bottom of the pot to release browned bits.
Combine Ingredients:
Return beef to the pot. Add beef broth, Worcestershire sauce, bay leaf, Italian seasoning, and thyme. Stir to combine.
Pressure Cook:
Secure lid and set valve to sealing. Cook on high pressure for 35 minutes, followed by a 10-minute natural release.
Thicken Gravy:
Switch to sauté mode. Mix cornstarch with water to make a slurry, then stir into the pot. Simmer for 3–5 minutes until gravy thickens.
Serve and Garnish:
Remove bay leaf and thyme sprig. Serve beef tips and gravy over rice, noodles, or potatoes. Garnish with fresh parsley.
