Step 1

Season steak with salt and pepper. In the Instant Pot on sauté setting, heat olive oil and sear steaks for 2-3 minutes per side. Remove and set aside. In the same pot, sauté onions and garlic until soft. Add beef broth to deglaze the pot, scraping up browned bits.

Step 2

Return steaks to the pot and add Worcestershire sauce, and thyme. Seal the lid, cook on high pressure for 20 minutes, then allow 10 minutes natural pressure release.

Step 3

Remove steaks. Set Instant Pot to sauté.

Step 4

Melt butter in the liquid, then add cornstarch slurry (mix cornstarch with water) to thicken the sauce, stirring constantly until it reaches desired consistency. Adjust seasoning if needed.
