Instructions
Prepare the Instant Pot: Set your Instant Pot to the Sauté mode and allow it to heat up. Add the olive oil and swirl to coat the bottom of the pot.
Brown the Beef: In batches, add the thinly sliced beef sirloin to the pot. Sear for about 2-3 minutes on each side until browned. Once browned, remove the beef from the pot and set it aside on a plate.
Sauté Onion and Garlic: In the same pot, add the chopped onion and minced garlic. Sauté for 2-3 minutes, stirring frequently, until the onion becomes translucent and fragrant.
Cook the Mushrooms: Add the sliced mushrooms to the pot. Continue to sauté for about 3-4 minutes until the mushrooms have released their juices and are tender.
Combine Ingredients: Pour in the beef broth and add the Worcestershire sauce, Dijon mustard, and dried thyme. Return the browned beef to the pot. Season the mixture with salt and pepper, stirring everything together to combine.
Pressure Cook: Close the lid securely on the Instant Pot. Ensure the pressure valve is set to sealing, then select Manual mode and cook on high pressure for 10 minutes.
Release Pressure: When the cooking time is up, carefully do a quick release of the pressure by turning the valve to venting. Use caution, as steam will escape.
Thicken the Sauce: After the pressure has fully released, open the lid and stir in the sour cream and cornstarch mixture. Switch the Instant Pot back to Sauté mode and cook for an additional 2-3 minutes, stirring continuously, until the sauce has thickened to your desired consistency.
Cook the Noodles: While the stroganoff is thickening, prepare the egg noodles in a separate pot according to package instructions. Once cooked, drain the noodles and set them aside.
Serve: Ladle the hearty beef stroganoff sauce generously over the cooked egg noodles. Garnish with a sprinkle of fresh chopped parsley for an added touch of color and flavor.
Notes
For an elegant presentation, serve the stroganoff in shallow bowls with a sprig of fresh parsley on top.
