Ingredients:
- 1.25 lb Sirloin Steak, sliced thin
- 1 Tbsp Olive Oil
- 1 large Yellow Onion, diced
- 8 oz Cremini Mushrooms, sliced
- 3 cloves Garlic, minced
- 1 tsp Dried Thyme
- 1/2 tsp Salt
- 1/4 tsp Black Pepper
- 4 cups Low Sodium Beef Broth
- 1 Tbsp Worcestershire Sauce
- 12 oz Medium Egg Noodles
- 1/4 cup Heavy Cream
- 1/2 cup Light Sour Cream
Instructions:
- Use the Instant Pot 'Sauté' function and heat the olive oil. Add the sliced mushrooms and sauté until deeply browned, about 5-7 minutes. Remove mushrooms and set aside.
- Add the sliced sirloin steak to the pot and sear in batches until browned on all sides, ensuring a crust forms. Remove the beef and set aside.
- Deglaze the pot with a splash of broth. Add the diced onion and sauté until softened, about 3 minutes. Stir in the minced garlic, dried thyme, salt, and pepper and cook for 1 minute until fragrant.
- Return the seared beef to the pot. Pour in the remaining beef broth and Worcestershire sauce. Ensure all browned bits are scraped up from the bottom.
- Place the medium egg noodles evenly over the beef/broth mixture. DO NOT STIR. Gently push the noodles down until mostly submerged.
- Seal the Instant Pot lid. Select Manual (Pressure Cook) and cook on High Pressure for 3 minutes. Perform a Quick Release (QR) once cooking is complete.
- Open the lid and stir the noodles and beef well. Stir in the reserved sautéed mushrooms and heavy cream until combined.
- Turn the Instant Pot to the 'Sauté' setting on Low. Bring the liquid to a gentle simmer for 2-3 minutes to slightly thicken the sauce. Turn off the heat.
- Stir in the light sour cream until the sauce is smooth and velvety. Taste and adjust seasoning if necessary before serving immediately.
