Ingredients

• 1 lb / 450g beef shoulder roast, cut into bite-sized pieces
• 1 cup / 70g Cremini mushrooms, thinly sliced
• ½ cup / 120ml heavy cream
• 1 small red onion, diced
• 1 tbsp / 14g butter
• 2 cups / 475ml beef broth
• Spices
• 1 tsp salt
• 1 tsp dried thyme, ground
• ½ tsp white pepper, ground
• 1 tsp garlic powder

Instructions

1. Directions
2. Start the Mushroom Sauce: Set your Instant Pot to the “Sauté” function. Once hot, melt the butter and add the sliced cremini mushrooms and diced red onion. Sprinkle with salt and thyme, and cook for 10 minutes, stirring occasionally, until the mushrooms are softened and browned.
3. Make it Creamy: Pour the heavy cream into the pot with the mushrooms. Bring the mixture to a boil and then reduce to a simmer for 5 minutes, allowing it to thicken slightly.
4. Blend to Perfection: Carefully transfer the mushroom mixture to a food processor or blender. Pulse until the sauce is completely smooth and creamy. Set aside.
5. Cook the Beef: Add the beef pieces to the now-empty Instant Pot insert. Season with white pepper, garlic powder, and a pinch of salt. Pour in the beef broth. Secure the lid, set the valve to the “Sealing” position, and cook on “High” pressure for 15 minutes.
6. Finish and Serve: When the timer finishes, perform a quick pressure release. Once the pin drops, carefully open the lid. Transfer the tender beef to a serving plate and lavishly pour the creamy mushroom sauce over the top. Serve hot.

Pro Tips

• For a deeper, richer flavor, sear the beef pieces in the Instant Pot on “Sauté” mode before adding the broth. Remove the beef, deglaze the pot with a splash of broth, and then proceed with the pressure cooking step.
• If your sauce isn’t as thick as you’d like, create a slurry by mixing 1 teaspoon of cornstarch with 2 teaspoons of cold water. Whisk it into the sauce on “Sauté” mode until it thickens.
• This dish pairs beautifully with cauliflower rice or zucchini noodles for a low-carb meal, or serve it over creamy mashed potatoes or egg noodles for a heartier option.
