Ingredients

• 1½ pounds (680g) cremini mushrooms, cleaned and halved
• 4 garlic cloves, finely chopped
• ¼ tsp dried thyme
• ½ tsp dried oregano
• ½ tsp dried basil
• 2 bay leaves
• 1 cup (240ml) vegetable broth
• Salt and freshly ground black pepper, to taste
• ¼ cup (60ml) half-and-half
• 2 tbsp (28g) unsalted butter
• 2 tbsp chopped fresh parsley

Instructions

1. Directions
2. In the inner pot of your Instant Pot, combine the mushrooms, chopped garlic, thyme, oregano, basil, bay leaves, and vegetable broth. Season generously with salt and pepper and stir to combine.
3. Secure the lid and turn the pressure release valve to the “Sealing” position.
4. Select the “Manual” or “Pressure Cook” function and set the timer to 4 minutes at High Pressure.
5. When the cooking cycle is complete, carefully perform a Quick Release by moving the valve to the “Venting” position.
6. Once the float valve drops, remove the lid. Stir in the half-and-half and butter until the butter is fully melted and the sauce is creamy. Remove and discard the bay leaves.
7. Garnish with fresh parsley and serve warm.
