Preheat your Instant Pot by selecting the Sauté mode.
Add the 1 tbsp. (0. 5 fl oz / 15ml) avocado oil and the 1. 5 lb (24 oz / 680g) sliced white mushrooms to the pot, sautéing them for exactly 5 minutes until they begin to soften.
Stir in the 1 cup (8 fl oz / 240ml) veggie stock, 1 tbsp. (0. 5 oz / 14g) chopped dill, 1 tbsp. (0. 5 oz / 14g) chopped rosemary, 1 tbsp. (0. 2 oz / 7g) sweet paprika, 0. 1 tsp. (0. 5g) salt, and 0. 1 tsp. (0. 5g / 0.18 oz) black pepper, mixing everything well to combine the flavors.
Cancel the Sauté function, secure the pot’s lid, and ensure the pressure valve is set to the sealing position.
Allow the Instant Pot to perform a Natural Pressure Release for exactly 10 minutes, then carefully manually release any remaining steam.
Remove the lid safely, give the mushrooms a final stir, and serve fresh.
