Instant Pot® Pork Roast with Cauliflower Gravy

Place cauliflower, water, onion, celery, and garlic in the bottom of a multi-functional pressure cooker (such as Instant Pot®). Place pork roast on top and season with salt and pepper. Close and lock the lid. Select high pressure according to manufacturer's instructions; set timer for 60 minutes. Allow 10 to 15 minutes for pressure to build.

Release pressure carefully using the quick-release method according to manufacturer's instructions, about 5 minutes. Unlock and remove the lid. Transfer pork to a baking dish and transfer cooked vegetables and broth to a blender.

Preheat the oven to 400 degrees F (200 degrees C).

Bake pork in the preheated oven while you prepare the gravy, allowing the fat to render and edges to crisp up.

Cover the blender and hold lid down with a potholder; pulse a few times before leaving on to blend vegetables until smooth.

Turn the Instant Pot® to the Saute function. Add coconut oil and mushrooms and cook until soft, 3 to 5 minutes. Pour in blended vegetables and continue to cook until gravy has thickened, 5 to 7 minutes.

Remove pork from the oven and shred with two forks. Serve with mushroom gravy.
