Onion Mushroom Gravy

If you are looking for a truly comforting game-changer gravy then you’ve come to the right place! This has been our fam-favorite gravy for years. Don’t worry that there’s no meat sediment (this gravy is actually vegan!) or that it has no booze in it – I promise you that you won’t miss either! With its depth of flavor, umami (thanks to the vitamin B-rich nutritional yeast) and traditional warming herbs this gravy goes with just about everything! Definitely a winner when it comes to the holidays, as we love teaming it with my Cauli-Mash. I hope you enjoy it as much as we do!

Prep time


Cooking time



Makes Approx. 1½ Cups Gravy


  • 360g 1½ Cups Vegetable Broth

  • 210g 3 Large Portobello Mushrooms, thinly sliced & chopped

  • 70g ½ Cup White Onion, minced

  • 36g 2 Tbsps Tamari, or Coconut Aminos

  • 20g 2 Tbsps Nutritional Yeast Powder

  • 15g 1 Tbsp Avocado Oil

  • 10g 1½ Tbsps Arrowroot Flour 

  • 1g 2 tsp Dried Italian Herbs

  •   Fresh Cracked Black Pepper to taste


  • On the stove on low-medium heat in a medium saucepan, heat up the avocado oil. Add in the onion and cook for 3 minutes with the lid on while stirring occasionally.
  • Add in the mushroom and dried italian herbs. Stir continuously for 1 minute. 
  • Add in the broth and tamari. Bring to a gentle simmer.
  • Add in the nutritional yeast and pepper to taste.
  • In a medium bowl, take out ½ Cup of the hot gravy liquid and sift in the arrowroot flour. Make a paste with no clumps. Add this mixture back into the gravy. Continuously stir until a thick consistency is reached. Approx. 1 -2 minutes. Remove from the heat.
  • Serve warm. We love to pair this gravy with my Roasted Whole Herbed Chicken and my Cauli-Mash.


  • Storage: Gravy will keep well in a glass airtight sealed container in the refrigerator for up to a week.
