Why use portobello mushrooms as a pizza base?

  • Low in Calories: Portobello mushrooms are significantly lower in calories compared to traditional pizza crusts, making them a great option for calorie-conscious eaters
  • Rich in Nutrients: They provide essential vitamins and minerals, including B vitamins (such as riboflavin and niacin), selenium, and potassium, which support overall health
  • High in Antioxidants: Portobello mushrooms contain antioxidants that help combat oxidative stress by boosting the immune system
  • Low in Carbohydrates: A perfect low-carb alternative for those following ketogenic or low-carb diets
  • Source of Fibre: They are rich in dietary fibre, which promotes digestive health and helps keep you feeling full longer
  • Plant-Based Protein: While not as high in protein as meat, portobello mushrooms still contribute a decent amount of plant-based protein, supporting muscle health and recovery
  • Anti-Inflammatory Properties: Certain compounds in mushrooms may help reduce inflammation in the body
  • Versatile Flavour: The meaty texture and umami flavour of portobello mushrooms provide a satisfying base for pizza, enhancing the overall taste without the added carbs
  • Gluten-free: If you follow a gluten-free, grain-free, or celiac diet, portobello mushrooms are a healthy (and easy!) pizza crust alternative

Pro tips

  1. Since you don’t want the mushroom cap to get soggy when baking, cooking them on a perforated pizza pan allows the moisture to escape
  2. You will want to remove the stems from the mushroom and the gills using a spoon. These are the little flaps the surround the inside of the mushroom cap. They are 100% edible, but you might find that they taste a little earthy, so remove them at your discretion!
  3. If you choose to add any meats to your pizza, be sure it is thoroughly cooked first as there won’t be enough time for meat to cook in the mushroom cap (in this recipe)
  4. Wondering what kind of mushrooms work best for this recipe? You are looking for large portobello mushrooms. They are often bundled up into pairs, and also sold individually. Try to find the biggest ones you can so you can fit all the great pizza fillings
  5. If you are following the Metabolic Balance program, just use one protein (meat OR cheese)
