Burger Patties

  • 1 lb grass-fed ground beef
  • 2 carrots, peeled
  • 1/4 onion
  • 1 clove garlic
  • 1 tsp. yellow mustard
  • Sea salt & black pepper, to taste

Portobello "Buns"

  • 4-8 portobello mushrooms, depending on whether you want open-faced or sandwiched burgers
  • 1 tbsp. avocado oil
  • Sea salt & black pepper, to taste

Easy Smoked Paprika Mayo

  • 3 tbsp. avocado oil mayo, I use Chosen Foods
  • 1/2 tsp. smoked paprika


Burger Patties

  • Add carrot, onion, garlic, yellow mustard, sea salt and black pepper into a food processor and process until ingredients are finely chopped.
  • In a bowl, combine ground beef with ingredients from food processor.
  • Form 4-5 burger patties using your hands. Once you've flatted the meat, press your finger into the center to form an indent in your patty (this will help cook the inside of the burger).
  • Cook burgers on stove top over medium heat, flipping occasionally. Cooking time will vary based on the thickness of the burger (~ 15 minutes). You can also cook your burgers on the BBQ.

Portobello Mushrooms

  • While burgers are cooking, remove stems from portobello mushrooms and place in a large stove top pan with oil.
  • Cover and cook over medium heat, flipping occasionally. Water from mushrooms should release into pan, preventing the mushrooms from burning. If there is not enough liquid, add a splash of white wine, lemon juice or water.
  • Once mushrooms have cooked for 10-minutes, remove lid and let any remaining juices cook off. Season with sea salt and black pepper.
  • Place cooked burger patties on top of portobello mushrooms, top with smoked paprika mayo (or other condiments/toppings) and close off with another portobello mushroom or leave it open-faced.

Smoked Paprika Mayo (optional)

  • Add mayo and smoked paprika into a small bowl and mix until ingredients are blended well.


If you're cooking the burger patties on the BBQ, feel free to cook the portobello mushrooms on the BBQ too.

    Jenn! This looks amazing! Quick question for you before I do it. Your ebook. Once I pay for it is it an app or do we access by log in information? I ask because I mostly use my iPhone.

    I look forward to hearing from you and I am sorry with my million questions!
