Tonight I was in the mood to grill out burgers. Since we can’t eat bread I love to make these Paleo AIP Portobello Rosemary Garlic Burger Stacks. My daughter loves portobello mushrooms & this is by far her favorite burger. They are so full of flavor. You won’t even miss the bun!
The 1st thing you do is mix 100% grass-fed ground beef with sea salt, garlic powder & chopped fresh rosemary. I have rosemary growing on my deck. I love the way it smells & absolutely love it with garlic!
Once you have it all mixed up, shape into 4 large hamburger patties. Since I only needed 3 burgers & had 2 lbs of ground beef I made 6 so we would have leftovers for tomorrow night. I’m always thinking ahead so that it’s easier the next day.
After you get the burgers shaped, set them aside.
Get out the portobello mushroom caps & line a pan with parchment paper if you have it. (clean up is so much easier) Remember to remove the stem & scrape out the inside. Drizzle with EVOO, & Coconut Aminos & sprinkle with garlic powder.
Now it’s time to put the burgers on the grill & mushrooms in the oven (or grill if you would like). If you don’t have a grill, a Black Iron Skillet works great or you could get an indoor grill like this one.
I also made Rosemary Garlic Sweet Potato Fries that I put in the oven about 10-15 min before the mushrooms. While burgers are cooking I cook the bacon, slice the avocado & onion.
Look at how yummy that looks! Now start stacking! If you are not AIP, slather on a good helping of Primal Kitchens Avocado Mayo or make your own Homemade Mayo! So easy!

Delicious! We’re having bacon burgers tonight and I sure wish I had some portabella’s now!
