Stuffed Portobello Mushroom Inspired By Mexico

January 24, 2017


I have always been a lover of mushrooms … mushrooms of all kinds but I have to say my favorite mushroom is the Portobello mushroom. Portobello mushrooms can be used in so many different ways … sauted, grilled or baked … geez you name it and they can do it. I especially love grilling a Portobello mushroom and eating it like you would a hamburger. In fact, I rarely eat regular hamburgers anymore I always opt for a juicy Portobello mushroom burger these days. They have such a wonderful texture and could easily be mistaken for ground beef.

Another way I love to eat a Portobello mushroom is stuffing it with my favorite cheese and veggies. Then bake it in the oven until the cheese melts and the mushroom is juicy. If you have a meat lover in the family, like I do, who insists on meat being part of the dinner time routine I will use ground beef or turkey as well. Which brings me to this recipe …

These delicious low-carb stuffed Portobello mushrooms are really easy to make and deliver a ton of great flavor. They are great for a super easy weeknight meal and Taco Tuesday will never be the same! To prepare the mushroom caps, gently remove stems by hand. Then, scoop out the gills with a spoon and discard. This will give you more room to add your toppings, plus it will remove the residual grit that can sometimes accumulate there.

For the taco seasoning, you can use either your favorite prepared blend or make up a batch of this super easy homemade version that can be stored in an airtight container for up to six months.
