A portobello mushroom has about 20 calories, but that changes with the marinadeโ€”assuming 50% absorption of the marinade (which is high), they are still under 100 calories and fit that will fit a healthy diet like a low-calorie or low-fat diet or even a low-carb keto diet.

This grilled portobello mushroom recipe is from my local cooking school. I have expanded the discussion and provided detailed instructions with photos. Please enjoy this excellent alternative to have in your grilling bag of tricks.

๐Ÿ„About Portobello Mushrooms

A portobello mushroom is a mature form of the common button mushroom but is allowed to grow and mature. They are cultivated in many countries and are among the most common mushrooms.

The spelling has common variations, including portobello, portabella, and portobella. They are all the same, and all the spellings are acceptable.

Recipe Notes

Pro Tips

  1. You need large relatively fresh portobello mushrooms for this recipe.
  2. I calculated the nutrition with one-half of the marinade staying in the final dish but it will vary by the dryness of the mushrooms. Commonly only one-tenth of a marinade is used to calculate this.
  3. The cooking timing matches grilled burgers perfectly and I use this for casual grill parties so the guests will have a choice.
  4. Cook to final color and not by time.
  5. Vary the marinade to your taste.
