How to select portobello mushrooms for grilling
When buying portobello mushrooms, look for caps that have opened up nicely (refer to the photo below). These mushrooms will cook through faster and more evenly. If you bought caps that look thick and closed, you can remove a little bit of flesh around the rim. I suggest piercing the mushrooms with a fork, which helps the marinade to get inside the holes and also helps speed up the cooking process a bit.
Main Ingredients
- Portobello Mushrooms.
- Balsamic Vinegar. Adds sweet acidity to the mushrooms, especially as they grill.
- Olive Oil. Or any oil you like to use, such as canola, avocado, or grapeseed.
- Oregano. Adds a nice earthy taste.
- Garlic Powder. For a delicious pungent flavor.
- Paprika. Sweet, smoked, or hot, which ever you like best.
- Salt. To taste.
- Sriracha. This adds a touch of heat to this dish.
How to Make Grilled Portobello Mushrooms
1. Gently wash the portobellos and pat them dry with paper towels. Remove the stems and carefully pierce the mushrooms all around with a fork.
2. Prepare the marinade by mixing the balsamic vinegar, olive oil, oregano, garlic powder, paprika, salt, and sriracha in a small bowl.
3. Spoon the marinade over the mushrooms until they are covered and then let them rest for 10-15 minutes so it can be absorbed.
4. Place the mushrooms, gill side up, on the grill pan. Grill for about 5 minutes.
5. Flip the mushrooms and grill for about 4-5 minutes, brushing them with marinade drippings, if desired.

You have a fabulous collection!!!! Think about a cookbook! I truly would buy it.
I love how you put combos of vegetables together-they work when one can't think of what to do.

Hi Grace! Thank you so much for the kind words. I have two small kids and two web sites at this point, but maybe in a few years I will have enough time for the cookbook. I will keep cooking and practicing until then. 🙂
