Preparing Honey Balsamic Portobello Mushrooms:

When getting ready to grill your portobello mushrooms, all you will need to do is whisk together a simple marinade.  The ingredients are very popular to most marinades, so you may already have many of them on hand!  The marinade creates an amazing texture as it tenderizes, and intensifies the flavor of your mushroom too!

  • Olive oil: Penetrates the skin and brings the flavors of the marinade throughout the mushroom.
  • Butter: Melted to mix easily in marinade.
  • Garlic cloves: Minced garlic adds rich flavor!
  • Balsamic vinegar: Acts as a tenderizer because of its acidity.
  • Soy sauce: Adds saltiness to the marinade
  • Honey: Adds sweetness!
  • Salt and Pepper: To taste
  • Portobello Mushrooms: Be sure to clean them with a damp paper towel and remove the stem and gills before grilling.

How to Grill Portobello Mushrooms:

To grill portobello mushrooms, you will need to remove the stem, scrape out the gills and marinate them for 10 minutes in the refrigerator.  Then just place on the hot grill and flip halfway through cooking.  It is pretty simple and easy to do!  The grill will bring out the earthy flavors of the mushroom

  1. Whisk Marinade: In a small bowl whisk together olive oil, butter, garlic, soy sauce, sugar, and salt and pepper.
  2. Prepare portobello mushrooms: Gently remove the stem from the mushrooms.  Using a spoon scrape out the gills. Set the mushrooms in a 9×13 inch pan.  Add the marinade and soak for 10 minutes.
  3. Grill Mushrooms: Preheat the grill to medium high heat. Place the mushrooms on the grill and grill 5 minutes on each side for a total of 10 minutes.

The Recipe Critic Pro Tip:

For criss-cross grill marks on the outside, simply spin the portobello mushroom on the grill slightly around the 2 to 3 minute mark. This gives you a fun grill mark on the outside of the mushroom.

FAQ About Grilling Mushrooms:

Portobello mushrooms are in the vegetable food group despite the fact that they are not plants.  They are actually a fungi. So, that leaves lots of questions about how to care for them and prepare them well.  Here are some answers to the questions that you may have about properly preparing this delicious..ummm…vegetable?

  • Can you marinate too long? Since mushrooms are by nature very porous, it is possible to marinate them too long. They will soak up too much and may become too mushy if they sit too long in the marinate.  So, stick with 30 minutes of marinade before grilling.
  • How do you clean portobello mushrooms? Since the mushrooms grow in the ground it is necessary to clean them as the first step of preparing them. To clean the mushrooms, you need a damp paper towel.  Wipe the cap and stem of the mushroom to remove any dirt.
  • How do I choose a good portobello mushroom? A fresh mushroom should be firm and have a pleasant smell. Inspect them carefully before purchasing.  If they are slimy, have dark spots, or the gills are wrinkled, stay away!

How to Properly Store Portobello Mushrooms:

To store your fresh mushrooms until you are ready to grill them, start by removing any packaging from the mushrooms.  Then, place them either in a paper bag or on a tray and cover with a paper towel.  If storing in a ziploc bag, leave the bag open.  The key is you want to avoid the mushrooms getting too much moisture in a sealed container. Do not freeze fresh mushrooms, and use within a week of purchasing.

Once marinated and grilled, the mushrooms will need to be stored in an airtight container.  They will last in a refrigerator for 3-5 days or in the freezer for 10-12 months.
