Ever pull a sad, rubbery mushroom off the grill and wonder what went wrong? You wanted a juicy, meaty burger substitute, but you got a wet sponge. I’ve been there, and I can tell you it doesn’t have to be that way.
Forget everything you think you know about grilling mushrooms. We’re going to make portobellos so good, you might forget all about the beef. This method is simple, fast, and gives you a perfect result every single time.
Grilled Portobello Mushrooms
What You’ll Need
- 4 large portobello mushrooms
- 1/4 cup olive oil
- 3 tablespoons balsamic vinegar
- 2 cloves garlic, minced
- 1 teaspoon dried oregano
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
Pro Tips
I’ve learned a few things over the years that make a huge difference. Don’t skip these.
- Don’t Wash, Just Wipe: Mushrooms soak up water like crazy. Never run them under the faucet. Just use a damp paper towel to wipe them clean. This stops them from getting soggy on the grill.
- Score the Caps: Use a small knife to gently cut a crisscross pattern on top of the mushroom caps. This helps the marinade get deep inside, making every bite flavorful.
- Gill Side Down First: Start grilling with the gill side facing the heat. This helps cook the mushroom through and prevents the cap from burning before the inside is done.
Tools for the Job
You don’t need a lot of fancy gear for this.
- Grill (gas or charcoal)
- Mixing bowl
- Whisk
- Tongs
- Basting brush
Substitutions and Variations
Feel free to play around with the recipe. It’s hard to mess this up.
- Vinegar: No balsamic? Red wine vinegar or even a splash of soy sauce works.
- Herbs: Try adding fresh thyme or rosemary instead of dried oregano for a different flavor.
- Spice it Up: A pinch of red pepper flakes in the marinade adds a nice little kick.
| Ingredient | Substitution | Note |
|---|---|---|
| Balsamic Vinegar | Soy Sauce or Tamari | Gives a more savory, umami flavor. |
| Dried Oregano | Fresh Thyme | Add fresh herbs at the end of cooking. |
| Olive Oil | Avocado Oil | Good for high-heat grilling. |
Make-Ahead Tips
You can prepare the marinade up to 3 days ahead of time. Just keep it in a sealed container in the fridge.
Let the mushrooms sit in the marinade for at least 30 minutes, but no more than a few hours. Any longer and they can get a little too soft.
How to Make Grilled Portobello Mushrooms
Step 1: Gently wipe your mushrooms clean with a damp paper towel. Pop the stems off.
Step 2: In a small bowl, whisk together the olive oil, balsamic vinegar, minced garlic, oregano, salt, and pepper.
Step 3: Place the mushrooms in a shallow dish and pour the marinade over them. Let them sit for about 30 minutes, flipping them once.
Step 4: Preheat your grill to medium-high heat.
Step 5: Place the mushrooms on the grill, gill side down. Cook for 4-6 minutes, until you see grill marks.
Step 6: Flip the mushrooms and cook for another 4-6 minutes. They’re done when they are tender and have nice char marks.
Step 7: Let them rest for a minute before slicing or serving whole.
Serving and Diet Swaps
These mushrooms are great on their own, but they also make an amazing burger on a bun with some lettuce and tomato. You can also slice them up and add them to salads or pasta.
| Diet Type | Ingredient Swap | Serving Suggestion |
|---|---|---|
| Gluten-Free | Use tamari instead of soy sauce (if using). | Serve on a gluten-free bun or over a salad. |
| Low-Carb | Serve as the main protein. | Pair with a side of grilled asparagus or zucchini. |
| Vegan | This recipe is already vegan. | Perfect as a vegan burger patty. |
Leftovers and Storage
If you have any leftovers, they’ll keep in an airtight container in the fridge for up to 3 days.
You can eat them cold, chopped up in a salad. Or, reheat them in a pan over medium heat for a few minutes until warmed through.
Frequently Asked Questions
Q1. Why did my mushrooms turn out soggy?
Ans: You probably washed them with water instead of wiping them. They also get soggy if they sit in the marinade for too long. Stick to 30 minutes for the best texture.
Q2. Can I make these without a grill?
Ans: Yes. You can use a grill pan on your stove over medium-high heat. You can also bake them in the oven at 400°F (200°C) for about 15-20 minutes, flipping halfway through.
Q3. Should I scrape out the gills?
Ans: You don’t have to. The gills are perfectly edible and have a lot of flavor. Some people remove them for looks, but it’s not needed.
