Collin’s Grilled Portabello Mushrooms: A Meaty Delight

The first time I made these grilled portabellos, my normally veggie-averse son, a staunch believer in the “meat-only” food group, devoured two whole caps without hesitation. It was a small miracle, a culinary triumph achieved not through trickery, but through flavor. He actually asked for seconds! Watching him happily munch away, convinced he was eating some exotic kind of steak, was a victory I savored almost as much as the delicious mushrooms themselves. This recipe has become a staple, proving that even the pickiest eaters can be won over with a little culinary creativity.

Recipe Overview

Prep Time: 1 hour 15 minutes
Cook Time: 8 minutes
Total Time: 1 hour 23 minutes
Servings: 6
Yield: 6 mushroom caps
Dietary Type: Vegetarian

Ingredients

6 portabella mushroom caps
3 tablespoons extra virgin olive oil
6 cloves roasted garlic
1/4 cup crumbled blue cheese
3 tablespoons balsamic vinegar
1 teaspoon dried rosemary
1 teaspoon thyme
1 teaspoon oregano
Salt and pepper to taste
3 tablespoons margarine (or butter, if preferred)

Equipment Needed

Baking pan
Food processor
Grill

Instructions

Begin by thoroughly dusting the mushroom caps. This removes any dirt or debris clinging to the surface. A dry paper towel works perfectly for this.
Place the mushroom caps in a baking pan, with the bottom side facing up. This allows them to effectively soak in the marinade.
In a small bowl, mix together the extra virgin olive oil, balsamic vinegar, dried rosemary, thyme, and oregano. Season generously with salt and pepper.
Pour the herb and oil mixture evenly over the mushrooms. Ensure each cap is well-coated.
Marinate the mushrooms for approximately one hour. This allows the flavors to penetrate deeply into the mushroom caps. If you have more time, marinating for a longer period (up to 4 hours in the refrigerator) will result in even more flavorful mushrooms.
While the mushrooms are marinating, prepare the blue cheese mixture. Combine the roasted garlic, crumbled blue cheese, and margarine (or butter) in a food processor.
Process the ingredients until the mixture is smooth and creamy. This will create a flavorful topping that melts beautifully on the grill.
Preheat your grill to medium heat.
Carefully place the marinated mushroom caps on the grill, with the bottom side down.
Grill the mushrooms for about 3 minutes. This will give them a good sear and begin to cook them through.
Flip the mushroom caps over.
Divide the blue cheese mixture evenly between the mushroom caps, spreading it over the surface.
Grill for an additional 5 minutes, or until the blue cheese mixture is melted and bubbly. The mushrooms should be tender and slightly caramelized around the edges. You can test doneness by gently pressing on the mushrooms; they should yield easily.
Carefully remove the grilled portabello mushrooms from the grill and serve immediately.

Expert Tips & Tricks

Roasting Garlic: For the best flavor, roast your own garlic. Simply wrap a whole head of garlic in foil with a drizzle of olive oil and bake at 400°F (200°C) for about 45 minutes, or until the cloves are soft and fragrant.
Mushroom Prep: To prevent the mushrooms from becoming soggy, avoid washing them directly under running water. Instead, use a damp paper towel to gently wipe away any dirt.
Flavor Boost: For an extra layer of flavor, try adding a splash of Worcestershire sauce or soy sauce to the marinade.
Grill Marks: To achieve beautiful grill marks, avoid moving the mushrooms around too much while they’re grilling. Let them sear undisturbed for a few minutes before flipping.
Cheese Alternatives: If blue cheese isn’t your thing, feel free to substitute it with another flavorful cheese like goat cheese, feta, or even a sharp cheddar.

Serving & Storage Suggestions

Serve these grilled portabello mushrooms hot off the grill as a main course, a hearty vegetarian sandwich filling, or a flavorful side dish. They pair perfectly with a fresh salad, grilled vegetables, or roasted potatoes.

Leftover grilled portabello mushrooms can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, you can warm them in a microwave, oven, or skillet until heated through. Be mindful that reheating may alter the texture slightly. Reheating in a skillet with a bit of olive oil will help retain some of the original grilled texture.

These mushrooms are best enjoyed fresh and aren’t ideal for freezing, as the texture can become quite mushy upon thawing.

FAQs (Frequently Asked Questions)

Q: Can I use dried herbs instead of fresh?
A: Yes, dried herbs work perfectly well in this recipe. Just be sure to use about half the amount called for in the recipe, as dried herbs are more potent than fresh.

Q: How do I prevent the mushrooms from drying out on the grill?
A: Marinating the mushrooms for at least an hour is crucial for keeping them moist. Also, avoid overcooking them. They’re done when they’re tender but still have a slight bite.

Q: Can I make the blue cheese mixture ahead of time?
A: Absolutely! The blue cheese mixture can be made a day or two in advance and stored in the refrigerator. This will save you time on the day of grilling.

A: Gently wipe the mushrooms with a damp paper towel to remove any dirt or debris. Avoid soaking them in water, as they can become waterlogged.

Q: Can I broil these mushrooms instead of grilling?
