Let’s Make it together
Prepare the Marinade: In a bowl, whisk together olive oil, balsamic vinegar, minced garlic, dried oregano, salt, and pepper. This fragrant blend sets the stage for your mushrooms’ flavorful transformation.
Clean the Mushrooms: Gently wipe each Portobello mushroom cap with a damp paper towel to remove any dirt. Avoid rinsing under water as they can absorb moisture.
Marinate: Place the cleaned mushrooms in a shallow dish and pour the marinade over them. Let them soak up those delicious flavors for at least 30 minutes.
Preheat Your Grill: Get your grill ready by preheating it to medium-high heat (about 400°F or 200°C). A hot grill ensures those beautiful char marks we all love!
Grill the Mushrooms: Place marinated Portobello caps on the grill and cook for approximately 5-7 minutes per side. Watch as they sizzle and caramelize beautifully.
Serve and Enjoy!: Once tender and juicy, remove them from the grill. Serve your grilled Portobello mushrooms warm, drizzled with any remaining marinade for extra goodness.
