First Step: Gather and Prep Your Ingredients Start by pulling together all the ingredients and setting aside 5 minutes for prep this keeps everything smooth and organized. Slice 1 lb of mushrooms like button or baby bellas in half or thirds, and mince 4 cloves of garlic for the main mix. For variations, measure out 2 tablespoons of balsamic vinegar and cut 2 pounds of button mushrooms in half if you’re marinating. If you’re adapting for vegan needs, swap butter for a plant-based option here, and have tools like foil or skewers ready to make grilling garlic butter grilled mushrooms even easier.

Second Step: Prepare the Mushroom Mixture In a large bowl, whisk together 1/4 cup melted butter, the minced garlic, 1/2 teaspoon salt, 1/2 teaspoon pepper, and 1 teaspoon garlic salt, then add the sliced mushrooms and 1-2 tablespoons chopped parsley, tossing to coat evenly this takes about 2 to 3 minutes. For the marinated variation, mix 2 tablespoons balsamic vinegar, 1 tablespoon soy sauce, and half of the additional 4 cloves minced garlic in another bowl, then add the 2 pounds of halved mushrooms and let them marinate for 30 minutes. If you’re aiming for low-calorie, use less butter in the mix to keep your garlic butter grilled mushrooms light while maintaining that flavorful punch.

Third Step: Set Up for Grilling Preheat your grill to 350 degrees for even cooking, which takes about 5 to 10 minutes, and lay out a large sheet of heavy-duty foil if using the primary method. For variations, oil the grill grates or prepare skewers for the marinated mushrooms to prevent sticking. Place the coated mushrooms in the center of the foil, fold the sides to seal tightly, or skewer the marinated ones for direct grilling this step sets the stage for perfectly tender garlic butter grilled mushrooms, and you can adapt by using an oven if grilling isn’t an option, baking at 350 degrees instead.

Fourth Step: Grill the Mushrooms Cook the foil packet on the grill for 15 minutes, then flip and grill for another 10 to 15 minutes until tender for the variation, grill skewered mushrooms for 5 minutes per side on medium heat, basting with the garlic butter mixture midway. This step takes 25 to 30 minutes total, and for dietary tweaks, ensure vegan swaps don’t alter the cook time, keeping garlic butter grilled mushrooms juicy and flavorful. Remember, if you’re making it low-calorie, monitor the butter to avoid excess, and test doneness by checking for a slight char and softness.

Fifth Step: Add Finishing Touches Once off the grill, let the mushrooms sit for a few minutes to cool slightly, then sprinkle with extra garlic salt if needed for that final flavor boost this helps the tastes settle in, taking just 2 to 3 minutes. For the marinated version, drizzle the sautéed garlic butter over the top right away. If you’re customizing, stir in fresh herbs or veggies here to enhance, and taste to adjust seasonings, making your garlic butter grilled mushrooms even more versatile for different palates.

Final Step: Finishing Touches and Serving Serve the garlic butter grilled mushrooms immediately in the foil for easy sharing or transfer to a bowl, garnishing with more parsley if desired this yields about 4 servings and is ready in under 5 minutes for plating. Pair it with grilled steak or burgers for a complete meal, and for low-calorie preferences, keep portions light. Whether you’re enjoying it as a side or main, this step ensures garlic butter grilled mushrooms shine, with options to adapt for solo diners or larger groups dig in and savor the smoky, garlicky goodness!
