Grilled Mushrooms in Vinaigrette

Ingredients You’ll Need:

2 (16oz) packages cremini or white button mushrooms, stemmed and dirt wiped off
Olive oil (for grilling, ideally in an oil mister or cooking spray)
2 T extra virgin olive oil (for the vinaigrette)
2 T freshly squeezed lemon juice
2 T minced fresh chives
2 T diced onion (finely diced for best texture)
1 t Dijon mustard
1/2 t honey
Pinch kosher salt and freshly ground pepper, to taste

Step-by-Step Instructions for Culinary Perfection:

1. Preparing Your Mushrooms for Grilling

The foundation of this dish is, of course, the mushrooms. Begin by selecting fresh, firm cremini (also known as baby portobello) or white button mushrooms. These varieties hold up exceptionally well on the grill, offering a satisfying meaty texture. Carefully wipe any dirt off the mushrooms with a damp paper towel. Avoid washing them under running water, as mushrooms are like sponges and will absorb too much liquid, leading to a less desirable texture when grilled. Once clean, gently remove the stems. While edible, removing the stems helps the mushrooms cook more evenly and makes them easier to skewer.

For grilling, skewering the mushrooms is highly recommended. Not only does it make them easier to handle on the hot grill, but it also ensures they cook consistently. If using wooden skewers, remember to soak them in water for at least 30 minutes prior to grilling. This prevents them from burning on the high heat. Thread the mushrooms onto the skewers, being careful not to pack them too tightly. Leave a little space between each mushroom to allow for even heat distribution and beautiful charring. Once skewered, lightly spray or brush the mushrooms with olive oil. This step is crucial for achieving that irresistible smoky char and preventing them from sticking to the grill grates.

2. Crafting the Zesty Vinaigrette

While your grill is heating up, turn your attention to the star of the show: the vinaigrette. This bright and tangy dressing will elevate the grilled mushrooms, infusing them with incredible flavor. In a medium-sized bowl, combine the extra virgin olive oil, freshly squeezed lemon juice, minced fresh chives, finely diced onion, Dijon mustard, and honey. The quality of your ingredients truly shines here, so opt for fresh lemon juice over bottled for the best flavor. Dijon mustard not only adds a wonderful piquant note but also acts as an emulsifier, helping to bind the oil and lemon juice together for a smooth dressing.

Whisk all the vinaigrette ingredients together vigorously until well combined and slightly emulsified. The dressing should be vibrant and fragrant. Finally, season the vinaigrette with a pinch of kosher salt and freshly ground black pepper to taste. Adjust the seasoning as needed, ensuring a perfect balance of acidity, sweetness, and savory notes. Set the vinaigrette aside, allowing the flavors to meld while your mushrooms are on the grill.

3. Grilling the Mushrooms to Perfection

Now, it’s time to fire up the grill! Preheat your grill to high heat. Achieving a high temperature is key to getting a beautiful char on the mushrooms quickly, locking in their natural juices and creating that desirable smoky flavor. Once the grill is hot, carefully place the mushroom skewers directly over the heat. Grill for approximately 4-5 minutes, turning them a couple of times to ensure even cooking and charring on all sides.

Keep a close eye on them; you’re looking for signs of deep browning and some distinct char marks, indicating they are cooked through and have absorbed that wonderful smoky essence. The mushrooms should soften, become juicy, and shrink slightly in size. Avoid overcooking, which can make them rubbery. The goal is tender, juicy mushrooms with a perfect char.

4. Tossing and Serving Your Flavorful Dish

Once the mushrooms are beautifully grilled, carefully remove them from the skewers and transfer them into the bowl with the prepared vinaigrette. It’s best to do this while the mushrooms are still warm; their heat will help them absorb the dressing even more effectively, allowing the flavors to penetrate deep into each mushroom. Gently toss the grilled mushrooms with the vinaigrette until they are thoroughly coated.

The beauty of this dish is its versatility in serving. It can be served warm, straight off the grill and mixed with the dressing, or at room temperature, making it an excellent option for picnics, potlucks, or meal prep. The flavors develop even further as it sits, so don’t hesitate to make it a little in advance. Garnish with a sprinkle of extra fresh chives for an added pop of color and freshness if desired.
