Best mushrooms for grilling

There is a variety of mushrooms that you can grill, but the best mushrooms to grill are portobellos and shiitakes. The reason is that they have big caps and are easy to flip. There is no need to add skewers. Unlike bigger mushrooms, smaller mushrooms like creminis are tiny. It is almost impossible to grill them without adding skewers as they can just fall through the grate. You can grill them whilst they are full, but you can hardly flip them. However, they grill so well on high and direct heat, unlike bigger mushrooms that require less heat as they easily burn before they are done.

How to prepare portobello mushrooms


As much as you should avoid water inside the mushrooms to avoid making them saggy, you still need to clean them till they do not have any dirt. I advise you to use a moist towel as you clean the mushroom.

Mix the filling

You do not have to rush mixing the filling only because the grill is on. You have to take your time, although it does not have to take longer. The ingredients that make up the filling include bacon, jalapeno, cheese and onion. You can even add goat cheese, dried tomatoes, Italian herb seasoning and black pepper that is if you are making stuffed Portobello mushrooms.


Since the mushrooms are clean and the filling is ready, you may now fill up your mushrooms. You can fill up any amount of your filling as long as it will not spill out during grilling. You need to make sure that there is enough room for cheese topping left as you will have to add the cheese later on during the grilling process.

Should you marinate the mushrooms?

Marinating mushrooms is, of course, a choice but it is also a great idea. You need to marinate the mushrooms for even up to 24 hours. The marinade has to contain oil for perfect results. Since the filling includes spices and herbs, you might be wondering if it is advantageous to marinate mushrooms. It adds more flavor to the mushroom making it tasty. Your taste-buds can confirm. Marinating mushrooms is the first step when it comes to grilling. You can, however, still, continue adding the marinade throughout the whole grilling process.

How long to grill mushrooms

It takes 10 to 12 minutes to grill mushrooms. Mushrooms are very quick to grill, unlike meat. You have to continually check if you feel that it might get done before 12 minutes. The first 10 minutes are for grilling only then the last 2 minutes to add grated or shredded cheese and grill again. Adding cheese makes the mushroom yummy, tasty and rich.

Pro tips

Leave your cream cheese out for at least 30 minutes before use. This will allow it to soften, making it more pliable and easy to mix when the time comes to use it. You can do this while you wash and prepare the mushrooms, and while you cook the bacon.

Make sure you use a paper towel to pat down the bacon after you have cooked it. Excess fat and grease can ruin the consistency and flavor of the cream cheese in stuffed mushrooms.

When you are buying the mushrooms, make sure there will be enough space inside the caps for easy filling. Just in case there is little space inside the caps, you can use a spoon to scoop out some more mushroom to make more space.

Ensure the mushrooms are dry before you grill them. Moisture can ruin the quality of the mushrooms when grilled.
