Are there certain vegetables your kids don’t like to eat? For a lot of parents, that veggie is mushrooms. I found that for every veggie that kids refuse to eat, there’s a way to fix it that most kids will absolutely love, and they will request that the food be fixed that way every time.

Stuffed Portobello mushrooms baked in the oven is my go-to method for making kid-friendly mushrooms.

Maybe you’ve never tried to make these, but this is an absolutely quick and easy way how to cook Portabello mushrooms that just about everyone will love. Even if you have picky eaters and people who refuse to eat mushrooms, when you cook it in the oven stuff it with cheesy goodness, it’s hard for anyone to refuse it.

Just the smell alone is enough to entice most people to give it a bite. After one bite, I think anyone would be hooked.

Maybe you don’t know how long to cook Portobello mushrooms or what to put in them how to prepare them for baking, and that’s okay. I’m going to show you how to cook Portobello mushroom caps stuffed mushrooms in a couple different ways, cooking them on the stove and in the oven.

How to Prep Portobello Mushrooms for Cooking

Before you cook your mushrooms, you need to prepare them. You might be inclined to wash your mushrooms before cooking them, but that’s not actually the best way to clean them. Ideally, you should wipe them with a damp cloth.

You want to clean off the debris and look for signs of degradation and parts that need to be removed. Washing the mushrooms directly in water can turn them mushy, which we don’t want.

So, wipe the Portobello mushrooms clean with a damp cloth and then pull out or cut off the stem. The stem has a different texture and density to it than the rest of the mushroom. So, it needs to be prepared a little differently than the other parts.

Some people serve the stems separately or put them in different dishes than the rest of the mushroom. I’m going to show you how to incorporate the stems into the stuffed mushroom as you cook this dish. I don’t like anything to go to waste if it doesn’t have to.

How to Properly Prepare Portobello Mushrooms

How to Cook Portobello Mushrooms in the Oven

We’re going to use a few different ingredients for this to make a flavourful and delicious stuffed mushroom. I like to chop up garlic, thyme, salt, and pepper in the stuffed mushrooms. Of course, stuffed mushrooms benefit from plenty of cheese as well.

So, when we prepare our mushrooms, you need some garlic chopped up and some cheese grated. You can use whatever kind of cheese you want, but I suggest mozzarella cheese for that classic look and flavour. 

Preheat your oven to 400 degrees Fahrenheit. While the oven is heating, you can prepare the fillings for your stuffed mushrooms. Mixed together your shredded cheese, garlic, salt, pepper, and thyme.

Grease a baking sheet and rest your prepared Portobello mushrooms on there. How to cook Portobello mushrooms in oven and use the stems? You will need to cut up the stems, dicing them into small pieces. You can cook them up in a little butter with the garlic.

You don’t have to cook the garlic ahead of time, but if you’re going to cook the stems and use them in the stuffed mushrooms, I would suggest cooking them with the garlic together. Then, mix all of your fillings together and spoon some into each mushroom cap.

You only want to fill the cap and not overflow it, otherwise the fillings will overflow onto the pan and may be wasted. How to cook Portobello mushrooms in a pan in the oven?

You can cook your mushrooms for 15 to 20 minutes in the oven. Some people prefer to add the cheese in later and keep that separate from the rest of the fillings. I think it is simpler to mix everything at once and fill the mushrooms completely before putting them into the oven, but it’s up to you.

If you want to add the cheese in later and ensure that it melts fully, then you can cook the mushrooms for 15 minutes in the oven and then add in the cheese. Cook for an additional 5 minutes for the cheese to melt and turn golden brown.

How do you know when your Portobello mushrooms are done cooking? They will be tender through and through.

How to Cook Portobello Mushrooms on Stove

If you can you Portobello mushrooms on the stove, you’re basically sautéing them. That’s the best way to cook them in a pan. Once again, take out the stems and you can dice those up and cook them with everything else or set them to the side.

The stems will need to cook thoroughly to become tender, but they will probably not get as tender as the rest of the mushroom. When cooking mushrooms on the stove, be sure to cook them in some butter to help them become tender and to keep them from sticking to the pan.

When I sauté mushrooms on the stove, I usually cut them into slices. This helps them to cook thoroughly, and they need that because they’re not enjoying the convection heat of an oven.

You can cook baby Portobello mushrooms this way as well. You probably don’t even need to slice those, because they’re so small and they will cook all the way through on the same heat as the slices of larger Portobello mushrooms.

How to cook baby Portobello mushrooms? Just cook the baby Portobello mushrooms or slices of larger mushrooms in a pan in some butter on medium heat about 5 minutes. Instead of butter, you could use vegetable oil or olive oil for cooking as well. You can garnish your finished mushrooms with some cheese, parsley, or salt and pepper.

How to Cook Portobello Mushrooms on the Grill

This is another method for cooking Portobello mushrooms where you can use the whole mushroom, even if it is a large mushroom. You can make these stuffed mushrooms as well, just like you did in the oven. The large Portobello mushrooms cook a lot like steak on the grill.

Just turn on your heat, cook the mushrooms on one side until they brown, and then flip them over until they brown on the other side.

How long to cook portobello mushrooms on grill? They only need to cook for about 3 or 4 minutes on the grill. You can marinate the mushrooms ahead of time, if you want them to be more savoury and more flavourful.

For a simple homemade marinade, I mixed together soy sauce, garlic powder, rosemary, and balsamic vinegar. Just marinade your mushrooms for about 10 minutes before grilling them.

These are a few of my favourite ways to make Portabello mushrooms, and I hope you find one that everyone will enjoy.
