Looking for an easy, delicious, and healthy recipe to make for dinner tonight? Stuffed Portobello Mushrooms are the perfect meal! This recipe is easy to follow, and it's sure to please everyone at the table. Plus, the portobello stuffing can be used for many dishes as a great way to get your daily dose of vegetables.
We love having a Stuffed portobello mushroom as an appetizer or side dish or having two as a main course next to a green salad. These beauties are ready in 30 minutes, and the recipe is perfect for any occasion or a meatless dinner.
They are not only present in our day-to-day lives but are also one of our fall season favorites, and they always show up on our Christmas table.
These stuffed mushrooms require a handful of simple ingredients, sautéd together to make the stuffing, and then used to top the mushroom caps.
- Portobello mushrooms
- Sun-dried tomatoes
- Small onion
- Garlic cloves
- Fresh celery
- Fresh parsley
- Tarragon leaves (fresh or dried)
- Fresh basil
- Vegan Parmesan cheese (our 5-mins vegan parm recipe)
Baked portobello mushrooms are made by simply baking the caps for a couple of minutes while you make the stuffing, and as soon as the mushrooms are ready, you pile the portobello stuffing on top and then briefly bake them again for the stuffing to settle.
Preheat oven to 350 ºF (175 ºC). Then on a lined baking sheet, place the cleaned mushroom caps, and stalk side up. Remove the stalk.
Season, sprinkling some salt and black pepper, and optionally a drizzle of olive oil. You need to remove the portobello mushrooms from the oven after 15 minutes when they are half-cooked.
Chop the portobello stuffing ingredients
It is important to finely chop the ingredients to have a stuffing that holds together.
Prepare the portobello stuffing
In a saucepan on medium heat, sauté the chopped onion, celery, and garlic, and then add the chopped dried tomato, followed by the chopped herbs and vegan parmesan cheese. You can optionally add the chopped mushroom stems.
Fill the caps
With a spoon, abundantly pile up the filling on each mushroom cap. The baked portobello mushrooms' stuffing will set a bit after baking. Top with vegan parm or shredded vegan mozzarella cheese.
Return the portobello mushrooms to the oven and bake for about 10 minutes or until the mushrooms are fork-tender.
Transfer the baked portobello mushrooms to serving plates and garnish with chopped basil. Serve right away with a green salad with cherry tomatoes.
This Recipe for Portobello Stuffed Mushrooms is gluten-free and can also be made WFPB (Whole foods plant-based compliant), simply by removing the olive oil.
In fact, when I am cooking oil-free, I sauté the onions, garlic, and celery just with two or three tablespoons of water to prevent the veggies from sticking to the bottom of the saucepan.
Vegetarian stuffed portobello mushroom recipes usually call for goat cheese, mozzarella cheese, and grated parmesan cheese. We ditch the dairy here to make these vegan stuffed mushrooms.
Goat cheese has a lot of umami, so we are using dried tomato, which adds lots of flavors, and is perfect for red risotto and sun-dried pesto pasta.
We also use our vegan parmesan cheese recipe, to replace vegan parmesan. It has a nutritional yeast base that works very nicely on this recipe.
The bigger the portobello mushrooms, the most satisfying the main dish, but if you are using these stuffed portobello mushrooms as your vegan side dish, you can use medium portobellos.
Smaller mushrooms will leave you with extra stuffing that you can use for dry pasta, sandwiches, or even ravioli stuffing.
You can also use cremini mushroom caps, which are nothing more than smaller portobello mushrooms. You will just need way less filling and baking time.
I find that tarragon is the herb that takes on this recipe, and gives it the most personality, as basil and parsley always call for our well-known Italian recipes flavors, Tarragon, on the other hand, calls for French.
For this portobello stuffing, we use both, so we are still within the Mediterranean flavor spectrum but concentrating more on the French side.
You could also replace basil or parsley with herbs such as rosemary, sage, or marjoram. Feel free to use dried basil; if you cannot find it fresh, use 2 tablespoons instead of a bunch.
We like using yellow onion, but you could also use white or red onion if you want to add some caramelized sweetness.
Spring onions, green onions, and even leeks work well for this portobello mushroom recipe too.
Out of fresh garlic? No worries, use a teaspoon of garlic powder.
You can add protein to this side dish by adding 4 ounces of crumbled extra-firm tofu to the mix; after sautéing the veggies, sauté the tofu together, adding 3 minutes to your prep time, always on medium heat.
You can also add one bunch of chopped spinach, which will wilt immediately while sautéing.
Make sure you adjust the seasoning, salt, and pepper. More volume calls for seasoning adjustments.
👪 Serving size
I find this portobello stuffing delicious, and sometimes I even use it to make an easy dinner, combined with boiled dry pasta or warm salads or cornbread stuffing on your holiday table.
Sometimes I switch our Stuffed Red Pepper recipe's filling for this one for a change; in that case, I like adding a cup of cooked rice to make up for the mushroom flesh that pairs very well with the stuffing.
In this side dish recipe, the portobello mushroom has less flavor and pairs with the dried tomato stuffing. In the case of red pepper, they have a lot of flavors and don't have enough flesh, to balance this rich stuffing. That's why the addition of rice balances things out on stuffed peppers.
🥢 How to serve
Enjoy your stuffed mushrooms with a green salad topped with a homemade vinaigrette, or simply with mashed potatoes or cornbread stuffing.
They also make great side dishes for pasta dishes.
Store leftover baked stuffed portobello mushrooms in an airtight container in the fridge for up to two days.
I find that after the second day, the mushrooms start smelling bad.
This recipe is not freezer friendly as fresh mushrooms don't thaw well.
🍄 How to clean portobello mushrooms
Mushrooms tend to absorb water, thus making them mushy; that's why there are two schools for cleaning mushrooms.
In one corner, you have people that say you should not have your mushrooms cleaned with water, and then the ones that say it is alright as long as you follow a couple of rules.
Both are valid; let's explore the Dry and Wet methods.
Wild portobello mushrooms can capture a lot of dirt, basically, everything the forest has to offer, including bugs; so it is essential to clean them; however, they should not be soaked.
When I attended the Gastronomy School in Mexico, I asked the Head Chef his opinion about this topic, water or no water?; he was very straight: mushrooms should be washed; Otherwise, that earth will end up on your plate, which can carry infections or forms of food poisoning.
However, you can still use water in different ways to ensure the mushrooms don't absorb any moisture, thus affecting your recipes.
When to use: when you will cook the portobello mushrooms anyway, as is the case with this roasted portobello mushrooms recipe, and that's because the heat will kill any unwanted bacteria.
To clean portobello mushrooms, use a dry cloth or paper towel. You may also clean the mushroom with water and a brush but never soak it.
If you are really set on cleaning the whole thing, removing the gills is possible; gently scrape the inner side with a teaspoon after removing the stem. Make sure not to damage them when you are doing this.
Optional: when cleaning medium or large portobello mushrooms, you will notice that the ends of the caps have some loose skin. You can start ripping them off and pulling them out. You will end up with a white portabella, as the brownish color lies on the skin.
There are special mushrooms brushes (affiliate link) (affiliate link) available in stores or online; I like this one since, in a single tool, you have both the mushroom brush and the gills remover. You can also use a soft-bristle toothbrush.
If you've already got a pinprick or two on the cap - don't worry; it's not too big of an issue as long as you don't soak the mushroom.
When to use: in recipes such as salads, when you have very dirty mushrooms, or when you plan to eat raw portobello mushrooms.
Soak the portobello mushrooms in a large bowl filled with water very briefly. Wash the mushroom caps delicately with the palm of your hands, removing any pieces of dirt.
Here in Italy, it is very common to get wild mushroom stems that are extremely dirty, but I also find them to be the most delicious. They are not farmed, so they are high in nutrients. This is the case with portobello mushrooms, cremini mushrooms, and also pioppini mushrooms.
That's why I use this method often, as soaking the portobello mushrooms in water will help dissolve dirt.
The Keyword here is Briefly; the intention here is not to leave the mushrooms soaking but to wash them actively and remove them from the water. Then pad-dry with a kitchen cloth or paper towels removing any excess water.
