Portobello Mushrooms
Ingredients:
- 4 portobello mushrooms, large
- 3 tbsp olive oil
- Garlic powder, salt, black pepper, and paprika, to taste
- 2 cups mozzarella cheese, shredded
- 1 cup cherry tomatoes, halved
- Fresh basil or parsley, chopped, for garnish
Method:
Start Cooking- Preheat the oven to 425°F (220°C).
- Clean the mushrooms, remove the stems, and scrape out the dark gills if desired.
- Brush the mushrooms inside, outside, and around the edges with the olive oil.
- Season with garlic powder, salt, black pepper, and paprika.
- Fill each mushroom with mozzarella and top with the halved cherry tomatoes.
- Arrange the mushrooms on a lightly oiled baking sheet.
- Bake for 25 minutes, or until the mushrooms are tender, the cheese is melted, and the tomatoes are softened and lightly roasted.
- Broil for 1–2 minutes if you’d like a more golden top.
- Garnish with fresh basil or parsley and serve warm. Bon appétit!
Notes:
- Wipe portobello mushrooms with a damp paper towel or a soft mushroom brush to remove any dirt. While you can rinse them briefly if needed, avoid soaking them, as mushrooms absorb water easily. Excess moisture can make them release more liquid during roasting.
- Removing the dark gills is optional. They are edible but can trap small bits of dirt and darken the filling. Removing them also creates more room for toppings and helps reduce excess moisture while roasting.
- Fresh mozzarella can release more liquid than low-moisture shredded mozzarella. For the best texture, use shredded low-moisture mozzarella.
- Let the mushrooms rest for 2–3 minutes after baking so the cheese can settle before serving.
- For fresh garlic flavor, sauté 2 minced garlic cloves in a little olive oil until fragrant, then brush the garlic oil over the mushrooms before baking.
- Add a handful of baby spinach under the mozzarella for extra color and nutrition.
- Top each mushroom with a small cube of butter before baking for a richer finish.
- Sprinkle grated Parmesan over the mozzarella for a sharper, cheesier flavor.
- Add sliced black olives or roasted red peppers.
- Finish with a drizzle of balsamic glaze or a pinch of crushed red pepper flakes.
- Serve these mushrooms as a side with grilled chicken, steak, salmon, or pasta.
- They also make a satisfying vegetarian main course with a simple green salad or crusty bread.

FROM THE PANTRY
Portobello mushrooms
WHY WE LOVE IT
Their large size and dense, meaty texture make them one of the best natural meat substitutes.
Their rich umami flavor pairs beautifully with cheese, herbs, vegetables, and grilled meats.
Their wide, bowl-shaped caps are perfect for stuffing with a variety of fillings.
They roast, grill, bake, and sauté beautifully, making them one of the most versatile mushrooms in the kitchen.
A LITTLE STORY
Portobello mushrooms are the fully mature stage of the common cultivated mushroom, Agaricus bisporus.
White button mushrooms, cremini (baby bella) mushrooms, and portobello mushrooms are all the same species, harvested at different stages of maturity.
In the 1980s, mature brown mushrooms were much less popular than white button mushrooms and often had little commercial value.
Mushroom growers popularized the Italian-sounding name “portobello” in the 1980s, transforming mature mushrooms into a premium culinary ingredient.
DID YOU KNOW?
Cremini (baby bella) mushrooms eventually grow into portobello mushrooms if left to mature.
The large caps make portobellos popular as burger substitutes, pizza bases, and edible bowls for fillings.
As they mature portobellos naturally lose moisture, giving them a firmer, steak-like texture than younger button or cremini mushrooms.
The dark gills are completely edible, though many cooks remove them to create more room for fillings and reduce excess moisture.
