Ingredients for Stuffed Portobello Mushrooms
- 4 portobello mushrooms
- 2 tablespoons olive oil
- 1 yellow onion, finely chopped
- 2 garlic cloves, minced
- ½ cup red bell pepper, finely diced
- 4 oz cream cheese, softened
- ½ cup sour cream
- 2 cups cooked and shredded chicken (or 14 oz diced artichokes for a vegetarian option)
- 5 oz chopped spinach, thawed and drained
- 1 cup shredded mozzarella cheese, divided
- ½ cup grated Parmesan cheese
- ½ teaspoon black pepper, or to taste
- ½ teaspoon salt, or to taste
Substitution Options
If you want to switch things up, here are some ideas:
- Chicken: Swap with turkey, ham, or even crumbled tofu for a plant-based twist.
- Cream cheese: Use ricotta or mascarpone for a lighter texture.
- Mozzarella: Try cheddar or Gouda for a sharper flavor.
- Spinach: Kale or Swiss chard works well too.
Step 1: Preheat and Prep
Start by preheating your oven to 220°C (425°F). Grab a baking sheet with edges and grease it lightly with olive oil. Now, take those beautiful portobellos and remove their stems. Scrape out the gills under the caps—trust me, this helps the filling sit better. Brush both sides of the mushrooms with olive oil and place them face down on the sheet. Pop them in the oven for 10 minutes to soften them up. Pro tip: Rinsing the mushrooms briefly under water won’t hurt, but pat them dry thoroughly to avoid sogginess.
Step 2: Sauté the Veggies
While the mushrooms roast, chop up the stems finely. Heat a teaspoon of olive oil in a nonstick skillet over medium heat. Toss in the onion, garlic, chopped stems, and red pepper. Cook until everything is soft and fragrant—about 5 minutes. The aroma will fill your kitchen and make everyone curious about what’s cooking. Pro tip: Keep stirring to prevent the garlic from burning; no one likes bitter garlic!
Step 3: Mix the Filling
In a mixing bowl, combine the softened cream cheese and sour cream. Beat them together until smooth and fluffy. Add the sautéed veggies, cooked chicken (or artichokes), spinach, half the mozzarella, and all the Parmesan. Season with salt and pepper to taste. Stir everything until well combined. The mixture should be creamy, vibrant, and bursting with color. Chef’s tip: Taste as you go! Adjust the seasoning to match your preferences.
Step 4: Assemble and Bake
Flip the roasted mushrooms over and spoon the filling generously into each cap. Top with the remaining mozzarella for that irresistible cheesy pull. Slide the tray back into the oven and bake for 12–16 minutes, or until the cheese is bubbly and golden. Your kitchen will smell heavenly, and your patience will pay off when you see those perfectly stuffed beauties emerge.

Chef’s Secret
For an extra layer of flavor, sprinkle a pinch of smoked paprika into the filling. It adds a subtle smokiness that pairs beautifully with the earthy mushrooms.
Extra Info
Did you know portobello mushrooms are low in calories but high in nutrients? They’re packed with antioxidants, potassium, and B vitamins. Plus, their meaty texture makes them a fantastic substitute for beef in burgers and sandwiches. Fun fact: They’re also known as “the steak of the vegetable world”!
Necessary Equipment
You’ll need:
- Baking sheet with edges
- Nonstick skillet
- Mixing bowls
- Spatula
- Measuring cups and spoons
Storage Tips
If you have leftovers, store them in an airtight container in the fridge for up to 3 days. Reheat in the oven to keep the mushrooms firm and the cheese melty.
Freezing isn’t recommended because mushrooms can become watery when thawed. However, you can freeze the filling separately for up to a month.
To reheat, cover the mushrooms loosely with foil to prevent drying out. Warm them at 180°C (350°F) for 10–15 minutes.
Tips and Advice
Press the spinach thoroughly to remove excess moisture. Too much liquid can make the filling soggy. Also, don’t skip roasting the mushrooms before stuffing—they absorb less liquid this way.
Presentation Ideas
- Garnish with fresh basil or parsley for a pop of green.
- Serve on a wooden board for a rustic look.
- Pair with a side of crusty bread or a simple green salad.
Healthier Alternatives
Here are six ways to lighten up this recipe:
- Use Greek yogurt: Swap sour cream with plain Greek yogurt for fewer calories.
- Go lean: Replace chicken with turkey breast or plant-based proteins.
- Low-fat cheeses: Opt for reduced-fat mozzarella and Parmesan.
- Add more veggies: Include zucchini or carrots for extra nutrition.
- Gluten-free breadcrumbs: Sprinkle on top for crunch without gluten.
- Olive oil spray: Use a spray bottle to lightly coat instead of drizzling.
Mistake 1: Skipping the Mushroom Prep
Some folks skip removing the gills and roasting the mushrooms beforehand. This leads to watery results since raw mushrooms release a lot of moisture. Always prep them properly for the best texture.
Mistake 2: Overfilling the Caps
Filling the caps too full might seem generous, but it causes the filling to spill over during baking. Aim for a slightly rounded mound to keep everything intact.
Mistake 3: Using Wet Spinach
Wet spinach dilutes the filling. Press it firmly between paper towels or a clean cloth to remove every last drop of water.
Mistake 4: Underseasoning
The filling relies on proper seasoning to shine. Taste as you mix and adjust accordingly to ensure bold, balanced flavors.
Mistake 5: Overbaking
Overbaking dries out the mushrooms. Stick to the recommended time and check for golden, bubbly cheese as your cue to remove them.
