Hungry for something elegant, loaded with flavor, and honestly way easier than it looks? You’ve got to try these Caprese-stuffed portobello mushrooms. They never let me down. I’ve made them for busy weeknights and even for dinner parties, and every single time, people clear their plates.
So, how did this recipe come about? I wanted something that felt hearty and healthy but didn’t take forever to make. I’m obsessed with classic Caprese salad—think melty mozzarella, ripe tomatoes, fresh basil, and that sweet balsamic drizzle—but sometimes I just want more substance. Portobello mushroom caps totally fit the bill. They’re big, have that almost meaty bite, and their earthy flavor just ties everything together.
The best part? These mushrooms are all about keeping things simple. No tricky steps here. Prep takes just a few minutes, then the oven handles the rest. Roasting brings out the deep flavor and makes the mushrooms super tender. And the filling? You can play around as much as you want—swap in different cheeses, toss in some fresh herbs, or throw in a little garlic if you’re in the mood for a punch of flavor.

Ingredients Breakdown
- Portobello Mushrooms: 4 large portobello mushrooms (about 6-8 ounces/170-227 grams each). Choose mushrooms that are firm, dry, and free of blemishes.
- Fresh Mozzarella: 8 ounces/227 grams, preferably fresh mozzarella balls (bocconcini), halved or quartered if large. This provides the quintessential creamy, milky flavor.
- Cherry Tomatoes: 1 pint (about 10 ounces/283 grams), halved. Look for vibrant, ripe cherry tomatoes for the best flavor.
- Fresh Basil: 1/4 cup, chopped. Fresh basil is essential for that classic Caprese aroma and taste.
- Olive Oil: 2 tablespoons, extra virgin. Use a good-quality olive oil for the best flavor.
- Balsamic Glaze: 2 tablespoons. This adds a touch of sweetness and tang that perfectly complements the other ingredients. You can find this pre-made or make your own by simmering balsamic vinegar until it thickens.
- Garlic: 2 cloves, minced (optional). Adds a layer of savory depth. If you use garlic, use fresh garlic cloves.
- Salt & Pepper: To taste. Season generously to bring out the flavors of the ingredients.
Kitchen Tools Needed
- Baking Sheet: For roasting the stuffed portobello mushrooms.
- Parchment Paper (Optional): For easy cleanup.
- Chef’s Knife: For chopping vegetables and herbs.
- Cutting Board: For preparing the ingredients.
- Small Bowl: For mixing the filling ingredients.
- Spoon: For filling the mushroom caps.
(How to Make Stuffed Portobello Mushrooms (Step-by-Step Instructions)
- Preheat the Oven: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup (optional).
- Prepare the Mushrooms: Gently remove the stems from the portobello mushrooms. Use a spoon to scrape out the dark gills from the underside of the caps (this prevents them from becoming soggy). Pat the mushrooms dry with a paper towel.
- Season the Mushrooms: Brush the inside and outside of the mushroom caps with olive oil. Season with salt and pepper.
- Mix the Filling: In a small bowl, combine the halved cherry tomatoes, fresh mozzarella, minced garlic (if using), and chopped basil. Toss gently to combine while prepping the fantastic stuffed portobello mushrooms.
- Fill the Mushrooms: Spoon the Caprese filling into the mushroom caps, dividing it evenly among the four mushrooms.
- Bake the Mushrooms: Place the stuffed mushrooms on the prepared baking sheet, and bake for 15-20 minutes, or until the mushrooms are tender and the cheese is melted and slightly golden. The edges of the mushrooms should be slightly golden brown, and the center will be slightly jiggly.
- Drizzle with Balsamic Glaze: Remove the baking sheet from the oven and drizzle each stuffed portobello mushroom with balsamic glaze.
- Serve and Enjoy: Serve immediately, while the mushrooms are warm and the cheese is melty. Garnish with extra fresh basil, if desired.
Pro Tips for Success
- Don’t Overcrowd the Baking Sheet: Leave enough space between the mushrooms on the baking sheet so that they can roast properly. Overcrowding will steam the mushrooms instead of roasting them.
- Choose the Right Size Mushrooms: Select portobello mushrooms that are large enough to hold a generous amount of filling, but not so large that they take too long to cook.
- Drain Excess Moisture: If your mozzarella is particularly watery, drain it well before using it in the filling to prevent the mushrooms from becoming soggy.
- Adjust Cooking Time as Needed: The cooking time may vary depending on the size and thickness of the mushrooms. Check them frequently and adjust the cooking time accordingly.
- Use High-Quality Ingredients: The quality of the ingredients will directly impact the flavor of the dish. Use the freshest, best-quality ingredients you can find.
Variations & Dietary Swaps
- Add Protein: Add cooked Italian sausage, ground turkey, or grilled chicken to the filling for a heartier meal.
- Different Cheese: Experiment with different cheeses like provolone, fontina, or ricotta.
- Spicy Kick: Add a pinch of red pepper flakes to the filling for a little heat.
- Vegan Option: Use vegan mozzarella and a vegan balsamic glaze to make this recipe completely plant-based. Nutritional yeast can add a “cheesy” flavor.
- Gluten-Free: This recipe is naturally gluten-free.
