Grilled Stuffed Portobello Mushrooms Ingredients
- 4 large portobello mushrooms, stems removed
- 1/2 cup Italian breadcrumbs
- 1/4 cup parmesan cheese, grated
- 1/4 cup cream cheese, softened
- 2 cloves garlic, minced
- 2 tbsp fresh basil, chopped
- 2 tbsp olive oil
- 1 tbsp balsamic vinegar
- Salt and pepper to taste
How to Make Grilled Stuffed Portobello Mushrooms
- 1
Preheat grill to medium heat. Gently scrape the gills out of the mushroom caps using a spoon; this prevents the mushrooms from becoming watery and muddy-tasting. Brush the caps inside and out with olive oil and season with salt and pepper.
- 2
In a bowl, combine the breadcrumbs, parmesan cheese, cream cheese, garlic, basil, remaining olive oil, and balsamic vinegar. Mix until it forms a cohesive paste. The cream cheese binds the filling while the breadcrumbs provide texture.
- 3
Place the mushroom caps on the grill, gill-side up. Grill for 5 minutes to soften the caps. This initial sear starts the cooking process so the filling doesn't burn before the mushroom is done.
- 4
Remove caps from the grill (or carefully flip them on a tray) and divide the filling mixture evenly among the caps, pressing it down gently.
- 5
Return the stuffed mushrooms to the grill, gill-side up. Close the lid and cook for another 10-12 minutes, or until the mushrooms are tender and the filling is golden brown and bubbly.
- 6
Remove carefully using a spatula. Garnish with extra fresh basil and serve immediately.
Chef's Tips
- Bloom aromatics for 30–60 seconds before adding liquids to unlock deeper flavor in Grilled Stuffed Portobello Mushrooms.
- Cook the main protein or core ingredient in batches if needed—overcrowding lowers pan heat and prevents proper browning.
- Reserve a small amount of cooking liquid to adjust texture at the end and keep the final result glossy, not dry.
- Finish with contrast: add a fresh element (herbs/citrus/crunch) right before serving to sharpen the overall flavor profile.
