Ingredients
1 1/2 lbs baby bella mushrooms, cleaned and stems removed
2 tbsp olive oil
3 tbsp butter, divided
1 medium onion, finely diced
3 cloves garlic, minced
1/4 tsp crushed red pepper flakes (optional)
1/2 tsp salt
1/2 tsp black pepper
1/2 tsp dried thyme
1/2 tsp smoked paprika
1/4 cup dry white wine (or vegetable broth)
1/2 cup cream cheese, softened
1/2 cup sour cream
1 cup shredded mozzarella cheese
1/2 cup grated Parmesan cheese
1 1/2 cups seasoned breadcrumbs (Panko preferred)
2 tbsp chopped fresh parsley
Cooking spray or butter for greasing dish
Instructions
1. Clean mushrooms by gently wiping them with a damp cloth. Remove and finely chop the stems; set aside.
2. Heat olive oil and 1 tbsp butter in a skillet over medium heat. Add onions and cook 3–4 minutes until translucent.
3. Add garlic, chopped mushroom stems, red pepper flakes, thyme, paprika, salt, and pepper. Cook until fragrant and caramelized, about 5–6 minutes.
4. Pour in the wine or broth, scraping the skillet to deglaze. Simmer for 2 minutes.
5. Lower heat, stir in cream cheese and sour cream until fully melted and smooth.
6. Remove from heat and mix in mozzarella and half of the Parmesan. Stir in parsley and adjust seasoning.
7. Grease a 9×13-inch baking dish. Layer in mushroom caps and spoon the creamy mixture over them.
8. Mix breadcrumbs with melted butter and the remaining Parmesan. Spread evenly over the top.
9. Bake at 375°F (190°C) for 25–30 minutes until golden and bubbly.
10. Let rest for 5–10 minutes before serving. Garnish with more parsley.
Notes
Use fresh mushrooms and wipe them instead of rinsing to avoid sogginess.
Add breadcrumbs just before baking to maintain the perfect crunch.
For a meatier version, stir in cooked sausage or ground turkey to the filling.
