Ingredients

• 450 grams Fresh white or cremini mushrooms
• 2 tablespoons Olive oil
• 1 medium Yellow onion, finely diced
• 2 cloves Garlic cloves, minced
• 120 grams Low-fat sour cream
• 100 grams Shredded mozzarella cheese
• 2 tablespoons Fresh parsley, finely chopped
• 60 grams Panko breadcrumbs
• 2 tablespoons Butter, melted
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper

Directions

Step 1

Preheat your oven to 190°C (375°F).

Step 2

Clean the mushrooms using a damp paper towel and slice them thinly.

Step 3

Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the diced onion and cook for 3-4 minutes until translucent.

Step 4

Stir in the minced garlic and cook for another 30 seconds, or until fragrant.

Step 5

Add the sliced mushrooms to the skillet. Cook for about 6-8 minutes, stirring occasionally, until the mushrooms release their moisture and start to brown.

Step 6

Season the mushroom mixture with salt and black pepper. Stir to combine, then remove the skillet from heat.

Step 7

In a mixing bowl, combine the cooked mushrooms and onions with the low-fat sour cream, shredded mozzarella cheese, and fresh parsley.

Step 8

Transfer the mixture into a lightly greased casserole dish, spreading it out evenly.

Step 9

In a small bowl, mix the panko breadcrumbs with the melted butter and the remaining 1 tablespoon of olive oil. Sprinkle this mixture evenly over the casserole to form a crispy topping.

Step 10

Place the casserole dish in the preheated oven and bake for 20-25 minutes, or until the top is golden brown and bubbling.

Step 11

Remove from the oven and let it cool for 5 minutes before serving. Garnish with a little extra parsley, if desired.
