Ingredients
- 4 large russet potatoes, scrubbed
- 2 tablespoons olive oil
- 1 tablespoon butter
- 1 small onion, finely chopped
- 2 cups mushrooms, chopped
- 3 cups fresh spinach, chopped
- 2 cloves garlic, minced
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/2 cup sour cream
- 1/4 cup milk
- 1 cup shredded cheddar cheese, divided
- 1/2 cup shredded mozzarella cheese
- 1/4 cup grated Parmesan cheese
- 2 tablespoons fresh parsley, chopped (optional, for garnish)

Instructions
- Preheat oven to 400°F (200°C). Pierce potatoes several times with a fork, place on a baking sheet, and bake for 50–60 minutes, until tender when pierced with a knife.
- Remove potatoes from oven and let cool slightly. Slice each potato in half lengthwise. Carefully scoop out the insides into a bowl, leaving a thin shell.

- Mash the scooped potato flesh with sour cream, milk, half the cheddar cheese, and the mushroom-spinach mixture until smooth and creamy.
- Spoon filling back into potato shells. Place stuffed potatoes on a baking sheet.
- Top with remaining cheddar, mozzarella, and Parmesan cheeses.
- Bake for 15–20 minutes, until cheese is melted and bubbly.
- Garnish with parsley and serve warm.
Tips for Success
Do not rush the aromatics; let them soften until sweet before you add liquids. Avoid crowding the pan so moisture can escape and browning can happen. Taste before serving and adjust salt, acid, and heat to your liking.
