Tips and Variations
Tips for Perfecting Mushrooms Neptune
- Choose fresh and large mushroom caps: Bigger mushrooms hold the Neptune filling better, creating a more impressive presentation.
- Clean mushrooms gently: Use a damp cloth or soft brush to remove dirt, avoiding soaking them in water to prevent sogginess.
- Pre-bake mushrooms: Baking the caps for about 10 minutes at 375°F (190°C) helps them soften while retaining firmness, ensuring they don’t collapse under the filling.
- Make a smooth roux: Whisk butter and flour constantly over medium heat to avoid lumps, which will create a creamy Neptune sauce base.
- Use lump crab meat for best flavor and texture: Avoid pre-flaked or canned crab that can become mushy.
- Season the sauce liberally: Incorporate Old Bay seasoning, garlic powder, and fresh parsley to enhance the seafood and mushroom synergy.
- Sprinkle freshly grated Parmesan: A final layer of Parmesan cheese guarantees a golden, bubbling crust after baking.
- Serve immediately: Mushrooms Neptune tastes best fresh from the oven while the sauce is warm and creamy.

| Spicy Kick | Add a pinch of cayenne pepper or hot sauce to the sauce for a spicy version | Balance heat with extra cream or milk in the roux |
