Ingredients

  • 18 large mushrooms
  • 2 1/2 dozen oysters, chopped
  • 1 clove garlic, crushed
  • 3 green onions, chopped
  • 1/2 cup bread crumbs
  • 2 tablespoons Parmesan or Romano cheese, grated
  • 4 tablespoons butter
  • 1 egg, beaten

Instructions

  1. Cut stems out of mushrooms, leaving a niche for stuffing. Saute mushroom caps in 2 tablespoons butter; set aside.
  2. Saute green onions, garlic, and chopped stems of mushrooms in 2 tablespoons butter.
  3. Add chopped oysters and cook until oysters curl.
  4. Add breadcrumb-Parmesan cheese mixture, then bind with the beaten egg. Stuff mushroom caps with the mixture.
  5. Place a slice of Cheddar cheese on top of each mushroom and put under the broiler for browning.

Tips & Substitutions

When preparing the mushrooms, ensure to remove the stems carefully to create enough space for the stuffing. If fresh oysters are unavailable, canned oysters can be a convenient substitute. To enhance flavor, consider adding a pinch of cayenne pepper or Old Bay seasoning to the mixture. Pairing these stuffed mushrooms with sides like a simple salad or roasted vegetables can balance the richness of the dish. Browse more American recipes for inspiration.

Serving Suggestions

Serve the oyster stuffed mushrooms as an elegant appetizer or as part of a seafood spread. They pair wonderfully with a light salad or a refreshing Lobster Salad to complement the flavors. For a complete meal, consider serving alongside Grandmom Strouse'S Macaroni Salad for a delightful contrast in texture and taste.

Storage & Reheating

Store any leftover stuffed mushrooms in an airtight container in the refrigerator for up to 3 days. To reheat, place them in an oven preheated to 350°F (175°C) for about 10-15 minutes, or until heated through. This method will help retain their texture and prevent them from becoming soggy.

Frequently Asked Questions

Can I prepare these stuffed mushrooms in advance?

Yes, you can prepare the stuffing a day ahead and fill the mushrooms just before baking. Store the filled mushrooms in the refrigerator covered with plastic wrap. This allows the flavors to meld, making them even tastier when baked.

What type of cheese can I use instead of Cheddar?

If you're looking for alternatives to Cheddar, Gruyère or mozzarella cheese work beautifully for topping these mushrooms. Both cheeses melt well and add a creamy texture that complements the oyster filling.

Can I make this recipe gluten-free?

Certainly! To make the oyster stuffed mushrooms gluten-free, simply substitute regular bread crumbs with gluten-free bread crumbs or crushed gluten-free crackers. This modification will maintain the texture while accommodating dietary restrictions.
