This lobster and crab stuffed mushrooms recipe transforms simple mushroom caps into an elegant appetizer that never fails to impress at gatherings. The combination of sweet lobster meat, tender crab, and savory cheese creates appetizer perfection that disappears quickly from any serving platter.
I originally created these for a New Year's Eve party when I wanted something special yet approachable. The balance of seafood and cheese had everyone asking for the recipe before midnight even struck.
Ingredients

- Green onions: Provide a mild onion flavor with a pop of color to brighten the dish
- Shallots: Contribute subtle sweetness that enhances rather than overwhelms the delicate seafood
- Mozzarella cheese: Creates that irresistible stretchy cheese pull when served hot
- Monterey and Colby Jack cheeses: Add complexity and sharpness to balance the rich seafood
- Boursin cheese: Introduces a creamy herb element that brings everything together
- Panko bread crumbs: Create the perfect light crunch without becoming soggy

Step-by-Step Instructions
- Preparation and Cleaning:
- Preheat oven to 375°F ensuring proper temperature for even cooking. Gently clean mushrooms with a damp paper towel being careful not to soak them as mushrooms absorb water easily. Remove stems completely by twisting them out from the base making a perfect cavity for the filling. Brush baking sheet thoroughly with melted butter which prevents sticking and adds flavor to the mushroom bases.
- Creating the Filling:
- Combine panko crumbs with melted butter in a medium bowl until evenly moistened. This creates the perfect binding agent for your seafood. Add chopped lobster and crab meat ensuring even distribution throughout the mixture. Fold in garlic and onions which provide aromatic foundation without overpowering the delicate seafood. Incorporate shredded cheeses thoroughly saving about 1/4 cup of mozzarella for the final topping. Season the mixture with paprika and Cajun seasoning adjusting to taste depending on desired spice level.
- Filling and Baking:
- Arrange mushroom caps in a single layer on the buttered baking sheet with the cavity facing upward. Using a small spoon generously fill each mushroom cap allowing the filling to mound slightly above the rim. Press filling gently to ensure it adheres without compacting too firmly. Bake for 10 to 15 minutes until the tops become golden brown and cheese begins to bubble around the edges. For an extra special finish sprinkle reserved mozzarella on top and broil for 2 to 3 minutes until cheese becomes bubbly and lightly browned creating an irresistible finish.

The lobster is truly the star ingredient in this recipe. I discovered this by accident when I ran short on crab meat one holiday and supplemented with lobster. My father in law who typically avoids seafood couldn't stop eating them and requested I make them again for his birthday dinner the following month.
Make Ahead Options
These stuffed mushrooms can be prepared up to 24 hours in advance for stress free entertaining. Simply complete all steps up to the baking point then cover tightly with plastic wrap and refrigerate. When ready to serve remove from refrigerator 30 minutes before baking to allow them to come to room temperature which ensures even cooking. You may need to add 2 to 3 additional minutes to the baking time if cooking from chilled. The filling can also be made separately and stored in the refrigerator for up to two days making assembly quick before guests arrive.
Perfect Pairings
These luxurious stuffed mushrooms pair beautifully with sparkling wines like Prosecco or Champagne which cut through the richness while complementing the delicate seafood flavors. For a full appetizer spread serve alongside lighter options like bruschetta or a fresh vegetable platter to balance the richness. They also make an excellent first course before a seafood pasta or grilled fish entrée continuing the elegant seafood theme throughout your meal. For casual gatherings consider serving them alongside a crisp green salad dressed with a light lemon vinaigrette.
Economical Alternatives
While lobster and lump crab create the most luxurious version of this recipe budget friendly substitutions can still deliver impressive results. Consider using all crab meat or substituting part of the seafood with chopped cooked shrimp which provides similar sweetness at a lower cost. Imitation crab meat can work in a pinch though the texture and flavor will be noticeably different. During holiday seasons watch for seafood sales which often occur around Christmas and New Years when these ingredients are in higher demand. Purchasing frozen seafood when on sale and storing until needed can make this special appetizer more affordable for regular enjoyment.

These lobster and crab stuffed mushrooms are the perfect blend of elegance and simplicity, sure to be a favorite at every occasion.
Frequently Asked Questions
- → Can I prepare these stuffed mushrooms ahead of time?

- → What can I substitute for the lobster?
If lobster isn't available, you can use all crab meat or substitute with cooked shrimp. For a budget-friendly option, imitation crab meat (surimi) can work, though the flavor won't be as rich.
- → What side dishes pair well with these mushrooms?
These stuffed mushrooms work beautifully as an appetizer on their own, but can be paired with a light salad, crusty bread, or a glass of chilled white wine. For a more substantial meal, serve alongside grilled fish or a simple pasta dish.
- → Can I freeze these stuffed mushrooms?
Yes, you can freeze them before baking. Prepare the mushrooms completely, then freeze on a baking sheet until solid. Transfer to an airtight container and store for up to 3 months. When ready to serve, bake from frozen, adding 5-7 minutes to the cooking time.
- → What's the best way to clean mushrooms?
The best way to clean mushrooms is with a damp paper towel, gently wiping away any dirt. Avoid submerging mushrooms in water as they absorb moisture quickly and can become soggy when baked.
