Description
Delightful Crab Stuffed Portobello Mushrooms recipe can be baked and served as an appetizer or main dish.
Ingredients
- 4 large Portobello mushrooms, firm and free from blemishes
- 4 ounces reduced-fat cream cheese (Neufchatel), softened
- 8 ounces lump or jumbo crab meat, pasteurized
- 1 egg white, helps bind the filling
- 2 scallions, finely sliced, plus more for garnish
- 1/2 cup Panko breadcrumbs, plus 3 tablespoons, divided
- 1/2 cup grated Parmesan cheese, plus 1 tablespoon, divided
- 2 tablespoons finely chopped jarred and drained roasted red pepper or pimento
- 1 tablespoon melted salted butter, adds richness
- 1 1/21/2 teaspoons seafood seasoning blend such as Old Bay
- 1/41/2 teaspoon salt, optional
- Freshly ground pepper to taste
- 5 to 10 dashes of Tabasco hot sauce
- 1/81/2 teaspoon paprika
Instructions
- Prep the Mushrooms: Start by cleaning the portobello mushrooms gently with a damp cloth. Make sure to remove any dirt without soaking them in water, as that can make them soggy. They should feel firm and look shiny.
- Mix the Filling: In a bowl, blend the crab meat with softened cream cheese until smooth and creamy. This should feel velvety. Taste the mixture for seasoning; be cautious with salt, as you can always add more later.
- Stuff the Mushrooms: Spoon the crab mixture into each mushroom cap, ensuring they are nicely heaped. Avoid overstuffing, as it can burn during baking.
- Bake It Up: Slide the filled mushrooms into a preheated oven at 375 degrees F and bake until golden and the cheese is bubbly, approximately 30 minutes. A delightful aroma will fill your kitchen.
- Serve & Enjoy: Once removed from the oven, allow the mushrooms to sit for a few minutes. They will look inviting and are easier to serve after a short rest. Handle gently, as they can be delicate.
Notes
- Storage Tips: Refrigerate uneaten mushrooms in an airtight container at refrigerated temperatures for up to 2 days. Reheat in the microwave for about 90 seconds each. The filling can be mixed and frozen for up to 1 month but do not freeze stuffed mushrooms.
- Expert Tips: Use pasteurized crab meat for safety. Make sure your cream cheese is softened for easy mixing; let it sit at room temperature for about 30 minutes if needed. If the filling is too watery after baking, ensure the crab meat is well-drained and avoid excess moisture in the cream cheese.
- Reheating Instructions: Method: Microwave; Temperature: Medium; Timing: Heat for about 90 seconds each until thoroughly warmed.
- Serving Suggestions: Pair with Chopped Winter Salad or Roasted Asparagus. Complement with Steamed Cauliflower for a low-carb side.
- Recipe Variations: Substitute lump crab with shrimp or scallops for a different seafood flavor. For added spice, mix in chopped jalapeños. Use different cheese varieties like cheddar or feta for a unique twist.
- Ingredient Notes: Look for firm, blemish-free portobello mushrooms. If Panko breadcrumbs are unavailable, regular breadcrumbs can be used, though they will not provide the same crispiness.

Ingredient Notes
- Portobello mushrooms: These big guys are perfect for holding all that tasty filling. Look for ones that are firm and free from blemishes!
- Reduced-fat cream cheese: Softening it makes mixing a breeze, plus it adds that creamy richness. You could swap in regular cream cheese if you prefer.
- Seafood seasoning blend: This adds a punch of flavor to the filling! I love Old Bay, but feel free to try other blends if you like.
- Freshly ground pepper: Cracked pepper gives a nice kick! Adjust according to how spicy you want it, or leave it out if that’s your vibe.
- Tabasco hot sauce: Just a few dashes add some zing! You can use any hot sauce if you need, just check the heat level first.
- Egg white: Helps bind the filling together. If you’re keeping it vegan, a flax egg could be a good alternative!
- Scallions: These add a mild onion flavor and a pop of color. Go for fresh ones that’re bright green and firm!
- Panko breadcrumbs: They’re great for crunch! If you don’t have Panko, regular breadcrumbs work just fine, though they won’t be as crispy.
- Grated Parmesan cheese: Adds salty, nutty flavor to the filling and topping. You could use Pecorino Romano if you want a stronger taste.
- Roasted red pepper or pimento: These bring a nice sweetness and color. Fresh roasted can be swapped in if you want extra flavor.
- Lump or jumbo crab meat: This is the star! Look for pasteurized crab for safety, and if you can’t find it, canned crab works too.
- Melted salted butter: Adds richness to the filling and helps everything come together. If you want to skip dairy, try olive oil!
- Paprika: Just a pinch adds a nice depth of flavor and a bit of color. Smoked paprika is an awesome twist if you’re feeling adventurous!
Recipe Tips
- If the filling turns out too watery, making sure the crab meat is well-drained can help avoid excess moisture in the creamy mixture.
- When baking, selecting large, fresh portobello mushrooms is essential for tenderness; they’ll cook better if baked just until soft.
- For creamed filling that stays together, adding an additional egg white can work wonders to keep everything nicely bound.
- If seasoning feels off, sampling the mixture before adding extra salt is a great way to achieve just the right taste.
- If cream cheese is too firm to mix smoothly, letting it sit at room temperature for about 30 minutes will help it soften nicely.
Serving Suggestions
Recipe variations
- You can use shrimp or scallops instead of lump crab for a new seafood flavor in your Crab Stuffed Portobello Mushrooms.
- Add 1 finely chopped jalapeño to kick up the heat and flavor in this dish. It pairs wonderfully with seafood seasoning.
- Either swap the Parmesan for cheddar cheese or try feta for a creamier texture. Each option will add a unique twist.
- If you want to adjust the servings, use 6 large Portobello mushrooms, 12 ounces of crab meat, and scale the cheese accordingly.
