Step‑by‑Step Instructions for Crab Stuffed Mushrooms
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures a perfectly baked Crab Stuffed Mushrooms dish. As the oven heats up, gather your ingredients and equipment, including a baking sheet lined with foil for easy cleanup, and a large skillet for sautéing.
Step 2: Cook the Bacon
In a skillet over medium heat, cook 2-3 slices of bacon until crispy, about 5-7 minutes. Once cooked, transfer the bacon to a paper towel-lined plate to drain excess grease, allowing it to cool before chopping. This will add a savory crunch to your Crab Stuffed Mushrooms.
Step 3: Sauté the Garlic
Using the same skillet, discard some of the bacon grease, leaving about a tablespoon for flavor. Add a drizzle of olive oil and sauté 2-3 minced garlic cloves for 2-3 minutes until fragrant. Keep an eye on the garlic to prevent it from burning, as you want it to remain golden and aromatic.
Step 4: Cook the Spinach
Next, stir in a couple of cups of fresh spinach into the skillet with the sautéed garlic. Cook for about 2 minutes until the spinach wilts and reduces in volume, turning a vibrant green. This will infuse your Crab Stuffed Mushrooms with color and nutrients, making them deliciously appealing.
Step 5: Combine Crab and Seasonings
Check your crab meat for shells and gently fold it into the skillet with the spinach and garlic. Add a pinch each of onion powder, seasoning salt, and Old Bay seasoning for that iconic seafood flavor. Mix everything together for another 2-3 minutes, allowing the flavors to blend harmoniously.
Step 6: Prepare the Cheese Mixture
In a bowl, beat 8 ounces of cream cheese until smooth. Stir in the crab and spinach mixture along with half a cup of Parmesan cheese. This creamy filling will be the star of your Crab Stuffed Mushrooms, so make sure it’s thoroughly combined and creamy before filling the mushroom caps.
Step 7: Prepare the Mushroom Caps
Clean your mushroom caps gently with a damp paper towel to avoid waterlogging. Remove the stems if necessary, and place them upside down on your foil-lined baking sheet. These caps will cradle your crab stuffing perfectly, ensuring they bake beautifully and hold their shape.
Step 8: Stuff the Mushrooms
Using a small spoon or your hands, fill each mushroom cap with 1-1.5 tablespoons of the crab filling, mounding it slightly for a generous portion. Top each stuffed mushroom with a light sprinkling of Parmesan cheese, readying them for the oven and adding a deliciously cheesy crust.
Step 9: Bake to Perfection
Place the baking sheet in your preheated oven and bake the Crab Stuffed Mushrooms for about 15 minutes. They are done when the mushrooms are tender and the tops are lightly golden. Keep an eye on them towards the end for the perfect golden hue that signals they are ready to be devoured.
Step 10: Cool and Serve
Once baked, carefully remove the mushrooms from the oven and allow them to cool for about 10 minutes on a paper towel-lined plate. This cooling step helps absorb any excess moisture, ensuring your Crab Stuffed Mushrooms are perfect for serving at your next gathering or family meal.

Expert Tips for Crab Stuffed Mushrooms
