Introduction

These Easy Gluten-Free Longhorn Stuffed Mushrooms are a perfect appetizer or snack that’s both flavorful and simple to make. Packed with creamy cheese and a hint of garlic, they offer a delicious bite that everyone can enjoy, especially those avoiding gluten.

The image shows a white scalloped baking dish filled with stuffed mushrooms arranged closely in three rows, each mushroom topped with creamy melted cheese in an off-white color with a golden brown crispy layer of breadcrumbs on top and small green herb sprinkles. The mushrooms have a rich dark brown color, and the cheese layer melts down the sides, sitting in a light brown sauce pooling at the bottom of the dish. One mushroom is being lifted by a silver ornate spoon, showing the melted cheese stretching slightly. The dish is placed on a white marbled surface with a light gray cloth partially visible underneath the dish. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

16 white button or baby portobello mushrooms
1 cup sharp white cheddar cheese, shredded
4 oz cream cheese, softened
1/4 cup gluten-free Alfredo sauce
1/4 cup gluten-free panko breadcrumbs
2 tbsp garlic herb cream cheese (optional for extra flavor)
1/2 tsp garlic powder
1/2 tsp onion powder
Salt and pepper to taste
Fresh parsley for garnish

Instructions

Step 1: Preheat the oven to 375°F (190°C).
Step 2: Clean mushrooms gently with a damp cloth and remove the stems.
Step 3: Chop the stems finely and set aside.
Step 4: In a bowl, mix shredded cheddar, softened cream cheese, Alfredo sauce, garlic herb cream cheese (if using), garlic powder, onion powder, and chopped mushroom stems. Season with salt and pepper.
Step 5: Chill the filling in the refrigerator for 20 minutes to firm up.
Step 6: Stuff each mushroom cap with the chilled filling and top with gluten-free panko breadcrumbs.
Step 7: Bake for 20 to 25 minutes until the filling is hot and bubbly and the tops are golden brown.
Step 8: For extra crispness, broil the mushrooms for an additional 2 minutes, watching carefully to avoid burning.
Step 9: Garnish with fresh parsley and serve warm.

Tips & Variations

For a richer flavor, try adding a sprinkle of Parmesan cheese to the filling.
Use different mushroom varieties, like cremini, for a deeper taste.
If you can’t find gluten-free panko, crushed gluten-free crackers can be a good substitute.
Make them vegetarian by ensuring your Alfredo sauce is vegetarian-friendly or substitute with a homemade white sauce.

Storage

Store leftover stuffed mushrooms in an airtight container in the refrigerator for up to 2 days. Reheat gently in the oven at 350°F (175°C) for about 10 minutes to maintain their texture. Avoid microwaving as it can make the mushrooms soggy.
