Longhorn Stuffed Mushrooms Ingredients

For the Mushrooms

Mushrooms (16 oz) – The star of the show, providing a sturdy base and earthy flavor; portobello or baby bella work great for variety.
Coarse Sea Salt (1/4 tsp) – Enhances the flavor of the mushrooms; feel free to substitute regular salt but adjust accordingly.
Black Pepper (1/4 tsp) – Adds a hint of warmth; adjust to your taste preference.

For the Stuffing

Breadcrumbs (1/4 cup) – Provides that perfect crunch; gluten-free breadcrumbs can be used for an alternative.
Butter (3 tbsp + 3 tbsp) – Riches up the mixture and helps bind it; olive oil can be a great plant-based option.
White Cheddar Cheese (1.5 cups, grated) – The creamy heart of this dish, giving it that irresistible cheesy flavor; Gruyère or vegan cheese works well as substitutes.

For the Alfredo Sauce

Butter (3 tbsp, salted) – Essential for building a luscious sauce base.
Minced Garlic (1 tsp) – Infuses depth into the Alfredo; fresh garlic is highly recommended for the best flavor.
Flour (2 tsp) – Helps thicken the sauce; cornstarch is a gluten-free alternative.
Half and Half (1 1/3 cup) – Creates a creamy texture; swap with a dairy-free creamer if desired.
Parmesan Cheese (2/3 cup, grated) – Takes the umami flavor to new heights; nutritional yeast works for a vegan option.

These Longhorn Stuffed Mushrooms are not only delicious but also cater to various dietary preferences, making them the perfect appetizer for any occasion!

Step‑by‑Step Instructions for Longhorn Stuffed Mushrooms

Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While the oven is heating up, grab a cast iron skillet and lightly spray it with nonstick cooking spray. This will ensure your Longhorn Stuffed Mushrooms cook evenly and don’t stick to the pan, setting the stage for a perfect bake.

Step 2: Clean and Stem the Mushrooms
Take your 16 oz of mushrooms and gently clean them using a damp paper towel, removing any dirt. Carefully twist off the stems, creating a cavity for the stuffing. This is crucial for a great texture; you want the juicy mushroom caps ready to hold in all that cheesy goodness, so set them aside on a platter.

Step 3: Create the Stuffing Mix
In a mixing bowl, combine the breadcrumbs, melted butter (3 tbsp), coarse sea salt, and black pepper. Stir the mixture until the breadcrumbs are fully coated in butter, providing a delightful crunch for your Longhorn Stuffed Mushrooms. Once combined, set this mixture aside for later use.

Step 4: Make the Alfredo Sauce
In a skillet, melt the remaining 3 tbsp of butter over medium heat. Add the minced garlic, sautéing for about 1 minute until fragrant. Then, sprinkle in the flour and stir continuously to create a roux. Gradually whisk in the half and half, followed by the grated Parmesan cheese, allowing the sauce to thicken into a creamy texture, which will be poured over your stuffed mushrooms.

Step 5: Assemble the Mushrooms
Layer half of the creamy Alfredo sauce into the bottom of your prepared skillet. Carefully place the mushroom caps on top, making sure each cap is well-positioned to catch the sauce. Spoon the remaining Alfredo sauce generously over each mushroom, ensuring they are generously coated in cheesy goodness, ready for the final touches.

Step 6: Add Cheese and Breadcrumbs
Sprinkle the grated white cheddar cheese over the top of each mushroom, creating a deliciously gooey topping. Finally, take your reserved breadcrumb mixture and distribute it evenly across all the stuffed mushrooms. This will create that desired golden brown crunch on top while baking.

Step 7: Bake to Perfection
Place the skillet in the preheated oven and bake for about 10 minutes. After this initial bake, switch to the broil setting for an additional 2–3 minutes. This step will achieve that beautifully crisp breadcrumb topping, so keep a close eye to prevent burning as you watch for golden brown perfection.

Step 8: Garnish and Serve
Once baked, remove the skillet from the oven and let the Longhorn Stuffed Mushrooms cool slightly. As a final touch, sprinkle freshly chopped parsley over the top for a burst of color and freshness. Serve warm and watch your guests delight in every cheesy, savory bite!

Make Ahead Options

These Longhorn Stuffed Mushrooms are a fantastic choice for meal prep! You can prepare the stuffing and Alfredo sauce up to 24 hours in advance, storing them separately in airtight containers in the refrigerator. Just assemble by spooning the sauce over the stuffed mushrooms when you’re ready to bake. For optimal quality, ensure that the mushroom caps are patted dry before stuffing, preventing any unnecessary moisture. This way, when it’s time to serve, you simply need to bake for about 10 minutes, then broil for 2-3 minutes, achieving that delicious golden crunch without the fuss of starting from scratch. Enjoy the convenience and flavor with this make-ahead method!

Expert Tips for Longhorn Stuffed Mushrooms

Dry Your Mushrooms: Ensure mushrooms are well-patted dry before stuffing. This prevents excess moisture, keeping your Longhorn Stuffed Mushrooms from becoming soggy.
Watch the Broiler: Keep a close eye on the mushrooms while broiling. The breadcrumbs can go from golden to burnt quickly, so stay attentive for perfect results.
Cheese Grating Trick: Use a rotary cheese grater for quick and efficient cheese preparation. It makes grating white cheddar cheese a breeze and ensures even melting.
Modify Texture: For a creamier stuffing, consider adding softened cream cheese or ricotta along with the white cheddar. This adds a delightful richness to your Longhorn Stuffed Mushrooms.
Flavor Boosting: Don’t hesitate to sprinkle in some Italian herbs or fresh chopped parsley into your stuffing mix for an extra flavor kick; it elevates the taste without much effort.
