How to Make Longhorn Copycat Stuffed Mushrooms with Cheddar and Alfredo Recipe

Step 1: Prepare the Mushrooms

Start by preheating your oven to 375ºF and lightly spraying a cast iron skillet with nonstick spray. Gently clean the mushrooms by rubbing them with a damp paper towel to remove any dirt, then pat them dry. Carefully remove the stems and set the mushroom caps aside—they will become the perfect little bowls for your stuffing.

Step 2: Make the Breadcrumb Mixture

In a medium-sized mixing bowl, mix together the breadcrumbs, melted butter, sea salt, and black pepper. This buttery crumb topping will add a golden crunch that perfectly contrasts the creamy filling, so it’s worth ensuring this mix is just right and evenly coated.

Step 3: Whip Up the Alfredo Sauce

Using a small skillet over medium heat, melt the salted butter. Add the minced garlic and stir until fragrant—lower the heat and sprinkle in the flour to create a roux. Whisk constantly as you pour in the half and half and grated Parmesan cheese. Keep whisking until the sauce thickens to a creamy consistency and the cheese fully melts. This homemade Alfredo sauce is the secret to making these stuffed mushrooms irresistibly luscious.

Step 4: Assemble the Mushrooms

Pour half of the Alfredo sauce into the bottom of your prepared skillet. Nestle the mushroom caps on top of this creamy base. Spoon the remaining Alfredo sauce evenly over the mushrooms, then blanket each cap with a generous amount of shredded white cheddar cheese. Finally, sprinkle the buttered breadcrumb mixture over the top for that perfect crunch after baking.

Step 5: Bake to Perfection

Bake the mushrooms at 375ºF for 10 minutes. Then switch the oven to Broil Low and broil for 2 to 3 minutes until the breadcrumb topping turns golden brown and crispy. Keep a close eye during broiling to avoid burning. Once baked, let them cool slightly before serving.

Garnishes

A sprinkle of fresh, finely chopped parsley or chives adds a pop of color and a fresh herbal note that brightens these rich mushrooms beautifully. For an extra touch, a dusting of smoked paprika can add a whisper of smoky warmth that’s delightful.

Side Dishes

These decadent stuffed mushrooms pair wonderfully with light, crisp salads like a tangy arugula salad or a fresh tomato and cucumber salad to balance the richness. Alternatively, serve them alongside a simple pasta tossed with olive oil and garlic, or roasted vegetables for a complete meal.

Creative Ways to Present

Serve the mushrooms on a rustic wooden board lined with parchment for a charming, casual feel. For entertaining, place them in mini cupcake liners or on individual appetizer spoons for easy grab-and-go service. Even stacking a few with colorful garnishes on a white platter creates an inviting centerpiece.

Make Ahead and Storage

Storing Leftovers

Store any leftover Longhorn Copycat Stuffed Mushrooms with Cheddar and Alfredo Recipe in an airtight container in the refrigerator. They will keep well for up to 3 days, maintaining much of their creamy, cheesy goodness.

Freezing

While delicious fresh, these stuffed mushrooms can be frozen in a single layer on a baking sheet before transferring to a freezer-safe container. Freeze for up to 1 month. Thaw overnight in the fridge before reheating for best texture.

Reheating

Reheat leftovers in a preheated oven at 350ºF for about 10 minutes until warmed through. Avoid microwaving as this can make the breadcrumb topping soggy and the cheese separate. A quick broil at the end can restore that wonderful crunch.

FAQs

Can I use a different type of mushroom?

Absolutely! While white button mushrooms work best for their size and texture, cremini or baby portobellos can also be used for a deeper, earthier flavor.

Is this recipe vegetarian?

Yes, this Longhorn Copycat Stuffed Mushrooms with Cheddar and Alfredo Recipe is fully vegetarian as it contains no meat or meat broths, making it perfect for vegetarians craving a hearty starter.

Can I prepare the Alfredo sauce in advance?

Yes, the Alfredo sauce can be made a day ahead and refrigerated. Reheat gently on the stove with a splash of half and half to restore creaminess before assembling the mushrooms.

What can I substitute for half and half in the sauce?

You can use whole milk mixed with a bit of cream or even heavy cream alone for a richer sauce. For lighter options, skim milk works, but the sauce will be less creamy.

How do I make the breadcrumbs crispy?

Mixing the breadcrumbs with melted butter before topping the mushrooms ensures they crisp up nicely during baking and broiling, adding a perfect crunchy layer.
