Let me tell you about my go-to crowd-pleaser that always gets compliments. These White Cheddar Stuffed Mushrooms taste identical to Longhorn Steakhouse's version but made in your own home. Once you bite into that velvety white cheddar filling with its crispy Parmesan topping, you'll see why friends constantly ask me how I make them.
What Makes These Taste Authentically Delicious
After countless attempts to duplicate those fantastic Longhorn mushrooms, I finally nailed it. The mix of creamy white cheddar, crunchy golden parmesan and juicy mushrooms creates something truly wonderful. And guess what? They're way simpler to whip up than they look.
Shopping List Essentials
- Mushrooms: Baby bellas work best because they stay firm when cooked.
- White Cheddar: Don't skimp here—buy quality cheese for best results.
- Garlic and Herb Pub Cheese: This hidden ingredient brings all the amazing flavor.
- Parmesan: Grab it freshly grated for that perfect golden top.
- Wine: Just pour some of whatever white you'll enjoy with your meal.
- Breadcrumbs: They're not required but add such a nice texture.
Prepping Your Mushrooms
Let's start with getting those mushrooms ready. Just gently clean them with a paper towel instead of washing them so they won't soak up water. Remove the stems but keep them handy for our filling. I find using a small knife around each stem makes them pop right out.
Whipping Up The Delectable Filling
Here comes the best part—creating that irresistible filling. Mix your white cheddar, pub cheese and a bit of wine together, then add those finely diced mushroom stems. The mixture should be smooth enough to spoon easily. I usually steal a tiny taste to check it's just right.
Filling The Caps
Take your prepared mushroom caps and begin stuffing each one gently. Don't pack them too full since the filling will expand during baking. A small spoon works great for getting just the right amount into every mushroom.
Baking To Perfection
Cover your baking tray with foil or parchment to make your life easier later. Put your stuffed treasures in a 375°F oven and cook for around 15-20 minutes. Your home will fill with wonderful aromas as they bake. You'll know they're done when the tops turn golden and mushrooms are soft but still intact.
Tricks I've Learned
From making these tons of times, I've picked up a few things. Always buy good cheese because it really affects the taste. I store leftover mushroom stems in my freezer for when I make soup. And let them sit a minute before serving so nobody burns their mouth.
My Best Tips
After making these countless times here's what I've learned. Always use good quality cheese it really shows in the final taste. I save those extra mushroom stems in the freezer for soups. And let them cool just a bit before serving nobody likes a burnt tongue.

Prepare Them In Advance
These work great for parties because you can fix them beforehand. You can make them up to two days early and store covered in your fridge. You can even freeze them uncooked and put them straight from freezer to oven when needed.
Reheating Instructions
When cooking frozen ones, just add about 15 more minutes to your baking time. Watch them carefully until the top gets nice and bubbly. They taste just as wonderful as when you make them fresh.
Perfect Party Presentation
I always serve these at gatherings with a nice glass of white wine. They fit everything from fancy dinners to casual hangouts. Sometimes I make twice as many because they vanish so fast.
The Universal Appeal
There's something about small bites that just makes everyone smile. These stuffed mushrooms blend fancy and cozy in one perfect package. Whenever I serve them, someone wants to know how I made them, and I love letting friends in on this bit of restaurant magic they can cook at home.
