Stuffed Asiago-Basil Mushrooms

The smell of garlic and basil hit me the second I opened my friend Maria's oven, and I knew I was about to taste something I'd be making for years. She pulled out a tray of golden-topped mushrooms, their edges crisp and bubbling with melted Asiago, and handed me one still too hot to hold comfortably. I didn't care. That first bite—creamy, herbaceous, with just enough bite from the cheese—made me grab a napkin and ask for the recipe immediately. She laughed and said it was the easiest thing she made all week, which only made me love it more.

I made these for a book club meeting once, mostly because I had a flat of mushrooms from the farmers market that needed using. Three people asked for the recipe before we even started discussing the book, and one friend texted me the next day to say she'd already made them twice. They've become my go-to whenever I need to bring something that feels special but doesn't require me to miss the actual gathering because I'm stuck in someone's kitchen.

Ingredients

• Cremini or white button mushrooms: I prefer cremini for their deeper flavor, but white buttons work beautifully and are often cheaper; just make sure they're all similar in size so they cook evenly.
• Olive oil: This goes into the filling and over the tops, adding richness and helping everything turn golden and gorgeous in the oven.
• Reserved mushroom stems: Don't toss these—they add earthy flavor and bulk to the filling without any waste, plus they help the stuffing hold together.
• Garlic: Two cloves might sound modest, but once they soften in the oil with the mushroom stems, they perfume the entire filling without overpowering the basil.
• Asiago cheese: This is the star; it's got a nutty sharpness that melts into the cream cheese and creates that irresistible savory pull.
• Cream cheese: Softened cream cheese binds everything together and gives the filling a luscious, almost mousse-like texture.
• Panko breadcrumbs: These add just enough structure to keep the filling from being too soft, and they crisp up beautifully on top.
• Fresh basil: This is non-negotiable for me; dried basil just doesn't bring the same bright, sweet fragrance that makes these mushrooms sing.
• Fresh parsley: It adds a subtle freshness and a pop of color that makes the filling look as good as it tastes.
• Black pepper and salt: Just enough to enhance everything without competing with the cheese.

Instructions

Get the oven ready:

Preheat your oven to 375°F and line a baking sheet with parchment paper so cleanup is a breeze. This also keeps the mushrooms from sticking and makes them easy to transfer to a serving platter.

Prep the mushrooms:

Gently twist out the stems and set them aside, then use a damp towel to wipe any dirt off the caps. Don't rinse them under water or they'll get soggy and won't crisp up nicely in the oven.

Cook the stem mixture:

Chop the stems finely, then sauté them with the garlic in a tablespoon of olive oil over medium heat for about 3 to 4 minutes. You want the moisture to cook off and the garlic to turn fragrant and soft, not browned.

Make the filling:

Let the stem mixture cool for a minute, then stir it into a bowl with the Asiago, cream cheese, breadcrumbs, basil, parsley, pepper, and salt. Mix it until everything is evenly combined and the mixture holds together when you scoop it.

Stuff the caps:

Use a spoon to fill each mushroom cap generously, pressing the filling in lightly so it stays put. Don't be shy—these should look abundant and inviting on the tray.

Finish and bake:

Drizzle the stuffed mushrooms with a tablespoon of olive oil and sprinkle the remaining Asiago over the tops. Bake for 18 to 20 minutes, until the mushrooms are tender and the tops are golden and bubbling.

Serve:

Let them cool for a few minutes so no one burns their tongue, then garnish with a few torn basil leaves if you have them. They're wonderful warm, but they also hold up at room temperature if you need to make them ahead.

There's a moment when these come out of the oven and everyone gravitates toward the kitchen without even realizing it. The smell does all the work—garlic, cheese, herbs—and suddenly people are standing around the tray with napkins, reaching for just one more. I've stopped plating these on anything fancy because they never make it that far anyway.

Make Ahead Magic

You can stuff these mushrooms up to six hours before you plan to bake them, cover the tray with plastic wrap, and keep them in the fridge. When it's time, just pull them out, add the oil and cheese topping, and slide them into the oven. I've done this for dinner parties more times than I can count, and it always buys me an extra hour to actually enjoy my guests instead of panicking in the kitchen.

Flavor Swaps

If you can't find Asiago or just want to try something different, Parmesan or Pecorino Romano both work beautifully and bring their own sharpness to the filling. I've also swapped the basil for fresh thyme when I had a bunch growing wild in the garden, and it gave the mushrooms a more earthy, rustic vibe that paired perfectly with roasted chicken. You can also add a pinch of red pepper flakes to the filling if you like a little heat, though I usually skip it when I'm serving a crowd.

Serving and Pairing

These mushrooms are my favorite thing to serve with a crisp, cold Pinot Grigio or even a dry sparkling wine if I'm feeling celebratory. They also sit beautifully on a platter next to cured meats, olives, and a simple green salad for a light lunch or appetizer spread. If you're serving them as part of a larger meal, they go especially well before pasta dishes or anything tomato-based, since the creamy filling offers a nice contrast.

• Arrange them on a wooden board with fresh herbs scattered around for a rustic, welcoming look.
• Serve them with toothpicks if it's a stand-up party, though they're sturdy enough to pick up with your fingers.
• Leftovers (if you're lucky enough to have any) reheat surprisingly well in a 350°F oven for about 8 minutes.

These little mushrooms have a way of turning any gathering into something that feels more intentional, more generous. Make them once, and I promise they'll become part of your rotation too.

Recipe FAQs

→ Can I prepare these mushrooms ahead of time?

Yes, you can assemble the stuffed mushrooms up to 24 hours in advance. Cover and refrigerate them, then bake just before serving. Add a few extra minutes to the baking time if cooking from cold.

→ What type of mushrooms work best for stuffing?

Medium cremini or white button mushrooms are ideal as they have sturdy caps that hold filling well. Look for mushrooms about 1.5 to 2 inches in diameter with firm, unblemished caps.

→ How do I prevent the mushrooms from becoming watery?

Sautéing the chopped stems until moisture evaporates is key. Also, avoid washing mushrooms under running water; instead, wipe them clean with a damp paper towel to prevent excess moisture.

→ Can I make these without breadcrumbs?

Absolutely. For a low-carb version, omit breadcrumbs and add extra cheese or finely chopped nuts like walnuts or almonds for texture. The filling will be creamier but equally delicious.

→ What can I substitute for Asiago cheese?

Parmesan, Pecorino Romano, or Gruyère make excellent substitutes. Each offers a slightly different flavor profile but maintains the savory, nutty character that complements the basil and garlic beautifully.

→ How should I store leftovers?

Store cooled stuffed mushrooms in an airtight container in the refrigerator for up to 3 days. Reheat in a 350°F oven for 8-10 minutes until warmed through and crispy on top.
