Hi I’m Jo-Anna from A Pretty Life in the Suburbs, and I’m back to share a delicious holiday appetizer recipe with you! This is the time of year we’re all busy planning holiday get togethers with friends, and this means we need recipe ideas! I’m always on the look out for easy and delicious appetizer ideas, so I thought I’d share one with you today.
This is a recipe for Mushroom, Herb & Gruyere Cheese Mini Turnovers, and oh man are they good! These bite-sized turnovers will disappear from your appetizer table before you know it … they’re bursting with flavours of herbs and tangy cheese. Even the so-called ‘mushroom haters’ in my household loved these. In fact, I saw them go back for seconds and thirds. They’re too good to resist. I think it’s the cheese and the addition of cream and Chardonnay takes these turnovers to the next level.
What Are Mini Turnovers?
A turnover is a piece of dough folded over a filling and baked until golden. Nearly every food culture has its own version, from Latin American empanadas to British pasties to Italian calzones, and the classic turnover can be sweet or savory depending on what you tuck inside. The mini version is where things get really fun. Shrink a turnover down to two or three bites and you have the ideal party appetizer, easy to pass around and far more impressive than the effort involved.
The real secret is puff pastry. Store-bought puff pastry is one of the best shortcuts a home cook can keep in the freezer, delivering that beautiful, buttery, layered rise without any of the folding and chilling that homemade requires.
The Best Mushrooms to Use for Turnovers
Cremini mushrooms are the classic choice for this recipe, and for good reason. They have a deeper, earthier flavor than white button mushrooms and hold up beautifully once cooked down with butter and herbs. But if you want to play around with the filling, this recipe is a great canvas for other varieties too.
- Baby bella mushrooms are essentially cremini's slightly more mature cousin and can be swapped in one-for-one. Expect a similar texture with a touch more depth.
- Shiitake mushrooms bring a meatier, more umami-forward flavor that pairs especially well with the nuttiness of the Gruyere. Remove the tough stems before chopping, since they don't soften the way the caps do.
- Oyster mushrooms are delicate, mild, and slightly sweet, with a velvety texture once sautéed. They cook faster than cremini and give the filling a more refined, almost buttery quality.
- A wild mushroom blend is the move if you really want to elevate this appetizer. A mix of chanterelles, porcini, maitake, and shiitake creates a filling that tastes layered and complex, and it's especially lovely for a holiday party where you want the food to feel a little special.
Why Gruyere Is the Perfect Cheese for This Filling
Gruyere is the kind of cheese that seems built for recipes like this one. It's nutty, slightly sweet, and has just enough tang to cut through the richness of the cream without overpowering the earthy mushrooms or fresh herbs. It also melts like a dream, turning silky and stretchy the moment it hits the warm filling, which is exactly what you want inside a flaky puff pastry pocket.
There's also a reason Gruyere shows up so often in classic French cooking. It's aged long enough to develop real depth of flavor, so a little goes a long way. Just a third of a cup shredded into the filling adds a savory backbone that ties the mushrooms, thyme, and rosemary together into something that tastes far more complex than the short ingredient list suggests.
If you can't find Gruyere at your grocery store, a few substitutes work beautifully:
- Comté is the closest match, with a similar nutty, buttery profile and excellent melt.
- Emmental brings a milder, slightly sweeter flavor and still melts smoothly.
- Sharp white cheddar is the easiest pantry swap and adds a bolder, tangier bite that works especially well with the mushrooms.
How to Work with Puff Pastry Like a Pro
Puff pastry is one of the most forgiving ingredients in the freezer aisle, but it does have a few rules. Get them right and you'll be rewarded with tall, golden, shatteringly flaky turnovers every time.
The most important thing to remember is that puff pastry loves the cold. Those beautiful layers you see in the finished pastry come from tiny pockets of butter trapped between sheets of dough. When the pastry hits the hot oven, that butter turns to steam and pushes the layers apart, which is where the "puff" comes from. If the butter melts before it hits the oven, you lose the rise. Keep the dough cold at every step, and if it starts to feel soft or sticky while you're working, pop it back in the fridge for 10 minutes and pick up where you left off.
A few more tips that make a real difference:
- Thaw it slowly. The best way to defrost puff pastry is overnight in the refrigerator. If you're short on time, 30 to 40 minutes on the counter usually does the trick. Skip the microwave, which will make the butter uneven.
- Roll gently and evenly. Puff pastry doesn't need much rolling, just enough to smooth out the seams and even the thickness. Use a light touch, and always roll on a lightly floured surface so nothing sticks.
- Seal the edges well. After filling each turnover, press the edges firmly with your fingers or crimp them with a fork. A tight seal keeps the filling inside and prevents leaks in the oven.
- Don't skip the egg wash. Brushing the tops with a whisked egg-and-water mixture is what gives puff pastry that signature golden, glossy finish. Coat every visible surface, but avoid pooling any wash along the sealed edges, since it can glue the layers shut and prevent the pastry from puffing.
- Bake in a hot oven. Puff pastry needs high heat to rise properly. A 400°F oven is the sweet spot for these turnovers, and you'll know they're done when the tops are deeply golden and the layers look visibly puffed.
One last pro move: give the turnovers plenty of space on the baking sheet. Crowded pastries steam each other instead of crisping, and that flaky finish is half the reason we love them.

What Wines to Serve with Mushroom and Gruyere Turnovers
The Chardonnay in the filling is a natural place to start when you're pouring for the party. Kendall-Jackson Vintner's Reserve Chardonnay, with its bright acidity, notes of tropical fruit and citrus, and gentle touch of oak, mirrors the flavors already in the pan and lifts the richness of the cream and cheese. For a rounder, more layered pour, Kendall-Jackson Grand Reserve Chardonnay leans into deeper notes of baked apple, lemon curd, and toasted oak that stand up beautifully to the melted Gruyere.
If you'd rather serve a red, Kendall-Jackson Vintner's Reserve Pinot Noir is the classic pick. Mushrooms and Pinot Noir have an almost magnetic pull toward each other, and its bright red-fruit character, silky texture, and soft tannins echo the earthiness of the filling without overwhelming the flaky pastry. It's the kind of bottle that plays nicely with every other appetizer on the board, which makes it an easy choice for a holiday party.
