This is your weeknight superhero. It’s a free-form, rustic tart that says “I’m a culinary genius” but whispers “I used store-bought puff pastry.” It’s the ultimate vegetarian dinner that feels special, much like a comforting bowl of wild mushroom, caramelized onion, and kale soup.

Ultimate Guide to Spring Onion and Mushroom Galette
Why is this the only guide you need? Because I’m a busy cook just like you. I don’t have time for fussy steps.
This guide is built on three pillars: big flavor, crazy speed, and total ease. A galette is forgiving. No perfect circles needed. It’s a savory tart that welcomes imperfections.
The combo of earthy mushrooms and bright spring onions is magic. It’s rich and satisfying. And it all happens in about 40 minutes flat. Your future self will thank you.
The Simple Ingredients
Here’s the beauty part. You probably have half of this already. The rest is an easy grab at any store.
- 1 sheet store-bought puff pastry, thawed (our secret weapon!)
- 1 lb cremini or baby bella mushrooms, sliced
- 1 big bunch spring onions (about 6-8)
- 2 cloves garlic, minced
- 3 tbsp olive oil, divided
- 1/2 cup shredded cheese (Gruyère, fontina, or mozzarella all work)
- 1 tbsp fresh thyme leaves (or 1 tsp dried)
- Salt and black pepper to taste
- 1 egg (for egg wash, optional but great for shine)
Let’s Get Cooking! (The Step-by-Step)
Ready? Set your timer. Let’s turn these simple items into a show-stopper. Follow these steps and you can’t go wrong.
- Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
- Slice your mushrooms and spring onions. Separate the white and light green parts of the onions from the dark green tops. We’ll use both.
- Heat 2 tbsp olive oil in a large skillet over medium-high heat. Add the mushrooms. Let them cook without stirring for 5 minutes to get a good sear.
- Add the white/light green parts of the spring onions and the garlic. Cook for another 3-4 minutes until soft and fragrant. Season well with salt, pepper, and thyme. Take off the heat.
- Unfold your puff pastry sheet onto the prepared baking sheet. If it’s not already a rough circle or rectangle, gently roll it out a bit.
- Sprinkle the shredded cheese in the center, leaving a 2-inch border all around. This stops the bottom from getting soggy.
- Pile the mushroom mixture on top of the cheese. Fold the bare pastry edges up and over the filling, pleating as you go.
- Brush the folded pastry edges with an egg wash (1 egg beaten with a splash of water). This gives it that gorgeous golden color. Drizzle the filling with the last tbsp of olive oil.
- Bake for 20-25 minutes, until the pastry is puffed and deeply golden brown.
- Right out of the oven, scatter the reserved dark green spring onion tops over the hot galette. Slice and serve immediately!
What to Serve With This Dish
This galette is a full meal on its own. But if you want to round it out, keep it simple and fast.
A quick arugula salad with lemon vinaigrette is perfect. The peppery greens cut the richness.
For something heartier, try a bowl of tomato soup. It’s a classic combo that always works. If you love mushroom-based meals, a vegetarian mushroom and spinach lasagna soup would be another fantastic, cozy pairing. Roasted asparagus or green beans are also fantastic, easy sides.
Make This Recipe Your Own (Quick Swaps)
Don’t have something? No stress. This recipe is a fantastic template. Play with it!
Swap the mushrooms for sliced zucchini or bell peppers in the summer. Use a yellow onion or leeks if you can’t find spring onions.
Change the cheese. Goat cheese crumbles or feta add a tangy punch. Make it vegan by using dairy-free cheese and skipping the egg wash.
How to Store Leftovers (If You Have Any!)
This galette is best fresh. But leftovers happen.
Let them cool completely. Store in an airtight container in the fridge for up to 2 days.
Reheat in a 350°F oven or toaster oven for about 10 minutes to keep the pastry crisp. The microwave will make it soft.

FREQUENTLY ASKED QUESTIONS
Can I use pie crust instead of puff pastry?
Absolutely! A store-bought pie crust works great. The texture will be more flaky and less puffy, but just as delicious. Blind bake it for 5 minutes first if you want a crisper bottom.
My mushrooms are watery. What did I do wrong?
You probably crowded the pan. Cook them in a single layer over high heat. This lets the water evaporate fast for a good sear. Do it in two batches if your pan is small.
Can I make this ahead of time?
Yes! You can prep the filling a day ahead and keep it in the fridge. Assemble and bake when you’re ready. You can also assemble the whole galette, freeze it on the sheet pan, then bake from frozen, adding 5-10 extra minutes.
See? I told you this was doable. You just made a restaurant-worthy mushroom tart on a random Tuesday. That’s a major win.
