How To Serve
These taste amazing when they're just a bit warm the cheese stays all melty and gooey! I like putting out some extra French onion dip on the side for dunking everyone loves that. They go great with party snacks, but truth be told? Sometimes we just have a batch with a green salad and call it dinner!
Storage Tips
They taste best right after baking, but if you somehow have extras (rare in my house!), just stick them in the fridge. Warm them back up in your oven to crisp them again don't use the microwave unless you want soggy results! Here's a time-saving trick: you can make the whole roll ahead and keep it cold, then just cut and bake when company arrives.

Frequently Asked Questions
- → Can I make these ahead of time?
- You can get everything ready and cut the spirals beforehand, then pop them in the fridge until baking time. Just add the egg wash right before they go in the oven. They taste best when they're fresh and warm.
- → Why let puff pastry thaw?
- Soft, thawed pastry won't crack when you roll it. Frozen pastry will break and won't roll properly. Let it sit out for about 40 minutes and you'll be good to go.
- → How do I prevent the pinwheels from unrolling?
- Brush the edge with egg wash so it sticks well, and always put the seam side down when cutting. If your pastry gets too warm and soft, stick it in the fridge for a few minutes first.
- → Can I use different meats or cheeses?
- For sure! Try it with turkey, ham, or other sliced meats. Any cheese that melts works great too – give Swiss, cheddar, or mozzarella a try.
- → Why brush with egg wash?
- The egg wash helps the pastry edges stick together and gives you that pretty golden shine when baked. It also makes toppings stick better to your pastry.
