ingredient notes & substitutions

Find the full ingredient measurements and instructions in the recipe card below!

ingredients needed to make spinach croissants in bowls with labels.

Croissants: Costco is the best place to get croissants from, especially if you plan on doubling the recipe to feed a crowd! Try and pick a box that looks lightly golden so that they have time to be baked before getting too dark.

Frozen spinach: Frozen spinach is quick and easy to find! If you prefer to use fresh spinach, cook it first, then let it cool before using.

Mozzarella cheese: Do not use pre-shredded cheese or it will not melt properly in the oven. Buy a block of cheese and shred it yourself for the best results. You can also use a mix of half mozzarella and half parmesan cheese.

Cream cheese: Make sure it is softened before using or there will be chunks of cream cheese in the filling.

how to make spinach-filled croissants

Before you start, line a baking sheet with parchment paper and preheat the oven to 375 F.

STEP ONE: Make the cheesy spinach filling. In a large bowl, combine the spinach, shredded mozzarella cheese, mayonnaise, cream cheese, garlic powder, onion powder, salt, and black pepper.

STEP TWO: Cut the croissants. Use a serrated knife to slice open the croissants almost fully open but not all the way! Just enough to stuff them. Place them on the prepared baking sheet.

STEP THREE: Stuff the croissants. Distribute the filling among all eight croissants. Use a spatula to spread the filling evenly across the croissant.

STEP FOUR: Top with seasoning & bake! Use a pastry brush to brush the honey on top of the croissants. Then sprinkle with Everything Bagel Seasoning. Bake in the preheated oven for 8-12 minutes, or until the tops are a deep golden brown and the cheese filling is hot and melty. Serve immediately!

expert baking tips

  • Use a kitchen scale. Baking with a scale is much more accurate than cup measurements. To convert this recipe, click the “metric” button next to the ingredients title on the recipe card. If you do not have a scale, use a spoon to fluff the flour first, then spoon it into your measuring cup.
  • Make it for breakfast. Fry up a few large eggs and add them to the croissants after baking!
  • Use all butter croissants for the best flavor. Some store-bought croissants don’t use butter or only half, I highly recommend not using them. They don’t have that bakery flavor and with few ingredients, you definitely taste the difference.

storage & reheating

Because the filling contains cream cheese and mayo, I recommend storing any leftovers in an airtight container in the fridge. They will stay fresh for 1-2 days.

Although they are best served the day of, you can easily reheat the leftovers. Place them on an unlined sheet pan and heat them in a 350 F oven for 5-6 minutes or until warmed through.

faqs

Can spinach croissants be refrigerated?

Yes! In fact, I highly recommend storing them in the fridge because of the filling.

Can I use gluten-free croissants?

Definitely! Any kind of croissant will work.

Can I use a different kind of cheese?

To make them extra cheesy, I recommend leaving in at least half of the mozzarella. For the other half, try feta cheese, parmesan cheese, or a combination of all three!

What kind of croissants do you recommend for this recipe?

I tested a lot of storebought croissants and the best ones were from Costco. Their croissants are made with all butter so they have the best flavor and taste just as good as the ones I used to make in bakeries!
