How to Heat the Croissants from Costco

The croissants are already fully cooked so you can eat them straight from the tray if desired.  My wife tried one without heating it up and rated it a “7 out of 10” so, definitely edible and pretty dang good.

But trust me, you really want to heat these things up 🙂

Without question, the best way to heat up the croissants is to place them onto a baking sheet and put into a 300F oven for 7-8 minutes.  When the croissants come out of the oven they will be warm, crispy, flaky and buttery.  You will be hard pressed to tell the difference between the reheated croissants and those straight from a bakery oven.

You can set you oven temperature a little higher to 325F if you want but keep a close eye on the croissants to make sure they don’t get too crispy on the bottom.

If you want to dial down the crispiness a little then you can cover the croissants with some aluminum foil before they go into the oven.

I am a huge fan of heating things up in a microwave but please do not abuse these croissants in that manner.  The microwave creates pockets of high heat that absolutely destroys the delicate flaky texture of the croissant.  The croissant will be warm and delicious coming out of the microwave but the crispy, flaky texture will be ruined.

How to Serve Costco Croissants

There is nothing wrong with just tearing into a croissant and devouring it out of your hand.  However, you can also take a minute and serve these things up with some tasty accompaniments!

Serve with a Spread

I love serving the croissants with a side of strawberry preserves.  For me the combination of strawberries with the butter of the croissant is a just about unbeatable combination.  Other spreadable flavors that people love with these croissants include:

  • Nutella
  • Butter + Marmalade
  • Blueberry Jam

Use to Make Sandwiches

Another great way to serve the croissant is to use them to make a sandwich.

Before the croissant gets reheated I like to slice them lengthwise and add some ham, scrambled eggs and Swiss cheese to the middle.  Put the sandwich together and then into a 300F oven for 13-15 minutes until the cheese is melted.

Making a Croissant Breakfast Sandwich

This came out being the best breakfast sandwich that I have ever made.  This sandwich was so simple, yet utterly delicious, that it makes me realize how bad those Jimmy Dean Breakfast Croissants really are.

You could start a breakfast restaurant that sold nothing but versions of these croissants along with a great cup of coffee and it would be an immediate success.

Calories in Costco Croissants

I’ve got bad news and good news when it comes to the calories in the croissants 🙂  The bad news is that a single croissant has the following nutritional information:

  • Calories: 320
  • Fat: 16g
  • Carbohydrates: 36g
  • Protein: 6g

These pastries are made from eggs, butter and flour so you have to be prepared for the calories that come along for the ride.

The good news is that, compared to Costco’s muffins the croissants are super low calorie!  That’s right, you can stroll through the Costco bakery, grab a tray of croissants and get all smug inside because you made the healthy choice and didn’t buy the muffins!

How to Store the Leftover Croissants

You get twelve large croissants per tray and most households will not eat the whole tray in a day.  The croissants should stay good for 3-4 days on the counter but I prefer to keep them in my refrigerator whey they will easily last a week.

You can freeze the croissants but I prefer not to.  To freeze the croissants I wrap them individually with aluminum foil and then place them into a Ziploc freezer bag.  Toss the bag into the freezer and the croissants will keep quite a while….months?

I prefer not to freeze these things because I am short on freeze space.  I don’t want to squish the croissants flat but that is what invariable happens after a week of grabbing other things out of the freezer and pushing the croissants to the side.

How Much do Croissants Cost at Costco

I was able to buy a 12 count of very large croissants at Costco for $5.99.  That works out to a price of just $0.50 per croissant!

Like I mentioned at the start of this post, I think the croissants are one of the most underappreciated items in the entire Costco warehouse.  These pastries are absolutely delicious, rival anything I have ever gotten fresh from a bakery and only cost $0.50 each.

Well done, Costco!
