Costco Kirkland Signature Microwave Popcorn tastes almost as good as movie theater popcorn!

Costco Kirkland Signature Microwave Popcorn is something I always see at my Costco and just never picked it up to try and review. This is mainly because my husband is a bit of a popcorn snob. He only likes fresh, hot, movie theater popcorn. I remember when I brought home half my bag of movie theater popcorn he was shocked I’d eat leftover, cold popcorn and was slightly appalled by the concept of farmer’s market kettle corn.

A favorite Costco popcorn product of mine is the Angie’s Boom Chicka Pop Sea Salt Popcorn from Costco. I’ve also reviewed the French Cancan Popcorn from Costco and the Cretors Chicago Mix Popcorn from Costco.

The Costco microwaveable popcorn can be found in the snack section near the beef jerky and granola bars. The item number is 9559.

This is some tasty microwaveable popcorn. The first thing I noticed was how well it popped, there wasn’t many unpopped kernels left in the bag at all. The buttery flavor is super delicious but was a little unevenly distributed. Next time I’ll give my bag a good shake before opening it and pouring it into the bowl.

I love that the buttery flavor doesn’t taste at all fake and overall the flavor of the popcorn reminds me of the popcorn you get when you go to the movies. One bag makes about two heaping cereal bowls full of popcorn.

I paid $13.49 Canadian for the box of 44 bags of popcorn, in my opinion that’s really cheap, 44 bags is a ton of movie nights at home!

This Costco microwaveable popcorn is done in the microwave in just minutes. After heating your popcorn bag in the microwave make sure you open it carefully and away from your face because it’s hot!

This is perfect for a movie night at home, a slumber party or just a get together. We make popcorn at home using the pot method with kernels and it’s definitely not as convenient as microwave popcorn. The best before date on the popcorn is just under a year from the date we purchased it.

Whole grain popcorn is the first ingredient and unfortunately palm oil is the second. I wish there was no palm oil and just natural butter and that’s why I prefer to make my popcorn at home with just butter and a bit of coconut oil.

  1. It would be helpful to note how many cups or quarts the Kirkland Movie Theater popcorn pops out to. What’s the volume of the popped corn?

  2. I bought the microwavable popcorn after trying some at the store. It’s a huge box for one person but I love popcorn and I liked the way they looked at the store; however, I’m very disappointed,,,, they didn’t pop. I opened Two bags and if I got 10 out of each is too much. I had used the popcorn button on my microwave as well as set the other for the 1.45 mins per the instructions. None worked. I’ll be returning them. ,

  3. Why did Cosco changed the bag the popcorn is in the other one was heavier..this one is thin and have to be carefull when opening it.. Love the corn ..thank you

  4. I had long been a fan of Act 2 microwave popcorn but this week bought my first Kirkland 44-pack of microwave popcorn. I am an instant fan. I am 76, I don’t eat popcorn for “health” reasons, when I want a bowl of popcorn I want it to be crisp and tasty, and this Kirkland brand is. One minute and 50 seconds in my 1100 watt microwave. I love it. I just wish I had not waited so long to start enjoying it.

  5. This is probably by far the best value and taste for microwave popcorn you can buy. It’s odd though how popping times can vary between bags. It’s certainly not consistent at all.

    Hot air poppers are terrible and always leave your popcorn dry, dry, and dry. We donated ours many years ago.

    As far as the other poster goes and his fearmongering, he should read the ingredients of this Costco brand before slamming it and promoting his narrative.

    Thank you for your review, Natalie.

  6. After reading that microwaveable popcorn contains, (known Carcinogens/Cancer causing chemicals), I, have since, given it up entirely. I, now, hot air pop, Orville Redenbacher’s Original Popcorn kernels. (Also, sold by Costco, in a huge container, for around $9!) I, then, while still hot, sprinkle it with melted Ghee, (Ghee is East Indian – clarified butter/fat removed), and toss, some Himilayan Pink Sea Salt on it, along with some Kraft Parmesan Cheese, occasionally. (A much healthier choice, overall.)
