Make microwave popcorn in a brown paper bag!
I stopped buying the store-bought microwave popcorn bags a while ago. The ingredient labels are a little much, and once I realized making microwave popcorn in a paper bag is just as fast, there was really no reason to go back. I toss the kernels in a little oil and salt, fold the bag, and the microwave does the rest. Three ingredients. Two minutes. Done.
My kids ask if they can make microwave popcorn constantly, and I love that I can say yes without thinking twice about it, using this method. This brown bag popcorn is easy to customize after it comes out, melted butter, cinnamon sugar, everything bagel seasoning, whatever we’re feeling, but most of the time I just hit add a little extra flaky salt and eat it straight from the bag. Soo good!
Happy Cooking!

Microwave Popcorn in a Bag Ingredients
- Popcorn kernels: ½ cup is the right amount for a standard lunch-size brown paper bag. You don’t want to try to add more, or it won’t work right, and you’ll end up with a mess. Plain, unflavored kernels from any brand work. Look for popcorn kernels near the boxed microwave popcorn at the grocery store. Make sure they’re fresh!
- Avocado oil: Any neutral oil works. You can also use melted butter. Measure carefully, because too much oil can make the popcorn greasy, but too little can cause it to burn more quickly.
- Salt: You’ll add salt to the kernels before microwaving them, then more to taste before serving.

Notes
Nutrition
Nutrition information provided is an estimate. It will vary based on cooking method and specific ingredients used.
Recipe Variations
- Savory popcorn: Try 1 teaspoon of ranch seasoning, 2 tablespoons of nutritional yeast, or combos like 2 tablespoons Parmesan with ¼ teaspoon black pepper, or ½ teaspoon each of garlic powder and onion powder.
- Sweet popcorn: I love adding 1 tablespoon cinnamon sugar (1 tablespoon sugar + ½ teaspoon cinnamon), a drizzle of 2 tablespoons melted chocolate, or ½ teaspoon pumpkin spice with 1 tablespoon brown sugar.
- Mix-ins: Toss the popcorn with ¼ cup roasted nuts, ½ cup pretzels, 2 tablespoons mini chocolate chips, M&Ms, or dried cranberries, or ½ cup of your favorite cereal.
Recipe Tips
- Let the bag sit for a few seconds before opening. The bag will be hot! Open it carefully so you don’t get blasted with steam. But don’t wait too long to open it, otherwise the popcorn may steam too much and get chewy.
- Add seasonings after popping. Since you toss the kernels with oil and salt before microwaving, I recommend adding any seasonings to the popcorn after it pops, while it’s still warm. You may need to drizzle the popcorn with a little more avocado oil or melted butter to help the seasonings stick.
- Use sound, not the timer. Every microwave runs differently, so 2½ minutes in one kitchen is 2 minutes in another. Start listening around the 90-second mark and stop as soon as the pops slow down. Letting it go too long is the main reason popcorn burns.
- Fold the bag well. Two or three tight folds keep the bag closed while it pops. A loose fold can come open in the microwave and make a mess.
FAQs
You likely microwaved the bag for too long. Make sure you take it out when the popping slows to about 2 seconds between pops.
You may have stopped the microwave too early. Or, your popcorn kernels may not be fresh anymore.
You can, but I still recommend staying close by and stopping the microwave when the pops are 2 seconds apart. Relying on the popcorn button alone often leads to burnt or unpopped popcorn, because it doesn’t know how much you’re making. Some newer smart microwaves have sensors that can detect when the pops are far enough apart, but you can’t go wrong with the 2-second method!
I recommend a standard small microwave-safe lunch sack with no printing or ink on it. Make sure it’s uncoated, plain paper, not waxed or glossy.
