Make Your Own Potato Bag for the Microwave

Potato bags that go in the microwave are the key to making your potatoes taste like they came from a restaurant and you can use the bags for rolls, tortillas and more.

Here’s another interesting project from our friends and sponsors at The Warm Company that I can’t wait to try mainly because I LOVE baked potatoes or should I say, “Warm Taters”!

Potato Bag Instructions


Potato bags are all the rage and The Warm Company has the right batting for all your microwave and kitchen projects! Warm Tater is 100% natural cotton that hasn’t been chemically treated making it ideal for cooking potatoes, corn, rolls and warming tortillas in the microwave. Warm Tater is heavy weight 100% natural cotton that acts as an insulator keeping the moisture inside for fresh, hot steamy potatoes & so much more! This quick, simple & practical project makes a great gift item! Amaze your friends and treat yourself!

Materials List:

Warm Tater and your cotton fabrics do not need to be pre-washed.  Once the potato bag is complete you will wash then all together.

Measure the inside dimensions of your microwave and adjust the pattern accordingly considering that the finished bag must be at last one full inch away from the walls and door of the microwave.  CAUTION:  If your microwave has a turntable, it is important that your potato bag be allowed to freely rotate or scorching may occur that could lead to fire if left unattended.


1. Cut a 22” long by 11” wide piece of Warm Tater cotton and two pieces of 100% cotton fabric.  One is the lining and the other is decorator fabric.

Thread Tip:
It’s best to use Coats Cotton all purpose thread because polyester thread has a melting point which, might be a problem.  So, to be on the safe side, the cotton would be a better choice.

2. Layer the Warm Tater cotton between the two layers of fabric right sides out.  Quilt or tack layers together leaving no more than 5” open.

3. Surge or sew the three layers together on all sides using a zigzag stitch.

4. Create finished hems on each of the width ends by folding the fabric to the inside a ½” and sewing it down using a straight stitch.

5. Fold the fabrics into a 10” square (or appropriate size for your microwave) inside out with hems centered and overlapping 1”.  Pin and sew all sides with a straight stitch and ½” seam allowance.

6. Turn right side out.  Machine wash cold water and dry in warm dryer before use.  Enjoy!

Cooking Instructions:
Potatoes – 2 large = 8 minutes
Red Potatoes – 2 large = 8 minutes
Sweet Potatoes – 2 medium = 10 minutes
Rolls – 3 medium = 20 seconds
Tortillas – 1 package = 30 seconds
Corn on the cob – 2 large = 6 minutes

The above estimates are based on an 1100 watt microwave with turntable.  No turntable? Turn your bag over at the midpoint of the suggested cook time to prevent scorching.  Wash vegetables.  Drying is not necessary as the moisture aids in cooking.

And we all know, NEVER LEAVE YOUR MICROWAVE UNATTENDED WHEN ITS IN USE! This sounds very familiar to Matt and I, it’s just like the old line we had to say about 1,000 times on HGTV, “And remember, never leave a burning candle unattended.”  Of course it’s important information, I just repeat it I in my sleep now….that and dream of Warm Taters!!!

      Doris, I am looking into your question. I’ve even been on the Warm Company website and I don’t see it listed anymore…perhaps it wasn’t a big seller? I’ll let you know when I get an answer from them! – Shari

    I found 100 Cotton batting at Hancock Fabrics. It is the their own brand called “Sew Perfect”. It has no scrim, no poly………perfect for Potato Bags

      Evie, thank you so much for your help. I left a message at The Warm Company and I haven’t heard back from them. I really appreciate your help!

        From their website:
        “Unfortunately, we had to discontinue manufacturing the Warm Tater batting. We did make a similar product to replace Warm Tater. Our new Warm & Plush is made the same way as Warm Tater with a few improved changes –”
