Wonderbag Portable Slow Cooker with Recipe Cookbook, Blue Batik

What's a Wonderbag?

Wonderbag is a simple but revolutionary non-electric, portable slow cooker. Wonderbag's clever insulation allows food that has been brought to the boil to continue slow cooking or warm while in the bag. No plugs. No Fuss. No electricity required, so it’s worry-free.

Slow Cooking with Wonderbag
Hearty Chipotle Chili
Slow Cooking with Wonderbag

To slow cook, simply bring food to a boil on a stove, let simmer (5 minutes for rice and grains, 15 minutes for root vegetables, meat or presoaked beans), then put the pot with lid into your Wonderbag, close tightly, and slow cook to perfection up to 12 hours. Because it is not on direct heat, it will never overcook or burn. Wonderbag is perfect for bringing delicious home cooked meals to potlucks, dinner parties, tailgating, or camping. It’s perfect for holidays when stove and counter space are at a premium.

Powerless is Powerful - Buy One Donate One

Powerless is powerful. Wonderbag isn’t just a powerless cooker; it’s an instrument for change. 3 billion women still cook over wood fires, a major source of health, environmental and socio-economic issues. By drastically reducing time spent cooking, the Wonderbag empowers women across Africa to participate in more activities outside of the home enhancing their quality of life. Using the Wonderbag helps save water, reduces the carbon footprint, minimizes deforestation, smoke inhalation diseases and deaths. One Wonderbag per year saves 1.7 trees, 1000 liters of water and 1,248 hours of time not spent collecting firewood. For every Wonderbag purchased in the US, one is donated to a family in need in Africa.

Hearty Chipotle Chili

Ingredients: 1 pound ground beef or ground turkey. 1 small onion, chopped. 1 medium red or green bell pepper, chopped. 1 garlic clove, finely chopped. 1/2 teaspoon ground chipotle chili pepper. 1 can (28 ounces) of crushed tomatoes. 1 can (15.5 ounces) black beans, rinsed and drained. 3.5 cups of beef stock. Directions: Cook ground beef, onion, red pepper and garlic in 4-quart saucepan, stirring occasionally, until beef is browned and vegetables are tender. Stir ibeef stock - Beef and chipotle chile pepper until stock is melted. Stir in tomatoes and beans. Bring to a boil over high heat. Reduce heat to low and simmer, stirring occasionally, until heated through. This takes about 15 minutes. Place your lidded pot in the Wonderbag for for a minimum of 1 hours and up to 4 hours for flavors to mingle. Serve, if desired, with shredded cheddar cheese, sour cream and/or chopped cilantro.

Perfectly Fluffy Rice or Grains

Directions: Saute 2 diced onions with oil on medium high heat for 5 minutes in large pot. Add butternut squash, and broth. Boil for 5 minutes. Add thyme. Put lidded pot into Wonderbag for at least 2 hours. Blend. Season with salt and pepper and enjoy!

Best You Know This
  • Use with copper, steel, aluminum, enameled cast iron, or glassware pots in standard sizes with short handles and tight fitting lid. Use the right sized pot for the food you want to cook in order to best retain heat.
  • Bring all food to a boil before putting into a Wonderbag. For best results keep bag and pot closed for the entire cooking time.
  • Hand wash, hang dry. Use a dishtowel in the base of the Wonderbag to protect it from spills.
  • There is no evaporation when cooking, so use less liquid than you otherwise would. If using alcohol in your recipe, allow it to boil off for 5 minutes before placing in Wonderbag.
  • Please note: Wonderbag will arrive vacuum sealed and must be fluffed up before first usage.

Important Information

Safety Warning

To speed cooking time, cut ingredients into smaller pieces. Never put a pot that is over 350 degrees into Wonderbag. If you're unsure of temperature, place a potholder (silicone is best) in the base of the Wonderbag to protect and put Wonderbag on a trivet when in use. Food should not be fall below 135 degrees F for longer than 2 hours before consuming or refrigerating. When in doubt, use a thermometer to ensure you food is above 135 degrees F,


Bring the pot of food to a boil with the lid on long enough to heat the food through. Open the Wonderbag, place a pot holder (we recommend silicone) in the base of the Wonderbag. Place the lidded pot into the Wonderbag and close Wonderbag tightly. Place the Wonderbag on a trivet or a potholder and let pot slow cook to perfection for at least as long as you would otherwise simmer. Open the Wonderbag, season and serve. Enjoy!

This just arrived yesterday and today was only my first use. From what I can tell it does what it is supposed to do, though the instructions might not be completely clear.

"Best you know this" announces the back page of the included booklet, and the "Times" chart suggests that rice and grains need five minutes on the stove and at least 45 minutes in the bag. It would be clearer to understand that it means five minutes on the stove *after* bringing the rice to a boil. Expect at least 10 minutes, possibly more for larger quantities.

I brought a pot of short grain rice to a boil, then simmered for 5 minutes to be sure that the rice was heated through. I opened up the Wonderbag, put a dish towel in the bottom (since the rice had boiled over a bit) and put the pot on top of the towel. Then I covered the pot with another towel, put the Wonderbag lid on the pot, and closed up the bag. I set the timer for an hour.

After an hour I opened the bag (and got a blast of steam) and checked the temperature of the rice. It was over 182°F, definitely hot enough to cook a grain. The rice was cooked perfectly.

The exterior of the bag was cool to the touch, and the countertop under the bag was cool. The interior was very hot, which tells me that the bag insulation is doing a great job of retaining the heat.

Since my pots have long handles, I picked up two pots with short handles and tight fitting lids to use in this bag. A 2 quart pot and a tall 8 quart pot both fit in the bag (individually--not at the same time,) and it's easy to arrange the bag to fit around either pot.

With all this insulation the bag is LARGE. It's going to take up a lot of space when not in use.

I love cooking in my crock pot, and I thought this sounded like an interesting way of cooking, while conserving energy. I've found that it's not quite the same as cooking with a crock pot, even though it is advertised as such.

The food does cook, and it does keep everything hot, but I find that the melding/infusing of flavors that takes place with the crock pot just doesn't happen as well with this approach. Also, I tried following the instructions for making rice in the Wonderbag, and it didn't turn out even though I followed the instructions precisely.

I can see where I might use this to transport hot foods to parties, as the insulation is fabulous, and I may use it with soups, stews, or chilis that are already cooked on the stovetop completely and just need to "simmer" and stay hot until dinner, but I won't be replacing my crock pot or rice cooker with this product.

When my children were younger and I worked full time I relied heavily on a slow cooker to help get meals on the table quick. When I married 25 years ago the best gift I received was a crock-pot slow cooker. I could put ingredients into the cooker, go to work and come back to a delicious meal. We lost that crock-pot many years ago after moving and began a search to find a replacement. Today's "slow" cookers are not what they used to be.

Over the last ten years I have tried many "slow-cookers" and they have changed considerably. Today's modern slow-cookers will come to a boil and can cook your food in as little as two hours on high. After repeatedly coming home to burned and dried out food I stopped cooking with my crock-pots unless I was at home to carefully watch and time the food and even then there was always hot-spots where food would stick, scorch or burn if you didn't stir the food or rotate the stoneware.

Before I decided to purchase a Wonderbag I did my homework and research, read reviews and studied the concept and different designs of thermal cookers or "hay-box" cookers. Why did I decide to purchase the Wonderbag? Most of the recipes I use a slow cooker for require the food to simmer at low heat for longer periods of time. I have several soup and chilli recipes that my now grown children love. All of the ingredients are cooked before going into a slow-cooker and then allowed to simmer so that the flavors infuse and mix together. When I tried the recipes in the newer electric slow-cookers those darned hot spots would burn or scorch if I didn't check it often and stir it. This is not how slow-cooking is supposed to work. Anyone familiar with a slow-cooker knows that removing the lid causes heat loss and increases the cooking time.

I got a wonderbag earlier this year while I was overseas. I work all day and frequently come home too tired at night to cook for myself. The bag alleviates some of the strain for me because I can prepare stuff in the morning and it will be hot and ready when I come home.
I have a few tips to using the wonderbag- use less water in the bag if you want a casserole type dish. There is no evaporation inside the bag.
You must use a tight fitting lid to keep the heat inside the pot- don't open it until you are ready to eat the food, otherwise there is risk for bacteria growth, and heat loss.
I have found the bag to be best used for stews, beans, rice/casseroles, and also yogurt, but I have tried steam baking items inside as well. I know it is used by others to help breads rise and tenderize meat through slow-cooking.
In addition, the bag has other uses to me -thaw frozen goods slowly. The insulation works both ways, and it makes a great picnic basket!

A few comments regarding the materials: I have seen the bag tear if the draw string is not used gently- you need to draw it tight, but don't rip the bag in the process. Make sure you use a good fitting pot for the bag and you won't have this problem. After opening, the bag does not condense down, so it does take up space, I use is as a pillow :) bright cheerful and comfy!

It's cheap, easy to use and easy to make new recipes up for. The food is delicious when slow cooked. Great product!
