Question: Do you use oil to cook with?
Document: However, do not follow their instructions to only use three sprays of cooking oil. Simply use olive oil and coat the fries lightly. As well, cook them about 25 minutes, not 15 as described and turn them halfway through. Not as messy as deep-frying them, but a little bit of a hassle and the mesh basket really has room for only enough fries for two people.
The little sprayer did not work for spraying oil - either it does not have a pump or we could not figure out how to work it. We already have an oil spritzer so we'll use the little bottle for spraying mold spores on cheese or water on the trombone slide or something.We also made some purslane in it - spritz it with a tiny amt of oil, sprinkle with salt, and cook until crisp at 325. You can eat it stems and all.
One word about fries, though. I don't know why they always show them on the front of the box of these oil-less fryers because I have yet to find one that produces crisp fries. The ones it does cook taste fine, more like real potatoes than fried ones, but never, ever crisp, no matter what I do to them beforehand. Has its uses, but sometimes I still use the old frying pan.
I just got this Oil-less Fryer and I just LOVE it! I couldn't wait to learn how to use it. It is ideal for skinless chicken, which I buy lots of and it is such a breeze to cook with this fryer! It gives you time and temperature for cooking; you also get a bonus recipe book. When I say I love this fryer, I am in dead earnest!My chicken came out just right. It had a nice and crisp exterior and a perfectly moist interior.
I wouldn't say this is an answer to cooking without oil and will probably use more for not heating the kitchen during our long hot summers. Don't feel it lives up to their advertisements.
I was looking forward to the Boss Oil-Less Fryer for a number of reasons...I was expecting something easy to use and healthier for me than fried foods.
Finally got a chance to try out this new oil-less fryer. I have to admit, that at first, it seems rather unbelievable that a gadget like this can do some very good fried foods. I have to say that you have to read the instructional manual, it would help with the use of the machine.
However, my second batch on the high rack turned out even worse. They were cooked through, but did not brown at all. The onion rings didn't fare any better. They were slightly crisp, but not browned. I suspect that the manufacturer knows this and has included a spray bottle that you can use to spray oil on the food if desired.
First off, you will NOT get the same results as from a real, good quality deep fryer. I didn't expect too. But I was surprised by how much I liked this fryer. First off, I love that you use no oil. First off it's obviously healthier but also saves you money since you're not using up so much oil.
The Big Boss Oil Less fryer is easy enough to use, but there's a learning curve involved with it. Cooking with the Big Boss is a little different than cooking with other appliances and it requires a general knowledge of how to get good results.So, be prepared to spend some time looking over the instructions and recipe booklet included in the package.
Answer: Often I use no oil at all and food comes out great!  For homemade french fries, sweet potato fries, etc. I usually just spray a fine mist of oil using the included mister bottle.  Olive oil works good as I'm sure other healthy oils would as well to add to the crispness.  I do weight  watchers and the small amount of oil I use for the frying aspect is not a significant source of calories.
