I would try it, a youtube research chef did a video regarding deep frying at home.
Your better off deep frying then for a short time till crisp then putting in the oven on a wire rack for further cooking. Her way has a few flaws but if you really wanna do it here are a few tips.
TL;DR: get a deep fat fryer at home.
Make sure everything is seasoned breaded and ready to go when doing this. This is a very quick movement, no time for thinking about other things when doing this. Make sure your tongs, oven mitts whatever is ready to go so you’re not looking for shyt when it’s go time. You are dealing with hot oil, no time for distractions or fukking around.
1. Heat the oil in the oven first on the top shelf. This process has to be done on the top because
heat rises and that will be the hottest part of the oven.
This moment is go time
2. Then put the oven tray with the hot oil on the stovetop and turn the burners on under your tray.
That way the heat stays in the oven and keeps the oven at a consistent temperature. The oil into your oven tray/pan also stays hot while adding your chicken and the oven is back up to temperature when you put your chicken back in. She was putting the chicken in with the oven door open and losing all the heat. Rookie mistake big mama.
3.
Space your chicken evenly. Do not over crowd that pan. Don’t let that meat touch each other they will stick together. Steam up in the pan, release all the juices and ruin the whole pan and becoming a soggy floppy mess.
Note: your oven tray has to be a thick one for this to work properly. The thin oven trays warp very easily with heat and also over heats really quickly on the stove top . DO NOT USE A DISPOSABLE TRAY.
4. Get yourself a meat thermometer. They are really cheap and take the guess work out of cooking. That way you can test the temp on your chicken by poking the thickest part of the meat on one or two pieces and know your done.
5. Know your ovens hot and cold spots. For example my oven had a hot spot at the back so put the breasts at the front, thighs and legs at the back.
6. When turning your chicken take it out of the oven and do it on the stove top, keep the oven temp consistent. The colder the oil the more it gets sucked into the chicken. Turn those burners on medium high or so and flip. Work quickly and put it back in the oven.
7. Use tongs. It’s quicker to grip and flip than poking with a fork and letting the juices run out.
8. Once the chicken in browned to the colour you want, take it out the oil and transfer to a wire rack in another oven tray to keep cooking on the middle or top shelf dripping out the oil into the pan and crisping up.
9. I don’t know her flour mix but I would add 1tbsp or so of baking POWDER and 1tsp or so of baking SODA to the mix to help with crisping, substitute a cup of flour for a cup of cornstarch to lighten up the flour mix and may be 1/4 cup potato flour if you got it. This will ensure your coating is light and crispy.
All the methods above are to ensure the chicken stays crispy, the heat stays consistent for the most efficient cook time and to allow you the best of both worlds.
It’s easier to get a deep fat fryer trust me. I have two; and once you start doing it at home there is no going back.
