Preheat the oven for 450°F. Line a small baking sheet with aluminum foil.
Rinse the peppers off and then pat dry with a paper towel. Place the whole peppers on the sheet pan and drizzle avocado oil on the top and bottom. Rub the oil on the whole pepper to coat each one.
Bake for 10 minutes, then using tongs, flip the peppers over. Careful it's hot in there! After another 10 minutes flip again. The peppers should be getting nice and blistered at this point. After that flip again and cook for another 5 minutes. The peppers should be soft and blistered.
Next, take the peppers out of the oven. Using the tongs again place the peppers on a plate and cover with a large bowl. I used a small plate and squished them all on the plate and covered with a large mixing bowl. We want to create a steam room essentially which will help the skins peel right off.
After 25 minutes of letting the peppers steam from their own heat it is time to peel! Be careful as they will still be hot. Feel free to let them cool longer if needed. I chopped the top off of the pepper and then peeled the skin off of each one. I also pulled out the middle with all of the seeds. This should peel very easily. Let the peppers sit and steam longer if the peel is being stubborn.
Once the peppers are peeled, slice or chop them depending on the recipe you are using! Enjoy.
