Wash the whole peppers thoroughly under cold running water.
Then, clean them from the seeds. The most effective method is to divide the pepper lengthwise into 4 parts and hollow out the seeds (similarly to how my grandmother peeled apples for apple pie)
Peel and cut the red onion in the same way
In the second step, place the pepper quarters in single layer on a baking sheet lined with parchment paper and place the garlic and onion between them (this will make the roasted peppers have a stronger aroma)
Drizzle with olive oil and place in a preheated oven at 180 degrees C (375 degrees F). Depending on the oven, bake for about 30-45 minutes.
After roasting, the peppers will have blackened skins, sometimes charred skins that will quickly come off the pulp.
The Air Fryer will significantly shorten the baking time of red peppers to about 15-20 minutes at 160 degrees 320 degrees F (however if you want a larger quantity, the oven will be better. Half the portion fits in my already large air fryer. I prefer the oven method because I can roast many peppers, and this dish sells like hotcakes at my place.
