For the roasted garlic guacamole
Cut off the top third of the head of garlic, exposing the tops of the cloves, and drizzle with oil. Wrap in foil and place garlic in the basket of the air fryer. Cook at 400F for 20 to 25 minutes until the cloves are soft. Remove the garlic from the air fryer, unwrap, and allow to cool. Squeeze the garlic cloves into a large bowl.
Place the jalapeño pepper in the basket of the air fryer and cook at 400F until the skin is blackened on all sides, turning 2 or 3 times, approximately 12 minutes. Remove the pepper and cover for 10 minutes. When the pepper is cool enough to handle, remove the charred outer skin. Remove the seeds and dice the pepper. Add to the bowl with the roasted garlic.
