ステーキ（玉ねぎステーキ）｜馬場ごはん〈ロバート〉Baba's Kitchenさんのレシピ書き起こし

Before washing the onion with the skin on, rub the dirt off the root with your fingers and wash it under running water.
Cut the onion in half lengthwise, leaving the root intact.
Cut off the tip of the onion and peel off the skin.
Place the onion on a heat-resistant plate and cover with plastic wrap.
Microwave at 600W for 4 minutes.
Add the ponzu sauce to the grated garlic in a bowl and mix to make the sauce.

Put the butter in a frying pan and heat it to melt.
Place the onion cut side down and heat over medium-low heat for 1 minute.
Cover with a lid and simmer for 1 minute on low heat.
Remove the lid and when the cross section of the onion is browned, turn it over.
Bake for 2-3 minutes, then add the sauce mixed in step 1, cover with a lid, and cook over high heat for 1 minute.
Remove the lid and let the sourness evaporate.
Remove the onions and bring the sauce to a boil.

Transfer the onions to a plate and pour the sauce over the top.
Add cherry tomatoes and parsley if you like, and finally sprinkle black pepper to complete.
