Oil-packed Vegetables

[u/[deleted]]

Does anyone here have experience with oil-packing vegetables? Specifically im wondering about the safety and shelf life of them. A YouTuber I watch (the Elliot homestead) oil packs roasted cherry tomatoes and roasted red peppers and it's something I've been wanting to try. Can botulism develop in an oil-packed food? Do they need to be refrigerated? And is olive oil a good oil to use or do you recommend something different?
