Please tell me about multicookers....

[Ireallyshouldchangemyusername]

Hi all
Some good black Friday deals on and think that if in going to splurge on an airfryer/pressure cooker/multicookers thing then i will plump for the instant pot brand rathee than ninja as pricing is more competitive and I like the idea of stainless steel pans better. I do have a few questions (very basic ones) if people could help.

First, there is a good price on the instapot duo with the separate af lid.. Particularly the 8l one. We are a family (at the moment) of 3 but batch cook loads and love having a well stocked freezer and use our large stock pot loads on the hob. Would 8l be too big? Can it be too big?

Second how does it work making a meal in the one pot using all the functions, like how do I roast a chicken and cook my potatoes and steam veg at the same time? Or is that only possible with an airfryer with 2 baskets (but then how do you steam in one of these contraptions?)

I am very confused but would like a pressure cooker and slow cooker functionality so think the instant pot is the way forward.

Am open to any and all suggestions and advice. Although it doesn't sound like it, I am quite a competent cook. This is just making me nervous.. Especially with a very skeptical husband.

TIA

Oh and sorry for the slew of typos.. In my phone with fatnfingers!

Instant pot has two lids depending on function used. Then stainless steel bowl and an airfryer basket. You can only use one setting at a time. Eg you can't airfry and slow cook at the same time

Thanks, so at risk of sounding really stupid, could i do a roast chicken with roast potatoes and steamed broccoli all in one go? I see these beautifully plated meals and just think How? Is it all too good to be true?
