Can you share the make and model of your slow cooker? It might generate some interesting discussions. If anyone else uses this "one trick" (joke), please post your make and model here.
I've used this in the past with my instant pot, though it's been a while and I don't recall the exact recipe. I've actually taken to par-cooking my onions sous vide, draining them, and then caramelizing them on high heat on the stove.
I have used 4 different makes and models, from a really old one on my grandma’s kitchen that only had a on/off switch, to my newest one, a programable hamilton beach. I would say everyone worked the same, at least for beans, rice and some stews.
I only did caramelized onions twice with the same one, but based on my experience, any brand/model should work. And I agree, crockpot is the best way to cook caramelized onions.
I bought it over a decade ago, and have since left it behind when I moved to Europe. It was a Hamilton Beach brand but don't ask me what model. It had a shutoff timer, which was nice because I could set it to cook a roast while I was at work, and not have to worry about what time I got home (it would stay on "keep warm" after cooking).
