What can I do with sprouts and carrots/parsnips tonight

[CarrotPuff]

I've read you can blanch sprouts and store them in plastic bag overnight. Can I do the same with Carrots and parsnips? Can I go further and coat them in oil and honey ready to shove in the oven tomorrow?
Thanks!

Following as I'd love to know too. Two under two and worried about being stuck in the kitchen

I have cut my parsnips and carrots up and they're in the roasting tin in the fridge ready to go straight in the oven. Don't see why you can't do the same with sprouts but I don't like them!

Well I've prepped them and put into trays ready for tomorrow! 🤞🏻 they turn out OK!
