To par-boil or not to par-boil root vegetables before roasting?
I'm looking at some recipes for roasted root vegetables and there appears to be a split between those that par boil then roast for ~30 minutes versus those that just roast for ~45 minutes
Excluding potatoes - where there appears to be a consensus that par boiling is necessary, what are the pros and cons of each approach? and is it more important for particular types of root veg?
Best Answer
I think this depends on how big the pieces are, and of course which ingredients. Some veg cook faster than others.
If you are using 1 inch or smaller pieces, you may not need to parboil, but if you are using larger pieces you may wish to par boil for longer as the pieces get bigger.
This lets you cook the interior without burning the exterior when you roast.
Of course if you add things like squash or broccoli to the veg roast, add those last and they don't need par boiling.

Answer 2
Parboil if you like your moist (boiled) veg to have a bit of color and chewiness.
No parboil if you like veg flavor concentrated and texture to be more leathery.
Answer 3
Parboil potatoes, carrots, turnips and celeriac and the like because they are very dense. Don't parboil onions or other less dense roots.
Answer 4
Parboil is faster and useful if you can't vary the heat of your oven e.g roasting a bird. However I find cooking root veg whole at a lower heat for longer keeps root veg moist inside. Carrots and parsnips at 160 Cecius/140 fan for 1.5 hours.
I tend to cook my carrots Vichy style. Put single layer in pan with butter, a wee but of sugar and maybe some star anise which is lovely. Once they are soft you can fish out and pan fry briefly for a crispy coating. The real bonus is that adding a little stock to the carrot cooking juice and reducing gives you a magnificent sauce with the added bonus of carrot vitamins and minerals which may be lost to the water when parboiling.
