Perfect Roasted Vegetables

Before going Paleo, I had a very small number of veggies in my regular rotation – green beans, salads… and I think I was counting corn as a vegetable at the time, too (fun fact – it’s actually a grain and falls more into the starch category!). Even though my Mom cooked from scratch nearly every night growing up, no one in the family was really a big veggie lover, so we just kept our sides simple. But, once I cut out grains I realized I really needed to up my veggie game. Not just for health, but for the sake of variety! A person can only eat so many green beans, after all.

So, after many years of not really eating broccoli, cauliflower, brussels sprouts, asparagus, etc, I decided to start trying a new veggie every week. I quickly found that the key to making them taste good was roasting! There didn’t seem to be any vegetable that didn’t get better with roasting. Soon enough, I was happily eating big servings of veggies and actually starting to crave them.

When it comes to roasting vegetables, you can roast almost any vegetable in the oven with good results! The only thing I typically stay away from is leafy greens. There are three different categories of vegetables to consider when roasting:

  • Root vegetables and winter squash – potatoes, sweet potatoes, carrots, turnips, rutabaga, butternut squash, acorn squash
  • Cruciferous + medium-weight vegetables – broccoli, cauliflower, brussels sprouts, cabbage, bell peppers, onions
  • Tender vegetables – zucchini, summer squash, asparagus, snow peas

High heat at 400°F is best for roasting vegetables. We’ve found that this temperature results in roasted veggies that are perfectly crispy on the outside and nice and soft on the inside.

How Long to Roast Vegetables

  • Potatoes – 35-45 minutes
  • Sweet Potatoes – 35-45 minutes
  • Carrots – 35-45 minutes
  • Turnips – 35-45 minutes
  • Rutabaga – 35-45 minutes
  • Butternut Squash – 35-45 minutes
  • Acorn Squash – 35-45 minutes
  • Broccoli – 25-35 minutes
  • Cauliflower – 25-35 minutes
  • Brussels Sprouts – 25-35 minutes
  • Cabbage – 25-35 minutes
  • Bell Peppers – 25-35 minutes
  • Onions – 25-35 minutes
  • Zucchini – 15-25 minutes
  • Summer Squash – 15-25 minutes
  • Asparagus – 15-25 minutes
  • Snow Peas – 15-25 minutes

Yes! If you want to roast root vegetables at the same time as cruciferous vegetables, for example, we’d recommend giving the root veggies a 10 minute head start in the oven, then adding the rest of the veggies to the tray to continue to roast. You can also get around this by doing what we did in the recipe below and cutting the root veggies into smaller pieces so that they roast more quickly!

How to Make the Best Roasted Vegetables

Knowing how long to roast your vegetables and what temperature to roast them at is half the battle, but here are a few other tips for perfect veggies:

  • Use good oil. This is a place where you don’t want to skimp on oil, because you’ll wind up with dry veggies, but you also don’t want to go overboard and wind up with greasy, soggy vegetables. I use around 2 teaspoons to 1 tablespoon per pound of vegetables. I like to use a good-quality olive oil like this one for added flavor, or you can go with a lighter-tasting avocado oil like this one.
  • Use a nonstick pan. Here we’ve used these non-stick stainless steel pans, but you can also line a pan with parchment paper. This prevents the vegetables from sticking so you don’t lose the crispy parts when you take them off of the pan.
  • Don’t crowd the pan. Make sure your vegetables have plenty of room on the pan. If you have them overlapping they will begin to steam and won’t crisp up the same way they will when given plenty of room!
  • Make sure you season them well. Salt and pepper go a long way to making yummy roasted vegetables, but additional herbs, spices, garlic, and a squeeze of lemon at the end can really take your veggies to the next level. You can even do a fun twist like this buffalo roasted broccoli or these garam masala roasted carrots!
  • Keep a close eye on the veggies as they cook. Set your timer for the lower expected roasting time, then keep a close eye on the veggies after it goes off – they can quickly turn from not done to burnt!

    Do you worry about roasting at high temps with olive oil? I have ready so much conflicting information on this and that you need to cook at low temps with olive oil due to the smoke point.

      I haven’t found a veggie that doesn’t taste good roasted. Even radishes and cucumbers.
      One dish that I make often is zucchini, red onion and tomato. E.v olive oil. Sea salt, pepper, some garlic and onion powder. So good.
