Between you and me, I used to think that broccoli was…boring. Not bad, definitely good for you, but not something I ever found myself thinking about until I needed a last-minute vegetable side dish. Then I’d plop a bunch of broccoli in a steamer and be done with it. Vegetables, check.

That all changed when I started high-temperature oven roasting vegetables. The high heat from the oven is perfect for cooking broccoli. It caramelizes the natural sugars in everything, making cruciferous vegetables like cauliflower, Brussels sprouts, and broccoli sweet, nutty, and downright edible. Devour-able, even.

Even though I always make way more than I think I’ll eat, it’s always gone by the time dinner is over.

Tips for the best Roasted Broccoli (and any other vegetable) you’ll ever have:

Once you have the basics down when you're learning how to roast vegetables, you probably won't need a recipe anymore-it's that easy!

  • Keep the temperature high: Roasted vegetables enjoy higher oven temperatures to develop caramelization and a deep, rich, concentrated flavor. I like to roast every vegetable at 400 degrees (it's easy to remember and my parchment doesn't burn) and just adjust the baking time.
  • Uniform sizes: No matter what vegetable you’re roasting, make sure that everything is cut in the same general size, for even cooking. Slicing increases flat surface area, too— the flat surfaces make more contact with the baking sheet, which is good for flavor.
  • Keep things dry: After you wash your vegetables, pat them dry or allow them to air dry before they go into the oven. More moisture= more steam, which prevents things from getting toasty and crisp.
  • Roast like with like: If you’re just roasting one type of vegetable, you don’t need to worry so much about this... But if you're mixing it up, see the section below for how I like to sort my vegetables for roasting.
  • A little oil goes a long way: You don’t need a ton of oil to roast vegetables. Drizzle a thin stream of olive oil over the sheet tray, and gently toss with your hands to coat everything. Or use a spray mister with your favorite cooking oil to lightly coat your vegetables. If you like, you can combine oil and vegetables in a bowl and toss them before arranging them on the baking sheet.
  • Don't crowd your veg: Crowded vegetables create steam, which prevents them from getting roasty. The baking sheet surface in contact with the broccoli is what gives your roasted vegetables those brown, crunchy bits. Also, flip your veggies halfway through cooking so the other side has a chance to get just as delicious.

What parts of broccoli can be roasted?

These days, I’m big on using everything I buy with little waste, especially food. If I purchase a whole head of broccoli, chances are I’ll be using almost every last bit of it to roast. Sure, I’ll trim the dry part of the stem at the very end, but the rest of the head and stem is fair game for roasting.

If the stem still looks green and tender, not woody, you can roast broccoli stems along with the florets. Stems provide great texture and give you more bang for your buck, too.

With a sharp paring knife, I cut vertically through the stem to make long slices that include both floret and stem.

Can you roast frozen broccoli?

Yes, you can oven roast frozen broccoli florets, right out of the bag. I prefer roasting frozen broccoli at a higher temperature, though— 450 degrees, and cooking the florets straight from the freezer into the oven.

Don’t let the broccoli thaw out first, otherwise it’ll turn soft and won’t ever get crispy.

Flavors and Toppings for roasted vegetables:

Salt and pepper go a long way, of course, and so do lemon juice and Parmesan cheese. But here are some other fun ways to add flavor to roasted vegetables:

  • Lemon, lime, or orange zest: Add citrus zest grated over roasted vegetables before serving.
  • Bacon: Toss a couple slices of bacon, cut up into chunks, in with the mix.
  • Nuts and seeds: Toasted pecans, walnuts, almonds, hazelnuts, and more provide a great crunch on your veggies.
  • Dukkah: My go-to nut and see blend that you can keep on hand for extra flavor any time.
  • Balsamic vinegar: A drizzle of your favorite balsamic vinegar introduces a nice acidic punch to veggies.
  • Use a mustard glaze or a chili oil to brush over the top of the vegetables as they roast.
  • Sauce: Hollandaise, teriyaki, lemon butter - they're all good! Cheese sauce is another winner.
  • Dried fruits like cranberries or raisins (see my Harvest Roasted Vegetables for inspiration)
  • Make your own mayo: a good-quality mayonnaise, or one you make your own, is a fabulous dip for roasted veggies of any kind.
  • Cheese: Parmesan, grated Asiago, pecorino, or Romano cheese are all delicious.
  • Coconut aminos or soy sauce can be drizzled over vegetables instead of salt.
  • A Lemon Vinaigrette or other sauce can be a nice change.

Do different vegetables have different cooking times?

When you’re planning to roast combinations of vegetables, such as roasted broccoli and potatoes, you need to know that  vegetables have different densities, and therefore slightly different cooking times.

Vegetables that take longer to roast can be put in the oven beforehand, and then shorter-cooking vegetables can be added to the tray partway through the roast.

Not all of this is a hard and fast rule, however. If you want to roast broccoli with garlic, for example, you can definitely can. Just add slices of garlic to a sheet tray of broccoli without worrying about keeping them separate.

Vegetables that take longer to roast:

These vegetables take 30-60 minutes, depending on the size of the slice/chunk/or  left whole.

  • Squash: kabocha, pumpkin, butternut, acorn, delicata, spaghetti squash
  • Potatoes, root vegetables, and tubers: Beets, carrots, sweet potatoes, potatoes, parsnips, turnips, rutabagas
  • Alliums: Garlic, shallots, onions, leeks
  • Tomatoes

Vegetables that have a shorter cook time:

These vegetables take 18-25 minutes depending on the slice/chunk/or left whole.

  • Brassicas: broccoli, Brussels sprouts, and cauliflower
  • Mushrooms: shiitake, morels, cremini, portobello, and hen of the woods
  • Summer squash: zucchini, pattypan, and yellow squashes
  • Peppers: bell peppers, poblano, and Hungarian peppers
  • Asparagus
  • Green Beans

Do you need parchment for roasting vegetables?

No, you don't, but it makes cleanup easier and I just love it.

But always remember the Farenheit 451 rule: Books burn at 451 degrees, and so does parchment paper.

That's why I chose 400 degrees as my baseline, even though some vegetables could be done quicker at a higher temp. I sacrifice the occasional vegetable efficiency for the formula.

So many vegetables to roast, so little time:
