Ingredients in Roasted Broccoli

With only a few ingredients and five minutes of prep time, this is sure to be one of your new favorite recipes. We love it so much, I make it as a side dish at least once a week!  I hope this recipe will become a weeknight favorite at your house like it is at mine. 

Here are the ingredients you’ll need to make roasted broccoli:

  • Fresh broccoli.  Cut the broccoli into small florets, and rinse well.  Make sure to dry the florets well so that the oil and seasonings will coat them.  Using a salad spinner is a great idea!
  • Fresh garlic.  Mince a few cloves of garlic to flavor the broccoli.  You could also use garlic powder if you are out of fresh garlic.
  • Olive Oil. You’ll need a decent amount of oil to roast the broccoli.  I use 3-4 tablespoons.
  • Salt and Pepper.

Flavor Ideas for Roasted Broccoli

For this basic recipe, I call for garlic, salt, and pepper as the seasonings.  But, you can definitely add more flavors and seasonings to suit your taste.  Here are some ideas.

  • Add a sprinkle of fresh lemon juice over the broccoli once it’s finished roasting.
  • Add up to a tsp of dried herbs, or an all-purpose herb blend.
  • Add a tbsp of balsamic vinegar to the broccoli before roasting.  Add it to the bowl when you’re tossing the florets in the olive oil.
  • Add up to 1/2 cup of grated Parmesan cheese to the broccoli, about halfway through the cooking time. This way it will melt and brown, but not burn in the high heat of the oven.

How to Make Roasted Broccoli in the Oven

Making oven-roasted broccoli is a very simple recipe.  After a few minutes of prep, the oven takes care of the rest of the work for you.

To start, wash and dry the broccoli thoroughly. Cut the broccoli florets into small florets.  Try to keep the size of the pieces relatively uniform so they will cook evenly.

Then, in a large mixing bowl, toss the florets with olive oil, garlic, salt and pepper to taste. Now is the time to add any additional seasonings, like Balsamic vinegar, red pepper flakes, herbs, or other seasonings.

Next, place the broccoli on a large rimmed baking sheet. Spread it out in a single layer, being careful not to overcrowd the pan.

Finally, roast the broccoli in a hot oven for about 20 minutes, or until it is tender and caramelized.  That’s it!

Tips for the Best Roasted Veggies

These tips apply to this broccoli recipe, but also for other roasted vegetable dishes like roasted cauliflower or roasted brussels sprouts.

  • Make sure that the broccoli florets are dry after rinsing them. You can use a salad spinner or pat them down with paper towels.
  • Be generous with the olive oil.  Toss the florets will to make sure that they are coated in a thin layer of oil. The oil will make sure that the broccoli cooks and browns well.
  • Don’t overcrowd the pan.  It’s important to spread the broccoli out into a single layer on a large pan.  You can use two pans if you don’t have one pan that is large enough to hold all of the broccoli.  If you crowd the pan, the broccoli will end up steaming and you won’t get brown and crispy edges.
  • Use a high enough oven temperature.  425F is the sweet spot in my oven.  You may want to buy an oven thermometer if you aren’t sure if your oven is accurate.
  • Shake the pan, or use a spatula to toss the broccoli about halfway through the cooking time for even cooking.
