It’s great served along with pretty much any dinner and it’s ready in less than half an hour. Read on to learn why you should be making this delicious roasted vegetable tonight!

Why Roast Frozen Broccoli?

A bag of frozen broccoli is usually less expensive than buying a bunch of fresh florets. Another  bonus is that it’s already been washed, chopped, and blanched, so it should take less time to cook than fresh broccoli because the prep work has been taken care of for you. Roasting frozen broccoli will not yield exactly the same result as when you make fresh roasted broccoli, but it’s pretty close. 

How to Roast Frozen Broccoli

Preheat the oven to 450ºF. Line a baking sheet with parchment paper and place in the oven while it heats. In a bowl, drizzle 2 tablespoons of olive oil over the florets and sprinkle with salt or seasonings of choice. Try your own or one of these:

  • Soy sauce
  • Lemon juice
  • Garlic powder
  • Chili pepper
  • Freshly ground black pepper
  • Parmesan cheese (then pop the broccoli under the broiler for a few minutes after it’s fully cooked!)
  • Flaky sea salt

Toss and stir the florets in the oil and salt until they are evenly coated.

When the oven is ready, carefully remove the baking sheet and spread out the frozen, unthawed, broccoli florets, leaving a good amount of room in between them.

Place the baking sheet in the oven and roast for 15-20 minutes. Check at 15 minutes, then stir the broccoli and place back in the oven. Roast for about 5 more minutes, until the broccoli is tender and lightly browned. You may need to cook for a few minutes more if it looks like it needs more time.

Remove from the oven and serve.

Tips for Delicious Roasted Broccoli

Frozen broccoli florets can by default be wetter than the fresh florets at the grocery store. To keep frozen broccoli from getting mushy in the oven, make sure to really space out the florets on your baking sheet. If you check near the end of the cooking time and they don’t seem done, keep cooking (and checking) a little longer to avoid any mushiness.

High heat is key here, as is heating the baking sheet while the oven preheats. Don’t skip this step!

How to Store Leftovers

Leftovers can be stored for a few days in an airtight container in the fridge. The broccoli can be reheated in the oven to help restore its crispness. You could also reheat it in the microwave, but know that it will not be as crisp as if you heat it in the oven.
