How to Roast Frozen Broccoli
Are you looking for a quick and nutritious side dish that packs a flavorful punch? Roasting frozen broccoli is an excellent way to turn a simple vegetable into a delightful addition to your meal. It’s incredibly easy, requires minimal ingredients, and is perfect for busy weeknights or meal prepping. With a few simple steps, you can have perfectly roasted broccoli that retains its vibrant color and crunch.
Why It Deserves a Spot

Roasting frozen broccoli offers a unique combination of convenience and taste. Frozen broccoli is picked and frozen at its peak ripeness, ensuring that you get a nutrient-packed vegetable without the hassle of washing and chopping fresh produce. When roasted, the natural sugars in the broccoli caramelize, enhancing its flavor and creating crispy edges that contrast beautifully with its tender interior. Plus, it’s a versatile side that pairs well with many main dishes, making it a fantastic addition to your recipe repertoire.
What We’re Using
To create this delicious roasted broccoli, you’ll need the following ingredients:
- 16 ounces frozen broccoli: This is the star of the dish. Make sure to choose high-quality frozen broccoli for the best results.
- 3 tablespoons olive oil: This helps to crisp up the broccoli and adds a lovely flavor.
- 1/2 teaspoon kosher salt: Essential for enhancing the natural flavors of the broccoli.
- Fresh ground pepper: A pinch or two to add a bit of spice.
- 1 lemon (optional): For a zesty finish, adding brightness to the dish.
- 2 tablespoons Parmesan cheese (optional): A sprinkle of cheese can elevate the flavor even more.
Tools of the Trade
Before you begin, gather the necessary tools to make the process seamless:
- Baking sheet: Choose a large, rimmed baking sheet to allow the broccoli to spread out evenly.
- Parchment paper (optional): Lining the baking sheet can make for easier cleanup.
- Spatula: For flipping the broccoli halfway through roasting.
- Measuring spoons: To ensure you add the right amount of oil and seasonings.
- Microplane or grater: If you’re using fresh lemon zest or Parmesan cheese.
Stepwise Method: How to Roast Frozen Broccoli

Step 1: Preheat Your Oven
Start by preheating your oven to 425°F (220°C). A hot oven is crucial for achieving that crispy texture we all love.
Step 2: Prepare the Broccoli
Take the frozen broccoli out of the freezer. There’s no need to thaw it! Spread the broccoli evenly on the baking sheet.
Step 3: Drizzle with Olive Oil
Pour the olive oil over the frozen broccoli. Use your hands or a spatula to toss the broccoli, ensuring it’s evenly coated in oil.
Step 4: Season the Broccoli
Sprinkle the kosher salt and fresh ground pepper over the broccoli. Toss again to distribute the seasonings.
Step 5: Roast in the Oven
Place the baking sheet in the preheated oven. Roast for about 20-25 minutes, flipping the broccoli halfway through to ensure even cooking. You want it to turn golden and slightly crispy around the edges.
Step 6: Add Optional Toppings
If you’re using lemon, zest it over the broccoli just before serving for a bright, fresh flavor. For a cheesy twist, sprinkle the Parmesan cheese over the broccoli in the last 5 minutes of roasting.
Step 7: Serve and Enjoy!
Once the broccoli is crispy and tender, remove it from the oven. Serve it hot as a delightful side dish or mix it into your favorite grain bowl.
