Roasted frozen broccoli is the easy vegetable side dish you’ve been dreaming of. There’s no chopping or defrosting and it’s simple to customize with your favorite seasoning blend. Below we’ll show you how to cook it in your oven or toaster oven.
Let’s start with the important stuff…how does roasted frozen broccoli taste? Surprisingly, it’s pretty darn delicious!
To me, the taste and texture are a cross between roasted and steamed broccoli.
- The florets are cooked through and tender without being soggy or mushy. Larger pieces even have a little toothy texture.
- There are fewer crispy bits than with our toaster oven-roasted broccoli but the florets have lots of tasty flavors thanks to the oil and seasonings.
Lately, I’ve been pairing this frozen veggie hack with our quick baked potatoes or quick baked sweet potatoes. I just add the broccoli to the pan after the potato halves have cooked for about 15 to 20 minutes (depending on how large they are).
Topped with cheddar cheese, salsa, and a big dollop of Greek yogurt it makes a great lunch!
- Frozen Broccoli: Florets are best because the pieces are usually about the same size. Whenever I use a mix of cuts (florets and stems) the pieces tend to cook a little unevenly but it’s not a huge difference.
- Oil: Olive oil, grapeseed oil, and avocado oil all work great.
- Seasoning: For an easy option, I like to grab a seasoning blend like Everything Bagel, Old Bay, Za’atar spice mix, or any of Trader Joe’s blends. But feel free to take a tour of your spice cabinet and have some fun.
- Salt and Pepper: These are more of a suggestion. I usually omit the salt if the seasoning blend already includes it.
- Begin by preheating your oven or toaster oven to 400°F. In our traditional oven, I like to use the middle rack. If you’re using a toaster oven, adjust the cooking rack to the bottom placement, and select the BAKE setting.
2. Next, pile the frozen broccoli in the center of a sheet pan. Drizzle with the oil and then sprinkle with the seasoning blend, salt, and pepper. With clean hands, toss everything together to evenly coat the pieces.
3. Before you pop the pan in the oven, take a minute and spread the florets out leaving some space between each piece. If the broccoli is squished together it will steam (instead of roasting) and end up soggy.
4. Roast the broccoli until the side facing the pan begins to brown. For large florets like the ones pictured, this usually takes about 12 to 15 minutes.
5. Use oven mitts to carefully remove the pan and flip the broccoli. Return the pan to the oven and cook until fork-tender with dark roasted bits on the ends, about 5 to 10 minutes more.
Let the broccoli cool for a few minutes. Then give it a taste, adjust the seasonings as desired, and dig in!

Watch your broccoli, not the clock - As frozen broccoli brands differ and ovens vary, you may need to adjust the cooking time. Check on your broccoli early the first few times you cook it and take note of any changes you need to make for your specific oven.
Convection Toaster Ovens - Reduce the temperature to 375°F. Begin checking the first side after 10 to 12 minutes. Flip the broccoli and continue cooking for 5 to 7 minutes more.
Convection Troubleshooting - If you’re finding the broccoli is browning too fast and the inside is cold, try reducing the temperature to 350°F. and increase the cooking time as needed.
Seasoning Ideas - We’ve tried Trader Joe’s 21 Seasoning Salute, Italian Seasoning, Old Bay, and Everything Bagel Seasoning. Powdery parmesan cheese (the kind in the green shaker can) is another great option.
- Once the broccoli is cooked, you can enjoy it plain or topped with fresh lemon juice and grated parmesan.
- To make pizza-style broccoli, dollop marina sauce onto the cooked broccoli and sprinkle with shredded mozzarella cheese and your favorite pizza toppings. Return to the oven for a few minutes to melt the cheese.
