Roasted frozen cauliflower is easy to make and comes out caramelized and flavorful. You just need to be patient - it takes a bit longer than fresh.
I'm so grateful for frozen vegetables! They are always there in the freezer, patiently awaiting their turn. When I'm out of fresh veggies, I'm always happy to have them on hand, and roasted frozen cauliflower, caramelized and delicious, is a great example of how good they can be.
Ingredients
See the recipe card for exact measurements. Here are my comments on some of the ingredients.
- Frozen cauliflower: I use two 1-pound bags of cauliflower florets.
- Olive oil spray: I use it to spray the pan and the cauliflower florets. You can use olive oil and drizzle it on the cauliflower, but I like the convenience of spraying and the way it evenly coats the veggies.
- To season: Kosher salt, freshly ground black pepper, garlic powder, and dried thyme.
Instructions
The detailed instructions and step-by-step photos are included in the recipe card. Here's a quick overview.
Scatter the cauliflower florets over a parchment-lined, olive-oil-coated rimmed baking sheet. Spray them with olive oil and season them with spices.
Bake the cauliflower at 400°F until it's golden brown. In my oven, this takes 45-50 minutes. I would start checking after 40 minutes, just in case. Serve immediately.

- Frozen cauliflower florets are typically not all the same size - in fact, they greatly vary in size - but that's fine. Don't worry about it. You can bake them all together.
- Please don't thaw the cauliflower before baking. To preserve its freshness and texture, you should bake it from frozen.
- The main difference between roasting frozen and fresh cauliflower is that frozen cauliflower doesn't crisp up as much as fresh roasted cauliflower. It's tender and buttery, but not crispy.
Serving Suggestions
Since I cook it in a 400°F oven, I like to serve this side dish with an entree I can cook in the same oven. So I often serve it with one of the following:
Storing Leftovers
You can keep the leftovers in an airtight container in the fridge for 3-4 days. I keep them in a glass food storage container, as shown in the photo below. Reheat them gently in the microwave at 50% power, or enjoy them cold in salads. They make a great addition to this simple arugula salad.

Ingredients
- Olive oil spray - extra-virgin
- 2 pounds frozen cauliflower florets
- 1 teaspoon Diamond Crystal kosher salt - or ½ teaspoon of any other salt, including Morton kosher salt
- ¼ teaspoon black pepper
- ½ teaspoon garlic powder
- ¼ teaspoon dried thyme
Instructions
- Preheat the oven to 400°F. Line a rimmed baking sheet with high-heat-resistant parchment paper. Spray the parchment paper with olive oil.
- Arrange the frozen cauliflower florets in a single layer on the prepared baking sheet. They won't all be the same size - that's OK. Don't worry about it.
- Spray the florets with olive oil and sprinkle them with salt, pepper, garlic powder, and dried thyme.
- Bake the florets until golden brown, for 45-50 minutes. Serve immediately.
Notes
- I use olive oil spray to coat the pan and the cauliflower florets. You can use olive oil and drizzle it on the cauliflower, but I like the convenience of spraying and the way it evenly coats the veggies.
- During the last 15 minutes of cooking, you can sprinkle the florets with grated Parmesan.
- To preserve its freshness and texture, bake the cauliflower from frozen.
- You can keep the leftovers in an airtight container in the fridge for 3-4 days. I keep them in a glass food storage container, as shown in the photo below. Reheat them gently in the microwave at 50% power, or enjoy them cold in salads.
