Frozen broccoli bakes in the oven in about 20 to 25 minutes at 425°F (220°C).
 
That’s the short answer if you’re rushing to get dinner on the table.
 
But how long to bake frozen broccoli in the oven depends on a few things like the size of the florets, whether you thaw it first, and how crispy you like it.
 
If you’ve ever wondered how long to bake frozen broccoli in the oven without turning it into a soggy mess, you’re in the right place.
 
In this post, we’ll break down exactly how long to bake frozen broccoli in the oven, the best temperature to use, and simple tricks that make frozen broccoli taste freshly roasted.
 
Let’s get into it.
 

How Long to Bake Frozen Broccoli in the Oven

Baking frozen broccoli in the oven is straightforward once you know the timing.
 
Here’s what to expect when you bake frozen broccoli at the right temperature.
 

1. The Standard Baking Time Is 20 to 25 Minutes

At 425°F (220°C), frozen broccoli typically takes 20 to 25 minutes to bake.
 
Small florets may be ready closer to 18 minutes, while larger pieces need the full 25.
 
This is the sweet spot where the broccoli gets tender inside and crispy at the edges.
 

2. Thawed Broccoli Bakes Faster

If you thaw your frozen broccoli first, the baking time drops to about 15 to 18 minutes.
 
Thawing removes excess ice, which is the main reason frozen broccoli turns soggy in the oven.
 
Just spread it on a paper towel, pat it dry, and it’ll roast much quicker.
 

3. Smaller Pieces Cook Quicker Than Big Ones

The size of your florets matters when you bake frozen broccoli.
 
Baby florets can finish in 15 minutes, while thick stalks need the full 25 or even a few minutes more.
 
So when you’re figuring out how long to bake frozen broccoli in the oven, check your pieces first.
 

Best Temperature to Bake Frozen Broccoli

Temperature is half the battle when you bake frozen broccoli in the oven.
 
Here’s how to pick the right heat.
 

1. 425°F (220°C) Gives the Best Results

This high heat roasts frozen broccoli fast enough that the ice melts and evaporates before the broccoli steams itself.
 
The result is a crispy, slightly charred edge with a tender center.
 

2. 400°F (200°C) Works If You Prefer Softer Broccoli

Lower the heat slightly and you’ll get softer, more steamed-tasting broccoli.
 
Just add 5 extra minutes to the bake time.
 

3. Don’t Go Below 375°F (190°C)

Anything lower and the broccoli releases too much water before it browns.
 
That’s how you end up with a limp, watery tray instead of roasted broccoli.
 

Tips for Perfect Oven-Baked Frozen Broccoli

Once you know how long to bake frozen broccoli in the oven, a few extra steps make all the difference.
 

1. Dry It Before Baking

Pat the frozen broccoli dry with a paper towel or let it sit at room temperature for 10 minutes.
 
Less surface ice means crispier broccoli every time.
 

2. Preheat the Pan and the Oven

A hot baking sheet gives the broccoli an instant sear.
 
Preheat your pan for 5 minutes before adding the broccoli, and always preheat the oven fully too.
 

3. Don’t Crowd the Tray

Spread the frozen broccoli in a single layer with space between each piece.
 
Crowded broccoli steams instead of roasts, so use two trays if you need to.
 

4. Toss With Oil and Seasoning

A tablespoon or two of olive oil helps the broccoli brown and keeps it from sticking.
 
Add salt, pepper, garlic powder, or a squeeze of lemon for flavor.
 

5. Flip Halfway Through

Flip the broccoli at the 12-minute mark so every side gets crispy.
 
This simple step is the secret to evenly baked frozen broccoli.
 

So, How Long to Bake Frozen Broccoli in the Oven?

Frozen broccoli bakes in the oven in about 20 to 25 minutes at 425°F (220°C).
 
That’s the timing that gives you crispy edges and tender florets without the soggy texture frozen broccoli is famous for.
 
Thawed broccoli takes 15 to 18 minutes, smaller florets finish faster, and a hot pan plus a single layer on the tray makes all the difference.
