How to Cook Frozen Brussels Sprouts (+ Recipe Ideas!)

If you’ve ever wondered how to cook frozen brussels sprouts (or the best way to do it): I’ve got you covered!

Brussels sprouts are a great veggie side dish. They can be served on their own, with other roasted veggies, or in a warm brussels sprouts salad. I even wrote an entire post on how to make brussels sprouts delicious!

But did you know you can roast frozen brussels sprouts? It’s easy and so much tastier than steaming or microwaving them, because brussels sprouts (and all veggies) are best when they’re crispy and not soggy!

And if you’re curious: frozen veggies are just as nutritious as fresh ones… but they give you a lot more flexibility with your meal planning. 🙂

How to Cook Frozen Brussels Sprouts

To cook frozen brussels sprouts, I highly recommend roasting them! It brings out the flavor and crispiness in the best way. Plus, it’s super easy and barely requires any prep work. And you know I’m all about hands-off cooking!

Here are the main steps:

  1. Spread the frozen brussels sprouts on a sheet pan lined with parchment paper (don’t thaw them first!)
  2. Toss with oil + seasoning (feel free to add a pinch of red pepper flakes for a little heat)
  3. Roast in the oven until crispy

You can find the full recipe at the end of this post. But feel free to experiment – most seasonings will go well here!

Brussels Sprouts Nutrition Info

Brussels sprouts are in the same vegetable family as kale and cauliflower.

They’re packed with nutrients like fiber (which is very important for digestive health), vitamin K, vitamin C, and antioxidants (which help lower the risk of chronic disease).

They also contain omega-3 fatty acids – in fact, they’re one of the best plant-based sources.

So, all in all, Brussels sprouts are practically little nuggets of nutrients!

Are Frozen Veggies as Healthy as Fresh Ones?

This is a question I see a lot, and the answer is yes: frozen veggies are just as healthy (if not more so)!

In fact, they’re flash frozen at peak freshness. And with the convenience of lasting a lot longer when stored than fresh veggies, that’s all the more reason to stock up!

The way you cook the veggies also matters. Roasting them (as opposed to boiling them) helps them keep more of their nutrients.

Plus, that way they’re crispier!
