We will talk about how long to bake crispy brussel sprouts at 450 in the oven fresh, or how to cook frozen brussel sprouts for a healthy side dish that is buttery and crispy on the edges.

Not too sure about this controversial vegetable? We’re here to change your mind with this easy brussel sprouts recipe with tons of flavor! If you want to try a new easy side dish this year I challenge you to try this. You won’t be disappointed I promise.
We first shared how to make Instant Pot brussel sprouts last year. Then air fryer brussel sprouts were over the top great. BUT if you don’t have one of those you can make them just as delicious inside your oven.
If you aren’t a believer yet we may transform your tastebuds with these! Live in snowy weather like we do and can’t always find these fresh in your produce section? Us too. That is why we shared frozen brussel sprouts directions here too.

How Long to Bake Brussel Sprouts at 450
That depends on the method you are using and whether they are sliced or not. I will share them all here. At 450 degrees baked you are looking at 18-20 minutes depending on how large they are. Yes, I am aware they’re actually called the best brussels sprouts, with an s. Nobody really calls them that though so let’s go with the every day pronunciation shall we.
How Long to Bake Sliced Brussel Sprouts
It doesn’t take very long if you first slice them in half like this at the beginning. If left whole the texture doesn’t come out right. The outside will get really over done by the time you get the middle as tender as you’d need it to be. 18 minutes is just about right if sliced.
How to Season
Season with salt and pepper of course. Add any other of your favorite seasonings you like on top of that. A bit of heat with chili powder or dry Sriracha is a fave with some people. I wrap my baking sheet in non stick aluminum foil too for an easier cleanup later.
As far as what to add to the top or seasonings for your roasted vegetables that is up to you. Balsamic vinegar works well, a squeeze of lemon juice is an easy one, and parmesan is one of our favorites.
How to Bake Brussel Sprouts Super Crispy
there are a few things you need to remember. First off, moisture = a softer outcome. With this said once you rinse, dry with paper towels. Slice in half and dry again for the best results. This will allow the oil to stick well which will help crisping further as well. If you want them extra crispy switch to the broil setting for 1 minute at the very end.

Tips for Success
If you really want to leave whole, microwave brussel sprouts this way for a few minutes to get them started. They need to be tender but not soggy. There is a very fine line between the two so don’t walk away when you’re baking these.
You want a light golden brown on the top so you get the leaves a bit crispy, but not burned. Adding butter and a bit of vinegar flavor after they’re cooked gives it a punch at the end. Then you can transfer to a pan and make creamy cast iron brussel sprouts.
