Learn how to roast Brussel Sprouts

Many people wonder how to cook Brussel sprouts. Roasting is the best way to bring out the tasty, slightly nutty flavors in Brussels sprouts. And, it’s so easy.

All you have to do is put them on a roasting tray, slather them in olive oil, and let them hang out in the oven for about half an hour. The result is delicious, and even those family members who claim not to like Brussels sprouts will enjoy them.

Cooking Brussel sprouts in the oven gives them a crunch and a char. The best parts are those charred pieces!

Making a big pan of these is one of my staples for a weeknight dinner, and it’s a hit every time.

How to Pick Fresh Brussels Sprouts

It’s very easy to pick out the freshest Brussels Sprouts, here are 4 tips in picking out the best ones at your grocery store.

  1. Color is everything. You want to look for heads that are bright green and firm with tightly packed leaves. Avoid Brussels sprouts that have yellowing leaves because this is a sign that they are a bit old.
  2. If they have black spots, this could indicate the presence of fungus.
  3. Go for the smaller Brussels sprouts as they are usually more tender and sweeter than larger ones.
  4. If you can find them still on the stalk, they are the freshest.

The key to roasting fresh vegetables

The key to roasting vegetables is to roast them at a high temperature and space them out on the roasting sheet. If the veggies are touching or on top of each other, you will end up with steamed vegetables and not properly roasted ones.

Your baked Brussels sprouts should be golden brown and caramelized around the edges, but still nice and tender in the center. Sometimes people roast them for too long in order to get them golden, but then they dry out.

CopyKat Tip: Make sure that the Brussel sprouts are not overlapping or touching each other on the baking sheet. You want to spread them out so that they can crisp up and get a bit charred on the outside. If they are touching each other and you have crammed in too many, you will end up steaming them.

How to Prep Brussel Sprouts

When baking Brussel sprouts there are a few steps you need to take to prepare these green delights for cooking.

  1. Wash Brussel Sprouts. Wash off any dirt and peel off any yellow leaves, it’s ok if a few are loose, or a few fall off.
  2. Cut the stem off. The stem is the part that attaches to the stalk when growing. This portion can be tough because it dries out after cutting from the stalk.

  3. Cut your Brussel Sprout in half to more than double the space that can get caramelized while cooking. It’s the caramelized bits that taste so good. Also, you can check and make sure everything in the Brussel Sprout is good.

  4. Coat the Brussel sprouts with oil and season. I toss the cut Brussel Sprouts and red onions into a bowl. I add oil to them and stir them before I season them with salt and pepper. This keeps the leaves from drying out while cooking, and it gives the seasoning the ability to stick so the seasoning stays on while cooking.
  5. Spread oil on the baking sheet. Before placing them in the pan, I drizzle a bit of oil in the pan, and I make the sheet pan has a layer of oil on it. When the cut side is placed down in the pan, you know it’s going to brown beautifully.

    I impulsively added Balsamic vinegar t my sprouts at Thanksgiving and even the six year olds loved them. Glad what I considered a mistake before hand turned out so well. Also glad to see others use the same and I’m not crazy.

    Hi Stephanie! Another great recipe!

    Just wondering if frozen Brussels Sprouts can be used, or would they be too watery? (I would cut and ‘drain’ them first)

    Try finishing them off by melting butter in a frying pan, then as they start to blacken add real maple syrup and fry on medium heat for about 5 minutes. Delicious!
