Why This Recipe Works
The secret to perfect Brussels sprouts lies in high-temperature roasting and proper spacing. Cutting them in half doubles the surface area for caramelization, while the 425°F temperature creates those coveted crispy edges without drying out the centers. The initial oil coating protects the leaves from burning while ensuring even browning and maximum flavor development.
How to Select Fresh Brussels Sprouts
Visual Inspection Tips:
- Choose bright green heads with tightly packed leaves
- Avoid yellowing leaves, which indicate age
- Skip any with black spots that could signal fungus
- Select smaller sprouts for tenderness and sweetness
- Fresh-on-stalk varieties offer peak freshness
Ingredients
- Red onion (optional) – Contributes sweetness and additional caramelization when roasted alongside
- Fresh Brussels sprouts – Provide the base vegetable with nutty flavor that develops during roasting
- Olive oil – Creates crispy edges and prevents leaves from drying out during cooking
- Kosher salt – Enhances natural flavors and helps achieve proper caramelization
- Black pepper – Adds subtle heat and complements the nutty Brussels sprouts flavor
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
There are a few steps to preparing Brussel sprouts for baking.
- 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.
- 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.
- 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.
- 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.
- 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.
Even if you think you don’t like Brussel sprouts or have never had them, roasting them will make you a big fan. Let me know if you try them!
These roasted Brussel sprouts are golden and caramelized on the edges, but not dried out. They’re simple to make, and a great side for many meals.

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)
Thanks!
I would defrost them first, and then as you said drain them, they won’t roast well if too much water is left in them.
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!
That sounds great!
