Preheat the oven to 400 degrees F, and add in a large bowl.
Toss the Brussels sprouts with the olive oil, salt, and black pepper cut side down, and spread them on a sheet pan evenly.
Roast for 25 to 30 minutes you can give 5 minutes more if the size is large until they’re browned and caramelized on the bottom, edges, and tender.
If the Brussels sprouts are not browned on the cut side, again cook for another 3 to 4 minutes, until crispy and well-browned. Make sure they don’t get over-cooked.
Serve on time while warm, and enjoy with other main dishes!
Some sauces, such as soy sauce or barbecue sauce, can change the color of Brussels sprouts while cooking. To avoid these pitfalls, roast them simply, add just oil and salt, and toss with more tasty sauces after cooking. They are sautéed in little oil and butter, but this helps them to prepare crisply and only adds to the taste.
