Ingredients in Roasted Brussels Sprouts
With only a few ingredients and five minutes of prep time, this is sure to be one of your new favorite recipes. I hope this recipe will become a weeknight favorite at your house like it is at mine.
Here are the ingredients you’ll need to make roasted brussels sprouts:
- Fresh brussels sprouts. When you are shopping, look for brussels sprouts that are vibrant green, tightly closed, and on the smaller size. Smaller sprouts will cook more quickly than the larger sprouts.
- Olive Oil. You’ll need a decent amount of oil to roast the brussels sprouts. I use about 3 tablespoons. It may seem like a lot, but it really helps get the sprouts brown and crispy.
- Salt and Pepper.
How to Trim Brussels Sprouts
For this recipe, it’s best to prepare the fresh brussels sprouts by trimming and halving them. If your sprouts are still attached to the stalk, cut them off first. Then, give them a good rinse.
To trim: Using a sharp paring knife, trim off the bottom (stem end) of each Brussels sprout. Then, cut each Brussels sprout in half lengthwise, from tip to trimmed end. Remove any yellow or damaged leaves.
Flavor Variations for Roasted Brussels Sprouts
For this basic recipe, I call for just salt and pepper as the seasonings. But, this recipe is easy to change up by adding your favorite herbs and spices. I encourage you to add more flavors and seasonings to suit your taste. Here are some ideas.
- Add a few cloves of minced garlic, or 1/2 teaspoon of garlic powder to the brussels sprouts before roasting
- Add up to a tsp of dried herbs, or an all-purpose herb blend.
- Add a tbsp of balsamic vinegar to the sprouts before roasting. Add it to the bowl when you’re tossing the sprouts in the olive oil. (This is so good!)
- Add up to 1/2 cup of grated Parmesan cheese to the sprouts, towards the end of the cooking time. This way it will melt and brown, but not burn in the high heat of the oven.
How to Make Roasted Brussels Sprouts
Making oven-roasted brussels sprouts is very simple. After a few minutes of prep, the oven takes care of the rest of the work for you.
To start, wash and dry the sprouts thoroughly. Trim the stem end of the sprouts, and cut them in half lengthwise. Try to keep the size of the pieces relatively uniform so they will cook evenly.
Then, in a large mixing bowl, toss the halves with olive oil, garlic, salt and pepper to taste. Now is the time to add any additional seasonings, like Balsamic vinegar, red pepper flakes, herbs, or other seasonings.
Next, place the halved sprouts on a large rimmed baking sheet. Spread it out in a single layer, being careful not to overcrowd the pan.
For the most crispy Brussels sprouts, you can take an extra minute of time to flip each one cut side down. This is an optional step, of course.
Finally, roast the brussels sprouts in a hot oven for about 20-25 minutes, or until they are tender and caramelized. You’ll know they are done when the brussels sprouts look crispy and lightly charred on the outside.
Tips for the Best Roasted Veggies
- Make sure that the brussels are dry after rinsing them. You can use a salad spinner or pat them down with paper towels.
- Be generous with the olive oil. Toss the sprouts to make sure that they are coated in a thin layer of oil. The oil will make sure that they cook and brown well.
- Don’t overcrowd the pan. It’s important to spread the brussels sprouts halves out into a single layer on a large pan. You can use two pans if you don’t have one pan that is large enough to hold all of it at once. If you crowd the pan, the sprouts will end up steaming and you won’t get brown and crispy edges.
- Use a high enough oven temperature. 400F is the sweet spot in my oven. You may want to buy an oven thermometer if you aren’t sure if your oven is accurate.
- Shake the pan, or use a spatula to toss the brussels sprouts about halfway through the cooking time for even cooking.
How to Store and Reheat Roasted Brussels Sprouts
- To store. Place cooked Brussels sprouts in a tightly lidded storage container in the refrigerator for up to 3 days.
- To reheat. For the best texture, you can reheat these brussels sprouts in the oven. Place them on a rimmed baking sheet, and reheat in the oven at 350 degrees F for 5-10 minutes, until heated through. For a faster method, you can reheat them in the microwave, though the texture will be a bit softer.
