Ingredients and substitutions
- Brussels sprouts - Fresh, firm brussels sprouts are best for this recipe. Look for ones that are bright green that are blemish-free. Brussels sprouts are in season through the fall and winter months, so you're likely to find the best ones during this time.
- Parmesan cheese - Freshly grate from a block for best flavor and even melting. Parmesan can also be substituted with your favorite freshly shredded cheese you have on hand.
- Garlic powder - Can be substituted onion powder or with fresh garlic. I recommend thin slicing your garlic instead of mincing because minced garlic can burn quickly in the oven.
- Salt and pepper - Enhances the flavor of your brussels sprouts.
- Olive oil - Can be substituted with ghee or your favorite neutral cooking oil.
How to roast brussels sprouts
- Trim the ends and slice your brussels sprouts in half. Add to a bowl and top with olive oil, seasoning, and parmesan cheese. Toss to coat.
- Spread brussels sprouts onto a baking sheet and spread into a single layer.
- Roast until golden brown and fork tender (or to your desired doneness).
- Optionally, sprinkle on more parmesan just before serving for extra cheesy flavor.
Tips and tricks
Preparing brussels sprouts - Rinse your veggies off and pat dry. Trim the hard stems on the bottom, removing excess or brown parts. This is usually about ¼ inch or less but can vary.
Peel off discolored leaves - If your brussels sprouts have any brown spots or yellow leaves, peel off and discard.
Fresh, green leaves can be roasted - If any green leaves fall off, they can be tossed and roasted with the rest of the brussels sprouts. They get nice and crispy in the oven!
Small brussels sprouts? - If your brussels sprouts are very small (like the size of cherry tomatoes) they can be left whole for roasting. Larger brussels sprouts (large egg or golf ball sized) should be sliced in half for quicker roasting.
Storage
Leftover brussels sprouts will keep for 3 to 4 days in a tightly sealed container in the refrigerator.
Frequently asked questions
Brussels sprouts can get soggy if they're overcooked or you're using frozen, thawed brussels sprouts. Freezing any vegetables will change their structure, making them softer and a bit watery after thawing.
Oven temperatures can vary from oven to oven - yours can run hotter or colder than the next. If your brussels sprouts are large, they'll need additional cooking time. As indicated in the recipe card, continue cooking until they're finished to your preferred texture and color. Test with a fork to ensure your brussels sprouts are fork tender.
