Do I Need To Wash Brussel Sprouts?

Yes, you need to wash Brussel sprouts because many times they come full of dust or dirt. To clean them, rinse them in cold water for 30 seconds or until they are completely clean.

How Long Do You Roast Brussel Sprouts?

It depends on the size of your Brussel sprouts and the power of your oven. But roughly, if you roast Brussel sprouts in the oven at 400°F, you will bake them for 20-30 minutes.

They are ready to eat when the Brussel sprouts are lightly charred, toasted on the bottom, crisp on the outside, and tender on the inside. Also, it’s very possible that the leaves that are loose will be very brown and crispy.

How Do You Prepare Brussel Sprouts For Roasting?

  1. First, rinse the Brussel sprouts in cold water.
  2. Using a sharp knife, trim or cut off the tough brown ends of the Brussel sprouts, and discard them.
  3. Pull off any outer leaves that are yellow. If some green leaves happen to fall off, save them to roast with the Brussel sprouts.
  4. Cut each sprout in half lengthwise.

Ingredients You Need To Make Garlic Parmesan Brussels Sprouts

  • Brussel sprouts — When you pick Brussels sprouts, make sure they are firm, green, and blemish-free. If the sprouts are loose or have yellow leaves, they are past their prime. Brussels sprouts are in season from October through March but you can usually find them at your local grocer year-round.
  • Extra virgin olive oil — I like roasting my Brussels sprouts with olive oil but you can use whatever neutral oil you’d like. Avocado oil is another great option. You can also use melted butter.
  • Garlic — I highly recommend using fresh garlic for the best flavour. It’s soooo much more flavourful and is worth the effort to mince the garlic.
  • Lemon juice — Again, fresh lemon juice is the best way to brighten up the roasted Brussels sprouts. You want the bright, fresh flavours of freshly squeezed lemon juice. Bottled lemon juice does not have the same bright taste. If you don’t like citrus flavor, you can use balsamic vinegar instead.
  • Salt and pepper — A bit for seasoning. I love freshly cracked pepper as it’s more flavourful than pre-ground pepper from a bottle.
  • Parmesan cheese — Shaving your own Parmesan cheese is my go-to! The pre-shredded cheese tends to have preservatives to keep the cheese from clumping so I prefer to grate it myself. Grating the parmesan has a fresher, creamier taste.

How To Make Roasted Brussels Sprouts:

  • Add the sprouts to a bowl and season them with extra virgin olive oil, garlic, lemon juice, salt, and pepper.
  • Toss them really well, and place them on your baking sheet. You can use parchment paper, but I normally don’t use it. Now, the Brussel sprouts are ready to roast.
  • Don’t forget to toss them once halfway through baking.

3 Quick Tips To Make The Perfect Garlic Parmesan Roasted Brussel Sprouts:

  1. Preheat your oven before adding the Brussel sprouts. It helps them become crispy.
  2. Don’t be afraid to use lots of olive oil. It adds more flavor and it makes the Brussels less dry.
  3. Place them in one single layer on the baking sheet with the cut-side-down. This step is important to avoid them becoming soggy.

For this recipe, the only work you have is to clean and cut the Brussel sprouts. This recipe is done in a few minutes and tastes delicious! It goes really well with roasted chicken or a delicious fish recipe and some fluffy rice.


How To Clean And Trim Brussels Sprouts

  1. Cut off the stem end.
  2. While they may look (and taste) like mini cabbages, they do not need to be cored. The core holds them together while roasting.
  3. After trimming the ends, you can clean them in a bowl of cold water. Any sediment left in the sprouts will sink to the bottom.
  4. You can leave them whole, or if they are large, half or quarter them. Just be sure they are similar in size so they cook evenly.
  5. Remove and discard any discolored outer leaves.

More Tips For The Best Brussels Sprouts

  • Make sure you are cutting the Brussels sprouts as evenly as possible. Sometimes it’s difficult as some sprouts are smaller than the rest. Simply keep an eye on them in the oven and use tongs to remove the ones that are browning quickly.
  • If you are purchasing the Brussels sprouts in advance, to keep them fresh, store them unwashed, and untrimmed in a plastic bag in the vegetable crisper drawer of the fridge.
  • Do not overpack the sprouts on the sheet pan. If they are too close together, they will steam instead of roast.
  • I like adding more Parmesan cheese right before serving so it doesn’t all completely melt into the warm Brussels sprouts. There’s no such thing as too much Parmesan cheese.
  • If you want the Brussels sprouts to be a little bit browned, you can turn the broiler on high for the final 3 minutes and broil it. Keep a close eye on it, so that it does not burn.
  • Additional vegetables can be added as well! Just be sure to adjust the size of your pan if you plan on adding more vegetables.
  • After washing the Brussels sprouts, make sure to pat them completely dry so the olive oil will coat the sprouts better and crisp up.

How To Store Brussels Sprouts

  • If you have any of the delicious garlic Parmesan roasted Brussels sprouts leftover, store them in the refrigerator for up to 4 days.
  • I recommend reheating them in the oven. They will only take ten to twelve minutes at 350F to warm through as this keeps them crispier than microwaving them.
  • I don’t recommend freezing the roasted Brussels sprouts as they can become soggy when thawed. If you really would like to freeze this, allow the sprouts to fully cool before transferring them to an airtight freezer-safe container or bag. You can thaw and reheat them in the oven to try and keep them crispy.

Recipe Variations

  • Add a drizzle of honey to make these Brussels sprouts sweeter.
  • Sprinkle a pinch of red chili flakes to add some heat to the sprouts.
  • Mix brown sugar with olive oil for a deeper sweet taste.
  • Fresh herbs are always a delicious addition to any recipe. Some fresh thyme, rosemary, or sage add a tasty layer of flavor to the sprouts.
