Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
To make these mouthwatering Brussels sprouts, you’ll need just a handful of simple, wholesome ingredients: fresh Brussels sprouts, olive oil, minced garlic, grated Parmesan cheese, salt, pepper, Italian seasoning, and optional red pepper flakes for a touch of heat. For an extra pop of brightness, consider adding some lemon zest before serving.
When choosing your ingredients, opt for high-quality options whenever possible. Freshly grated Parmesan makes a world of difference compared to pre-shredded varieties, which often contain anti-caking agents that affect texture. If you’re feeling indulgent, swap olive oil for melted butter—it adds a rich, luxurious flavor that pairs beautifully with the sprouts.
Instructions
Making these Brussels sprouts is so straightforward, you might wonder why you haven’t tried it sooner. Here’s how to whip up this crowd-pleasing dish:
- Preheat the Oven
Start by preheating your oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease it to prevent sticking. A hot oven ensures your sprouts get nice and crispy! - Prepare the Brussels Sprouts
Trim the ends of the Brussels sprouts and cut them in half lengthwise. Halving them exposes more surface area, allowing for maximum caramelization during roasting. Be sure to pat them dry with a paper towel if they’re damp—dry sprouts = crispy results! - Season Generously
In a large bowl, toss the halved sprouts with olive oil, minced garlic, salt, pepper, Italian seasoning, and red pepper flakes (if using). Make sure each piece is evenly coated for consistent flavor. - Roast to Perfection
Spread the seasoned sprouts cut-side down on the prepared baking sheet. This technique helps achieve those coveted crispy edges. Roast for 20 minutes, then sprinkle with grated Parmesan. Return to the oven for another 5 minutes to let the cheese melt and crisp slightly. - Garnish and Serve
Once done, transfer the sprouts to a serving dish. Garnish with freshly chopped parsley and a sprinkle of lemon zest for a fresh, zesty finish. Serve immediately while warm and enjoy every bite!

Tips and Tricks
Here are some insider tips to take your Brussels sprouts game to the next level:
- Go for Extra Crispy: If you love ultra-crispy sprouts, broil them for 1-2 minutes at the end of cooking. Just keep a close eye to avoid burning!
- Use Fresh Ingredients: Fresh garlic and herbs elevate the flavors significantly compared to dried or powdered versions.
- Don’t Overcrowd the Pan: Give your sprouts plenty of space on the baking sheet. Crowding leads to steaming instead of roasting, resulting in soggy sprouts.
- Experiment with Add-Ins: Toss in toasted nuts like almonds or pecans for added crunch, or drizzle with balsamic glaze for a sweet-tangy twist.
Storage Instructions
Leftovers? Lucky you! Store any remaining Brussels sprouts in an airtight container in the refrigerator for up to 3 days. While freezing isn’t recommended due to texture changes, reheating is a breeze. Simply warm them in a 375°F oven for 5-7 minutes or pop them into an air fryer at 350°F for 3 minutes. They’ll regain their crispiness and taste just as good as fresh out of the oven.
Serving Suggestions
These Garlic Parmesan Roasted Brussels Sprouts are incredibly versatile. Pair them with grilled chicken for a weeknight dinner, serve them alongside roasted salmon for a healthy option, or bring them to a holiday feast as a standout side dish. Feeling adventurous? Drizzle them with honey or balsamic reduction for a sweet-and-savory combo that’s sure to impress.
Variations
One of the best things about this recipe is its adaptability. Here are a few ideas to customize it based on your preferences:
- Spicy Kick: Add extra red pepper flakes or a dash of hot sauce for those who love heat.
- Balsamic Bliss: Finish with a drizzle of balsamic glaze for a tangy-sweet note.
- Nutty Crunch: Sprinkle toasted almonds, walnuts, or pecans over the top for added texture.
- Air Fryer Option: Cook at 375°F for 12-15 minutes, shaking halfway through, for perfectly crispy sprouts without turning on the oven.
