Ingredients You’ll Need
- Brussels sprouts: One pound of fresh Brussels sprouts is ideal. Choose ones with vibrant green leaves and firm texture. If they’re smaller and more tender, cooking time might be slightly reduced.
- Olive oil: One tablespoon of high-quality olive oil adds flavor and helps in browning. Avocado oil can be an excellent substitute if you prefer.
- Salt: Half a teaspoon brings out the natural sweetness in the Brussels sprouts. You can use Himalayan or sea salt if preferred.
- Pepper: Half a teaspoon of freshly cracked black pepper adds a bit of warmth. For a spicier kick, try a pinch of cayenne pepper.
- Onion powder: Half a teaspoon enhances the flavor profile. If you have fresh onions, a tiny amount finely chopped can work too.
- Garlic powder: Half a teaspoon provides that irresistible aroma and taste. Fresh minced garlic is another scrumptious alternative.
- Grated Parmesan cheese: A quarter cup of grated Parmesan not only adds richness but also a delightful crispy finish. Nutritional yeast can be used for a vegan twist, giving a cheesy flavor without dairy.
How to Make Parmesan Roasted Brussels Sprouts
Preheat and Prepare: Begin by preheating your oven to 400°F. The right temperature is crucial for those golden edges everyone loves. Spray a rimmed cookie sheet lightly with nonstick cooking spray. Avoid using foil; we want those sprouts to roast directly, ensuring an even crispiness.
Wash and Trim: Rinse your Brussels sprouts under cold water, then remove the outer leaves and cut off the tough ends. Halve each sprout to ensure even cooking. Aim for similar sizes; this will help them roast uniformly and achieve that golden-brown perfection.
Par-Cook (Optional): If you’re short on time or want to enhance the texture, place the Brussels sprouts in a large microwave-safe bowl and zap them on high for one minute. This quick step makes the roasting phase even faster while helping retain a tender inside.
Toss with Goodies: In that same bowl (or a mixing bowl if you didn’t par-cook), drizzle the sprouts with olive oil, and sprinkle in the salt, pepper, onion powder, and garlic powder. Add the grated Parmesan, and toss everything together until well coated. The assembly of flavors at this stage is a sure sign this dish will be a winner.
Arrange on Sheet: Transfer the seasoned sprouts onto the prepared cookie sheet, placing them cut side down. This helps caramelize those flat sides beautifully, resulting in a lovely crust. Make sure they have a little space to breathe; overcrowded sprouts won’t roast evenly.
Roast to Perfection: Slide the cookie sheet into your preheated oven. Roasting time can vary depending on whether you par-cooked them: about 15-20 minutes for par-cooked or 30 minutes for raw ones. Stir them halfway through to ensure they brown evenly, keeping an eye out until those edges turn a delightful golden hue.

Storing & Reheating
Store leftover Parmesan Roasted Brussels Sprouts in an airtight container at room temperature for up to two hours. If you need to store longer, pop them in the fridge where they’ll last for about 3-4 days. Just ensure they’re cooled before sealing. For those who want to savor these delightful sprout bites later, freezing is an option too. Simply let them cool, then transfer to a freezer bag for up to three months. When you’re ready to enjoy again, reheat them in a 375°F oven for about 10-15 minutes until warmed through, giving them a refreshed texture and flavor.
Chef’s Helpful Tips
- Make sure to trim the Brussels sprouts well—this helps them cook evenly and look appealing.
- Check the temperature of your oven occasionally; some run hotter than others, which can affect cooking time.
- If you prefer them extra crispy, turn on the broiler for a minute or two after roasting, but keep a close eye to avoid burning.
- For a zesty twist, add a squeeze of lemon juice or balsamic glaze right before serving, enhancing flavor effortlessly.
- You can prepare the sprouts ahead of time, seasoning them and placing them on the sheet. Cover and refrigerate until you’re ready to roast.
Brussels sprouts are often underestimated, but when roasted this way, they truly shine. Take a moment to savor those crispy bits, while the tender center surprises your taste buds with its warmth.
Recipe FAQs
Can I use frozen Brussels sprouts for this recipe?
While fresh Brussels sprouts are recommended for the best texture and flavor, you can use frozen ones in a pinch. Just be sure to thaw and drain the excess moisture before seasoning and roasting, as they may not crisp up properly otherwise.
How do I know when the Brussels sprouts are done?
The perfect Brussels sprout is golden brown and can be pierced easily with a fork. Look for a beautifully caramelized exterior, while the interior should be tender but not mushy. A little char adds amazing flavor!
Can I add other vegetables to this dish?
Absolutely! Brussels sprouts pair wonderfully with other roasted veggies like carrots, sweet potatoes, or even cauliflower. Just chop them to a similar size and adjust cooking times as necessary.
Is there a vegan option for this recipe?
Yes! You can simply omit the Parmesan or replace it with nutritional yeast to maintain that cheesy flavor without the dairy. They’ll still be delicious and satisfying without sacrificing texture.
Embrace the flavor and joy that Parmesan Roasted Brussels Sprouts can bring to your table. This simple, straightforward recipe promises to enliven your meal, transforming those little green veggies into a delightful side. Happy cooking!
