Ingredients

For perfect Garlic Parmesan Roasted Brussels Sprouts, gather these simple but essential ingredients:

• 1½ pounds (680g) fresh Brussels sprouts, trimmed and halved
• 3 tablespoons (45ml) extra virgin olive oil
• 4 cloves garlic, minced (about 2 tablespoons)
• ½ cup (50g) freshly grated Parmesan cheese, plus extra for serving
• 1 teaspoon (5g) kosher salt
• ½ teaspoon (2g) freshly ground black pepper
• ¼ teaspoon (1g) red pepper flakes (optional)
• 1 tablespoon (15ml) fresh lemon juice

Select fresh, firm Brussels sprouts for the best results. Look for bright green heads with tightly packed leaves. The fresher your sprouts, the crisper and more flavorful your finished dish will be. For the Parmesan, using freshly grated rather than pre-packaged will provide superior melting and a more authentic flavor in your roasted brussels sprouts with garlic.

Pro Tips

Tip 1: Perfect Brussels Sprout Preparation
The key to exceptional Garlic Parmesan Roasted Brussels Sprouts starts with proper preparation. Always trim the woody stems and remove any discolored outer leaves. For even roasting, cut sprouts of similar size in half, while leaving tiny ones whole. This creates more surface area for caramelization and allows the garlic parmesan coating to cling better to each piece.

Tip 2: Master the Roasting Temperature
Roast at 425°F (220°C) for optimal results. This high temperature creates the perfect environment for quick caramelization without burning the garlic or cheese. If your sprouts aren’t browning well, position your rack in the upper third of the oven where it’s slightly hotter. Never crowd the baking sheet – use two pans if necessary, as overcrowding creates steam that prevents proper crisping.

Tip 3: The Perfect Timing Technique
Add the Parmesan cheese during the last 5 minutes of roasting for the perfect cheese-to-sprout integration. This prevents burning while allowing the cheese to melt and create those irresistible crispy edges. Always toss your brussels sprouts with fresh lemon juice immediately after removing from the oven – the acid brightens the flavors and cuts through the richness of the roasted vegetable and cheese.

Instructions

Step 1: Prepare The Brussels Sprouts
Preheat your oven to 425°F (220°C) and position a rack in the upper third. Start by thoroughly washing your Brussels sprouts under cold water. Using a sharp knife, trim the woody stem ends and remove any discolored outer leaves. Cut each sprout in half lengthwise through the stem. For especially large sprouts, quarter them to ensure even cooking. Pat the prepared sprouts completely dry with paper towels – this crucial step ensures they’ll roast rather than steam.

Step 2: Season Generously
In a large mixing bowl, combine your halved Brussels sprouts with olive oil, minced garlic, salt, black pepper, and red pepper flakes if using. Toss thoroughly until every sprout is evenly coated with the seasoning mixture. Your hands are the best tools here – really get in there and massage the oil and seasonings into all the nooks and crannies of the sprouts.

Step 3: Arrange For Perfect Roasting
Transfer your seasoned Brussels sprouts to a large rimmed baking sheet. The key here is spacing – arrange them in a single layer with cut sides facing down, ensuring they’re not touching or overcrowded. Leave enough space between each piece to allow hot air to circulate. If necessary, use two baking sheets rather than cramming everything onto one.

Step 4: Roast To Perfection
Place your baking sheet in the preheated oven and roast for 15 minutes. After this initial cooking period, remove the sheet and carefully flip each Brussels sprout. The cut sides should now be deliciously golden brown. Return to the oven and continue roasting for another 5-7 minutes until the sprouts are tender when pierced with a fork.

Step 5: Add The Parmesan Finish
Remove the baking sheet from the oven and immediately sprinkle the freshly grated Parmesan cheese evenly over the hot Brussels sprouts. Return to the oven for a final 3-5 minutes, just until the cheese melts and begins to turn golden in spots. Watch carefully during this final stage to prevent burning.

Step 6: Final Flourish
Remove your Garlic Parmesan Roasted Brussels Sprouts from the oven and immediately drizzle with fresh lemon juice. Toss gently to coat everything evenly. Transfer to a serving dish, sprinkle with additional freshly grated Parmesan if desired, and serve immediately while still hot and crispy.

Variations

Honey Balsamic Twist
Transform your Garlic Parmesan Roasted Brussels Sprouts with a sweet-tangy profile by adding 2 tablespoons of balsamic vinegar and 1 tablespoon of honey to the seasoning mix. After roasting, the balsamic caramelizes beautifully, creating a glossy glaze that pairs wonderfully with the naturally nutty flavor of the roasted brussels sprouts with garlic. The honey balances the vinegar’s acidity while enhancing caramelization for extra crispy edges.

Bacon Lover’s Delight
For an indulgent variation, add 4 ounces of diced bacon to your baking sheet along with the brussels sprouts. The rendering bacon fat infuses the vegetables with smoky flavor while creating extra crispy sprouts. Reduce the olive oil to 1 tablespoon since the bacon will release its own fat. The parmesan garlic brussels sprouts take on an entirely new dimension with this savory addition that makes them utterly irresistible.

Vegan-Friendly Option
Create a dairy-free version by substituting nutritional yeast for the Parmesan cheese (use about 3 tablespoons). Add 1 teaspoon of garlic powder in addition to the fresh garlic for an intensified flavor profile. For extra umami depth, include 1 tablespoon of white miso paste in your seasoning mixture. This variation maintains all the savory satisfaction of the original while accommodating plant-based dietary preferences.

Storage and Serving

These Garlic Parmesan Roasted Brussels Sprouts are best enjoyed immediately after roasting when they’re at peak crispiness. However, leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, avoid the microwave which will make them soggy. Instead, place them on a baking sheet in a 375°F (190°C) oven for 5-7 minutes until warmed through and crispy again.

For serving, these versatile sprouts pair magnificently with roasted meats, especially beef tenderloin or roast chicken. They make an exceptional holiday side dish but are simple enough for weeknight dinners. Try serving them atop creamy polenta with a poached egg for a complete vegetarian meal. Alternatively, add them to a grain bowl with quinoa, roasted sweet potatoes, and a tahini dressing for a nutritious lunch option.

For an elegant presentation, serve your parmesan garlic brussels sprouts on a warmed platter drizzled with high-quality extra virgin olive oil and scattered with additional cheese shavings and fresh herbs.

FAQs

Why are my Brussels sprouts not getting crispy?
The most common culprits are overcrowding your baking sheet or not drying the sprouts thoroughly before roasting. Moisture creates steam which prevents proper caramelization. Also, ensure your oven is fully preheated to 425°F and that you’ve placed the sprouts cut-side down initially.

Can I use frozen Brussels sprouts for this recipe?
While fresh is preferred for optimal crispiness, frozen can work in a pinch. Do not thaw them first—roast them directly from frozen, adding about 5-7 minutes to the cooking time. Note that frozen sprouts will never get quite as crispy as fresh ones.

How do I prevent the garlic from burning?
If you find the minced garlic burns during the long roasting process, try tossing the sprouts with olive oil, salt, and pepper first, then adding the garlic and Parmesan during the last 10 minutes of roasting.

Can I make these ahead for a dinner party?
Yes, but with a modification: Roast the sprouts until they’re almost done (about 5 minutes short of completion), then cool and refrigerate. Before serving, roast at 425°F for 5-7 minutes, then add the Parmesan for the final few minutes.

What’s the best cheese substitute if I don’t have Parmesan?
Pecorino Romano or Grana Padano make excellent substitutes with similar properties. For a different but delicious flavor, try Asiago or aged Manchego, which offer comparable nuttiness and melt beautifully.

These Garlic Parmesan Roasted Brussels Sprouts are comfort food at its finest — crispy, savory, and utterly addictive with their perfect balance of garlic, cheese, and caramelized vegetable goodness.
