This hearty garlic roasted Brussels sprouts recipe transforms the often-maligned vegetable into a crave-worthy side dish that even skeptics will love. The combination of high-heat roasting and Parmesan creates irresistibly crispy edges while the garlic adds aromatic depth that makes these sprouts utterly addictive.
I discovered this recipe during a holiday dinner crisis when my planned side dish failed. These garlicky sprouts were such a hit that my brother in law who claimed to hate Brussels sprouts asked for seconds and now requests them at every family gathering.
Ingredients
- Fresh Brussels sprouts trimmed and halved: Look for firm bright green sprouts with tightly packed leaves for the best flavor and texture
- Olive oil: provides the perfect medium for roasting and helps achieve that golden exterior. Use a good quality extra virgin for best results
- Minced garlic cloves: add aromatic depth. Fresh garlic is essential here as it caramelizes beautifully during roasting
- Salt and freshly ground black pepper: enhance all the flavors. Sea salt or kosher salt works best
- Freshly grated Parmesan cheese: creates a savory crust. Avoid pre grated varieties which contain anti caking agents
- Optional fresh parsley and lemon wedges: brighten the final dish with color and acidity
Instructions
- Prepare the oven:
- Heat your oven to 425°F and line a baking sheet with parchment paper. This high temperature is crucial for achieving caramelization without steaming the sprouts.
- Season the sprouts:
- Combine the halved Brussels sprouts in a large bowl with olive oil ensuring each piece gets coated. Add the minced garlic salt and pepper tossing thoroughly. The oil coating helps the sprouts crisp up beautifully.
- Arrange for maximum browning:
- Place the sprouts cut side down on your prepared baking sheet leaving space between each piece. This arrangement allows for proper air circulation and ensures the cut surfaces caramelize perfectly.
- Roast to golden perfection:
- Bake for 20 minutes stirring once halfway through. The sprouts should develop deep golden edges and become tender inside. The garlic will become fragrant and lightly golden but not burnt.
- Add the cheese finish:
- Sprinkle the Parmesan evenly over the hot sprouts and return to the oven for 3 to 5 minutes. Watch carefully as the cheese melts and forms a savory golden crust that adds incredible flavor and texture.
- Serve with flair:
- Transfer to a serving dish garnish with fresh parsley if desired and serve with lemon wedges for a bright finishing touch. The acidity of lemon beautifully balances the richness of the cheese.

The garlic is truly the secret weapon in this recipe. I accidentally doubled the amount once when distracted by a phone call and discovered it created an incredible depth of flavor as the garlic caramelized alongside the sprouts. Now I always use extra garlic and consider it my signature twist on this classic preparation.
Selecting Perfect Brussels Sprouts
The foundation of this dish depends on choosing quality sprouts. Look for bright green Brussels sprouts with tightly formed heads that feel firm and heavy for their size. Smaller sprouts tend to be sweeter and more tender, while larger ones can have a stronger flavor. Avoid any with yellowing leaves or soft spots, which indicate age. For maximum freshness, buy them still attached to the stalk if possible, though this is typically only available at farmers markets or specialty stores.
Make-Ahead Options
This dish can be partially prepared ahead of time to streamline your meal preparation. Clean and halve the Brussels sprouts up to two days in advance, storing them in an airtight container in the refrigerator. You can also roast them for the initial 20 minutes earlier in the day, then finish with the Parmesan just before serving by reheating at 425°F for 5-7 minutes. The sprouts will maintain their texture and flavor, making this perfect for busy holiday meals or dinner parties.
Flavor Variations
While this classic version shines with Parmesan and garlic, the recipe serves as a wonderful foundation for creative variations. Try adding a tablespoon of balsamic vinegar before roasting for a sweet-tangy glaze. For a smoky twist, incorporate a teaspoon of smoked paprika or top with crispy bacon pieces after roasting. A sprinkle of red pepper flakes adds gentle heat, while a drizzle of honey before the final roasting creates a delicious sweet-savory balance. For an Asian-inspired version, replace the Parmesan with a mixture of soy sauce, honey, and sesame seeds.
Troubleshooting Tips
If your Brussels sprouts aren't getting crispy enough they may be overcrowded on the baking sheet. Always use a large enough pan to allow space between each piece. Sprouts turning too dark before becoming tender likely means your oven temperature is too high. Use an oven thermometer to verify accuracy. For extra crispy results make sure your Brussels sprouts are completely dry after washing.

Serve immediately for the best crispy texture and flavor. Enjoy these delightful Brussels sprouts as a standout side dish that will surely impress.
