Roasted Brussels Sprout Halves

There's something almost magical about the moment when Brussels sprouts transform in the oven—that unmistakable smell of caramelizing edges filling your kitchen is the sign that something wonderful is happening. I discovered this roasting method by accident, honestly, when I burned a batch so badly that the charred bits actually tasted incredible, crispy and nutty in a way that changed how I thought about these little green vegetables forever. Now I roast them intentionally, chasing that perfect balance between tender insides and crackling outsides that makes even skeptics ask for seconds.

I made these for my sister's first Thanksgiving as a vegetarian, and she got a little emotional when she realized the sprouts weren't just an afterthought side—they were the star of her plate. Watching someone's face light up when they taste properly roasted vegetables instead of the limp, boiled versions they grew up dreading is one of those small kitchen victories that reminds me why I love cooking.

Ingredients

• Brussels sprouts, 500 g (1.1 lbs), trimmed and halved: The key is cutting them evenly so they roast at the same pace; leave the stem end intact so the leaves stay connected.
• Olive oil, 2 tbsp: This is what creates the golden, crispy exterior, so don't skimp or use a light hand here.
• Sea salt, 1/2 tsp: It enhances the natural sweetness that emerges during roasting.
• Freshly ground black pepper, 1/4 tsp: Coarse pepper adds little bursts of flavor that finely ground pepper can't match.
• Garlic powder, 1/4 tsp (optional): If you use it, sprinkle it evenly or some bites will taste garlicky while others don't.
• Chili flakes, 1/4 tsp (optional): A whisper of heat rounds out the earthiness of the sprouts beautifully.
• Parmesan cheese, 2 tbsp grated (optional): Adds a salty, umami finish; use freshly grated for better melting and flavor.
• Fresh parsley, 1 tbsp chopped (optional): The fresh green brightness cuts through the richness of the roasted vegetables.
• Lemon zest, from 1/2 lemon (optional): Just a touch of citrus lifts the entire dish without making it taste lemony.

Instructions

Preheat and prepare:

Set your oven to 220°C (425°F) and line a baking sheet with parchment paper so cleanup is effortless and nothing sticks. A hot oven is essential for that caramelization magic.

Dress the sprouts:

Toss your halved sprouts in a bowl with olive oil, salt, and pepper, making sure every piece gets coated evenly—this is where the texture begins. If you're using the optional garlic powder or chili flakes, mix them in now.

Arrange cut-side down:

Spread the sprouts on the baking sheet in a single layer with the cut sides facing down; this flat surface is what creates those crispy, caramelized edges you're after. Resist the urge to move them around right away.

Roast with patience:

Roast for 20–25 minutes, flipping halfway through so the rounded sides get some color too and the bottoms don't burn. You'll know they're ready when the edges are dark and crispy and a fork pierces the flesh easily.

Finish and serve:

Pull them from the oven and while they're still warm, scatter Parmesan, parsley, and lemon zest over the top if you're using them. Serve right away while they're at their crispiest.

Pin it

I once served these roasted sprouts to my neighbor who'd mentioned in passing that he hated all vegetables, and he ate more than half the batch before catching himself. He looked genuinely confused, like something wasn't fair about vegetables tasting this good, and it became our running joke all winter.

The Secret to Perfect Caramelization

The oven temperature really matters here—220°C gives you enough heat to develop those crispy, browned edges without cooking the insides to mush. If your oven tends to run cool, you might need to bump it up slightly, or if it runs hot, watch them a minute or two closer so they don't char too much on the bottom.

Simple Variations That Work

Once you master the basic roast, the flavor possibilities expand in exciting directions. A drizzle of balsamic glaze after roasting adds a subtle sweetness that feels almost decadent, or you can toss them with a bit of maple syrup before serving for a gentle sweetness that surprised even my most skeptical tasters.

Making It Your Own

The beauty of this recipe is how it adapts to what you have on hand and what you're in the mood for. Fresh herbs like thyme or rosemary scattered over before roasting add an herbaceous depth, while a handful of toasted nuts tossed in right before serving brings a satisfying crunch that makes this feel more substantial.

• For a vegan version, simply skip the Parmesan or use a plant-based alternative and the dish tastes equally delicious.
• Keep the lemon zest ready even if you forget the other garnishes—it's genuinely transformative in just a light dusting.
• Make extra because cold roasted Brussels sprouts are a great snack the next day and toss beautifully into salads.
