Ingredients You’ll Need

What makes this recipe stand out is how straightforward and accessible the ingredients are, yet each one plays an essential role in creating that perfect balance of crispiness, tang, and savory depth. From the olive oil that crisps the sprouts to the lemon and Parmesan that add vibrant flavor and richness, every item on this list contributes to deliciousness in its own way.

• Brussels sprouts (1 ½ lbs): Fresh and halved for maximum surface area to crisp up beautifully in the oven.
• Olive oil (3 tbsp): Helps achieve that irresistible golden-brown crust and keeps the sprouts moist inside.
• Salt (½ tsp): Enhances the natural flavors and balances the brightness of lemon and richness of cheese.
• Black pepper (½ tsp): Adds a subtle kick that complements the garlic and paprika.
• Garlic powder (1 tsp): Provides aromatic depth and a gentle savory note without overwhelming the sprouts.
• Smoked paprika (½ tsp, optional): Introduces a smoky warmth that pairs perfectly with the roasted flavor.
• Freshly grated Parmesan (½ cup): Brings a salty, nutty richness that melts into the sprouts as you toss them.
• Lemon zest (zest of 1 lemon): Infuses the dish with fresh, citrusy brightness that cuts through the richness.
• Lemon juice (1–2 tbsp): Adds acidity to brighten and lift every bite.
• Melted butter (1 tbsp, optional): For extra silkiness and indulgence.
• Chopped parsley (1 tbsp, optional): Adds a fresh, herbaceous finish and a bit of color contrast.

How to Make Crispy Lemon Parmesan Roasted Brussels Sprouts

Step 1: Prep the Brussels Sprouts

Start by preheating your oven to 425°F (220°C) to get it nice and hot, which is key for crispiness. Meanwhile, rinse and trim your Brussels sprouts, then slice them in half. Toss them thoroughly with olive oil, salt, black pepper, garlic powder, and if you’re using it, smoked paprika. This seasoning mixture ensures every bite bursts with flavor. Arrange the sprouts cut-side down in a single layer on a baking sheet so they have maximum surface contact with the hot pan, which helps them crisp up beautifully.

Step 2: Roast Until Golden and Crispy

Pop the baking sheet into your preheated oven for about 20 to 25 minutes. Keep an eye out for that telltale crispy, golden-brown color with slightly charred edges. The high heat encourages caramelization, transforming the humble Brussels sprout into a crunchy, sweet, and savory delight. Give the pan a quick shake halfway through if you want more even cooking, but try to keep them flat for the crispiest bottom.

Step 3: Add the Lemon and Parmesan Finish

While the Brussels sprouts are still hot from the oven, drizzle them with fresh lemon juice and melted butter for that extra layer of richness if you opted for it. Now sprinkle on the zesty lemon zest and freshly grated Parmesan cheese, then toss gently but thoroughly to coat every sprout with that vibrant, cheesy brightness. The warmth of the sprouts melts the Parmesan just enough to create a light, crispy coating that’s simply irresistible.

Step 4: Serve and Enjoy

Transfer the beautifully coated Brussels sprouts to a serving bowl and, if you like, add a sprinkle of extra Parmesan or fresh parsley on top for an eye-catching finish. These are best enjoyed immediately while the outside stays crisp and the interior tender, creating the perfect contrast of textures.

Garnishes

A simple sprinkle of more grated Parmesan and bright green chopped parsley adds just the right touch of elegance and color contrast. A light drizzle of extra lemon juice before serving can elevate the flavors even more, making the dish taste fresh and lively. If you’re feeling adventurous, a few red pepper flakes add a bit of heat for those who like spice.

Side Dishes

This dish pairs exceptionally well with hearty mains such as roast chicken, grilled fish, or juicy steaks. For a vegetarian meal, serve alongside creamy risotto or a grain bowl featuring quinoa or farro. The tangy, crispy Brussels sprouts offer a fresh counterpoint to richer or starchier sides, balancing out the meal perfectly.

Creative Ways to Present

For a party or special occasion, consider serving your Crispy Lemon Parmesan Roasted Brussels Sprouts on a large platter with lemon wedges arranged around the edges for guests to squeeze on extra juice. You can also toss in toasted nuts like pine nuts or walnuts to add crunch, or stir in crispy bacon bits for an indulgent twist. Plated individually, a small sprinkle of microgreens on top offers a refined finish that’s sure to impress.

Make Ahead and Storage

Storing Leftovers

If you happen to have leftovers, store them in an airtight container in the refrigerator for up to 3 days. The sprouts will lose some crispiness but still maintain their wonderful flavor and make a great quick lunch or side.

Freezing

For the best texture, freezing is not recommended for this dish because Brussels sprouts tend to lose their crisp after thawing. It’s better to enjoy this recipe fresh, or simply refrigerate and reheat within a few days.

Reheating

To bring back some of the original crispness, reheat the sprouts in a hot skillet over medium heat for a few minutes until warmed through and slightly crisp again. Avoid microwaving as it will make the sprouts soggy.

FAQs

Can I use frozen Brussels sprouts for this recipe?

Fresh Brussels sprouts are best for achieving that crispy texture, but if you use frozen, make sure to thaw and thoroughly pat them dry before roasting to avoid excess moisture. The results won’t be quite as crispy but should still be delicious.

Is there a substitute for Parmesan?

You can use Pecorino Romano or a good quality grated Asiago cheese for a similar salty, nutty flavor. Nutritional yeast is a great vegan alternative that also adds depth and umami.

Can I make this dish vegan?

Absolutely! Skip the Parmesan and butter, then substitute with nutritional yeast and a high-quality olive oil or vegan butter to maintain richness and flavor.

How do I get the Brussels sprouts crispy?

High oven heat, cutting the sprouts in half, and placing them cut-side down on the baking sheet are crucial. Avoid overcrowding the pan so the heat circulates well. Tossing them with enough oil also helps to crisp the edges beautifully.

Can I add other seasonings?

Definitely! You can experiment with things like cumin for warmth, chili powder for some heat, or even a sprinkle of grated ginger for a fresh twist. The key is to complement rather than overpower the lemon and Parmesan.
