How to Make Lemon Parmesan Roasted Brussels Sprouts with Thyme and Red Pepper Flakes Recipe
Step 1: Preparing and Roasting the Brussels Sprouts
Begin by preheating your oven to 425°F and lining a baking sheet with parchment paper for easy cleanup. Trim and halve the Brussels sprouts so they roast evenly and develop those irresistible golden edges. Toss them gently with a generous drizzle of extra-virgin olive oil, then season with sea salt and freshly ground black pepper. Spread them out in a single layer on your baking sheet to ensure even roasting. Pop them in the oven for 20 to 30 minutes, depending on the size of your sprouts, until they’re tender and beautifully caramelized around the edges.
Step 2: Adding the Brightness and Flavor Boost
Once the Brussels sprouts are roasted to perfection, it’s time to elevate their flavor. Transfer them to a bowl and freshly squeeze in the lemon juice, adding the zest for an extra lemon punch. Sprinkle on the grated Parmesan and scatter fresh thyme leaves over the sprouts. Toss everything gently but thoroughly so each piece is coated with the zesty, cheesy mixture that makes this Lemon Parmesan Roasted Brussels Sprouts with Thyme and Red Pepper Flakes Recipe so wonderfully unforgettable.
Step 3: Garnishing for the Final Touch
To finish the dish, sprinkle a pinch of red pepper flakes evenly across the Brussels sprouts for a subtle kick of heat. A handful of fresh parsley leaves adds a bright, herbaceous contrast and lovely color that makes the dish as pretty as it is delicious.

Garnishes
Beyond the parsley and red pepper flakes, feel free to experiment with toasted pine nuts or a sprinkle of lemon zest right before serving to amp up texture and aroma. A light drizzle of good quality balsamic glaze can also bring a delightful sweet-tart layer that plays well against the Parmesan and heat.
Side Dishes
This dish pairs beautifully with roasted meats like a juicy herb-roasted chicken or pan-seared salmon, as well as hearty grain bowls featuring quinoa or farro. It can also shine alongside creamy mashed potatoes or buttered egg noodles to balance the spice and acidity perfectly.
Creative Ways to Present
Serve the roasted sprouts as a vibrant salad base by adding toasted almonds and dried cranberries for chewiness and crunch. For a modern twist, pile them on toasted baguette slices with extra Parmesan and a drizzle of lemon-infused olive oil – a fancy finger food everyone will love at your next gathering.
Make Ahead and Storage
Storing Leftovers
If you find yourself with leftovers (or want to prepare in advance), store the roasted Brussels sprouts in an airtight container in the refrigerator for up to 3 days. Be sure to add the lemon juice, Parmesan, thyme, and red pepper flakes fresh just before serving to keep those flavors bright and fresh.
Freezing
While roasting Brussels sprouts from frozen isn’t ideal, you can freeze cooked Brussels sprouts for up to 2 months. Spread them on a baking sheet to freeze individually first, then transfer to a freezer-safe bag. To maintain the best texture, it’s recommended to reheat them in an oven or skillet rather than a microwave.
Reheating
Bring back the crunch by reheating the sprouts in a hot oven set to 400°F for about 8-10 minutes. Stir halfway through to avoid drying out, and reapply a dash of olive oil if needed. Avoid microwaving whenever possible since it can make the sprouts soggy.
FAQs
Can I use frozen Brussels sprouts for this recipe?
Fresh Brussels sprouts are best for roasting because they hold their texture and caramelize beautifully. Frozen sprouts tend to release more water, leading to steaming rather than roasting. If you use frozen, make sure to thaw and pat dry completely before roasting.
How spicy are the red pepper flakes in this recipe?
The pinch of red pepper flakes adds just a gentle warmth that complements the earthiness of the sprouts and the brightness of the lemon, not an overwhelming heat. You can adjust the amount to suit your spice preference.
Can I make this recipe vegan?
Absolutely! Simply omit the Parmesan cheese or swap it for a vegan cheese alternative or nutritional yeast. This still keeps the savory umami notes and pairs well with the lemon and thyme flavors.
Is this dish suitable for meal prepping?
Yes, roasted Brussels sprouts hold up well for a couple of days refrigerated. Just store the components separately if possible and combine them when ready to serve to preserve freshness.
What’s the best way to get Brussels sprouts crispy?
Start with high heat roasting at 425°F, make sure the sprouts are dry before tossing with oil, and spread them out in a single layer. Avoid overcrowding the pan to ensure each sprout has room to crisp up nicely.
