Preheat your oven to 220°C (430°F) and line a large baking sheet with parchment paper.
Rinse the broccoli and dry thoroughly, then cut into bite-sized florets. Peel the carrots and slice into thin rounds about 1/4 inch thick.
In a large mixing bowl, toss the prepared vegetables with olive oil, ensuring each piece is coated evenly. Add minced garlic, salt, pepper, or smoked paprika for extra flavor.
Spread the vegetables in a single layer on the prepared baking sheet, making sure they aren’t overcrowded to allow for proper caramelization.
Roast in the oven for about 20 minutes, tossing gently with a spatula after 10 minutes to promote even browning and smoky edges.
Check for doneness: the edges should be dark and crispy, carrots tender when pierced, and broccoli slightly charred. If needed, roast for an additional 5 minutes, watching carefully.
Remove the vegetables from the oven and immediately squeeze fresh lemon juice over them for brightness and flavor balance.
Toss gently to distribute the lemon juice evenly, then sprinkle with chopped fresh herbs for an herbal aroma.
Serve the roasted vegetables warm, enjoying their smoky, caramelized texture and vibrant flavors.
