Preheat your oven to 200°C (400°F) and line a baking sheet with parchment paper or a silicone mat for easy cleanup.
Peel the carrots if you prefer, then cut them into uniform sticks or rounds about half an inch thick to promote even roasting.
In a small saucepan, melt the butter over medium-low heat, then add the minced garlic and cook gently until fragrant and just starting to turn golden, about 1 minute—your kitchen will fill with that warm, savory aroma.
Pour the garlic butter into a mixing bowl, then toss the prepared carrots in the mixture until they are evenly coated, ensuring every piece is infused with rich garlic flavor.
Season generously with salt and freshly ground black pepper, and add chopped herbs or lemon zest if using, to enhance the flavor profile.
Spread the coated carrots in a single layer on your prepared baking sheet, making sure they are not crowded to allow proper caramelization.
If desired, drizzle a teaspoon of olive oil over the carrots for extra crispiness and toss gently to distribute evenly.
Roast the carrots in the oven for about 25 to 30 minutes, tossing once halfway through, until they are tender inside and caramelized at the edges, filling your kitchen with a sweet, garlic scent.
Check for doneness by piercing a carrot with a fork; it should glide in easily, and the edges should be crispy and browned.
Remove the carrots from the oven and let them rest for 5 minutes—this helps their flavors settle and slightly enhances their texture.
Finish by sprinkling with additional lemon zest or herbs if desired, then serve warm, letting the natural sweetness and rich garlic aroma shine through.
