Preheat your oven to 220°C (430°F). Line a baking sheet with parchment paper to keep things easy for cleanup.
Peel the carrots if you like, then cut them into uniform 1-inch pieces. This helps them cook evenly and caramelize nicely.
Trim the woody ends off the asparagus and cut the stalks to about 4-5 inches, keeping the thinner spears whole for crispness.
In a large mixing bowl, toss the carrots and asparagus with 2 tablespoons of olive oil until everything is evenly coated. This will help them caramelize and develop flavor.
Spread the vegetables out in a single layer on the prepared baking sheet, making sure they’re not crowded so they roast evenly and get crispy at the edges.
Roast in the oven for about 20-25 minutes, flipping the vegetables with tongs or spatula halfway through. You’re looking for deep golden edges and tender insides.
Once done, remove the tray from the oven and transfer the roasted vegetables to a serving bowl. Squeeze fresh lemon juice over the hot veggies for a bright, fresh finish.
Toss gently to coat everything evenly with the lemon juice, then let rest for a couple of minutes to allow flavors to settle.
Serve immediately while the vegetables are warm, smoky, and vibrant, with a hint of brightness from the lemon.
