Make perfect roasted asparagus with crispy, slightly charred tips and tender stalks. Tossed with olive oil, salt, and pepper, this easy side dish finishes with a vibrant squeeze of fresh lemon juice.
Heat the oven to 425 degrees F and line a baking sheet with parchment paper. The hot oven and lined pan help the spears start roasting as soon as they hit the sheet.
Arrange the asparagus on the baking sheet, drizzle with olive oil, season with sea salt and black pepper, and toss to coat before spreading the spears into an even layer. Leave space between the stalks so you hear a gentle sizzle and see browning instead of trapped steam.
Roast for 10 to 15 minutes, then squeeze with lemon juice, adjust the seasoning, and serve right away. The asparagus should look vibrant dark green with lightly crisp tips and stalks that are tender when pierced with a fork.
Notes
Trimming tip: Slice off the bottom 1 to 2 inches where the color dulls and the stems start to feel firm and dry, or bend one spear near the base and let it snap where it naturally breaks.Crispness tip: Pat the asparagus completely dry after washing and leave space between the stalks on the baking sheet so they roast instead of steaming.Reheating: Warm leftovers in a 400 degrees F oven or air fryer in a single layer until the tips crisp up. Avoid the microwave to prevent rubbery texture.Thickness guide: Roast thin spears for 8 to 10 minutes, medium spears for 10 to 15 minutes, and extra-thick spears for up to 20 minutes (peeling the bases of very thick ones helps them cook evenly).Nutrition information is an estimate based on common ingredients and serving sizes.
