Toss asparagus with olive oil, lemon zest, salt, and pepper. Spread on a baking sheet.
Roast for 10-12 minutes, until tender.
Drizzle with lemon juice and serve warm.
Notes
Chef's Tip: Add the lemon juice right at the end, after roasting - cooking it in dulls the bright citrus flavor. Keto Swap: none needed - naturally keto.
