Ingredients
(Scroll to the bottom for the printable recipe card.)
- Asparagus – Choose firm stalks with tight tips. Avoid limp or wrinkled stalks and any with soft or spoiled tips.
- Olive oil – Use olive oil, avocado oil, or melted ghee to coat the spears.
- Fresh garlic – Grated or minced garlic both work. Grating on a microplane makes a paste-like garlic that browns nicely and creates small crispy bits.
- Garlic powder – Optional for extra savory depth.
- Salt + pepper – To taste.
- Fresh lemon juice – A squeeze before serving brightens the dish.
How to clean and prep asparagus
Asparagus is quick to prep. A few simple steps get you ready to roast.
How to trim asparagus
Each asparagus spear has a tougher, woody end that should be removed. There are two common approaches: snapping each spear or trimming with a knife. Trimming all the spears together with a knife is faster and more precise.
Line up the spears on a cutting board and cut where the color changes from pale at the base to deeper green. Discard the woody ends.
How to make oven roasted asparagus
This recipe is fast and simple. Most of the time is hands-off in the oven—plan on 10–15 minutes of roasting time depending on spear thickness.
Step-by-step:
- Preheat oven to 425°F (220°C).
- Wash, dry, and trim the woody ends from the asparagus.
- Arrange the asparagus on a large baking sheet in a single layer.
- In a small bowl combine olive oil, finely chopped or grated garlic, garlic powder (if using), salt, and black pepper.
- Drizzle the mixture over the asparagus and toss to coat evenly. Spread the spears out so they do not overlap.
- Roast for 10–15 minutes, until the asparagus is bright green and tender, with slightly caramelized tips.
- Finish with a squeeze of fresh lemon juice and additional salt if needed, then serve immediately.
How long does asparagus take to cook in the oven
Cooking time varies with thickness. Thin spears can finish in 8–10 minutes, while medium-thick spears typically take about 12 minutes at 425°F. Very thick spears may need closer to 15 minutes.
How do you know when asparagus is done?
Asparagus is done when it’s tender yet still bright green and the tips are slightly caramelized. Test doneness by piercing the thick part of a stalk with a paring knife — it should slide in with little resistance.
How long does asparagus last?
Fresh: Stored properly in the refrigerator, fresh asparagus keeps about 4 days to one week depending on how fresh it was at purchase.
Cooked: Leftover roasted asparagus is best eaten within one to two days for optimal flavor and texture.
