Trim the woody ends from the asparagus about an inch and half.
In a baking sheet or tray, spread asparagus. Lightly coat asparagus with olive oil and season with salt and pepper. I also add garlic powder if I'm not using any sauce.
Bake for 10 minutes. Cover asparagus with foil for the 1st 8 minutes, then remove foil for the remaining 2 minutes to lightly brown asparagus.
Transfer to a serving plate, pour bearnaise sauce or serve it on the side. Enjoy!
Notes
I used thin asparagus. For thicker variety, bake for 15 minutes covered.
