Flavorful beef broth without bones? is it possible to make flavorful beef broth as a base for Pho/Soup etc without bones?

I'm not minding the body/gelatinous or not, just the flavor.

on our market here the butchers sell meat scrap gained from bones i'm planning to use that for economic reasons
To have the most flavor, you will need to roast/brown the meat scraps.

Let them get a nice brown color.

you could add aromatic vegetables (onion, carrots, celery) as well to the roasting pan.
