Onion powder and onion salt has salt added to it. So if you need to watch your sodium count, you may want to think of avoiding these to for health reasons.
ONION Substitute– 1 small fresh chopped onion equals 1 tablespoon instant minced onion or 1/4 cup frozen chopped onion; 1 tablespoon onion powder equals 1 medium-sized fresh onion
Have you thought also of using onion flavored soup mix for onion flavored. Even it has sodium count to watch. But it can add a nice flavor to some recipes.
I order from Penzey's spices...their white powdered onion and the toasted onion powder. Go onto the site and read about it. Both taste great!
Count me in as a Penzy's fan.
Speaking of no salt, they also have many items that are salt free in their salt free section. They also have specials on shipping often if you sign up for their catalogue and emails. Their catalogue is wonderful, with wonderful stories and recipes (just like Taste of Home) :D

Another thought for you....I have used the dried onion flakes on occasion when I've been out of fresh onions. The pieces are so small that they are not easily detected, (have actually snuck them by some "onion haters" on a couple of occasions!) and my opinion is they have better flavor than the powdered onion. I generally use about 1 tablespoon to equal to about 1/4 - 1/3 cup chopped fresh onion.
