I made onion soup tonight.
Not that, but the old style cream of onion soup, and it came out well, if I say so myself.
6 to 8 medium potatoes (used Russet Burbank Idahos, for that is what I have.) in chicken broth (Better Than Boullion brand). Cook, covered until very tender. (6 quart Farberware dutch oven.)
Meanwhile, peel and slice 2 pounds more or less (a generous amount, anyway-) of standard brown/yellow onions. In separate fry pan, melt a nice glob of REAL butter, and when it is melted and hot, add the onions. Lower the heat, and stir every 10 or 15 minutes, or so. Onions should be nicely browned on at least one side, and very tender.
When potatoes are very soft, taste the broth, and cook it down separately, if necessary.
Add onions to potatoes and broth. Puree with stick blender.
