We love soup all year long, but right now is the perfect time for this Perfect French Onion Soup! Warm and comforting, and totally doable on a weeknight, this soup served with a small side salad will make your dinner and your family will request more!
Such a simple dish, French Onion Soup. Most recipes end up tasting like burnt onion tea with a cheese topping. Not this one! I recommend using only yellow onions for the classic bistro soup.But you can blend them up for a taste that’s a bit different. (Texas sweets are my favorite or Vidalia’s in season, mix in with the yellows and a red) . I usually use which ever stock I happen to have on hand. A homemade beef or chicken broth gives such a complex and different taste, but when it comes to easy you can’t beat the store bought varieties. If you wanted to make this totally vegetarian, substitute a veggie broth. See, simple and easy.
