Ingredients and Variations
ONIONS: White onions are best for French onion soup as they are not overly sweet like red onions. Yellow onions can be used as well, or a combination of white and yellow tastes great.
BROTH: Beef broth gives French onion soup its classic, full-bodied flavor. A dash of sherry, port, or dry red wine balances out the salty broth and sweet onions with some acid.
SEASONINGS: Fresh thyme has a subtle, herbal flavor and fragrance – use fresh if you can but dried will still work well.
CHEESE: Cheese is what makes French onion soup such a timeless classic dish! Gruyere and Emmentaler have bright and tangy flavors with the perfect “meltability” on sliced bread. Swiss, mozzarella or parmesan cheese works great, too!
EXTRAS: Budget-friendly extras like beans, leftover chicken, frozen meatballs, or ground Italian pork sausage will bulk up French onion soup without it losing its classic savory flavor. If adding meat to bulk up the soup, try mixing in some homemade Italian seasoning mix to intensify the broth.
