There’s something irresistibly comforting about a warm, hearty soup on a cold day, and French onion soup is the ultimate cozy choice. Caramelized onions, rich broth, toasted bread, and melted cheese combine into a simple yet deeply satisfying dish.
Originating from ancient Rome and introduced in the United States in 1861 by New York restaurateur Henri Mouquin, French onion soup has become a beloved classic. I sampled this dish at four well-known chains to find the best version for your enjoyment.
Panera Bread
Nutrition (per bowl): Calories 290 | Fat 12 g (Saturated 6 g) | Sodium 1,990 mg | Carbs 33 g (Fiber 3 g, Sugar 16 g) | Protein 10 g
Panera’s Bistro French Onion Soup, priced at $6.69, comes with a side of French baguette.
Appearance: Aside from a few croutons, there was barely any cheese. A small amount of grated Asiago had settled at the bottom, and the onions were lightly colored rather than deeply caramelized.
Flavor: The soup was sweet but not in an onion-forward way. The broth, enhanced with sherry wine vinegar gastrique, reminded me more of a light vegetable soup than a French onion. Black pepper and sea salt were hardly noticeable. Overall, it felt minimalist—underwhelming and lacking depth.
Outback Steakhouse
Nutrition (per bowl): Calories 570 | Fat 36 g (Saturated 18 g) | Sodium 4,120 mg | Carbs 42 g (Fiber 4 g, Sugar 18 g) | Protein 19 g
Outback’s French onion soup, priced at $7.99, is a fan favorite with many online copycat recipes.
Appearance: Topped with a Holland rusk covered in melted Gruyère and sprinkled with parsley, the soup looked visually impressive. The broth was dark and rich, with the onions well-cooked.
Flavor: The soup was flavorful but very salty. The cheese-topped bread required a knife to cut, which made it a little messy. The broth was smooth and the caramelized onions generous. Overall, it was hearty and satisfying, though slightly tricky to eat.
Applebee’s
Nutrition (per bowl): Calories 370 | Fat 21 g (Saturated 13 g) | Sodium 1,250 mg | Carbs 26 g (Fiber 2 g, Sugar 9 g) | Protein 16 g
Applebee’s French onion soup, priced at $3.99, is a surprisingly good option.
Appearance: The bowl arrived with a golden-brown cheesy top, slightly overflowing, reminiscent of a crème brûlée crust. The broth was light, and bread floated just below the surface.
Flavor: Light but flavorful, complemented by a mix of Swiss and Parmesan cheese. The combination was unexpected and delicious, with a rich, buttery taste that invited more slurping.
LongHorn Steakhouse
Nutrition (per bowl): Calories 480 | Fat 31 g (Saturated 18 g) | Sodium 1,830 mg | Carbs 20 g (Fiber 0 g, Sugar 7 g) | Protein 30 g
LongHorn’s French onion soup, priced at $6.39, is renowned for its generous cheese and rich flavor.
Appearance: A thick, toasted “hat” of Parmesan and garlic crust covers a blend of Swiss and provolone cheeses. Beneath floats a crostini in dark, flavorful broth with well-caramelized onions.
Flavor: This was the overall winner. The combination of velvety cheese, savory broth, and perfectly caramelized onions created a gooey, indulgent experience. The use of sirloin beef stock enhanced the depth of flavor, and the cheese melted perfectly without being chewy.
No need to travel to Paris for a French onion fix—these chain restaurants offer satisfying options that can bring this classic comfort dish closer to home.
