A rich and hearty French onion beef stew that fuses two classic comfort foods—beef stew and French onion soup. Tender beef simmers slowly with caramelized onions, potatoes, and carrots, then gets ladled over toasted bread and topped with melted Gruyère cheese. It’s the perfect blend of rustic comfort and refined French flavor, ideal for both weeknight dinners and slow weekend meals.
Make ahead: Caramelize onions and brown the beef in advance for quicker prep.
Slow cooker option: After searing, cook on low for 7–8 hours, adding veggies in the last 2 hours.
Cheese substitutions: Swiss or Emmental work well if Gruyère is unavailable.
Wine addition: Add ½ cup of dry red wine after tomato paste for extra depth.
Serving tip: For a true French bistro feel, melt cheese-topped bread under the broiler before serving.
