Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

• 1.5 lbs beef chuck roast, cut into chunks
• 1 tablespoon olive oil
• 3 large yellow onions, thinly sliced
• 3 cloves garlic, minced
• 1 tablespoon balsamic vinegar
• 1 tablespoon tomato paste
• 4 cups beef broth
• 1/2 cup dry white wine (optional)
• 1 teaspoon dried thyme
• 1 teaspoon dried rosemary
• Salt and black pepper to taste
• 1 cup shredded Gruyère or Swiss cheese
• Fresh parsley, chopped (for garnish)
• 6 slices of French bread or baguette

Directions

1. Heat olive oil in a large pot over medium heat. Add beef chunks, season with salt and pepper, and brown on all sides. Remove and set aside.
2. In the same pot, add sliced onions. Cook for 25–30 minutes, stirring occasionally, until deeply caramelized.
3. Stir in garlic, tomato paste, and balsamic vinegar. Cook for 2–3 minutes more.
4. Return the beef to the pot. Add broth, wine (if using), thyme, and rosemary. Stir to combine.
5. Bring to a boil, then reduce heat to low. Cover and simmer for 2 to 2.5 hours, or until beef is tender and stew is rich and thick.
6. Toast the French bread slices until golden.
7. Ladle the stew into bowls, sprinkle cheese on top, and place toasted bread on the side or partially dipped in.
8. Garnish with chopped parsley and serve hot.

Variations

• Slow cooker method: After browning the beef and caramelizing the onions, transfer everything to a slow cooker and cook on low for 6–8 hours.
• Cheesy topping alternative: Broil bowls of stew with cheese-topped bread directly in them for a gratin-style finish.
• Red wine substitute: Use red wine instead of white for a bolder, deeper flavor.
• Add vegetables: Include carrots, mushrooms, or parsnips for a more traditional stew feel.
• Gluten-free option: Use gluten-free bread and ensure your broth is certified gluten-free.

Storage/Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, warm gently in a pot over low heat until heated through. You may need to add a splash of broth or water to loosen the consistency. Bread and cheese are best added fresh when serving leftovers.

FAQs

Can I make this stew in advance?

Yes, this stew tastes even better the next day. Prepare ahead and store in the fridge; reheat gently when ready to serve.

What’s the best cut of beef to use?

Beef chuck roast is ideal for stews due to its marbling and tenderness after long cooking.

Do I have to use wine?

No, the wine is optional. You can omit it or substitute it with more beef broth or a bit of Worcestershire sauce.

Can I freeze this stew?

Yes, freeze the stew (without bread or cheese) in a sealed container for up to 3 months. Thaw overnight and reheat gently.

How do I get the onions perfectly caramelized?

Cook them low and slow, stirring occasionally. The process takes about 25–30 minutes and results in deeply sweet, golden onions.

Can I use pre-cooked beef?

It’s not recommended, as raw beef that’s browned and slow-cooked will absorb the flavors better and yield a more tender result.

What’s a good substitute for Gruyère cheese?

Swiss cheese, provolone, or even mozzarella can work as alternatives, though flavor and meltability may vary slightly.

Is it possible to make this dish vegetarian?

You can replace the beef with mushrooms and use vegetable broth, but the result will be more of a French onion soup than a stew.

Can I use store-bought French onion soup?

It’s not recommended, as the flavor won’t be as deep and balanced as homemade caramelized onions and fresh broth.

What type of bread works best?

A crusty French baguette or artisan loaf is ideal for soaking up the rich broth without falling apart.

Slow-Cooked French Onion Beef Stew is a warm, deeply satisfying dish that brings together the richness of caramelized onions and the heartiness of tender beef in one comforting bowl.
