Ingredients
- 2 lbs beef chuck roast or stew meat, cut into cubes
- 2 tbsp olive oil
- 4 large yellow onions, thinly sliced
- 2 tbsp unsalted butter
- 1 tsp sugar
- 3 garlic cloves, minced
- 1 tbsp Worcestershire sauce
- 1 tbsp all-purpose flour
- 1/2 cup dry white wine (optional)
- 1 1/2 cups beef broth
- 1 tsp fresh thyme (or 1/2 tsp dried)
- Salt and pepper to taste
- 1 1/2 cups shredded Gruyère cheese
- 1 cup shredded mozzarella cheese
- Fresh parsley, chopped (for garnish)
- Optional: croutons or toasted baguette slices
Instructions
- Preheat oven to 375°F (190°C).
- In a Dutch oven or skillet, heat olive oil and brown beef cubes in batches. Set aside.
- In the same pan, melt butter and add onions with sugar. Cook over medium heat, stirring occasionally, for 30-40 minutes until deeply caramelized.
- Add garlic and cook for 1 minute. Pour in wine (if using) to deglaze, scraping up browned bits.
- Stir in flour, then add broth, Worcestershire, thyme, salt, and pepper. Simmer until slightly thickened.
- Mix beef back into the onion mixture. Transfer to a 9×13-inch baking dish.
- Top with Gruyère and mozzarella cheese. Add croutons or baguette slices if desired.
- Bake uncovered for 20-25 minutes until bubbly and golden.
- Let rest 5-10 minutes. Garnish with parsley before serving.
