• 1 cup dry red wine (such as Cabernet Sauvignon or Merlot)
• 1 tablespoon Worcestershire sauce

• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• For the Croutons:
• 1 baguette, cut into 1-inch cubes

• Salt and pepper to taste
• For the Cheese Topping:

• 4 ounces Swiss cheese, shredded

Preparing the Beef:

Alright, let’s get started with the heart of our casserole – the beef! This part takes a little time, but trust me, it’s worth it for that tender, flavorful meat.

1. Sear the Beef: In a large Dutch oven or heavy-bottomed pot, heat the olive oil over medium-high heat. Season the beef cubes generously with salt and pepper. Working in batches (don’t overcrowd the pot!), sear the beef on all sides until nicely browned. This usually takes about 2-3 minutes per side. Remove the beef from the pot and set aside.
2. Sauté Aromatics: Add the chopped onion to the pot and cook until softened and translucent, about 5-7 minutes. Add the minced garlic, thyme, rosemary, and pepper, and cook for another minute until fragrant.
3. Bloom the Flour: Sprinkle the flour over the onion mixture and cook for 1-2 minutes, stirring constantly. This helps to thicken the sauce later on.
4. Deglaze and Simmer: Gradually pour in the beef broth, scraping up any browned bits from the bottom of the pot. Stir in the red wine and Worcestershire sauce. Add the bay leaf. Bring the mixture to a simmer.
5. Return Beef and Simmer: Return the seared beef to the pot. Reduce the heat to low, cover the pot, and simmer for at least 2-2.5 hours, or until the beef is very tender and easily shreds with a fork. Stir occasionally to prevent sticking.
6. Shred Beef and Adjust Seasoning: Once the beef is tender, remove it from the pot and shred it with two forks. Return the shredded beef to the pot. Remove the bay leaf. Taste and adjust the seasoning with salt and pepper as needed. If the sauce is too thin, you can simmer it uncovered for a bit to reduce it.

Caramelizing the Onions:

Now for the star of the show – the caramelized onions! This is where the “French Onion” part really shines. Patience is key here; don’t rush the process!

1. Prepare the Onions: Thinly slice the yellow onions. The thinner, the better, as they’ll cook down more evenly.
2. Start the Caramelization: In a large skillet or Dutch oven (if you’ve finished the beef), melt the butter and olive oil over medium-low heat. Add the sliced onions, sugar, salt, and pepper.
3. Cook Low and Slow: Cook the onions, stirring occasionally, for about 45-60 minutes, or until they are a deep golden brown and very soft. The key is to cook them low and slow, allowing the natural sugars to caramelize without burning. Be patient! They will shrink down considerably. If they start to stick or burn, reduce the heat even further and add a tablespoon or two of water to deglaze the pan.

Making the Croutons:

These homemade croutons add a delightful crunch and texture to the casserole. They’re super easy to make, and way better than store-bought!

1. Prepare the Bread: Preheat your oven to 375°F (190°C). Cut the baguette into 1-inch cubes.
2. Season and Bake: In a large bowl, toss the bread cubes with olive oil, garlic powder, dried parsley, salt, and pepper. Spread the bread cubes in a single layer on a baking sheet.
3. Bake Until Golden: Bake for 10-15 minutes, or until the croutons are golden brown and crispy, flipping halfway through. Let them cool slightly before using.

Assembling the Casserole:

Alright, we’re in the home stretch! Time to put everything together and bake this beauty.

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Combine Beef and Onions: In a large bowl, gently combine the shredded beef and the caramelized onions.
3. Layer in Casserole Dish: Pour the beef and onion mixture into a greased 9×13 inch casserole dish.
4. Top with Croutons: Sprinkle the homemade croutons evenly over the beef and onion mixture.
5. Add Cheese: In a separate bowl, combine the shredded Gruyere and Swiss cheeses. Sprinkle the cheese mixture evenly over the croutons.
6. Bake Until Bubbly and Golden: Bake for 20-25 minutes, or until the cheese is melted, bubbly, and golden brown.
7. Let Rest: Let the casserole rest for 5-10 minutes before serving. This allows the flavors to meld together and the cheese to set slightly.

Tips and Variations:

• Wine Choice: Don’t feel like you need to use an expensive wine. A decent Cabernet Sauvignon or Merlot will work perfectly. If you don’t want to use wine, you can substitute with more beef broth.
• Cheese Options: Gruyere and Swiss are classic choices for French Onion soup, but you can also use other cheeses like Provolone, Fontina, or even a little Parmesan.
• Add Vegetables: Feel free to add other vegetables to the beef mixture, such as carrots, celery, or mushrooms. Sauté them along with the onions and garlic.
• Make it Ahead: You can prepare the beef and caramelized onions ahead of time and store them in the refrigerator for up to 2 days. Assemble the casserole just before baking.
• Spice it Up: Add a pinch of red pepper flakes to the beef mixture for a little heat.
• Bread Alternatives: If you don’t have a baguette, you can use other types of bread for the croutons, such as sourdough or Italian bread.
• Broth Quality: Using a high-quality beef broth will significantly enhance the flavor of the casserole. If you have homemade broth, even better!

Serving Suggestions:

This French Onion Beef Casserole is a hearty and satisfying meal on its own. However, you can also serve it with a simple side salad or some crusty bread for dipping into the delicious sauce.
