1.5 lbs Beef Stew Meat: Cubed beef stew meat is perfect for this recipe, ensuring tender and flavorful results.

2 tbsp Olive Oil: A high-quality olive oil will enhance the flavor of the caramelized onions.
2 cloves Garlic, minced: Adds a pungent and savory depth to the overall flavor profile.
1 cup Beef Broth: Provides moisture and enhances the beef’s flavor during cooking.
1 cup Red Wine: Adds complexity and depth; you can substitute with more beef broth if preferred.
1 tbsp Tomato Paste: Adds a touch of umami and richness.
1 tsp Dried Thyme: A classic herb pairing for beef, adding a subtle earthy note.
1/2 tsp Dried Rosemary: Complements the thyme beautifully, adding another layer of herbal aroma.
Salt and Black Pepper: To season generously and enhance the overall flavor.
1 (10.75 ounce) can Condensed Cream of Mushroom Soup: Creates a creamy, luscious sauce base.
1 cup Shredded Cheddar Cheese: Provides a sharp, tangy flavor and a delightful melt.
1/2 cup Shredded Gruyere Cheese (optional): Adds a nutty, complex flavor and beautiful golden brown topping.

Step-by-Step Instructions

Let’s get cooking! Follow these simple steps to create your delicious French Onion Beef Casserole:

Caramelize the Onions: In a large oven-safe skillet or Dutch oven, heat the olive oil over medium heat. Add the sliced onions and cook, stirring occasionally, for 20-25 minutes, until deeply caramelized and golden brown. Tip: Patience is key here! Low and slow caramelization is the secret to the best flavor.
Brown the Beef: Add the beef cubes to the skillet and brown on all sides. Tip: Don’t overcrowd the pan; work in batches if necessary to ensure proper browning.
Add Flavor: Stir in the minced garlic, tomato paste, thyme, and rosemary. Cook for 1 minute, stirring constantly.
Deglaze the Pan: Pour in the red wine and beef broth, scraping up any browned bits from the bottom of the pan. Tip: This step adds incredible depth of flavor.
Simmer: Bring the mixture to a simmer, then reduce heat to low, cover, and simmer for at least 1 hour, or until the beef is very tender. Tip: If the liquid evaporates too quickly, add a little more broth.
Add the Soup: Stir in the cream of mushroom soup.
Assemble and Bake: Sprinkle the cheddar and Gruyere cheese (if using) over the top. Bake in a preheated oven at 375°F (190°C) for 20-25 minutes, or until the cheese is melted, bubbly, and golden brown.
Rest and Serve: Let the casserole rest for 10 minutes before serving. Enjoy!

Tips for Success

Here are a few tips to ensure your French Onion Beef Casserole turns out perfectly every time:

Don’t rush the onion caramelization; low and slow is key for that deep, rich flavor. Use a good quality olive oil for best results. Ensure your beef is thoroughly browned before adding the other ingredients. Don’t be afraid to season generously with salt and pepper. If you prefer a thicker sauce, simmer the casserole uncovered for the last 15 minutes of cooking. For extra flavor, consider adding a splash of Worcestershire sauce or Dijon mustard. If you don’t have Gruyere, a sharp cheddar or a blend of cheeses will work wonderfully.

Variations to Try

Feel free to experiment with different variations to personalize this recipe:

Spicy Version: Add a pinch of red pepper flakes or a dash of your favorite hot sauce to the mixture.

Mushroom Medley: Add sliced cremini or shiitake mushrooms along with the onions for extra earthy flavor.

Vegetarian Version: Replace the beef with hearty vegetables like potatoes, carrots, and celery. Use vegetable broth instead of beef broth.

Gluten-Free Version: Ensure your cream of mushroom soup is gluten-free. Many brands offer gluten-free versions.

Storing and Reheating

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply microwave individual portions until heated through, or bake in a preheated oven at 350°F (175°C) for 15-20 minutes. Freezing is possible; allow the casserole to cool completely before storing in a freezer-safe container for up to 3 months. To reheat from frozen, thaw overnight in the refrigerator, then reheat as described above. The texture might slightly change upon reheating, but the flavor will remain delicious.
