What is French onion beef casserole?

Think of it as French Onion Soup, but elevated to casserole status. It’s essentially a hearty beef stew, simmered with deeply caramelized onions in a rich, savory broth. The “French Onion” part comes from that incredible onion flavor, achieved by slow-cooking the onions until they’re sweet, golden, and melt-in-your-mouth tender. The casserole element makes it a complete meal, with a base of egg noodles or potatoes, tender beef, and a generous topping of melted Gruyere or Swiss cheese. It’s everything you love about the soup – that comforting warmth, the intense flavor, and the satisfying cheesy pull – but in a substantial, family-friendly format. It’s the perfect dish to bring to a potluck, serve on a cold night, or just enjoy as a comforting weeknight dinner. This French Onion Beef Casserole will be a regular in your rotation!

Why you’ll love this recipe?

Okay, let me tell you why this French Onion Beef Casserole has become a staple in my household. First and foremost, the flavor is absolutely incredible. The combination of the deeply caramelized onions, the savory beef broth, and the tender beef is just a symphony of deliciousness. It’s rich, comforting, and deeply satisfying. Secondly, this is a lifesaver on busy weeknights. It truly is! While the onions do take a little time to caramelize (trust me, it’s worth it!), the rest of the casserole comes together pretty quickly. You can even prep the onions ahead of time to make things even easier. I always do this when I know I’m going to have a busy week. Then you just toss everything together, bake it until bubbly and golden, and dinner is served!

What I love most about this is its cost-efficiency. You can use relatively inexpensive cuts of beef (like chuck roast) because the slow cooking process makes them incredibly tender. Plus, the other ingredients are pantry staples, so you probably already have most of them on hand. This recipe is also incredibly versatile. You can use different types of cheese, add different vegetables, or even swap out the beef for chicken or mushrooms. I’ve even tested this with sweet potatoes and it was even better! The possibilities are endless! I sometimes add a splash of red wine vinegar for a bit of a tang. It is just so good! If you like beef stroganoff, you’ll probably enjoy this French Onion Beef Casserole! It’s a family favorite, budget-friendly, and endlessly adaptable.

How do I make French Onion Beef Casserole?

Quick Overview

Making this French Onion Beef Casserole is easier than you might think! We start by caramelizing the onions – low and slow is the key here! Then, we brown the beef and simmer it in a flavorful broth with the onions. Finally, we layer everything in a casserole dish with egg noodles and top it with lots of cheese before baking it until bubbly and golden. The advantage of this method is how all the flavors meld together during baking, creating a super comforting and deeply satisfying dish. This recipe is a lot easier than making individual bowls of French onion soup, and it’s perfect for feeding a crowd.

Ingredients

For the Main Casserole:
* 2 tablespoons olive oil: Good quality is best, the flavor really shines.
* 2 large onions, thinly sliced: Yellow or sweet onions work great, and even Vidalia onions when they’re in season!
* 2 pounds beef chuck roast, cut into 1-inch cubes: Chuck roast is perfect because it becomes incredibly tender during slow cooking.
* 4 cups beef broth: Use low-sodium broth to control the saltiness of the dish.
* 1 cup dry red wine (optional): Adds depth and richness to the flavor. You can substitute with more beef broth if you prefer.
* 2 tablespoons Worcestershire sauce: For that extra umami kick.
* 1 teaspoon dried thyme: Adds a lovely earthy flavor. Fresh thyme would also be amazing!
* 1/2 teaspoon salt: Adjust to taste.
* 1/4 teaspoon black pepper: Freshly ground is always best!
* 1 pound egg noodles: Wide egg noodles work best in my opinion.
* 2 cups shredded Gruyere cheese: You can also use Swiss cheese or a combination of both.

What are the steps for

Step 1: Caramelize the Onions

Heat the olive oil in a large skillet or Dutch oven over medium-low heat. Add the sliced onions and cook, stirring occasionally, for 30-45 minutes, or until they are deeply golden brown and caramelized. This step is crucial for developing that rich, sweet onion flavor. Be patient and don’t rush the process! I always add a pinch of sugar near the end to help them caramelize even more.

Step 2: Brown the Beef

Remove the caramelized onions from the skillet and set aside. Add the beef cubes to the skillet and brown on all sides. You may need to do this in batches to avoid overcrowding the pan. Browning the beef adds flavor and helps to seal in the juices.

Step 3: Simmer the Beef

Return the caramelized onions to the skillet with the beef. Pour in the beef broth and red wine (if using). Add the Worcestershire sauce, thyme, salt, and pepper. Bring to a simmer, then reduce the heat to low, cover, and cook for 1.5-2 hours, or until the beef is very tender. The longer it simmers, the more flavorful the dish will be!

Step 4: Cook the Egg Noodles

While the beef is simmering, cook the egg noodles according to package directions. Drain well. I always cook them al dente, because they’ll continue to cook in the oven.

Step 5: Assemble the Casserole

Preheat oven to 375°F (190°C). In a large bowl, combine the cooked egg noodles with the beef and onion mixture. Stir well to combine.

Step 6: Add to Casserole Dish

Pour the mixture into a greased 9×13 inch casserole dish. Sprinkle Gruyere cheese evenly over the top.

Step 7: Bake

Is it safe to bake cheese in the preheated oven for 20-25 minutes?

Step 8: Cool & Serve

Let the casserole cool for a few minutes before serving. How do flavors meld together?
