Step-by-Step Cooking Instructions

Now that you have your ingredients ready, let’s get into the cooking process. This French Onion Beef Casserole recipe is straightforward, but the key to its rich flavor is taking the time to properly caramelize the onions.

Step 1: Preheat the Oven

Begin by preheating your oven to 350°F (175°C). Grease a 9x13-inch casserole dish with non-stick spray or butter and set aside.

Step 2: Cook the Egg Noodles

Cook the egg noodles according to the package instructions. Drain and set aside.

Step 3: Caramelize the Onions

In a large skillet, heat 2 tablespoons of olive oil over medium-low heat. Add the thinly sliced onions and cook slowly for about 20-25 minutes, stirring occasionally, until the onions are golden brown and caramelized. Be patient—this step is crucial for getting that deep, sweet onion flavor. Add the minced garlic during the last few minutes of cooking and sauté until fragrant.

Step 4: Cook the Ground Beef

In another large skillet, cook the ground beef over medium heat until it is browned and fully cooked. Drain any excess fat. Stir in the Worcestershire sauce, thyme, salt, and pepper. Remove from heat and set aside.

Step 5: Make the Beef Mixture

In a large mixing bowl, combine the cooked ground beef with the caramelized onions, sour cream, and half of the shredded cheeses (both mozzarella and Gruyère). Mix everything together until well combined.

Step 6: Assemble the Casserole

Spread the cooked egg noodles evenly in the prepared casserole dish. Pour the beef mixture over the noodles and spread it out evenly. Top with the remaining shredded cheeses and sprinkle the French-fried onions over the top for added crunch.

Step 7: Bake the Casserole

Place the casserole dish in the preheated oven and bake for 25-30 minutes, or until the cheese is bubbly and golden brown. The French-fried onions should be crispy and lightly browned.

Step 8: Cool and Serve

Remove the casserole from the oven and let it cool for 5-10 minutes before serving. This will help the flavors meld together and make it easier to slice and serve.
