How to Make French Onion Beef and Pasta Casserole
Step 1: Caramelize the Onions
Preheat your oven to 350°F (175°C).
Heat the olive oil in a large skillet over medium heat.
Add the sliced onions and cook for 10–12 minutes, stirring occasionally, until they become soft, deeply golden, and caramelized.
Step 2: Add the Garlic
Stir in the minced garlic and cook for 1–2 minutes, just until fragrant.
Step 3: Cook the Egg Noodles
Meanwhile, cook the egg noodles according to the package directions until al dente.
Drain and set aside.
Step 4: Brown the Beef
Add the ground beef to the skillet with the onions.
Cook until browned, breaking it apart as it cooks.
Drain any excess grease if necessary.
Step 5: Make the Creamy Sauce
Pour in the beef broth and heavy cream.
Add the dried thyme, salt, and black pepper.
Bring the mixture to a gentle simmer and cook for about 5 minutes, allowing the flavors to blend.
Step 6: Combine Everything
Fold the cooked egg noodles into the beef mixture, stirring until everything is evenly coated with the creamy sauce.
Step 7: Assemble the Casserole
Transfer the mixture to a greased 9×13-inch baking dish.
Sprinkle the shredded Swiss cheese evenly over the top.
Step 8: Bake
Bake for 25–30 minutes, or until the cheese is melted, bubbly, and lightly golden.
Allow the casserole to rest for about 5 minutes before serving.
Step 9: Garnish
Sprinkle with freshly chopped parsley and serve warm.
