French Onion Beef Casserole Ingredients
Indulge in the deliciousness of French onion beef casserole with these essential ingredients!
For the Casserole
• Dried Egg Noodles – This is the primary carbohydrate; you can substitute with any pasta of a similar shape.
• Lean Ground Beef – The main protein for this dish; ground turkey or chicken can be used for a lighter option.
• Salt and Pepper to Taste – Enhances the overall flavor; adjust according to your preference.
• Condensed Cream of Mushroom Soup (2 cans) – Serves as the creamy base; feel free to swap with cream of chicken or celery soup.
• Lay’s French Onion Dip (1 jar, 15 oz) – Provides flavor and creaminess; you can substitute it with sour cream mixed with onion soup mix for a different taste.
For the Topping
• French’s Fried Onions (1/2 cup) – Adds that delightful crunch on top; crushed potato chips can work too for some extra texture.
• Freshly Chopped Parsley (if desired) – A lovely garnish for freshness; omit if you don’t have any on hand.
Step‑by‑Step Instructions for French Onion Beef Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). Meanwhile, grab a 9×13-inch baking pan and spray it generously with non-stick cooking spray. This will ensure your French Onion Beef Casserole slides out easily once it’s cooked and ready to serve.
Step 2: Cook the Noodles
Cook the dried egg noodles according to the package instructions until they’re al dente, usually around 7-10 minutes. Once cooked, drain the noodles in a colander and set them aside for now. This step allows the noodles to absorb the flavors later while preventing them from becoming mushy in the casserole.
Step 3: Brown the Beef
In a large skillet, heat over medium-high heat and add the lean ground beef. Cook and crumble the beef until it is completely browned and no longer pink, about 6-8 minutes. Season it with salt and pepper to taste, ensuring each piece is well-coated. Drain any excess grease for a lighter dish before moving to the next step.
Step 4: Combine the Creamy Mixture
Stir in the two cans of condensed cream of mushroom soup along with the jar of Lay’s French onion dip into the browned beef. Mix everything together well, allowing the creamy mixture to envelop the beef. This will become the delicious base of your French Onion Beef Casserole, filled with rich flavors.
Step 5: Fold in the Noodles
Gently fold the drained egg noodles into the beef and creamy mixture, ensuring that every noodle is coated evenly. Take care not to break them apart while stirring. This will create a harmonious blend of textures and flavors, making every bite of the casserole delightful.
Step 6: Transfer to Baking Dish
Pour the entire mixture into the prepared baking dish, spreading it out evenly with a spatula. This step is crucial for even cooking, as it ensures all parts of your French Onion Beef Casserole heat through uniformly. Make sure there are no dry spots or unmixed ingredients.
Step 7: Add the Topping
Sprinkle the fried onions over the top of the casserole generously. This crunchy topping will create a delightful contrast to the creamy layers below. If you prefer an alternative crunch, you can also use crushed potato chips, making it a fun twist on a classic dish.
Step 8: Bake to Perfection
Place the baking dish in the preheated oven and bake uncovered for about 20 minutes. Keep an eye on it; the casserole should be heated through and bubbly around the edges when it’s done. The fried onions will turn golden brown, adding a lovely texture to your French Onion Beef Casserole.
Step 9: Serve and Enjoy
Once baked, remove the casserole from the oven and let it rest for a few minutes. This allows the flavors to settle. Scoop out generous portions using a spatula and serve warm, perhaps garnished with freshly chopped parsley for an added touch of freshness.

Make Ahead Options
These French Onion Beef Casseroles are perfect for meal prep, saving you valuable time during busy weeknights! You can prepare the entire casserole up to 24 hours in advance, layering everything in the baking dish without the fried onions. Simply cover it tightly with plastic wrap or aluminum foil and refrigerate until you’re ready to bake. For optimal freshness and taste, avoid adding the crunchy topping until just before serving. When you’re ready to enjoy, preheat your oven and bake the casserole uncovered for about 20 minutes, ensuring it’s heated through and bubbly. This way, you can relish a comforting meal with minimal effort any night of the week!
