French Onion Beef Casserole Ingredients • Here’s everything you need for a delicious French Onion Beef Casserole that will warm your heart and satisfy your cravings! For the Casserole Dried Egg Noodles – Provide the main structure and heartiness; you can substitute with whole wheat noodles for added nutrition. Lean Ground Beef – The main protein source that adds richness; consider swapping with ground turkey or a meat alternative for a lighter dish. Condensed Cream of Mushroom Soup – This adds delightful creaminess and depth of flavor; cream of chicken soup is a great alternative for a different taste. Lay’s French Onion Dip – Contributes a strong onion flavor and creaminess; a mixture of sour cream with onion soup can serve as a substitute if needed. French’s Fried Onions – Adds a crunchy topping and enhances the overall onion flavor; crushed potato chips can be an exciting alternative for that crunch. Salt and Pepper – Essential for enhancing the dish’s flavor; adjust to your taste as needed. For the Garnish Freshly Chopped Parsley – An optional garnish that gives a pop of color and freshness to the creamy casserole. Step‑by‑Step Instructions for French Onion Beef Casserole Step 1: Preheat and Prepare Begin by preheating your oven to 350°F (175°C). While the oven warms up, lightly spray a 9×13-inch baking pan with non-stick cooking spray to ensure the casserole doesn’t stick during baking. This will prepare the perfect home for your mouthwatering French Onion Beef Casserole! Step 2: Cook the Noodles In a large pot, bring water to a boil and add the dried egg noodles. Cook according to the package directions until al dente, typically around 5–7 minutes. Once cooked, drain the noodles in a colander and set them aside, allowing them to cool and firm slightly while you work on the beef mixture. Step 3: Brown the Beef In a large skillet over medium-high heat, add the lean ground beef. Use a wooden spoon to break it apart as it cooks, stirring occasionally for about 6–8 minutes until it’s fully browned and no longer pink. Season your beef with salt and pepper for added flavor, then drain any excess grease to keep your casserole from becoming greasy. Step 4: Mix in the Soups Once the beef is browned, reduce the heat to medium and stir in the condensed cream of mushroom soup along with the Lay’s French Onion Dip. Mix thoroughly until all the ingredients are well-combined and creamy, creating a delicious base for your French Onion Beef Casserole that oozes flavor. Step 5: Combine Noodles and Beef Mixture Gently fold the drained egg noodles into the beef mixture in the skillet using a spatula. Ensure that every noodle is evenly coated with the creamy sauce and the meaty goodness. This step is essential for achieving that delightful harmony of flavors and textures in your casserole. Step 6: Prepare for Baking Pour the entire noodle and beef mixture into your prepared baking pan, spreading it out evenly. To finish off, generously sprinkle the French’s Fried Onions on top of the casserole. This will create a crispy, golden layer that adds both crunch and flavor when baked. Step 7: Bake to Perfection Place the baking pan in the preheated oven and bake uncovered for about 20 minutes. You’ll know it’s ready when the casserole is heated through and bubbly, with the fried onions on top turning a beautiful golden brown. This is when your cozy French Onion Beef Casserole transforms into a comforting delight! Step 8: Serve Warm Once baked, remove the casserole from the oven and let it cool for a few minutes. Serve warm, optionally garnished with freshly chopped parsley for a touch of brightness. Enjoy the comforting and flavorful essence of your homemade French Onion Beef Casserole with your loved ones!
