How to Make Roast Beef Noodle Casserole (Step-by-Step Perfection)
Follow these simple steps to bring this sensational Roast Beef Noodle Casserole to life!
- Prep the Oven & Noodles: Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish. If you haven’t already, cook your wide egg noodles according to package directions until al dente. Drain well.
- Combine Wet Ingredients: In a large mixing bowl, whisk together the cream of mushroom soup, milk, sour cream, garlic powder, onion powder, salt, and pepper until smooth and well combined. This forms the luscious, creamy base for our comforting casserole.
- Mix it All Together: Add the cooked egg noodles, shredded roast beef, thawed peas, and 1/2 cup of shredded cheddar cheese to the bowl with the soup mixture. If using, stir in the 1/4 cup of fresh parsley. Gently fold everything together until all ingredients are evenly coated.
- Assemble & Top: Pour the mixture into your prepared baking dish, spreading it out evenly. Sprinkle generously with additional shredded cheddar cheese (about another 1/2 cup or to your liking).
- Bake to Golden Perfection: Bake in the preheated oven for 30-35 minutes, or until the casserole is bubbling around the edges and the cheese on top is melted and lightly golden.
- Rest & Serve: Remove from the oven and let it rest for 5-10 minutes before serving. This helps the casserole set, making it easier to serve. Garnish with crispy fried onions and fresh parsley, if desired. Enjoy your homemade delight!
Fun Twists & Serving Ideas
- Veggie Boost: Add diced carrots, corn, or sautéed mushrooms to the mix for extra flavor and nutrients.
- *Cheese Please: Experiment with different cheeses like Gruyère, Monterey Jack, or a sharp white cheddar for a flavor twist.
- Spice It Up: A pinch of red pepper flakes or a dash of hot sauce in the soup mixture can add a delightful kick.
- Crunch Factor: Besides crispy fried onions, a topping of panko breadcrumbs mixed with melted butter can add a lovely texture.
- Serving Suggestions: This casserole is a meal in itself, but it pairs wonderfully with a simple green salad, steamed green beans, or crusty garlic bread to soak up all that creamy goodness.
