Condensed Cream of Mushroom Soup
A classic casserole staple that creates a creamy, savory sauce. You can use cream of chicken or cream of celery as alternatives.
Chow Mein Noodles
These crunchy noodles add texture and a unique twist to the dish. They soften slightly when baked while still providing a crispy bite.
Diced Tomatoes
Brings acidity and freshness, preventing the casserole from being overly heavy.
Soy Sauce
Infuses umami flavor and ties the dish together.
Garlic Powder & Pepper
Simple seasonings that enhance the overall flavor profile.
Tips & Tricks
Drain Excess Grease
After browning the beef, always drain the grease to avoid a heavy, oily casserole.
Layer Evenly
Spread the noodles and beef mixture evenly for consistent baking and flavor in every bite.
Bake Uncovered
This ensures the top gets slightly crispy while the inside stays moist.
Pro Tips
- Add Cheese: For an extra indulgent version, sprinkle shredded cheddar or mozzarella on top before baking.
- Make Ahead: Assemble the casserole up to 24 hours in advance, refrigerate, and bake when ready.
- Use Fresh Herbs: Garnish with fresh parsley or chives for an added burst of flavor and color.
Step-by-Step Instructions
Preheat the Oven
Preheat your oven to 350°F (175°C) to ensure it is ready for baking the casserole.
Cook the Beef and Onion
In a skillet, cook the ground beef and onion over medium heat until the beef is browned. Drain any excess fat to keep the casserole from becoming greasy.
Combine Ingredients
Stir in the cream of mushroom soup, diced tomatoes, water, soy sauce, garlic powder, and pepper. Let the mixture simmer for 5 minutes to blend flavors.
Assemble the Casserole
Grease a 2-quart casserole dish and layer half of the chow mein noodles on the bottom. Spread half of the beef mixture over the noodles. Repeat layers with the remaining noodles and beef mixture.
Bake the Casserole
Bake uncovered for 25–30 minutes, until heated through and slightly crispy on top. Let cool slightly before serving to allow the flavors to meld.
