Prep Notes:

Measure out your ingredients before starting to keep things organized.

Step-By-Step Instructions

Preheat oven to 350°F (175°C) and grease a 9×13 inch baking dish.
Brown the beef: In a large skillet over medium heat, add your ground beef, breaking it up with a wooden spoon. Cook until fully browned, about 6-8 minutes. Drain any excess fat.
Chef’s Tip: Don’t rush this step; browning the beef properly adds depth to the flavor.
Add aromatics: Stir in the chopped onion and sliced mushrooms to the skillet. Cook for an additional 5 minutes until the onion is translucent and the mushrooms are tender.
Common Mistake Alert: Ensure you don’t skip this step—cooking the onions and mushrooms until soft brings out their natural sweetness.
Mix in the creamy goodness: Stir in the cream of mushroom soup, milk, garlic powder, Worcestershire sauce, salt, and pepper. Mix well until everything is beautifully combined.
Green beans, meet beef: Gently fold in the drained green beans until they are well coated in the creamy mixture.
Transfer and layer: Pour the mixture into the prepared baking dish and spread it evenly.
Top it off: Sprinkle the shredded cheddar cheese generously over the mixture, followed by the crispy fried onions.
Bake it up: Place the casserole in your preheated oven and bake for 25-30 minutes, or until bubbly and the top is golden brown.
Visual Cue: Look for a nice golden crust on top of the cheese and crispy fried onions!
Serve warm: Once out of the oven, allow it to rest for a few minutes before serving.
