Ingredients You’ll Need
Here’s what you’ll need to make this delicious casserole:
- 1 pound ground beef – The heart of this recipe. Lean ground beef works best, but you can use regular and drain excess fat.
- 1 can (15 oz) green beans, drained – Classic for casseroles. Fresh or frozen can be used too.
- 1 can (10.5 oz) cream of mushroom soup – Adds creaminess and depth of flavor.
- ½ cup milk – Helps thin the soup slightly for a smooth, creamy texture.
- 1 cup shredded cheddar cheese – Melts beautifully and adds sharpness to balance the creamy sauce.
- 1 cup French fried onions – The crispy topping that makes every bite crave-worthy.
- 1 teaspoon garlic powder – Enhances the beef with subtle flavor.
- 1 teaspoon onion powder – Rounds out the flavor and complements the green beans.
- Salt and pepper, to taste – Classic seasoning to bring everything together.
Step-by-Step Instructions
1. Preheat the oven
Start by setting your oven to 350°F (175°C). This gives you time to prep while the oven warms up.
2. Brown the beef
In a large skillet, cook the ground beef over medium heat until browned and no longer pink. Use a spatula to break it apart as it cooks. Drain any excess fat to avoid a greasy casserole.
3. Mix the casserole base
In a large bowl, combine the beef with the drained green beans, cream of mushroom soup, milk, garlic powder, onion powder, salt, and pepper. Stir until everything is well coated and creamy.
4. Assemble
Spoon the mixture into a greased 9×13-inch baking dish, spreading it out evenly.
5. Add cheese
Sprinkle shredded cheddar cheese evenly over the top.
6. Bake
Place the casserole in the oven and bake for 25 minutes, until hot and bubbly. The cheese should be melted and gooey.
7. Top with crispy onions
Remove the casserole, sprinkle the French fried onions over the top, then bake for another 5–10 minutes until the onions are golden and crisp.
