Ingredients

• 1 lb ground beef

• 1 tablespoon olive oil

• 1 small onion, finely chopped

• 2 cloves garlic, minced

• 1/2 teaspoon salt

• 1/2 teaspoon black pepper

• 1/2 teaspoon onion powder

• 1/2 teaspoon paprika (optional)

• 1 can (10.5 oz) cream of mushroom soup

• 1/2 cup sour cream

• 1/4 cup milk

• 3 cups cooked or canned green beans (drained if canned)

• 2 cups frozen hash brown potatoes or diced cooked potatoes

• 1 1/2 cups shredded cheddar cheese

• 1 cup crispy fried onions (divided)

Instructions

1. Preheat the oven.
   Set your oven to 350°F (175°C). Grease a 9×13-inch casserole dish and set it aside.

2. Cook the beef.
   Heat olive oil in a large skillet over medium heat. Add the ground beef and chopped onion. Cook until the beef is browned and the onions are soft, about 6–8 minutes.
   Stir in the garlic, salt, pepper, onion powder, and paprika. Cook for another minute until fragrant. Drain any excess grease if needed.

3. Make the creamy sauce.
   In a large bowl, whisk together the cream of mushroom soup, sour cream, and milk until smooth and creamy.

4. Assemble the casserole.
   Add the cooked beef mixture, green beans, potatoes, and 1/2 cup of the shredded cheddar to the sauce. Stir gently until everything is evenly coated.

5. Transfer and top.
   Pour the mixture into your prepared casserole dish and spread it out evenly. Sprinkle the remaining cheese on top, followed by 1/2 cup of the crispy fried onions.

6. Bake until bubbly.
   Bake uncovered for 30 minutes. Then sprinkle the remaining fried onions over the top and return to the oven for 5–10 minutes, until golden, crispy, and bubbling around the edges.

7. Rest and serve.
   Let the casserole cool for a few minutes before serving so it sets up nicely.

Presentation

• Sprinkle a few extra crispy onions on top right before serving for extra crunch.

• A simple green salad or warm dinner rolls on the side balance the richness beautifully.
