Description
A creamy, comforting one-pan casserole made with ground beef, green beans, cheese, and a savory mushroom sauce, all topped with crispy fried onions. Perfect for family dinners or potlucks.
Ingredients
- 1 pound ground beef
- 1 small yellow onion, diced
- 2 cloves garlic, minced (optional)
- 3 cans (14.5 oz each) cut green beans, drained
- 1 can (10.5 oz) cream of mushroom soup
- 1/2 cup sour cream
- 1/2 cup whole milk
- 1 teaspoon Worcestershire sauce
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon ground black pepper
- 1/2 teaspoon salt (adjust to taste)
- 1 1/2 cups shredded cheddar cheese (or Colby Jack)
- 1 cup crispy fried onions
- Butter or cooking spray, for greasing dish
Instructions
- Preheat oven to 350°F (175°C) and grease a 9×13-inch baking dish with butter or cooking spray.
- In a large skillet over medium heat, cook ground beef and diced onion. Add garlic if using. Cook until beef is browned and onion is soft. Drain excess grease.
- In a mixing bowl, whisk together cream of mushroom soup, sour cream, milk, Worcestershire sauce, garlic powder, onion powder, salt, and pepper until smooth.
- Add the cooked beef mixture, drained green beans, and 1 cup of shredded cheese to the sauce. Stir to combine evenly.
- Transfer the mixture to the prepared baking dish and spread evenly. Top with remaining 1/2 cup of cheese and crispy fried onions.
- Bake uncovered for 25–30 minutes, or until bubbly and golden. If you want extra crispy onions, add them during the last 5–10 minutes of baking.
Notes
- Use fresh or frozen green beans if preferred—just blanch before using.
- Swap cream of mushroom soup with cream of chicken or celery for variety.
- Add jalapeños or chili flakes to make it spicy.
- Top with crackers or breadcrumbs instead of fried onions for a lighter option.
- Can be made ahead and baked later.
