Ingredients
Meat & Vegetables
- 1 pound Ground Beef
- ½ Onion (Diced)
- 2 cans Cut Green Beans (Drained)
Sauce & Seasonings
- 2 Tablespoon Butter
- ¼ cup Flour
- 1 cup Half & Half
- 1 cup Beef Broth
- ½ teaspoon Garlic Powder
- ½ teaspoon Onion Powder
- ½ teaspoon Black Pepper
- ¾ teaspoon Salt
- ¼ cup Sour Cream
Cheese & Toppings
- ½ cup Shredded Cheddar Cheese
- ½ cup Mozzarella Cheese
- ¾ cup Fried Onion Straws (Optional)
Instructions
- Preheat Oven: Set your oven to 350 degrees Fahrenheit to prepare for baking the casserole.
- Cook Ground Beef: In a Dutch oven or oven-safe skillet, cook the ground beef over medium-high heat until no longer pink, breaking it apart during cooking. Drain any excess fat, then transfer the beef to a bowl and set aside.
- Sauté Onions & Make Roux: In the same pan, melt the butter over medium heat. Add the diced onions and sauté for about 3 minutes until softened. Stir in the flour, cooking and stirring constantly for one minute to form a roux.
- Add Liquids: Gradually whisk in the half & half and beef broth, ensuring there are no lumps. Allow the sauce to simmer for about 7 minutes until it thickens.
- Season the Sauce: Stir in garlic powder, onion powder, black pepper, and salt to combine flavors thoroughly.
- Combine Ingredients: Add the cooked ground beef, drained green beans, and sour cream into the sauce, stirring well to coat everything evenly. If your skillet is not oven-safe, transfer the mixture to a casserole dish.
- Add Cheese Toppings: Sprinkle shredded cheddar and mozzarella cheeses evenly over the top of the casserole mixture.
- Top with Onion Straws: For extra crunch, add a layer of fried onion straws on top (optional).
- Bake: Place the casserole uncovered into the preheated oven and bake for 30 minutes, until the cheese is melted and bubbly.
- Rest & Serve: Let the casserole stand for 5 minutes after baking to set, then serve warm.
Notes
- If you don’t have an oven-safe skillet, use a regular pan for cooking then transfer to a casserole dish before baking.
- Fried onion straws are optional but add great texture to the finished dish.
- You can substitute sour cream with Greek yogurt for a tangier option.
- For a lower-fat version, use lean ground beef and reduced-fat cheeses.
- Ensure to drain canned green beans thoroughly to avoid excess liquid in the casserole.
