Ingredients for Hamburger Green Bean Casserole

Here’s what you’ll need for the recipe:

• 1 lb ground beef: Choose lean for less grease or regular for richer flavor.
• 1/2 onion, diced: Adds a mild sweetness.
• 2 cloves garlic, minced: Brings aromatic depth.
• 1 tsp Worcestershire sauce: For that classic, smoky umami punch.
• Salt & pepper to taste.
• 2 cups cooked green beans (fresh, canned, or frozen).
• 1 can (10.5 oz) cream of mushroom soup.
• 1/2 cup sour cream.
• 1 1/2 cups shredded cheddar cheese.
• 1/2 cup shredded mozzarella.
• 1 cup crispy fried onions.

Substitutions

• Swap ground beef for ground turkey or chicken for a leaner option.
• Use Greek yogurt instead of sour cream for extra protein.
• Try French’s green beans for an even simpler shortcut.

Step-by-Step Cooking Instructions

Step 1: Cook the beef

Heat a skillet over medium heat. Brown the ground beef with the diced onion and minced garlic. Once fully cooked, drain off excess grease. Stir in Worcestershire sauce, salt, and pepper for seasoning.

Step 2: Mix the sauce

Combine the cream of mushroom soup and sour cream in a mixing bowl. Stir until smooth and well blended.

Step 3: Assemble the casserole

Grease a 9×13-inch baking dish. Begin layering the ingredients:

1. Ground beef mixture.
2. Cooked green beans.
3. Creamy soup mixture.
4. A layer of shredded cheddar and mozzarella cheeses.

Repeat layers if desired.

Step 4: Add the crispy onions

Top the assembled casserole with crispy fried onions for that irresistible crunch.

Step 5: Bake

Preheat your oven to 350°F (175°C). Bake the casserole for 25–30 minutes, or until it’s bubbly and the cheese is melted with golden edges.

Step 6: Serve and enjoy!

Allow the casserole to cool slightly before slicing into portions. Serve warm and enjoy that cheesy, gooey bite!

Health Benefits of This Hearty Dish

While Hamburger Green Bean Casserole is indulgent, it also offers some nutritional perks:

• Protein-packed with lean ground beef or turkey, keeping you full longer.
• Rich in fiber from green beans, supporting digestion.
• Calcium boost from the cheese, contributing to strong bones.

To make it even healthier, consider low-fat sour cream and reduced-fat cheese!

Serving Suggestions

Pair this comforting casserole with:

• A fresh green salad for balance.
• Warm dinner rolls or crusty bread to soak up every cheesy bite.
• A light, crisp white wine like Sauvignon Blanc.

Recipe Variations to Try

Make this casserole your own with these creative tweaks:

• Spicy Twist: Add diced jalapeños or a dash of cayenne to the beef mixture.
• Extra Veggies: Mix in corn, mushrooms, or diced red bell peppers.
• Keto Friendly: Swap the cream of mushroom soup for heavy cream and skip the crispy onions.

Pro Tips for Perfecting Your Casserole

• Don’t Overcook the Green Beans: Keep them tender-crisp for a satisfying texture.
• Layer for Balance: Even layers ensure every bite has beef, beans, and cheesy goodness.
• Broil for Golden Perfection: After baking, broil for 2–3 minutes to crisp up the onion topping.

Storing and Reheating Your Casserole

Storage:

• Refrigerate in an airtight container for up to 3 days.
• Freeze for up to 3 months (store without the crispy onions to keep them crunchy).

Reheating:

• Microwave individual portions for 2–3 minutes, or until heated through.
• Reheat in the oven at 350°F for 10–15 minutes for best results.

Common Mistakes to Avoid

1. Skipping the Drain: Always drain grease from the beef to avoid a soggy casserole.
2. Overloading Toppings: Too many crispy onions can overpower the dish. Keep it balanced.
3. Using Unseasoned Meat: Don’t forget the Worcestershire sauce, salt, and pepper for flavor!
