Ingredients Breakdown & Why They Matter

Ground Beef

1 pound ground beef
Forms the hearty base of the casserole. Browning it first builds flavor and removes excess fat.

Tip: 80/20 ground beef works best for flavor.

Green Beans

1 can (15 oz) green beans, drained
Adds texture and balances the richness of the beef and sauce.

Swap options: Fresh blanched or frozen green beans work too.

Cream of Mushroom Soup

1 can (10.5 oz)
Creates the creamy backbone of the dish and ties everything together.

Alternative: Cream of chicken or cream of celery soup.

Milk

½ cup milk
Thins the soup slightly, making the casserole creamy instead of dense.

Cheddar Cheese

1 cup shredded cheddar cheese
Adds sharpness, richness, and that irresistible cheesy pull.

French Fried Onions

1 cup
The signature crunchy topping that takes this casserole over the top.

Seasonings

• 1 tsp garlic powder
• 1 tsp onion powder
• Salt & pepper to taste

These simple seasonings boost flavor without overpowering the dish.

Step-by-Step Directions (With Pro Tips)

1️⃣ Preheat the Oven

Preheat to 350°F (175°C). Lightly grease a 9×13-inch baking dish.

2️⃣ Brown the Ground Beef

In a large skillet over medium heat, cook the ground beef until fully browned, breaking it apart as it cooks. Drain excess fat.

Why this matters:
Removing excess grease keeps the casserole rich—but not oily.

3️⃣ Mix the Casserole Base

In a large bowl, combine:

• Cooked ground beef
• Drained green beans
• Cream of mushroom soup
• Milk
• Garlic powder
• Onion powder
• Salt and pepper

Mix until evenly combined.

4️⃣ Assemble

Transfer the mixture to the prepared baking dish and spread evenly.

5️⃣ Add Cheese

Sprinkle shredded cheddar cheese evenly over the top.

6️⃣ Bake

Bake uncovered for 25 minutes, until hot and bubbly and cheese is melted.

7️⃣ Add the Crunch

Remove from the oven, sprinkle French fried onions over the top, then return to the oven for 5–10 minutes, until golden brown.

Texture & Eating Experience

This casserole is satisfying because it delivers:

• Creamy interior
• Cheesy richness

How to Make This Casserole Extra Flavorful

1️⃣ Season the Beef Well
