Ingredients

Main Layer:

  • 1 pound ground beef or ground turkey
  • 1 large onion, diced
  • 2 cloves garlic, minced
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • 1 teaspoon Worcestershire sauce
  • ½ teaspoon paprika (optional)

Green Bean Layer:

  • 3 cups fresh green beans, trimmed and steamed
    (or 2 cans of drained green beans / 1 bag of thawed frozen green beans)

Creamy Sauce Layer:

  • 1 can (10.5 oz) cream of mushroom soup (or cream of celery/chicken)
  • ½ cup sour cream or plain Greek yogurt
  • ½ teaspoon onion powder
  • ½ teaspoon garlic powder
  • 1 cup shredded cheddar cheese (for mixing)

Cheese Topping:

  • 1 ½ cups shredded cheddar cheese

Crunchy Topping:

  • 1 ½ cups crispy fried onions (French’s or any brand you like)

Step-by-Step Instructions

STEP 1: Cook the Ground Meat Mixture

  1. In a large skillet over medium heat, brown the ground beef or turkey until no longer pink (about 6–8 minutes).
  2. Add the diced onion and minced garlic, and cook for another 4–5 minutes until the onion becomes soft and translucent.
  3. Season the mixture with salt, black pepper, Worcestershire sauce, and paprika.
  4. Stir well and let it simmer for 2 minutes, then remove from heat.

Pro Tip: Drain any excess fat from the skillet before moving to the next step if using regular ground beef.

STEP 2: Pre-Cook the Green Beans

  • Fresh Green Beans: Trim and steam for 8–10 minutes until just tender.
  • Frozen Green Beans: Thaw and pat dry.
  • Canned Green Beans: Drain well and pat dry with paper towels.

Spread the green beans across the bottom of a greased 9×13-inch casserole dish to create a fresh and crisp veggie base.

STEP 3: Make the Creamy Filling

  1. In a mixing bowl, combine:
    • 1 can cream of mushroom soup
    • ½ cup sour cream
    • ½ teaspoon onion powder
    • ½ teaspoon garlic powder
    • 1 cup shredded cheddar cheese
  2. Stir until creamy and well-blended.
  3. Add the cooked beef mixture into the creamy filling and stir to combine.

STEP 4: Assemble the Casserole

  1. Layer 1: Spread the green beans evenly across the bottom of your casserole dish.
  2. Layer 2: Spoon the creamy beef mixture over the green beans and gently smooth out the surface with a spatula.
  3. Layer 3: Sprinkle the remaining 1½ cups of shredded cheddar cheese evenly across the top.
  4. Layer 4: Finally, top with crispy fried onions for a golden, crunchy crown.

STEP 5: Bake

  1. Preheat your oven to 375°F (190°C).
  2. Cover the casserole with foil and bake for 20 minutes.
  3. Remove foil and bake for an additional 10–15 minutes, until the cheese is bubbly and the onions are golden brown.

Optional: Broil the casserole for 2 minutes at the end to get an extra crispy topping — just keep a close eye so it doesn’t burn!

STEP 6: Cool & Serve

  • Let the casserole rest for 5–10 minutes before slicing.
  • Serve warm with a side salad, crusty bread, or mashed potatoes for a full meal.

Pro Tips & Variations

Customization Ideas:

  • Add Bacon: Crumble 4 slices of crispy cooked bacon into the beef mixture for smoky flavor.
  • Spice It Up: Add diced jalapeños or a dash of cayenne to the sauce for heat.
  • Add Mushrooms or Peas: For a veggie boost, stir in a handful of chopped mushrooms or peas into the meat mix.

Cheese Variations:

  • Swap out cheddar for Monterey Jack, pepper jack, or mozzarella for a different cheese pull.

Keto/Low-Carb Option:

  • Use a homemade low-carb mushroom sauce instead of canned soup.
  • Skip the fried onions and top with crushed pork rinds or almond flour crumble.
