A 5-ingredient casserole inspired by Dolly Parton that’s perfect for busy nights. With layers of ground beef, green beans, mushroom soup, cheesy mashed potatoes, and gooey cheddar, it’s a hearty, comforting dinner ready in 30 minutes.

  • Total Time: 30 minutes
  • Yield: 4–6 servings

Ingredients

  • 1 lb ground beef (80/20 or lean)
  • 1 can (10.5 oz) cream of mushroom soup
  • 1 can (15 oz) green beans, well drained
  • 1 cup shredded cheddar cheese
  • 1 package (6 oz) instant mashed potatoes, prepared according to directions

Instructions

  1. Preheat oven to 375°F (190°C).
  2. In a skillet over medium heat, cook ground beef for 5–7 minutes until browned. Drain excess fat.
  3. In a medium casserole dish (8×11″ or similar), layer cooked beef on the bottom.
  4. Add drained green beans as the second layer.
  5. Spoon cream of mushroom soup evenly over the top (no need to mix).
  6. Spread prepared mashed potatoes over the soup layer using the back of a spoon.
  7. Sprinkle shredded cheddar cheese on top.
  8. Bake uncovered for 25 minutes until bubbly and golden around the edges. Optional: Broil for 1 minute for extra crispy cheese.
  9. Let rest 5 minutes before serving.

Notes

  • Use real mashed potatoes if preferred—just keep them thick.
  • Swap beef for ground turkey or chicken; add a splash of Worcestershire for flavor.
  • Try different cheeses like pepper jack or smoked gouda for variation.
  • For fresh green beans, blanch them for 3 minutes first.
  • Make ahead and refrigerate—just add 5 extra minutes when baking.
