 Ingredients & Why They Matter

 Beef Layer:

• 1 lb ground beef
  → The protein-packed base of the dish. Choose 80/20 for balanced flavor and fat.

• 1 small onion, finely chopped
  → Adds sweet and savory depth to the beef.

• 2 cloves garlic, minced
  → Enhances the savory flavor and adds richness.

• 1 tablespoon tomato paste
  → Gives umami and body to the beef mixture.

• 1 teaspoon Worcestershire sauce
  → Adds a bold, savory punch that deepens flavor.

• Salt & pepper to taste
  → Essential for seasoning every layer.

 Mashed Potato Layer:

• 3 cups mashed potatoes (about 4 medium potatoes)
  → Creamy, buttery topping that brings the whole casserole together.

• 2 tablespoons butter
  → Adds richness to the potatoes.

• ¼ cup sour cream or cream cheese
  → Makes the mashed potatoes ultra-creamy and tangy.

• ½ cup milk
  → Adjusts texture to make the mash smooth and spreadable.

• Salt to taste
  → Brings out the potato flavor.

 Topping:

• 1½ cups shredded cheddar cheese (or your favorite blend)
  → Melts beautifully and gives that golden, irresistible crust.

• Optional: Chopped green onions or parsley
  → For a pop of freshness and color.

🧠 Shortcut Tip: Use leftover mashed potatoes or quality store-bought mash to save time.
