Ingredients Overview

Ground Beef Mixture

• Lean Ground Beef (85–90%): Holds together well without being greasy.

• Breadcrumbs: Help bind and give the meat mixture structure.

• Egg: Adds moisture and keeps the casserole tender.

• Onion & Garlic: Diced fine for flavor and texture.

• Worcestershire Sauce: Brings umami and depth.

• Ketchup or Tomato Paste: Traditional and essential for meatloaf flavor.

• Seasonings: Salt, black pepper, onion powder, and dried herbs like parsley or thyme.

Mashed Potatoes

• Russet or Yukon Gold Potatoes: Starchy and ideal for mashing.

• Butter & Milk: For richness and creaminess.

• Sour Cream or Cream Cheese (optional): Adds tang and ultra-smooth texture.

• Salt & Pepper: Season well so the potatoes stand on their own.

Cheese

• Shredded Cheddar Cheese: Melts beautifully and adds bold, savory flavor.

• Optional: Add mozzarella for extra stretch or pepper jack for a kick.

Optional Extras

• Vegetables: Add frozen peas, corn, or green beans to the meat layer for a full meal.

• Topping Garnish: Chopped parsley or green onions for a fresh finish.
