Each ingredient in this Sausage potato casserole plays an important role. Additionally, here are helpful substitutions if needed:

• Breakfast Sausage - Adds savory flavor and heartiness. Substitute: turkey sausage, chicken sausage, or plant-based sausage.
• Butter - Adds richness and helps sauté the onion. Substitute: olive oil or avocado oil.
• Frozen Shredded Potatoes, thawed - Make the casserole hearty and creamy as they bake. Substitute: diced hashbrowns or fresh grated potatoes.
• Cream of Mushroom or Cream of Chicken Soup - Adds creaminess and binds the casserole beautifully. Substitute: gluten free works well in this recipe or use a homemade white sauce.
• Milk - Thins the soup and helps create a velvety texture. Substitute: heavy cream, half-and-half, almond milk, or oat milk.
• Shredded Cheese - Creates irresistible melt and flavor. Substitute: cheddar, Colby Jack, Monterey Jack, or a dairy-free cheese alternative.
• Salt - Enhances overall flavor. Substitute: seasoned salt (reduce quantity), or omit if sausage is salty.
