Olive Oil (Best Option)
1:1 (1 tablespoon olive oil per 1 tablespoon butter)Olive oil is a liquid fat at room temperature, which helps to evenly distribute fat throughout the meat mixture, preventing dryness. Its monounsaturated fats contribute to a moist and tender texture by lubricating the protein fibers during cooking.
To use olive oil effectively, mix it thoroughly with the meat and other ingredients to ensure even fat distribution. Avoid using extra-virgin olive oil with very strong flavors to keep the meatloaf’s taste balanced.
Compared to butter, olive oil results in a slightly less rich flavor but improves moisture retention and tenderness, making it an excellent substitute in meatloaf.
