Peanut Oil

Peanut oil, also known as groundnut oil, is a mild-tasting vegetable oil derived from peanuts. It is available year-round and is a popular choice for frying due to its high smoke point, which allows it to be used for cooking at high temperatures without burning. Peanut oil is a staple in Asian, African, and Southern American cuisines, often used for deep-frying, stir-frying, and as a dressing for salads. Its neutral flavor makes it versatile in the kitchen, complementing a wide range of dishes without overpowering other ingredients.

How to Choose Peanut Oil

When selecting peanut oil, consider the intended use. For high-heat cooking like deep-frying, refined peanut oil with its high smoke point is ideal. For dressings or dishes where the flavor of the oil is prominent, cold-pressed or gourmet peanut oils offer more depth. Always check for clarity and freshness, and avoid oils that appear cloudy or have an off smell, as this can indicate rancidity.

Cooking/Prep Tips for Peanut Oil

Peanut oil is a versatile cooking oil with a high smoke point, making it ideal for frying and sautéing. When using peanut oil, it's important to consider its smoke point of around 450°F (232°C), which allows you to cook at higher temperatures without the oil smoking or breaking down, preserving the food's flavor and the oil's nutritional benefits. For intermediate and expert home cooks, it's also worth noting that refined peanut oil is allergen-free, as the refining process removes the protein that causes allergic reactions. However, always be mindful of guests with peanut allergies when using this oil.

Shelf Life of Peanut Oil

Peanut oil should be stored in a cool, dark place to prevent rancidity. Unopened bottles can be kept in the pantry, while opened bottles should be tightly sealed and can be refrigerated to extend shelf life. Refined peanut oil has a longer shelf life than cold-pressed or gourmet varieties. Always smell the oil before use; if it has a sour or off odor, it may be rancid and should not be used.

Cooking Techniques for Peanut Oil

Deep Frying: Peanut oil is commonly used for deep frying due to its high smoke point. It remains stable at high temperatures, resulting in a crispy exterior without absorbing excess oil. Perfect for frying chicken, tempura, or French fries.

Stir-Frying: Its nutty flavor and ability to withstand high heat make peanut oil a staple in stir-frying. It can handle the quick cooking of vegetables and meats while imparting a subtle flavor that doesn't overpower the dish.

Dressing and Marinades: While not a cooking technique, peanut oil's bold flavor makes it suitable for dressings and marinades, especially in Asian-inspired recipes. It can be combined with vinegar or citrus juices and various seasonings to create a flavorful base for salads or to tenderize and flavor meats before cooking.
