How to Use Peanut Oil in Cooking

Peanut oil is a highly versatile cooking oil prized for its neutral flavor, high smoke point, and various health benefits.

When using peanut oil in your cooking, it’s essential to understand its properties and how it can enhance your culinary creations.

This oil is suitable for a wide range of cooking methods, from deep-frying to sautéing, without overpowering the natural taste of the ingredients.

Refined peanut oil, in particular, is excellent for high-temperature cooking, making it an ideal choice for frying foods to achieve that perfect crispy texture.

Its high smoke point means it can be heated to high temperatures without smoking or breaking down, ensuring your meals are not only delicious but also cooked safely.

For those with peanut allergies, it’s important to note that refined peanut oil is typically considered allergen-free due to the refining process removing the protein components that trigger allergic reactions.

Incorporating peanut oil into your culinary regimen can also have benefits beyond the kitchen.

Renowned for its heart-healthy qualities, peanut oil can be a smart swap for fats that are solid at room temperature.

When stored correctly, unopened peanut oil has a long shelf life, ensuring you can readily have this heart-healthy oil on hand for any cooking endeavor.

Choose virgin or cold-pressed peanut oil if you’re looking to impart a subtle peanut flavor to dishes such as dressings or dips, adding an aromatic touch to your meals.

Types of Peanut Oil

Peanut oil comes in various types, each with distinct properties and uses in cooking. Understanding the differences will help you choose the right oil for your dish.

Refined Peanut Oil

Refined peanut oil, a favorite for deep frying, has been processed to remove flavors and impurities, which gives it a high smoke point and a neutral flavor.

This makes it ideal for cooking at high temperatures without altering the taste of your food.

Cold-Pressed Peanut Oil

Cold-pressed peanut oil, also known as virgin peanut oil, is extracted using a mechanical method that maintains more of its natural flavors.

It has a nutty flavor that can enhance dressings, marinades, and dipping sauces.

Unrefined Peanut Oil

Unrefined peanut oil is less processed than the refined variety, retaining a strong nutty flavor and a lower smoke point.

Best suited for medium-heat cooking, it can add a distinct peanut taste to your dishes.

Roasted Peanut Oil

Roasted peanut oil is made from peanuts that have been roasted prior to oil extraction, imparting a robust, nutty flavor.

It’s commonly used as a finishing oil to add flavor to your dishes right before serving.

Health and Nutrition

When using peanut oil in cooking, you’re not just choosing a versatile oil for its high smoke point; you’re also selecting an oil with notable health and nutritional benefits.

This oil can support heart health and provides valuable nutrients, though it’s important to use it mindfully if you have peanut allergies.

Heart-Healthy Fats

Peanut oil is rich in monounsaturated fats, which can be beneficial for your heart.

Including monounsaturated fats in your diet can help decrease low-density lipoprotein (LDL) or “bad” cholesterol levels, which reduces the risk of cardiovascular disease.

In contrast, peanut oil contains lower amounts of saturated fats, which are commonly linked to heart problems when consumed in excess.

It also offers polyunsaturated fats, including omega-6 fatty acids, which should be balanced with omega-3 fats in your diet to manage inflammation.

Vitamin E and Antioxidants

This oil is a good source of vitamin E, an antioxidant that protects your cells from free radicals.

Free radicals can cause cell damage that potentially leads to cancer and other diseases.

Regular consumption of vitamin E supports your immune system and reduces inflammation, contributing to overall health.

Additionally, peanut oil contains phytosterols, compounds that can further benefit cholesterol levels and cardiovascular health.

Allergy Considerations

While the nutritional profile of peanut oil can be advantageous, it’s crucial to recognize the implications for individuals with peanut allergies.

Highly refined peanut oil may be safe for some people with peanut allergies, as the refining process removes allergenic proteins.

However, unrefined or cold-pressed oils might still contain these proteins and could trigger allergic reactions.

Always consult your doctor if you have a peanut allergy before incorporating peanut oil into your diet.

Cooking with Peanut Oil

Peanut oil, prized for its high smoke point and neutral taste, is a versatile choice in your kitchen. Whether you’re frying, sautéing, or preparing dressings, understanding how to use peanut oil can elevate your culinary creations.

Frying and Deep-Frying

When deep-frying or frying at high temperatures, you want an oil that remains stable, and peanut oil is an exemplary choice.

It boasts a high smoke point of around 450°F, ensuring your food can be cooked thoroughly without the oil smoking or breaking down.

  • Refined Peanut Oil: Opt for this when heat is essential; it’s ideal for crispy fried foods.
  • Unrefined Peanut Oil: Choose this for added flavor, suitable for milder frying.


Stir-frying requires an oil that can handle constant high heat and vigorous movement.

Peanut oil’s high smoking point and its ability to retain a neutral taste under such conditions make it an excellent candidate.

  • Performance: Peanut oil doesn’t overshadow the flavors of your ingredients, making it a go-to for stir-frying diverse dishes.


Peanut oil’s subtle taste and heat tolerance also make it a preferred oil for baking.

Use it for a healthier option without compromising the texture of your baked goods.

  • Texture & Flavor: It contributes to a moist texture without altering the intended flavor profile of your recipes.

Salad Dressings and Marinades

Oils that are liquid at room temperature, like peanut oil, are often recommended for their health benefits.

Its benign taste complements, rather than competes with, the flavors of dressing and marinade ingredients.

  • Benefits: Peanut oil offers a healthy base for creating vibrant, nutrient-rich dressings and marinades.

Comparing Cooking Oils

When selecting a cooking oil, you should consider the flavor profiles, smoke points, and health benefits to find one that best suits your culinary needs. Here’s how peanut oil stacks up against other popular cooking options.

Versus Vegetable Oils

Vegetable oils are a broad category that includes canola oil, sunflower oil, safflower oil, and more.

These are often valued for their neutral taste and moderate smoke points, making them versatile for various cooking methods.

Peanut oil, in contrast, has a distinct nutty flavor and a higher smoke point, ideal for frying and high-heat cooking. It’s also a heart-healthy option due to its monounsaturated fat content.

  • Neutral taste: Vegetable oils
  • High smoke point: Peanut oil
  • Best for frying: Peanut oil

Versus Olive Oil

Olive oil comes in various grades, with extra virgin olive oil having a low smoke point and strong flavor, better suited for dressings and low-heat cooking.

Refined olive oils can be used for medium to high-heat applications, but still not as high as peanut oil’s smoke point.

If you’re after a light taste, refined olive oil is a suitable substitute, but for high-heat cooking like searing and frying, peanut oil is your go-to.

  • Flavor profile: Olive oil (strong), Peanut oil (nutty)
