Can You Mix Vegetable Oil And Peanut Oil?

Cooking oil is an essential ingredient in many dishes, whether used for frying, sautéing, baking, grilling, or as a salad dressing. There is a wide variety of oils available in the market, with peanut oil and vegetable oil being two of the most popular choices in the US.

Each oil has its own unique advantages and disadvantages, and while they work well individually, a common query is whether they can be combined. Reasons for mixing these oils could include running low on either type or simply wanting to experiment with a new blend.

It is possible to mix peanut oil and vegetable oil; however, it is crucial to consider that the combined oils will adopt the lower smoking point of the two. For example, if peanut oil has a smoking point of 450°F and vegetable oil has a smoking point of 400°F, the mixed oil will have a smoking point of 400°F.

Read on to explore the consequences of blending these popular oils and whether they can be combined for frying, baking, and cold dishes.

Understanding vegetable oil and peanut oil

  • Vegetable oil: Vegetable oil is a generic term used to describe a wide variety of plant-based oils that are derived from different sources such as soybeans, canola, corn, sunflower, safflower, and palm. It is a highly processed oil that is refined and purified to remove impurities, making it suitable for cooking, frying, and baking.
  • Peanut oil: Peanut oil, also known as groundnut oil, is a type of vegetable oil that is derived from peanuts. It is a popular cooking oil in many parts of the world, especially in Asian cuisine. Peanut oil is high in monounsaturated and polyunsaturated fats, which are considered healthier than saturated fats.

The main difference between vegetable oil and peanut oil is their flavor and composition.

Vegetable oil is a blend of different types of oils, while peanut oil is derived specifically from peanuts.

Peanut oil has a distinct nutty flavor, whereas vegetable oil has a neutral flavor. Additionally, peanut oil has a higher smoke point than most vegetable oils, making it more suitable for high-temperature cooking methods like deep-frying.

However, peanut oil is not recommended for people with peanut allergies, while vegetable oil is generally considered safe for consumption by most people.

When you mix peanut oil and vegetable oil, what happens?

When peanut oil and vegetable oil are mixed, it is generally a safe process without significant risks. People have been combining oils for various purposes for a long time. However, it is essential to be aware of the specific vegetable oil being used, as not all are the same. Always check the label to ensure it is safe to mix with other oils.

It’s worth noting that many vegetable oils used in home cooking are already a combination of different oils. These oils undergo rigorous testing for chemical composition, compatibility, taste, and smoking points before being blended. Since such tests cannot be conducted on peanut and vegetable oils at home, questions about safety and taste may arise. Fortunately, there are no major concerns, and the oils can be mixed safely. Just remember to consider the smoking points of both oils and use the lower one when cooking.

Another important point is that peanut oil contains allergens that can be harmful to those with peanut allergies.

Can you mix vegetable oil and peanut oil?

People might want to mix vegetable oil and peanut oil for a variety of reasons. One reason might be to enhance the flavor of their cooking, as peanut oil has a distinct nutty flavor that can add depth to dishes. Another reason might be to achieve a desired smoke point, as different oils have different smoke points and can be combined to increase the overall smoke point of the mixture. Additionally, some people might mix the oils for health reasons, as vegetable oil is high in polyunsaturated fats while peanut oil is high in monounsaturated fats.

When mixing oils, there are several factors to consider, including smoke point, flavor, and health benefits. Smoke point is particularly important, as it determines the maximum temperature at which an oil can be heated before it starts to smoke and break down, producing harmful compounds. It is also important to consider the ratio of oils being mixed, as different oils have different properties and can affect the overall flavor and health benefits of the mixture.

Advantages of mixing vegetable oil and peanut oil include enhanced flavor and a higher smoke point. Additionally, the combination of polyunsaturated and monounsaturated fats in the mixture can provide a more balanced ratio of healthy fats. However, some potential disadvantages of mixing oils include a higher cost compared to using a single oil, as well as the potential for allergenic reactions in people with peanut allergies.

If you decide to mix vegetable oil and peanut oil, it is recommended to use a 1:1 ratio of the oils. It is also important to consider the smoke point of the oils, as the mixture should not be heated beyond the smoke point of the lowest smoke point oil in the mixture. Additionally, it is important to keep in mind any potential allergies or sensitivities to peanut oil in those who will be consuming the food.

What impact does mixing oils have on the taste of your meal?

The majority of cooking vegetable oils possess a neutral flavor, which is why combining them might not significantly affect the taste.

Nonetheless, peanut oil has a rather distinct taste, so be ready for a nutty undertone in your dish if you mix it with vegetable oil, especially in significant amounts like deep-frying.

In smaller quantities, the impact on the food’s flavor will be minimal.

When using unprocessed oil for cold dishes, such as salads, the oil’s taste remains more pronounced and powerful compared to when it’s heated.

In these instances, it’s crucial to take into account the potential shift in flavor when blending two oils.

If a recipe requires peanut oil as a dressing, combining it with vegetable oil could diminish the delightful, nutty taste of the peanut oil.

Moreover, specific oils are employed to enhance the flavors of particular cuisines, for example, peanut oil in Thai dishes and olive oil in Italian meals. Mixing them with other oils might significantly alter the food’s taste.

When using oils for baking purposes, like cake preparation, most recipes typically call for vegetable oil. However, combining oils with similar smoke points shouldn’t pose a problem.

Mixing peanut oil with vegetable oil shouldn’t drastically change your recipe. It might, though, impart a subtle nutty nuance to the recipe, which, in our view, could potentially elevate the cake’s overall taste.

Cooking with mixed oils

Tips for cooking with mixed oils:

  1. Choose oils that have similar smoke points to ensure they cook evenly.
  2. Use a neutral-flavored vegetable oil as the base oil and add small amounts of peanut oil for flavor.
  3. Mix the oils thoroughly before use to ensure even distribution.
  4. Use mixed oils for cooking methods that require high heat, such as stir-frying, deep-frying, or searing.

Best dishes to use mixed oils for:

  1. Asian-style stir-fries: Mixed oils can add depth and complexity to the flavors of stir-fried dishes such as beef and broccoli or vegetable stir-fry.
  2. Fried foods: Mixed oils can be used for frying foods like chicken, fish, or French fries.
  3. Salad dressings: A mixture of vegetable and peanut oil can add a unique flavor to homemade salad dressings.


In conclusion, mixing vegetable oil and peanut oil is not only possible but can also create interesting flavors and textures in your culinary creations.
