Understanding Peanut Oil's Characteristics
Before looking for a substitute, it's helpful to understand what makes peanut oil a popular choice for many cooks. It is prized for two key attributes: a high smoke point and a neutral flavor profile. The refining process removes most of the allergenic proteins and strong flavor compounds, leaving a clean, versatile oil perfect for searing, stir-frying, and deep frying. For specialty dishes that require a nutty flavor, a less common cold-pressed or gourmet peanut oil is used. The best substitute, therefore, depends on which characteristic is most important for your recipe.
Canola Oil: The All-Purpose Alternative
Refined canola oil, derived from the rapeseed plant, is one of the most widely recommended substitutes and is arguably the oil that is closest to peanut oil in terms of overall function. It boasts a high smoke point of around 400°F (204°C), making it suitable for many high-temperature cooking tasks. Canola oil also has a very light, neutral flavor, ensuring it won't overpower the other ingredients in a dish. It is also significantly more affordable and widely available than peanut oil. For those concerned about peanut allergies, canola oil is a completely safe, non-legume-based alternative. It is a versatile workhorse in the kitchen, capable of handling everything from baking to deep-frying. For the majority of cooking applications, refined canola oil is the most practical and direct replacement.
Sunflower and Safflower Oils: High-Heat Specialists
When the primary concern is a very high smoke point for intense frying, high-oleic sunflower oil and safflower oil are exceptional choices. Refined sunflower oil has a smoke point of about 450°F (232°C), matching that of peanut oil. It provides a neutral flavor and is rich in Vitamin E. Safflower oil, a relative of the sunflower, offers an even higher smoke point, ranging from 440°F to 520°F (227°C to 271°C), making it one of the most stable oils available for high-heat cooking. Like canola and sunflower, it has a neutral flavor and is heart-friendly due to its unsaturated fat content. Both of these are excellent options if you frequently perform deep-frying, stir-frying, or searing.
The Nutty Flavor Substitute: Sesame Oil
While other oils may match the high smoke point, they lack the characteristic nutty flavor of unrefined or gourmet peanut oil. For recipes where this flavor is desired, toasted sesame oil is the best substitute. However, it is crucial to note the difference between regular and toasted sesame oil. Regular sesame oil has a higher smoke point similar to peanut oil and a lighter flavor, while toasted sesame oil has a distinctively strong, nutty flavor but a much lower smoke point. For this reason, toasted sesame oil should not be used for high-heat frying but rather added at the end of cooking or used in sauces and dressings to impart flavor.
Vegetable Oil (Blends)
Generic vegetable oil, often a blend of soybean and/or corn oil, is another common and affordable substitute for refined peanut oil. It shares a similar neutral flavor and a comparable smoke point (400–450°F or 204–232°C), making it a reliable, budget-friendly alternative for most cooking needs. Check the label, as blends can vary, but most are suitable for frying, baking, and general cooking.

Conclusion: Choosing the Best Peanut Oil Alternative
Ultimately, the choice of the oil that is closest to peanut oil depends on your specific culinary needs. For a universal, budget-friendly replacement that works well for most high-heat applications, refined canola oil is the top contender. If your primary goal is maximum heat stability for deep frying, high-oleic sunflower oil or safflower oil are superior options. For adding a nutty flavor without the allergens, toasted sesame oil is the best choice, but it should be used cautiously and not for deep frying due to its lower smoke point. Finally, general vegetable oil is a perfectly acceptable, cost-effective substitute for everyday cooking needs. Consider your recipe's requirements and any dietary restrictions to select the perfect alternative. When in doubt for a neutral, high-heat cooking oil, a good quality canola or sunflower oil will serve you well. A reliable resource for comparing different cooking oils is The Cooks Thesaurus.
