Best Oils For Frying On Keto: A Comprehensive Guide

The ketogenic diet is a low-carb, high-fat diet that requires a lot of cooking oil. While all oils are pure fat and don't contain any carbs, some are better than others from a health perspective. When choosing a cooking oil, it's best to opt for those with a high smoke point, which is the temperature at which an oil starts to smoke. Using oils with a high smoke point ensures that the beneficial nutrients in the oil are not destroyed. Some of the best oils for frying on a keto diet include avocado oil, coconut oil, olive oil, peanut oil, ghee, tallow, and lard.

Avocado oil is flavourful and has a high smoke point

Avocado oil is a flavourful and nutritious oil, well-suited to a variety of cooking methods, including frying. It is a mild, versatile vegetable oil with a rich, nutty flavour that complements sautéed and pan-fried foods. Avocado oil is also packed with vitamins A, E, and D, as well as proteins and potassium.

One of the key benefits of avocado oil is its high smoke point. With a smoke point of approximately 500°F (260°C), it is ideal for frying as it can create extra-crispy fried foods without burning them. The smoke point of an oil is the temperature at which it starts to burn and smoke. When an oil reaches its smoke point, the flavour changes to a burnt taste, and the beneficial nutrients in the oil are destroyed. Oils with higher smoke points are better for deep frying or high-heat cooking.

Avocado oil is also a good choice for keto because it is high in monounsaturated fats and antioxidants, which can help reduce blood pressure, eliminate belly fat, combat inflammation, lower cholesterol levels and increase heart health.

However, one drawback of avocado oil is that it tends to be more expensive than other common oils such as olive and coconut oil.

Coconut oil is solid at room temperature

Coconut oil is a unique plant-based oil extracted from coconut flesh. It is solid at room temperature because of its high saturated fat content, which is typically only seen in animal fats. Coconut oil has a relatively low smoke point of 350°F (177°C), which is the temperature at which an oil begins to smoke. As such, it may be more suitable for baking and low-heat cooking rather than high-heat cooking like frying or stir-frying.

One drawback of coconut oil is that it imparts a coconut taste to foods that are cooked with it. However, refined coconut oil is flavourless and has a higher smoke point of 450°F (232°C). Nevertheless, this product is more processed than unrefined coconut oil.

Coconut oil is also a popular choice for topical skin purposes. It can help alleviate dry skin and add moisture, as well as help treat acne, eczema, psoriasis, dermatitis, rashes, or dry and flaky skin. It can also be used to treat a dry and flaky scalp, aid in controlling dandruff, and repair dry and damaged hair.

Coconut oil is widely promoted as having many health benefits, and some believe it to be one of the healthiest foods on the planet. It is stable as a cooking oil, rich in medium-chain fatty acids, easy for your body to digest, antimicrobial and antifungal, and particularly rich in lauric acid, which is known to boost the immune system. However, it is important to note that coconut oil consumption can result in significantly higher LDL (bad) cholesterol compared to consuming non-tropical vegetable oils.

Olive oil is versatile and healthy

Olive oil is a versatile and healthy option for those following a keto diet. It is the natural oil extracted from olives, the fruit of the olive tree. Olive oil is known for its rich flavour, versatility, and health benefits. It has a distinct taste and aroma, which can slightly alter the flavour profile of dishes. It is an excellent source of monounsaturated fats, antioxidants, and vitamins E and K.

Extra virgin olive oil is the least processed variety and is considered the healthiest type of olive oil. It retains antioxidants and bioactive compounds found in olives, giving it a higher nutritional value than refined olive oil. It is also loaded with monounsaturated fatty acids, which have been linked to improved heart health and a reduced risk of heart disease. The oil's predominant fatty acid, oleic acid, is known to reduce inflammation and oxidative stress and may have beneficial effects on genes.

Olive oil is a good choice for cooking due to its high smoke point, which is the temperature at which an oil starts to smoke. Its smoke point is approximately 356°F (180°C), making it suitable for high-heat cooking methods such as frying, roasting, grilling, and sautéing. It is also a healthy option for baking, stir-frying, salad dressings, and marinades.

In addition to its culinary uses, olive oil has been studied for its potential health benefits. It has been associated with a reduced risk of heart disease, stroke, cancer, Alzheimer's disease, and type 2 diabetes. Its anti-inflammatory properties may also help in treating rheumatoid arthritis. Furthermore, olive oil has antibacterial properties and can inhibit or kill harmful bacteria such as Helicobacter pylori (H. pylori).

Ghee is a saturated fat with a high smoke point

Ghee, a type of clarified butter, is a saturated fat with a high smoke point. It is made by heating butter and removing the milk proteins that accumulate during the heating process. This results in a flavorful butter that is often used in Indian cooking and solidifies at room temperature. Ghee has a smoke point of 485°F, making it ideal for high-heat cooking and deep frying. Its high smoke point and delicious buttery flavour have made it a popular choice for cooking.

Ghee is a good option for those who are sensitive to dairy as the milk proteins are removed. However, those with a dairy allergy should still avoid ghee as it may contain traces of dairy proteins that can trigger an allergic reaction. Ghee is also a source of vitamins A, E, and K2, as well as trace minerals.

When choosing an oil for frying, it is important to consider the smoke point, which is the temperature at which an oil starts to burn and smoke. Oils with higher smoke points are better for deep frying or high-heat cooking. Ghee's high smoke point makes it a suitable option for these cooking methods. Additionally, its flavour and versatility make it a good choice for various dishes, such as fried or scrambled eggs and oven-roasted meats and vegetables.

Ghee can be stored in an airtight container at room temperature for up to a year or in the refrigerator for a longer period. Its versatility, flavour, and high smoke point make it a popular choice for high-heat cooking and frying on the keto diet.

Animal fats are suitable for keto cooking

Animal fats can impart a unique, meaty flavour to dishes, and they are fairly stable when heated, making them great for high-heat cooking, roasting, and frying. Some examples of animal fats include lard, tallow, and duck fat.

Lard is rendered pig fat and is considered one of the best oils for deep frying and shallow frying. It has a high smoke point of 374°F/190°C and a neutral flavour that does not infuse the food being cooked. It is also lower in saturated fats and higher in monounsaturated fats than other animal fats.

Tallow is rendered fat from animals other than pork and is commonly derived from beef. It is another excellent fat for high-heat cooking or frying and has long been a favourite among chefs due to its amazing flavour, high smoke point, and resistance to rancidity. Tallow is high in vitamins A, D, E, and K, as well as antioxidants.

Duck fat has a uniquely rich flavour and its fatty acid composition makes it superior to chicken fat for cooking. It can be used to pan-fry or roast meats and vegetables, or simply melted on top of a keto meal to boost its healthy fat content.

When choosing animal fats for keto cooking, it is important to select those derived from pasture-raised, grass-fed animals, as these tend to be the healthiest and most flavourful options.
