Donuts are the ultimate sweet indulgence, prized for their warm, pillowy texture and irresistible flavor. But many don’t realize that the type of oil you fry them in is just as important as the dough's ingredients when crafting the perfect donut. The right oil can significantly influence a donut’s taste, mouthfeel, and appearance. We’ve rounded up the five best oils for frying donuts, selected for their neutral or close-to-neutral taste, high smoke point, and affordability.

1. Vegetable Shortening

The oil of choice for many donut chains, including the famous Krispy Kreme, vegetable shortening is ideal for all donut types due to its versatility, neutral flavor, and cost-effectiveness. Typically made from soybean or a blend of vegetable oils, it gives donuts a light golden color, airy texture, and crisp exterior without altering the flavor. It comes in solid and liquid forms, with the solid variety offering better consistency and stability during frying.

Shortening creates a firm texture with a tender crumb, achieving the perfect balance of crispy outside and soft inside. With a higher melting point than liquid oils, the donut absorbs less oil, resulting in a less greasy product. Its high smoke point also allows it to withstand the high temperatures needed for frying without breaking down or affecting flavor. Make sure to choose a vegetable shortening specifically made for frying since baking shortening has a much lower smoke point.

  • Vegetable Shortening Smoke Point: 360 to 450 degrees Fahrenheit (182 to 232 Celsius)

2. Canola Oil

Canola oil rivals vegetable shortening as the top choice for frying donuts and is a great alternative. Since it’s liquid at room temperature, it coats the donuts more evenly, resulting in a more delicate crust, tender crumb, and lighter golden color compared to shortening. The neutral taste ensures that the natural sweetness of the donuts shines through without being overshadowed by the oil itself.

Canola oil is a healthier alternative, with lower levels of saturated fats and higher amounts of heart-healthy omega-3 fatty acids. While slightly more expensive than vegetable shortening, it remains a cost-effective option, especially if you’re looking for an oil to use across various menu segments. Versatile in its uses, canola oil is ideal for a wide range of culinary applications, including baking, salad dressings, deep frying, and grilling.

3. Palm Oil

Palm oil is known for its stability, which is why it is the preferred choice for many commercial donut chains, including Dunkin' Donuts. It gives donuts a crisp, firm bite while yielding a soft center. It is generally inexpensive and is not derived from seeds, making it a cost-effective option to seed oils without sacrificing performance.

It's important to note that palm oil production has significant environmental concerns, particularly concerning deforestation and habitat destruction. If eco-friendly practices are integral to your business model, prioritize sourcing palm oil from certified, ethically managed sources.

4. Cottonseed Oil

Cottonseed oil is the preferred choice for frying beignets, a classic French donut. Its high smoke point and neutral flavor make it perfect for achieving the light, airy texture and crisp golden-brown exterior that defines a great beignet, and these same qualities make it equally effective for other types of donuts.

Though it ranks in the middle in terms of affordability on our list, its exceptional stability and high smoke point allow it to be reused multiple times without sacrificing the quality of the food or the oil, making it a cost-effective option over time.

  • Cottonseed Oil Smoke Point: 420 degrees Fahrenheit (216 degrees Celsius)
  • Cottonseed Oil Price Point: $$

5. Peanut Oil

Refined peanut oil is made by pressing, filtering, and purifying raw peanuts, resulting in a light color and mildly nutty flavor that is versatile enough for all types of donuts. It works particularly well if you're planning to coat your donuts with crushed nuts or glaze them with peanut butter, as the subtle nutty taste complements these flavors. Its high smoke point makes it one of the best oils for deep frying foods, ensuring a consistent fry that results in a crisp exterior and soft, fluffy interior. While it’s the most expensive oil on this list, its price is justified by its high performance.

Highly refined peanut oil is considered safe for most people with peanut allergies, as the protein that causes reactions is removed. However, if you choose to use this oil, your menu should clearly state that your items are fried in peanut oil to ensure customer safety.

  • Peanut Oil Smoke Point: 450 degrees Fahrenheit (232 degrees Celsius)

What Oils Should You Avoid When Frying Donuts?

When frying donuts, it's important to choose oils that can handle deep fryer temperatures without burning or imparting strong flavors. Therefore, it's best to avoid oils with a low smoke point or those with a strong, distinctive flavor. Here are some oils to avoid:

  • Extra Virgin Olive Oil: While olive oil has health benefits, extra virgin olive oil has a relatively low smoke point, which makes it unsuitable for deep frying. Additionally, its rich, vegetal flavor will alter the taste of your donuts and isn’t the best pairing with sugary glazes and toppings.
  • Unrefined Coconut Oil: Unrefined coconut oil has a smoke point of around 350 degrees Fahrenheit (175 degrees Celsius), which is at the low end for frying donuts and might not be enough. It also has a distinct coconut flavor that could overpower the flavor of the donuts. Opting for refined coconut oil can help mitigate its strong flavor while increasing its smoke point, but this is an expensive route to take so consider your clientele.
  • Avocado Oil: Both refined and unrefined avocado oil have smoke points high enough to be used for deep frying, making them technically suitable for frying donuts. However, given the premium cost of avocado oil, it’s not the most cost-effective choice for bulk frying. The expense may outweigh any potential benefits, especially when there are more affordable oils that perform just as well in the fryer.

When choosing an oil for your donut shop, let frying performance guide your decision. Most customers order donuts as a special treat rather than for health reasons, so it's best to prioritize flavor, smoke point, and cost when selecting your oil, rather than focusing solely on health aspects. To withstand the high temperatures required for deep frying, most oils must be refined to raise their smoke point, thus reducing their nutritional value.

Can You Fry Donuts in Lard or Beef Tallow?

Yes, lard and beef tallow have been used for centuries in donut frying, lending an old-fashioned taste. In fact, lard is the traditional frying medium to create authentic paczki and fastnacht. However, the cost is considerably higher to fry with animal fats than to use plant-derived oils. Lard has a smoke point of approximately 370 degrees Fahrenheit (188 degrees Celsius), while beef tallow boasts a smoke point of 400 degrees Fahrenheit (204 degrees Celsius). If you opt for lard or beef tallow, ensure they are properly rendered to maintain a neutral taste. It will also result in non-vegan or vegetarian donuts, which is something to keep in mind when choosing your target demographic.

What Temperature Should You Fry Donuts At?

The ideal temperature for frying donuts is between 350 and 375 degrees Fahrenheit (175 to 190 degrees Celsius). This temperature range ensures that the donuts cook quickly, becoming golden brown and crispy on the outside, while remaining soft and fluffy on the inside. It's important to maintain a consistent temperature throughout the frying process. If the oil is too hot, the donuts may brown too quickly on the outside while remaining raw inside. If the oil is too cool, the donuts will absorb more oil and become greasy. Using a thermometer to monitor the oil temperature can help ensure perfect frying results.

How Long Should You Fry Donuts For?

Donuts should typically be fried for 1 to 2 minutes on each side, depending on their size and thickness. The exact time may vary slightly, but you want the donuts to turn golden brown and crisp on the outside while remaining soft and fully cooked on the inside.


Donut shops can ensure consistent product quality by opting for a neutral oil with a high smoke point to fry their donuts. Each oil on our list is an excellent option for creating one of America’s most beloved baked goods, offering both versatility and stability at high temperatures. These oils help achieve the perfect crispness and flavor without imparting any unwanted tastes or aromas, allowing your signature creations to shine.
