How to choose a deep fryer
Updated June 2026Independently researchedNo paid placement.
The best deep fryer for 2026 comes down to how much you cook, what you fry, and how much cleanup you’ll tolerate. Look for a model with an adjustable thermostat (a wide range gives you control), a large enough basket for your batch sizes, and dishwasher-safe parts that make oil changes less of a chore. Dual-basket machines are great for cooking different foods at once, and a high-quality oil filtration system can extend the life of your oil significantly.
What kind of oil should you use for deep frying?
Choosing the right oil is just as important as the fryer itself. Oils with a high smoke point, like peanut, canola, sunflower, or avocado, hold up well to the high temperatures frying requires without breaking down into off-flavors or smoke. Stay away from extra-virgin olive oil or butter, which burn quickly and will ruin your food. Many home cooks prefer peanut oil for its neutral taste and ability to handle repeated use. If you have nut allergies, canola or vegetable oil are safe alternatives. The oil you pick also affects how often you need to change it: cleaner oils with fewer impurities tend to last longer. Always check the fryer’s manual for recommended oil types and maximum temperature limits.
Electric vs. propane deep fryers: which one is right for you?
Electric deep fryers are the most common choice for home kitchens. They plug into a standard outlet, heat evenly thanks to a built-in element, and often include thermostats that keep a steady temperature. They’re quieter, easier to place on a countertop, and generally safer for indoor use. Most should never be used outdoors unless specifically rated for it. Propane or outdoor deep fryers, on the other hand, are built for high-volume frying, think turkey, large batches of fries, or whole fish. They get hotter faster and can handle bigger loads, but they require a dedicated outdoor space, proper ventilation, and careful monitoring because the temperature can swing more wildly. If you only fry a few times a month indoors, an electric fryer is the more practical, safer option.
How much oil capacity do you really need?
Capacity is about matching the fryer to your household. A 3- to 4-quart fryer is fine for a couple or small family, enough for a batch of chicken wings or a few servings of fries. For families of four or more, or if you regularly entertain, look for a 6- to 8-quart model. That size can handle a whole chicken or a large batch of seafood without dropping the oil temperature too much. Keep in mind that the oil capacity is not the same as the basket capacity, you never fill the fryer to the brim. A good rule of thumb is that the food you add should not exceed about half the oil volume, or the temperature will crash and you’ll end up with soggy results. Also, larger fryers take more oil to fill, which means higher upfront cost and more oil to store.
What features make cleaning a deep fryer easier?
Cleaning is the biggest downside of any deep fryer, so look for design choices that simplify the chore. Fryers with a nonstick coating on the interior pot make wiping out residue much faster. Removable oil containers, some models let you lift out the entire pot, are far easier to wash than one-piece units. Dishwasher-safe parts are a huge bonus because they save you from scrubbing by hand. Another smart feature is an oil filtration or draining system that lets you pour out used oil without tipping a heavy, hot pot. Some models have a spigot at the bottom for draining, while others have a pump that filters and stores oil for reuse. Anything that keeps hot oil contained and off your countertop is worth the extra money. If you fry often, a model with a cool-touch exterior and a lid that locks for storage will also reduce mess.
Digital vs. manual controls: which is better for frying?
Digital controls offer precise temperature settings and often a timer that beeps when your food is done. They remove guesswork, which is helpful if you’re trying to replicate a recipe exactly or you tend to get distracted. Many digital fryers also include preset buttons for common foods like fries, chicken, or fish, though these presets vary in reliability. Manual controls, usually a simple dial thermostat, are more straightforward and less prone to electronic failure. They heat up quickly, and you can adjust the temperature by feel or with an instant-read thermometer. The trade-off is that you have to watch the clock yourself and keep an eye on the oil temperature if it drifts. For most home cooks, a digital model with a clear readout and a countdown timer adds convenience without sacrificing control. Just be aware that digital models tend to cost a little more.
Frequently asked questions
Can you reuse deep frying oil?
Yes, you can reuse oil several times if you strain it after each use to remove food particles. Store it in a cool, dark place and discard it once it becomes dark, smoky, or develops a rancid smell. Oils with high smoke points, like peanut or canola, tend to last longer.
How do you clean a deep fryer properly?
Start by letting the oil cool completely, never rush this step. Pour the oil through a fine-mesh strainer or cheesecloth into a storage container. Wipe out the interior with paper towels to remove residue, then wash removable parts in hot, soapy water (or the dishwasher if they’re safe). Dry everything thoroughly before reassembling.
What is the best temperature for deep frying?
Most foods fry best between 350°F and 375°F (175–190°C). Lower temperatures (around 325°F) work for thicker cuts like chicken thighs that need more time to cook through, while 375°F is ideal for crispy items like french fries or onion rings. Always check your recipe for guidance.
Do you have to preheat the oil before adding food?
Absolutely. Adding food to oil that isn’t hot enough will cause the food to absorb too much oil and turn greasy. Most deep fryers have a ready light or indicator that tells you when the oil has reached the set temperature. Give it a few extra minutes to stabilize before you drop in the first batch.
How often should you change the oil in a deep fryer?
It depends on how often you fry and what you fry. If you use the fryer once a week for breaded foods, you might change the oil every 8–10 uses. For frequent frying or foods with heavy batter (which leaves more debris), change it after 4–6 uses. When the oil starts smoking at normal frying temperatures, it’s time to replace it.
Can you use a deep fryer outdoors?
Only if the fryer is specifically rated for outdoor use. Most electric deep fryers are designed for indoor use and should not be exposed to rain, wind, or unstable surfaces. Propane outdoor fryers are meant for patios or backyards and must be kept away from flammable structures. Always follow the manufacturer’s safety instructions.
