Best Oil For Donut Frying

So, you want to fry donuts. Good for you. You’ve already won half the battle just by deciding to fill your kitchen with that glorious, sugary smell.

But hold your horses—or your dough—because choosing the wrong oil is a disaster waiting to happen. It’s the difference between a pillow of joy and a greasy, sad sponge.

Let’s be real: you want a donut with a crispy, golden crust and a fluffy, tender inside. The oil is your unsung hero here.

The Heavy Hitters: Your Best Friends

Neutral oils with high smoke points are what you need. Think canola, vegetable, or peanut oil. They won’t fight with your donut’s delicate flavor.

Peanut oil is a rockstar. It has a high smoke point (around 450°F) and adds a subtle, nutty warmth that makes your donut taste like it came from a fairground. Just check for allergies first, yeah?

Canola oil is the reliable friend. It’s cheap, neutral, and does the job without any drama. Smoke point is around 400°F, which is perfect for that 350-375°F sweet spot.

Vegetable oil is basically the same story—a blend of soybean and other oils. It’s fine, it works, but it’s not exciting.

The Coconut Oil Wildcard

Okay, hear me out: refined coconut oil. It has a high smoke point (around 400°F) and gives donuts this insane, flaky crust. The flavor? Barely there if you use refined.

But unrefined coconut oil? That’s a tropical vacation in a donut. If you’re into that, go for it. I’m not judging your beachy dreams.

Oils to Absolutely Avoid (Seriously, Don’t)

Extra virgin olive oil? No. It burns at around 350°F, tastes like a salad, and makes your donuts sad. You’ll regret it.

Butter or lard? They burn fast (smoke point around 350°F or lower) and leave a greasy, heavy mess. Unless you want a smoke alarm serenade, skip them.

Flaxseed, walnut, or hemp oil. These are for salads, not frying. They’ll smoke, taste weird, and cost you a fortune. Don’t be that person.

The Science-y Bit (Don’t Worry, It’s Painless)

Why smoke point matters? Because if your oil smokes, it breaks down and makes your donuts taste like burnt regret. And it releases nasty compounds.

You want the oil to stay between 350°F and 375°F. Too low, and your donuts soak up oil like a sponge. Too high, and they burn before the inside cooks.

The Best Type Of Oil To Use When Frying Donuts At Home

Get a deep-fry thermometer. Yes, you can guess, but you’re better than that. You’re a donut artist now.

A Quick Tip on Reusing Oil

You can reuse frying oil, but not endlessly. After one donut batch, strain it through a fine mesh sieve or cheesecloth into a clean jar.

Store it in a cool, dark place. Use it once or twice more, then pitch it. If it smells off or gets foamy, toss it. Your taste buds will thank you.

What About Shortening (The Old-School Choice)?

Vegetable shortening like Crisco has a cult following. It’s pure fat—no water, no milk solids—so it gives a super-crisp, almost lacy crust. Smoke point is around 360-370°F.

Downside? It’s processed and can feel heavy. But for a classic, old-fashioned cake donut? It’s a winner. It’s a nostalgia bomb.

The Frying Method Matters Too

Use a heavy pot or a Dutch oven. A deep, wide pot holds heat better and makes splashes less likely. That’s safety and science in one sentence.

Don’t crowd the donuts. They need space to puff up and dance. If you stuff them in, the temperature drops, and you get greasy blobs. No one wants that.

Let the donuts cool on a wire rack over a baking sheet. Not paper towels—those trap steam and make the bottoms soggy. You’re not making a diaper.

So, What’s the Verdict?

Peanut oil is my personal MVP. It’s flavor-forward, handles high heat like a champ, and makes your kitchen smell like a state fair. Canola is the safe bet for budget and neutrality.

Refined coconut oil is the hipster choice that actually delivers. Try it once and you’ll be hooked.

Whatever you pick, just don’t use olive oil. I’m begging you. Your donuts deserve better, and so does your fire alarm.

Now go forth and fry. I’ll be waiting here, mentally stealing one of your donuts. You’re welcome.
