Shortening For Vegetable Oil

Okay, let’s talk about the greasy, glorious underdog of the baking world. You know that moment when a recipe calls for shortening, and you stare into your pantry, holding a bottle of vegetable oil like a lost tourist holding a map upside down? You wonder, “Can I just… swap them?” Spoiler alert: You can, but the results might be hilariously tragic if you don’t know what you’re doing.

First, a brutal truth: shortening is a solid block of pure, hydrogenated fat. Vegetable oil is a liquid. They are not twins separated at birth; they’re more like distant cousins who only show up for the holidays and argue about politics. Shortening is the muscle that holds your pie crust together, while oil is the lazy pool float that lets everything slide around.

If you try to swap oil directly for shortening in a cookie recipe, you’ll get puddles. Not cookies, not even pancakes—just greasy, flat, sad puddles that taste like regret and burnt butter. The texture collapses because oil adds moisture, but zero structure. It’s like building a house out of pudding.

But here’s the surprising part: you actually can replace shortening with vegetable oil—if you’re willing to do some math and accept a little chaos. The general rule is to use about three-quarters of the amount of oil as you would shortening. So, one cup of shortening equals ¾ cup of oil. And you’ll need to add a little extra structure, usually an egg or a splash of milk.

Why would anyone do this?

Good question, imaginary café friend! Maybe you’re vegan, maybe you ran out of shortening at 11 PM, or maybe you just hate the way shortening feels—like a slippery, waxy alien. Vegetable oil is neutral, clean, and way less creepy. It also makes things stay softer longer, which is a win for brownies that refuse to go stale.

However, there’s a catch that’ll make you laugh and cry: oil can’t trap air like shortening can. Shortening is a solid fat that grabs tiny air bubbles during creaming, giving you light, fluffy cakes. Oil just sits there, being smooth and useless at aerating. Your cake will be denser, almost like a really tasty, moist brick.

So, when should you make the swap? For quick breads, muffins, and brownies—go for it! These recipes typically don’t rely on creaming for air. But for flaky pie crusts, flaky biscuits, or any kind of pastry that needs layers of solid fat, do not even think about reaching for that oil bottle. You’ll get a tough, greasy sheet that looks like a geological disaster.

The “Five-Second” Shortcut (Yes, You Can!)

Here’s a mind-bender: you can actually make your own shortening at home by mixing vegetable oil with a little bit of melted, solidified coconut oil or butter. Chill it, and boom—solid fat, but with the heart of a vegetable oil. It’s like a fat cyborg. Just don’t tell your health-conscious friends; they’ll stage an intervention.

Another wild fact: vegetable oil was originally a marketing gimmick. In the early 1900s, Procter & Gamble invented Crisco as a cheaper, shelf-stable alternative to lard. They literally told housewives, “It’s healthier because it’s not from a pig.” Which is technically true, but it’s also hydrogenated, which means it’s basically plasticized fat. Still, it’s cheaper than therapy.

Now, if you really want to get technical (and annoy everyone at dinner), know this: oil is 100% fat, while shortening is usually 100% fat with added emulsifiers to mimic butter’s behavior. So when you swap, you’re losing those emulsifiers that make cake batter silky. Your cake might weep a little. Like, literally, it might get a sweat on.

Here’s a pro tip that sounds insane but works: freeze your vegetable oil before using it as a shortening substitute. Not fully solid, but get it thick like honey. It’ll behave closer to the real thing, letting you fake your way through a pastry crust. You’ll feel like a mad scientist, but science is messy. And delicious.

In the end, the great shortening-for-oil swap is about managing expectations. Don’t expect a towering angel food cake from a bottle of canola oil—you’ll get a mini-muffin. Don’t expect a flaky croissant from olive oil—you’ll get a cracker with anxiety. But for everyday baking? It’s a perfectly imperfect solution.

So go ahead. Be reckless. Swap that shortening for oil when the craving hits. Your cookies might be flat, your pie crust might be tough, but you’ll have a story to tell. And if all else fails, just call them “rustic.” Nobody can argue with rustic. Just don’t tell them you used oil instead of shortening—that’s a need-to-know secret, and they don’t need to know.
