Oils

One of the most frequent questions we get is how to use different oils and the differences between them. Are vegetable oils interchangeable? What's with the different grades of olive oil? Which oils are heart-healthy and which ones will send me to the hospital? These are all things we've wondered from time to time (okay, maybe not all of us...maybe there are some people who have bigger things on their minds than getting a giggle out of "extra virgin"), and we're here to answer them!

For what we're doing today, we're going to divide things up by vegetable oils, olive oils, and specialty oils.

Vegetable Oils



Canola oil: In terms of vegetable oils, this is your best and most versatile bet. It is a mild oil with little flavor, has a high smoke point (which makes it ideal for frying), and it has heart health benefits similar to olive oil. In terms of vegetable oil, I only buy canola oil.
Peanut oil: This is another versatile oil with a high smoke point. Thanks, Bethany, for reminding me about using it in stir-fry--its flavor and ability to handle high temperatures make it the perfect choice for stir-fries and other Asian cooking.

Okay Alternatives to Canola: Safflower and corn oil for deep frying, all-purpose cooking, and salad dressings. Sunflower for everything except deep frying.

Bad Alternatives to Canola: Palm oil, hydrogenated, and partially hydrogenated oils.

When Should I Use Vegetable Oil?

Use vegetable oil when a recipe calls for oil. Also, while olive oil can add great flavor to salad dressings, particularly strongly flavored ones, it can also congeal in the fridge which isn't great when you're in a hurry. Vegetable oil is a great option for most salad dressings.


Or maybe fry up some of your own homemade French Fries!



Olive Oils


Were you scared when you saw the sheer amount of olive oil in Sara's Chimichurri? Don't be! While olive oil is high in fat, there are a lot of great health benefits and it definitely has a place in a well-balanced diet. It's one of the few foods that contains "good" cholesterol, which helps control "bad" cholesterol. While all olive oil contains antioxidants, extra-virgin olive oil contains the highest levels of antioxidants, which are beneficial in fighting both long- and short-term diseases.

But what's with all the virgin talk? What does that mean?

Extra-Virgin: This is from the first pressing of the olives and hasn't been treated or chemically refined. Like I said, this contains the highest levels of antioxidants and has the purest flavor. Save the extra-virgin for when taste matters--chimichurri, salad dressings, drizzling onto sandwiches. It's the best all-around olive oil and a lot of people prefer to use it exclusively.

Virgin: From the second pressing. This is good for things like pastas or browning meat and onions for soups and sauces.

Pure: More processed and refined. This oil may have an offensively strong flavor or odor.

Light and Extra Light: People sometimes get the wrong idea thinking that "light" olive oil means it's lower in fat or calories. Think of "light" as "refined". Extra light olive oil is so refined that it hardly has any flavor or color. In terms of health benefits, the lighter you go the less you get. But if you'd like to use an olive oil but don't want the flavor, it may be a good option for you.

So with all you can do with olive oil, what shouldn't you use it for? Well, it's quite heavy and it has a low smoke point, so deep frying is a bad idea. Because of it's strong flavor, it shouldn't be used in cakes and cookies unless the recipe specifically calls for it. And, like I said, it will solidify in the refrigerator, but that doesn't mean you can't use it in salad dressing or marinades, it just means that you'll need to let it reach room temperature before serving it.

Try olive oil in Sara's Chimichurri


or the dressing for Sara's Steak and Mango salad.

Feeling the urge to roast some garlic


or some tomatoes?


Specialty Oil(s)

So we really haven't ventured too far into the realms of specialty oils, but I will say that most of them have to do with some kind of regional food, tend to be quite strongly flavored and should be used in moderation. This includes things like chili oil and sesame oil. Luckily, we have lots of recipes that use sesame oil, lest you think that we're being unfair in our practices toward specialty oils. Things like the Steak and Mango Salad I mentioned earlier and Sara's Thai Beef Skewers.


So...have you changed what oils you use based on their health benefits? Is the flavor of olive oil too strong for you? Tried any wild and crazy specialty oils? Have any ideas on how we could implement more of them?

I always use peanut oil when I'm making a stir-fry. I find that it really makes a big difference and gives that "authentic" Chinese-restaurant flavor to the meal.

Also, I have to speak up in coconut oil's defense! The saturated fats in coconut oil are medium-chain fatty acids which are digested and metabolized differently than the more common long-chain fatty acids. Coconut oil is an excellent source of energy and doesn't increase the risk of heart disease like other saturated fats do.

Plus, popcorn popped in coconut oil is really tasty. ;-)

I've been loving your site since my friend Brenda from Secret Agent Josephine introduced me to it! I can't wait to try making your homemade hot pockets and the salted caramel cupcakes.

Kate said...

Bethany, you're totally right about peanut oil and stir-fry! Thanks for reminding me--I'll update the post now! :)

Abby said...

that's good to know about the hydrogenated oils.... What about corn oil? My mom always had corn oil in her cabinet, but I tend to buy canola oil.

Kara said...

I'm so glad you posted about this. My only question is, what about the bottles of oil that just say, Pure Vegetable Oil? Is that any different than the Canola?

Jenny in Utah said...

Thanks for all the info. I served a mission in Spain and have been "drinking" olive oil ever since. Once you acquire the taste of it there is no going back. I drizzle it on almost everything that needs a drizzle anymore! I am glad to be reminded of all the good it does!

Kate said...

Ahhh! I had corn in there, I swear! You guys, I think I'm losing my mind.

Anyway, corn oil is okay; it's got a high smoke point a neutral flavor, and it's CHEAP, but it doesn't have the same cholesterol-lowering properties that canola oil has.

Kara, it's probably some compound of different vegetable oils. Honestly, I don't think the kind of oil in cooking spray matters because you're getting SO little of it (unless you're going for the flavor of olive oil).

Steph said...

We recently switched to canola oil (instead of plain vegetable) for all our regular cooking, and there really is no difference in taste. So yeah for taking a small step to be healthier! And with all the fresh veggies we've been picking up at the farmers market, we're burning through our olive oil and kosher salt :)

As far as other oils go, I've used peanut and sesame in asian foods, and they're yummy!

Natalie said...

What about extra light olive oil? I started out with that when I started switching over to cooking with olive oil because I wanted a really mild flavor. Other than that, I don't know much about it. I would love any info anyone has.

Kate said...

Extra light is similar to pure; it's on the more processed end of things. It's definitely good if you're after a mild flavor, but it doesn't contain as many of the health benefits or the more distinct flavor of the extra-virgin olive oil.

Sara @ Our Best Bites said...

Natalie- extra light olive oil is heavily refined. Basically the more "light" is is just means the more refined it is. So much that it hardly has any flavor or color. The term itself isn't really regulated so there could be other things in there as well. You lose a lot of the health benefits the lighter you go.

Sara @ Our Best Bites said...

Ha Kate- looks like we were posting at the same time!

Les@SpillingBuckets said...

I use mostly olive oil, either virgin or extra virgin. I do have a small bottle of canola though, and use sesame oil for stir fry and other Asian meals.

Now if you could do a similar post on vinegar (red wine, white wine, distilled, white, ... )that would be great. ;-)

Kelly said...

what about grapeseed oil? It's a great alternative to canola oil.

CaSaundraLeigh said...

This was really helpful--I had just been pondering which oil I should buy next--I think I'll shoot for canola! Thanks :-)

Christina said...

Thank you! That was very helpful. I could sure use one on the "creams". Half and Half, Whipping cream, Heavy Cream, yadda yadda yadda. I never know what I can use to substitute, etc. But maybe I'm the only one not so bright:0)

Victoria said...

I do oil EXACTLY like you do... I do love to infuse olive oil for different purposes, such as garlic and rosemary for oven-roasting potatoes. I also like to use the oil that my sun-dried tomatoes are packed in as the base for yummy pasta.

Andrea said...

A couple of cooments on oils...

2 tablespoons a day of flax seed oil has HUGE health benifits. Far to many for me to go into here but google it and you will see. I will say that it is not the same to take it in pill form because you most likely will not be getting enough (unless you want to swallow a handful of pills) and because it can go rancid and you wouldn't know it.

Also, truffle oil is so delicious and is a more affordable way to impart that delicious truffle flavor into foods. Use it when you are done cooking whatever you are going to put it in. My favorite thing to add it to is egg salad!

Ashley said...

Thanks so much for all these great tips! Yours is my FAVORITE food blog!

Jennifer said...

My biggest question is, is there a specific brand of olive oil that is better than others? I always hear the term "good olive oil" but I have no idea what that means.

Kate @ Our Best Bites said...

Jennifer, that's a great question. You know, you can find some really high-end, very expensive olive oils, particularly in specialty shops/Williams-Sonoma/Sur la Table. Being the cheapskate that I am, I've never bought them, so I can't attest to their fabulousness. I do know that I've had great luck with moderately priced extra virgin olive oil that just comes from the grocery store. I'm sure there are olive oil officionados out there who are appalled by that attitude, and believe me, I'd LOVE to have the luxury to taste and experiment with different olive oils, but I've found that to be the safest route. Hope that helps a little! :)

Braden and Cheri said...

You might be inclined to do a little post about hydrogenated and partially hydrogenated oils. I don't think enough people out there realize how dangerous those oils are. It might be worth educating your readers...and encouraging them to make their own food.

Also, though olive oil does solidify in the fridge, it should not deter people from using it as it doesn't take too long to "melt" and you could dip the bottle in warm water and it will return to liquid form very quickly.

Thanks for all this great information!
