Soybean oil is a hugely popular vegetable oil extracted from soybeans, while butter is a dairy product that’s been around forever. So, which one is truly the best?
In this article, I’ll explain the differences between soybean oil vs butter, including how they taste, their nutritional value, and how well they work in cooking to determine which one deserves a spot in your kitchen. Let’s go!

Differences between soybean oil and butter
Soybean oil and butter are two popular oils/fats with distinct characteristics and extraction processes.
Soybean oil is made by extracting oil from soybeans through a refining process involving crushing, pressing, or solvent extraction, while butter is made by churning cream, separating the fat from the liquid, and solidifying it.
The main difference lies in their composition. Soybean oil is a plant-based fat with a higher proportion of unsaturated fats, while butter is an animal-based fat that is higher in saturated fats. These distinctions affect their taste, texture, and cooking properties, making each suitable for different situations…
Baking and cooking with soybean oil vs butter
Soybean oil is a versatile cooking oil that has a high smoke point, meaning it can handle higher temperatures without breaking down. This makes it ideal for frying, sautéing, and stir-frying. Its neutral flavor allows it to complement a wide range of dishes without overpowering the other ingredients. It’s also a common ingredient in salad dressings or mayonnaise.
On the other hand, butter brings a rich and distinct flavor to dishes. It works wonderfully in baking, giving pastries and cakes a delicious taste and tender texture. Butter is also perfect for pan-frying, basting meats, and creating creamy sauces. However, due to its lower smoke point compared to soybean oil, it’s best to use butter for low to medium-heat cooking.
Can soybean oil and butter be substituted for each other?
While soybean oil and butter have different characteristics, they can often be substituted for each other depending on the recipe. When replacing butter with soybean oil, a general guideline is to use 3/4 cup of oil for every 1 cup of butter. However, it’s important to note that the texture and taste of the final dish may vary. In recipes where butter is essential for its distinct flavor, such as cookies or buttercream frosting, it’s best to stick with butter. Conversely, in recipes that require high-heat cooking or a neutral taste profile, soybean oil can be a suitable substitute.
Nutrition: Soybean oil vs butter
Soybean oil is primarily a source of unsaturated fats, including both polyunsaturated fats (such as omega-6 fatty acids) and monounsaturated fats. These fats are considered healthier options compared to saturated fats. Soybean oil also contains vitamin E, which acts as an antioxidant in the body.
On the other hand, butter is predominantly made up of saturated fats, which are known to contribute to high cholesterol levels when consumed in excess. It also contains small amounts of vitamins A, D, E, and K.
In terms of calorie content, soybean oil is a bit higher than butter, with around 120 calories per tablespoon.
| Per tablespoon (15mL) | Soybean oil | Butter |
| Calories | 120 | 102 |
| Polyunsaturated | 7.9 g | 0.4 |
| Monounsaturated | 3.1 g | 3.0 g |
| Saturated | 2.1 g | 7.3 g |
| Trans | 0.1 g | 0.5 g |
| Total Fat | 13.6 g | 14.2 g |
| Cholesterol | 0 | 30.5 mg |

How to store soybean oil and butter
Proper storage is crucial to maintain the quality and shelf life of soybean oil and butter. Soybean oil should be stored in a cool, dark place, away from direct sunlight and heat sources. If you don’t use oil very often, I would keep it in the fridge to keep it fresh for longer. Sealing it tightly after each use helps prevent oxidation and rancidity.
Butter should be kept refrigerated in an airtight container to preserve its freshness. For longer-term storage, it can be frozen to retain its quality. However, always check for any changes in color, smell, or taste before using stored soybean oil or butter.
Soybean oil vs butter: The ultimate verdict
Ultimately, the choice between soybean oil and butter depends on your personal preferences, dietary needs, and the specific dish you’re preparing.
If you prioritize a plant-based option with a neutral flavor and a higher smoke point for various cooking techniques (everything from frying to salad dressings), soybean oil shines. On the other hand, if you seek a rich taste and a versatile ingredient for baking and flavoring, butter takes the crown. Butter is one of the fats I always keep in my kitchen (in the fridge!). I tend to prefer its rich taste for baking and making pasta sauces and more.
FAQs
The better choice between butter and soybean oil depends on personal preferences, dietary considerations, and the specific cooking application. While butter offers a rich flavor and is versatile in baking and flavoring, soybean oil’s neutral taste and higher smoke point make it ideal for high-heat cooking methods.
In general, oils like soybean, olive, and safflower oil, with their lower saturated fat content and higher unsaturated fat profile, can be a healthier option when consumed in moderation. Stick to moderate butter consumption due to its higher saturated fat content.
Soybean oil can be a part of a healthy diet when consumed in moderation, as it contains unsaturated fats, including beneficial omega-3 and omega-6 fatty acids.
