You’ve been there. It’s 7:00 AM, you’re running late, and you just want a piece of toast. You grab the butter from the fridge, press the knife down, and—crunch. The bread is ruined. It’s torn into a million pieces because cold butter has the structural integrity of a brick. This is exactly why spreadable butter with olive oil exists, but most people think it’s just a lazy shortcut. It isn't. It’s a specific culinary tool that balances fat profiles while solving the "cold-start" problem of breakfast.
Honestly, the chemistry is what makes it cool. Pure butter is mostly saturated fat. Those molecules pack together tightly at low temperatures, which is why a stick of Kerrygold feels like granite when it's chilled. Olive oil, however, is loaded with monounsaturated fats. These stay liquid even when things get cold. When you blend them, you're essentially lowering the melting point of the mixture.
It’s physics you can eat.
The Reality of What’s in the Tub
Don't let the marketing fool you into thinking every tub is the same. If you look at a brand like Land O'Lakes or Bertolli, the ingredient lists tell different stories. Some are mostly butter with a splash of oil for "vibes," while others are a 60/40 split. You want to look for the ones where cream is the first ingredient, followed by olive oil and sea salt.
If you see "plant oils" or "vegetable oil blend" listed before olive oil, you're basically buying margarine with a fancy hat on. True spreadable butter with olive oil should taste like dairy first, with a peppery or fruity finish from the olives.
Why the "Healthy" Label is Complicated
We’ve been told for decades that saturated fat is the enemy, though modern nutrition science—like the stuff coming out of the Harvard T.H. Chan School of Public Health—suggests it’s more about the replacement. If you swap some saturated animal fat for monounsaturated plant fat, your LDL (the "bad" cholesterol) might drop.
But let's be real. It’s still butter. It’s still calorie-dense.
The real health win here isn't that it's a "superfood." It's that you tend to use less. Because it spreads thinly and evenly, you don't end up with those massive, un-melted chunks of butter hiding in the crevices of your English muffin. Those chunks add up to an extra 50 calories you didn't even taste.

Cooking with Spreadable Butter with Olive Oil
Can you bake with it? Sorta. But you shouldn't.
Baking is a game of ratios. If a recipe for chocolate chip cookies calls for "softened butter," it’s counting on the specific water content and melting point of dairy fat to create structure. When you introduce olive oil into that mix, your cookies will likely spread too much and turn into oily puddles.
However, for sautéing? It’s a game changer.
Pure butter has a low smoke point because the milk solids burn quickly. Olive oil has a higher smoke point. When they’re blended in a spreadable butter with olive oil format, you get the flavor of the butter with a slightly higher heat tolerance. It’s perfect for pan-searing a piece of tilapia or getting that golden crust on a grilled cheese.
I’ve found that using it for scrambled eggs is the "pro move." The olive oil prevents the butter from browning too fast, so your eggs stay bright yellow and creamy instead of picking up that burnt-nutty taste that can sometimes overwhelm delicate proteins.
The DIY vs. Store-Bought Debate
You can actually make this at home in about five minutes. It saves money and you get to control the quality of the oil. Most commercial brands use refined olive oil because it’s shelf-stable and has a neutral flavor. If you make it yourself, you can use a high-end Extra Virgin Olive Oil (EVOO) from a specific region, like a spicy Sicilian oil or a grassy Spanish variety.
How to do it (The 1:1 Method):
Take two sticks of unsalted, grass-fed butter and let them get completely soft at room temperature. Don't melt them in the microwave; you'll break the emulsion. Put them in a food processor or a stand mixer with about 2/3 cup of good olive oil and a pinch of flaky sea salt. Whip it until it looks like soft-serve ice cream.

Transfer it to a glass jar and stick it in the fridge.
It stays soft. Every single time.
The downside of the DIY version is that it can occasionally separate if your kitchen is too warm during the mixing process. If it looks "sweaty," just give it another quick stir. Store-bought versions use emulsifiers like soy lecithin to prevent this, which isn't the end of the world, but it’s one more processed ingredient in your body.
What Most People Get Wrong About Storage
People treat this stuff like it’s invincible because of the oil content. It's not.
Butter can sit on the counter in a butter bell for a few days, but spreadable butter with olive oil should almost always stay in the fridge. Olive oil is sensitive to light and heat; it goes rancid faster than saturated fats do. If you leave your tub out in the sun or near the stove, that oil is going to start tasting like old cardboard within 48 hours.
Also, watch out for "crumb contamination." Since the butter is soft, it’s easy to double-dip your knife. If you leave breadcrumbs or jam in the tub, you’re introducing moisture and bacteria that will mold way faster than the fats will spoil.
Flavor Profiles and Pairing
Not all olive oils play nice with dairy. Some high-polyphenol oils are incredibly bitter. When you mix that with the sweetness of cream, the result can be... weird.

If you're buying at the store:
- Lurpak is a gold standard for many because it uses a lactic culture that gives it a slight tang.
- Kerrygold Spreadable uses Irish butter, which is naturally higher in beta-carotene (that's why it's so yellow).
- Private labels (Trader Joe’s, etc.) are often surprisingly good but check the oil-to-butter ratio.
If you’re a fan of sourdough, the slight bitterness of the olive oil in the blend actually complements the fermentation of the bread better than plain butter does. It adds a layer of complexity that makes a simple snack feel like a $14 appetizer at a bistro.
The Sustainability Angle
There's a quiet conversation happening about the environmental footprint of dairy versus vegetable oils. It’s no secret that cattle farming is resource-heavy. By shifting a portion of your "butter budget" to olive oil, you’re technically reducing the demand for dairy.
Olive groves are often carbon sinks, especially in Mediterranean regions where the trees have been standing for centuries. It’s a small tweak, sure. But if you’re trying to move toward a more "planetary health" diet—as suggested by the EAT-Lancet Commission—this blend is a logical stepping stone between full dairy and vegan alternatives that are often highly processed with coconut or palm oils.
Why It’s Not Just "Margarine"
Let’s clear the air. Margarine was originally made from beef tallow but evolved into a cocktail of hydrogenated vegetable oils. The "spreadable" products from the 90s were often full of trans fats.
Spreadable butter with olive oil is different because it’s a whole-food hybrid. You’re taking two ancient ingredients—churned cream and pressed olives—and just putting them in the same room. No hydrogenation. No weird chemical restructuring. Just a physical blend. That distinction matters for both flavor and how your body processes the fats.
Practical Steps for Your Next Grocery Run
If you're ready to make the switch or just want to upgrade your current tub, here is how to handle it like an expert.
- Read the label back-to-front: If water is the second or third ingredient, you're paying for "filler" that makes the butter spreadable but will make your toast soggy. Avoid high water content.
- Check the "Extra Virgin" claim: Many brands just say "with Olive Oil." That usually means refined oil. If it specifically says "Extra Virgin," the flavor will be more robust, but the price point will reflect it.
- Temperature control: When using it for toast, let the toast sit for exactly 10 seconds before spreading. This allows the steam to dissipate so the bread stays crispy, but the residual heat is still enough to liquefy the spreadable butter instantly.
- Small batches: If you're making it at home, don't make a quart of it. Make enough for one week. This keeps the olive oil fresh and prevents the fats from picking up "fridge smells" like onions or old leftovers.
- Salt levels: Most spreadable blends are salted to help with preservation. If you’re on a low-sodium diet, look specifically for "Unsalted Spreadable," though they are harder to find because the salt helps the oil and butter stay integrated.
Whether you're doing it for the heart-healthy fats or just because you're tired of destroying your sourdough every morning, switching to a high-quality blend is one of those small kitchen upgrades that actually pays off daily. It’s the sweet spot between culinary tradition and modern convenience.
