When people buy a Blackstone griddle, the first questions are usually about heat, seasoning, and cooking performance. But once the excitement settles, a more important question comes up—what is the healthiest oil to use on a Blackstone griddle?
This isn’t just about taste. Cooking oils behave very differently at the high temperatures a flat-top griddle produces. Some oils stay stable and safe, while others break down, smoke excessively, and form harmful compounds. Choosing the right oil can make your cooking healthier and improve how your griddle performs long-term.
Let’s break this down in a simple, practical way—like someone who actually cooks on a Blackstone, not like a nutrition textbook.

Why “Healthy Oil” Matters More on a Blackstone – Healthiest Oil to Use on a Blackstone Griddle
A Blackstone griddle runs hotter than most home cookware. It’s designed for searing, frying, and fast cooking across a large steel surface. That heat is great for food—but tough on oils.
When an oil is heated beyond its smoke point, it:
- breaks down chemically
- releases free radicals
- loses nutritional value
- produces bitter flavors
- creates excess smoke
So the healthiest oil for a Blackstone must do two things:
- Stay stable at high heat
- Offer real nutritional benefits
That’s where avocado oil stands out.
Why Avocado Oil Is the Healthiest Choice
If you had to choose just one oil for health on a Blackstone griddle, avocado oil is the clear winner.
High Smoke Point = Less Breakdown
Refined avocado oil has a smoke point around 520°F (271°C). That’s higher than almost any common cooking oil. This means it stays stable even during intense searing, instead of burning and degrading.
Heart-Healthy Fats
Avocado oil is rich in monounsaturated fats, the same type found in olive oil. These fats are linked to:
- improved heart health
- lower LDL (“bad”) cholesterol
- better inflammation control
Natural Antioxidants
It also contains vitamin E, which helps fight oxidative stress created during cooking at high temperatures.
Neutral Flavor
Unlike some “healthy” oils, avocado oil doesn’t overpower food. Whether you’re cooking burgers, vegetables, eggs, or seafood, it stays in the background where it belongs.
That combination—high heat stability + real health benefits—is why avocado oil is often recommended by both chefs and health experts for griddle cooking.
Why Smoke Point Is a Health Issue (Not Just Smoke)
A lot of people think smoke is just annoying. But from a health perspective, smoke usually means the oil has already started breaking down.
When oils burn:
- beneficial fats degrade
- harmful compounds form
- food absorbs those breakdown products
On a Blackstone, where temperatures can spike quickly, oils with low smoke points simply aren’t ideal for everyday use—no matter how “healthy” they look on paper.
Other Healthy Oils That Work Well on a Blackstone
While avocado oil is the top choice, it’s not the only healthy option.
Grapeseed Oil
Grapeseed oil comes very close to avocado oil in performance. With a smoke point between 470–510°F, it handles griddle heat well and has a very light, neutral taste.
Nutritionally, it contains polyunsaturated fats and some vitamin E. Many people like how easily it spreads and how clean the surface feels after cooking with it.
Peanut Oil
Peanut oil has a smoke point around 450°F and is high in monounsaturated fats. It’s a solid choice for stir-fry style cooking or grilling where a slightly nutty flavor is welcome.
However, it’s not ideal if you cook for people with peanut allergies.
High-Oleic Sunflower Oil
This version of sunflower oil (not regular sunflower oil) is much more stable at high heat. It’s rich in monounsaturated fats and vitamin E, with a smoke point around 450°F.
It’s a good alternative if avocado oil isn’t available.
Refined Coconut Oil
Refined coconut oil has a higher smoke point than unrefined versions and is more stable at heat. It contains medium-chain triglycerides (MCTs), which some people prefer for energy metabolism.
That said, its flavor and high saturated fat content make it a more situational choice rather than an everyday oil for everyone.
Best Oil to Use on a Blackstone Griddle
Oils That Are Healthy—but Need Caution on a Blackstone
Some oils are nutritionally excellent but don’t always behave well at griddle temperatures.
Extra Virgin Olive Oil
EVOO is full of antioxidants and healthy fats—but its smoke point is around 375°F. On a Blackstone, that limit is reached quickly.
At high heat, olive oil:
- smokes heavily
- turns bitter
- loses health benefits
It’s better used on a Blackstone at lower temperatures or as a finishing oil after cooking.
Butter
Butter adds amazing flavor but burns very fast due to milk solids. Burnt butter isn’t just unpleasant—it also loses nutritional value.
A better option is ghee (clarified butter), which removes the milk solids and raises the smoke point to around 485°F. Ghee keeps the flavor without the burning issue.
Healthiest Oil for Seasoning vs Cooking
This is where many people get confused.
For Seasoning
Seasoning requires oil to polymerize at very high heat. Health matters, but heat stability matters more. Avocado oil, grapeseed oil, and canola oil all work well here.
Many people also prefer using a Blackstone-specific seasoning blend for the first seasoning because it’s designed to bond evenly and protect the steel long-term.
For Cooking
For daily cooking, avocado oil is still the healthiest and safest all-around choice. It stays stable, doesn’t overpower food, and doesn’t produce excessive smoke.
Does Oil Choice Affect Long-Term Health?
Yes—especially if you cook on a griddle often.
Repeatedly overheating unstable oils can lead to:
- increased intake of oxidized fats
- inflammation over time
- digestive discomfort
Choosing a stable oil like avocado oil reduces these risks while still allowing high-heat cooking.
Clean Surface = Healthier Cooking
Even the healthiest oil won’t help if old burnt residue stays on the griddle. Carbon buildup can re-burn and contaminate fresh food.
Keeping the surface clean after every cook:
- reduces burnt oil exposure
- keeps seasoning smooth
- improves flavor
A flat-top griddle scraper helps remove residue without damaging the steel.
Simple Rule for Healthy Blackstone Cooking
If you want a no-stress approach, follow this:
- High heat → avocado or grapeseed oil
- Medium heat → light olive oil or ghee
- Flavor finishing → butter or olive oil (low heat)
This keeps cooking safe, healthy, and enjoyable.

Final Thoughts
The healthiest oil to use on a Blackstone griddle is one that stays stable under heat and supports your health. Avocado oil checks every box—high smoke point, heart-healthy fats, antioxidants, and neutral flavor.
Other oils can work well too, but once you understand how heat affects oil chemistry, the choice becomes clear. Health on a Blackstone isn’t about avoiding oil—it’s about using the right oil the right way.
