After 8 years of daily Blackstone use, here’s what I’ve learned: Your outdoor griddle is more than just a cooking surface; it’s the heart of backyard feasts and family gatherings. To unlock its full potential and ensure years of flawless performance, proper seasoning is absolutely essential. But with countless oils available, choosing the right one can feel overwhelming.
This comprehensive guide compares the top 7 griddle seasoning oils, breaking down their smoke points, polymerization properties, and cost-effectiveness. Whether you’re seasoning a brand-new Blackstone griddle or maintaining your well-loved cast iron surface, you’ll discover exactly which oil delivers the best results for your specific needs and budget.
Why Seasoning Your Outdoor Griddle is Essential
Seasoning transforms your bare metal griddle into a high-performance cooking powerhouse through a fascinating process called polymerization. Here’s why it’s absolutely crucial:
- Creates a Natural Non-Stick Surface: When oils are heated beyond their smoke point, fatty acids break down and form polymer chains that bond permanently to the metal, creating that coveted slick surface.
- Prevents Rust and Corrosion: A properly seasoned surface forms an impenetrable barrier against moisture, the leading cause of rust on cast iron and carbon steel griddles.
- Enhances Food Flavor: Over time, the seasoned layer develops complex flavors that subtly enhance everything you cook.
- Extends Griddle Lifespan: The polymerized coating shields the metal from acidic foods and harsh weather conditions, significantly extending your griddle’s life.
The Science Behind Seasoning: When heated above their smoke point, oil molecules undergo polymerization—they link together to form a tough, plastic-like coating that’s chemically bonded to the metal. This isn’t just oil sitting on the surface; it’s a permanent transformation that creates the non-stick properties you need.
What Makes the Perfect Griddle Seasoning Oil?
Not all oils are created equal for seasoning. Here are the critical factors that separate excellent oils from poor choices:
Smoke Point: The Temperature Sweet Spot
The smoke point is when oil begins to break down and smoke. For effective seasoning, you must heat oil beyond its smoke point to trigger polymerization. Oils with smoke points between 400-450°F are ideal—high enough to polymerize effectively, but not so high that you can’t reach the necessary temperatures on most griddles.
Fatty Acid Composition: The Foundation of Durability
The type of fats in your oil determines how well it polymerizes:
- Polyunsaturated Fats (Best for Seasoning): Multiple double bonds make these fats polymerize quickly and create the hardest, most durable seasoning layers. Found in grapeseed, flaxseed, and soybean oils.
- Monounsaturated Fats (Good for Seasoning): Single double bonds polymerize well and create stable layers. Found in avocado and olive oils.
- Saturated Fats (Poor for Seasoning): No double bonds mean minimal polymerization. These oils work better for maintenance than building initial seasoning layers. Found in coconut oil and animal fats.
Cost-Effectiveness and Availability
Initial seasoning requires multiple coats and generous amounts of oil. Consider both upfront costs and long-term value when selecting your oil.
Flavor Impact
While polymerized layers are largely flavorless, some oils can impart subtle tastes, especially during maintenance applications. Neutral oils are generally preferred for versatility.
Top 7 Griddle Seasoning Oils: Detailed Comparison
Here’s our comprehensive analysis of the most popular griddle seasoning oils, ranked by overall performance:
1. Grapeseed Oil (Best Overall)
The gold standard for serious griddle enthusiasts seeking maximum durability.

- Fat Composition: 28% polyunsaturated, 63% monounsaturated, 7% saturated
- Pros: Extremely affordable and widely available. Good polymerization properties. Neutral flavor. Reliable, consistent results.
- Cons: Slightly less durable than oils higher in polyunsaturated fats. May require more frequent touch-ups.
- Best For: Budget-conscious users, beginners, and frequent re-seasoning. Excellent all-around choice.
3. Crisco Vegetable Shortening (Most Traditional)
The time-tested favorite of cast iron and griddle veterans.
- Smoke Point: 450°F
- Fat Composition: Balanced blend of hydrogenated soybean and palm oils
- Pros: Decades of proven results. Easy to apply evenly as a solid. High smoke point. Creates smooth, slick surfaces. Very affordable.
- Cons: Contains trans fats from hydrogenation. Can be messier to work with than liquid oils.

4. avocado oil for seasoning (Best for High-Heat Cooking)
Premium oil with exceptional heat tolerance, though better suited for cooking than seasoning.
- Smoke Point: 520°F (refined)
- Fat Composition: 13% polyunsaturated, 71% monounsaturated, 16% saturated
- Pros: Highest smoke point available. Very stable at high temperatures. Neutral flavor. Health-conscious choice.
- Cons: Most expensive option (3-4x cost of canola). Lower polyunsaturated content means less robust polymerization.
- Best For: High-heat cooking on already seasoned surfaces. Luxury choice for those prioritizing health benefits.

- Clean after every use – I scrape while it’s still warm, then wipe with oil. Takes 5 minutes and prevents 90% of problems.
- Season regularly – Even with non-stick surfaces, a thin oil coating after each use extends the life significantly.
- Cover when not in use – I learned this the hard way after my first griddle rusted. A $30 cover saves hundreds.
- Check connections monthly – I do a soapy water test on gas connections every month. It’s caught small leaks twice.
