When you first flip a steak on a Blackstone griddle, the surface should feel silky, not sticky. That silky feel comes from a proper seasoning process, and the secret lies in choosing the right oil. In this guide you’ll discover the best oil to season Blackstone, how to apply it, and why your grill’s performance depends on it.
Seasoning a griddle is more than a ritual—it protects the metal, reduces rust, and delivers that coveted non‑stick, caramelized flavor to every bite. If you’re unsure which oil to use, you’re not alone. Many grillers flip through forums and product catalogs, hoping to find the perfect match. Below, we break down the top oil options, their pros and cons, and the exact steps to get the best results.
Understanding the Science of Seasoning a Blackstone
What Happens When Oil Seals the Metal?
When you heat oil on a metal surface, the oil molecules bond to the metal and polymerize into a thin, hard film. This film protects the griddle from moisture and oxidation.
Why Temperature Matters
Seasoning requires a high temperature—usually between 250°F and 300°F—to trigger polymerization. At lower temperatures, the oil won’t bond properly, leaving the surface prone to sticking.
The Role of Smoke Point
Oils with higher smoke points stay stable under heat. If the oil smokes quickly, it can create off‑flavors and leave a sticky residue.
Top 7 Oils for Seasoning Your Blackstone Griddle
1. Avocado Oil – The Gold Standard
Avocado oil boasts a smoke point of about 520°F, making it ideal for high‑heat seasoning. Its neutral flavor ensures no taste transfer to your food.
2. Grapeseed Oil – Budget‑Friendly and Reliable
With a smoke point around 420°F, grapeseed oil offers great polymerization while being affordable. It’s a popular choice for home grillers.
3. Vegetable Oil – The Stockpile Option
Most kitchen cabinets already contain vegetable oil. Though its smoke point is lower (≈400°F), it still works well if you maintain an even, thin coat.
4. Canola Oil – Lean and Light
Canola oil’s 400°F smoke point and low saturated fat content make it a healthy alternative for seasoning.
5. Flaxseed Oil – Ultra‑High Smoke (But Requires Care)
Flaxseed oil polymerizes well at lower temperatures, but it’s highly reactive. Use a thin layer and avoid high heat for extended periods.
6. Peanut Oil – Aromatic and Durable
Peanut oil’s 450°F smoke point adds a subtle nutty scent. It’s a favorite among professional chefs for its durability.
7. Extra‑Virgin Olive Oil – Best for Small‑Scale Grilling
Olive oil has a lower smoke point (~375°F), so it’s suited for smaller griddles or when you want a subtle Mediterranean flavor.

Step‑by‑Step Guide to Seasoning with Your Chosen Oil
Preparation: Clean and Dry
Before seasoning, scrub the griddle with a mild detergent and warm water. Rinse thoroughly and dry with a clean cloth.
Heating the Griddle
Preheat the Blackstone to 250°F–300°F. Use a digital thermometer to check the exact temperature.
Applying the Oil
Pour a small amount of oil onto a paper towel. Spread a thin, even layer across the entire surface, including corners and edges.
Allowing the Oil to Polymerize
Keep the griddle at the target temperature for 20–30 minutes. Do not add more oil during this time.
Cooling and Wiping
Turn off the heat and let the griddle cool. Once cool, wipe off any excess oil with a paper towel.
Repeat for a Durable Coating
For first‑time users, repeat the seasoning process 2–3 times. New grill owners should season at least once per month to maintain a strong layer.

Pro Tips for Maintaining Your Blackstone’s Seasoned Surface
- Use a paper towel for a thin, even oil layer.
- Preheat to 250°F–300°F each time you season.
- Store the griddle covered to prevent dust from settling on the oil.
- Clean with a damp cloth after each use; avoid harsh detergents.
- Season monthly if you grill frequently; less often if used sparingly.
- Never use metal utensils on a freshly seasoned surface; use silicone or wooden tools instead.
- Check for rust spots and re‑season immediately if found.
- Keep the griddle dry before storage to avoid moisture buildup.
Frequently Asked Questions about best oil to season blackstone
What is the best oil to season a Blackstone griddle for maximum durability?
Avocado oil is the top choice because of its high smoke point (≈520°F) and excellent polymerization, providing a tough, long‑lasting coating.
Can I use the same oil I use for cooking on the Blackstone?
Yes, but choose oils with higher smoke points if you plan to season at high heat. Cooking oils like olive or butter may not polymerize well.
How often should I re‑season my Blackstone after the first season?
Season the griddle once a month if you grill frequently. For occasional use, every 3–6 months is sufficient.
Will seasoning with avocado oil change the taste of my food?
No. Avocado oil has a neutral flavor, so it won’t alter the taste of the food you cook.
Is it safe to use peanut oil for seasoning if I have a nut allergy?
Peanut oil can leave residues. If you or your guests have allergies, opt for a non‑nut oil like grapeseed or canola.
How do I know if my seasoning layer is too thick?
A thick layer is visible as a slick sheen and can cause sticking. Use a paper towel to spread just a thin film.
Can I season my Blackstone with olive oil?
Extra‑virgin olive oil is not ideal due to its lower smoke point (≈375°F). It can work on small griddles, but it’s less durable.
What should I do if my Blackstone has developed rust spots?
Remove rust with a steel wool pad, then re‑season with your chosen oil. Avoid sanding the whole surface.
Is it okay to season with a combination of oils?
Yes, you can mix oils, but keep the ratio balanced. A common mix is two parts avocado to one part grapeseed for a stable, high‑smoke layer.
Do I need to season my Blackstone every time I clean it?
No. Season only after cleaning if the surface shows signs of wear or if you notice sticking.
Conclusion
Choosing the best oil to season Blackstone is a simple decision when you know the key factors: smoke point, polymerization, and flavor neutrality. Avocado oil tops the list for durability, while grapeseed and canola oil provide great budget alternatives. Follow the step‑by‑step seasoning guide and the expert tips above to keep your griddle rust‑free and ready for every cookout.
Now that you have the essential knowledge, grab your favorite oil, fire up the Blackstone, and enjoy a perfectly seasoned cooking surface that will last for years. Happy grilling!
