Cooking on a Blackstone griddle is generally a healthy way to prepare food, and in some respects healthier than traditional charcoal grilling. Blackstone griddles are made from cold-rolled steel with no chemical non-stick coatings, and their flat cooking surface avoids the direct flame contact that produces the most concerning cancer-linked compounds in grilled meat. That said, a few factors, like your oil choice and how dark you cook starchy foods, affect how healthy the final meal actually is.
No Chemical Coatings to Worry About
Blackstone griddles use bare cold-rolled steel, not the kind of chemical non-stick surfaces found on many pans and cookware. There’s no PFOA, PFAS, or Teflon-style coating involved. Instead, you build a natural non-stick layer through “seasoning,” which means heating a thin coat of oil until it chemically bonds to the steel surface. This polymerized oil layer is stable enough that even soap won’t wash it off, and food scientists at Virginia Tech have confirmed there are no food safety concerns with cooking on this type of seasoned surface. It simply acts as a protective barrier that prevents rust and keeps food from sticking.
Less Exposure to Cancer-Linked Compounds Than Charcoal
One of the biggest health advantages of a Blackstone over a charcoal grill is reduced formation of polycyclic aromatic hydrocarbons, or PAHs. These compounds form when fat drips onto open flames or hot coals and the resulting smoke deposits back onto the meat. On a flat griddle, there’s no open flame and no drip-flare cycle. Research published in Scientific Reports found that charcoal-grilled meat contained about 34.9 μg/kg of total PAHs compared to 30.16 μg/kg for gas-cooked meat. The difference was even more dramatic for benzo[a]pyrene, one of the most harmful PAHs: 24.2 μg/kg in charcoal-grilled samples versus just 5.7 μg/kg in gas-cooked ones. Airborne PAH levels tell an even starker story. Cooking over charcoal produced 23.1 µg/m³ of PAHs in the surrounding air, while gas cooking produced just 0.008 µg/m³.
A Blackstone runs on propane or natural gas with a solid steel barrier between the flame and your food, which puts it firmly in the lower-risk category. Fat stays on the flat surface rather than dripping into fire, eliminating the main mechanism that generates these compounds.
Oil Choice Matters More Than You Think
Griddle cooking requires oil, both for seasoning and for everyday cooking. When oil is heated past its smoke point, it breaks down and produces harmful chemicals including peroxides and aldehydes that can damage cells. Since a Blackstone can easily reach temperatures above 500°F in spots, choosing the right oil is critical.
The best options for high-heat griddle cooking are oils with smoke points at or above 392°F:
- Avocado oil: 482°F smoke point, one of the most versatile choices
- Rice bran oil: 450°F smoke point
- Peanut oil: 446°F smoke point
- Refined olive oil: 390–470°F smoke point (regular extra virgin olive oil has a lower threshold and isn’t ideal for searing)
- Safflower, soybean, or sunflower oil: 450°F smoke point
Avoid flaxseed oil for cooking (its smoke point is too low, though some people use it for seasoning at controlled temperatures). Butter, coconut oil, lard, and ghee may handle high heat, but they’re high in saturated fat, which raises cholesterol and heart disease risk with regular use. If you’re cooking on a Blackstone several times a week, your oil choice adds up.
Watch the Color on Starchy Foods
Blackstone griddles are popular for hash browns, potato slices, and pancakes, but starchy foods cooked at high temperatures produce acrylamide, a chemical the FDA flags as a potential health concern. Frying produces the highest levels of acrylamide among common cooking methods, and a griddle functions similarly to a frying surface for thin, high-heat items like potato slices.
The practical fix is simple: cook to golden yellow, not brown. The darker the color, the more acrylamide has formed. Soaking raw potato slices in water for 15 to 30 minutes before cooking also reduces acrylamide formation significantly. One less obvious tip from the FDA: don’t store potatoes in the refrigerator, as the cold converts some starches to sugars that produce more acrylamide when heated. Keep them in a cool, dark pantry instead.
Portion Control and Added Fat
The flat surface of a Blackstone gives you precise control over how much oil you use. Unlike deep frying, where food is submerged, griddle cooking lets you apply a thin layer and cook with relatively little added fat. You can also cook vegetables, shrimp, fish, and lean proteins with minimal oil, making it easy to keep meals lighter. The large cooking surface is actually an advantage here because you can spread food out in a single layer, which promotes browning without needing extra fat for heat transfer.
That said, a Blackstone also makes it very easy to cook smash burgers, cheesesteaks, and bacon in pools of rendered fat. The tool itself is neutral. The health outcome depends mostly on what you put on it and how much oil or butter you add.
How It Compares to Other Cooking Methods
Steaming and boiling are the gentlest cooking methods in terms of harmful compound formation, producing virtually no PAHs or acrylamide. A Blackstone won’t match that. But compared to charcoal grilling, it produces fewer carcinogenic compounds. Compared to deep frying, it uses far less oil. Compared to non-stick pans, it avoids synthetic coatings entirely.
The griddle sits in a practical middle ground: it delivers high-heat flavor with lower chemical risk than open-flame grilling, and it gives you direct control over fat content. Choosing a high smoke point oil, keeping starchy foods golden rather than dark, and favoring vegetables and lean proteins alongside the occasional smash burger keeps Blackstone cooking well within healthy territory.
