Marinating Steak: Avocado Oil vs Canola Oil

Marinating Steak: Avocado Oil vs Canola Oil for Pan Searing

Chimichurri is often thought of as a finishing sauce — spooned over steak after it comes off the grill. But sometimes it serves another purpose: it becomes a marinade. When that happens, the oil inside the chimichurri is no longer just a structural carrier for herbs. It is exposed to pan heat. That changes the conversation.

If you’ve read our prior comparisons — including Canola Oil vs Olive Oil in Chimichurri, Avocado Oil vs Canola Oil: Which One Is Right for You?, and our broader health-focused discussion of Avocado Oil vs Canola Oil: Which Is Healthier? — you already know that oil choice can influence structure, nutrition, and sometimes flavor. This article narrows the focus further: if chimichurri is used to marinate steak and then pan-seared, which oil holds up better to heat?

 

What Happens to Oil During Pan Searing?

When oil is exposed to high heat, especially above 350–400°F as is common during pan searing, oxidative reactions begin to occur. Lipid oxidation produces primary oxidation products (lipid hydroperoxides) and secondary compounds such as aldehydes, which may influence flavor and nutritional integrity. The rate of oxidation depends largely on the number of double bonds in the fatty acids present.

As described in the lipid oxidation review by Choe & Min (2007), polyunsaturated fats oxidize more readily than monounsaturated fats because they contain multiple double bonds that are more chemically reactive under heat and oxygen exposure. This biochemical principle underlies much of the discussion around the best oil for pan searing meat.

 

Fatty Acid Composition and Thermal Stability

Avocado oil is composed of approximately 65–75% monounsaturated fat, primarily oleic acid, according to compositional analyses reviewed by Dreher & Davenport (2013). Monounsaturated fats contain a single double bond, making them structurally more resistant to oxidative degradation than polyunsaturated fats under heat exposure.

Canola oil contains roughly 60% monounsaturated fat but also provides a higher proportion of polyunsaturated fats, including linoleic acid and alpha-linolenic acid (ALA), as detailed by Lin et al. (2013). While these polyunsaturated fats are associated with favorable cardiovascular markers when replacing saturated fats, they are somewhat more prone to oxidation during high-temperature cooking.

This does not mean canola oil is unsafe for pan searing steak. It means that, from a structural standpoint, oils higher in monounsaturated fat — such as avocado oil — generally demonstrate slightly greater oxidative stability during brief high-heat exposure.

Smoke Point vs. Oxidative Resistance

Smoke point is often cited in discussions about the best oil for marinating steak or pan searing meat. However, smoke point refers to the temperature at which visible smoke forms — not the temperature at which oxidation begins. As emphasized by Choe & Min (2007), oxidative changes can occur prior to visible smoke production.

Refined avocado oil typically has a higher smoke point than refined canola oil. More importantly, its fatty acid structure — with a higher proportion of monounsaturated fats — offers modestly greater resistance to lipid peroxidation under high heat. In the context of a marinade that directly contacts a hot pan, that structural difference becomes relevant, even if the practical impact remains moderate under short cooking durations.

Health Context Under Heat

From a cardiovascular perspective, both oils are associated with improved lipid markers when replacing saturated fats. The Cochrane review led by Hooper et al. (2020) concluded that replacing saturated fat with unsaturated fat reduces cardiovascular events. Similarly, monounsaturated fats have been linked with favorable cardiovascular profiles in reviews such as Schwingshackl & Hoffmann (2014).

Therefore, even when discussing the best oil for pan searing meat, the larger health picture remains grounded in overall dietary patterns rather than minor differences in heat stability during a few minutes of searing.

 

So Which Is the Best Oil for Marinating Steak?

If chimichurri is used solely as a finishing sauce, heat stability is irrelevant. But if it is used as a marinade and then pan-seared, avocado oil provides a modest structural advantage due to its higher monounsaturated fat content and slightly greater oxidative resistance.

Canola oil remains appropriate for moderate pan searing under typical home cooking conditions. The difference between the two oils is measurable in lipid chemistry but modest in practical culinary effect.

  • Avocado oil: slightly greater oxidative resistance during high heat.
  • Canola oil: nutritionally favorable and suitable for short-duration searing.
  • Both: appropriate for marinating steak under normal cooking conditions.

If the goal is choosing the most heat-stable oil for pan searing meat after marination, avocado oil holds a small compositional edge. If the goal is overall dietary balance, both oils remain reasonable choices.

 

Compare Our Chimichurri for Steak

Both versions maintain the same herb-forward profile. The difference lies in the oil composition and how it behaves under heat.
