what is the best oil to cook with

The best everyday cooking oil for most people is extra-virgin olive oil , with avocado oil a close second when you need very high heat.

Key takeaway

• For general cooking and health, extra-virgin olive oil is the top choice: rich in monounsaturated fats and antioxidants, and linked to better heart health and lower risk of chronic disease.

• For very high-heat cooking (searing, high-temp stir-fries), avocado oil or refined olive/rapeseed (canola) oil are excellent because of their higher smoke points.

What “best oil” really depends on

You’re really choosing based on three things:

• Health profile (type of fat, antioxidants, additives)

• Cooking method and heat (smoke point)

• Flavor and what you like eating every day

There is no single perfect oil for every situation, but some are consistently better for both health and cooking versatility.

Top oils to keep in your kitchen

Extra-virgin olive oil (EVOO)

• High in monounsaturated fat (especially oleic acid), plus natural antioxidants and anti‑inflammatory compounds that support heart health and may lower risk of type 2 diabetes.

• Works well for low–medium heat cooking (sautéing, roasting) and for salads, dips, and finishing dishes, and modern evidence shows it is still safe and stable for normal cooking.

Avocado oil

• Similar healthy fat profile to olive oil, rich in monounsaturated fats and linked to cardiovascular benefits.

• Has a higher smoke point than most olive oils, so it is excellent for high-heat searing, stir‑fry, and roasting while still being relatively stable.

Rapeseed / canola oil (quality, cold-pressed if possible)

• Lower in saturated fat, with a good balance of monounsaturated fat and omega‑3s and a favorable omega‑6 to omega‑3 ratio.

• Neutral flavor, versatile for general cooking and baking; refined versions handle medium–high heat, making them practical for everyday use.

Specialty “finishing” oils (flaxseed, walnut, toasted sesame)

• Often rich in omega‑3s or unique antioxidants, so they’re good for drizzling on salads or cooked dishes, not for high‑heat frying due to low smoke points.

• Best used in small amounts because they are delicate, can oxidize faster, and are usually more expensive.

Oils better to limit

• Highly refined, high‑omega‑6 seed oils (like generic “vegetable oil,” some sunflower and corn oils) are more prone to oxidation and can skew omega‑6 to omega‑3 balance when used heavily.

• Repeatedly reusing oil for deep‑frying at high temperatures increases breakdown products that are not great for health, regardless of which oil you start with.

Quick practical guide

• Daily cooking, roasting, most frying: extra-virgin olive oil first, avocado oil or rapeseed/canola as strong alternatives.

• Very high heat searing/stir‑fry: avocado oil or a refined olive/rapeseed oil.

• Salads and finishing: extra-virgin olive , walnut , flaxseed , or toasted sesame in small amounts.
