Cooking with Essential Oils — What You Need to Know

Ever tried cooking with essential oils? It’s an exciting way to experiment with dishes by giving them vibrant aromas and concentrated flavors with just a drop or two! Here, we'll cover the basics of cooking with essential oils, including which ones are safe to consume and practical tips for adding rich, bold flavors to your meals.

What are Essential Oils?

Essential oils are highly concentrated compounds or extracts that are derived from various herbs, flowers, or fruits and capture the very “essence” or flavor of the source plant. 

There are several methods of obtaining these oils, such as through cold pressing (squeezing the plant without heat) or steam distillation (where the plants are heated until their oils evaporate, which are then condensed and collected). 

Common examples include chamomile, eucalyptus, lavender, ginger, and citrus oils such as lemon, lime, and orange essential oils. While essential oils are commonly used in aromatherapy and personal care, there's growing experimentation around incorporating them into cooking as well.

Is Cooking with Essential Oils Safe?

The short answer is: it depends. Those labeled “food-grade” are safe, but only if they are used correctly.

The Food and Drug Administration (FDA) has a category called GRAS, or Generally Recognized as Safe, which includes some essential oils if used in food in small amounts. This includes peppermint, lemon, orange, lavender, cinnamon, ginger, and basil oil.

Note, however, that these oils are never meant to be ingested on their own and should always be added in minute amounts to something else. 

Moreover, there are essential oils that shouldn’t be ingested at all. This includes eucalyptus, tea tree, and pennyroyal oil. Consuming them may cause adverse effects such as persistent vomiting, chest pain, or even loss of consciousness. 

Which Essential Oils Can Be Used for Cooking?

Below are some essential oils that can be used in the kitchen as flavorful ingredients. Some of these oils can also serve as a natural spice alternative, offering bold flavor with just a drop.

• Basil: Adds a bright, herbal flavor to soups, stews, or tomato-based dishes.
• Lime: Works great in salad dressings and marinades. 
• Ginger Oil: Brings warmth and depth to stir-fries, vegetables, and chicken dishes.
• Rosemary: Combine with olive oil or butter before adding to roasted potatoes or meats for an herbal touch.  
• Thyme: Imparts a savory and earthy note to soups and stews.
• Lavender: Can be used sparingly in desserts.
• Orange: Brightens up sweets and glazes with its citrus zest flavor.
• Black Pepper: Adds a punch to rubs and savory recipes. 
• Marjoram: Gives a mildly herbaceous flavor to delicate sauces and roasted veggies.
• Peppermint: Use sparingly to give chocolates and holiday treats a cool, refreshing note. 
• Lemon: Adds a crisp, fresh brightness to butter sauces, marinades, and salads. 
• Cinnamon: Perfect for adding warmth to autumn desserts, baked goods, and oatmeal recipes. 

Remember, essential oils are concentrated essences, so using less is more to avoid overpowering your dishes. 

Tips and Tricks for Cooking with Essential Oils

1. Dilute Properly - Blend the essential oils with carriers such as butter, olive oil, or coconut oil before adding them to meals. This will help distribute the flavors evenly throughout your dish.
2. Add at the Right Time - Many oils, like the citrus varieties, lose their flavor when exposed to high heat for too long. For best results, add them toward the end of the cooking process, or just before serving. 
3. Make Sure to Stir Thoroughly - This helps avoid getting accidental bursts of concentrated flavor in just one bite!
4. Pair with Fresh Herbs - To help keep your dishes tasting more natural and well-rounded, try pairing the essential oil with fresh herbs. For example, combine fresh rosemary with rosemary oil in a roast, or pair lime zest wth lime oil in a vinaigrette. 
5. Start Really, Really Small - This can’t be stressed enough! Many chefs recommend using a “toothpick swirl,” where you dip a toothpick into the essential oil bottle and then swirl it into your food. This allows you to take control of the dish’s taste instead of letting the oil overpower your food. 
6. Store Them Properly - Keep your essential oils away from heat and light, as exposure might change or degrade their flavor profile over time. Also, label food-grade oils properly and store them separately from other oils to avoid any untoward incidents.
