Garlic and oregano are two powerful herbs that have been used for centuries in traditional cooking and herbal practices. When infused together in oil, they create a fragrant, flavourful blend that’s perfect for cooking and may provide some health-supporting plant compounds. While garlic and oregano contain compounds that have been studied for their potential health effects, an infusion is not a cure or treatment for disease.
Here’s everything you need to know about garlic and oregano infusion.
What Is Garlic and Oregano Infusion?
A garlic and oregano infusion is typically made by steeping fresh garlic cloves and dried or fresh oregano in a carrier oil such as extra virgin olive oil. The oil absorbs the flavours and some of the aromatic compounds from the herbs, making it ideal for culinary use.
Potential Benefits
1. Rich in Antioxidants
Both garlic and oregano contain antioxidants that help protect cells from damage caused by free radicals.
2. Supports Heart Health
Garlic has been studied for its potential role in supporting healthy cholesterol levels and blood pressure as part of an overall healthy lifestyle.
3. Natural Antimicrobial Compounds
Garlic contains allicin, while oregano contains compounds such as carvacrol and thymol, which have shown antimicrobial activity in laboratory studies. However, this does not mean the infused oil can prevent or treat infections in people.
4. Adds Healthy Flavour
Infused oil can enhance vegetables, grilled meats, pasta, salads, soups, and homemade bread without relying heavily on salt.
Ingredients
- 1 cup (240 ml) extra virgin olive oil
- 4–6 garlic cloves, peeled
- 2 tablespoons dried oregano (or a small handful of fresh oregano)
- Clean, sterilised glass jar or bottle
How to Make Garlic and Oregano Infusion
- Gently warm the olive oil over low heat. Do not let it boil.
- Add the garlic cloves and oregano.
- Simmer very gently for 5–10 minutes, allowing the flavours to infuse.
- Remove from the heat and let the oil cool completely.
- Strain if desired, then transfer the oil to a clean, sterilised bottle.
Important Food Safety Tip
Garlic-in-oil preparations can support the growth of Clostridium botulinum if stored improperly. For homemade garlic-infused oil:
- Refrigerate immediately.
- Use within 3–4 days unless it has been properly acidified using tested food-preservation methods.
- Never store homemade garlic-infused oil at room temperature.
Delicious Ways to Use It
- Drizzle over roasted vegetables.
- Brush onto grilled chicken or fish.
- Toss with pasta.
- Dip fresh bread into it.
- Use in salad dressings.
- Brush over homemade pizza before baking.
Who Should Be Careful?
Garlic may interact with blood-thinning medications and could increase bleeding risk. If you’re taking anticoagulants, have a bleeding disorder, or are preparing for surgery, speak with your healthcare provider before consuming large amounts of garlic or garlic supplements.
Final Thoughts
Garlic and oregano infusion is a simple way to add rich Mediterranean flavour to everyday meals while enjoying herbs that are naturally rich in beneficial plant compounds. Just remember that it is best appreciated as a delicious culinary ingredient—not as a substitute for medical treatment—and homemade garlic-infused oil should always be stored safely in the refrigerator to reduce the risk of foodborne illness.
