Infused olive oil is simply olive oil that’s been flavored by adding herbs, spices, or other ingredients. Think of it like turning regular olive oil into a flavor powerhouse! You can use ingredients like garlic, rosemary, chili peppers, lemon zest, and more to create a customized oil that suits your taste.

Heart-healthy fats: Olive oil is rich in monounsaturated fats, which can help reduce bad cholesterol levels and support cardiovascular health.
Anti-inflammatory properties: Infusing olive oil with garlic, rosemary, or chili peppers adds compounds like allicin, carnosol, and capsaicin, which have natural anti-inflammatory properties.
Antioxidant boost: Ingredients like basil and thyme are packed with antioxidants, helping fight free radicals and supporting immune health.
Cost-effective: You only need a few ingredients, many of which you probably already have at home.

Step-by-step guide: How to make infused olive oil

Ready to try making your own infused olive oil? Here’s a simple guide to get started.

What you’ll need:

Extra virgin olive oil (choose a high-quality oil for the best flavor)
Your choice of fresh or dried herbs, spices, or aromatics
Small saucepan (if using the warm method)
Glass jars or bottles for storing

Infusion methods:

You can infuse olive oil in two primary ways: cold infusion or warm infusion.

1. Cold infusion (best for dried herbs and spices):

This method is simple and doesn’t require heating the oil, making it great for preserving the delicate flavor of herbs.

Choose your dried ingredients: Select dried herbs, spices, or citrus peels. Using dried ingredients reduces the risk of bacterial contamination.
Add to a jar: Place your ingredients into a clean glass jar or bottle.
Pour olive oil: Fill the jar with olive oil, making sure your ingredients are fully submerged.
Let it sit: Store the jar in a cool, dark place for 1-2 weeks. Shake it every few days to mix the flavors.
Strain and store: After the infusion period, strain the oil using a fine-mesh sieve or cheesecloth. Pour into a clean bottle and it’s ready to use.

2. Warm infusion (for stronger, faster flavor):

This method involves gently heating the oil, which helps release the flavors from the ingredients more quickly.

Add ingredients to the oil: Combine your chosen herbs or spices (like garlic or rosemary) with olive oil in a saucepan.
Heat gently: Warm the oil over low heat for about 10-15 minutes, making sure it doesn’t reach a simmer (keeping the temperature below 180°F is key).
Cool and strain: Once you smell the aroma of the ingredients, remove the oil from heat, let it cool, and strain out the solids.
Store and use: Pour into a clean bottle and enjoy!

Important safety tip: If you use fresh ingredients (like fresh garlic or herbs), it’s crucial to store the oil in the refrigerator and consume it within a week to prevent bacterial growth, including botulism. Dried herbs have a much lower risk and can be stored longer at room temperature.

How to store infused olive oil

Once you’ve made your infused olive oil, storing it properly is key to maintaining its flavor and safety.

Room temperature or fridge?: If you’ve used dried herbs and spices, you can store the oil in a cool, dark place, like your pantry. If you’ve used fresh ingredients, refrigerate the oil to extend its shelf life.
Shelf life: Dried herb-infused oils can last up to a month when stored in a cool, dark place. Fresh ingredient infusions should be consumed within a week or stored in the fridge for up to two weeks.
Watch for spoilage: If the oil smells off or shows signs of cloudiness or mold, discard it immediately.

Best uses for different infused olive oils

Here’s how to match the right infused olive oil with different dishes:

Garlic-infused oil: Ideal for sautéing vegetables, roasting meats, and drizzling over pizza.
Rosemary-infused oil: Pairs well with roasted potatoes, grilled lamb, and focaccia bread.
Chili-infused oil: Use as a finishing touch on pasta, pizza, or stir-fries for a spicy kick.
Lemon-infused oil: Perfect for salads, seafood, or drizzling over roasted asparagus.
Basil-infused oil: Works great as a base for pesto, drizzled over tomatoes, or added to pasta salads.

Delicious recipes using infused olive oil

Here are a few easy ways to incorporate your infused olive oil into everyday dishes:

1. Garlic and rosemary-infused olive oil for roasted potatoes

Tip: Use this oil to coat your potatoes before baking to ensure crispy edges and rich, savory flavor.

Toss cubed potatoes with 2-3 tablespoons of garlic and rosemary-infused olive oil, salt, and pepper.
Roast at 400°F (200°C) for 35-40 minutes until golden and crispy.

2. Chili-infused olive oil for pasta

Tip: A little chili oil goes a long way, so start with just a tablespoon for a mild heat, or add more for a spicier kick.

Drizzle 1-2 tablespoons of chili-infused oil over freshly cooked pasta.
Toss with sautéed garlic, a sprinkle of parmesan cheese, and fresh parsley for a quick, spicy pasta dish.

3. Lemon-infused olive oil for salads

Tip: Pair lemon-infused oil with balsamic vinegar or red wine vinegar for a light and zesty dressing.

Combine 2 tablespoons of lemon-infused olive oil with 1 tablespoon of balsamic vinegar.
Drizzle over mixed greens, cherry tomatoes, and cucumber for a refreshing summer salad.
