Stovetop Rosemary infused Oil Recipe

For those seeking a quicker method to achieve the aromatic bliss of rosemary infused olive oil, the stovetop method offers an expedited path.
This method is perfect for when you’re short on time but still crave the depth of flavor that infused oils add to dishes.
Ingredients:
- Fresh rosemary sprigs (4-6 large ones, or more based on preference)
- Olive oil (approximately 1-2 cups, depending on the size of your pan and desired quantity)
Equipment:
- A small to medium saucepan
- A thermometer (optional, for precise temperature control)
- A clean, dry glass bottle or jar with a tight-fitting lid
- A fine mesh sieve or cheesecloth
- A funnel (optional, for easier pouring)
Instructions:

1. Prepare the Rosemary:
- Clean the rosemary sprigs and ensure they are completely dry to avoid splattering when added to the hot oil.
- Lightly bruise the leaves to help release their essential oils.

2. Heat the Oil:
- Pour the olive oil into the saucepan and warm it over low heat. You want the oil to reach a temperature of about 140°F (60°C) – warm but not too hot to touch.
- If you’re using a thermometer, this helps monitor the temperature to ensure the oil doesn’t overheat, preserving the olive oil’s flavor and health benefits.

3. Infuse the Oil:
- Once the oil is warm, add the prepared rosemary sprigs. Allow the oil to infuse on the lowest heat setting for about 5-10 minutes. Keep an eye on the temperature to ensure it stays in the ideal range.
- The key is to infuse the oil without frying the rosemary, so adjust the heat as necessary.

4. Cool and Strain:
- After infusion, remove the saucepan from the heat and let the oil cool to room temperature.
- Strain the oil through a fine mesh sieve or cheesecloth into a clean, dry bottle or jar to remove the rosemary sprigs and any small particles. Using a funnel can help prevent spills during this step.
5. Store:
- Seal the container tightly with a lid. Store your rosemary infused olive oil in a cool, dark place or the refrigerator. Use within a month for the best flavor and freshness.
Quick Tip:
For a more intense flavor, you can add additional fresh rosemary sprigs to the strained oil after it cools. Just ensure these sprigs are completely dry and clean to avoid spoilage.
This stovetop method is a fantastic way to quickly infuse olive oil with the rich, aromatic character of rosemary, adding a gourmet touch to your cooking with minimal effort.

Zero Waste Tip:
Harvesting rosemary or repurposing stems from other recipes not only makes your infusion personally meaningful but also supports eco-friendly practices. Storing the oil in a reused glass bottle adds rustic charm and promotes sustainability.
Creating rosemary-infused olive oil is straightforward and fulfilling. I started with fresh sprigs from my garden, ensuring they were clean and dry to avoid moisture in the oil. Bruising the leaves to release their oils connected me deeply to the herb’s essence.

I then placed the sprigs in a clean, dry glass bottle, repurposed from a previous culinary project, and poured in olive oil until the rosemary was fully submerged. The bottle was stored in a cool, dark place to infuse, gradually turning the olive oil into a fragrant, rosemary-scented delight.
Infusion requires patience. I let the mixture sit for two weeks, shaking it gently every few days to blend the flavors. This anticipation turned each day into a mini adventure, as I envisioned the myriad ways I could utilize the infused oil.
After two weeks, the oil transformed into a golden liquid, imbued with the potent aroma and essence of rosemary. Its first use was a revelation, enhancing everything from salads to roasted vegetables and morning eggs.

Slow Cooker Rosemary infused Oil
Using a slow cooker to make rosemary infused olive oil is an excellent, hassle-free method that gently coaxes out the flavors of the herb, ensuring a deeply aromatic and flavorful oil.
This method is perfect for those who prefer a “set it and forget it” approach, allowing the slow and low heat to do all the work.
Ingredients:
- Fresh rosemary sprigs (6-8 large ones, or adjust based on preference and slow cooker size)
- Olive oil (enough to fill your slow cooker about halfway, usually 2-4 cups)
Equipment:
- A slow cooker
- A clean, dry glass bottle or jar with a tight-fitting lid
- A fine mesh sieve or cheesecloth
- A funnel (optional, for easier pouring)
Instructions:

1. Prepare the Rosemary:
Thoroughly wash and completely dry the rosemary sprigs to remove any dirt or impurities. It’s crucial that the sprigs are dry to prevent water from getting into the oil.
Lightly bruise the rosemary to release its essential oils, enhancing the infusion process.

2. Combine Ingredients in Slow Cooker:
Place the prepared rosemary sprigs in the slow cooker.
Pour olive oil over the sprigs, ensuring they are fully submerged. The amount of oil used will depend on the size of your slow cooker, but filling it halfway usually works well.
3. Cook on Low Heat:
Cover the slow cooker with its lid. Set it to the low setting and let the oil infuse for about 4-6 hours. The low and slow heat ensures that the oil maintains its quality while extracting the flavors and properties of the rosemary.

4. Monitor the Process:
Check occasionally to ensure the oil is not overheating. You want the oil to be warm and not simmering or boiling to preserve the delicate flavors.
Cool and Strain:
After the infusion time is up, turn off the slow cooker and allow the oil to cool to room temperature.
Once cooled, strain the oil through a fine mesh sieve or cheesecloth into a clean, dry glass bottle or jar. A funnel can be helpful in avoiding spills during this step.
Store Properly:
Seal the container with a tight-fitting lid. Store your freshly made rosemary infused olive oil in a cool, dark place. For best freshness and flavor, use within 1-2 months.

Tips for Success:
- Ensure your rosemary is completely dry before adding it to the oil to prevent any moisture from causing spoilage.
- If you desire a stronger rosemary flavor, you can add more sprigs to the oil or let it infuse for a longer time. Adjust based on your taste preferences.
- Always strain the oil to remove all herb particles, which helps extend its shelf life and maintain clarity and purity.
