Ingredients You’ll Need
The beauty of this Lemongrass Chili Oil Recipe lies in its straightforward, everyday ingredients. Each element plays a crucial role in creating a harmonious balance of flavor, color, and texture that makes this oil truly irresistible.
- 1 cup neutral oil: Choose vegetable or canola oil for a clean base that lets the aromatics shine.
- 2 stalks lemongrass: Finely minced to release bright, citrusy notes that brighten the oil.
- 4 cloves garlic: Thinly sliced for a mellow yet pungent flavor punch.
- 2 shallots: Thinly sliced; they add a subtle sweetness and delicate texture.
- 2 tablespoons red pepper flakes: The heat source that brings warmth and color.
- 1 teaspoon chili powder (optional): Use this for an extra layer of smoky heat.

- 1 teaspoon sugar: Balances the spice with a touch of sweetness.
How to Make Lemongrass Chili Oil Recipe
Step 1: Heat the Oil with Aromatics
Start by gently heating your neutral oil over medium heat in a small saucepan. Once warm, add the finely minced lemongrass, thinly sliced garlic, and shallots. Stir these fragrant aromatics frequently for about 5 to 7 minutes until they turn a gorgeous golden brown. This slow cooking process is crucial because it draws out the depth of flavor without burning the ingredients.
Step 2: Cool the Oil Slightly
After your aromatics have beautifully browned and filled your kitchen with amazing scents, remove the saucepan from the heat. Allow the oil to cool for 2 to 3 minutes. This slight cooling step prevents the spices from scorching in the next phase, ensuring your chili oil is perfectly balanced.
Step 3: Add Spices and Seasonings
Once the oil is just warm, stir in the red pepper flakes, optional chili powder for extra heat, salt, and sugar. These seasonings infuse the oil with layers of spice, savoriness, and a hint of sweetness that round out the flavor profile beautifully.
Step 4: Let the Flavors Infuse
To get the most out of your Lemongrass Chili Oil Recipe, let the mixture cool completely. This resting period allows all the aromatics and spices to deepen and meld together, resulting in a condiment that bursts with complexity and warmth in every drop.
Step 5: Store and Enjoy
Once cooled, transfer your chili oil to a clean jar and seal it tightly. Store it in the refrigerator where it will keep deliciously fresh for up to two weeks. Use it generously on your favorite dishes for an instant flavor boost!

FAQs
Can I use other oils besides vegetable or canola?
Yes, you can experiment with oils like grapeseed or sunflower for a similar neutral flavor. Avoid olive oil as it has a strong taste that can overpower the lemongrass and chili.

Should I strain out the solids after cooking?
That’s totally up to you! Leaving the garlic, shallots, and lemongrass in adds wonderful texture and bursts of flavor. If you prefer a smooth oil, strain them out before storing.
