How to Make Achiote (Annatto) Oil: Step-by-Step Guide

Dec 2, 2025

Achiote oil, also known as annatto oil, is a vibrant, flavor-packed ingredient popular in Caribbean and Latin American cuisines. This all-natural, homemade condiment not only enhances the color of your dishes but also provides a unique depth of flavor. Whether you’re making rice, soups, marinades, or stews, this versatile oil is a must-have for any culinary enthusiast looking to elevate their cooking game.

In this guide, we’ll walk you through how to make achiote oil, explain its benefits, and highlight creative ways to incorporate it into your kitchen routine.

What Is Achiote (Annatto) Oil?

Achiote oil is a fragrant cooking oil infused with annatto seeds, which are derived from the seeds of the achiote tree. These seeds are widely used as a natural food coloring and flavor enhancer. The oil is a staple in many Caribbean countries like Puerto Rico and the Dominican Republic, where it’s used to add a rich orange-red hue and a subtle earthy flavor to dishes.

Unlike artificial additives (like red dye #40), achiote oil is entirely natural and free of harmful chemicals, making it an excellent choice for health-conscious cooks. But there’s a trick to making it: overcooking the annatto seeds can result in a bitter flavor, so careful attention is key.

Ingredients You’ll Need

Creating achiote oil is surprisingly simple, requiring just a few key ingredients:

Core Ingredients:

Annatto Seeds: These small, reddish seeds are the star of the show, delivering both color and flavor.
Neutral Oil: Canola oil works well, but you can mix in olive oil for added depth and richness.

Flavor Enhancers:

Aji Dulce (Kachucha Peppers): These sweet peppers, related to habaneros, add a subtle sweetness without heat.
Garlic: Adds a robust, earthy undertone.
Culantro (or Cilantro): A fragrant herb that deepens the oil’s flavor profile.

Step-by-Step Guide to Making Achiote Oil

Here’s how to create this multi-purpose oil in your own kitchen:

1. Prepare Your Ingredients

Wash and dry fresh ingredients like culantro, garlic, and aji dulce.
Lightly smash garlic cloves to release their flavor.

2. Heat the Oil

In a small pot, pour your neutral oil (e.g., canola) and heat over low-medium heat. For added flavor, mix in a bit of olive oil.

3. Infuse the Oil

Add the crushed garlic cloves and whole aji dulce peppers to the oil. Let them cook gently, releasing their aroma.
Toss in fresh culantro stems - don’t skip the stems, as they’re packed with flavor.

4. Add Annatto Seeds

Stir in the annatto seeds, using about 1 teaspoon per ½ cup of oil.
Allow the seeds to steep in the warm oil for around 10 minutes. Keep the heat low to prevent bitterness - the oil should turn a stunning orange-red without smoking.

5. Cool and Strain

Remove the pot from heat and let the oil cool.
Strain the oil into a clean container, discarding the solids.
Store the oil in a bottle with a secure spout for easy use.

How to Use Achiote Oil in Your Cooking

The beauty of achiote oil lies in its versatility. Here are some creative ways to incorporate it into your recipes:

Base Oil for Cooking: Use it to sauté onions, garlic, or vegetables for soups and stews.
Rice and Beans: Add a splash to give your side dishes a pop of color and flavor.
Marinades: Combine achiote oil with herbs, spices, and citrus juice to create a flavorful marinade for chicken, pork, or fish.
Salad Dressings: Whisk it with vinegar and spices for a colorful and aromatic dressing.
Soups and Stews: Achiote oil is perfect for comforting dishes like chicken soup or beef stew, especially in cooler months.

Expert Tips for Success

Monitor the Heat: Keep the oil at a low temperature to avoid burning the annatto seeds, which can create a bitter taste.
Use Fresh Ingredients: The quality of your garlic, peppers, and culantro will directly impact the flavor of the oil.
Store Properly: Once cooled, store the oil in an airtight container in a cool, dark place. It should last for several weeks.
Experiment and Innovate: Don’t be afraid to customize the recipe by adding spices like cumin or oregano for a unique twist.
