Ingredients List

• 1 cup finely chopped yellow onion (about 1 medium onion)

• Optional: 1–2 cloves garlic, minced (for extra flavor)

4. Add garlic (optional): If you like a bit of garlic punch, toss it in now and cook for another 30 seconds until fragrant. Don’t stress if it’s a little chunky; it will soften further in your dish.

Serving Suggestions

The Holy Trinity is incredibly versatile. Use it as the first step in making gumbo, jambalaya, etouffee, or red beans and rice. It also adds great depth when sautéed with sausage, seafood, or chicken. Think of it as your trusty flavor foundation—once you master it, endless delicious dishes await.

Origin & History

The term “Holy Trinity” in Louisiana cooking draws inspiration from the traditional French mirepoix, which blends onions, carrots, and celery. But Cajun and Creole cooks swapped carrots for bell peppers, adapting the mix to local flavors and ingredients. This trio underpins much of Louisiana’s vibrant culinary heritage, connecting history and culture in every bite.

Fun fact: The Holy Trinity isn’t just cooking jargon—it’s a beloved symbol of Southern hospitality, flavor, and tradition passed down from generations.

Variations & Substitutions

• Heat it up: Add diced jalapeños or cayenne pepper for a spicy kick.
• Low FODMAP: Use green bell peppers and celery but omit onions or substitute with asafoetida powder sparingly.
• Regional twists: Some recipes incorporate tomatoes or add garlic upfront for a more robust flavor profile.
• Oil choices: Swap vegetable oil with bacon fat or duck fat for a smoky depth.

Storage & Make-Ahead Tips

You can prepare the Holy Trinity ahead of time and refrigerate it in an airtight container for up to 3 days. It reheats beautifully—just warm over medium heat before adding it to your recipe. Want to freeze it? No problem. Pack in freezer-safe containers or bags and use within 2 months. Just thaw overnight in the fridge for best results.
