“This sauce was delicious! I was looking for a homemade version similar to the Frontera ready-made sauce that my family likes, and this was the perfect choice. The adobo sauce adds just enough of a kick without being overly spicy. I will definitely be making this again. Thanks for a great recipe!” -Katie

Ingredients You’ll Need

This easy fajita sauce takes just 5 minutes to put together, and it’s loads better than most store-bought brands. Though these days, there are some great all-natural brands out there! Here’s what you’ll need in addition to salt (or jump right to the recipe for quantities):

Fresh lime juice: Fresh-squeezed is worth it here for the best zingy flavor.
Adobo sauce: From 1 can of chipotle peppers in adobo (see more below!).
Olive oil: This helps the sauce cling as a marinade.
Cumin: This is the key to that classic fajita seasoning flavor.
Garlic powder: Distributes evenly, so every bite gets garlicky warmth without having to mince garlic.

That’s it! Whisk together everything in a bowl, and it becomes a seriously delicious Tex Mex marinade. It’s got a kick from the lime and a smoky nuance that’s incredibly irresistible.

The Key Ingredient: Chipotle Peppers in Adobo Sauce

The key ingredient to this fajita sauce is adobo sauce, which adds a smoky nuance and complexity that is impossible to replicate! There’s no great substitute so it’s worth finding the real thing.

Where to find it: Look for a small can labeled chipotle peppers in adobo sauce; they’re easy to find at most grocery stores near the Mexican products. The can includes chipotle chiles (smoked and dried jalapeños that are rehydrated) canned with adobo sauce, a purée of tomato, vinegar, garlic, and spices.
Use the sauce, not the peppers. Use a spoon to remove the adobo sauce from the can, working around the hot peppers.
Control the heat. Use 1 tablespoon for a mild fajita sauce, and 2 tablespoons for a moderately spicy (not even medium).
Save the leftovers. Refrigerate or freeze the remainder, and use it for more adobo sauce recipes like tortilla soup, chipotle ranch dressing, or enchilada sauce.

How to Use Fajita Sauce as a Marinade (Chicken, Steak & Shrimp)

This fajita sauce also works with chicken, steak, or shrimp as a marinade. Here’s what to do:

Use 1 pound of any protein. If using shrimp, use peeled and deveined.
Marinade with the protein for 20 minutes. Whisk together the ingredients and then throw in the protein.
Cook in a skillet until cooked through, following the fajitas recipe.

How to Use Fajita Sauce with Beans

I created this fajita sauce recipe especially for these Vegetarian Fajitas, to provide big flavor without the need for meat. It works perfectly and brings in enough intrigue to elevate this plant-based protein to rockstar level. Here’s the basic concept for using it with beans:

Use pinto or black beans: Drain two 15-ounce cans beans. No need to rinse!
Heat 6 to 8 minutes in a skillet. Place the sauce and beans in a skillet, and cook until the sauce is thickened. It’s seriously easy.

Tip: Add Fajita Veggies

Need veggies to go with your fajitas recipe? My standard method is to broil them until charred, then finish them off in a sizzling skillet. Go to Classic Fajita Veggies.

What to Serve with Fajitas

Once you’ve made your fajitas, here few of my favorite ways to round out the meal:

Add warm flour or corn tortillas with Pico de Gallo and Simple Guacamole
Make a burrito bowl with Cilantro Lime Rice
Serve as a Fajita Salad for a lighter take
Alongside Spanish Rice

Storing The Sauce

Store leftover fajita sauce in a sealed jar in the refrigerator for up to 1 week. You can also freeze it for up to 1 month. Give it a good shake or whisk before using, since the oil and lime juice naturally separate.
