Ingredients

  • 1/2 cup (1 stick) unsalted butter, softened
  • 1 teaspoon smoked paprika
  • 1 teaspoon ground cumin
  • 1 teaspoon chili powder
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon cayenne pepper (adjust to taste)
  • 1 teaspoon dried oregano (preferably Mexican oregano)
  • 1 tablespoon fresh lime juice
  • 1 teaspoon finely chopped fresh cilantro (optional)
  • Salt and black pepper to taste

Equipment

  • Mixing bowl for combining ingredients
  • Measuring spoons for spices and liquids
  • Spoon or spatula for mixing
  • Plastic wrap or parchment paper for shaping the butter
  • Knife to chop cilantro
  • Refrigerator for setting the butter
  • Skillet or grill pan for cooking fajitas

Instructions

  1. Soften the butter: Remove the butter from the fridge and let it sit at room temperature for about 20-30 minutes until soft but not melted.
  2. Mix the spices: In a small bowl, combine the smoked paprika, ground cumin, chili powder, garlic powder, onion powder, cayenne pepper, dried oregano, salt, and black pepper.
  3. Combine butter and spices: Add the softened butter to a larger mixing bowl. Add the spice mixture and fresh lime juice. Using a spoon or spatula, mix thoroughly until all the spices are evenly incorporated into the butter.
  4. Add fresh herbs: Stir in the chopped cilantro if using. This adds a fresh, vibrant note to the butter.
  5. Shape the butter: Lay out a piece of plastic wrap or parchment paper. Transfer the spiced butter mixture onto the wrap and shape it into a log or block, about 1 inch in diameter. Wrap it tightly to prevent air from getting in.
  6. Chill the butter: Refrigerate the wrapped butter for at least 1 hour to firm up. For longer storage, place it in the freezer for up to 3 months.
  7. Use on fajitas: When ready to cook, slice off rounds of the Mexican butter and melt it in your skillet or grill pan before adding your fajita meat and vegetables. This will infuse your fajitas with rich, smoky flavor and help them caramelize beautifully.

Tips & Variations

For the best flavor, use high-quality unsalted butter and fresh spices. Toasting your cumin and chili powder briefly in a dry pan before mixing can intensify their aroma.

  • Make it spicy: Add extra cayenne pepper or a pinch of chipotle powder for smoky heat.
  • Herb variations: Swap cilantro for fresh parsley or add a teaspoon of chopped fresh thyme for a different herbal twist.
  • Garlic lovers: Mince 1-2 cloves of fresh garlic and mix into the butter for a sharper garlic flavor.
  • Butter alternatives: Try using ghee or clarified butter for a nuttier flavor and higher smoke point.
  • Vegan option: Use a plant-based butter substitute and adjust seasoning to taste.
