What is halloumi?

Halloumi is a semi-hard, unripened cheese traditionally from Cyprus, usually made from sheep’s or goat’s milk (sometimes cow’s). Its high melting point makes it ideal for grilling or pan-frying—halloumi browns nicely while keeping its shape and chewy texture, making it a great meat alternative in dishes like fajitas.

How to Make Halloumi Fajitas

This simple, one-pan method gets dinner on the table fast.

Step 1: Mix the fajita seasoning

Combine the chili powder, paprika, cumin, salt, onion powder and garlic powder in a small bowl or jar. Stir well and set aside.

Step 2: Prep and season the halloumi

Slice the halloumi into strips. Combine half the fajita seasoning with 1 tablespoon of oil and rub it over the halloumi strips. Set aside while you prepare the vegetables.

Step 3: Sauté the fajita veggies

Slice the bell peppers and onion into thin strips. Heat oil in a large cast-iron or heavy skillet over high heat until shimmering. Add the veggies and cook, tossing occasionally, until they are tender-crisp with a bit of char—about 5–10 minutes depending on your preference. Stir in the remaining fajita seasoning and the dried oregano when the veggies are nearly done. Transfer the vegetables to a bowl and wipe the skillet clean.

Step 4: Pan-fry the halloumi

Return the skillet to medium heat and pan-fry the seasoned halloumi strips for a few minutes per side until they develop a golden-brown crust.

Helpful Tips

  • Prep ahead: Slice the peppers and onions and mix the seasoning ahead of time to speed up assembly.
  • Storage and reheating: Halloumi is best served fresh; leftovers keep 4–5 days in the fridge in an airtight container. Reheat briefly in a skillet to restore some texture.
  • Make a larger seasoning batch: Mix extra fajita seasoning and store it in a jar for quick use—this recipe uses about 2 tablespoons total.
  • Chili powder note: The recipe uses American-style chili powder (a mild blend). If your chili powder is pure ground chilies, reduce the amount to avoid excess heat.
