Ingredients You’ll Need

You will need the following ingredients to make these halloumi vegetable fajitas…

Fajita Seasoning: This homemade fajita seasoning is a blend of six spices: chili powder, paprika, cumin, salt, onion powder and garlic powder. Cayenne pepper is an optional ingredient if you like a little extra heat.
Avocado Oil: For sautéing the veggies and creating a spice marinade for the halloumi slices. I like to use avocado oil in this recipe since it is a healthy oil with a neutral taste and high smoke point.
Veggies: Sliced bell peppers and onions to make fajita veggies. I like to use a variety of different colored peppers for visual appeal.
Dried Oregano: Gets added to the veggies for flavor.
Halloumi: The star of these fajitas!
For serving: Serve with tortillas (flour or corn) and your favorite toppings (salsa, guacamole, sour cream, chopped green onions, lime wedges, hot sauce, etc.).

What is halloumi?

Halloumi is a semi-hard, unripened, brined cheese that originates from Cyprus. It’s typically made from sheep’s or goat’s milk (or a combo of the two) but cow’s milk is also sometimes used today.

Now here’s the magical part! Halloumi has a high melting point which means that it can be pan fried or grilled without melting. This feature makes it a popular substitute for meat in many recipes like these fajitas or this Halloumi Stroganoff recipe.

How To Make Halloumi Fajitas

These Halloumi Vegetable Fajitas are quick and easy to make. Dinner will be on the table in no time!

Step 1: Mix Together Fajita Seasoning

Combine all the fajita seasoning ingredients in a small bowl or jar and set aside.

Step 2: Prep + Season Halloumi

Cut halloumi into strips. Mix together half of the fajita seasoning with 1 tablespoon of oil and rub it all over the halloumi strips. Set aside.

Step 3: Sauté Fajita Veggies

Slice the bell peppers and onion into thin strips. Heat oil in a large cast iron skillet over high heat until shimmering. Add the veggies and sauté until tender crisp with a bit of charring (approx. 5-10 minutes depending on how soft you want them). When the veggies are almost done cooking, stir through the other half of the fajita seasoning and the dried oregano. Transfer to a bowl and wipe the skillet clean.

Step 4: Pan Fry Halloumi Strips

In the same skillet over medium heat, pan fry the seasoned halloumi strips for a few minutes on each side until golden brown.

Helpful Tips

Prep Ahead: Speed things up at dinner time by having the veggies already pre sliced and the fajita seasoning mixed together.
Storage + Reheating: Halloumi is best served immediately since it just doesn’t have the same amazing texture when reheated. Therefore, I wouldn’t recommend fully meal prepping this dish in advance. Any leftovers can be stored in the fridge for up to 4-5 days in an airtight container and quickly reheated in a pan before serving.
Make a big batch of seasoning: Double, triple or quadruple the homemade fajita seasoning and store it in a jar so that it is ready to use anytime you want to make fajitas. To make this recipe, you would just need to measure out 2 tablespoons from your jar.
Chili Powder: Just a friendly warning for my international friends that the chili powder being used in this recipe refers to the American style chili powder which is a blend and not very spicy. It is NOT just purely ground up chilis. Your mouth will be on fire if you mix them up!
