How to Make Cheese Steak Fajitas
-
Marinate Steak: In a bowl, mix lime juice, olive oil, minced garlic, chili powder, cumin, and smoked paprika. Add the flank steak, ensuring it is well coated. Let it marinate for at least 30 minutes to enhance the flavor.
-
Prep Vegetables: Slice bell peppers and onions into ¼-inch strips. This will help them cook evenly and caramelize nicely. Set them aside at room temperature while your steak marinates.
-
Cook Steak: Preheat your skillet over high heat until smoking. Once hot, pat the steak dry and sear it without moving it for 4-5 minutes to form a crust. Flip and cook for another 3-4 minutes for a medium-rare finish. Rest for 10 minutes, then slice against the grain for ultimate tenderness.
-
Caramelize Vegetables: In the same skillet, add a splash of olive oil and start with the onions. Sauté for about 4 minutes until they begin to soften. Then, toss in the bell peppers and season with salt and pepper. Cook until they’re charred and tender, about 8-10 minutes.
-
Make Queso Sauce: In a saucepan, melt butter over medium heat and whisk in flour to form a roux. Gradually add milk while whisking continuously until smooth. Stir in cheddar cheese until melted and creamy. If you’re feeling adventurous, add some jalapeños for an extra kick!
-
Assemble Stack: Warm your tortillas briefly in a skillet or microwave. On each tortilla, layer with sliced steak, caramelized vegetables, and drizzle generously with the queso sauce. Repeat for a delicious stack and serve warm, garnished with sour cream and pico de gallo if desired.
Optional: Garnish with fresh cilantro for an added burst of freshness!

How to Store and Freeze Cheese Steak Fajitas
Refrigerator: Store leftovers in an airtight container for up to 3 days. Keep the steak, vegetables, and queso separate to maintain freshness.
Freezer: For longer storage, freeze the marinated steak for up to 3 months. Thaw in the fridge overnight before cooking, or cook and freeze assembled stacks for easy reheating.
Reheating: Gently reheat components in a skillet over low heat, adding a splash of water to keep it moist. Assemble fresh while reheating for the best texture.
Assembly Tip: For optimal taste, enjoy your Cheese Steak Fajitas fresh. Assemble only what you’ll eat immediately, saving the rest for later!
Tips for the Best Cheese Steak Fajitas

Warm Tortillas: Heating your tortillas helps them stay pliable and prevents tearing. Wrap them in a damp paper towel and microwave for a few seconds.

Cheese Steak Fajitas Recipe FAQs
How do I choose the best flank steak?
Absolutely! When selecting flank steak, look for a piece that is bright red with a good amount of marbling. Avoid any with dark spots or excessive liquid packaging. For the best flavor, choose grass-fed if you can!
What’s the best way to store leftovers?
To keep your Cheese Steak Fajitas fresh, store them in an airtight container in the refrigerator for up to 3 days. Be sure to keep the steak, vegetables, and queso sauce separate to avoid sogginess, and reheat gently on the stove.
Can I freeze the marinated steak?
Yes! For optimal flavor, marinate the flank steak and then freeze it in a zip-top bag for up to 3 months. When you’re ready to cook, thaw the steak overnight in the refrigerator. It’s a time-saver for busy nights!
What if my steak turns out tough?
Very good question! To avoid tough steak, always slice it against the grain—this is critical! Additionally, ensure you don’t overcook the steak; medium-rare is ideal for tenderness, so use a meat thermometer to check for about 130°F (54°C).
Can I make this recipe dairy-free?
Absolutely! Swap out the cheddar cheese with a dairy-free alternative like nutritional yeast and use coconut milk for the queso sauce. You can also try a cashew cream for a rich texture without the dairy, making it a versatile option for a variety of diets.
How do I prevent my vegetables from getting mushy?
To achieve beautifully caramelized vegetables, it’s key not to overcrowd the pan. Cook them in batches if necessary and ensure your skillet is hot—this helps them char rather than steam, giving you that delightful crispy texture!
