What You’ll Need
I’ve broken down the ingredients to keep things simple. You’ll have the steak and its marinade, and then the veggies and the glorious queso.
For the Steak & Marinade:
- 1.5 lbs flank or skirt steak, thinly sliced against the grain
- 2 tbsp olive oil
- 2 tbsp lime juice (fresh is best!)
- 1 tbsp Worcestershire sauce
- 2 cloves garlic, minced
- 1 tsp chili powder
- 1 tsp cumin
- 1/2 tsp smoked paprika
- 1/2 tsp dried oregano
- 1/2 tsp salt
- 1/4 tsp black pepper
For the Fajitas & Queso:
- 1 tbsp olive oil
- 1 large red bell pepper, sliced
- 1 large green bell pepper, sliced
- 1 large yellow onion, sliced
- 8 oz Monterey Jack cheese, freshly grated
- 4 oz sharp cheddar cheese, freshly grated
- 1/2 cup whole milk or heavy cream
- 1 (4-oz) can diced green chiles, undrained
- 1/4 cup chopped fresh cilantro, for garnish
Tools Required for the Job
You don’t need a lot of fancy equipment for this one, which is part of its charm.

- Large bowl or resealable plastic bag (for marinating)
- Sharp knife
- Cutting board
- Tongs

Pro Tips for a Perfect Skillet
I’ve made this dish more times than I can count. Here are a few hard-won tips that make a real difference.
1. Get That Pan Screaming Hot: Before you add the steak, let your skillet get seriously hot. A good sear locks in the juices and creates that amazing crust. You’ll know it’s ready when a drop of water sizzles and evaporates instantly.
2. Don’t Crowd the Pan: Cook the steak in batches. If you pile it all in at once, the pan’s temperature will drop, and you’ll end up steaming the meat instead of searing it. Give the steak slices some personal space.
3. Shred Your Own Cheese: This is non-negotiable for a silky smooth queso. Pre-shredded cheeses are coated with anti-caking agents that can make your sauce gritty. Grating a block of cheese only takes a minute and the result is worth it.
4. Slice Against the Grain: When you’re prepping your steak, look for the long muscle fibers running through the meat. You want to slice perpendicular to those lines. This simple step makes even tougher cuts of meat incredibly tender.
Step-by-Step Instructions
Alright, let’s get cooking. Follow these steps and you’ll have a masterpiece on your hands.
Step 1: Marinate the Steak
In a large bowl, whisk together the 2 tablespoons of olive oil, lime juice, Worcestershire sauce, minced garlic, and all the spices. Add the sliced steak and toss until it’s fully coated. Let it marinate for at least 30 minutes at room temperature, or up to 4 hours in the fridge.
Step 2: Sear the Steak
Heat your large cast-iron skillet over medium-high heat. Once it’s very hot, add the steak in a single layer (work in batches!). Cook for 2-3 minutes per side until nicely browned. Remove the steak from the skillet and set it aside.
Step 3: Cook the Veggies
Reduce the heat to medium and add the remaining 1 tablespoon of olive oil to the skillet. Add the sliced onions and bell peppers. Cook, stirring occasionally, for 6-8 minutes, until they are soft and slightly charred. All those brown bits from the steak on the bottom of the pan? That’s pure flavor!
Step 4: Make the Magical Queso
Reduce the heat to low. Push the vegetables to the sides of the skillet. Pour in the milk or cream and let it warm up for a minute. Gradually stir in the shredded Monterey Jack and cheddar cheeses, a handful at a time, stirring constantly until melted and smooth. Stir in the can of diced green chiles.
Step 5: Bring It All Together
Return the cooked steak to the skillet, nestling it into the queso and veggies. Let everything warm through for a minute or two. Sprinkle with fresh cilantro and serve immediately, right from the skillet.

Cooking Time Efficiency Tips
To get this on the table even faster, prep your ingredients while the steak marinates. You can also use pre-sliced peppers and onions from the grocery store to save a few minutes.
Meal Pairing Suggestions
While this skillet is a meal in itself, it plays well with others. Serve with warm tortillas, a side of cilantro-lime rice, or just a big spoon. A simple dollop of sour cream or guacamole on top is never a bad idea.
Substitutions and Variations
Feel free to get creative! This recipe is a great starting point.
- Protein Power: Not a steak fan? This works great with chicken thighs or shrimp. For a vegetarian option, try sliced portobello mushrooms or a can of drained black beans added with the veggies.
- Veggie Overload: Add some sliced zucchini, corn, or jalapeños along with the peppers and onions.
- Cheese Please: Mix it up with different cheeses. Pepper Jack adds a nice kick, while a blend of Asadero and Oaxaca will give you an amazing cheese pull.
- Spice It Up: For more heat, add a pinch of cayenne pepper to the marinade or throw a sliced jalapeño in with the vegetables.
Make-Ahead Tips
You can do most of the prep work ahead of time. Slice the steak and vegetables and store them in separate airtight containers in the fridge for up to 2 days. You can also mix the marinade ahead of time. When you’re ready to cook, it’ll come together in under 20 minutes.
Leftovers and Storage
If you somehow have leftovers, store them in an airtight container in the refrigerator for up to 3 days. The queso sauce will thicken as it cools.
To reheat, simply warm it gently in a skillet over low heat, stirring until heated through. You can add a splash of milk to loosen the sauce if needed.
Frequently Asked Questions
Here are some common questions that come up with this recipe.
Q1. What is the best cut of steak to use for fajitas?
Ans: Skirt steak is the classic choice because of its robust, beefy flavor. Flank steak is a great alternative that is a bit leaner. Both are best when sliced thinly against the grain.
Q2. My queso sauce turned out grainy. What went wrong?
Ans: This usually happens for two reasons: the heat was too high, or you used pre-shredded cheese. Always use low heat when melting cheese and shred it yourself from a block for the smoothest sauce.
Q3. Can I use a different type of pan besides cast iron?
Ans: Absolutely. Any heavy-bottomed skillet that can handle high heat will work. Stainless steel is a good option. Just avoid non-stick pans if you want to get a really good, hard sear on the steak.
Q4. How do I know when the steak is done?
Ans: Because the steak is sliced so thinly, it cooks very quickly. 2-3 minutes per side on high heat is usually perfect for a nice sear on the outside while keeping it tender inside. It will cook a little more when you add it back to the skillet at the end.
