Easy Skirt Steak Quesadilla

If you ask me, quesadillas are one of life’s simple pleasures.

These skirt steak quesadillas bring together the best of Mexican street food right in your own kitchen. Tender, grilled strips of beef mingle with melted cheese between crispy tortillas, creating a meal that’s both satisfying and straightforward.

I love how the meat gets those nice charred edges while staying juicy inside, and when you add some fresh onions and cilantro, it takes on that authentic taco truck flavor we all know and love.

It’s a no-fuss dinner that’s guaranteed to get the family gathering around the table, perfect for those busy weeknights when you want something that feels special without too much work.

What Kind of Steak Should I Use?

While this recipe calls for either skirt or flank steak, there are some key differences to keep in mind. Skirt steak tends to have more intense beef flavor and is slightly thinner than flank steak, making it ideal for quick-cooking methods. Flank steak is a bit leaner and has a more pronounced grain pattern, but it’s equally delicious in quesadillas. Whichever cut you choose, remember to slice it against the grain – this means cutting perpendicular to the muscle fibers, which helps keep the meat tender and easy to bite through. For the best results, look for meat that’s bright red with minimal surface moisture, and try to get a piece that’s even in thickness throughout.

Options for Substitutions

This quesadilla recipe is pretty flexible and you can make several swaps based on what you have in your kitchen:

• Skirt or flank steak: While these cuts are ideal for quesadillas, you can also use sirloin, flat iron steak, or even leftover cooked steak. If you’re not into beef, try chicken breast or thigh meat – just adjust cooking time accordingly.
• Cheese blend: Don’t have mozzarella and Monterey Jack? That’s okay! Try cheddar, pepper jack, or Oaxaca cheese. Just make sure to use cheese that melts well. Avoid hard aged cheeses as your main cheese as they won’t give you that gooey texture.
• Flour tortillas: While flour tortillas are traditional for quesadillas, corn tortillas work too – just warm them slightly first so they’re more pliable. For a low-carb option, try large lettuce leaves, but know the texture will be very different.
• Seasonings: Out of specific seasonings? Use what you have! Taco seasoning works great as a substitute for the individual spices. If you don’t have onion or garlic seasoning, use powder versions – just use half the amount.
• Olive oil: Any neutral cooking oil works here – vegetable oil, canola oil, or even butter will do the job just fine.

Watch Out for These Mistakes While Cooking

The biggest challenge when making steak quesadillas is overcooking the skirt steak – this cut should be cooked to medium-rare (135°F) and sliced against the grain to ensure tenderness, not toughness. A common error is flipping the quesadillas too frequently while cooking; instead, wait until the cheese starts melting and the bottom tortilla turns golden brown before attempting one careful flip. To prevent your quesadillas from becoming greasy, avoid overloading them with cheese – about 1/2 cup total per quesadilla creates the perfect balance while ensuring everything stays together when flipped. For the crispiest results, cook your quesadillas on medium heat (not high), and resist the urge to press down on them with your spatula, which can force out the melted cheese and create a mess on your griddle.

What to Serve With Steak Quesadillas?

These cheesy steak quesadillas pair perfectly with classic Mexican-style sides that’ll make your meal feel like a real fiesta! A simple bowl of Mexican rice with some black or pinto beans makes for a filling and tasty combination. I love to put out a spread of toppings like fresh pico de gallo, shredded lettuce, and pickled jalapeños so everyone can customize their plate. For a lighter option, try serving these quesadillas with a crisp Mexican-style coleslaw dressed with lime juice and cilantro, or a simple corn salad with cherry tomatoes and avocado chunks.

Storage Instructions

Keep Fresh: Already assembled quesadillas will stay good in the fridge for up to 3 days. Place them in an airtight container with wax paper between each quesadilla to prevent sticking. If you want to prep ahead, you can cook and slice the steak and store it separately from the other ingredients – it’ll keep for up to 4 days in the fridge.

Freeze: These quesadillas are perfect for freezing! Let them cool completely, then wrap each one individually in foil and pop them in a freezer bag. They’ll stay good for up to 3 months. Just remember to freeze them before adding any toppings like salsa or sour cream.

Warm Up: To get your quesadillas crispy again, warm them in a skillet over medium heat for about 2-3 minutes per side. If they’re frozen, let them thaw in the fridge overnight first. You can also use the oven at 350°F for about 10 minutes, or until the cheese is melty again.

Ingredients

For the steak:

• 1 1/2 tbsp olive oil (I use Colavita extra virgin olive oil)
• 1/2 tsp cumin
• 2 tsp kosher salt
• 1 tsp onion seasoning
• 1/2 tsp garlic seasoning
• 1 tsp black pepper
• 1 lb flank or skirt steak (for best flavor, choose skirt steak)

For the quesadillas:

• 1 medium onion (thinly sliced)
• 10 medium flour tortillas (8-inch, Mission brand works well)
• 2 1/2 cups shredded mozzarella cheese
• 1/2 tbsp olive oil
• 2 1/2 cups shredded Monterey Jack cheese (melts beautifully)

For serving:

• salsa
• sour cream
• guacamole

Step 1: Season and Cook the Steak

Begin by heating a large skillet over medium-high heat.

While the skillet is heating, pat the steak dry on both sides using paper towels.

In a small bowl, mix together salt, onion powder, black pepper, cumin, and garlic powder.

Evenly sprinkle this seasoning mix over both sides of the steak.

Add 1 1/2 tablespoons of olive oil to the hot skillet, then add the seasoned steak.

Cook it for about 4-8 minutes on each side, depending on the thickness of the steak and your desired level of doneness.

Once cooked, remove the steak from the skillet and transfer it to a cutting board to rest.

Step 2: Cook the Onions

While the steak is resting, add the remaining 1/2 tablespoon of olive oil to the skillet.

Add the sliced onions and cook them, stirring occasionally, for approximately 8 minutes until they soften.

After cooking, transfer the onions to a bowl and carefully wipe the inside of the skillet clean with a few paper towels.

Set the skillet aside for later use.

Step 3: Prepare the Steak and Cheese

Uncover the rested steak and slice it against the grain at an angle into thin slices or bite-sized chunks.

In a medium bowl, combine the shredded mozzarella and Monterey Jack cheeses, mixing them thoroughly.

Step 4: Assemble the Quesadillas

Begin assembling the quesadillas by placing 1/2 cup of the shredded cheese mixture on one tortilla.

Add the sliced steak and cooked onions, then top with another 1/2 cup of cheese.

Sprinkle a pinch of salt over the top before placing another tortilla on top to complete the quesadilla.

Step 5: Cook the Quesadillas

Return the clean skillet to the stove over medium heat.

Using a spatula, carefully transfer the assembled quesadilla to the skillet.

Cook for 1-2 minutes or until the bottom of the quesadilla is golden-brown.

Gently flip the quesadilla and cook for an additional 1-2 minutes until the other side is golden-brown and the cheese has melted completely.

Repeat this process for the remaining quesadillas.

Step 6: Serve and Enjoy

Serve the quesadillas immediately as is, or cut them into fourths for easier eating.

Accompany with salsa, guacamole, and sour cream for added flavor.
