Ingredients

• For the Steak & Marinade:
• 1.5 lbs flank steak or sirloin steak, about 1-inch thick
• 2 tablespoons olive oil
• 4 cloves garlic, minced
• 1 teaspoon smoked paprika
• 1 teaspoon ground cumin
• 1 teaspoon dried oregano
• 1 teaspoon coarse sea salt
• 1/2 teaspoon black pepper
• For the Avocado Chimichurri:
• 1 large ripe avocado, pitted and scooped
• 1 cup packed fresh flat-leaf parsley
• 1/2 cup packed fresh cilantro
• 4-5 cloves garlic, roughly chopped
• 1/4 cup red wine vinegar
• 1/2 cup extra virgin olive oil
• 1 tablespoon fresh lime juice
• 1 teaspoon dried oregano
• 1/2 teaspoon red pepper flakes (adjust to your spice preference)
• 1/2 teaspoon coarse sea salt
• 1/4 teaspoon black pepper
• For the Quesadillas:
• 8 large flour tortillas (10-inch)
• 3 cups shredded Monterey Jack or a Mexican cheese blend
• 1/2 cup finely diced red onion
• 1 tablespoon butter or neutral oil, for cooking

Instructions

1. Prepare and Cook the Steak: Pat the steak dry with paper towels to ensure a perfect sear. In a small bowl, mix together the 2 tablespoons of olive oil, minced garlic, smoked paprika, cumin, dried oregano, salt, and black pepper. Rub this mixture evenly over all surfaces of the steak. For best results, let the steak marinate at room temperature for 30 minutes, or covered in the refrigerator for up to 4 hours.
2. Sear the Steak: Heat a large cast-iron skillet or grill pan over medium-high heat. The pan should be very hot. Add the steak and cook for 4-6 minutes per side for medium-rare, depending on the thickness of your cut. The key is to develop a deep, brown crust. Avoid moving the steak too much as it cooks to allow this crust to form.
3. Rest the Steak: This is a crucial step! Transfer the cooked steak to a cutting board and let it rest for at least 10 minutes. This allows the juices to redistribute throughout the meat, ensuring every bite is tender and flavorful. Tenting it loosely with foil can help keep it warm.
4. Make the Avocado Chimichurri: While the steak is resting, prepare the sauce. In the bowl of a food processor, combine the avocado, fresh parsley, cilantro, chopped garlic, red wine vinegar, lime juice, oregano, red pepper flakes, salt, and pepper. Pulse a few times to break everything down. Then, with the processor running on low, slowly stream in the 1/2 cup of extra virgin olive oil until the sauce is smooth and creamy. Scrape down the sides of the bowl as needed. Taste and adjust seasoning if necessary—it should be bright, tangy, and garlicky.
5. Slice the Steak: After the steak has rested, slice it thinly against the grain. Look for the lines running through the meat and cut perpendicular to them. This shortens the muscle fibers, making the steak incredibly tender to eat. Once sliced, you can chop the strips into smaller, bite-sized pieces perfect for a quesadilla filling.
6. Assemble the Quesadillas: Lay a tortilla flat. On one half of the tortilla, sprinkle a generous layer of shredded cheese. Top the cheese with a layer of the sliced steak and a sprinkle of diced red onion. Do not overfill, or the quesadilla will be difficult to flip and the filling will spill out.
7. Cook the Quesadillas: Heat a large non-stick skillet or griddle over medium heat. Add a small amount of butter or oil. Carefully place the assembled tortilla in the pan. Fold the empty half of the tortilla over the filled half. Cook for 2-4 minutes per side, until the tortilla is golden brown and crispy and the cheese is completely melted. Press down gently with a spatula to help it seal.
8. Serve Immediately: Remove the quesadilla from the skillet and place it on a cutting board. Let it rest for a minute before cutting it into wedges with a pizza cutter or sharp knife. Serve hot, with a generous amount of the Avocado Chimichurri on the side for dipping or drizzled over the top. Repeat the process with the remaining tortillas and filling.

How to Serve

• The Star of the Show: Serve the quesadilla wedges on a large platter with a big bowl of the Avocado Chimichurri in the center for communal dipping. This is perfect for parties or family-style meals.
• Classic Toppings: Offer bowls of sour cream (or plain Greek yogurt for a healthier tang), fresh pico de gallo, or your favorite salsa on the side.
• With a Fresh Salad: Balance the richness of the quesadillas with a simple side salad. A bed of mixed greens with a light lime vinaigrette is the perfect complement.
• Add a Side of Grains or Beans: For a more substantial meal, serve alongside a scoop of cilantro-lime rice or seasoned black beans.
• Garnish Generously: Finish with a sprinkle of fresh cilantro, some extra diced red onion, or a few slices of jalapeño for those who like extra heat. A squeeze of fresh lime over everything just before serving brightens all the flavors.

Additional Tips

• Choose the Right Steak: Flank steak and sirloin are excellent choices because they are flavorful and cook quickly. Skirt steak is another great option. The key is to not overcook it and to slice it thinly against the grain for maximum tenderness.
• Don’t Skip the Resting Step: Letting the steak rest for 10 minutes before slicing is non-negotiable. Cutting into it too soon will cause all the delicious juices to run out onto your cutting board, resulting in dry, tough meat. Patience pays off!
• Prevent Soggy Quesadillas: Ensure your steak and any other fillings are not overly wet. Pat the steak dry after cooking if needed. Also, don’t put the chimichurri sauce *inside* the quesadilla before cooking; its moisture content can make the tortilla soggy. Always serve it on the side for dipping or spoon it on top after cooking.
• Cheese Matters: While a pre-shredded Mexican blend is convenient, grating your own cheese from a block of Monterey Jack, Oaxaca, or Asadero will yield a much better melt. Pre-shredded cheeses are often coated in starches that prevent them from melting as smoothly.
• Make-Ahead Components: To save time, you can make the Avocado Chimichurri up to a day in advance. To prevent it from browning, press a piece of plastic wrap directly onto the surface of the sauce before sealing the container. You can also marinate the steak for up to 24 hours in the refrigerator.

Budgeting the Recipe

Creating a gourmet-style meal like these Chimichurri Steak Quesadillas doesn’t have to break the bank. With a few smart strategies, you can manage the cost effectively while still enjoying a delicious, high-quality dish. Steak is often the most expensive component, so focus your savings efforts there. Look for deals on flank or sirloin steak at your local butcher or supermarket. These cuts often go on sale. Alternatively, consider more budget-friendly cuts like skirt steak or flat iron steak, which are incredibly flavorful and become very tender when marinated and sliced correctly against the grain.

Another area for savings is in the fresh ingredients. Herbs like parsley and cilantro can be purchased in large bunches for a low price, and you can use any leftovers for other meals throughout the week. To maximize their lifespan, store them upright in a jar with a little water, like a bouquet of flowers. When it comes to cheese, buying a block and shredding it yourself is almost always cheaper per ounce than buying pre-shredded bags. It also melts better, giving you a superior final product. Finally, making a larger batch of this recipe can be very cost-effective. The ingredients scale well, and leftovers make for a fantastic lunch the next day, saving you money on another meal.

Frequently Asked Questions

Q: Can I use a different protein instead of steak?

A: Absolutely! This recipe is incredibly versatile. Grilled chicken thighs or breast would be a fantastic substitute. Simply season the chicken with the same spice rub and cook it through before dicing. Grilled shrimp would also be delicious. For a vegetarian option, you could use portobello mushrooms (sliced and sautéed with the same spices) or a hearty filling of black beans and corn.

Q: How should I store and reheat leftovers?

A: Store the leftover cooked quesadillas, sliced steak, and avocado chimichurri in separate airtight containers in the refrigerator for up to 3 days. The best way to reheat the quesadillas is in a dry skillet over medium-low heat or in an air fryer for a few minutes. This will re-crisp the tortilla. Microwaving is not recommended as it will make the tortilla soft and soggy.

Q: My avocado chimichurri turned brown. How can I prevent this?

A: The browning is due to oxidation. The lime juice and vinegar in the recipe help slow this process down, but to prevent it further, press a piece of plastic wrap directly against the entire surface of the chimichurri before putting the lid on your container. This minimizes contact with air. If it does brown slightly on top, you can often just scrape off the top layer to reveal the bright green sauce underneath.

Q: What is the best pan to use for making quesadillas?

A: A large, flat-bottomed pan is ideal. A well-seasoned cast-iron skillet works wonders as it distributes heat evenly and helps create a crispy, golden-brown crust. A non-stick skillet is also an excellent, easy-to-use option that prevents sticking and makes flipping a breeze. A flat-top griddle is perfect if you are making multiple quesadillas at once.

Q: Can I make this recipe gluten-free?

A: Yes, it’s very easy to adapt. The steak, marinade, and chimichurri are all naturally gluten-free. The only component you need to swap is the tortillas. Simply use your favorite brand of gluten-free tortillas or traditional corn tortillas instead of flour tortillas to make the recipe completely gluten-free and equally delicious.
