Irresistible Chicken Flautas with Spinach

I never thought much about flautas until I grabbed a bag of spinach that was about to go bad and needed to use it up fast. You know how it is—you buy greens with good intentions, and suddenly they’re wilting in your fridge three days later.

That’s when I remembered flautas are basically just rolled-up tortillas filled with whatever you’ve got on hand, then crisped up until they’re golden. I had leftover rotisserie chicken from dinner the night before, some cheese, and those sad spinach leaves. Turns out, that combination is actually really good together. The spinach cooks down to almost nothing, so you get a little green in there without it being overwhelming. And baking them instead of frying means you can pop them in the oven and walk away instead of standing over hot oil.

What Kind of Tortillas Should I Use?

For flautas, you’ll want to use flour tortillas rather than corn, as they’re more pliable and less likely to crack when you roll them up. The 6 to 8-inch size works perfectly – they’re small enough to roll tightly but big enough to hold a good amount of filling. If your tortillas seem a bit stiff from the fridge, warm them slightly in the microwave for about 10-15 seconds wrapped in a damp paper towel to make them easier to work with. Fresh tortillas from the bakery section tend to be softer and more flexible than the shelf-stable ones, but either will get the job done.

Options for Substitutions

This recipe is pretty straightforward, but here are some swaps you can make if needed:

• Flour tortillas: You can use corn tortillas instead, but warm them up first so they don’t crack when you roll them. They’ll give you a more traditional flauta texture and flavor.
• Rotisserie chicken: Any cooked chicken works here – leftover grilled chicken, poached chicken breasts, or even canned chicken in a pinch. You can also swap in cooked turkey or shredded pork.
• Fresh spinach: Frozen spinach is a great substitute – just thaw it completely and squeeze out all the excess water before using. You’ll need about ½ cup of frozen spinach to replace the fresh.
• Monterrey Jack or Pepper Jack cheese: Cheddar, mozzarella, or a Mexican blend all work well. If you want more heat, go with Pepper Jack, or mix in some crumbled queso fresco for a different flavor.
• Oil spray: If you don’t have spray, you can brush the flautas with regular olive oil or melted butter before cooking.

Watch Out for These Mistakes While Cooking

The biggest mistake when making flautas is not removing enough moisture from the spinach after wilting it, which can make your tortillas soggy and cause them to fall apart – squeeze the spinach in a clean kitchen towel or paper towels until barely any liquid comes out.

Skipping the oil spray or using too little will leave you with pale, soft flautas instead of crispy, golden ones, so make sure to coat them generously on all sides.

Another common error is overfilling the tortillas, which makes them impossible to roll tightly and causes the filling to burst out during baking – stick to about 1/3 cup of filling per tortilla and leave space at the edges.

Finally, don’t skip flipping them halfway through baking, as this ensures both sides get equally crispy and prevents one side from staying soft.

What to Serve With Chicken Flautas?

These crispy chicken flautas are perfect with a side of Mexican rice and refried beans for a complete meal that feels like you ordered takeout. I love setting up a little topping bar with sour cream, guacamole, salsa, and some shredded lettuce so everyone can customize their flautas however they like. A simple side salad with lime vinaigrette also works great to balance out the richness of the cheese, or you could go with some elote (Mexican street corn) if you want to keep the fiesta vibes going. For a lighter option, just serve them with a big bowl of pico de gallo and some lime wedges for squeezing.

Storage Instructions

Store: Keep leftover flautas in an airtight container in the fridge for up to 3 days. They’re great for quick lunches or snacks throughout the week, and the flavors actually meld together nicely after a day or two.

Freeze: These flautas are perfect for freezing! You can freeze them either before or after baking. If freezing unbaked, arrange them on a baking sheet until solid, then transfer to a freezer bag for up to 3 months. For already-baked flautas, let them cool completely before freezing the same way.

Reheat: Pop refrigerated flautas in a 350°F oven for about 10 minutes until warmed through and crispy again. If baking from frozen, add an extra 5-10 minutes to the cooking time. You can also use an air fryer at 375°F for 5-7 minutes for a super crispy result.

• Calories: 1250-1400

• Fat: 55-65 g
• Carbohydrates: 120-135 g

Ingredients

• 6 flour tortillas (Mission Soft Taco size)
• 3.5 oz spinach (roughly chopped into 1/2-inch strips)
• 8 oz shredded rotisserie chicken
• 7 oz Monterey Jack cheese (freshly grated from a block)
• 1/2 teaspoon ground cumin
• 1/4 teaspoon garlic powder
• olive oil spray (for coating)

Step 1: Prepare the Oven and Mise en Place

• 3.5 oz spinach, roughly chopped into 1/2-inch strips
• 8 oz shredded rotisserie chicken
• 7 oz Monterey Jack cheese, freshly grated
• 1/2 teaspoon ground cumin
• 1/4 teaspoon garlic powder

Preheat your oven to 450°F.

While the oven heats, prepare all your components: chop the spinach into roughly 1/2-inch strips, shred the rotisserie chicken if not already done, and grate the Monterey Jack cheese from a block (pre-shredded cheese contains anti-caking agents that prevent it from melting smoothly).

In a small bowl, combine the ground cumin and garlic powder.

Having everything ready before assembly ensures your filling stays at the right temperature and the flautas cook evenly.

Step 2: Wilt the Spinach and Remove Moisture

• 3.5 oz spinach, roughly chopped into 1/2-inch strips

Heat a large skillet over medium-high heat and add the chopped spinach directly to the dry pan (no oil needed).

Stir occasionally for 2-3 minutes until the spinach is completely wilted and releases its moisture.

Transfer the wilted spinach to a fine-mesh strainer or clean kitchen towel and press firmly to squeeze out as much liquid as possible—this step is crucial to prevent soggy, leaking flautas.

The drier the spinach, the crispier your finished flautas will be.

Step 3: Mix the Filling

• wilted spinach from Step 2
• 8 oz shredded rotisserie chicken
• 7 oz Monterey Jack cheese, freshly grated
• cumin-garlic powder mixture from Step 1

In a medium bowl, combine the squeezed spinach from Step 2 with the shredded rotisserie chicken, grated Monterey Jack cheese, and the cumin-garlic powder mixture from Step 1.

Toss gently with your hands or a fork until evenly distributed.

I like to taste a small pinch here and adjust the seasoning if needed—sometimes the rotisserie chicken is already well-seasoned, so you may want to add a tiny pinch of salt or hold back on the spices.

Don’t overmix, as you want distinct pockets of flavor in each flauta.

Step 4: Warm and Fill the Tortillas

• 6 flour tortillas
• filling mixture from Step 3

Warm the flour tortillas in a dry skillet over medium heat for about 30 seconds per side, or wrap them in a damp paper towel and microwave for 15-20 seconds.

Warm tortillas are pliable and won’t crack when rolled.

Place a tortilla on a clean work surface and spoon about 3-4 tablespoons of the filling mixture from Step 3 down the center, leaving roughly 1 inch of space on all sides.

Roll the tortilla tightly away from you, tucking in the sides as you go to create a secure package.

Repeat with the remaining tortillas and filling.

Step 5: Prepare the Baking Sheet and Arrange Flautas

• rolled flautas from Step 4
• olive oil spray

Line a baking sheet with parchment paper or lightly spray it with olive oil.

Arrange the rolled flautas seam-side down on the prepared sheet, spacing them about an inch apart so they cook evenly and the sides can get crispy.

Lightly spray the tops and sides of each flauta with olive oil—a light coating is all you need for them to turn golden and crispy in the oven.

Step 6: Bake and Flip for Even Crisping

• flautas from Step 5

Bake the flautas in your preheated 450°F oven for 8 minutes.

The bottoms should be golden and crispy.

Carefully flip each flauta over using a spatula and bake for another 5-8 minutes until the second side is equally golden and crispy.

I like to give mine an extra minute or two past the 5-minute mark to ensure they’re really crispy all over—this gives you that satisfying crunch when you bite into them.

Watch toward the end of cooking to prevent over-browning.

Step 7: Serve

Transfer the hot, crispy flautas to a serving platter.

Serve immediately with your choice of toppings such as sour cream, guacamole, salsa, or fresh cilantro.
