• Oven baking melts the cheese perfectly and warms tortillas evenly
• Family-friendly flavors that work for weeknight dinners

Ingredients

For the sauce:

• 1/4 cup sour cream (room temperature for smooth blending)
• 1 tbsp canned green chilis (finely chopped)
• 1/4 tsp ground cumin (freshly ground preferred for more flavor)
• salt to taste
• 1.5 tbsp all-purpose flour (I prefer King Arthur)
• 1/4 tsp chili powder
• black pepper to taste
• 1/2 cup skim milk
• 1/2 cup chicken broth
• 1 tbsp unsalted butter (I use Kerrygold for richness)

For the filling:

• 1/4 cup green onions (thinly sliced, about 1/8-inch pieces)
• 8 oz shredded chicken (cooked and cooled)
• 3/4 cup frozen corn (I use Birds Eye)

For assembly:

• 14 small corn tortillas (warmed before serving)
• 3.5 oz shredded mozzarella cheese

Step-by-Step Instructions

1. Preheat your oven to 400°F. While the oven heats, prepare all ingredients by measuring the milk, chicken broth, sour cream, flour, and spices. Finely chop the green chilis, thinly slice the green onions into 1/8-inch pieces, and have the cooked, cooled shredded chicken and frozen corn ready. This organized prep ensures the cooking process moves smoothly.
2. Place a medium saucepan over medium heat and add the unsalted butter. Once the butter has melted and looks foamy, whisk in the flour. Cook the mixture for about 1 minute, stirring constantly, until a light roux forms without browning.
3. Slowly whisk in the skim milk and chicken broth together, pouring gradually to prevent lumps. Add the room-temperature sour cream and continue whisking until the sauce is completely smooth and cohesive.
4. Add the ground cumin, finely chopped green chilis, chili powder, salt, and black pepper. Reduce the heat to medium-low and simmer the sauce for 3–5 minutes, stirring occasionally, until it thickens enough to lightly coat the back of a spoon. Taste and adjust seasoning as needed.
5. In a medium bowl, combine the shredded chicken, frozen corn, and sliced green onions. Pour the warm sauce over the mixture and stir until all ingredients are evenly coated. Let the filling rest briefly so the flavors can meld.
6. Warm the corn tortillas in a dry skillet over medium-low heat for about 30 seconds per side, just until pliable. Place a tortilla on your work surface, spoon about 3 tablespoons of filling down the center, sprinkle with roughly 1/2 ounce of shredded mozzarella cheese, and fold gently into a taco shape.
7. Arrange the filled tacos seam-side up on a parchment-lined baking sheet. Transfer to the preheated oven and bake for 12–15 minutes, until the cheese is fully melted and the tortilla edges turn lightly golden.
8. Remove from the oven and allow the tacos to cool for 1–2 minutes before serving. Serve warm while the cheese is soft and stretchy.

Expert Tips for Best Results

Using room-temperature sour cream is key for a smooth sauce. Cold sour cream can cause the sauce to seize or separate when added to the hot liquid.

Whisk continuously when adding the milk and broth. Slow, steady whisking prevents lumps and ensures a velvety texture.

Avoid over-reducing the sauce. It will continue to thicken slightly as it cools, so stop simmering once it lightly coats a spoon.

Warming tortillas before filling makes them flexible and less likely to crack during baking.

Flavor Variations and Custom Ideas

• Serve with fresh salsa or pico de gallo on the side for brightness
• Add sliced jalapeños as a topping for extra heat
• Finish with a drizzle of sour cream before serving
• Pair with a simple green salad for balance
• Offer lime wedges at the table for a fresh squeeze

Storage and Reheating

Store leftover filling separately from tortillas in an airtight container in the refrigerator for up to 3 days. Keeping components separate helps preserve texture.

To reheat, warm the filling gently on the stovetop or in the microwave, then assemble fresh tacos and bake briefly until heated through.

Frequently Asked Questions

Can I make the filling ahead of time?

Why should sour cream be room temperature?
It blends smoothly into the sauce and prevents curdling.

Can I freeze the filling?
Freezing is not recommended, as the sour cream sauce may separate when thawed.

How do I keep tortillas from cracking?
Warming them before filling makes them pliable and easier to fold.

Can I bake the tacos longer for extra crispness?
Yes, but watch closely to avoid over-drying the tortillas.
