Step-by-Step Instructions

Prepare the Oven and Pan

Preheat your oven to 375°F (190°C) to ensure it reaches the proper temperature before the casserole goes in. Starting with a fully heated oven helps the dish cook evenly from the beginning, allowing the flavors to meld together while the cheese melts perfectly on top. While the oven is heating, lightly grease a 9×13-inch (23×33 cm) baking dish with olive oil or nonstick spray. Make sure to coat the bottom and sides thoroughly to prevent sticking and to make serving and cleanup easier later.

Using the correct size baking dish is important. A 9×13-inch pan allows the layers to spread evenly without becoming too thick, ensuring consistent baking throughout. If the pan is too small, the casserole may take longer to heat through; if it’s too large, the layers may become too thin and dry out more quickly. Taking a moment to properly prepare your pan sets the foundation for a successful casserole.

Sauté the Aromatics

Heat 2 tablespoons of olive oil in a skillet over medium heat. Once the oil is warm and shimmering, add the diced onion (about 1 cup from 1 medium onion). Cook for 4–5 minutes, stirring occasionally, until the onion becomes soft and translucent. This step develops sweetness and depth of flavor, which balances the tangy brightness of the salsa verde.

After the onion has softened, stir in 2 cloves of minced garlic. Cook for an additional 30 seconds, just until fragrant. Be careful not to let the garlic brown, as it can become bitter. This quick sauté enhances the savory base of the casserole and ensures that every bite carries a rich, layered flavor profile. Once done, remove the skillet from heat and set aside.

Build the Filling

In a large mixing bowl, combine 3 cups (about 450 g) of cooked, shredded or diced chicken with 1 ½ cups (360 ml) salsa verde and 1 cup (240 g) sour cream. Stir until the chicken is well coated. Add 1 teaspoon ground cumin, 1 teaspoon dried oregano, ½ teaspoon salt, and ½ teaspoon black pepper to season the mixture.

Next, fold in the sautéed onion and garlic. Mix thoroughly to distribute the aromatics and spices evenly throughout the filling. The sour cream creates a creamy texture that balances the zestiness of the salsa verde, while the cumin and oregano add warmth and depth. At this stage, the mixture should appear creamy and well combined, with no dry pockets of chicken.

Assemble the Casserole

Spread 2 cups (about 400 g) of cooked white or brown rice evenly across the bottom of the prepared baking dish. Press it gently into an even layer using the back of a spoon. This rice layer forms the hearty base of the casserole, soaking up the flavorful sauce as it bakes.

Carefully spoon the chicken mixture over the rice. Use a spatula to smooth it into an even layer, ensuring the filling reaches all corners of the dish. Even layering helps the casserole bake uniformly and ensures each serving contains a balanced combination of rice, chicken, and sauce.

Add the Cheese

Sprinkle 1 ½ cups (170 g) shredded mozzarella cheese and 1 cup (110 g) shredded cheddar cheese evenly over the top of the casserole. Distribute the cheese from edge to edge so every portion gets a generous, melty topping. The mozzarella provides stretch and creaminess, while the cheddar adds a sharper, richer flavor.

If desired, scatter ¼ cup (15 g) chopped fresh cilantro lightly over the cheese. This optional garnish adds a fresh pop of color and enhances the bright notes of the salsa verde.

Bake

Place the assembled casserole into the preheated oven and bake for 30–35 minutes. During this time, the filling will heat through, the flavors will meld together, and the cheese will melt into a bubbly, golden layer. Keep an eye on the top during the final minutes of baking; you’re looking for lightly golden edges and a gently bubbling center.

If you prefer a slightly more golden top, you can broil the casserole for 1–2 minutes at the end, watching closely to prevent burning.

Rest and Serve

Once baked, remove the casserole from the oven and allow it to rest for 5–10 minutes before serving. This resting period helps the layers set, making it easier to cut and serve neat portions. It also allows the flavors to settle and intensify slightly.

Serve warm, scooping down through all the layers to capture the rice, creamy chicken filling, and melted cheese in each bite.

Serving Suggestions

This casserole is satisfying on its own, but pairing it with the right sides can elevate the meal. A crisp green salad with a citrusy dressing offers a refreshing contrast to the creamy casserole. Warm flatbread or soft tortillas on the side can help scoop up every bite. For a lighter option, consider steamed vegetables or a simple tomato and cucumber salad.

Make-Ahead and Storage Tips

One of the greatest strengths of this recipe is how well it works for planning ahead. You can assemble the casserole up to 24 hours in advance, cover it tightly, and refrigerate until ready to bake. When baking from chilled, add an extra 5–10 minutes to the cooking time.

Leftovers store well in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the oven or microwave until warmed through. The flavors often deepen after a day, making leftovers especially delicious.

Frequently Asked Questions

1. Can I make this casserole ahead of time without baking it right away?

Absolutely. This casserole is an excellent make-ahead option, which is one of the reasons it’s so popular for busy schedules. You can fully assemble the dish, including the cheese topping, then cover it tightly with foil or a lid and refrigerate it for up to 24 hours. This allows the flavors to meld together even before baking. When you’re ready to cook, simply place it in the oven. Because it will be cold from the refrigerator, you should expect to add about 5 to 10 minutes to the baking time to ensure it heats through evenly. This approach is perfect for prepping dinner in the morning or the night before.

2. What type of chicken works best for this recipe?

This recipe is very forgiving when it comes to the type of chicken you use. Shredded chicken breast is a common choice because it stays tender and absorbs the salsa verde well. However, diced chicken thighs also work beautifully and can add a bit more richness to the dish. Rotisserie-style cooked chicken is another convenient option, saving you time without sacrificing flavor. The key is to ensure the chicken is fully cooked before adding it to the casserole, as the baking time is designed to heat and meld flavors rather than cook raw meat.

3. Can I adjust the level of spice in the casserole?

Yes, the spice level is easy to customize. Salsa verde can range from mild to quite bold depending on the brand or homemade version you choose. If you prefer a milder casserole, select a mild salsa verde and consider reducing the amount slightly, replacing a few tablespoons with extra sour cream. For those who enjoy more heat, opt for a spicier salsa verde or add finely chopped green chiles to the chicken mixture. This flexibility makes the recipe suitable for a wide range of taste preferences.

4. Is this casserole suitable for freezing?

Yes, this casserole freezes well, making it a great option for batch cooking. To freeze, assemble the casserole in a freezer-safe dish but do not bake it. Cover it tightly with plastic wrap and then foil to prevent freezer burn. It can be frozen for up to 2 months. When ready to bake, thaw it overnight in the refrigerator and then bake as directed, adding extra time if needed. Freezing may slightly change the texture of the rice and cheese, but the overall flavor remains comforting and satisfying.
