Ingredients

• 2 tbsp oil: I recommend using olive or canola oil for sautéing.
• 1 cup finely-chopped onion: Fresh onions give the best flavor. Yellow or white work beautifully here.
• 2 tsp kosher salt (divided): A must for enhancing flavor without overpowering dishes.
• 1 tbsp minced garlic: Fresh garlic is unbeatable for that aromatic base.
• 3 cups shredded rotisserie chicken: This shortcut not only saves time but adds incredible flavor.
• 3 tbsp chili powder: Opt for a good-quality blend for a better flavor profile.
• 2 cups cooked rice: Regular white rice works fine, but you can also use brown or cauliflower rice for a healthier twist.
• 1 (15 oz) can black beans, rinsed and drained: Canned beans save time and are a fantastic source of protein.
• 1 cup frozen corn: Sweet corn adds a lovely crunch; no need to thaw!
• 1 cup jarred salsa: Choose your favorite brand for a kick of flavor; homemade salsa is even better if you have it on hand.
• 1 cup sour cream (or Greek yogurt): Personally, I love using Greek yogurt for a tangy note.
• 3 cups shredded Mexican blend or cheddar cheese (divided): Buy a block and shred it yourself for the best melt.
• Optional toppings: Sliced avocado, cilantro, sliced green onion, jalapeños, extra salsa, sour cream.

Ingredient Notes: Always pick the freshest ingredients you can for maximum flavor. When it comes to cheese, I often turn to brands like Tillamook or Trader Joe’s for great quality.

Prep Notes: Keep your sour cream or Greek yogurt at room temperature for easy mixing!

Step-by-Step Instructions

1. Preheat your oven to 375°F. Lightly grease a 9×13-inch baking dish with cooking spray or oil. If you prefer, line it with parchment paper for easier cleanup.

2. Sauté the aromatics: Heat 2 tbsp oil in a Dutch oven or large skillet over medium heat. Add the chopped onion and season with 1/2 tsp kosher salt. Cook for about 5 to 7 minutes, stirring occasionally, until the onions are soft and golden. Then, stir in the minced garlic and cook for another minute until fragrant.

3. Combine the chicken and spices: Add the shredded rotisserie chicken and chili powder to the onion mixture. Stir everything together to coat the chicken evenly, letting it cook for 2 to 3 minutes to warm through and awaken the spices. Turn off the heat.

4. Mix in remaining ingredients: Stir in the cooked rice, rinsed black beans, frozen corn, salsa, remaining 1 1/2 tsp kosher salt, and 1 cup of shredded cheese. Mix until fully combined. If your skillet gets too full, you can easily transfer the mixture to a large bowl for easier mixing.

5. Prepare for baking: Spread the filling evenly in your prepared baking dish. Top with the remaining 2 cups of shredded cheese for that gooey, melted layer!

6. Bake: Place in the preheated oven and bake for 20 to 25 minutes until it’s hot, bubbly, and golden on top. You’ll know it’s ready when the cheese is melted and starting to brown slightly.

7. Serve: Let the casserole cool for a few minutes, then add any toppings you like—sliced avocado, fresh cilantro, jalapeños, or an extra dollop of sour cream. Serve warm and enjoy the love infused in each bite!

Chef’s Tips: Make sure not to overcrowd the filling in the baking dish. If it fills to the brim, you might end up with a messy oven!
