What Goes Into This Recipe – Ingredients

• 2 cups cooked chicken (shredded or diced, rotisserie works wonders)
• 1 cup long-grain white rice (uncooked)
• 1 can (10 oz) diced tomatoes with green chilies (like Rotel)
• 1 cup chicken broth
• 1 cup shredded cheddar cheese
• 1 cup shredded Monterey Jack cheese
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1 teaspoon ground cumin
• 1 teaspoon chili powder
• 1/2 teaspoon smoked paprika
• 1/2 cup corn kernels (fresh, frozen, or canned, drained)
• 1/4 cup chopped cilantro (optional, but highly recommended)
• Salt and pepper to taste
• 2 tablespoons olive oil or vegetable oil
• Optional toppings: sliced jalapeños, avocado slices, sour cream, lime wedges

How to Make It – Instructions

1. Preheat your oven to 375°F (190°C). While that’s heating, prepare yourself mentally for a flavor explosion.
2. Sauté onion and garlic: In a large oven-safe skillet, heat olive oil over medium heat.

   Toss in the chopped onion, cooking until translucent (about 3-4 minutes), then add garlic and cook for 30 seconds more.

3. Add spices: Sprinkle in cumin, chili powder, smoked paprika, salt, and pepper. Stir for about 1 minute to toast those spices and really unlock their magic.
4. Mix in rice and liquids: Stir the uncooked rice into the skillet, coating it evenly with your spicy onion mixture. Pour in the chicken broth and diced tomatoes with their juices.

   Give everything a good stir to combine.

5. Layer chicken and corn: Scatter the cooked chicken and corn evenly over the rice mixture. Resist the urge to stir it all together—this layering helps keep the casserole nice and fluffy.
6. Cover and bake: Cover the skillet tightly with foil or a lid. Bake in the preheated oven for 30 minutes.
7. Add cheese topping: Remove from oven, uncover, and sprinkle cheddar and Monterey Jack cheeses over the top.

   Pop it back in the oven for another 10 minutes, or until cheese is bubbly and golden.

8. Garnish & serve: Once out of the oven, sprinkle with fresh cilantro and your choice of optional toppings. Squeeze a bit of lime over everything if you want to get fancy.

Keeping It Fresh

This casserole keeps beautifully in the fridge for up to 4 days. Store any leftovers in an airtight container, and to reheat, just pop it in the microwave or oven until warmed through.

Pro tip: Add a splash of chicken broth when reheating to prevent dryness. Freezing is an option too, but textures might shift slightly, especially the rice. Make sure to cool it fully before freezing in portions for quick meals down the line.

Benefits of This Recipe

• One-pot convenience: Less clean-up means more time for Netflix, pets, or pretending to be productive.
• Balanced meal: Lean protein from chicken, carbs from rice, plus veggies and spices—nutritionally satisfying and filling.
• Flavor-packed: Bold southwestern spices make your taste buds do somersaults.
• Highly customizable: Easily swap out proteins, add beans for extra fiber, or turn it vegan by ditching chicken & cheese.
• Cost-effective: Uses pantry staples and leftover chicken, perfect for budget-conscious cooks.

Pitfalls to Watch Out For

• Rice texture: Undercooking or overcooking rice can ruin the whole dish.

  Stick to the timing, and if you prefer softer rice, add a bit more broth.

• Dry chicken: Using dry or overcooked chicken can compromise juiciness. Rotisserie chicken or freshly cooked breast is ideal.
• Over-spicing: It’s easy to overdo chili powder or cumin if you’re not used to them. Start with recommended amounts; you can always add more next time.
• Cheese meltdown: Don’t leave the cheese on too long or at too high heat—nothing kills a vibe like burnt cheese crust.

Alternatives

• Swap chicken for turkey or beef: Ground versions work well, just brown the meat before mixing.
• Use brown rice or quinoa: Adjust cooking time and broth accordingly—brown rice takes longer and more liquid.
• Add black beans or pinto beans: For a vegetarian boost or added protein and fiber.
• Cheese varieties: Pepper Jack adds more kick; mozzarella offers a gooey stretch.
• Spice it up: Add chipotle peppers in adobo sauce or fresh jalapeños for an extra heat punch.

FAQ

Can I make this recipe in advance?

Absolutely!

You can prep the entire casserole and refrigerate it for up to 24 hours before baking. Just keep it covered tightly so it doesn’t dry out.

Is this recipe freezer-friendly?

Yes, but keep in mind the texture of rice and cheese may change slightly after thawing. Freeze in airtight containers and thaw overnight in the fridge before reheating.

What can I use if I don’t have a skillet?

Use any oven-safe baking dish you have, like a glass or ceramic casserole dish.

Just sauté the onions and garlic separately on the stove before adding everything into the dish.

Can I make this recipe spicy or mild?

Totally up to you. For milder, reduce or omit chili powder and use mild diced tomatoes without chilies. Crank up the spice with extra chili powder, jalapeños, or hot sauce.

What sides go well with this casserole?

Simple salads, guacamole, or a side of refried beans pair perfectly.

Some crispy tortilla chips for dunking never hurt either.
