Yesterday afternoon, after hauling recycling bins back from the curb and helping my daughter with her reading, I glanced at the clock and realized dinner was still a mystery. The fridge offered shredded chicken from a weekend roast, and my stash of Mexican-style cheese begged for action. Our weekend taco night had stirred cravings for spicy, saucy comfort, but I needed something faster and a bit cozier for a family night dominoes game.

⁠

I pulled out an instant rice box and started mixing in cream of chicken soup, sour cream, and a bold fajita seasoning packet. Frozen bell peppers and onions added color and crunch without extra slicing, while diced tomatoes with chilies brought a warm, zesty punch. Stirred together with chicken and broth, it smelled like the perfect midweek escape. I spread it into a 9×13 dish, topped with cheese, and slid it into the oven.

By the time the timer chimed, the house smelled like our favorite Mexican restaurant but fresher and homemade. The cheese was bubbling, the rice fully soaked in those rich tomato-broth aromas, and the chicken tender and savory.

We served it straight from the pan, scooping generous portions under soft light lamps and chasing it with lively conversation and laughter. It hit that sweet spot: easy enough for a busy night, bold enough to make everyone smile.

Yes. Pre-cook brown rice separately, then mix before baking. Add ¼ cup extra broth.

Yes, greek yogurt works well and adds extra protein.

3. Is this spicy?
Only mildly, thanks to tomatoes with chilies and fajita seasoning. Omit chilies or reduce seasoning for a milder taste.

4. Can I use fresh bell peppers and onions?
Absolutely! Sauté them first, then let cool before mixing.

5. Can I make this vegetarian?
Yes, omit chicken, swap broth for vegetable broth, and add beans or roasted veggies instead.

Tips & Tricks

Warm your chicken broth before mixing—it helps the rice soften evenly.

Let the casserole sit for 5 minutes after baking to set, making it easier to serve.

Add a squeeze of lime juice on top before serving to brighten flavors.

Stir in black beans, corn, or avocado chunks for extra texture.

For a crunch on top, sprinkle crushed tortilla chips or cornflakes in the last 5 minutes of baking.
