Ingredients for Recipe for Chicken Tenderloins in a Casserole

Pantry staples and fresh chicken come together for a satisfying one-dish dinner.

The chicken tenderloins are key here. Look for uniform pieces at your butcher or grocery store to ensure even cooking. Whole Foods or Costco often carry high-quality options. For the cheddar, sharp varieties from Sargento or Tillamook melt beautifully and add a rich depth of flavor. Avoid pre-shredded cheese—it often contains anti-caking agents that affect meltability.

No cream of chicken soup? Cream of mushroom works just as well. For a lighter option, Greek yogurt at half the quantity can substitute for sour cream. Fresh out of peas and carrots? Frozen broccoli or green beans (thawed and drained) are great alternatives. The rice can be swapped for quinoa or orzo, but adjust the liquid ratio accordingly.

This casserole keeps well in the fridge for up to 4 days and reheats beautifully. Portion leftovers into containers for easy lunches. For longer storage, freeze for up to 3 months—just thaw overnight before reheating.

Step-by-Step Instructions for Chicken Tenderloins in a Casserole

This streamlined method delivers a complete meal with minimal active preparation time.

Step 1: Sear and Season the Chicken Tenderloins

Heat 1 tbsp olive oil in a large skillet over medium-high heat until shimmering. Add the 1.5 lb chicken tenderloins and cook for 3-4 minutes per side until lightly golden. This initial sear locks in juices and prevents the chicken from drying out during baking.

Season the chicken with 1 tsp salt, 0.5 tsp black pepper, 0.5 tsp paprika, 1 tsp dried thyme, and 1 tsp dried rosemary. I crush the dried herbs between my fingers as I sprinkle them to release their essential oils for maximum flavor impact. Remove the chicken from the skillet and set aside.

Step 2: Sauté Aromatics and Prepare the Rice Base

In the same skillet, add the remaining 1 tbsp olive oil. Sauté the finely diced yellow onion for 3-4 minutes until translucent. Add the minced garlic cloves and cook for 30 seconds until fragrant—don’t let it brown or it will turn bitter.

Stir in the 1 cup long-grain white rice, coating it in the oil and aromatics. Pour in the 0.5 cup chicken broth and 1 can cream of chicken soup, stirring to combine. The mixture should be creamy and slightly thick. This forms the flavorful base that will cook into a creamy, risotto-like texture in the oven.

Step 3: Assemble the Casserole Layers

Spread the rice mixture evenly in a greased 9×13-inch baking dish. Arrange the seared chicken tenderloins on top. Distribute the 1 cup thawed frozen peas and carrots around the chicken pieces, pressing them lightly into the rice mixture.

In a small bowl, mix the 0.5 cup sour cream until smooth, then dollop it over the chicken and vegetables. This adds a tangy richness that balances the savory elements. Sprinkle 1 cup of the shredded cheddar cheese evenly over the top, reserving the remaining 0.5 cup for later.

Step 4: Bake to Perfection and Finish

Cover the baking dish tightly with foil and bake at 375°F for 25 minutes. This allows the rice to absorb the liquids and cook through without drying out. Remove the foil and sprinkle the remaining 0.5 cup shredded cheddar cheese on top.

Return the dish to the oven and bake uncovered for an additional 10-15 minutes until the chicken reaches an internal temperature of 165°F and the cheese is bubbly and golden brown. Let the casserole rest for 5 minutes before serving to allow the flavors to meld and the cheese to set slightly.

Pro Cooking Tips for This Dish

Even Searing

Pat the 1.5 lb chicken tenderloins completely dry before searing to prevent steaming. I use paper towels to remove every bit of moisture. This ensures a beautiful golden crust forms in 3-4 minutes per side in medium-high heat. 🔥

Rice Perfection

Toast the 1 cup long-grain white rice in the skillet with aromatics for 1-2 minutes before adding liquids. This enhances the nutty flavor and prevents mushiness. The rice will absorb the chicken broth and cream of chicken soup beautifully.

Aromatic Balance

Cook the diced yellow onion until translucent, not browned. Add the minced garlic only at the end, as burning it creates bitterness. I crush the dried thyme and rosemary between my fingers to release their oils.

Layering Technique

Press the peas and carrots lightly into the rice mixture so they cook evenly. Distribute the sour cream in dollops rather than stirring it in. This creates pockets of creamy richness throughout the casserole.

Cheese Strategy

Use 1 cup cheddar under the foil to melt into the dish, then add the remaining 0.5 cup at the end for a golden, bubbly finish. I prefer sharp cheddar for bold flavor. Let it rest 5 minutes before serving. ✨

Oven Control

Bake covered at 375°F for 25 minutes, then uncover to allow the top to brown. Check the chicken reaches 165°F internally. This two-phase baking ensures even cooking without drying out the tenderloins.
