When I need a dinner that feels comforting but asks almost nothing from me after a busy workday, this oven baked 4-ingredient smothered chicken tenderloins recipe is one of my favorite back-pocket meals. It has that classic creamy, savory casserole-style flavor that makes everyone think you worked a lot harder than you did, and using raw chicken tenderloins keeps prep especially fast since they cook quickly and stay tender in the oven.
This chicken is great served over mashed potatoes, white rice, buttered egg noodles, or even toast if you want to soak up every bit of the rich sauce. For something green on the side, steamed broccoli, green beans, or a simple salad balance the creamy smothered chicken really well, and if I am meal-prepping, I like to pack it with rice and roasted carrots for easy lunches.
Oven Baked 4-Ingredient Smothered Chicken Tenderloins
Servings: 4
Ingredients
1 1/2 pounds raw chicken tenderloins
1 packet dry onion soup mix, about 1 ounce
1 can condensed cream of chicken soup, 10.5 ounces
1 cup sour cream
Directions
1. Preheat the oven to 375°F and lightly grease a medium ceramic casserole dish if needed.
2. Arrange the raw chicken tenderloins in an even layer in the casserole dish.
3. In a medium bowl, stir together the dry onion soup mix, condensed cream of chicken soup, and sour cream until smooth and well combined.
4. Spread the mixture evenly over the chicken tenderloins so they are fully coated.
5. Bake uncovered for 35 to 40 minutes, or until the chicken is cooked through and reaches 165°F in the thickest part.
6. Let the dish rest for 5 minutes before serving, then spoon plenty of sauce over each portion.
Variations & Tips
Mushroom Version: Add 1 cup sliced mushrooms to the casserole dish before spreading on the sauce if you want a deeper, more savory flavor that feels a little extra cozy.
Extra Seasoned: If your family likes a little more flavor, add 1/2 teaspoon black pepper, 1/2 teaspoon garlic powder, or a light sprinkle of paprika to the sauce mixture.
Make It a Full Meal: Nestle quick-cooking vegetables like broccoli florets or sliced zucchini around the chicken during the last 15 minutes of baking for an easy all-in-one dinner.
Prep Ahead Tip: You can assemble the casserole a few hours ahead, cover it, and refrigerate it until dinnertime. If baking straight from the fridge, add a few extra minutes to the cooking time and check that the chicken reaches 165°F.
Storage Tip: Leftovers keep well in the refrigerator for up to 3 days. Reheat gently so the creamy sauce stays smooth, and add a small spoonful of milk if you want to loosen the sauce.
