This 5-ingredient oven chicken using frozen chicken breast chunks is my kind of weeknight lifesaver. You literally toss the frozen pieces straight onto a rimmed baking sheet, coat them in a quick, creamy mixture, and let the oven do the work. No thawing, no babysitting a skillet, and barely any dishes. It’s the kind of meal I lean on after a long day when I still want something that feels homemade and comforting, but I don’t have the brain space for a complicated recipe. The creamy, seasoned coating bakes up into a rich, flavorful crust that makes the chicken super juicy—my family always goes back for seconds.
Serve this creamy baked chicken with something that can cook or come together while the chicken is in the oven. I like pairing it with roasted veggies on a second sheet pan (broccoli, green beans, or carrots), or a simple side salad and warm rolls. It’s also great over buttered egg noodles, rice, or mashed potatoes to soak up the extra creamy sauce that collects on the pan. If you want to stretch it further, slice the cooked chicken chunks and tuck them into warm pitas or wraps with lettuce and cucumbers for an easy next-day lunch.
5-Ingredient Creamy Sheet Pan Frozen Chicken ChunksServings: 4
Ingredients
1 1/2 pounds frozen chicken breast chunks (uncooked, plain, not breaded)
1 cup sour cream (or plain Greek yogurt)
1/4 cup mayonnaise
1/3 cup grated Parmesan cheese
1 tablespoon ranch seasoning mix (dry packet, or your favorite all-purpose seasoning blend)
Directions
Preheat your oven to 400°F (200°C). Line a rimmed metal baking sheet with parchment paper or lightly coat it with nonstick spray for easier cleanup.
Spread the frozen chicken breast chunks in an even layer on the prepared rimmed baking sheet. The pieces can touch, but try not to pile them on top of each other so they bake evenly.
In a medium bowl, stir together the sour cream, mayonnaise, grated Parmesan cheese, and ranch seasoning mix until you have a thick, creamy, well-blended coating.
Spoon the creamy mixture over the frozen chicken chunks on the baking sheet. Use a spatula or clean hands to toss and coat all of the chicken pieces right on the pan until every piece is covered in the thick, creamy mixture.
Spread the coated chicken chunks back into a single layer on the baking sheet, making sure the creamy coating is fairly even across the top. This helps them brown nicely and cook at the same rate.
Place the baking sheet on the center rack of the preheated oven. Bake for 25–35 minutes, stirring once halfway through, until the chicken is cooked through and the creamy coating is bubbling and lightly golden in spots. The exact time can vary based on the size of the chunks and your oven.
Check for doneness by cutting into the largest piece to make sure there is no pink in the center and the juices run clear, or use an instant-read thermometer inserted into the thickest chunk to ensure it reaches 165°F (74°C).
Once done, let the chicken rest on the baking sheet for 3–5 minutes so the coating thickens slightly. Serve the creamy chicken chunks hot, spooning any extra sauce from the pan over the top.
Variations & Tips
You can easily tweak this 5-ingredient base to fit your family’s tastes or what you have on hand. Swap the sour cream for plain Greek yogurt to add extra protein and a little tang, or use all mayonnaise for a richer, more indulgent coating. If you’re not a fan of ranch seasoning, try an Italian seasoning blend, garlic and herb seasoning, or a mix of paprika, garlic powder, onion powder, salt, and pepper instead. For a little kick, stir in 1–2 teaspoons of hot sauce or a pinch of red pepper flakes to the creamy mixture before tossing with the chicken. You can also sprinkle extra Parmesan or shredded mozzarella over the top during the last 5–10 minutes of baking for a cheesier crust. To make this more of a one-pan meal, scatter quick-cooking veggies like thinly sliced bell peppers, zucchini, or halved cherry tomatoes around the chicken before baking, keeping in mind that crowded pans may need a few extra minutes in the oven. For meal prep, the leftovers keep well in an airtight container in the refrigerator for up to 3–4 days; reheat gently in the oven or microwave until steaming hot. Food safety tips: Always start with frozen chicken breast chunks that are meant to be cooked from frozen (plain, not pre-cooked). Bake directly from frozen; do not leave the chicken at room temperature to thaw on the sheet pan. Use a food thermometer to confirm the internal temperature reaches 165°F (74°C) in the thickest piece. Refrigerate leftovers within 2 hours of cooking and reheat only once for best quality and safety.
