This 3-ingredient oven chicken is exactly what I reach for on those weeknights when I walk in the door at 5:45 and everyone is already asking what’s for dinner. You literally put raw thin-sliced chicken breasts straight into an enameled baking dish, add just two pantry ingredients, and let the oven do the rest. The result is tender, juicy chicken with a rich, savory sauce that tastes like you fussed, even though you didn’t. It’s very much a Midwest, busy-weeknight kind of recipe—comforting, simple, and husband-approved in my house.
Serve this chicken with something that can soak up the flavorful juices in the bottom of the pan—mashed potatoes, buttered egg noodles, or steamed rice are all perfect. I like to add a quick veggie on the side, like roasted green beans (toss them on a second sheet pan while the chicken bakes), a bagged salad mix, or microwave-steamed broccoli. If you’re packing leftovers for lunch, slice the chicken and spoon some of the sauce over reheated rice or quinoa, then add a handful of raw veggies for crunch.
3-Ingredient Oven Chicken (Thin-Sliced Breasts)Servings: 4
Ingredients
1 1/2 pounds raw thin-sliced boneless skinless chicken breasts
1 cup bottled creamy Caesar salad dressing
1/2 cup grated or finely shredded Parmesan cheese (from a bag or tub is fine)
Nonstick cooking spray or a little oil for the baking dish (optional, for easier cleanup)
Directions
Preheat your oven to 375°F (190°C). Lightly spray or rub your enameled baking dish with a little oil if you want easier cleanup.
Lay the raw thin-sliced chicken breasts in a single layer in the enameled baking dish. It’s okay if the edges overlap just a bit, but try not to stack them so they cook evenly.
Pour the creamy Caesar dressing evenly over the chicken, using the back of a spoon to spread it so every piece is well coated. The chicken should be mostly covered in a thin layer of dressing, with some pooling around the edges.
Sprinkle the grated Parmesan cheese evenly over the top of the sauced chicken. Try to cover as much surface area as you can so you get a nice cheesy, golden top.
Cover the baking dish tightly with foil. Bake covered for 15 minutes to keep the chicken juicy and help it cook through.
After 15 minutes, carefully remove the foil (watch for steam). Return the dish to the oven, uncovered, and bake for another 10–15 minutes, or until the chicken is cooked through and the top is lightly golden. Thin-sliced chicken cooks quickly, so start checking around the 10-minute mark.
To be sure it’s done, use an instant-read thermometer inserted into the thickest part of a piece of chicken; it should reach at least 165°F (74°C). The juices should run clear, not pink.
Once cooked, let the chicken rest in the baking dish for 5 minutes. This helps the juices settle. Spoon some of the creamy, cheesy sauce from the bottom of the pan over each piece when serving.
Serve warm, straight from the enameled baking dish, with your favorite sides. Store leftovers in an airtight container in the fridge for up to 3–4 days, reheating gently so the chicken stays tender.
Variations & Tips
You can easily tweak this base recipe to fit what you have on hand or your family’s tastes. For extra flavor, sprinkle 1 teaspoon of garlic powder, Italian seasoning, or black pepper over the chicken before adding the dressing. If you don’t have Caesar dressing, ranch or a creamy Italian dressing will also work, though the flavor will be slightly different. For a little texture, add 1/2 cup seasoned breadcrumbs mixed with an extra 2 tablespoons of Parmesan on top before baking uncovered. If your husband (or kids) love a bit of spice, add a pinch of red pepper flakes to the dressing. To make this a more complete one-dish meal, tuck some quick-cooking veggies like halved cherry tomatoes or thinly sliced bell peppers around the chicken before baking; just know they’ll soften quite a bit in the sauce. Food safety tips: Always start with fully thawed chicken—if it’s still frozen in the middle, it won’t cook evenly. Keep raw chicken and its juices away from ready-to-eat foods and wash your hands, cutting boards, and utensils with hot, soapy water after handling it. Use a food thermometer to confirm the chicken has reached 165°F (74°C) in the thickest part before serving. Refrigerate leftovers within 2 hours of baking, and reheat until steaming hot before eating.
