This oven baked 3-ingredient chicken Romanoff is the kind of simple, cozy casserole that earns a permanent spot in the dinner rotation. It has that unmistakable vintage casserole charm—tender chicken, creamy sauce, and noodles baked together until hot and bubbly—while still fitting into a busy modern weeknight. Recipes like this became popular in mid-century home cooking because they were affordable, practical, and built around pantry and fridge staples, and that same ease is exactly why it still works so well today.
Serve this creamy casserole with something fresh and crisp to balance the richness, like a simple green salad, steamed green beans, or roasted broccoli. Warm dinner rolls are great for scooping up the extra sauce, and if you want to round it out for Sunday dinner, applesauce, buttered peas, or a light cucumber salad all pair nicely.
Oven Baked 3-Ingredient Chicken Romanoff
Servings: 6
Ingredients
3 cups cooked chicken, chopped or shredded
8 ounces egg noodles, cooked and drained
2 cups sour cream
Directions
1. Preheat the oven to 350°F and lightly grease a medium casserole dish.
2. In a large bowl, combine the cooked chicken, cooked egg noodles, and sour cream until everything is evenly coated.
3. Spread the mixture into the prepared casserole dish and smooth the top into an even layer.
4. Bake uncovered for 25 to 30 minutes, until the casserole is hot throughout and lightly golden and bubbly around the edges.
5. Let it rest for 5 minutes before serving so the sauce settles slightly, then spoon onto plates and serve warm.
Variations & Tips
Add a buttery topping: If you want a little more texture, scatter a handful of crushed butter crackers or breadcrumbs over the top before baking. It keeps the recipe simple but gives the casserole a golden, lightly crisp finish.
Use rotisserie chicken: This is one of the easiest ways to get dinner in the oven fast on a busy night. Just pull the meat from a plain rotisserie chicken and chop or shred it before mixing it with the noodles and sour cream.
Season it your way: Even though the base recipe sticks to three ingredients, a little black pepper, garlic powder, onion powder, or paprika can wake up the flavor without changing the spirit of the dish.
Don’t overbake: Since the chicken is already cooked, the goal is simply to heat the casserole through and let the top get lightly golden. Baking too long can make the sauce separate a bit and dry out the noodles.
Make-ahead tip: Assemble the casserole earlier in the day, cover, and refrigerate until you’re ready to bake. If it’s going into the oven cold from the fridge, add about 5 to 10 extra minutes to the baking time so the center gets hot.
