This French Onion Chicken Hashbrown Casserole brings together the familiar flavors of French onion dip with cheesy chicken and crispy hashbrowns for a meal that makes everyone around the table happy. It is satisfyingly rich and hearty yet requires little fuss in the kitchen. My family asks for this on chilly days when we are craving comfort food without a lot of extra dishes or complicated steps.
I first tried this recipe during a weekend at home when everyone wanted something warm and cozy. The golden topping and creamy inside made it an instant favorite and now it is my go-to for simple gatherings.
Ingredients
- Boneless skinless chicken breasts: These form the protein-rich base. Choose firm pink chicken with no odor for best results
- Olive oil: Helps to cook and brown the chicken. Look for extra virgin oil for the richest flavor
- Garlic powder and onion powder: Adds additional layers of savory depth. Select fresh-smelling powders for best taste
- Paprika: For gentle warmth and color. Use smoked or sweet paprika depending on your favorite flavor
- Salt and black pepper: The basics to bring balance to every bite. Use freshly ground pepper if you have it
- Hashbrowns: Provides the hearty base and crispy contrast. Thaw and drain well for the best texture
- French onion dip: Pick a sour cream-based dip from the dairy case for creamy tangy onion flavor
- Can of cream of chicken soup: This pulls it all together in a velvety sauce. Opt for low sodium if you prefer milder taste
- Cheddar cheese: For plenty of melty goodness. Shred your own cheese for smooth melt
- French fried onions: For crisp salty crunch on top. Look for golden brown fresh packages with no burnt bits

This ensures the chicken stays juicy and flavorful

- In a seven by thirteen inch baking dish add thawed and well-drained hashbrowns cream of chicken soup French onion dip the cooked chicken and about one cup of shredded cheddar cheese. Mix everything together until all ingredients are evenly combined and coated. This step evenly distributes all that rich creamy flavor
- Top Off and Bake:
- Sprinkle the remaining cheese over the mixture and then scatter French fried onions across the top. Place the dish on the bottom rack of your preheated 350 degree oven. Bake for thirty to forty minutes until the casserole is bubbling and the hashbrowns are fully cooked through. The bottom rack helps keep the onion topping from burning

I am partial to the French onion dip in this recipe since it transforms simple chicken into something decadent and unique. Every time we make this casserole my kids always sneak crunchy onion topping from the bowl before it even makes it to the table.
Storage Tips
Allow the casserole to fully cool at room temperature before covering and placing in the refrigerator. This keeps things from getting soggy. Store in airtight containers or tightly wrap the baking dish for up to four days. For longer storage freeze individual portions wrapped well and thaw overnight before reheating.
Ingredient Substitutions
You can use rotisserie chicken instead of cooking chicken from scratch which saves time and makes this even more weeknight friendly. Greek yogurt can stand in for French onion dip if you mix in some caramelized onions and dried onion soup mix. Monterey Jack or mozzarella cheese works well if you want to change up the flavor of the cheese.
Serving Suggestions
This casserole shines as a main dish on its own but a bright green salad or steamed green beans makes a perfect fresh side. For a cozy meal serve with crusty bread to scoop up every bit of creamy sauce. It is also a popular addition to potlucks since it stays warm for a long time and everyone loves the crunchy top.
