This French Onion Chicken Hashbrown Casserole is perfect for anyone craving the richness of French onion dip blended with tender bites of chicken and a hashbrown base. Baked with lots of cheese and finished with crispy fried onions, each spoonful is a comforting, savory delight. I reach for this recipe on chilly nights when I want something cozy and filling but do not want to spend hours at the stove.

I first made this dish after a friend brought something similar to our potluck and my family now begs for it every winter. The flavors develop beautifully, making it just as good on day two.

Ingredients

  • Boneless skinless chicken breasts: use fresh chicken for the best texture and more flavorful bites
  • Olive oil: helps brown the chicken and adds richness
  • Garlic powder: brings a mild heat and a savory backbone to the seasoning mix
  • Onion powder: deepens the onion flavor and keeps seasoning even throughout
  • Paprika: choose smoked or sweet depending on your preference for a subtle earthiness
  • Salt and black pepper: adjust to taste for perfect seasoning
  • Hashbrowns: thaw before using to prevent excess moisture classic shredded style works best
  • French onion dip: choose a sour cream-based version from the dairy section for authentic taste and creamy texture
  • Can of cream of chicken soup: look for low-sodium if you like more control over saltiness
  • Cheddar cheese: shredding your own ensures the best melt and creamy finish
  • French fried onions: add crunch and iconic French onion flavor choose fresh for maximum crisp

Step-by-Step Instructions

Prepare the Chicken:
Season chicken with paprika onion powder garlic powder salt and pepper. In a large skillet over medium-high heat, add olive oil then chicken. Cook for seven to nine minutes until chicken is golden on the outside and reaches an internal temperature of one hundred sixty-five degrees. Cut into bite-sized pieces if not already
Assemble the Casserole:
In a seven by thirteen inch casserole dish, toss together thawed hashbrowns, cooked chicken, cream of chicken soup, French onion dip, and half the cheese. Use a large spoon to mix everything until evenly distributed and creamy
Add Toppings:
Sprinkle the remaining cheddar cheese evenly over the casserole top. Scatter French fried onions across the surface to form a thick layer that will get crispy as the casserole bakes
Bake the Casserole:
Place on the bottom rack of a preheated three hundred fifty degree oven. Bake for thirty to forty minutes, checking that hashbrowns are tender and onion topping is deeply golden brown. Let cool for a few minutes before serving

The real star for me is the French onion dip. Its tang and savory flavor infuse every bite without making the casserole heavy. My kids always fight over who gets the corners with the most crispy onions—a ritual at our dinner table.

Storage Tips

Let the casserole cool to room temperature before covering. Store in an airtight container or wrap the baking dish tightly. Leftovers will keep in the fridge up to four days or freeze wrapped portions for two to three months. To reheat, use a low oven or microwave, adding extra fried onions if needed to restore crunch.

Ingredient Substitutions

Rotisserie chicken is a great shortcut if you are short on time. You can swap cheddar for Monterey Jack or mozzarella for a milder taste. Greek yogurt mixed with onion soup mix can stand in for the French onion dip if you cannot find the sour cream-based version. Hashbrowns can be replaced with diced cooked potatoes in a pinch.

Serving Suggestions

Serve it as a main dish with a crisp green salad or simply steamed green beans. For a more complete meal, add roasted carrots or a side of crusty bread to catch all the extra sauce. Leftovers make great wraps or sandwich fillings the next day.

Commonly Asked Questions

→ Can I use rotisserie chicken instead of fresh chicken breasts?

Yes, rotisserie chicken is a convenient substitute. Simply shred or chop it and mix with the other casserole ingredients before baking.

→ Why is sour cream-based French onion dip necessary?

Sour cream-based dips provide the right creamy texture and classic flavor. Avoid using chip aisle onion dips, as they won’t melt or mix properly.

→ Should hashbrowns be thawed before baking?

Thawing hashbrowns prevents excess water in the dish and ensures they bake evenly for the best texture and taste.

→ How do I ensure the crispy onion topping doesn't burn?

Baking on the oven's bottom rack helps protect the fried onions from overbrowning while the casserole cooks through.

→ How long can leftovers be safely stored?

Store cooled leftovers in an airtight container in the fridge for up to 3-4 days, or freeze for up to 3 months.

What You'll Need

→ Casserole Base

01 600 grams boneless skinless chicken breasts, cut into bite-sized pieces
02 2 tablespoons olive oil
03 450 grams thawed hashbrowns
04 300 grams French onion dip (sour cream based)
05 300 grams canned cream of chicken soup

→ Seasonings

06 1 teaspoon garlic powder
07 1 teaspoon onion powder
08 1 teaspoon paprika
09 1 teaspoon salt
10 0.5 teaspoon freshly ground black pepper

→ Cheese & Topping

11 200 grams cheddar cheese, freshly shredded and divided
12 100 grams crispy French fried onions

Step-by-Step Directions

Step 01

Preheat oven to 175°C. Heat olive oil in a large skillet over medium-high heat. Add chicken pieces and season with paprika, onion powder, garlic powder, salt, and black pepper. Cook until chicken is fully cooked through and reaches an internal temperature of 74°C, approximately 7–9 minutes.

Step 02

In a 18x33 cm (7x13 inch) casserole dish, combine thawed hashbrowns, cream of chicken soup, sour cream-based French onion dip, cooked chicken, and 120 grams of shredded cheddar cheese. Mix thoroughly until well incorporated.

Step 03

Sprinkle the remaining cheddar cheese evenly over the mixture, then top with crispy French fried onions.

Step 04

Place the dish on the bottom rack of the preheated oven. Bake for 30–40 minutes, until the casserole is hot and hashbrowns are cooked through and topping is golden and crisp.

Step 05

Remove from the oven and let rest for 5 minutes before serving warm.

Helpful Notes

  1. Always use a sour cream-based French onion dip from the dairy section for ideal results.
  2. Ensure hashbrowns are fully thawed and drained of excess moisture to prevent a soggy casserole.
  3. Shred your own cheese for optimal melting and texture; pre-shredded cheese may not melt as smoothly due to anti-caking agents.
  4. For the crispiest topping, bake on the oven's bottom rack and avoid over-browning.
