Cheesy Hashbrown Chicken Casserole Ingredients

This recipe strikes the perfect balance of creamy, cheesy, and crispy. You’ll likely have most of these on hand.

The Casserole Base:

· 1 (30-32 oz) bag frozen shredded hash browns (thawed for 30-60 minutes, or use refrigerated)
· 3 cups cooked chicken, shredded or cubed (from 1 rotisserie chicken or 1.5 lbs cooked breasts/thighs)
· 1 medium yellow onion, finely diced
· 1 tablespoon olive oil or butter

The Creamy Sauce:

· 1 (10.5 oz) can cream of chicken soup (or cream of mushroom/celery)
· 1 (10.5 oz) can cream of celery soup (or a second cream of chicken)
· 1 cup full-fat sour cream
· 1/2 cup (1 stick) unsalted butter, melted
· 1/2 cup chicken broth or milk
· 1 teaspoon garlic powder
· 1 teaspoon onion powder
· 1/2 teaspoon dried thyme or poultry seasoning
· 1/2 teaspoon freshly ground black pepper
· Salt to taste (caution: soup and broth are salty)

The Cheese & Topping:

· 2 cups shredded sharp cheddar cheese, divided
· 1 1/2 cups shredded Colby Jack or Monterey Jack cheese
· 2 cups crushed cornflakes, crushed Ritz crackers, or French fried onions (for topping)
· 3 tablespoons butter, melted (for mixing with topping)

Optional Add-Ins:

· 1 (12 oz) bag frozen mixed vegetables (peas, carrots, corn), thawed
· 1 cup steamed broccoli florets, chopped
· 1/2 cup cooked, crumbled bacon

Step-by-Step Instructions for Casserole Perfection

Step 1: Prep and Preheat
Preheat your oven to 350°F(175°C). Lightly grease a 9×13-inch baking dish with butter or non-stick spray. Take the frozen hash browns out of the freezer to begin thawing.

Step 2: Sauté the Aromatics
In a small skillet,heat the olive oil or butter over medium heat. Add the diced onion and cook for 5-7 minutes, until softened and translucent. This step is crucial for building a flavor base and removing the raw onion bite. Set aside to cool slightly.

Step 3: Create the Luxurious Cream Sauce
In a very large mixing bowl,combine the cream of chicken soup, cream of celery soup, sour cream, 1/2 cup melted butter, chicken broth, garlic powder, onion powder, thyme, and black pepper. Whisk until the mixture is completely smooth and uniform.

Step 4: Assemble the Casserole
To the creamy sauce mixture,add the thawed hash browns, cooked chicken, sautéed onions, and 1 1/2 cups of the shredded cheddar cheese and all of the Colby Jack cheese. If using any optional add-ins like frozen vegetables, add them now. Using a large spatula or your hands, mix everything together gently but thoroughly until every component is coated in the sauce.

Step 5: Layer and Top
Transfer the entire mixture to your prepared baking dish.Press it down into an even, compact layer. Sprinkle the remaining 1/2 cup of cheddar cheese evenly over the top.
In a small bowl,mix the crushed cornflakes (or crackers) with the 3 tablespoons of melted butter until the crumbs are evenly moistened. Sprinkle this buttery crunch mixture evenly over the cheese layer.

Step 6: Bake to Golden, Bubbly Bliss
Bake,uncovered, for 50-60 minutes. The casserole is done when the edges are bubbling vigorously, the topping is deep golden brown, and the center is hot. A thermometer inserted into the center should read at least 165°F.

Step 7: Rest and Serve
Remove the casserole from the oven and let it rest for 10-15 minutes before serving.This allows the sauce to thicken slightly, making it easier to cut and serve clean, beautiful squares.

Pro Tips & Flavor Variations for the Perfect Dish

· Thaw Your Hash Browns: For the best texture and even cooking, let the hash browns sit on the counter for 30-60 minutes, or spread them on a baking sheet. Using them completely frozen can lead to a watery casserole.
· Homemade “Cream of” Swap: To avoid canned soup, make a quick roux: melt 4 tbsp butter, whisk in 1/4 cup flour, cook 1 minute, then whisk in 1 1/4 cups chicken broth and 1/2 cup milk. Cook until thick. Season with salt, pepper, and a pinch of thyme. Use in place of both canned soups.
· Shred Your Own Cheese: For the best melt and flavor, buy blocks of cheese and shred them yourself. Pre-shredded cheese is coated in anti-caking agents that can make the sauce grainy.
· Crispy Topping Variations: Use crushed potato chips, French fried onions, panko breadcrumbs with Parmesan, or even a extra layer of shredded cheese for a cheesy crust.
· Flavor Boosts: Add a dash of hot sauce or Worcestershire sauce to the cream mixture. Stir in 1/2 cup of grated Parmesan cheese for a salty, umami kick.
· Lighten It Up: Use low-fat soups, reduced-fat sour cream, and reduced-fat cheese. The texture will be slightly less rich but still delicious.

Essential Kitchen Equipment for Easy Casserole Assembly

Having the right tools makes assembling this family-sized meal a breeze.

Your Casserole Toolkit

9×13-Inch Baking Dish: The cornerstone of casserole making. A glass or ceramic dish provides even heating and allows you to see the browning edges. A metal pan will work but may cause faster browning on the bottom and sides.

Large Mixing Bowl: This is non-negotiable. You need a bowl large enough to comfortably mix all the components—hash browns, chicken, sauce, and cheese—without spilling. A large stainless steel or glass bowl is perfect.

Box Grater: If you’re shredding your own cheese from a block (highly recommended for creaminess), a box grater is the fastest, most efficient tool. A food processor with a grating disk is even faster for large batches.

Skillet: A medium skillet is needed for sautéing the onion, a key step for building foundational flavor and preventing a raw onion taste in the finished dish.

Flexible Silicone Spatula: Perfect for folding the dense hash brown mixture without breaking your utensils and for scraping every last bit of sauce out of the mixing bowl.

Measuring Cups & Spoons: For accuracy, especially with the seasonings and liquids that create the sauce’s balance.

This simple collection of tools is perfect for mastering not just this recipe, but a whole repertoire of easy one-dish meals.

Serving, Storing, and Make-Ahead Guide

· Serving Suggestions: This casserole is a complete meal, but it pairs wonderfully with:
· A bright, fresh green salad with a vinaigrette to cut the richness.
· Steamed green beans or roasted asparagus.
· A side of tangy coleslaw or applesauce.
· Make-Ahead Instructions: This casserole is a meal-prepper’s dream.
· Full Make-Ahead: Assemble the entire casserole (including the topping), cover tightly with plastic wrap and foil, and refrigerate for up to 24 hours. Bake as directed, adding 10-15 minutes to the baking time since you’re starting from cold.
· Freezer Meal: Assemble the casserole (hold the dry topping like cornflakes). Wrap unbaked dish tightly in plastic and foil. Freeze for up to 3 months. Thaw overnight in the fridge before adding topping and baking as directed.
· Storage & Reheating: Store leftovers covered in the refrigerator for 3-4 days. Reheat individual portions in the microwave, or reheat the entire casserole, covered with foil, in a 325°F oven until warmed through (about 20-30 minutes).
