🥣 Step-by-Step: How to Make Hashbrown Casserole
Step 1: Prep & Preheat
Preheat oven to 350°F (175°C)
Grease a 9×13-inch baking dish — or line with parchment
Step 2: Sauté the Aromatics
In a large pot or saucepan, heat olive oil over medium heat
Add onion — cook 5–7 minutes until soft and golden
Stir in garlic — cook 30 seconds until fragrant
✅ Don’t skip browning — it builds flavor.
Step 3: Make the Cheese Sauce
Sprinkle in flour — stir 1 minute to cook off raw taste
Slowly pour in chicken stock, stirring constantly
Add milk — keep stirring until mixture begins to thicken (5–7 mins)
Reduce heat to low
Stir in sour cream and 8 oz cheddar cheese until melted
Add parsley, salt, and pepper
Taste and adjust seasoning
✅ Sauce should be creamy and coat the back of a spoon.
Step 4: Combine & Transfer
In a large bowl, mix thawed hash browns and cheese sauce until fully coated
Pour into the greased baking dish
Spread evenly — no dry spots
✅ Pro Tip: Gently press down to eliminate air pockets.
Step 5: Top & Bake
Sprinkle 1 cup shredded cheddar over the top
Bake 35–40 minutes, until:
Top is golden and bubbly
Edges are crispy and browned
Center is hot and set
✅ Optional: Broil 1–2 minutes at the end for extra browning (watch closely!).
Step 6: Rest & Serve
Let cool 5–10 minutes — helps it set
Scoop and serve warm — each bite should be creamy, cheesy, and slightly crispy
Pair with:
Scrambled eggs
Biscuits
Or just a spoon — it’s that good
Leftovers? Reheat in the oven or air fryer — never microwave (kills the texture).
