How to Make Cool Ranch Potato Casserole Recipe
Step 1: Preheat and Prepare Your Pan
Begin by preheating your oven to 400ºF to ensure it’s perfectly hot and ready for baking. Lightly spray a 9×13-inch baking dish with cooking spray—this little step prevents sticking and makes cleanup a breeze, plus it helps the potatoes develop a beautiful golden crust.
Step 2: Mix the Creamy Base
In a large bowl, combine the cream of chicken soup, sour cream, diced tomatoes and green chiles (with their juices), taco seasoning, ranch dressing mix, and shredded cheddar cheese. Stir everything together until you have a rich, colorful, and flavorful mixture that’s the heart of the casserole.
Step 3: Add Hash Browns and Combine
Gently stir the frozen shredded hash browns into your creamy base, making sure each potato shred is well coated with the luscious mixture. This step is where the magic happens—each bite will be packed with that perfect blend of creaminess and spice.
Step 4: Bake to Perfection
Pour the entire mixture into your prepared pan, spreading it out evenly. Place it in the oven uncovered and bake for 45 to 60 minutes. The casserole should be bubbly and golden on top, with the edges starting to crisp up slightly—signaling it’s time to dig in!

FAQs
Can I use fresh potatoes instead of frozen hash browns?
You certainly can, but frozen shredded hash browns save so much time and give a consistent texture. If using fresh potatoes, shred and rinse well to remove excess starch and pat dry to avoid a soggy casserole.
Is the Cool Ranch Potato Casserole Recipe spicy?
The dish has a mild to moderate spice level from the taco seasoning and green chiles, but the ranch mix and sour cream help balance and cool the heat. You can adjust the seasoning to your taste by adding more or less taco seasoning.
Can I substitute the cream of chicken soup with a vegetarian option?
Absolutely! Using cream of mushroom or a homemade vegetable cream soup works well and keeps the dish delicious while accommodating dietary preferences.
How long does it take to bake this casserole?
The casserole needs about 45 to 60 minutes in the oven at 400ºF to become bubbly and golden, depending on your oven and how thick the mixture is spread.
Can I add other ingredients to this recipe?
Feel free! Ingredients like cooked crumbled bacon, diced jalapeños, or black olives can add exciting new layers of flavor. Just remember to keep the balance so the creamy texture remains intact.
