Cheesy potatoes. Let’s talk about them. This incredible holiday casserole wasn’t part of my childhood, and honestly, I feel like I missed out on 20 years of cheesy, carby goodness. But don’t worry—I’m making up for lost time! My first introduction to cheesy potatoes was at a Friendsgiving years ago, and ever since, it’s been a holiday staple in our home.

I’ve added my own twist to this classic, and let me tell you, it has ALL the holiday vibes while being super easy to make. So, grab your favorite apron and let’s dig into the recipe that everyone will be asking for.

Why This Casserole is a Must-Have

Seriously, where has this casserole been all my life? I grew up with mashed potatoes (delicious in their own right), but why settle for just one type of potato when you can have two? Plus, hello, cheese! This holiday casserole is guaranteed to become part of your yearly tradition. Your guests will thank you—trust me.

My Tiny Tweak for Maximum Flavor

  1. I added more cheese—because it’s the holidays and calories don’t count! The original recipe calls for two cups of shredded cheddar mixed into the casserole. I kept that but added an extra cup of cheddar underneath the cornflake topping. The result? A crispy, cheesy layer that’s absolute perfection.

Bonus: Make It Spicy!

For those who love a little heat, add chopped jalapeños. I like to keep half of the casserole spicy by mixing in ½ cup of diced jalapeños on one side and topping it with sliced jalapeños for easy identification. If your whole crew loves spice, go all in with 1 cup of jalapeños. You can use fresh or pickled—your choice!

The Secret to Easy Prep

This recipe is a lifesaver during busy holiday seasons. With plenty of pre-made ingredients, you can mix everything in one bowl and pop it into the oven. You can even make it ahead of time! Assemble the casserole, refrigerate for up to three days, then add the topping and bake when ready.

Pro Tip: For the meltiest, creamiest casserole, shred your cheese yourself. Pre-shredded cheese is convenient but coated to prevent clumping, which can affect melting. If shredding isn’t your thing, Tillamook’s pre-shredded cheddar is a solid alternative.

Topping:

  • 8 tbsp unsalted butter, melted and cooled
  • 2 cups cornflakes, crushed
  • 1 cup cheddar, shredded

Optional:

  • ½ cup pickled or fresh jalapeños, diced (for half the casserole; use 1 cup for the whole casserole)
  • 9 slices of jalapeños for topping (double for full spicy version)

Instructions:

  1. In a large bowl, mix hash browns, Cream of Chicken Soup, sour cream, butter, onion, salt, and pepper with 2 cups of cheddar until well combined. Pour into a greased casserole dish and top with the remaining cheddar. Option: Mix in diced jalapeños.

Make-Ahead Tips

  • Refrigerate: Assemble the casserole (without the topping), cover, and refrigerate for up to three days. Add the topping just before baking.
  • Freeze: Assemble the filling in a freezer-safe container and freeze for up to six months. Thaw overnight in the fridge before adding the topping and baking. You may need to extend the baking time if the center is still cold.
