Easy Fish Stick Casserole Recipe

When I first started working on this I thought, hmmm.... how can I make this GOOD (I mean really good!) when it's such a simple recipe and seriously, I nailed it!

Crispy fish stick over a bed of the best hashbrown casserole you've ever had. It's tasty, easy and made with pantry ingredients.

I love it when something comes together so easily!

Ingredients

For the exact measurements, please refer to the printable recipe card at the bottom of this post. 

• Frozen shredded hash brown potatoes - you can use shredded or cubed. You can even use diced fresh potatoes.
• Cream of chicken soup - Cream of mushroom soup or even cheddar cheese soup can be used instead.
• mayonnaise you can substitute with sour cream if you prefer.
• lemon juice or lime juice and sweet pickle relish
• Dry ranch dressing - this is the stuff in the packet.
• shredded cheese - I used cheddar cheese in this recipe, but you vary the cheese. Try mozzarella, or swiss cheese, both would be delicious.
• frozen fish sticks - I used Gorton’s fish sticks. But you can switch this up and use breaded shrimp, crab cakes, or even chicken nuggets!
