Texture & Flavor Secrets

The magic lies in the contrast: crispy fish sticks on top, creamy cheesy hashbrowns beneath. The eggs bind everything together into a custardy layer, while the cheese and dill make each bite cozy and flavorful. It’s the perfect mix of crunch and comfort.

Cooking Tips & Tricks

• Thaw hashbrowns completely to prevent excess moisture.
• Add a little extra cheese on top before baking for a gooey crust.
• Use convection bake if you want the top extra crispy.
• Try sprinkling crushed crackers or breadcrumbs for texture.

What to Avoid

Avoid these common mistakes for the best results:

• Not thawing the hashbrowns: They’ll release too much water.
• Overbaking: Can dry out the eggs and make it rubbery.
• Skipping seasoning: Since ingredients are mild, seasoning is key.
• Using too much milk: It can make the casserole watery.
