This hearty cheesy Trader Joes Breakfast Casserole Recipe is made with shredded hashbrowns, chicken sausage, and unexpected cheddar and ready in 60 minutes. The sharp cheese melts perfectly into the seasoned eggs while the bottom layer gets wonderfully crispy. I love keeping this in my weekend rotation for easy feeding.
Why This Classic Works
I used to struggle with soggy breakfast casseroles that never quite set in the middle. The turning point was realizing the hashbrowns need a quick pre-bake before adding the liquid ingredients.
Using entirely Trader Joe’s products makes the shopping trip simple and guarantees reliable flavor. The unexpected cheddar brings a sharp tang that cuts through the rich eggs.
Jump to RecipeTrader Joes Breakfast Casserole Recipe Ingredients
- 1 (20-ounce) bag Trader Joe’s Shredded Hashbrowns
- 1 (12-ounce) package Trader Joe’s Chicken Breakfast Sausage, chopped
- 10 large eggs
- 1/2 cup whole milk
- 1 cup Trader Joe’s Unexpected Cheddar Cheese, grated
- 2 cups fresh baby spinach, roughly chopped
- 1 tablespoon Trader Joe’s Everything But The Bagel Seasoning
- 1/2 teaspoon black pepper
- Cooking spray

How To Make Trader Joes Breakfast Casserole Recipe
- Preheat the oven: Preheat your oven to 375°F and lightly coat a 9×13-inch baking dish with cooking spray.
- Crisp the base: Spread the shredded hashbrowns evenly across the bottom of the dish and bake for 15 minutes.
- Whisk the eggs: In a large bowl, whisk the eggs, milk, Everything But The Bagel seasoning, and black pepper until fully combined.
- Layer the fillings: Remove the dish from the oven and scatter the chopped chicken sausage, spinach, and grated cheese over the hot hashbrowns.
- Pour and bake: Pour the egg mixture evenly over the top and return to the oven for 35 to 40 minutes until the center is set.
- Rest and serve: Let the casserole cool for 5 minutes before slicing to ensure it holds its shape perfectly.

Recipe Tips
- Thaw the hashbrowns: Letting the potatoes thaw slightly helps them spread easier and prevents excess water in the dish.
- Grate your own cheese: Pre-shredded cheese has anti-caking agents, so grating the Unexpected Cheddar from the block melts much smoother.
- Check the center: Give the pan a gentle shake to test doneness; the middle should jiggle slightly but not ripple like liquid.
What To Serve With Breakfast Casserole
Serve this hearty dish with a simple side of fresh fruit or mixed berries to balance the richness. A hot cup of dark roast coffee or a glass of fresh orange juice completes the morning spread.

How To Store
Store leftover casserole in an airtight container in the fridge for up to 4 days. You can also freeze individual portions wrapped tightly in foil for up to 2 months. Reheat in the microwave or a warm oven until heated through.
FAQs
- Can I prepare this the night before? Yes, you can assemble all the ingredients in the baking dish, cover tightly, and store in the fridge overnight. Add 5 to 10 extra minutes to the baking time if baking straight from cold.
- Can I use soy chorizo instead of chicken sausage? Absolutely. Brown the soy chorizo in a skillet first to release the flavors before scattering it over the hashbrowns.
- Why is my casserole watery? This happens if vegetables like spinach release too much moisture. Make sure to pat your fresh spinach dry before adding it to the dish.
