Instructions

1. 1

   Prepare the dish

   Heat the oven to 220°C (425°F). Put the butter in a 33 x 23 cm (13 x 9-inch) glass baking dish and warm it in the oven for 2 minutes, or until melted. Take the dish out and brush the butter over the bottom and sides.

2. 2

   Bake the base

   In a large bowl, mix the thawed hash browns with 8 ounces of cheese, 1 egg, 1 1/2 teaspoons of salt and 1/2 teaspoon of pepper. Press the mixture evenly into the prepared dish. Bake for 20 minutes, then remove the dish and lower the oven to 190°C (375°F).

3. 3

   Cook sausage vegetables

   Crumble the sausage into a large non-stick frying pan and cook over medium-high heat, stirring to break it up, until browned and no longer pink. Lift it out with a slotted spoon into a small bowl. Add the bell pepper and 1/2 cup of onion to the pan and cook, stirring occasionally, for 5 minutes or until beginning to soften and colour.

4. 4

   Whisk egg mixture

   In a large bowl, whisk the remaining 11 eggs with the half-and-half, remaining 1 1/2 teaspoons of salt, ground mustard and remaining 1/2 teaspoon of pepper until blended.

5. 5

   Fill and bake

   Spread the sausage and pepper mixture evenly over the hash brown base, then add 4 ounces of cheese and pour over the egg mixture. Bake for 20–25 minutes, until the eggs are just set and a knife inserted in the centre comes out mostly clean.

6. 6

   Finish with cheese

   Sprinkle the remaining 4 ounces of cheese over the bake and return it to the oven for 2–3 minutes, until melted. Scatter the green onions over the top.

What is a hash brown egg bake?

It’s a casserole-style breakfast dish built from familiar American breakfast ingredients: potatoes, eggs, sausage and cheese. This version uses a baked hash brown base to hold a savoury egg filling.

The method gives the potatoes a head start in the oven before the filling goes on. That helps the base set and gives the eggs time to cook without leaving the potatoes underdone.

Nutrition and macros by portion

The nutrition label shows one serving as written: 410 calories, 22g protein, 17g carbs, 31g fat.

The hash browns provide most of the carbohydrates, while the butter, cheese, sausage and half-and-half contribute much of the fat. Eggs, cheese and sausage supply protein. Pair a serving with fruit or vegetables for a fresh contrast.

Why bake the hash browns first?

Thawed potatoes: removing excess ice and moisture helps the base hold together rather than turn watery. Press them into an even layer so the edges and centre bake at a similar pace.

Early bake: the 20-minute first bake firms the potato layer before the wetter egg mixture is added. Remember to reduce the oven temperature afterward.

Build flavour in the pan

Sausage: browning it first develops savoury flavour and gives you a chance to remove it from the pan before cooking the vegetables. Use a slotted spoon so excess fat stays behind.

Pepper and onion: cooking them briefly softens them while keeping some texture. They’ll continue cooking once the casserole goes into the oven.

Getting the eggs just set

Even layers: distribute the sausage and vegetables across the potato base before pouring in the egg mixture. This helps avoid one section being mostly filling and another mostly egg.

Doneness: start checking at 20 minutes. The centre should be just set, and a knife inserted there should come out mostly clean; the extra cheese goes on only after this check.

Choosing and dividing the cheese

Co-Jack: this combination of cheeses brings a creamy, savoury finish to the potatoes and egg filling. Shred it evenly so it spreads well across the casserole.

Divided portions: some cheese goes into the hash brown base, another portion tops the filling, and the final portion melts over the bake at the end. Follow the amounts in the method to keep those layers balanced.

Serving the bake

Let the dish rest briefly after baking so the egg layer can settle and portions are easier to lift out. Serve it warm, with green onions scattered over the top.

A fresh side such as sliced fruit or a simple green salad provides a contrast to the rich, savoury casserole. Cut portions with a spatula, making sure each one includes some of the potato base.

Recipe notes & tips

• Thaw the hash browns before mixing them into the crust.
• Press the potato mixture into a level layer for more even baking.
• Use a slotted spoon to transfer the browned sausage and leave excess fat in the pan.
• Whisk the egg mixture until the yolks and half-and-half are evenly blended.
• Check the centre at the early end of the baking time, as ovens can vary.
• Add the final cheese only after checking that the eggs are just set.

Variations

• Milder sausage: use mild Italian sausage if you prefer less heat.
• Extra vegetables: add more chopped bell pepper, keeping the filling layer even.
• Different cheese: swap in a similar melting cheese for the Co-Jack.
• Herb finish: add chopped fresh herbs alongside the green onions.
• More colour: use a mix of red and green bell pepper in place of some of the red pepper.

Common mistakes to avoid

• Using frozen potatoes: thaw them first so excess ice does not make the base wet.
• Uneven crust: press the hash browns into a consistent layer so they bake evenly.
• Skipping the first bake: bake the potato base before adding the egg filling so it has time to set.
• Overcooking the eggs: begin checking at 20 minutes and remove the dish when the centre is just set.
• Adding all the cheese at once: reserve the specified final portion for the brief melt at the end.

How to store

Refrigerate leftovers in a covered container and eat within 3–4 days. Reheat individual portions in the microwave or warm them in a 175°C (350°F) oven until heated through.
