8 large eggs Large, room‑temperature.

1 ½ cups whole‑milk milk Replace with 2% for fewer calories.

2 cups shredded sharp cheddar cheese Mix half mozzarella for stretch.

1 cup frozen hash‑brown potatoes Thaw and pat dry for crispness.

½ cup panko breadcrumbs Toss with melted butter before sprinkling.

2 tbsp fresh thyme leaves Or 1 tsp dried thyme.

½ tsp kosher salt Adjust to taste.

¼ tsp freshly ground black pepper Adds subtle heat.

Instructions

Cook the sausage

In a large skillet over medium heat, crumble the sausage and cook until browned and fully cooked, about 6‑8 minutes. Drain excess fat, then set the meat aside to cool slightly.

Pro Tip: For extra flavor, add a pinch of smoked paprika while browning.

Prepare the custard

Whisk eggs, milk, salt, and pepper in a bowl until fully combined. Stir in half of the shredded cheddar and the fresh thyme; this mixture will set the casserole’s creamy interior.

Pro Tip: Warm the milk slightly (30 °C) to prevent the eggs from scrambling.

Layer the base

Spread the thawed hash‑brown potatoes evenly in a greased 9‑x‑13‑inch baking dish. Sprinkle the cooked sausage over the potatoes, then drizzle the custard mixture across the top, ensuring even coverage.

Pro Tip: Use a spatula to smooth the custard for uniform baking.

Add cheese and topping

Scatter the remaining cheddar evenly over the surface. Toss panko breadcrumbs with melted butter, then sprinkle the mixture on top for a crunchy, golden crust.

Pro Tip: For extra color, add a pinch of smoked paprika to the breadcrumbs.

Bake to perfection

Place the dish in a pre‑heated 375 °F (190 °C) oven and bake for 35‑40 minutes, or until the center is set, the cheese is melted, and the topping is golden brown. Let stand 5 minutes before serving.

Pro Tip: If the top browns too quickly, cover loosely with foil halfway through.

Expert Tips

Tip #1: Make Ahead

Assemble the casserole the night before, cover, and refrigerate. Bake straight from the fridge, adding a few extra minutes to the bake time.

Tip #3: Cheese Blend

Combine cheddar with a touch of Gruyère or Monterey Jack for extra depth and meltiness.

Tip #4: Spice It Up

Add a dash of crushed red pepper flakes to the breadcrumb topping for a subtle holiday heat.
