Why You'll Love This Recipe
Key Ingredients
The foundation is a blend of smoky breakfast sausage, farm‑fresh eggs, and a trio of cheeses (sharp cheddar, creamy mozzarella, and a pinch of Parmesan). Thick‑cut potatoes create a satisfying base, while a splash of milk keeps the custard silky. Feel free to substitute turkey sausage for a leaner version, or use dairy‑free cheese and almond milk for a gluten‑free, lactose‑free twist without losing richness.
Instructions
Cook the sausage
Heat olive oil in a large skillet over medium heat. Add the crumbled sausage, breaking it apart with a spatula. Cook 5‑7 minutes until browned and crispy. Drain excess fat onto a paper towel, then set the sausage aside to cool slightly.
Prepare the custard
In a large bowl whisk together eggs, milk, salt, and pepper until fully combined. The mixture should be smooth with a faint froth. This will bind the casserole and keep it moist.
Layer the base
Spread the parboiled potatoes evenly in a greased 9‑x‑13‑inch baking dish. Sprinkle the cooked sausage over the potatoes, then distribute the shredded cheddar and mozzarella on top.
Add the custard
Pour the egg‑milk mixture evenly over the layered ingredients. Gently tap the dish on the counter to settle the custard and release any air bubbles.
Bake to perfection
Preheat oven to 375°F (190°C). Bake the casserole for 30‑35 minutes, or until the center is set and the top is a deep golden brown. Let rest 10 minutes before slicing.
Expert Tips
Tip #1: Use Day‑Old Potatoes
Cold, slightly dried potatoes hold their shape better during baking, preventing a mushy base.
Tip #2: Mix Cheeses
Combining sharp cheddar with mild mozzarella creates depth and a perfectly gooey melt.
Tip #3: Rest Before Cutting
A 10‑minute rest lets the custard set, making clean slices and keeping the interior moist.
Storage & Variations
Cool the casserole completely, then refrigerate in an airtight container for up to 3 days. Reheat 20 minutes at 350°F, covered with foil. For a vegetarian spin, replace sausage with sautéed mushrooms and spinach, and use a dairy‑free cheese blend.
