- Coarsely Cracked Black Pepper: Freshly cracked black pepper adds an essential signature peppery warmth.
Step-by-Step Cooking Walkthrough
1. Brown the Sausage & Veggies: In a skillet over medium heat, cook ground sausage, onion, and red bell pepper until meat is thoroughly browned. Drain off excess fat.
2. Assemble the Dish: Spread patted-dry hashbrowns across the bottom of a greased 9×13 dish. Layer the cooked sausage mixture and half of the shredded cheddar evenly over the top.

3. Whisk & Pour Custard: Whisk eggs, whole milk, cracked pepper, garlic powder, onion powder, salt, and paprika until frothy. Pour evenly over the casserole. Sprinkle the remaining cheddar on top.
4. Bake Until Puffed: Bake uncovered at 375°F for 45 to 50 minutes until the center is set and edges are golden brown. Let rest 10 minutes before slicing into neat squares.
3 Chef Secrets for Perfect Results
1. Pat Hashbrowns Completely Dry: Frozen hashbrowns hold residual moisture. Thaw and press firmly between paper towels so your casserole stays crisp rather than watery.
2. Let It Rest Before Slicing: Allow the casserole to sit for 10 minutes out of the oven. This allows the egg custard to set completely so squares cut cleanly.
3. Make Ahead Like a Pro: Assemble the casserole fully, cover tightly with foil, and refrigerate overnight (up to 12 hours). In the morning, bake straight from the fridge, adding 5 to 10 minutes to the total bake time.
