Ingredients You’ll Need

There’s something incredibly rewarding about turning simple ingredients into a rich, oven-baked dish that feels like a complete meal in every bite. One of the things I love about this recipe is that it uses simple pantry ingredients. You probably already have most of them in your kitchen.

Base Ingredients:

• 500 grams breakfast sausage
• 4 cups frozen tater tots
• 6 large eggs
• 1 cup milk
• 1 1/2 cups cheddar cheese, shredded
• 1/2 cup mozzarella cheese, shredded
• 1 teaspoon salt
• 1/2 teaspoon black pepper

Optional Add-ins:

• 1/2 cup bell peppers, diced
• 1/4 cup onion, chopped
• 1/4 cup mushrooms, sliced
• 1/2 teaspoon paprika
• 1/2 teaspoon chili flakes

Step-by-Step Instructions

Cook the Sausage

Begin by heating a skillet over medium heat and adding the sausage. Break it into small pieces as it cooks to ensure even browning. Cook until fully done and slightly crisp on the edges, which enhances flavor. Drain excess grease to avoid a heavy casserole. This step builds the savory base and ensures the final dish has depth and balanced richness without being overly oily.

Prepare the Egg Mixture

In a large bowl, whisk together eggs, milk, salt, and black pepper until smooth and fully combined. The mixture should be light and slightly airy, which helps create a soft, custard-like texture when baked. This step is crucial for binding the casserole together while ensuring a creamy consistency throughout.

Assemble the Casserole

Lightly grease a baking dish and layer the cooked sausage evenly across the base. Add optional vegetables if using, then spread the tater tots in a single layer. Pour the egg mixture evenly over the top, ensuring all ingredients are coated. Finish by sprinkling cheddar and mozzarella cheese generously. Proper layering ensures even cooking and a well-balanced bite in every portion.

Bake to Perfection

Place the casserole in a preheated oven at 180°C (350°F) and bake until the eggs are fully set and the top turns golden brown. This usually takes around 35 to 40 minutes. Avoid opening the oven frequently, as it may affect the texture. The goal is a firm yet tender center with a slightly crisp, cheesy top.

Rest and Serve

Remove the casserole from the oven and allow it to rest for 5 to 10 minutes before slicing. This helps the structure set properly, making it easier to cut clean portions. Serve warm for the best texture and flavor. The result is a hearty, satisfying breakfast that holds together beautifully.
