Introduction
This three-ingredient breakfast casserole is one of the easiest make-ahead breakfast recipes you can prepare. It is rich, filling, and perfect for feeding a family with minimal effort. Using just eggs, sausage, and cheese, this casserole comes together quickly and bakes into a warm, comforting breakfast dish.
Ingredients (Serves 4–6)
- 6 large eggs
- 250 g cooked breakfast sausage or chicken sausage
- 1½ cups shredded cheese (cheddar, mozzarella, or a mix)
Step-by-Step Instructions
Step 1: Preheat the oven
Preheat your oven to 180°C (350°F). Lightly grease a baking dish or casserole pan.
Step 2: Prepare the sausage
Cook the sausage in a skillet over medium heat until browned and fully cooked. Break it into small crumbles while cooking. Drain any excess oil if needed.
Step 3: Beat the eggs
Crack the eggs into a large bowl and whisk until smooth and fully combined.
Step 4: Assemble the casserole
Spread the cooked sausage evenly in the greased baking dish. Sprinkle the shredded cheese on top. Pour the beaten eggs evenly over everything.
Step 5: Bake
Place the casserole in the oven and bake for 25–30 minutes, or until the eggs are fully set and the top is lightly golden.
Step 6: Cool and serve
Allow the casserole to rest for 5 minutes before slicing. Serve warm.
Tips for Best Results
- Use freshly shredded cheese for better melting
