A fluffy, cheesy egg casserole loaded with browned sausage, colourful peppers and green onions. Easy to make ahead and perfect for Easter brunch or any holiday morning.
Heat the oven to 350°F and coat a 9x13-inch pan with cooking spray.
In a large bowl, beat the eggs, sour cream, milk, cheese, salt and pepper on low speed with an electric mixer until just combined.
Brown the sausage in a large skillet over medium heat, breaking it into small crumbles with a wooden spoon. Drain off most of the grease and add the sausage to the egg mixture.
In the same skillet, cook the bell peppers and green onion for 2 to 3 minutes. Add them to the bowl and stir everything together.
Pour into the prepared pan and bake for 35 to 50 minutes, until the edges are set and the centre has just the slightest jiggle.
Notes
Make ahead: Prepare through step 4, cover and refrigerate (unbaked) overnight or up to 1 day, then bake as directed.
Freezing: Assemble in the pan, wrap well in plastic wrap and then foil, and freeze for 2 to 3 months. Thaw overnight in the fridge, let it come to room temperature, then bake.
Leftovers: Refrigerate and eat within 3 to 4 days. Reheat in the microwave.
Nutrition: Estimated per serving from the ingredients, with the sausage drained.
