Keto Sausage and Cheddar Breakfast Casserole
Keto Sausage & Cheddar Breakfast Casserole — The ultimate make-ahead breakfast. Two pounds of browned breakfast sausage layered with sautéed bell peppers, caramelized onions, and wilted spinach, all sealed under a thick, custardy egg base made with heavy cream, cream cheese, and two and a half cups of sharp cheddar. Baked until puffed and golden, then cut into big, satisfying squares that you grab from the freezer and microwave in under 3 minutes. The secret to why this doesn't turn rubbery like frozen scrambled eggs is the cream cheese — it melts into rich pockets throughout the custard that keep every bite moist and tender even after reheating. At 475 calories, 32g protein, and only 4g net carbs per square, it's the lowest-carb recipe in the rotation while still feeling like a full diner breakfast. Makes 8 large squares. Wrap individually in plastic wrap then foil, freeze flat for up to three months. Assemble the night before and bake in the morning if you prefer it fresh.
