Protein-Packed Low-Carb Breakfast Casserole with Sweet Potato and Kale (Crustless Quiche)

Quick Overview

Why You’ll Love This Crustless Quiche Casserole

Looking for a healthy, satisfying way to start your day or simplify your meal prep? This incredible Protein-Packed Breakfast Casserole (think crustless quiche!) is your answer. It’s naturally gluten-free, loaded with vegetables like kale and sweet potato, and features a savory, layered filling of seasoned ground meat and eggs.

Unlike traditional high-fat quiches, this low-carb breakfast bake is built for modern health goals. It’s perfect for busy weeknights, Sunday meal prep, or serving a crowd. The rich flavors of smoked paprika, savory sage, and a splash of balsamic vinegar elevate this from a simple egg bake to a true healthy breakfast casserole.

Note on carbs: While this recipe contains sweet potato, it remains significantly lower in carbs than a standard pastry-crust quiche. For an even lower-carb option, substitute the sweet potato with an equal amount of grated butternut squash or zucchini.
