Key Ingredients and Why They Matter

This low-carb casserole thrives on fresh, whole-food ingredients that contribute to its rich taste and nutritional profile:

Shredded cheddar cheese – Adds richness and depth while keeping carbs low.
Heavy cream and cream cheese – Create a luxurious, creamy base that binds the casserole together.
Carrots (optional) – For a touch of natural sweetness and color, but can be minimized for stricter keto plans.
Garlic powder, onion powder, and black pepper – Essential flavor enhancers.
Crushed pork rinds or bacon crumbles – Great alternatives to high-carb toppings like breadcrumbs.
