Tips for the Perfect Breakfast Casserole

1. Use Quality Ham

Leftover ham works great, but choose one with minimal added sugar for keto-friendly results.

2. Don’t Overbake

Overbaking can make the eggs rubbery. Remove when the center is just set.

3. Let It Rest Before Cutting

This helps the casserole firm up and makes slicing easier.

4. Drain Vegetables Well

If using frozen spinach, squeeze out excess moisture to prevent a watery casserole.
