Common Mistakes to Avoid
Making the Sausage & Egg Keto Breakfast Casserole can be simple, but there are common mistakes that can affect the final dish. Here’s how to avoid them:

- Overcooking the sausage – Cooking sausage too long can make it dry. Aim for browned but not burnt pieces for optimal flavor and texture.
- Not whisking eggs thoroughly – If the eggs are not well combined, the casserole may have uneven texture. Whisk until fully blended for a smooth consistency.
- Ignoring ingredient temperatures – Using cold ingredients can affect cooking time. Let eggs and cream sit at room temperature before mixing for better results.
- Cutting too soon – Slicing into the casserole while it’s still hot can cause it to fall apart. Allow it to cool slightly before cutting for clean squares.
