Common Mistakes to Avoid
When making a Sausage & Egg Keto Breakfast Casserole, a few common mistakes can affect the final dish. Here are some tips to help you avoid them:
-
Using wilted spinach: Fresh spinach enhances flavor and texture. Always choose crisp, vibrant spinach leaves for the best results.
-
Overcooking the sausage: Cooking sausage too long can dry it out. Brown it just until crumbled and cooked through to keep it juicy.
-
Skipping egg whisking: Failing to whisk eggs properly can lead to uneven texture. Mix until fully combined for a creamy consistency throughout.
-
Not greasing the dish: A well-greased baking dish prevents sticking. Lightly grease your dish to make serving easier.
-
Ignoring cooking times: Baking for too long will result in a dry casserole. Check for doneness at 20 minutes to ensure it remains moist and fluffy.
