Common Mistakes to Avoid
Avoiding mistakes can make your One Pot Keto Tuna Casserole even more delicious and satisfying. Here are some common pitfalls to steer clear of:

- Skipping the cheese: Not including enough cheese may result in a less creamy casserole. Be generous with your mozzarella and cottage cheese for the best flavor.
- Ignoring seasoning: A bland casserole is no fun! Make sure to season adequately, especially with garlic salt and optional red pepper flakes for a kick.
- Neglecting prep time: Rushing through chopping vegetables can lead to uneven cooking. Take your time with prep to ensure everything cooks evenly.
