Pro Tips for the Best Cheddar Bay Biscuit Egg Casserole Texture and Flavor

• Use fresh biscuits – Day-old dough can become too dense
• Evenly distribute cheese and eggs – For consistent flavor in every bite
• Let it rest after baking – This helps it firm up and slice cleanly
• Avoid overbaking – Start checking at 30 minutes to keep it moist
• Add greens – A bit of spinach or kale adds nutrition without altering the flavor
