Notes

• Choose firm, fresh broccoli florets that are bright green and crisp for the best texture and flavor in your casserole.
• Shred the cheddar cheese yourself instead of using pre-shredded cheese, as it melts more smoothly and creates a creamier sauce.
• Make this dish gluten-free by substituting all-purpose flour with a gluten-free blend and using gluten-free biscuits or baking mix.
• For a vegetarian version, replace chicken broth with vegetable broth and swap shredded chicken for white beans or roasted cauliflower to maintain protein content.
