Can I use frozen broccoli in this casserole?
Yes, you can use frozen broccoli for this recipe. Simply add it directly to the slow cooker. Keep in mind that frozen broccoli might result in a slightly different texture, as it can become softer during cooking. If you prefer your broccoli with more bite, consider adding it halfway through the cooking time.
How can I make this casserole dairy-free?
To make this casserole dairy-free, you can substitute the cheddar cheese with a dairy-free cheese alternative. Use a dairy-free sour cream or plain coconut yogurt in place of regular sour cream. Ensure that the cream of chicken soup is also dairy-free, or make a homemade version using non-dairy ingredients.
