Helpful Tips

Here are some pointers to help you get the best results with this casserole.

• Rinse quinoa thoroughly to remove its natural bitterness.
• Don’t overcook the broccoli; it should retain a bit of crunch for texture.
• Use sharp cheddar for a more pronounced cheese flavor.
• Let the casserole rest for 5-10 minutes after baking to set up for easier slicing.
• If you want it creamier, add a little extra yogurt or milk before baking.

Ingredient Swaps

Feel free to swap out ingredients based on what you have or dietary preferences.

• Replace broccoli with cauliflower or green beans.
• Use cheddar alternatives like gouda or Monterey Jack.
• Swap Greek yogurt for sour cream or a vegan yogurt.
• Use chicken broth instead of vegetable broth for a meatier flavor.
• Try almond milk or oat milk instead of dairy milk for a dairy-free option.

• Store leftovers in an airtight container in the fridge for up to 4 days.
