    💭Pro tips for making this casserole

    1. Use shredded hashbrowns

    I highly recommend using the shredded style of hash browns in this casserole for the best texture.

    2. Double the recipe to feed a crowd

    If you need to feed more than 4-6 people, simply double the recipe and bake the casserole in a 9"x13" baking dish.

    3. Make it ahead of time

    This is an amazing make-ahead dish. Prepare it in the dish the night before, pop it into the refrigerator, and it'll be ready to go into the oven in the morning!

    4. Freeze it for an always-ready breakfast

    This casserole can also be frozen so that you always have a delicious breakfast on hand. Just defrost it in the refrigerator and then bake it as directed.

    5. Helpful tools

    Here are a few tools that will help you make this casserole:

    • 8"x8" baking dish (or 9"x13" dish if doubling the recipe)
    • Medium skillet
    • Large bowl
    • Spatula

    Ingredients & substitutions

    labeled ingredients on the countertop.
    • Pork sausage - There is no alternative for the pork sausage.
    • Diced red pepper - The red pepper can be omitted if desired.
    • Chopped spinach - The spinach can be omitted if desired.
    • Dried minced onion - The dried onion can be substituted with ⅓ cup of fresh, chopped onion.
    • Frozen hash browns - I highly recommend using the shredded style of hash browns.
    • Salt - The salt can be omitted if you are following a low salt diet.
    • Pepper - There is no alternative for the pepper.
    • Almond milk - The almond milk can be swapped with another plant milk, or dairy milk if you can tolerate dairy.
    • Dairy free shredded cheddar cheese - This is the brand tested in the recipe. Regular cheese can also be used if you can tolerate dairy.

    Measurements for each ingredient, along with instructions for making the casserole are in the recipe card below.

    Note about dairy

    The wonderful thing about this recipe is that it's customizable! If you can tolerate dairy and want to use it in this casserole, feel free to use dairy milk and cheese. If not, go for the dairy free products and you'll be all set!

    Mixing

    Start by spraying an 8"x8" baking dish with cooking spray and set aside. Heat a medium skillet on medium heat and add the sausage and red pepper (step 1 above). Break up the sausage while it cooks for 2-5 minutes or until it's no longer pink. Add the spinach and cook for 1 minute or until the leaves have softened (step 2). Remove from the heat and sprinkle on the dried minced onion (step 3). Set aside. In a large bowl, add the hash browns, eggs, salt, pepper, almond milk, and cheese (step 4). Mix until combined (step 5). Stir in the sausage mixture (step 6). Scrape the mixture into the baking dish, cover, and place it in the refrigerator.

    Baking & serving

    Remove the dish from the refrigerator 30 minutes before baking, and preheat the oven to 350F. Bake the casserole, uncovered, for 30-35 minutes or until the eggs are completely set. Stick a knife into the middle and make sure it comes out without any runny egg on it. Serve and enjoy immediately!

    Storing

    The casserole can be stored in the refrigerator for up to 2 days. To reheat, bake in the oven at 250F for 25 minutes.

    FAQ's

    Can I make and bake the casserole on the same day?

    Yes! Even though this is a great recipe to make ahead, you don't have to. If you have a last-minute hankering for casserole, you can prepare and bake the casserole right away!

    How long does gluten free sausage casserole last?

    Leftovers will last up to 2 days in the refrigerator, but longer in the freezer.

    Can I freeze sausage casserole?

    Yes - this is an excellent dish to freeze. It reheats really well. Just make sure you defrost it completely in the refrigerator first, then bake it as instructed.

      Have you ever tried this as a muffin? Three-year-olds like that presentation better than a slice on a plate (as I would prefer.)
