    The last thing you want to do during the holidays is prep a huge breakfast. Instead, we make this easy breakfast casserole and serve it with fruit. It’s a quick and easy recipe that looks like I spent an hour in the kitchen cooking it up.

    Have extra time? Serve it up with our Dairy Free Pancakes or Challah French Toast!

    Recipe ingredients and notes

    • Olive Oil – We use this to brown the sausage and the onions.
    • Sausage Patties – We use sausage patties to cut down the prep of browning raw meat. You can also use links. Our go-to brand is Jone’s Dairy Farm. You could also use bacon or ham.
    • Frozen Onions – We love having frozen onions on hand for recipes like this.
    • Eggs – We have not tested this with egg alternatives.
    • Shredded Cheddar Cheese – We’re dairy free, and use follow your heart finely shredded cheddar cheese.
    • Whole Milk – We use full fat oatly to make this in a dairy free breakfast casserole.
    • Potatoes – When making this, we prefer freshly shredded potatoes, but you can also use 1 1/2 cups of shredded frozen potatoes.
    • Salt and Pepper – To taste or as directed.

    How to make a breakfast casserole

    Preheat the oven to 350 degrees F and then grease a 8×11 inch baking dish and set aside.

    In a skillet, heat the oil and brown the frozen sausage so you can easily dice it into bite-size pieces. Then brown the onions quickly to release their flavor.

    Beat the eggs with the milk, and then add in the sausage, onions, cheese, shredded potatoes, and salt and pepper. Mix until combined and then pour into the prepared baking dish.

    Cover the dish with tin foil and bake for 45 minutes, then remove the foil and top with more cheese. Bake for another 10 minutes or until the cheese is melted. We like to garnish it with green onions.

    • This is great for meal prep, and you could easily freeze the leftovers.
    • We’re dairy free, and it’s easy to adapt this recipe to our allergen needs.

    Storage and reheating tips

    • Refrigerate: Store any leftover breakfast casserole in an air-tight container in the refrigerator and enjoy it within 3-4 days.
    • Freeze: Let the casserole cool for 30 minutes prior to placing it in a container or foil for freezing. Freeze up to 3-4 months for best quality.
    • Reheat: Place the breakfast casserole into an oven-safe dish in a 375 degree F preheated oven for 30 minutes covered and enjoy once warm throughout. For a piece, only do about 10 minutes.

    How to serve

    We love serving with fresh fruit and quick dinner rolls.

    Frequently asked questions

    Can I add other meat to the breakfast casserole?

    Yes, we love using leftover ham or crispy bacon!

    Can I make this in advance?

    Yes, we make it up to 24 hours in advance and just cover the baking dish with plastic wrap and refrigerate until ready to bake. When we’re ready to bake we let the mixture cool at room temperature for 30 minutes to avoid putting a cold casserole dish into a hot oven.
