I love breakfast, and breakfast casseroles are such a nice change from the usual pancakes or bacon and eggs. This Eggless Breakfast Casserole with Sausage is meaty, cheesy, and potato-y, but not eggy! In fact, there are no eggs in this breakfast casserole. Sure, you could serve a side of scrambled or fried eggs, but if you’re going eggless, this meaty dish is truly satisfying!

Ingredients

  • Yellow Onion

  • Milk – Almond or soy milk can be a great dairy-free substitute.
  • Flour
  • Butter: You can use salted or unsalted butter.
  • Cheddar Cheese: Brings a sharp and tangy flavor. Feel free to mix in other cheeses like mozzarella or pepper jack.
  • Sausage: The star protein. Choose from a variety of sausages based on your preference. I like using bulk breakfast sausage for this breakfast casserole recipe.
  • Corn Flakes: Crushed lightly, they add a delightful crunch to the top layer.

How to Make This Eggless Breakfast Casserole Recipe

  1. Brown the sausage and onions in a skillet until they’re golden and aromatic.
  2. Remove excess fat from the skillet. Turn off the heat, then melt half the butter in the skillet with the sausage and add flour.
  3. Whisk in milk and turn the heat back to medium, stirring constantly until the sauce simmers and thickens.
  4. Add the bell pepper and let it simmer for 1-2 minutes.
  5. Season with salt and pepper to taste.
  6. Layer the thawed shredded potatoes at the bottom of a buttered 8×8 inch baking dish. Don’t forget to sprinkle some salt and pepper over the top to season them.
  7. Spread the sausage mixture evenly over the potatoes, ensuring every inch is covered.
  8. Sprinkle a generous amount of cheddar over the top.
  9. Melt the remaining butter in a microwave-safe dish and then toss the butter with the cornflakes. Sprinkle the buttered cornflakes over the top of the casserole.
  10. Bake covered at 375°F for 30-40 minutes. Then, uncover and bake for an additional 10 minutes until the top is golden brown.
  11. Serve and enjoy!

Chef Jenn’s Tips

  • If you’re not a fan of sausage, you can substitute it with diced ham or even tofu for a vegetarian version.
  • For a spicier kick, add some diced jalapeños or a dash of chili flakes to the sausage mixture.
  • Always let the casserole sit for a few minutes after baking. This allows the flavors to meld together, and it won’t be so messy getting it out of the baking dish.

Make it a Meal

This casserole is a meal in itself, but if you’re looking to make it even more special, consider serving it with a side of pancakes or quiche. Or, stick with something more simple like candied bacon, or a simple fruit salad.

Storage

Store any leftovers in an airtight container in the fridge for 3-4 days. You can reheat this breakfast casserole in the microwave or in a low oven. It is best eaten fresh; it will not freeze well.

    Why have I never thought to add corn flakes to a breakfast casserole? Seems like the perfect combo! I have one kid who won’t eat eggs and it really limits breakfast casseroles. Thank you for this eggless recipe!

    I love breakfast foods and would happily eat them most meals of the day! We made this with eggless casserole with spicy chicken sausage, and it turned out great. But, because I’m a big egg lover, I served it with a side of scrambled eggs. so much for eggless. LOL!

      At first, I thought eggless approach would be a mistake. But now, after tasting the epically cheesy goodness with sausage and potatoes, I’m sold! This is the way to go. Plus, the crunchy topping is so fun!

    Tried this casserole because of the title. No eggs. And that’s what I didn’t have at the time. I ran out of eggs but I had most of the ingredients except bell pepper. I went ahead making it without the pepper. No regrets. Me and the boys loved the casserole and had it as our brunch.

    I loved this casserole and used chicken sausages. I add some diced jalapeno as per your suggestion and it give the right kick to the cheesy casserole. My family loved it for a hearty brunch.

    This was a comforting breakfast! We loved it. Easy to make and very tasty. The crunchy topping was a hit with the kids and I loved that this can be made without eggs for those days when you have guests that don’t eat eggs.

    I made this yesterday morning for a brunch with friends.
    Most people coming ate eggs but two friends couldn’t so I wanted a casserole that everyone could eat.
    This was so delicious!
    I served it with some egg bites, some maple bacon, and some sauteed spinach.

    Oh and some mimosas because it was brunch with friends and why not 😉

    Thank you for a great recipe
