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!

How to Make This Eggless Breakfast Casserole Recipe
- Brown the sausage and onions in a skillet until they’re golden and aromatic.
- Remove excess fat from the skillet. Turn off the heat, then melt half the butter in the skillet with the sausage and add flour.
- Whisk in milk and turn the heat back to medium, stirring constantly until the sauce simmers and thickens.
- Add the bell pepper and let it simmer for 1-2 minutes.
- Season with salt and pepper to taste.
- 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.
- Spread the sausage mixture evenly over the potatoes, ensuring every inch is covered.
- Sprinkle a generous amount of cheddar over the top.
- 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.
- Bake covered at 375°F for 30-40 minutes. Then, uncover and bake for an additional 10 minutes until the top is golden brown.
- 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.

This casserole was perfect for an eggless breakfast! The best part was the crunchy cornflake topping. Such a great idea – thank you.
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!
Your eggless breakfast casserole with sausage is a breakfast game-changer! The fact that it’s eggless doesn’t compromise on flavor or texture โ the combination of sausage, veggies, and seasonings is deliciously satisfying. Your clear instructions and ingredient substitutions make this recipe incredibly versatile, and the final result was a hit with my family. Thanks for sharing this fantastic recipe that accommodates dietary preferences without sacrificing taste โ it’s a definite winner in my breakfast rotation!
We were tired of eating eggs for breakfast so this casserole was a perfect option. The combination of sausage and potatoes was incredible.
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!
You had me at meaty and cheesy! This is the perfect breakfast casserole, especially for when you’re feeding a crowd. Christmas morning menu, here we come!
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 donโt eat eggs.
This turned out amazing! I love to make breakfast casseroles for Sunday brunch, we loved the cornflakes!
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 ๐
Thank you for a great recipe
I’m so glad you and your guests enjoyed it! ~Jenn
This was a surprisingly fluffy and filling casserole without eggs. What a great low carb breakfast.
