Breakfast Casserole with Italian Sausage (Video)
This low-carb Breakfast Casserole has Italian sausage, mushrooms, and cheese and this is a delicious breakfast for anyone who loves Italian Sausage!
Years ago (when I was in the middle of house renovations!) I created this tasty Breakfast Casserole with Italian Sausage. And at the time I was so proud that I had been frugal and made up a new breakfast casserole recipe out of a couple of Italian Sausages I found in the fridge. Now fast forward 9 years and a new house later, and I’m still making this delicious breakfast casserole with Italian Sausage!
Now I make a bigger version and use the whole package of Italian sausage links, and recently I noticed that the old photos weren’t really showing this recipe off to it’s full glory. So last week I made it again and took new photos, and I just ate the last bit warmed up for breakfast as I was updating this post!
And YUM! I’m so glad I had the slightly crazy idea of putting turkey Italian sausage into a breakfast casserole. This Breakfast Casserole with Italian Sausage has fewer eggs than many of my low-carb breakfast casseroles, letting the flavors of the Italian sausage and mushrooms really shine.
I use Jenni-O Turkey Italian Sausage, my favorite sausage for low-carb recipes with Italian sausage, and if you use that and use low-fat cheese this low-carb dish can also be South Beach Diet friendly. And if you’d like to make a version that’s Keto, just use pork Italian Sausage and full-fat cheese. This will be delicious either way you make it, and if you’re an Italian sausage fan like I am, it just might become one of those breakfasts you make over and over!

- 19.5 oz. uncooked turkey or pork Italian sausage
- 2 tsp. olive oil + 2 tsp. olive oil (more or less, depending on your pan)
- 1 lb. sliced mushrooms (pre-sliced mushrooms make it easy, but rinse them before you slice if you're not using those)
- 2 cups grated Mozzarella cheese
- 1/4 cup sliced green onions, plus more to sprinkle over the top (optional but good)
- 1 cup cottage cheese, rinsed and drained
- 10 eggs, beaten until whites and yolks are well combined
- 1 tsp. Spike seasoning (optional but recommended, can also use any other spice blend you like with eggs)
- 1/4 cup coarsely grated Parmesan cheese
- fresh ground black pepper to taste
- Preheat oven to 375F/190C. Spray a large casserole dish (about 9" x 13") with non-stick spray.
- Add 2 tsp. olive oil to a non-stick frying pan over medium-high heat, squeeze turkey Italian sausage out of casings, and cook until sausage is done and starting to brown, about 5 minutes. I used the sharp side of a metal turner to break the sausage apart as it cooked.
- When sausage is done, spread out in a layer in the casserole dish.
- Wash mushrooms if needed, spin or pat dry, and slice (or use pre-sliced mushrooms). Heat another 2 tsp oil in the same frying pan and cook mushrooms until all liquid is released and evaporated and they're starting to brown slightly.
- Layer mushrooms over the sausage in the casserole dish.
- Sprinkle 1 cup grated cheese and 1/4 cup sliced green onions over the sausage and mushrooms.
- While sausage and mushrooms cook, put cottage cheese into a fine strainer, put strainer in sink and rinse cottage cheese gently with cold water and let drain well.
- Break eggs into a medium sized bowl or large glass measuring cup, then beat with a fork until yolks and whites are well combined. Add Spike Seasoning (affiliate link), drained cottage cheese, and 1/4 cup parmesan cheese and stir together.
- Then pour the egg mixture over the ingredients in the casserole dish.
- Use a fork to gently stir so all ingredients are coated with egg and well-combined.
- Sprinkle the other cup of grated cheese over the top.
- Bake 30-35 minutes, or until the center is completely set and the top of the breakfast casserole is starting to lightly brown.
- Serve hot, garnished with more green onions if desired.
This is also good served with sour cream. Egg casseroles like this can be kept in the fridge for up to a week and reheated quickly in the microwave. Be careful not to microwave too long.
