Low carb breakfast casserole sausage is my go-to when mornings threaten to unravel. First, I’ll admit, I’m not exactly the queen of calm before coffee—so making a dish like this ahead of time saves my sanity. There’s something magical about waking up to a hearty, savory breakfast that checks the boxes for Keto Breakfast Casseroles and even those watching their carbs.
Also, this casserole is a total lifesaver for busy weekdays or lazy weekends. You just pop it in the oven, and it fills the house with the best smells (which, let’s be honest, is half the reason I bake anything). No fancy tricks—just real food, real flavor, real easy. If your mornings are a hot mess like mine, this low carb breakfast casserole sausage might just become your new favorite rescue plan.
My Kitchen Story
Honestly, I stumbled into the world of low carb breakfast casserole sausage by pure accident. One hectic Saturday, I realized I had a fridge full of eggs, a stubborn block of cheddar, and beef sausage begging to be used. So, in classic ‘me’ fashion, I tossed them all together and crossed my fingers. The result? A baked wonder that made my family think I’d planned a gourmet brunch. (Spoiler: I hadn’t.)
Then, after a few tweaks—like swapping out pork for beef sausage and adding colorful bell peppers for some pep—I realized this casserole was not just delicious but fit right in with my efforts for a Healthy Breakfast Casserole High Protein kind of morning. I love that it’s oven-baked, just like my favorite Cranberry Turkey Stuffing Balls Baked Recipes—no standing over a skillet, no mess on the stovetop (well, okay, a little mess, but nothing wild).
What Makes It Stand Out
Also, I’m a big fan of recipes you can prep ahead, and this one ticks that box. Bake it the night before, and you’ve got breakfast (or lunch, or dinner) sorted for days. Plus, it’s endlessly customizable—throw in whatever veggies you have lingering or try a different cheese for a twist. If you’re hunting for Low Carb Breakfast Casserole Recipes that don’t skimp on flavor, this one’s a winner. And if you like experimenting, you’ll probably love the hands-off style of my Baked Mediterranean Flatbread Pizza Recipe Easy And Delicious too. Finally, nothing beats the feeling of pulling a bubbly, golden casserole from the oven—except maybe sneaking a bite before anyone else gets to it.

Handy Kitchen Helpers
First, since this low carb breakfast casserole sausage recipe bakes in the oven, you’ll want a trusty 9 x 13-inch baking dish. I always keep one handy, along with a well-loved skillet for browning the sausage and softening the veggies. Then, you’ll need a whisk and a large mixing bowl—both make combining those eggs and cottage cheese a breeze.
If you’re a fan of meal prepping like I am, this dish is perfect for storing in the fridge and reheating throughout the week. However, you could swap the cheese for a dairy-free alternative if you’re looking for a heart healthy breakfast casserole . Also, for anyone watching cholesterol, try using egg whites for a low cholesterol breakfast casserole —the texture stays surprisingly fluffy!
For more tips on building high protein low carb breakfast casseroles that actually keep you full, I always check out nutrition resources here. Finally, don’t forget to spray your baking dish well, or use parchment if you want extra insurance against sticking. If you love easy, hands-off recipes, you might want to peek at my favorite Crockpot chicken recipe too. It’s another great option for busy mornings!
Step-by-step method for a Baked recipe
Step 1
First, preheat your oven to 375 degrees F and spray a 9 x 13-inch baking dish with cooking spray to prevent sticking. This ensures the casserole cooks evenly and is easy to remove.
Step 2
Then, heat a skillet over medium-high heat and add half of the olive oil along with the breakfast beef sausage. Cook for about 5 minutes, stirring frequently, until the sausage turns golden brown. Next, transfer the cooked sausage to the prepared baking dish.
Step 3
Also, return the skillet to the stove and add the remaining olive oil. Sauté the chopped onion, diced green and red bell peppers, 1/4 teaspoon salt, and 1/2 teaspoon ground black pepper for about 5 minutes until the vegetables are slightly browned. Spread the sautéed vegetables evenly over the sausage in the baking dish.
In a large mixing bowl, whisk together the eggs, cottage cheese, milk, 1/2 cup shredded cheddar cheese, and 1/4 teaspoon salt. Pour this mixture over the sausage and vegetables, then gently stir so the peppers rise to the top, adding nice color. Finally, sprinkle the remaining cheddar cheese on top and bake uncovered for 40 minutes. Let it cool for 20 minutes before slicing into 10 pieces.
Tips and tricks to make this Baked recipe shine
For a delicious low carb breakfast casserole sausage, using the oven for baking allows the flavors to meld beautifully while keeping the texture just right. Also, letting the casserole cool before slicing helps it set and makes serving easier. If you want to try different cooking methods, slow cooker options can be great too, like in the Easy Slow Cooker Chicken Burrito Bowl Recipe For A Healthy Weeknight Dinner or the Slow Cooker Marry Me Chicken Recipe Easy Dump And Go Crockpot Dinner. These recipes show how slow cooking can also lock in moisture and tenderness, perfect for busy mornings.
Remember, this low carb breakfast casserole sausage pairs well with other Keto Breakfast Casseroles and Healthy Breakfast Casserole High Protein options. You can customize the veggies or cheese to suit your taste while keeping it low in carbs and high in protein. This makes it not only tasty but also a great choice for those following a Low Cholesterol Breakfast Casserole or Heart Healthy Breakfast Casserole plan. Enjoy your homemade baked casserole warm or cold for an easy, satisfying start to your day.
What to serve with this Baked recipe
This low carb breakfast casserole sausage pairs wonderfully with fresh greens or a simple fruit salad to keep the meal light and refreshing. Also, consider serving it alongside our Pan Fried Chicken Piccata Meatballs With Lemon And Capers Recipe for a delightful protein boost. Next, a side of roasted vegetables complements the hearty flavors perfectly. Another great option is the One Pot Merry Me Chicken Pasta Creamy Dinner Recipe Easy And Delicious, which adds a comforting touch to your breakfast or brunch table.
How to store and reheat
Since this casserole is baked, it holds up well in the fridge for up to four days. First, let it cool completely before covering it tightly with foil or placing it in an airtight container. When you’re ready to enjoy leftovers, reheat it in the oven to maintain that perfect texture and flavor. Also, you can reheat individual portions in the microwave, but the oven method helps keep it from drying out. Finally, baked casseroles freeze nicely too, so consider making a double batch for busy mornings ahead.
