This Spicy Sausage and Caramelized Onion Breakfast Bake is the perfect low carb breakfast recipe for meal prepping. Spicy Italian sausage, sweet caramelized onions, earthy mushrooms, tomato paste, and garlic, mixed with eggs and cheese, then baked to perfection. Whether you're hosting a weekend brunch or looking for a special weekday breakfast, this dish is a crowd-pleaser that will leave everyone craving seconds.
This Keto Spicy Sausage and Caramelized Onion Breakfast Bake is one of the very first recipes I started making when I set out to live a low carb lifestyle. All of these years later, it is still a family favorite. It's the kind of dish I have to double if I want to have any leftovers.
But speaking of leftovers, this is one of those dishes that just gets better and better each day. Many people on a low carb diet quickly get tired of eating eggs. Sometimes it is all about mixing things up and not just eating boring fried eggs day in and day out. This low carb and gluten free breakfast bake is the perfect way to do exactly that. I love the way the cheese mixes in to the eggs, but also floats up to the top of the egg mixture to form a delicious crust. It's like eating a low carb quiche recipe, but without the crust. Mmmmmm!
I love to top this with a dollop of sour cream and a sprinkling of fresh chopped green onions. The cool and creamy sour cream pairs perfectly with the flavors of the spicy sausage and caramelized onions. If you are looking for an easy one pot keto recipe, then this is the dish for you. Hey, it's not just for breakfast either. In our home, we are big fans of brinner - breakfast for dinner.

OMG this recipe is a lifesaver. I’m not a fan of eggs and of been struggling to find things that are not replacement carb-based to eat for breakfast. I made this two days ago and I cut it in half just in case it sucked. Now I’m kicking myself I should’ve made two batches because I am obsessed and my entire family loves this. Confession: I did add 1 tablespoon of coconut flour And a couple tablespoons of cream just to make sure that it wasn’t overly eggy and I made them as muffins so they’re easy to grab and go.. These will always be in my refrigerator. Thank you!

I made this today. I didn't have any hot sauce so I used chipotle sauce instead. It was so good. I am not a lover of eggs but the cheese/egg ratio is tasty. I am going to check out some more of your recipes and your site. Thanks for the recipe! It is a keeper!

Hi Kyndra,
Thanks for this recipe. My husband loves this and it's his favorite breakfast! We have also enjoyed many of your delicious soup recipes, I especially like the Reuben soup! You do a great job creating low carb, grain free recipes that are so satisfying. Keep up the good work! I have already purchased one of your cookbooks and have my eye on another.
Thanks again!
