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.

I'm just wondering does it taste like egg or is it like crusty? I'm not a fan of egg taste. But this looks good

This was AMAZING! Been eating low carb for four months and stumbled across your recipe and blog. So yum!! I did make a couple substitutions. I don't like sausage or mushrooms so I used ground beef and tomatoes instead. Delish!

Thanks so much for creating such yummy, low carb recipes. I follow a Ketogenic diet, so your website is very helpful to me. I track my diet on SparkPeople.com so I added this recipe to their database and said I had adapted it from yours at peaceloveandlowcarb.com.

No sausage fans in this house. Any ideas on what I can use as a substitute?

This looks delicious with easily accessible ingredients! Might have to give this a try, but since I'm the only one in the house that would eat it (husband is very picky with food), I will probably scale down the recipe to a smaller ovenware size.

This one looks delicious but I would skip the "hot" sausage and the "hot" sauce . I do not like "hot" stuff. I will let you know. I'm pretty sure that it's going to be as delicious as the "hot" one. Thanks again for your recipes..........
