An easy low-carb breakfast casserole
When following a low-carb diet, it’s nice to have easy breakfast options on hand. This sausage breakfast casserole is a go-to for an easy Keto breakfast. Just make it over the weekend and you can easily reheat the leftovers for an easy breakfast!
Other keto friendly breakfast options
We have a lot of other easy keto breakfast recipes. Here’s a link to check out all of our keto breakfast ideas. Some of our favorites are:
Of course, you could always skip breakfast and try intermittent fasting. Intermittent fasting goes along very well with a keto diet. Here’s a full post about my intermittent fasting results.
What keto sausage do you use?
Most of the time, we make our own sausage at home. Our homemade country breakfast sausage is an easy keto sausage recipe that you can use in this casserole!
Here are some options for purchasing no sugar added Keto sausage:
- Pederson’s Uncured No Sugar Breakfast Sausage
- Jones Dairy Farm Sausage Roll
- Mulay’s Breakfast Sausage
- US Wellness Meats No Sugar Breakfast Sausage
What veggies did you sneak in this keto egg casserole?
Eating a keto/low carb diet is hard, and we’ve found it can feel pretty limiting in what vegetables you consume. Sometimes you really want the flavor of garlic and onions, you know?
The good news is, when you make a large dish like this keto breakfast casserole, per serving you are only getting a small amount of garlic and onion so it remains fairly low carb. We also added in some mushrooms, spinach and fresh sage to compliment the eggs and sausage.
Dairy free keto
Cheese is really amazing, but we like providing you with options. Not everyone can tolerate dairy or might be cutting out dairy for a Whole30 or other reasons. For this recipe, the cheese is totally optional. It will turn out great either way! We added some avocado on top when we left out the cheese for a little bit of extra flavor.
If you are looking for dairy-free keto recipes, we have a lot in our archives! Almost all of our Keto recipes are dairy-free and if they are not the dairy is an optional ingredient.
