The Ultimate Keto Breakfast Casserole Secret: The Meats Matter

This keto egg casserole isn’t just about having a high enough fat content and low enough carb count. While it’s important to get the numbers right to stay in ketosis, the quality of the ingredients going into your keto breakfast casserole also matters.

#1 Cook the Sausage & Bacon for your Keto Breakfast Casserole

This low carb sausage egg and cheese casserole is one of my all-time FAVORITE meal prep recipes. Not only is it one of the tastiest casseroles in my opinion, but it’s also one of the simplest to prepare! Plus, o just love the versatility of being able to enjoy it as a keto breakfast casserole OR keto dinner casserole whenever I please.

First, before assembling your keto egg casserole to bake, we have to cook the breakfast meats. I start by cooking my breakfast sausage in a pan, breaking it up with a spoon and cooking through until no longer pink. Then, remove the sausage and set aside.

Next, add your chopped bacon to the same pan, slightly undercooking it. Don’t worry, it’ll continue to cook while your keto breakfast casserole is in the oven. But be careful during this step—chopped bacon tends to release more of its fat, so the hot oil tends to pop a lot!

Carefully remove the bacon from the pan with a slotted spoon or scoop colander and set aside. But, leave some of that bacon fat in the pan—it’ll add loads of delicious umami flavor to your veggies! (There was A LOT of bacon grease in my pan, so I used a ladle to remove some of it and left just enough to cover the pan.)

#2 Sauté Veggies and Combine with Breakfast Meats

With some of that tasty, nutrient-packed bacon day in the pan, sauté chopped onion and sliced mushrooms for about a minute. Then, add chopped asparagus and continue to cook for another 5 minutes or so, until the veggies are tenser but the asparagus is still a bit crisp. You can use whichever veggies you prefer, but these are some great low carb vegetable choices!

Finally, grab your cooked breakfast sausage and bacon and add it back into the pan with your veggies. Give it a stir so everything is integrated, and your keto breakfast casserole is ready to assemble!

#3 Assemble Keto Egg Casserole to Cook

Once your breakfast meat and veggie mixture is cooked, add it into a 9×13-inch baking dish and spread into an even layer. You can use a dish of a similar size if that’s what you have, just make sure it’s oven-safe and still large enough to hold all of your keto egg casserole ingredients.

Now, all that’s missing is the eggs! In a large bowl or measuring cup, whisk together a dozen eggs with the milk of your choice, along with salt and pepper to season. Then, just pour that whisked egg mixture over the meat and veggies in your casserole dish.

Twelve eggs may seem like a lot, but remember you’ll be cutting this casserole into 8 pieces! As for the milk, any kind that suits your lifestyle will do. I went with almond milk to keep my keto casserole dairy free, but you can use any plant-based milk, dairy milk, or even heavy cream if you like.

Last but not least, all that’s missing from this keto sausage egg casserole is the CHEESE! Sprinkle a generous helping of shredded cheddar on top, or any cheese you like. Or, feel free to stop here and omit the cheese if you’d rather keep your keto breakfast casserole totally dairy free.

To cook, bake in the oven at 350°F (180°C) for 35-40 minutes, until the eggs are set and the cheese is nice and melted. Allow to cool slightly before slicing and serving fresh, topped with hot sauce or your favorite condiments! Or, you can also store or freeze this keto egg casserole after it’s cooked.

To Store or Freeze your Keto Egg Casserole for Meal Prep

For keto meal prep purposes, cook as described above and allow to cool in the dish completely. Then, you can either keep your keto breakfast casserole in the dish to store whole, or cut it into portions before storing.

If your casserole dish comes with a lid, that’s great! Pop it on and storage is simple. But if not, simply cover the dish with whichever food wrap you prefer—foil, plastic wrap, or a plastic alternative like beeswax wraps.

Or, slice your cooked keto egg casserole into portions, then package them individually in airtight containers or zip-top bags. The advantage of this for freezer meal prep purposes is that you only need to thaw as many portions as you need each day, rather than thawing the entire casserole.

Once your keto casserole is covered in the dish or packaged into portions, you can store in the fridge for 2-3 days.

Or, if your dish/prep containers are freezer-safe, freeze for up to 3 months! Before reheating from frozen, be sure to transfer your frozen keto breakfast casserole or casserole portions into the fridge to thaw on the night before you want to eat it.
