This keto breakfast casserole with ham and eggs is packed with healthy vegetables too! A great low carb breakfast idea that is easy to make ahead!
There are so many variations on a breakfast casserole recipe out there, and I’ve tweaked mine many times over the years. This is my favorite version currently, though because it’s low carb and easy!
The biggest difference between a keto breakfast casserole and one that’s high in carbs, is that this recipe doesn’t contain hashbrowns or any form of potatoes. It also replaces the milk used in traditional recipes with heavy whipping cream. Milk has quite a bit more carbs than heavy whipping cream, so I try to eliminate it wherever I can in recipes.
Ingredients needed for this recipe: eggs, cubed ham, cheese, heavy whipping cream, assorted chopped veggies (I used spinach, mushrooms, red peppers, green peppers and onions)
How to Make a Keto Breakfast Casserole with Ham and Eggs
Start by spraying a 9×13 pan with non-stick cooking spray.
Then start chopping your veggies. This is a great recipe to use up vegetables you may have that are on the verge of going bad. I don’t pay a lot of attention to what veggies I’m using. I just go through my fridge and use the ones that have been there for a few days and need used up.
This recipe ended up turning into a Farmer’s Breakfast Casserole, because I had such a delicious variety of veggies to use. I finely chopped a small onion, about 3/4 cup of mushrooms, half of a green pepper, half of a red pepper and about 1.5 cups of spinach.
Once you have all your veggies chopped, layer them as evenly as possible in the bottom of the pan. I actually tend to add them to the pan as I chop them. That way it’s easier to keep each ingredient evenly spread.
Chop your ham into bite-size pieces and layer them over you vegetables.
Pour the egg mixture evenly over the veggies and sprinkle the remaining cheese on top.
Bake at 375 for 30-35 minutes until the eggs are set in the middle. You can test by inserting a knife in the middle of the egg bake and making sure it comes out clean. You can also just give the pan a little jiggle to make sure the center is set.
It’s not exactly the most photogenic food, but it’s filling and healthy and that’s much more important.
We slice our 13×9 pan into 3 columns and 5 rows for 15 total servings. The nutritional information in the recipe is based off 15 servings, so be sure to recalculate if you cut yours differently.
Keto Breakfast Meal Prep
I’ve been making an egg casserole bake every Sunday night because it’s the perfect low carb meal prep for the rest of my week. I bake it as soon as it’s assembled and then just cut a slice each morning for my breakfast.
It reheats well in the microwave and only takes about 1 -1.5 minutes. You can also reheat in a toaster oven but that will take a little longer till it’s heated through.
This casserole lasts us about 4-5 days (there are 4 of us but not everyone has a slice every morning).
If you think it will take longer than that for you to finish it, you can always freeze individual slices. It freezes really well! I just wrap each individual slice in plastic wrap and then store them in a large freezer bag. Pull one out the night before you want to eat it and just let it defrost in the refrigerator. Heat up as normal the next morning!
Substitutions to Egg Casserole Bake
Eggs: You can easily use a refrigerated egg substitute in place of whole eggs. Also, don’t skip this recipe if you only have 11 or even 10 eggs. It will still taste great and cook up the same way, it just will be a little bit less for each portion.
Cheese: I’m not strict Keto, so I use pre-shredded grated cheese. Most people who are strict Keto advise against this since the grated cheese is tossed with a starch to keep the pieces separated. You can easily buy a block of cheese and grate your own if that is a concern for you. I used sharp cheddar cheese for mine, but feel free to use your favorite shredded cheese.
Ham: You really could leave this out completely and just have a vegetable breakfast casserole. You also could substitute it for any other meat of your preference. I often will use cooked ground sausage instead. Crumbled bacon is another great breakfast option!
Heavy Whipping Cream: If you aren’t worried about carbs, feel free to just use milk instead of heavy whipping cream. Another option would be to use Almond Milk which is lower in carbs than regular cow’s milk.
Vegetables: Please feel free to use nearly any other vegetable you would like! I used mushrooms, spinach, peppers and onions. You could pick one or two from there or add your own. Asparagus and broccoli are great options too! I usually try to have 2-3 cups of chopped veggies, but I don’t worry about it if I have less than that. You could even saute your veggies first if you prefer. But just look how gorgeous those fresh veggies are!
