This Keto Breakfast Casserole is low-carb and gluten-free. Filled with ham, cheese and veggies, this easy breakfast casserole easy to customize and perfect for any time of day. 

Having an easy Keto breakfast can help keep you on track when you are trying to eat fewer carbs. Sometimes I can get by with just a few hard boiled eggs but sometimes I want something that has a little more substance. 

When you think breakfast casserole you might think hash browns or bread but with this casserole you won’t miss those carbs. This low carb breakfast casserole with ham is sure to become a favorite!

Ingredients Needed

Green Bell Pepper – Green bell peppers have about 5 net carbs per one cup of diced pepper. Red and yellow peppers contain about 6 net carbs. 

Mushrooms – You can use white or cremini mushrooms. 

Diced Ham – You can buy pre-packaged diced ham or cut up deli sliced ham. 

Eggs – The base of the casserole. Eggs are high in protein and fat making them the perfect keto casserole ingredient. 

Cream – Heavy cream is a great ingredient to keep in your fridge when you are following a low-carb lifestyle. You can also use coconut cream if you want a non-dairy option. Cream really makes the breakfast dish nice and fluffy.

Shredded Cheese – I used mild cheddar for this casserole but feel free to use your favorite. I also enjoy using half Monterey Jack and half Pepper Jack cheese.

• This recipe begins by melting butter in a skillet. Add in diced peppers and mushrooms. Cook for 2-3 minutes and then add in diced ham. 
• Spray a casserole dish with non-stick add ham mixture. 
• In a large bowl, whisk together eggs, cream, salt and pepper. 
• Pour the egg mixture over ham and vegetables in the casserole dish. 
• Sprinkle cheese over top and then place in the oven.
• Bake for about 25 minutes or until the top starts to turn golden. 

Want a little extra protein…serve with a side of Air Fryer Bacon. 

Cooks tips

• This recipe uses butter but you can use your favorite “fat” like avocado oil or olive oil. 
• I prefer shredding my own cheese. The pre-packaged cheese can sometimes contain preservative ingredients that you might want to avoid. 
• This recipe is also great served with diced avocado, diced green onions, sour cream and even salsa on top. 
• Once cooked, you can cut into squares and wrap individually for meals for the week.

How to freeze

When I am making this low carb breakfast casserole I will often double the recipe and freeze one of the casseroles. 

Freeze Before Baking: If you would like to freeze this before baking, prepare according to instructions but don’t bake. Cover tightly with plastic wrap and then and then 2 layers of foil and freeze for up to 2 months.

Let thaw in refrigerator over night and then bake as directed. 

Freeze After Baking: To freeze after baking, let the breakfast casserole cool completely and then wrap with plastic wrap and then foil and freeze. I also love cutting the casserole into portions and freeze individual portions by placing in freezer friendly container. 

Thaw over night in the refrigerator. Place in oven to reheat. 

Variations

I love this casserole because you can easily change up the ingredients for a little variety.

Veggies– Other vegetables to try, diced onion, chopped broccoli, chopped spinach, and diced zucchini. 

Meat – Crumbled breakfast sausage and chopped bacon are great options. You could even add in with the ham for extra protein.

Cheese – So many different great cheese choices for this casserole. Cheddar, Mozzarella, Monterey Jack and Swiss are all delicious!  

Hot Sauce – If you would like to add a little spice, add a few drops of your favorite hot sauce into the egg mixture. It won’t make the meal too hot, it adds a nice flavor.
