This easy keto breakfast casserole with bacon, egg, and cheese is about to change your weekday meal prep game. Not only does it involve minimal ingredients and only 2 net carbs per serving, but it also stores perfectly in your refrigerator.

The total cook time is just under an hour and you can do something else while it’s baking. Even better, the total time includes the cooking time of the bacon, so there’s no extra time needed.

During busy weeks you can cook this keto recipe with very little prep time. Pre-cutting the finished casserole to serving size will make it easy to grab a piece from the baking dish on your way out the door. Having a quick and convenient option every morning makes a huge difference when you’re just starting out on keto.

Feel free to customize this keto breakfast casserole by adding some of your favorite low-carb veggies like bell pepper or broccoli in addition to the green onions. You can also try adding avocado or zucchini, which is a great way to sneak in additional dietary fiber and nutrients. Don’t be afraid to mix things up and try a variety of cheeses, or substitute the bacon for ham or breakfast sausage.

Along with being easy to make, this keto breakfast casserole is gluten-free, soy-free and sugar-free. But you might be wondering if the cheese is a good idea. Read on to find out why this recipe works, and get ready to enjoy a healthy start to your day the keto-friendly way.

Is Cheese OK on Keto?

This is a very common question and the answer is “it depends.” There’s a lot of confusion about dairy products. While low-lactose and high-fat dairy is acceptable on keto, low-fat dairy products are not.

Why? Because they usually contain way more carbs than the high-fat versions.

For many years, saturated fat was considered harmful for your heart health, so organizations such as the American Heart Association began recommending eating less saturated fats[*]. However, recent studies have debunked this concept, showing no significant link between saturated fat and the risk of heart disease. As it turns out, including healthy fats in your diet has many health benefits [*].

When buying ingredients for this keto recipe, you’ll want to make sure to get full-fat sour cream and heavy whipping cream. It’s not just cheese where you need to be vigilant about fat content.

Remember: Fat is fuel. You want all the fat in cheese, and it’s important to opt for fat that is high quality[*]. It’s best to avoid low-fat yogurts and shredded cheeses, as well as items made with skim, 1%, or 2% milk.

Cheese is one of the most common foods that people stress about when considering a lifestyle change like keto and other low-carb diets. But the only thing you need to worry about is depending too much on cheese as a food source. And avoiding dairy altogether if you have a dairy allergy or sensitivity.

Health Benefits of Cheddar Cheese

You might not think of cheddar cheese as a health food, but take a look at the nutritional information below. There are plenty of health benefits thanks to its dense nutrient content per cup.

High in Calcium and Vitamin D

These essential minerals may help protect your body from chronic diseases like diabetes, heart disease, high blood pressure, and other cardiovascular diseases[*].

Vitamin D helps your body absorb calcium, and you need both to build and maintain strong bones, in addition to supporting your muscles, nerves, and heart. Calcium deficiency may lead to osteoporosis, a common ailment especially among adults over the age of 50[*].

Dental Health

Calcium and vitamin D also promote dental health by supporting your gums and teeth. Most adults don’t get enough of either of these[*], which is why it’s important to make sure you’re consuming enough through food like full-fat dairy products[*].

Loaded with Vitamin A

Vitamin A, which the body converts from beta carotene, is vital for promoting eye health. It’s an antioxidant that may prevent eye dryness and night blindness and has been shown to guard against loss of vision caused by age-related eye diseases[*].

Contains Zinc

Zinc is an essential trace element that you need in small amounts every day. It supports growth and development as well as brain function. It also boosts your immune system, helps with hormone function, and aids your reproductive system.

It acts as an anti-inflammatory agent, which may help protect against chronic diseases like heart disease[*]. When you have a zinc deficiency, you may feel constantly tired or get sick frequently.

Supports Blood Health

Many nutrients that keep your blood, bones, and muscles healthy are found in cheddar cheese. In particular, vitamins B6, E, and K all support blood health in various ways. Vitamin B6 and E help your body form red blood cells, and without vitamin K, blood would not stick together[*].

Boosts Immunity

Probiotics, the live bacteria that maintain the healthy balance of microorganisms in your gut, are essential for boosting the immune system. Not all cheeses are good sources of probiotics, but cheddar happens to be one of them[*]. The vitamin D content also supports healthy immune system function.

Protects From Free Radical Damage

Free radicals can be harmful to the body because they damage DNA, cellular membranes, and fats stored within blood vessels. This damage has aging effects on both the body and mind[*]. The best way to prevent free radical damage is by eating foods rich in antioxidants and vitamins like cheddar cheese.

Packs the Protein

One ounce of cheddar cheese contains 7 grams of complete protein. Not only is protein filling and keeps you satiated throughout the day, but it builds and repairs tissue, and is essential for muscle, cartilage, and skin health[*].

The Perfect Low-Carb Breakfast

Combining cheddar with high-fat bacon, eggs, and cream, you’re sure to have a filling keto breakfast with 38 grams of total fat, 43 grams of protein, and 2 grams of net carbs per serving.

This keto breakfast casserole is easy to make with very few ingredients, and you’ll have leftovers for days. Simply store in the fridge for the week.

If you have a few extra minutes or want to enjoy a leisurely meal, you can whip up other brunch recipes like cauliflower hash browns or keto pancakes while you cook this casserole recipe.

You could also whip up some keto chocolate chip muffins for snack or tea time if you want to break up all those savory flavors. The bottom line is that this delicious recipe goes well with just about anything. Be sure to check out these recipes for more keto-inspired cooking ideas.

      1. It says 55 minute cook time at the top and 35 minutes in the instructions at the bottom. Is this a typo?

      2. Hey Tammy, yes I believe that’s a typo. Go with 35 minutes and then check to make sure it’s cooked all the way through – may need a bit more time depending on your oven.

  1. Why does it say cook time 55 minutes at the top but near the end in the instructions it says “cook for 35 minutes, checking after 30 minutes?” should that say 55 in the paragraph? or should it say 35 at the top?

    1. Hey Kelly, I believe it’s a typo. I would go with 35 minutes and check at that point. May need a bit more time depending on your oven. When its golden brown and not jiggly anymore it should be done 🙂

      1. I don’t think it’s a typo. I believe it is also counting the cooking time for the bacon.

  2. I’m not seeing a recipe, only paragraphs talking about how good it is for you. Even when I click “Jump to recipe” at the top, it just scrolls me down to the bottom of the page where it only says “[simple-recipe]”.

    1. Hi Ben, our developers are working on site updates and fixing recipe issues. The recipes should be back tomorrow! Check back in a bit. Thank you!

  3. Delicious and so easy to make. Keeps me full and satisfied till lunch. Love this casserole, highly recommend it.

  4. I must express my thanks to this writer for bailing me out of
    such a crisis. After looking throughout the online world and
    coming across ideas which were not pleasant, I assumed my life was
    done. Being alive without the strategies to the problems you have resolved
    all through your main article content is a critical case, as well as the ones
    which might have negatively damaged my entire career if I had not noticed your web blog.
    That training and kindness in touching the whole lot was
    excellent. I’m not sure what I would’ve done if I
    had not come across such a step like this. I am able to now look ahead to my future.
    Thanks a lot very much for the expert and results-oriented guide.
    I will not be reluctant to suggest the sites to any individual who needs guidance on this
    topic

  5. Can I just mix the cheese into the egg mixture. I would think a cheese layer at the bottom would stick or not mix well. Thoughts?

  6. What’s the easiest way to lock this in Carb Manager and can someone please verify what a serving of this is?

    1. @Natalie You lock this on your Carb Manager by copying the website address into the import tool. On another note, this recipe makes 8 and the macros are for 1 serving.

  7. I would love to make this, but we don’t eat any pork in our house. Can you possibly suggest anything to substitute? Thanks
