Loaded Cauliflower Bake

When it comes to easy recipes and rich, filling food, it’s hard to beat a casserole dish. If you’re just starting out on your keto journey, you probably quickly realized that casserole bakes are one of the most popular main dishes — and this loaded cauliflower casserole is no exception.

This comfort food is one of the best ways to make everyone, even the picky eaters, load up on veggies without even noticing. It’s hassle-free and involves very little cleaning afterwards.

This keto cauliflower casserole is crispy, cheesy, and will surely become a household staple.

Health Benefits of Loaded Cauliflower Casserole

This loaded cauliflower casserole recipe is not only worry-free if you’re following a keto or low-carb diet, but it’s also incredibly nutritious and loaded with health benefits. Here are a few nutrition facts.

#1: Can Improve Bone Density

This baked cauliflower casserole is also packed with delicious, calcium-rich dairy products. Cheese is not only a great source of protein but also one of the best ways to increase your daily amount of required calcium to keep your bones and teeth healthy[*].

Whenever possible, always opt for grass-fed cheese to avoid harmful additives and get extra richness in important compounds such as CLA and omega 3 fatty acids[*][*].

Green onions, also known as scallions, are also in this dish and they’ve been used as a popular remedy in Asian folk medicine for thousands of years. Eastern herbalists commonly use them to fight colds and alleviate headaches, indigestion, and insomnia.

This veggie comes packed with both vitamin C and vitamin K, which are crucial to bone health. Both these vitamins work together to strengthen and maintain bone density, helping to prevent bone degenerative conditions such as osteoporosis[*][*][*].

#2: May Promote Heart Health

This loaded cauliflower casserole delivers a great number of vitamins and nutrients, but one of the most prominent is folate.

One large head of cauliflower delivers an astounding 479 grams of folate goodness. One particular study has shown that folate can help to lower the risks of stroke and other cardiovascular diseases[*].

Cauliflower is also a powerhouse of other important nutrients, such as lutein and zeaxanthin. These particular compounds have been shown to be greatly beneficial to cardiometabolic health and to prevent oxidative stress[*].

#3: Can Help Lower Blood Sugar Levels

The two veggies used in this recipe come packed with high amounts of vitamin C. Vitamin C is quite unique because your body cannot produce it. It’s a very important nutrient that contributes to many vital functions in the body[*].

According to a study published in 2011, a higher consumption of vitamin C may contribute to lower high cholesterol and blood pressure levels, therefore having a positive impact on those affected by type 2 diabetes[*].

#4: Can Help Improve Skin Health

Green onions provide around 9 milligrams of vitamin C per half-cup serving. This nutrient plays an important function in synthesizing collagen, the most abundant protein found in the human body. It plays a crucial part in bone, muscle, skin, and tendon formation[*].

Vitamin C is also an important antioxidant that protects your cells and promotes healthy tissue growth. It assists in wound healing and, when combined with vitamin E, can protect the skin against UV irradiation[*].

#5: May Help Lower the Risk of Colon Cancer

There’s a reason why cauliflower is the king vegetable in keto. Not only is it extremely low-carb but also half of its total carbohydrate content is dietary fiber.

Fiber plays an important role in the proper function of your digestive system, particularly your intestines.

New research is now showing just how important the large intestine is and how closely it’s linked to proper immune function as well as brain performance. It’s even nicknamed “the second brain”[*].

Colon cancer is the third most common cancer in the world and it may be avoided if you follow a healthy diet and a balanced lifestyle. Suitable intake of dietary fiber can help keep your colon working in an optimal way, helping to lower the chances of cardiovascular disease, obesity, diabetes, and colorectal cancer[*][*].

The next time you want an extra boost of nutrition for your salads, omelets, or stir-fries, this loaded cauliflower casserole will become your new favorite low-carb side dish.

Recipe Variations

This casserole is incredibly versatile and can be boosted in a number of ways. Here are some ideas for making this recipe your own.

  • Add sour cream: If you really like a creamier recipe, adding some sour cream can turn it into an even more decadent dish, without the guilt.
  • Save time: To make this recipe even quicker, using frozen cauliflower is a great option. Just use it the same way as you would fresh cauliflower.
  • Heat it up: For a spicy twist, chop some jalapeño peppers and sprinkle on top. For medium-heat, remove some of the seeds, otherwise it will become a very hot dish.
  • Mix up seasonings: To boost the flavor and change things up, throw in some minced garlic or even garlic powder. Or sprinkle it with chopped chives after you’ve removed it from the oven for extra flavor and nutrients.
  • Be cheesy: When you’re choosing which cheeses to use, sharp cheddar cheese, Monterey Jack, or parmesan make for flavorful and rich options.

  1. The macro panel on the right lists 300g of carbs for the meal. I think that’s a typo. If the recipe has 5.8g of carbs per serving and serves 4, it should be 23.2 for the whole dish.

  2. I won last night’s casserole cook off! Even with so many people who were afraid to try anything “Keto”. Thanks. This is definitely delicious comfort food.

  3. all the recipes say that the serving size is as prepared. I’m following calories also. How do I know the exact serving size?

  4. Paula to get exact serving size you might need to weigh every ingredient in either oz or g as you enter the ingredients into your calorie counting program. That way your calorie counting program will be most accurate as it builds the recipe.
    Then weigh the total finished product before placing in the baking pan.
    If you a enter the recipe into a program like My fitness Pal, then 1oz of the prepared recipe could equal 1 serving. So if the prepared recipe weighs 14 oz then there are 14 servings in that recipe.
    If you eat 4 oz of the recipe you will log 4 servings in MyFitnessPal and that will give you the most accurate account of calories and macros.
    It’s a bit fiddly but once it’s entered you have it forever.

  5. I’m on the keto diet. How big is a serving? If it serves 4 how big are the serving sizes if it’s in a 9×13 in. Pan?

  6. Just made this, my kids and husband ate is and asked for more…. so it’s a Win in any book. I did not book the cauliflower, I roasted it with the bacon on top(I thought it might make the dish a bit watery) glad I did, the roasted cauliflower flavor is amazing.

  7. Why cant it be simpler and talk in cups , half and quarter cup. Also tsp tbsp, counting calories and using my fitness pal makes everthing so much more difficult and time consuming?

  8. Recipe is delicious. I am logging it into My Fitness Pal. Can you clarify the macros for 1 cup of this recipe for me? Thank you

  9. To meal prep this would I just make it up to the point of cooking and then throw in fridge until day I want to eat it?

  10. Made this last night and my whole family loved it. Super easy and all ingredients already in my kitchen.

  11. Made this with a mix of broccoli and cauliflower. Put florets on cookie sheet, tossed with evoo, sprinkled Himalayan salt and roasted them at 450f for about 20 minutes. Let them cool before putting in casserole pan/baking dish. Very Good -Thanks!!

  12. Made this recipe twice and once with Broccoli. Cheryl would not eat Cauliflower, she loves this recipe. For the Broccoli,Ijust poured the cheese sauce on top. Delicious

  13. trying to print the recipe and why does the “guides , products, recipes, blog , podcast , search pop up box enter into the printing. It blocks out
    half of your recipe. Any one else have this problem with printing

  14. Hello, I love your recipe and have served it on several occasions. Would you happen to know how to do this in an Instant Pot? I have one that has a saute/browning feature.

  15. Delish recipe – was a big hit at Thanksgiving! Will add this to my weekly menu! Love the idea of roasting the cauliflower first rather than blanching –

  16. This is delicious. Made it several times and always comes out well. Do you have an adaption to make this in an Instant Pot? I got one for Christmas and want to try this!!
