Loaded Keto Broccoli Cheese Casserole {Low-Carb}

On any specialty eating plan, you might find yourself turning to the same foods over and over. 

On the list of keto foods, for many people, that’s a casserole. Most casseroles are topped with breadcrumbs, crushed crackers, or other carb-packed ingredients that we try to avoid. 

And that can be a challenge during the holidays with all the parties and social occasions full of foods that can derail our diet.

That's where this broccoli and cheese keto casserole comes in. It's one of our favorite keto Thanksgiving side dishes that delivers on flavor while enabling you to stick to your ketogenic diet.

This Broccoli Cheese Keto Casserole Is...

  • Satiating: While we developed this recipe as a low-carb side dish, you can serve it as a weeknight meal for a great make-ahead keto casserole that’s packed with satiating, delicious fats. 
  • High in calcium: There are a few sources of calcium in this recipe, from the cheeses to the broccoli. 
  • Keto-friendly and low-carb: This recipe skips the carb-heavy breadcrumbs and starchy potatoes in most casserole recipes and delivers a meal with nearly 30g of fats and less than 5g of net carbs to keep you on track.


The fresh broccoli is first drizzled with some healthy FBOMB Olive Oil and mixed with full-fat cream cheese, cheddar cheese, mayonnaise, and garlic. 

It’s then baked into a creamy, cheesy luscious casserole that’s topped with Parmesan cheese, green onions, and crushed Cheddar Keto Krunch for some extra flavor and crunch. 

Keto Krunch cheese crisps are made from premium fresh milk sourced from local family farm cows that are ethically treated. 


Low in Carbs, High in Nutrients

This recipe is packed with vitamins, minerals, and other compounds that have been shown to do a great deal of good within the body. 

For example...

Olive oil contains polyphenols that research shows may support healthy cholesterol levels and boost the immune system [*][*]. 

Broccoli is a star ingredient in this recipe and provides it with its delicious flavor. But it also shines for another reason: broccoli is high in fiber, minerals, and vitamins -- one of which is vitamin C. 

Just 100g of broccoli contains 148% of your recommended daily intake of vitamin C. Research has found that vitamin C supplementation can increase the levels of antioxidants in the blood [*].
