  4. Large pot for steaming broccoli

Keto Broccoli Casserole with Heavy Cream: A Step-by-step Recipe


  • 1 large head of fresh broccoli florets
  • 1 cup heavy cream
  • 1/2 cup sour cream
  • 1/2 cup parmesan cheese
  • 1 cup mozzarella cheese
  • 1 cup sharp cheddar cheese
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon garlic powder
  • Optional: 1 cup of cooked chicken breast or rotisserie chicken (for a hearty keto chicken broccoli casserole)


  1. First, preheat your oven to 350°F (175°C) and grease your casserole dish with olive oil.
  2. Steam the fresh broccoli florets until they're just tender. The best way to do this is to bring a large pot of water to a boil, add the broccoli, and cook for 3-4 minutes. Be careful not to overcook; you want the broccoli to retain some of its bite. Once steamed, drain the broccoli well, ensuring you remove excess water.
  3. While the broccoli is steaming, prepare the cheese sauce. In a small saucepan over medium heat, combine the heavy cream, sour cream, parmesan cheese, half of the mozzarella cheese, and half of the sharp cheddar cheese. Stir in the black pepper, garlic powder, and onion powder.
  4. Stir the mixture constantly until it becomes a smooth cream sauce. Remove from heat.
  5. In a large bowl, combine the steamed broccoli with the cheese sauce. If you're adding chicken to make a keto chicken broccoli casserole, now is the time to add it. Mix well, ensuring each broccoli floret is well-coated in sauce.
  6. Pour the broccoli mixture into the greased casserole dish, spreading it out evenly. Sprinkle the rest of the cheese over the top.
  7. Bake in the preheated oven for 15-20 minutes, or until the cheese is melted and bubbly.
  8. Let the casserole cool for a few minutes before serving. Garnish with fresh parsley for a pop of color and added flavor.

Quick and Easy Keto Recipes: Time-Saving Tips

The Keto Broccoli Casserole with Heavy Cream is not just delicious, it's also an easy recipe that doesn't require you to spend all day in the kitchen. And who doesn't love quick and easy keto recipes, right?

If you're like me, always looking for ways to save time in the kitchen, you'll appreciate these tips. First, you can use a rotisserie chicken from your local grocery store. Not only does it save you time, but it also adds a lovely flavor to the dish.

Second, consider investing in an instant pot or a similar multicooker. It's a real game-changer when it comes to steaming your broccoli florets, not to mention a variety of other cooking tasks. You can also use it to quickly cook chicken breast if you prefer it to rotisserie chicken.

Options for Leftovers: Keto Broccoli Casserole Reimagined

Leftovers are often inevitable, especially when cooking for a small family or just yourself. The good news is, our Keto Broccoli Casserole with Heavy Cream is just as tasty the next day.

Remember, you can store it in an airtight container in the refrigerator and it'll stay good for 3-4 days. For a quick lunch, you can serve a portion of the casserole over some cauliflower rice for a low-carb, high-fat meal that is completely in line with keto guidelines.

However, if you want to change things up a bit, you can convert the leftover casserole into a cheesy keto broccoli soup. All you need to do is add some chicken broth to a portion of the casserole, heat it up on the stove or in a microwave, and voila - you've got yourself a hearty, creamy soup!

Perfecting the Keto Casserole: Experiment with Flavors

Another beautiful aspect of this recipe is the room it provides for experimenting. You can easily alter the flavors of your keto broccoli casserole with simple additions or changes.

For example, if you want to add a bit of crunch, try sprinkling the casserole with crushed pork rinds before baking. Or for a slightly different flavor profile, replace some or all of the broccoli with cauliflower florets.

Perhaps you want a bit of a spicy kick? Add some crushed red pepper flakes to the cheese sauce. The possibilities are as endless as they are delicious!

In conclusion, the Keto Broccoli Casserole with Heavy Cream is not only a treat for your taste buds, but it's also versatile, easy to prepare, perfect for repurposing leftovers, and ripe for flavor experiments. So, whether you're new to the keto diet or you're a seasoned pro, this dish is bound to become one of your go-to keto recipes! Happy cooking!
