Would you believe that my parents never made me eat broccoli as a kid?

I honestly don’t think I ever even tasted broccoli until I was a teenager.

Which, hey, I’m not complaining. Broccoli was scary and green looking and I was super picky. My parents picked their battles.

But now? I LOVE broccoli. It’s probably my favorite veggie and I often eat it steamed with just a sprinkling of salt. No butter, no cheese, just good ol’ broccoli.

Sometimes, though, you’ve got to get a little fancy with your vegetables and that’s where this easy broccoli cheese casserole comes into play.

Y’all are going to love how cheesy and melty and flavorful this low carb broccoli casserole recipe is!

ingredients for broccoli cheese casserole.

Fresh Broccoli – You’ll note that I’m a fan of the fresh broccoli over the frozen! It just tastes better, but I do understand the convenience of the frozen kind. If that’s what you’ve got, it should work. I’ve just never made it myself in this recipe.

Cheese – This broccoli and cheese casserole is loaded up with rich cream cheese, freshly grated cheddar cheese, and some grated Parmesan cheese! That’s going to add tons of creamy, decadent cheesy flavor to this casserole.

Mayo – It’s going to add even more creamy flavor to this keto casserole.

Seasoning – You don’t need many seasonings for this casserole. The rich, cheesy flavors with the broccoli pretty much do most of the work but we do like to mix in some garlic powder, salt, and ground black pepper!

Why We Love This Recipe:
  • Broccoli and cheese is a classic recipe that just about everyone can enjoy, including the kids!
  • It’s an easy casserole recipe that you can put together in no time.
  • With all that rich, creamy cheese nobody will even notice that this is a keto casserole.

🥦 How To Make Broccoli Casserole:

  • Broccoli – We’re starting with fresh broccoli for this recipe, because I personally think it has the best taste and texture. I do usually buy pre-cut broccoli florets in the produce section, but a head of broccoli works just as well. Chop the broccoli into small florets.
  • Steam – You’ll start out by steaming the broccoli lightly, either in a stove top steamer or in the microwave. For this recipe, I nearly always opt for the microwave, just because it’s easy. Pop your broccoli into a large bowl with two tablespoons of water, cover tightly with plastic wrap, and microwave for 2 minutes.
  • Cheese – You’ll mix together cream cheese, grated cheddar, garlic powder, salt, and pepper.
  • Mix – Scoop that mixture right on top of your hot and steamy broccoli and start stirring. The mixture should melt right into the broccoli pretty quickly as you stir.
  • Bake – Transfer this to a baking dish and sprinkle the top with Parmesan cheese. Bake it up and you’ll have this decadent broccoli and cheese casserole that the whole family will love! This easy broccoli casserole is ready to go in just about 20 minutes.Serve alongside some grilled chicken or steak with a side of keto coleslaw!

      1. What is the service size in weight or volume? A serving size of “1” doesn’t tell you much…

        1. Karly Campbell

          We didn’t measure by weight or volume, we just divide into 6 equal servings.

    1. Erin Lundgren

      I use frozen all the time and just slightly defrost is before hand. This is the best broccoli recipe 😛

  1. Jennifer Burton

    Great recipe! Exactly what I was looking for! I did half the cream cheese based on some comments and to compensate I was a bit generous with the cheddar. So delicious. I will definitely make again regularly.

  2. Kim Platzer

    Oh Yeah…. I have made it twice…. first time exactly and the second time went with less cream cheese and several different types of cheese to add, like havarti and swiss along with the cheddar and parm…. next time I am going to add chicken….. thank you

  3. Full disclosure…big broccoli fan. Made this a few months ago following the recipe with the addition of sautéed mushrooms and shallots. As written, found the cream cheese too much and the texture a bit gummy as others mentioned. So took another try, post-thanksgiving. This time I only had manchego (leftover from the thanksgiving cheeseboard) which I think helped since it’s a bit less oily than cheddar. Cut the cream cheese way down, added a bit of Dijon mustard for some sharpness and dash of nutmeg which is typical for a cheese sauce. Added the cheese mixture into the warm sauté pan with the cooked shallots, mushrooms and thyme. Which helped loosen it up. Then folded in the broccoli and a good helping of leftover shredded thanksgiving turkey. Dropped into the casserole pan and everything was perfectly coated. The turkey and broccoli where the main stars and the cheese was there, not overwhelming and held it all together on the plate. The original recipe is a great start to all kinds of interpretations.

  4. Would this casserole freeze well? Perhaps even before cooking? Trying to make ahead for family dinner.

    1. Karly Campbell

      Hi Gloria! I’m honestly not sure how well this one would freeze. I think it’d probably be fine, if you like frozen broccoli. We’re not fans here – fresh is always our go to. But if you don’t mind it, it’d probably work okay.

    2. Don’t use cream cheese if you are going to freeze, otherwise the cream cheese will separate. Maybe if you make a roux cream sauce it won’t separate, but it’s a gamble.

  5. We will be traveling for Thanksgiving. Could I make this wonderful sounding dish in advance? And how would I do that?

    1. Karly Campbell

      Hi Patty! We personally don’t super love reheated broccoli – it tends to get a bit mushy. However, you definitely CAN make this ahead, if that doesn’t concern you. I wouldn’t make it more than a day in advance.

  6. This was a perfect low carb side to go with the ribs my husband smoked today. I followed the recipe exactly and I don’t think anything needs to be changed on it.
