Gluten-free Low-Carb Broccoli and Cheese Casserole is a crowd-pleasing side dish!


The more I have the chance to spend time in different areas of the country, the more I realize that where you’re from is often depicted in the way you drive.

When my sister lived in North Carolina she told me all the about what she liked to call Southern charm. She said everyone was sweet as pie until they got into their car and then it was no holds barred. It’s not that there was a lot of horn-beeping like what we grew up with in New York, but mostly people hanging their heads out car windows to scream profanities and what they feel is the other driver’s just desserts, followed by bless your heart!


In Florida, I’ve seen some actually scary stuff go down. Once I saw a guy cut a lady off in a really dangerous way so the lady almost got in an accident; she flipped him the bird and then they both had to stop at a red light (of course his car right in front of hers because he had just cut her off). The guy who cut the lady off got out of his car and started pounding on her window, screaming curse words and making death threats. Omg, I was scared for her. Luckily, it was a short light and as soon as it turned green, she waited for traffic to pass and then she was able to scoot out from behind the guy’s car and go on her way. Whoa.

Surprisingly enough, here in DC there’s not a lot of horn-beeping or profanities being slung; there is just so much traffic it’s expected that you’ll be cut off or nearly hit every time you’re brave enough to venture out in your car.

And this craziness wasn’t even anytime near the Christmas shopping season! We all know that late November straight through until Christmas it gets even worse out there. Be careful, people. Remember that it’s someone’s wife, son, grandpa, mom, etc. before you decide to be reckless or inconsiderate behind the wheel. (And my PSA is officially over, lol.)


With all the stress that goes on outside, sometimes coming home and cooking or (coming home to a homecooked meal) is the best kind of stress relief. Especially if said homecooked meal involves veggies swimming in a creamy cheese sauce that also happens to be low-carb. This dish is quite similar to my Low-Carb Cheesy Leftover Turkey (or Chicken) Jalapeno Popper Casserole, which is weird because I actually made and photographed this recipe first. There are a couple significant differences, namely, that this one has broccoli instead of meat and this one is lacking spicy heat; other than that, these two dishes could almost be twinsies.

This recipe is a mashup of the broccoli and cheese sauce that I grew up loving and broccoli cheddar soup (you know, from someplace like Panera; speaking of which, I recently had the broccoli cheddar soup there and it wasn’t nearly as good as I remember it being. It had an overly salty, processed taste, not the homemade flavor that you’ll get from something like this casserole). Anyway, the flavors going on here are a great combo, and the perfect way to get picky eaters to ask for more broccoli.

Like so many side dish recipes I’ve been sharing lately, this one would be a good addition to your holiday spread. To make it red and green festive for Christmas, sauté a chopped red pepper along with the onion and celery.


Low-Carb Broccoli and Cheese Casserole {Gluten-Free}
Prep time: 
Cook time: 
Total time: 
Yield: 8 servings
Regular broccoli and cheese is taken to the next level in this creamy casserole.
  • Unsalted butter, to grease the dish
  • 6 to 8 cups broccoli florets
  • 2 tablespoons unsalted butter
  • 1 medium onion, diced
  • 2 medium-large stalks celery, diced
  • 1 clove garlic, minced
  • 8 oz (225 g) cream cheese, cubed, at room temperature
  • ½ cup (120 ml) heavy cream
  • 1 teaspoon Dijon mustard
  • ¼ teaspoon salt
  • ¼ teaspoon ground black pepper
  • 8 oz (225 g) shredded white cheddar, divided
  1. Preheat oven to 400F; grease a 2.5-quart casserole dish with butter and set aside.
  2. Bring a large pot of water to a rolling boil; add the broccoli and cook 60 seconds, then drain well.
  3. Add the butter to a large, deep skillet over medium heat; once melted, add the onion, celery, and garlic. Cover the skillet and cook until the veggies are softened, about 6 to 8 minutes, stirring occasionally. Stir in the cream cheese until melted, and then stir in the heavy cream, Dijon, salt, pepper, and half of the cheddar. Once the cheese is melted, stir in the broccoli.
  4. Pour the mixture into the prepared dish and top with the remaining cheddar. (At this point, you can let it cool to room temperature, cover it, and keep it in the fridge for up to 3 days before proceeding.)
  5. Bake (uncovered) until bubbling and golden on top, about 20 to 30 minutes. (You can run it under the broiler for a little bit at the end if you want it even more golden on top, but stay with it because it can burn quickly!)

    We had a bunch of broccoli that we needed to use and we’re on a low-carb diet, so I googled for some recipes. Most of them had either rice or pasta in the recipe, so I was happy to find yours: it was terrific! Since we had a bag of Mexican Style Four Cheese Blend already in the fridge, so we used that instead of the cheddar. Next time I’ll use sharp cheddar as that cheese is a favorite. I had already grilled some chicken breasts earlier in the week, so I was able to use them as well. Thanks Faith!

  2. I think this would be good with some added brown rice, or served on top of some rice. Or a baked potato!

    Thank you.

  3. Mmmh, that looks so scrumptious! Broccoli gratins are so delicious and this one seems just perfect.
