What You Need To Make This Keto Broccoli Casserole

  • Oven-safe casserole dish
  • Skillet
  • Bacon – bacon makes everything better!
  • Butter
  • Onion
  • Garlic
  • Heavy whipping cream
  • Broccoli – fresh is best!
  • Mozzarella
  • Parmesan
  • Xanthan gum (optional)

How To Make This Keto Broccoli Recipe

  1. Wash and trim the broccoli and steam it for about 3 minutes in the microwave on high or until the broccoli is bright green but still quite crunchy.
  2. Chop the bacon and fry it in a skillet. Set the bacon aside and remove all but 1 tbsp of bacon fat from the pan.
  3. Add the butter to the pan and sautee the onion and garlic in the bacon fat until the onion is translucent, about 5 minutes.
  4. Add the cream to the skillet and simmer for 3-4 minutes, allowing it to thicken slightly. Thicken with a pinch of xanthan gum if you like it a bit thicker.
  5. Add the bacon to the cream, and toss with the well-drained broccoli. Season with salt and pepper. Stir in the parmesan cheese.
  6. Pour this bacon, cream, broccoli mixture into an oven-safe casserole dish. Top with mozzarella and parmesan and bake at 400-F until the top is bubbly and brown. About 10 minutes.

How Do I Steam Broccoli?

Steaming broccoli is pretty simple.

  1. Start with a large glass or microwave-safe bowl.
  2. Add about 1/4 cup of water to the bottom of the bowl.
  3. Put the washed and trimmed broccoli, cut in pieces, into the bowl and cover tightly with plastic wrap.
  4. Microwave on high for 2-3 minutes then check. Continue on high in 1 minute intervals until it is cooked the way you like it.
  5. Be careful opening the plastic wrap – watch out for the hot steam!

Chef Jenn’s Tips To Make Keto Broccoli Casserole with Parmesan and Broccoli

  • Don’t overcook the broccoli! There’s nothing worse than mooshy broccoli. You want to steam it (see notes above) just a few minutes until it is bright green with still some crunch.
  • Change up the cheese – gouda, havarti, Swiss, pepperjack – whatever you’ve got will be fine!
  • Add a pinch of red pepper flakes for some extra heat
  • Xanthan gum helps this thicken up a little bit – don’t use more than 1/4 tsp – but is totally optional

What to Serve With This Delish Keto Casserole

Go for something kind of simple, so that this recipe can be the star of the dinner table. Bacon-Wrapped Pork Tenderloin would be a great choice, and so would this Garlic Steak & Mushrooms dish.

Is Keto Broccoli Casserole with Parmesan & Bacon Freezer Friendly?

Yes, you can freeze this dish.

But –

Once frozen and thawed, the broccoli is going to give off a fair bit of water and your nice creamy sauce could turn kind of soupy.

If that doesn’t bother you – go ahead and freeze this keto broccoli bacon casserole for up to three months in a freezer-safe container or zippered plastic bag.

Thaw it and heat it in the microwave.

Or, just enjoy this amazing dish fresh from the oven.

Is broccoli keto?

Yes! Totally keto. With about 3.5 net carbs per 1 cup serving, it’s a great choice for keto dieters. Rich in fiber, vitamins, and more, it’s a healthy veggie for anyone!

Can I use frozen broccoli instead of fresh in a casserole?

The easy answer is yes – just thaw it and drain it really well first. The more complicated answer is that frozen broccoli gives off a lot more liquid so your sauce could be more soupy.
