Cauliflower Broccoli Bake Ingredients

How To Make Cauliflower Broccoli Bake

  1. Cook the Veggies: We’ll quickly steam our cauliflower and broccoli, then sauté them with some onion and garlic tossed in delicious garlic-flavored olive oil.
  2. Make the Cheese Sauce: In the meantime, we’ll whip up a simple lightened-up cheese sauce. I found this recipe gem in an old Weight Watchers cookbook, and I’ve been hooked ever since. It’s just evaporated milk, shredded cheddar, and a touch of cornstarch.
  3. Pro Tip: Keep your flame low while making the sauce. High heat makes the sauce grainy, especially with reduced-fat cheeses. Nobody wants grainy cheese sauce, am I right?
  4. Combine and Bake: Next, we’ll marry our sautéed veggies and glorious cheese sauce, then slide it into the oven. Around 20 minutes later, you’ll be face-to-face with a hot, bubbly, and insanely delicious cheesy cauliflower bake.

Recipe Tips And Variations

  • Using Frozen Veggies: Yes, you can use frozen cauliflower and broccoli florets, but cook them according to the instructions on the package and drain any excess liquid before combining the veggies with the cheese sauce.
  • Vegetable Alternatives: You can swap out the cauliflower for another veggie. Any vegetable that’s been lightly roasted, given a quick steam, or even blanched would be a great fit. Try Brussels sprouts, green beans, or more broccoli.
  • Cheese Sauce: Remember to keep the heat low when you’re making the cheese sauce to avoid a grainy texture. Stir continuously for a smooth, creamy sauce.
  • Switch up the Cheese: Feel free to play around with the types of cheese in this dish. A blend of cheddar and gruyere or a sprinkle of parmesan can add a different twist to your casserole.
  • Add-ins: Add some protein like cooked chicken, bacon, or even canned tuna.
  • Seasoning: Don’t forget to season your veggies during the sautéing phase. A little salt and pepper can make a huge difference in the overall flavor of the dish.

How To Store & Freeze

  • To Store: Transfer leftovers to an airtight container and keep in the fridge for 2 to 3 days or in the freezer for 2 to 3 months.
  • To Reheat from Frozen: Place it in your microwave on high for around 3 to 4 minutes. The exact time might vary based on your microwave’s power. Let it sit briefly after you take it out.

    Can this be cooked and then frozen?

    1. Katerina Petrovska says:

      Technically, you can freeze just about anything, including this, but just keep in mind that the texture will change and become noticeably grainier when you reheat it.

  2. Marilyn says:

    Can this be frozen after cooking the casserole?

  3. Cheryl Wood says:

    ThankYou for this recipe! Used cream cheese instead of making sauce but used seasonings. Very Good!

    1. Katerina Petrovska says:

      That’s great! I’m very glad you enjoyed it! Thank YOU! 🙂

  4. Mish says:

    Its one of the best recipes without too many calories, especially since I don’t keep cream or cheese on hand. We are trying to eat healthy and this dish is yum on so many levels! Thank you for sharing!

    1. Mish says:

      Forgot to mention. I skipped the cheese and made a white sauce with olive oil and flour. Then added lite milk. Turned out thick and delish. Coated the cauliflower broc with it and baked with panko crumb on top. Yummalicious!

    2. Katerina Petrovska says:

      I’m very glad you enjoyed it! Thank YOU! 🙂

  5. Jessica says:

    This looks delicious!! Does it freeze well? I always make a cauliflower bake as a side for Christmas dinner but I’m looking for a new recipe and I’m hoping to be able to make it ahead of time and heat it up in the oven before serving. I don’t want it to end up watery from freezing :/ *fingers crossed*

  6. Nirmala Boodoo says:

    Will try for sure tomorrow morning. Sounds delicious!

    1. Katerina Petrovska says:

      I hope you enjoy it! Thank YOU! 🙂

  7. Terry Stenson says:

    I just made this recipe and OMG! this was so easy, and so very good. I added chicken to the mix, outside of that I kept it the same. I have been on Keto for a year now and am always looking for complete meals. That’s why I added the chicken. The sauce was a great idea thanks for finding it on ww. Thank-you for this recipe and many others I’ve bookmarked as well.

    1. Katerina Petrovska says:

      That’s great! I am very glad you enjoyed it! Thank YOU! 🙂

  8. Laura says:

    I love this dish but my daughter will not be able to have any oil or butter in cooking or baking once she has bariatric surgery. She is preparing for it now. Anyway to get that taste without the oil?

  9. Effie says:

    Everyone LOVED it!!!
    I replaced the evaporated milk with cream cheese (sounded better and it was!) and didn’t use the corn starch (seemed unnecessary).

    It was absolutely divine!!
    Thank you 😊

    I LOVE this dish, so flavourful. Served it to friends who all loved it too. I made it exactly as in the recipe and I did not miss the extra fat at all.
