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.

  • 1 pound broccoli florets
  • 1 pound cauliflower florets
  • 3 tablespoons garlic flavored olive oil, divided, you can also use regular olive oil
  • 1 large yellow onion, thinly sliced
  • 2 cloves garlic, minced
  • salt and fresh ground black pepper, to taste
  • 1 cup reduced-fat shredded cheddar cheese, divided
  • 1 tablespoon cornstarch
  • 1 can (12 ounces) fat free evaporated milk
  • ½ teaspoon dijon mustard
  • ¼ to ½ teaspoon smoked paprika, or to taste
  • ¼ cup low fat part skim shredded mozzarella cheese


  • Preheat oven to 400˚F. Drizzle a little olive oil on the bottom of a square baking dish; spread it around and set aside.
  • In a large skillet, bring 1/2 inch of salted water to a boil. Add the broccoli and cauliflower; cover and cook over high heat until crisp-tender, about 4 minutes. Drain the vegetables in a colander and set aside.
  • Wipe out the skillet, add 2 tablespoons olive oil, and heat over medium-high heat. Add onions and cook for 2 to 3 minutes or until softened.
  • Stir in the minced garlic and continue to stir and cook for 1 minute. Add broccoli and cauliflower to the skillet. Season with salt and pepper and continue to cook for about 2 minutes, or until lightly golden.
  • Remove from heat and transfer the vegetables to the baking dish; set aside.
  • Wipe the skillet and add 1 tablespoon olive oil, 3/4 cup shredded cheddar cheese, cornstarch, evaporated milk, mustard, salt, pepper, and paprika.
  • Cook over low heat, stirring constantly with a whisk, until melted and thickened, about 2 minutes.
  • Pour the cheese sauce over the broccoli and cauliflower; stir to combine. Sprinkle the remaining cheeses over the top.
  • Bake for 20 minutes or until lightly browned and bubbly.
  • Remove from oven and let stand 5 to 8 minutes, then serve.



  • This casserole can be assembled up to one day in advance, then baked just before serving.
  • Swap out the cauliflower for another veggie. Brussels sprouts and green beans will work.
  • Aim for crunchy, not soggy, veggies in the first steaming step.
  • For a velvety cheese sauce, keep your heat low and keep stirring.
  • Mix up your cheese game – consider a mix of cheddar and gruyere or a dash of parmesan.
  • Want to make it a main course? Throw in some cooked chicken, crispy bacon, or even canned tuna.
  • Don’t forget to season your veggies when frying them.

  1. P.S. I appreciate all the details you provided in the recipe. I am not a very experienced cook, and for me, those are the things that can make a big difference in the success or failure of a dish.

    1. Yes, you can. Keep it covered in the fridge, then take it out when ready to bake. Take it out of the refrigerator about 20 minutes before baking if time permits.

  2. Love! Love! Love this recipe! It’s a lot of steps but worth it! It was the best recipe to highlight broccoli and cauliflower and cheese!! Sooooo! Good! And worth all the steps! Will make for Thanksgiving!!

      1. I wonder if mustard is bottled? Dont think ive seen dry dijon…so thinking so. A LOT of recipes have mustard but never seem to say. Would like to try tonight. Broccoli , cauliflower & cheese….has to be a hit !! TYVM

  3. I wanted a recipe, not a bloody novel.
    What the he’ll is a pound?
    Why would you put milk in a can, we have cows in Australia.
    Is everything in the US Processed?
    We know that MacDonald’s tastes like cardboard on cake.

    1. If you cant say anything nice…….zip it.16oz.. We have cows in US too.(evap not reg milk) No everything is not processed. Dont go to McD’s then. My goodness Tess….Hope you have a better day !!!

  4. Awsome cooked chicken drumsticks as a side dish and sprinkled cheese on top with chilli
    Will be making this one again for sure

      1. Made this tonight and my husband, who is usually a meat and potatoes guy, loved it! He ate two helpings and asked me to please not lose the recipe. 😊 My grandson even ate it, and it’s hard to get him to eat his vegetables! Thank you for this delicious recipe!

    I always have these ingredients on hand and will be giving this a try! Yes and I can eat broccoli/cauliflower every day♥Thanks for sharing!

      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.

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

  7. 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. 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!

  8. 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*

    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.

  10. 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?

  11. 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.

  13. I’m planning on making this for Thanksgiving Day. Can I prep it tonight but bake and serve tomorrow??

      Hi! Yes, prepare the veggies, but don’t make the cheese sauce until you are ready to pop it in the oven.
