Servings: 4 people


  • 8 ounces whole-wheat pasta reserve 1/2 cup of the cooking water
  • 1 head cauliflower
  • 4 cloves garlic minced
  • 2 tablespoons olive oil
  • 1/2 teaspoon thyme dried
  • 1/4 teaspoon pepper
  • 1/2 lemon juiced
  • 1/2 cup walnuts chopped
  • 1/2 cup parmesan cheese grated
  • 1/4 cup heavy cream
  • 1/4 teaspoon salt
  • parsley Italian, chopped (optional garnish)


  • Preheat oven to 450 degrees F. Boil noodles according to package directions and drain while reserving 1/2 cup of the cooking water.
  • Chop cauliflower into 1 - 2 inch florets (discarding large stems). Toss on a baking sheet with garlic, olive oil, thyme, pepper, and lemon juice. Bake until the cauliflower just begins to turn brown and is easily pierced with a fork, about 20 - 22 minutes, stirring once or twice.
  • To toast the walnuts, add them to the baking sheet with the cauliflower and put it all back in the oven for 2 - 3 minutes while keeping a close eye on it because they can go from brown to burnt very quickly!
  • Meanwhile, toss the noodles with the reserved cooking water, Parmesan cheese, heavy cream, and salt. Stir in the cauliflower mixture and heat on medium-low until the sauce thickens. Divide among pasta bowls, garnish with parsley if desired, and serve warm.

  1. Do you think there is a way to do it nut-free for allergies in our home or should we skip this one and the walnuts are imperative? Thanks! Love your recipes and cookbooks!!

    1. Hi Sarah, while the toasted walnuts definitely add to the flavor and texture, you can omit if needed. We’d love to hear how it turns out for you. – Nicole

    My 9-year old daughter claims she hates cauliflower (despite us having quite often). When she saw me making this for dinner she asked “Why are you ruining pasta by putting cauliflower in it?” Silly girl then asked for seconds once she tried it! This will be one of our go to meals. All 4 of us loved it!

    I made this tonight for dinner and it was delicious!! Super easy and even my kids ate the noodles (minus the cauliflower with other veggies on the side =). Will definitely be making again!

    I’ve made so many really yummy recipes from this site but this is not one of them. I followed the recipe but there was not near enough sauce for the pasta and it never got thick. The lemon on the cauliflower didn’t taste good at all. Thankfully I made an awesome salad so my family didn’t go hungry…

    Since this recipe has been posted I’ve made it multiple times–my husband and I love it! We originally roasted the cauliflower in the oven like the recipe states, but for us, it ended up being easier to cook it in the skillet and we haven’t noticed any difference in flavor. This is a weekly dinner staple now!

  6. I really like this idea. I want to use that skinny Chinese pasta instead of the ordinary one. The skinny pasta tend to soak the flavours from the sauce better… Or at least that’s my opinion.

  7. This sounds like a great recipe! I am also non dairy and non gluten. I will try this with Almond milk in place of heavy cream. Any suggestions for the Parmesan substitution (all-natural of course)?
    Also, I have been buying non-gluten alternatives to pasta…
    Isn’t pasta in general (whether it’s regular pasta or gluten-free pasta) a processed food? My goal is to avoid preservatives and be as all-natural as possible.
    Thanks for your help! I am really enjoying your blog and recipes!

    1. Yes, even if you make it yourself, all pasta is technically processed. However, unless you are gluten free there is nothing wrong with minimally processed wheat pasta. Just make sure you buy WHOLE wheat pasta. Bella Terra, Trader Joe’s and DeLallo all make 1 ingredient organic whole wheat pastas. The 1 ingredient is organic durum whole wheat. I buy different brands depending on which shape I need.

      Hi there. While it doesn’t really stand up to the rules, nutritional yeast is often used like Parmesan. Regarding pasta, we consider it minimally processed and gets a pass as long as it is whole grain or for the gluten free among us, give a bean, lentil , or brown rice pasta a try.

  8. My husband swore he hated cauliflower until he tried it roasted. Now he sneaks into the kitchen as I’m pulling it from the oven to “taste” it. We haven’t tried it over pasta – what a good idea.

  9. This looks delicious but I rarely have heavy cream on hand because it always goes bad since i only ever use a tiny amount. Do you think I could get a similar result with either 2% milk or almond milk since I usually keep those around? I’m excited to try this recipe!

    1. Amy Taylor (comment moderator)

      Hi Jessica. As a general rule, I’ve had better luck when subbing real coconut milk/cream for heavy cream as the consistency is similar.

  10. This would be such an easy weeknight meal– looks delicious, too. Roasted cauliflower really is the best. For anyone who thinks they don’t like cauliflower– try it roasted! Love the addition of the walnuts for a little boost of omega 3s and protein.
