Pasta with Roasted Cauliflower

This pasta with roasted cauliflower is the fanciest pasta dish I ever made for myself but it is surprisingly low key at the same time. I was trying to think up some winter recipes to test, and so I thought about what type of food is in season. A lot of root veggie soups come to mind, but also the flavors of citrus and cooler weather crops like cauliflower. I have been loving lemon on pasta lately, and I love the nuttiness of roasted cauliflower is so delicious. I’ve also made this dish with some toasted pine nuts on top on days when I have a bit more time. It all goes together so great!

Why did I make this dish?

Truthfully, I have never been a big pasta eater, but my daughter and wife love it. Noodles, especially spaghetti are easy for my daughter to eat and she loves the tastes of lemon and parmesan. As for the cauliflower, sometimes she eats it and sometimes she doesn’t, but I always serve it to her. My wife was ecstatic to hear that we were eating pasta that night. Pasta is her comfort food. She grew up eating butter and noodles, and this dish is not very far off from that.

How do you roast Cauliflower?

I like to break up my cauliflower florets into bite size pieces, toss with a little olive oil, add some spices. I usually choose salt, pepper, and garlic powder. Then I put it on a baking sheet with parchment paper and into a preheated oven at 400F for 25 mins or until each piece has a nice char on it. The roasting gives cauliflower the most delicious nutty flavor. It’s honestly my favorite vegetable for the past decade.

Servings 4 People


  • 12 oz Cauliflower Florets
  • 1 tbsp Olive Oil
  • 1/4 tsp Sea Salt
  • 1/2 tsp Garlic Powder
  • A few Pinches Black Pepper
  • 8 oz Spaghetti
  • 2 tsp Minced Garlic
  • 2 tbsp butter
  • 1 Large Lemon Juiced
  • 1/4 cup Water or broth
  • 1 cup Half and Half
  • 1/3 cup Grated Parmesan Or more!
  • 3/4 tbsp Flour arrowroot or tapioca flour also work


  • Preheat oven to 400F
  • Place cauliflower florets on a parchment paper lined baking sheet, drizzle with oil, and add spices. Massage the oil and spices into the cauliflower and then bake for 20-25 minutes or until cauliflower has one side roasted dark
  • While the cauliflower is roasting, boil your pasta and start your sauce.
  • Once pasta is done boiling, drain it and set it aside.
  • To make the sauce, heat the butter on medium heat and add the minced garlic.
  • Once the butter and garlic start to sizzle, add the half and half. Bring to a low boil and add the flour. This step is really important. If you don’t add flour, you run the risk of the half and half curdeling when you add your lemon juice. Mix well, and lower the heat to medium low.
  • Once sauce starts to thicken, add in the lemon juice, water, and parmesan cheese. Mix well. You will see that the sauce is a little thicker now.
  • Turn off the heat, add your pasta and roasted cauliflower and mix.
  • Enjoy!

    Cauliflower grew on me and I really enjoy it now. I also like the cauliflower pizza crusts. Question: how much of those pizza crusts are typically cauliflower vs other ingredients?
