The recipe was inspired by my Cauliflower pasta recipe. I updated it with pesto sauce and crispy cauliflower.

Cauliflower Pasta
My family love roasted cauliflower. The entire tray usually disappears in minutes. And we are addicted to pasta. So I decided to make a main dish and get the best of both worlds. Lemony and garlicky cauliflower florets are roasted to perfection and then served with flavorful pesto pasta. It is a real flavor bomb! And it is what we need for cold and nasty days.
Lemon juice provides an amazing zesty flavor and homemade pesto gives freshness and a great texture. I added a jalapeno, but you can leave it out.

Cauliflower Pasta ingredients
- Cauliflower- I used a large head of cauliflower for this recipe. Cut into florets, season and bake.
- Olive oil- Use olive oil or melted unsalted butter.
- Paprika- Adds a vibrant color and sweet pepper flavor to the cauliflower.
- Black pepper
- Garlic cloves- Chop or mince garlic. Gives a fantastic garlicky flavor.
- Lemon juice- Gives a great zesty flavor.
- Pasta- You can use any shape of pasta, but fusilli or rotini are the best options because they have curves that help pesto to stick well.
- Pesto- I provided the recipe for homemade pesto. But a store bought will work well. Substitute the homemade pesto with ¾ -1 cup of store–bought pesto.

You can make pesto at home for a fraction of the cost. Use any fresh herbs (parsley, cilantro, basil or a combination) or spinach, any nuts, jalapeno, lemon juice, virgin oil and Parmesan cheese. For vegan cauliflower pasta substitute Parmesan with nutritional yeast.
Simply combine all the ingredients in a food processor and pulse until well blended but not smooth. It should have some texture. The whole process takes not more than 5 minutes.

How to Roast Cauliflower
- Prepare a large baking sheet. Line it with parchment paper (make sure your parchment paper can tolerate 425 F (220 C) oven heat) or foil. Alternatively you can grease it with a cooking spray.
- Toss. Combine the olive oil, paprika garlic and lemon in a small bowl. Put cauliflower florets on the tray, season with salt and pepper and pour the mixture. Toss to coat evenly.
- Roast at 425 F ( 220 C) until tender and with crispy edges.

How to Make Cauliflower Pasta
- Roast Cauliflower: Roast for 20 minutes at 425 F (220 C) or until tender.
- Make pesto: Save money and make the healthy and easy pesto at home.
- Cook Pasta: Bring a large pot of salted water to a boil and cook pasta according to package instructions. I recommend to reserve some water from pasta before draining. You might need it to thin it out. Drain the pasta and return to the pot. Combine with pesto. Add the roasted cauliflower and mix.
