Perfectly Roasted Vegetables

Knowing how to roast all vegetables perfectly is definitely a learned skill. All veggies are different and they all have vast cooking times.

The most common rule of thumb is to roast thicker vegetables at a higher temperature because they can handle the heat. For example, potatoes or sweet potatoes can roast at a higher temp because of their thickness. Broccoli, on the other hand, lends well to a lower heat when cut into florets.

The other common rule when roasting is to use lots of olive oil and a rimmed baking sheet. The oil flavors the veggies and prevents them from sticking to the pan. You can also use a heavy pinch of salt and pepper for perfectly seasoned vegetables.

How to Make Creamy Garlic Butter Pasta w/ Roasted Cauliflower

To Roast the Cauliflower:

Preheat your oven to 400 degrees Fahrenheit and line your baking sheet with parchment paper.

NOTE: Doing this step is a MUST to prevent sticking.

In a bowl, add the chopped cauliflower, olive oil, cajun seasoning, garlic powder, cumin, parsley, and smoked paprika together and stir until cauliflower is coated.
Add coated cauliflower until prepared baking sheet, spreading out evenly in a single layer, and bake for 20-25 or until golden brown and crisp.

To Boil the Pasta:

Cook pasta according to packaging. NOTE: rigatoni pasta doesn’t take a long time to cook, usually 8-10 minutes (however, you should cook at 6-8 minutes or so—‘al dente’).

To Make the Sauce:

Over medium-high heat, melt 3 tablespoons of unsalted butter in a 12-inch skillet.

Add the olive oil and minced garlic, sautéing until fragrant and translucent. Add in the cajun seasoning (if desired) and parsley and stir together until combined. 

Slowly pour in the heavy cream, stock, stirring frequently until incorporated. Add the grated cheese until combined and sauce begins to bubble, about 3-4 minutes. Add in the cooked pasta and stir until pasta is well coated.

Remove from heat and serve with grated mozzarella (if desired) and topped with the roasted cauliflower.

Bon Appetit!

Tips & Tricks

  • STORAGE: Any leftovers can be kept in a tightly sealed container and refrigerated for up to 3-4 days.
  • GLUTEN-FREE: To make this dish GF, simply use Gluten-Free pasta and ensure that other ingredients are GF-friendly. 
  • PASTA: You can use long pastas like Pappardelle, Fettuccine, etc. if desired, however, I would recommend tossing with tongs to ensure that pasta is fully manageable and fully coated. Otherwise, the traditional rigatoni pasta works perfectly!
  • VEGGIES: If preferred, you can always add in greens to the mix for additional flavor such as Kale, Spinach or Collard Greens.
  • CAJUN SEASONING (STORAGE): Any leftover cajun seasoning mix can be stored in a ziplock bag for later use or used as garnish. For homemade cajun seasoning, head over to my One-Pot Cajun Pasta recipe.
