Ingredients

Here are all the ingredients you’ll need to make Crispy Roasted Cauliflower with Creamy Pesto Pasta:

For the Cauliflower

  • 1 large head of cauliflower, cut into florets
  • 1/2 cup extra virgin olive oil
  • 2 teaspoons smoked paprika
  • 1/2 teaspoon red pepper flakes
  • 1 pinch kosher salt and black pepper
  • 3-4 cloves garlic, finely chopped or grated
  • 1 tablespoon lemon zest, plus 2 tablespoons lemon juice

For the Pasta

  • 1 pound pasta, any variety

For the Pesto

  • 1 1/2 cups fresh basil
  • 1 cup baby arugula, spinach, or a mix
  • 1 jalapeño, seeded (if desired)
  • 1/4 cup toasted nuts, such as pine nuts, walnuts, or pistachios
  • 1/3 cup grated parmesan cheese or nutritional yeast
  • 1/4-1/3 cup canned full fat coconut milk (or cream/milk of choice)

How to Make Crispy Roasted Cauliflower with Creamy Pesto Pasta

Step 1: Preheat the Oven

Preheat your oven to 425° F.

Step 2: Prepare the Cauliflower

On a baking sheet, combine the cauliflower florets, 1/4 cup olive oil, smoked paprika, red pepper flakes, and a pinch each of kosher salt and black pepper. Toss well to ensure everything is evenly coated.

Step 3: Roast the Cauliflower

Transfer the baking sheet to the oven. Roast for 20 minutes until tender. After this time, add in 2 cloves of garlic and lemon zest. Roast for an additional 10 minutes until charred.

Step 4: Make the Pesto

While the cauliflower roasts, prepare your pesto. In a blender or food processor, combine fresh basil, arugula/spinach, jalapeño (if using), 1-2 cloves garlic, lemon juice, toasted nuts, parmesan cheese (or nutritional yeast), and remaining olive oil. Season with salt to taste. Pulse until smooth, adding water if needed to thin it out.

Step 5: Cook the Pasta

Bring a large pot of salted water to a boil. Add your pasta and cook according to package directions until al dente. Just before draining, reserve about 1/2 cup of pasta cooking water. Drain the pasta but return it back to the hot pot.

Step 6: Combine Everything

To the hot pasta, add in your prepared pesto along with coconut milk. Toss everything together until well combined. If needed, use reserved pasta cooking water to achieve desired creaminess.

Step 7: Serve

Divide your creamy pesto pasta among bowls. Serve each bowl alongside roasted cauliflower. Top with herbs and greens as desired. Enjoy every bite!

How to Perfect Crispy Roasted Cauliflower with Creamy Pesto Pasta

Perfecting this dish can elevate its taste and texture. Here are some tips to make sure your meal turns out wonderfully every time.

  • Choose Fresh Ingredients: Using fresh basil, arugula, and high-quality olive oil will significantly enhance the flavor of your pesto.
  • Roast Until Golden: Ensure the cauliflower is roasted until golden brown and crisp. This adds depth and texture to your dish.
  • Adjust Seasoning: Don’t hesitate to taste and adjust seasoning as needed. Adding more salt or lemon juice can brighten up the dish remarkably.
  • Reserve Pasta Water: Always save some pasta cooking water before draining. This starchy water helps bind the sauce to the pasta.
  • Experiment with Nuts: Try different types of nuts in your pesto, such as walnuts or pistachios, for varied flavors and textures.
  • Let It Rest: Allowing the dish to rest for a few minutes after combining ingredients lets flavors meld beautifully before serving.

Best Side Dishes for Crispy Roasted Cauliflower with Creamy Pesto Pasta

Pairing side dishes with your Crispy Roasted Cauliflower with Creamy Pesto Pasta can enhance your meal’s overall appeal. Here are some excellent options:

  1. Garlic Bread: A classic choice that complements creamy pasta perfectly. Opt for crusty bread slathered in garlic herb butter before baking.
  2. Grilled Vegetables: Seasonal vegetables like zucchini, bell peppers, or asparagus add color and nutrition alongside your main dish.
  3. Caprese Salad: Fresh tomatoes, basil, and mozzarella drizzled with balsamic glaze provide a refreshing contrast to the richness of the pasta.
  4. Roasted Brussels Sprouts: Caramelized Brussels sprouts seasoned with olive oil deliver earthy flavors that pair nicely with creamy sauces.
  5. Quinoa Salad: A light quinoa salad loaded with cucumbers, cherry tomatoes, and parsley offers a healthy balance to your hearty pasta dish.
  6. Steamed Broccoli: Simple steamed broccoli adds a nutritious touch while providing bright green color on your plate; drizzle with olive oil for added flavor.
  7. Cucumber Raita: A cooling yogurt-based dip made with cucumber offers a refreshing element that contrasts well with spicy notes in the pasta.
  8. Mixed Green Salad: A simple salad dressed lightly in vinaigrette enhances freshness without overpowering the main flavors of the meal.

Common Mistakes to Avoid

When making Crispy Roasted Cauliflower with Creamy Pesto Pasta, it’s easy to overlook a few key details. Here are some common mistakes to avoid:

  • Not Preheating the Oven: Failing to preheat your oven can lead to uneven cooking. Always ensure your oven reaches 425° F before roasting the cauliflower for the best results.
  • Overcooking the Cauliflower: Cooking the cauliflower too long may result in mushy florets. Keep an eye on it and aim for tender yet firm pieces after about 30 minutes of roasting.
  • Forget to Reserve Pasta Water: Skipping the step of saving pasta water can make your dish dry. Remember, this starchy water helps create a creamy sauce that clings beautifully to the pasta.
  • Using Old Ingredients: Using stale nuts or wilted greens in your pesto can affect flavor. Always check for freshness, especially with herbs and nuts, for the best taste.
  • Skipping Seasoning: Neglecting to season adequately can make your dish bland. Taste as you go and adjust salt, pepper, and lemon juice for a balanced flavor profile.

Storage & Reheating Instructions

Refrigerator Storage

  • Store leftovers in an airtight container.
  • Best consumed within 3-4 days for optimal freshness.
  • Keep roasted cauliflower separate from pasta if possible to maintain texture.

Freezing Crispy Roasted Cauliflower with Creamy Pesto Pasta

  • Place in a freezer-safe container or bag.
  • Can be frozen for up to 2 months.
  • Thaw overnight in the refrigerator before reheating.

Reheating Crispy Roasted Cauliflower with Creamy Pesto Pasta

  • Microwave: Use a microwave-safe dish, cover loosely, and heat in 1-minute intervals until warmed through.
  • Stovetop: Add a splash of water or olive oil in a pan over medium heat, stirring until heated evenly.
