Before you start

Before you begin, gather all necessary ingredients and preheat your oven to ensure it reaches the correct temperature. Dice your red onion into uniform pieces to ensure they cook evenly alongside the roasted peppers. Have your large pot ready for the pasta and ensure you have a colander nearby for draining.

Preparing your workspace by clearing clutter and having all items within reach will make the cooking process smooth and efficient. Remember to check that your baking dish is clean and ready for the oven before you start the roasting phase.

Ingredients at a glance (8)
  • 150 g garlic and herb Boursin cheese
  • 300 g roasted red bell peppers, sliced
  • 1 red onion, diced
  • 60 ml olive oil
  • 350 g cavatappi pasta
  • 80 ml starchy pasta water
  • fresh parsley, for serving
  • chili flakes, for serving

Instructions

Preparation and roasting

  1. Prepare the baking dish
    Preheat your oven to 400°F (200°C). In a ceramic baking dish, place the wheel of garlic and herb Boursin cheese in the center. Arrange the sliced roasted red bell peppers and diced red onion around the cheese. Drizzle everything with the olive oil to ensure even coating.
    Look for The oven is fully preheated and the cheese is centered in the dish surrounded by vegetables.
    Tip Ensure the baking dish is large enough to hold the vegetables comfortably without overcrowding.

At the end of this phase, the baking dish is ready for the oven. The Boursin is positioned in the center, surrounded by the peppers and onions, with a drizzle of olive oil ensuring everything is ready to roast.

The aroma of the cheese and peppers will begin to fill the kitchen as the oven does the hard work of softening the ingredients.

Baking the sauce

  1. Bake the sauce base
    Place the baking dish into the preheated oven and bake for 25 minutes. Watch for the edges of the peppers and onions to become tender and slightly caramelized, while the Boursin cheese softens and begins to bubble gently at the edges.
    Look for The cheese is soft and the vegetables are tender with bubbling edges.
    Tip Do not over-bake, as the cheese should remain creamy rather than becoming dry.

After 25 minutes, the sauce base is ready. The cheese should be soft and creamy, and the red peppers and onions should be tender, with their edges slightly browned and caramelized. The mixture will look bubbly and fragrant, signaling that it is time to combine it with the cooked pasta for the final step of the recipe.

Combining and finishing

  1. Combine and serve
    While the sauce bakes, cook the cavatappi pasta in a large pot of boiling salted water until al dente. Reserve 80 ml of the starchy pasta water before draining. Remove the baking dish from the oven and stir the melted cheese and roasted vegetables together until smooth. Add the cooked pasta and the reserved pasta water, tossing until the sauce coats every spiral. Garnish with fresh parsley and chili flakes before serving.
    Look for The sauce is velvety and coats the pasta, with a consistent texture throughout.
    Tip The reserved starchy water is essential for emulsifying the sauce into a smooth, silky consistency.

The final result is a vibrant, creamy pasta dish where every piece of cavatappi is coated in the velvety sauce. The fresh parsley and chili flakes should be clearly visible on top, adding a pop of color and a subtle heat. The dish should smell rich, herbal, and deeply savory, ready to be served immediately while hot and fresh.

Common mistakes

One common mistake is failing to reserve the pasta water, which is crucial for achieving the right sauce texture. Without the starchy water, the sauce may become too thick or fail to bind properly to the pasta.

Another mistake is using the wrong type of pasta; long, smooth noodles like spaghetti do not hold this type of sauce well. Ensure you use a shaped pasta that can catch the sauce. Finally, avoid over-baking the cheese, as it can separate and become oily if left in the oven for too long.

How to tell it’s done

The dish is done when the Boursin cheese has completely melted into the roasted peppers, creating a smooth and creamy sauce. The vegetables should be tender and lightly caramelized at the edges. When you toss the cooked pasta with the sauce, it should coat the spirals evenly, resulting in a glossy, uniform appearance.

The sauce should be thick enough to cling to the pasta, not watery or separated. If the sauce seems too thick, add an extra splash of reserved pasta water to loosen it to your desired consistency.
