Truffle Four Cheese Mac with Crispy Panko Cauliflower Step-by-step instructions

Before you start

Before starting, gather all ingredients and equipment. Preheat the oven to 425°F (220°C) for roasting the cauliflower. Bring a large pot of salted water to a boil for the pasta.

Grate the cheeses and slice the chives, keeping them separate. Have the cast iron skillet ready, as it will be used for the sauce and then moved to the broiler.

Instructions

Roast and Prep

1. 1Prepare the cauliflower and pasta
   Heat the oven to 425°F (220°C). Cut the cauliflower into bite-sized florets and place them on a baking sheet. Drizzle with olive oil, sprinkle with salt and black pepper, and toss to coat. Roast for 20-25 minutes, until golden and tender. Meanwhile, bring a large pot of salted water to a boil and cook the cavatappi according to package directions until al dente. Drain and set aside.
   Look for The cauliflower should be browned at the edges and easily pierced with a fork.
   Tip Cut the florets into similar sizes so they roast evenly.
2. 2Grate the cheeses and slice the chives
   Grate the gruyere and sharp cheddar on the large holes of a box grater. Grate the parmesan on the fine holes. Shred the mozzarella. Slice the chives into thin rounds. Set all aside.
   Look for You should have about 3 cups of shredded cheese total.
   Tip Shredding your own cheese melts more smoothly than pre-shredded.

The cauliflower should be fork-tender and golden at the edges. The pasta is cooked al dente and drained. Cheeses are shredded and chives sliced, ready to go. Take a moment to check the color, texture and aroma before you move on to the next step.

Make the Sauce and Combine

3. 3Make the truffle cheese sauce
   In a large cast iron skillet, melt the butter over medium heat. Whisk in the flour and cook for 1 minute. Gradually whisk in the milk, stirring constantly, until smooth. Bring to a simmer and cook until thickened, about 3-4 minutes. Remove from heat and stir in the truffle oil, then add the gruyere, cheddar, parmesan, and mozzarella. Stir until the cheese is melted and the sauce is smooth.
   Look for The sauce should coat the back of a spoon and be glossy.
   Tip Keep the heat low to prevent the sauce from separating.
4. 4Combine pasta and cauliflower with sauce
   Add the cooked cavatappi and roasted cauliflower to the skillet with the cheese sauce. Gently fold everything together until the pasta and cauliflower are evenly coated with the sauce.
   Look for Everything should be well coated with the creamy sauce.
   Tip Fold gently to keep the cauliflower florets intact.
5. 5Top with cheese and panko
   Sprinkle the remaining shredded cheese (if any) over the top, then evenly sprinkle the panko breadcrumbs over the entire surface.
   Look for The top should be fully covered with panko.
   Tip For extra crunch, toss the panko with a little melted butter first.

The cheese sauce is smooth and coats the back of a spoon. The pasta and cauliflower are evenly coated. The top is covered with cheese and panko, ready for broiling.

Broil and Serve

6. 6Broil until golden
   Turn the oven to broil. Place the skillet under the broiler and cook for 2-4 minutes, until the panko is golden brown and the cheese is bubbly. Watch closely to prevent burning.
   Look for The top should be deep golden brown and the sauce bubbling at the edges.
   Tip Broilers vary, so check every minute.
7. 7Garnish and serve
   Remove the skillet from the oven and let it cool for a few minutes. Sprinkle the sliced chives and any toasted panko crumbs over the top. Serve hot, pulling a portion with a spoon to show the cheesy stretch.
   Look for The chives add a fresh green contrast to the golden crust.
   Tip Letting it rest a few minutes makes serving easier.

The panko is golden brown and the cheese is bubbling. The chives add a fresh garnish. The dish is served hot with a satisfying cheese pull. Take a moment to check the color, texture and aroma before you move on to the next step.

Common mistakes

One common mistake is overcooking the pasta, which can become mushy when baked. Cook it al dente, as it will continue to cook in the sauce. Another is not watching the broiler closely—panko can burn quickly.

Also, avoid using low-fat milk, as it may not produce a creamy sauce. Finally, be sure to whisk the sauce constantly when adding the milk to prevent lumps.

How to tell it’s done

The dish is done when the top is golden brown and the sauce is bubbling around the edges.

The internal temperature of the casserole should be at least 165°F (74°C) if you want to check, but since there are no raw proteins, the visual cues are most important.

Let it rest for a few minutes before serving to allow the sauce to set slightly.
