This recipe is part of our complete guide to oil-based Italian sauces.

This is the kind of dish that impresses at a dinner party but comes together with a straightforward technique once you know the method. Read on and we'll walk you through every step.

Celebrating Cauliflower

For the last decade, it feels like everyone has been transforming cauliflower into something it isn't — cauliflower rice, pizza crust, you name it. No shade to those recipes. Getting your vegetables while eating cheese and tomato sauce is a mission we fully support.

But cauliflower deserves its main character moment again. The best way to give it that? Feature it as the star ingredient in a rich, savory pasta sauce. When you blend it with olive oil, garlic, and Pecorino Romano, the result is silky, deeply flavored, and genuinely impressive.

Why Cauliflower Makes Such a Great Cheese Sauce

Cauliflower is one of the most versatile vegetables you can cook with. It roasts beautifully, boils evenly, and blends into an incredibly smooth base. That texture is exactly what makes it such a great foundation for a cheesy pasta sauce.

The key is blending — not mashing. Once the cauliflower is fully cooked through, an immersion blender or standard blender turns it completely smooth. From there, you stir in freshly grated Pecorino Romano over low heat until everything melts together into a velvety sauce. It comes together faster than you might expect.

Can I Make This Cheese Sauce with Broccoli?

Yes, absolutely. Broccoli has a stronger, earthier flavor than cauliflower, so just keep that in mind when seasoning. If you want to try it, we also have a great one-pot broccoli pasta to inspire you.

How to Make Garganelli Fresh Pasta

The most time-intensive part of this recipe is the fresh pasta. Garganelli is a rolled, ridged shape made from egg dough — similar to penne but with a more delicate texture. We used a recipe from our friends at q.b. Cucina, who specialize in fresh pasta shapes and have a lot of experience working with dough.

Can I Use Dried Pasta Instead?

Absolutely. If you find yourself short on time or patience, dried pasta works well with this sauce. That said, fresh pasta really does take this dish to another level. The texture is softer, silkier, and it holds the cauliflower cheese sauce beautifully.

Fresh pasta dough is also much more forgiving than you might think. Unlike pie crust, you can work it as long as you need to — the more you knead it, the better it turns out. If a shape doesn't come together right, just reform the dough, let it rest in the fridge for 30 minutes, and try again. It genuinely gets easier each time.

Choosing a Vegetable Broth

This recipe doesn't call for a specific store-bought broth. You can use bouillon cubes, broth powder, or your favorite boxed vegetable stock. If you want to go from scratch, a simple broth with 2 carrots, half an onion, and a few stalks of celery does the job perfectly.

Reserve about half the broth before blending. If the sauce turns out too thick after the cauliflower is blended, you can stir in the reserved broth a little at a time to reach the right consistency.

How to Make Cauliflower Cheese Sauce

Start by roughly chopping the cauliflower into florets or large chunks. Bring your vegetable broth to a boil, add the cauliflower, and cook until fork-tender. Some of the broth will reduce during this process — that's a good thing, because it helps thicken the sauce.

While the cauliflower cooks, heat a pan over medium-low and add the extra virgin olive oil and garlic. Smash the garlic cloves first so the oil gets into all the crevices. Gently fry the garlic for just one to two minutes until it turns a light blonde color. Don't rush this step — high heat will burn the garlic before it softens.

Transfer the cooked cauliflower, broth, garlic, and olive oil to a blender. Blend until smooth and creamy. Pour the sauce back into a pot, turn the heat to low, then stir in the grated Pecorino Romano until fully melted.

How to Make Garlicky Breadcrumbs

Follow the same process for the oil and garlic as described above. Once the garlic is fragrant, add the breadcrumbs and a pinch of chili flakes. Toast everything together, stirring every minute or two, until the crumbs are golden and crunchy. Watch the heat closely — breadcrumbs can go from perfect to burnt quickly.

Remove and discard the garlic clove before serving. The crumbs keep their crunch best if you add them right before eating.

Assembling

Fresh pasta cooks fast — usually three to five minutes in generously salted boiling water. Pull it slightly before it's fully done, then transfer it directly into the pan with the cauliflower cheese sauce using a slotted spoon. Toss to coat. If the sauce needs more liquid at this stage, add some of the reserved vegetable broth.

Divide into bowls, top with the toasted garlicky breadcrumbs, a drizzle of your favorite extra virgin olive oil, and more grated Pecorino if you'd like. Enjoy!

Ingredients

Fresh Garganelli Pasta

• 350 grams 00 flour
• 50 grams semolina rimacinata flour
• 228 grams eggs, at room temperature

Cauliflower Cheese Sauce

• 4 cups vegetable broth
• 4 cups cauliflower florets (1 large head)
• 4 large cloves garlic, minced
• 3 tablespoons EXAU Lina EVOO, plus more to taste
• 1 teaspoon salt, or more to taste
• ½ teaspoon pepper, or more to taste
• ½ cup grated Pecorino Romano

Garlicky Breadcrumbs

• 1 garlic clove, smashed
• 2 thick slices of bread, best if a few days old
• Chili pepper flakes, to taste
• Salt, to taste
• 2–3 tablespoons EXAU Lina extra virgin olive oil
• Grated Pecorino Romano, for serving

Directions

Fresh Garganelli Pasta

1. Use a kitchen scale to weigh out your ingredients in separate bowls.
2. Mound the flour on a clean wooden board and make a well in the center. Add the eggs. Use a fork or your fingers to gradually mix the flour into the eggs until a custard-like batter forms in the middle.
3. Fold in any remaining flour and begin kneading. Stretch the dough forward with the heel of your hand, fold it in half, and press down. Roll forward and backward a few times, then rotate 90 degrees. Repeat for about 10 minutes until the dough is smooth and even in color.
4. Shape into a ball, cover, and let rest for at least 30 minutes before shaping.
5. Roll a quarter of the dough through the widest setting on your pasta machine, then through the second and third widest. Fold the sheet into thirds like a brochure and roll through the widest setting again, continuing through until you have a 1 mm-thick sheet (setting 6 on a Marcato pasta machine).
6. Using a pasta wheel or sharp knife, cut the sheet into 1½-inch squares. Wrap each square diagonally around a wooden dowel. Place the rod on a pasta comb and roll across to form ridges.
7. Gently slide the formed garganelli off the rod and place on a pasta rack or lined baking sheet.

Cauliflower Cheese Sauce

1. Bring vegetable broth to a boil. Add the cauliflower florets and simmer until completely fork-tender.
2. Meanwhile, sauté the smashed garlic cloves in two tablespoons of olive oil over medium-low heat, just until fragrant and lightly golden. Don't let them burn.
3. Reserve half of the broth. Transfer the cauliflower, remaining broth, sautéed garlic, and olive oil to a blender. Blend until completely smooth and creamy. Season with salt, pepper, and more olive oil to taste.
4. Pour the sauce back into a pot over low heat. Stir in the grated Pecorino Romano until melted and fully incorporated.

Garlicky Breadcrumbs

1. Tear the bread into chunks and pulse in a food processor until coarse crumbs form.
2. Heat olive oil in a large frying pan over medium heat. Add the smashed garlic and sauté for one to two minutes until fragrant. Add the breadcrumbs and chili flakes. Toast, stirring every couple of minutes, until golden and crispy. Season with salt. Remove and discard the garlic clove before serving.

Assembling

1. Cook the garganelli in a large pot of salted boiling water for three to five minutes. Using a slotted spoon, transfer directly into the pan with the cauliflower cheese sauce. Toss gently to coat, adding reserved broth if you need to loosen the sauce.
2. Divide among bowls. Top with toasted breadcrumbs, a drizzle of extra virgin olive oil, and more grated Pecorino if desired.

Recipe Note: This recipe works best with a hand-cranked pasta machine, wooden pasta board, pasta wheel, and a gnocchi or garganelli board. That said, a rolling pin, sharp knife, and bench scraper can get you there too.

Frequently Asked Questions

Do I have to use fresh pasta?

No. Dried pasta works well with this cauliflower cheese sauce. Penne rigate or rigatoni are good choices since their ridges hold the sauce. Fresh pasta gives a better result overall, but dried pasta is a perfectly delicious option.

Can I make this recipe ahead of time?

Yes. The cauliflower cheese sauce keeps well in the fridge for up to three days. Store it in an airtight container and reheat gently on the stovetop with a splash of broth or water to loosen it back up. Make the breadcrumbs fresh just before serving so they stay crispy.

What cheese works best?

We use Pecorino Romano for a sharp, salty flavor. Parmesan (Parmigiano Reggiano) is a milder alternative that also melts smoothly. You can use either or combine both. Avoid pre-shredded cheeses — they often contain anti-caking agents that prevent them from melting properly.

My sauce is too thin. How do I fix it?

First, try simmering it uncovered on low heat for a few minutes to let some liquid evaporate. If it's still too thin, stir in a tablespoon or two of extra grated cheese. The sauce should thicken as it warms with the pasta, too.

Can I make this recipe vegan?

Yes, with a couple of swaps. Replace the Pecorino Romano with a vegan hard cheese or nutritional yeast. Use a generous hand with the olive oil to add richness. The base cauliflower sauce is naturally dairy-free, so the substitution is simple.
