Why You’ll Love This

  • Authentic:  You’re going to love the flavours in this perfectly roasted garlic cauliflower recipe. It’s based on the classic carbonara sauce made with eggs, bacon and parmesan cheese rather than the Americanized version with heavy cream.
  • Simple:  Although there are different steps in this recipe, you can roast the cauliflower, make the sauce and cook the pasta all at the same time, making this a straightforward recipe.
  • Delicious:  I love pretty much all Italian dishes and this pasta carbonara with cauliflower sauce is really good. It’s such a simple dish with not many ingredients but it’s beautifully balanced.

Roasted Cauliflower Carbonara Ingredients

The cauliflower and pasta are the main ingredients here, and you can choose from regular or gluten free pasta. Garlic, bacon, egg yolks, parmesan cheese, and red pepper flakes also go into the dish. And then you will need chopped fresh parsley and some extra grated parmesan cheese for the garnish.

Substitutions and Variations

You can substitute pancetta for the bacon if you like, or add some green onions as well as the garlic. You could also add peas if you want a pop of green in there, or use another kind of cheese (maybe pecorino) with the parmesan or instead of it.

Freshly ground black pepper or even smoked paprika might be a nice addition. Lemon zest or a squeeze of fresh lemon juice will add some zing to the dish.

What to Serve with Cauliflower Carbonara

If you prefer not to serve the carbonara over hot pasta, you could have it over rice instead or just as it is for a lighter meal. If you do want pasta, then it’s up to you which pasta shape to use. I like to have rigatoni pasta with this.

Cauliflower Carbonara FAQs

Doesn’t carbonara have heavy cream in it?

You can find cream-based carbonara sauce recipes or at the grocery store but the authentic Italian way of making carbonara relies on egg yolks and cheese for creaminess. Add a splash of cream if you want but this is a rich, creamy dish without it.

How do you stop the eggs from scrambling?

Take the pot off the heat before mixing in the eggs. There will be enough residual heat to cook the eggs sufficiently but too much heat will scramble them which might be good for egg fried rice but isn’t what you want from carbonara.

    The biggest mistake I made with this carbonara was underestimating how much people would want to eat. It was gone before I could even get a look at seconds!
