Looking for a quick weeknight dinner that feels like a little luxury? This Avocado Pesto Pasta with Crispy Prosciutto combines a velvety, creamy sauce with a salty, crunchy topping.

This Avocado Pesto Pasta with Crispy Prosciutto is a creamy, fun alternative to traditional pesto. In this version, the classic recipe gets a rich upgrade from ripe avocados, creating a velvety sauce texture without any dairy. Best of all, it takes minimal effort: add the ingredients to a blender, blend until smooth, toss with the pasta, and dinner is served.

The prosciutto adds a layer of umami to the dish with its crispy texture and saltiness, while the avocado provides healthy fats. The cashews lend protein and fiber, but most of all, they make the sauce impossibly creamy and rich. And yet, somehow, this pasta manages to remain bright and fresh.

One detail that adds another layer of depth is the roasted garlic. While it does require extra time in the oven, that time is completely passive. Although this step might sound unnecessary, it is entirely worth it: as the garlic roasts, it loses its pungent bite and turns sweet and caramelized, adding a deep flavor to your sauce.

You can use up to a whole head of garlic, depending on your taste. I advise roasting a full head and storing any leftovers in the fridge for other recipes – it works beautifully in salad dressings, dips, and sauces. Of course, you can also skip the roasting altogether and use raw garlic cloves for a punchier, sharper flavor.

Ingredients

Roasted Garlic: Roasting breaks down the garlic’s harsh, pungent sulfur compounds into sweet, complex sugars through caramelization. This provides a deep and slightly sweet backdrop that mellows out the bright basil without overpowering the dish.

Avocado: the star of the show, the natural emulsion base for the sauce. Its dense, healthy monounsaturated fats create a velvety, thick coat over the pasta strands, entirely eliminating the need for heavy dairy cream.

Cashews: they contain a high starch content that when blended, absorb liquid and act as a structural binder, preventing the avocado from separating or becoming watery.

Olive Oil: a little bit is enough to emulsify the sauce.

Prosciutto: Thinly cured Italian ham that crisps rapidly in this pan, it’s here purely for texture and flavor contrast, adding a nice crunch and intense saltiness to cut through the buttery fat of the avocado and nuts.

Lemon: The citric acid acts as a natural antioxidant that lowers the pH level of the sauce, deactivating the polyphenol oxidase (the enzyme causing oxidation), keeping your green sauce from turning brown. And it adds a bright, zesty note to balance out the richness of the sauce.

Tips and Variations

Save the pasta water: Keep a half-cup of the boiling pasta water before draining. Splash the starchy water in during the final toss to make the sauce glossy.
Prevent browning: The lemon juice prevents the avocado from turning brown immediately. However, because this sauce oxidizes quickly when exposed to air, it is best served and eaten immediately after mixing.
Nut-free substitution: Try swapping the cashews for toasted pepitas (pumpkin seeds). I’ve never tried it myself, but apparently they provide the exact same structural thickness!
Vegan alternative: Skip the prosciutto and parmesan or replace with thinly sliced shiitake mushroom caps or cubed tempeh. Sauté them in olive oil with a pinch of smoked paprika and sea salt until completely crisp to mimic the salty crunch of the pork.
Gluten-free option: Swap the standard wheat pasta for a sturdy gluten-free alternative like brown rice or chickpea-based fusilli or spaghetti.

FAQ

Can I make this recipe completely raw? Yes. If you are short on time, you can skip the oven roasting entirely. However, because raw garlic is intensely sharp and pungent, you must scale the amount back. Swap the half-head of roasted garlic for 1 small raw garlic clove to keep the flavor balanced.

Why did my avocado pesto turn brown, and can I fix it? While the lemon juice in this recipe slows the oxidation process down, the sauce will eventually dull if left out, so it is highly recommended to serve and eat this dish immediately after tossing.

How do I store and reheat leftovers? Avocado sauces do not reheat well in microwaves because intense direct heat splits the oils and degrades the flavor. If you have leftovers, pack the pasta into an airtight container and refrigerate. Eat it cold the next day as a chilled pasta salad, or gently bring it to room temperature before serving.
