Bottom Line Up Front (Quick Answer):
To make 15-minute creamy avocado lime pasta, boil 10 oz fettuccine or linguine in salted water until al dente (reserve 1/2 cup pasta water). While pasta cooks, blend 2 ripe Haas avocados, 1 packed cup fresh cilantro leaves, 3 garlic cloves, 3 tbsp lime juice, 3 tbsp extra virgin olive oil, 1/2 tsp salt, and 1/3 cup warm pasta water in a blender until silky smooth. Drain hot pasta and immediately pour the raw avocado crema over the warm noodles, tossing until evenly coated. Fold in 1 cup halved cherry tomatoes and 2 tbsp toasted pine nuts.
Why This Recipe Conquers Weeknights
- Raw Blended Silkiness: Blending ripe avocados with warm starchy pasta water creates an ultra-velvety cream sauce without a single drop of heavy cream or dairy.
- Lime Juice Oxidation Barrier: Fresh lime juice not only provides bright zesty flavor but prevents the avocados from browning, keeping the sauce vibrant spring green.
- Residual Heat Coating: Tossing raw sauce with hot drained pasta off the stove gently warms the sauce without scorching delicate avocado fats.

Ingredients
Step-by-Step Instructions
- Boil Pasta & Reserve Water: Bring a large pot of salted water to a rapid rolling boil. Add fettuccine and cook until al dente according to package instructions (about 9–10 minutes). Before draining, carefully ladle out 1/2 cup of starchy pasta water. Drain pasta and place in a large serving bowl.
- Blend Velvet Avocado Crema: While pasta boils, place the scooped avocado flesh, cilantro, garlic cloves, fresh lime juice, olive oil, salt, black pepper, and 1/3 cup of warm reserved pasta water into a high-speed blender or food processor. Blend on high for 60 seconds until completely silky, glossy, and vibrant green.
- Toss with Warm Pasta Off Heat: Immediately pour the smooth avocado sauce over the steaming drained fettuccine. Toss gently with tongs for 60 seconds until every ribbon of pasta is generously coated in velvety green sauce. (Add an extra splash of reserved pasta water if needed to loosen).
- Fold in Fresh Toppings: Toss in halved cherry tomatoes and half of the toasted pine nuts, distributing evenly.
- Garnish & Serve Immediately: Divide into pasta bowls. Top with remaining toasted pine nuts, fresh cilantro leaves, cracked black pepper, and a sprinkle of crumbled cotija or parmesan. Serve right away with lime wedges!

Elena’s Chef Pro-Tip
Chef Secret:
Never heat avocado sauce in a pan on the stove! Cooking avocado over direct heat breaks down its delicate monounsaturated fats and creates an unpleasant bitter aftertaste. The steaming heat of freshly drained hot pasta is all that's required to warm the sauce to perfect eating temperature.
