This creamy avocado pesto pasta is a quick, plant-based dinner made with ripe avocado, fresh basil, lemon, garlic, and nutritional yeast. The avocado creates a naturally smooth sauce without cream, while reserved pasta water helps it cling to every strand. Cherry tomatoes add fresh color and a lightly sweet contrast. Because the sauce requires no cooking, the entire meal can be ready in about 20 minutes.

Recipe at a Glance
Prep Time: 10 minutes | Cook Time: 10 minutes | Total Time: 20 minutes
Servings: 4
Ingredients
- 12 ounces spaghetti, linguine, or another favorite pasta
- 1 large ripe avocado, peeled and pitted
- 1 packed cup fresh basil leaves
- 2 tablespoons fresh lemon juice, plus more to taste
- 1 small garlic clove, peeled
- ¼ cup extra-virgin olive oil
- 2 tablespoons nutritional yeast
- ½ teaspoon salt, plus additional salt for the pasta water
- ¼ teaspoon freshly ground black pepper, plus more for serving
- ¼ to ½ cup reserved pasta water, as needed
- 1 cup halved cherry tomatoes, optional
Directions
- Bring a large pot of generously salted water to a boil. Add the pasta and cook according to the package directions until al dente.
- Before draining the pasta, carefully reserve at least ½ cup of the starchy cooking water. Drain the pasta, but do not rinse it.
- While the pasta cooks, place the avocado, basil, lemon juice, garlic, olive oil, nutritional yeast, salt, and black pepper in a food processor or blender.
- Blend until mostly smooth. Add ¼ cup of the reserved pasta water and blend again. If the sauce is too thick, add more pasta water 1 tablespoon at a time until it becomes creamy and pourable.
- Return the drained pasta to the warm pot with the heat turned off. Add the avocado pesto and toss until every strand is evenly coated. Keeping the sauce away from direct heat helps preserve its fresh flavor and green color.
- Gently fold in the cherry tomatoes, if using. Taste and adjust with additional lemon juice, salt, or black pepper. Serve immediately while the pasta is warm and creamy.
Helpful Recipe Tips
- Choose a ripe avocado: It should yield slightly when gently pressed but should not feel mushy or have deeply sunken areas.
- Reserve the pasta water: Its starch helps loosen the sauce while allowing it to stay attached to the pasta.
- Use fresh lemon juice: Lemon balances the richness of the avocado and helps slow discoloration.
- Toss the sauce off the heat: Direct heat can make avocado sauce darker and may change its fresh flavor.
- Serve promptly: The sauce has its best color and creamiest consistency shortly after it is blended.
Variations and Substitutions
- Use penne, rotini, bow-tie pasta, or another shape that holds creamy sauce well.
- Choose a certified gluten-free pasta when preparing the recipe for someone avoiding gluten.
- Replace some of the basil with baby spinach, arugula, or fresh parsley.
- Add steamed broccoli, green peas, roasted asparagus, or sautéed mushrooms for more vegetables.
- For texture, finish each serving with toasted pine nuts, walnuts, pumpkin seeds, or hemp hearts.
- If nutritional yeast is unavailable, simply omit it and adjust the salt and lemon juice to taste.
Serving Suggestions
Serve creamy avocado pesto pasta as a quick lunch or light dinner. It pairs well with a simple green salad, roasted vegetables, garlic bread, or a cup of vegetable soup. The cherry tomatoes shown in the photograph provide color and acidity, but sliced roasted red peppers or fresh diced tomatoes also work well. A final sprinkle of black pepper, fresh basil, or nutritional yeast gives each bowl a finished appearance.
Make-Ahead Instructions
The ingredients may be measured in advance, but wait to cut the avocado and blend the pesto until close to serving time. The pasta may be cooked slightly ahead and tossed with a small amount of olive oil to reduce sticking. For the freshest flavor and color, combine the warm pasta and avocado sauce immediately before serving.
Storage and Reheating
Transfer leftovers to a covered container and refrigerate promptly. For the best color and texture, enjoy them within 1 to 2 days. The avocado sauce may darken during storage even when it remains usable. Stir in a small amount of lemon juice or water before serving. Gentle reheating is best: warm the pasta briefly over low heat or in short microwave intervals, stirring between intervals. The pasta may also be enjoyed chilled as a pasta salad.
Frequently Asked Questions
How do I keep avocado pesto from turning brown?
Use fresh lemon juice, prepare the sauce shortly before serving, and limit its exposure to air. When storing leftovers, press food-safe wrap against the surface before closing the container.
Can I make this pasta without a blender?
Yes. Finely chop the basil and garlic, then mash them thoroughly with the avocado, lemon juice, nutritional yeast, salt, and pepper. Whisk in the olive oil and pasta water until the mixture becomes as smooth as possible.
Why is my avocado sauce too thick?
The size and ripeness of avocados vary. Add reserved pasta water 1 tablespoon at a time and toss again until the sauce coats the pasta without becoming watery.
Can frozen avocado be used?
Thawed frozen avocado can work, although its flavor and texture may be slightly different from fresh avocado. Drain away excess liquid before blending and adjust the lemon juice and seasonings after tasting.
Is this recipe vegan?
Yes. The recipe uses nutritional yeast instead of dairy cheese. Check the pasta package if you need to confirm that the chosen pasta contains no egg or other animal-derived ingredients.
