How to make asparagus pesto sauce
Prepare the ingredients: Rinse the asparagus and snap off the rough ends. Rough chop the garlic clove, measure the seeds and olive oil.
STEP 1: Arrange the asparagus spears in a single layer on a parchment-lined baking sheet and brush them with a thin layer of olive oil.
(Skip step 1 and 2 if you are using leftover asparagus.)
STEP 2: Roast the asparagus in the oven until it’s fork-tender, about 15 to 20 minutes. Remove the asparagus and let it cool off.
STEP 3: Once the asparagus is cool enough to handle, chop it into chunks about 1 inch in size and place it in the food processor with the sunflower seeds and garlic.
STEP 4: Process the mixture into small pieces.
STEP 5: Add the basil, and process once again while adding the oil through the feeding tube.
STEP 6: The pesto will be slightly thick, if you prefer thin pesto adjust the sauce to your preference by adding more oil or water.

Pesto ingredient notes and substitutions
The full list of ingredients to make this homemade pesto sauce recipe is above. Below are notes about some of the ingredients along with ideas for substitutes.
Asparagus. I like to use roasted asparagus in this recipe, but you can use asparagus that is cooked any way that you like; steamed, blanched, or grilled. It’s also a great way to use up leftover asparagus.
Basil. Fresh basil leaves add a ton of flavor to pesto sauce and it doesn’t take over the earthy flavors of the asparagus. If you don’t like to use basil, it can be left out.
Sunflower Seeds. Pesto is usually made with pine nuts which have become very expensive. You can use them in this recipe in place of sunflower seeds and you can also use walnuts or pistachio nuts
What to serve with asparagus pesto sauce
There are so many ways to enjoy asparagus pesto. Serve it garnished with lemon zest and a pinch of salt over al dente pasta, rice, or zucchini noodles or add it to your favorite pasta salad.
Asparagus pesto also tastes great drizzled over freshly sliced tomatoes, or brushed on grilled meat, spread on a sandwich, on a pizza crust or flatbread with sliced tomatoes, basil, and mozzarella cheese.
How to store leftovers
Leftover asparagus pesto will last in the refrigerator for three to four days in an airtight container. Use the leftover sauce as a spread on sandwiches or drizzle it over cooked vegetables.
You can also freeze this delicious sauce, which will extend the asparagus season too. Asparagus pesto can be frozen for up to six months in a freezer container or placed into an ice cube tray for individual-sized portions.
Once the pesto is frozen solid in individual portions, remove it from the ice cube tray and store it in a bag. Individual portions are great for adding to homemade marinara sauce and even to homemade salad dressing!
Recipe variations
Change up the seeds and use an equal amount of chopped walnuts, almonds, or cashews.
Spinach and asparagus pesto – Add a handful of baby spinach leaves to the food processor with the asparagus.
Sun-dried tomato and asparagus pesto – Add a 1/4 cup of sun-dried tomatoes to the food processor with the asparagus.
Recipe FAQs
Pesto sauce can become thick when it is stored in the refrigerator, just before serving gradually stir in a little bit of olive oil or water until the sauce reaches a consistency that you like. If you are making pasta with your pesto, the pasta water works well for this.
Place a steamer basket filled with trimmed asparagus into a pan with a little bit of water. Cover the pan and steam the asparagus for about 8 minutes.
Or add one to two inches of water to a large skillet and place the asparagus in the skillet. Cover and steam for 6 to 8 minutes.
