I got this recipe from Betty Crocker's website, and it's a good one!

I made it without the pine nuts though, and instead of the 1 cup fresh basil, I used  3/4 cup spinach and 1/4 cup cilantro.

I also made an entire bag of pasta (I think it was a1 lb bag) and the pesto recipe was plenty for all that pasta.When it was made, I filled my bowl, mixed in a little alfredo and then topped with parmesan and a bit of dried basil.

Here's what it looked like, don't be disenchanted by it's color!

Rigatoni with Basil Pesto

Rigatoni

1/2	teaspoon salt (for cooking pasta), if desired
3	cups uncooked rigatoni pasta (8 oz)

Basil Pesto

1	cup fresh basil leaves
2	cloves garlic
1/3	cup grated Parmesan cheese
1/3	cup olive or vegetable oil
2	tablespoons pine nuts or walnut pieces

1. 1Fill a 4-quart pan half full of water. Add 1/2 teaspoon salt if desired. Cover with lid; heat over high heat until the water is boiling rapidly. Add the pasta. Heat to boiling again. Boil uncovered 14 to 16 minutes, stirring frequently, until tender but not mushy. While the water is heating and the pasta is cooking, continue with the recipe to make the pesto.
2. 2To measure basil, firmly pack basil leaves into a measuring cup. Use a measuring cup for measuring dry ingredients. Rinse the basil leaves with cool water, and pat dry thoroughly with a paper towel or clean, dry kitchen towel. Peel the garlic cloves.
3. 3In a food processor or blender, place the basil leaves, garlic, cheese, oil and pine nuts. Cover and process, stopping occasionally to scrape sides with rubber spatula, until smooth.
4. 4Place a strainer or colander in the sink. Pour the pasta in the strainer to drain, and place in a large serving bowl or back in the Dutch oven. Immediately pour the pesto over the hot pasta, and toss until pasta is well coated. Serve with additional grated Parmesan cheese if desired.

Expert Tips

EXPERT TIPS:
Substitute 3/4 cup firmly packed fresh cilantro leaves and 1/4 cup firmly packed fresh parsley leaves for the fresh basil.
Substitute 1 cup firmly packed fresh spinach leaves and 1/4 cup firmly packed fresh basil leaves (or 2 tablespoons dried basil leaves) for the 1 cup fresh basil.
Use pesto immediately because it will darken as it is exposed to the air. Or store the pesto immediately by placing in an airtight container and refrigerate up to 5 days or freeze up to 1 month.
