In a skillet over medium heat, toast the pine nuts, stirring constantly until slightly golden in color. Set aside.
Cook the pasta in a pot of salted water until 1-2 minutes shy of the package instructions.
Reserve some cooking liquid and drain the pasta. Pour the pasta into the skillet. Drizzle with olive oil and stir.
In a food processor, add garlic, parsley, oregano and thyme. Blend until mostly smooth.
Add 1 cup of the peas, ricotta, lemon juice and zest, 2 tablespoons olive oil, salt , and black pepper. Pulse until blended, but not smooth.
Add the ricotta mixture to the pasta along with 1/4 cup of the pasta water and stir it up. If it’s too thick, add a bit more water to smooth it out. Add the remaining peas, Parmesan, and red pepper flakes.
Top with toasted pine nuts and drizzle on remaining olive oil.
