- Kosher salt
- 1/4 cup olive oil, plus more for serving
- 3 large shallots, chopped
- 5 garlic cloves, finely chopped
- 1/2 teaspoon crushed red pepper flakes, plus more for serving
- 2 small bunches of broccolini
- 12 ounces tubetti or other short tube pasta
- 1 1/2 ounces Parmesan, finely grated, plus more for serving
- Lemon wedges (for serving)
- Bring 6 quarts water to a boil in a large pot; season with salt. The water should taste like ocean water, so keep adding salt until it tastes very, very saline (you should use around 1/4 cup).
- Meanwhile, heat 1/4 cup oil in a large skillet over medium. Add shallots, garlic, and 1/2 tsp. red pepper flakes; season lightly with salt. Cook, stirring occasionally, until shallots are translucent, about 4 minutes. Remove from heat and set aside.
- Remove florets from broccolini and cut into bite-size pieces. Slice stems into 1/2″ pieces. Add to boiling water. Cook 1 minute, then, using a spider or slotted spoon, transfer to reserved skillet.
- Return water in pot to a boil and cook tubetti, stirring occasionally, until very al dente, 7–9 minutes. Drain, reserving 3/4 cup pasta cooking liquid. Add pasta and pasta cooking liquid to skillet, tossing to combine. Cook over medium-high heat, gradually adding 1 1/2 oz. Parmesan and tossing often, until pasta is al dente and liquid has reduced to form a thick, glossy sauce, about 4 minutes. Taste and season with more salt if needed.
- To serve, squeeze lemon wedges over pasta, drizzle with oil, and top with more grated Parmesan and red pepper flakes.
