Heat your oven to 425˚F. Give the sweet potatoes a good scrub and cut into ¼” cubes. Place on a sheet tray and toss with the minced garlic, olive oil, and salt. Roast until the sweet potatoes are tender and starting to brown, 25 to 30 minutes.
While the sweet potatoes are roasting, prepare the chimichurri.
Finally, cook the pasta. Bring a pot of salted water to a boil. Add the Chickpea Casarecce and cook until al dente, 7 to 8 minutes. Drain, reserving 1 cup of the pasta water, and return the pasta back to the pot.
When the sweet potatoes are done, add them to the pasta along with ⅓ to 1/2 cup of the chimichurri. Stir to combine and serve hot. This pasta can also be served chilled. Whichever way you go, keep extra chimichurri on hand- the pasta likes to soak up the sauce and you might need a bit more!
