This is a tasty yet simple prep for pasta, perfect for a weeknight meal. Roasted garlic adds great depth of flavor—spread any leftover cloves on slices of toasted crusty bread. The garlic can be made in advance and kept in the fridge for about a week (after cooling, squeeze out the softened garlic from each clove and store in a sealed jar). I’ve suggested thin spaghetti for this dish, but choose any shape you like, cooked according to package directions.
Ingredients
- 1 head garlic
- 5 tablespoons extra virgin olive oil, divided, plus more for drizzling
- 3 teaspoons coarse sea salt, divided use, plus more to taste
- 8 ounces spinach, trimmed as needed (see Healthy Ingredient Spotlight in our weekly newsletter)
- 1 pound thin spaghetti or other pasta
- 2-ounce chunk Parmigiano-Reggiano, plus more for serving
- 1/2 teaspoon pepperoncini or red pepper flakes
- 1/2 teaspoon freshly ground black pepper, plus more to taste
Directions
Step 1
Peel off the papery outer layers from the garlic while keeping the bulb intact. Slice about a 1/2 inch off the top; you can trim the roots but don’t cut them off or the cloves won’t hold together. Place the garlic cut side up on a piece of parchment paper, then drizzle 1/2 tablespoon of olive oil on the exposed cloves. Fold the long sides of the parchment paper over the garlic, then fold the ends underneath to make a packet. Place on a rimmed sheet pan and roast for 45 to 60 minutes, until the cloves are golden and soft and start to shrink away from the peel.
Step 2
Prepare an ice bath by filling a large bowl with ice and cold water; set aside. Fill a stockpot with 4 quarts of water and bring to a boil. Add 2 teaspoons of salt and the spinach. Cook for 2 minutes, then use a spider skimmer or slotted spoon to move the spinach to the ice bath (this chill-down helps retain its color), leaving the pot of boiling water on the stove.
Step 3
Add the pasta to the pot of boiling water and cook until tender, about 10 minutes. When the pasta is half cooked, prepare the sauce. Pare any rind off the cheese, cut it into cubes, place in your food processor, and pulse until the cheese is nearly a powder. Remove 1/4 cup of cheese from the work bowl and set aside. Add in the spinach, 6 cloves roasted garlic, the pepperoncini or red pepper flakes, the remaining salt, and the black pepper. Process until smooth, adding 1/4 to 1/2 cup of liquid from the pasta pot if needed.
Step 4
Drain the pasta, transfer it to a large bowl, and toss with the sauce, thoroughly coating it. Serve each portion with a drizzle of olive oil and a sprinkle of the reserved cheese.
