Bring 4 quarts salted water to boil in large pot.
Squeeze thawed artichokes dry between paper towels. Add olive oil to
skillet and heat over medium. Add artichokes, sliced garlic and kosher
salt to taste. Saute until artichokes and garlic are golden brown.
Add spaghetti to salted boiling water with a few drops of olive oil and
cook until al dente. Remove with tongs to skillet with artichokes &
garlic. Stir in parsley, lemon juice & zest, red pepper flakes, and
several ladles of pasta cooking water and toss. Pasta will soak up the
liquid. Season with salt and pepper to taste. Serve with grated Parmesan
cheese.
