Step 1

In a large pot, bring 4 quarts water and 1 tablespoon salt to boil. Add fettuccine and cook until al dente, about 9 to 11 minutes. Reserve 1 cup of pasta water and then drain well.

Step 2

Meanwhile, in a large skillet over medium heat, heat butter and oil until melted and combined. Add onion, lemon zest, red pepper flakes, 1 teaspoon salt, and a pinch of black pepper. Cook until softened, about 8 minutes.

Step 3

Stir in artichokes and sauté until heated through, about 3 minutes. Stir in lemon juice and remove from heat.

Step 4

To a large serving bowl, add drained pasta, artichoke mixture, 1/2 cup reserved cooking liquid, and cheese. Toss until combined, adding more liquid if needed to bring the sauce together. Season to taste with salt and pepper.
