Cook pasta in large pot of boiling salted water until tender but still firm to bite, stirring occasionally.
Meanwhile, heat the olive oil in heavy large skillet over medium heat. Add the shallot and garlic; sauté until soft, about 2 minutes. Add the lemon zest.
Drain the pasta, reserving about 3/4 cup of the pasta water. Pour pasta into the skillet. Add the lemon juice and arugula. Add the reserved pasta water and gently toss until arugula is wilted, about 1 minute. Top with burrata cheese and gently stir until cheese is melted. Season with salt and black pepper, to taste.
Place pasta into serving bowls or plates and top with crushed red pepper, if desired. Serve warm.
