Step 1

Bring a large pot of salted water to a boil over medium-high heat. Add the linguine noodles and cook until al dente according to package directions, 8 to 9 minutes. Drain well and set aside.

Step 2

While the pasta boils, heat the butter and olive oil in a large skillet over medium heat, stirring occasionally until the butter melts. Add the shrimp and garlic. Cook, stirring occasionally and turning the shrimp, until the shrimp are pink, opaque, and cooked through, 2 to 3 minutes.

Step 3

Stir in the lemon juice, parsley, lemon zest, lemon slices, salt, pepper, and red pepper flakes until well combined. Reduce to medium-low heat.

Step 4

Add the cooked pasta and toss to combine. Serve immediately topped with Parmesan cheese.
