Cajun Shrimp Fettuccine Alfredo

Bring a large pot of lightly salted water to a boil. Cook fettuccine according to package directions until tender yet slightly firm to the bite, 7 to 8 minutes. Drain, reserving 1/4 cup of pasta water.

Combine flour and Cajun seasoning in a small bowl. Pat shrimp dry, add to the bowl, and toss to coat.

Heat butter and olive oil in a skillet over medium-high heat. When butter bubbles, add shrimp and cook until opaque and pink, about 2 minutes per side. Transfer shrimp to a clean bowl. Add garlic to the skillet and cook until fragrant, about 30 seconds. Add broth to the skillet and scrape up any brown bits.
