Step 1: Cook the Pasta
Boil the Fettuccine: In a large pot of salted boiling water, cook the 12 oz of fettuccine pasta according to package instructions until al dente. Drain and set aside, reserving about 1 cup of pasta water for later.
Step 2: Prepare the Beef

Sear the Beef: In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Add the seasoned beef strips and sear for about 3-5 minutes, or until they are browned and cooked to your desired level of doneness. Remove the beef from the skillet and set it aside.
Step 3: Sauté the Aromatics
Cook Onions and Garlic: In the same skillet, add 2 tablespoons of butter, followed by the diced onion. Sauté for about 2-3 minutes until the onion is soft and translucent. Add the minced garlic and cook for an additional 30 seconds until fragrant.
