Gather all your ingredients for the High Protein Creamy Beef Pasta. If using fresh tomatoes, chop them into small pieces.

Fill a large pot with water and bring it to a boil. Add a pinch of salt and stir in the pasta, cooking it according to the package instructions until al dente, usually around 8-10 minutes. Drain the pasta in a colander and keep it warm.

In a large skillet, heat a drizzle of olive oil over medium-high heat. Add the lean ground beef and cook for 5-7 minutes, breaking it apart until browned.

Stir in the diced tomatoes, cooking for an additional 3-4 minutes until heated through and juices are released.

Reduce heat to low and add Greek yogurt and Parmesan cheese, stirring until combined and creamy, about 2-3 minutes.

Add the drained pasta into the skillet and mix well, ensuring each strand is coated with the creamy beef mixture. Toss gently for about 1-2 minutes, adding pasta water if needed.
