Bring a large pot of salted water to a boil. Add the fettuccine and cook according to the package instructions until al dente. Drain the pasta, reserving a little pasta water for later, and set aside.
Preheat your oven to 400°F (200°C). Slice the French bread in half lengthwise. In a small bowl, mix olive oil, garlic powder, and Italian seasoning. Brush this mixture generously over the cut sides of the bread. Place the bread on a baking sheet, cut side up, and bake for 8-10 minutes or until golden and crisp on the edges. For extra crispiness, you can broil for an additional 1-2 minutes—just watch closely to avoid burning. Once done, slice the garlic bread into bite-sized pieces perfect for mixing into the pasta.
In a large skillet, melt the butter over medium heat. Add the minced garlic and sauté until fragrant, about 1-2 minutes—be careful not to let it brown. Pour in the heavy cream and bring to a gentle simmer. Stir in the grated Parmesan cheese and whisk continuously until the cheese melts and the sauce thickens slightly. Season with salt and black pepper to taste.
Add the cooked fettuccine to the skillet with your Alfredo sauce. Toss gently to coat the pasta evenly. If the sauce feels too thick, add a splash of reserved pasta water until you reach your desired consistency.
Fold in the chopped turkey bacon and the toasted garlic bread pieces. The bread will soak up some of the sauce while retaining a satisfying crunch—this is the magic of Garlic Bread Alfredo Pasta!
Transfer the pasta to serving plates or a large bowl. Sprinkle with freshly chopped parsley for a burst of color and freshness. Serve immediately with extra garlic bread on the side.
