Cook the Pasta: Begin by boiling a large pot of salted water. Add 8 oz of fettuccine pasta and cook according to package instructions, until al dente. Once cooked, drain the pasta and reserve 1/2 cup of the pasta water for later use.
Prepare the Chicken: While the pasta cooks, take 1 lb of bite-sized chicken breast and season it with 1/2 tsp paprika, salt, and pepper. In a large skillet, heat 2 tbsp of olive oil over medium heat. Add the seasoned chicken to the skillet and cook for about 4-5 minutes, or until the chicken is golden brown and cooked through. Remove the chicken from the skillet and set it aside.
Make the Garlic Butter Sauce: In the same skillet, reduce the heat to low and add 2 tbsp of unsalted butter. Once melted, add 3 minced garlic cloves and sauté until fragrant, about 1 minute. Return the chicken to the skillet and toss everything to coat in the garlic butter, cooking for an additional 2 minutes.
Prepare the Creamy Parmesan Sauce: In a separate saucepan, melt another 2 tbsp of butter over medium heat. Add 2 minced garlic cloves and sauté until fragrant, about 1 minute. Pour in 1 cup of heavy cream and bring it to a gentle simmer. Gradually whisk in 1 cup of grated Parmesan cheese until it’s completely melted and smooth. Season the sauce with salt and pepper to taste.
Combine Pasta, Sauce, and Spinach: Once the creamy Parmesan sauce is ready, add the drained pasta and 2 cups of fresh spinach to the pan. Toss everything together until the spinach wilts and the pasta is evenly coated. If the sauce is too thick, adjust the consistency using the reserved pasta water.
Serve: Once everything is well mixed, plate the creamy pasta, and top it with the buttery chicken bites. You can garnish with extra Parmesan cheese or freshly chopped parsley for added flavor and presentation. Enjoy your delicious meal!
