Boil a large pot of salted water and cook the pasta according to package instructions until al dente. Drain and set aside.
In a large skillet over medium heat, melt the butter. Once melted, add the minced garlic and sauté for about 1 minute, or until fragrant.
Stir in the smoked paprika, chili powder, dried oregano, and cayenne pepper. Cook for another minute, allowing the spices to bloom in the butter.
Add the diced chicken to the skillet and season with salt and pepper. Cook until the chicken is golden brown and cooked through, about 5-7 minutes.
Once the chicken is cooked, add the halved cherry tomatoes and chopped spinach to the skillet. Cook for an additional 2-3 minutes, until the spinach is wilted and the tomatoes are slightly softened.
Pour in the heavy cream and stir to combine, letting it simmer for 2-3 minutes to thicken slightly.
Add the cooked pasta into the skillet, tossing everything together until the pasta is well coated in the buttery sauce. Adjust seasoning if necessary.
Serve immediately, garnished with fresh parsley.
Notes
Serve in a large bowl, sprinkle extra chopped parsley on top, and place a few whole cherry tomatoes for visual appeal.
