Step 1: Cook the Pasta

1. Bring a large pot of salted water to a boil. Add the pasta and cook according to the package instructions until al dente. Reserve 1 cup of pasta water, then drain and set the pasta aside.

Step 2: Brown the Sausage

1. Heat the olive oil in a large skillet over medium-high heat.
2. Add the sausage, breaking it into small pieces with a wooden spoon. Cook for 5-7 minutes, or until the sausage is browned and cooked through.
3. Use a slotted spoon to remove the sausage from the skillet and set it aside, leaving the rendered fat in the pan.

Step 3: Sauté the Vegetables

1. In the same skillet, add the sliced onions and bell peppers. Cook over medium heat for 5-7 minutes, stirring occasionally, until the vegetables are softened and slightly caramelized.
2. Add the minced garlic, smoked paprika, red pepper flakes (if using), salt, and black pepper. Stir and cook for 1-2 minutes, until fragrant.

Step 4: Make the Creamy Sauce

1. Reduce the heat to medium-low. Add the tomato paste to the skillet and stir to combine with the vegetables. Cook for 1 minute to enhance its flavor.
2. Pour in the chicken broth, scraping the bottom of the skillet to deglaze and release any flavorful bits.
3. Stir in the heavy cream and Italian seasoning. Let the sauce simmer for 2-3 minutes, allowing it to thicken slightly.

Step 5: Combine Everything

1. Return the cooked sausage to the skillet and stir to combine with the sauce and vegetables.
2. Add the cooked pasta to the skillet, tossing to coat it evenly in the sauce. If the sauce is too thick, add a splash of reserved pasta water to loosen it.
3. Stir in the grated Parmesan cheese, letting it melt into the sauce for added creaminess.

Step 6: Serve and Garnish

1. Divide the Creamy Sausage and Peppers Pasta among bowls.
2. Garnish with fresh parsley, extra Parmesan cheese, or a sprinkle of crushed red pepper flakes for added flavor and presentation.
3. Serve immediately and enjoy!
