1-First Step: Cook the Pasta Bring a large pot of salted water to a boil. Add 12 oz rotini pasta and cook according to package, usually 7-9 minutes for al dente. Drain well, but save 1/4 cup pasta water if sauce needs loosening later. This base ensures your pasta with bell peppers soaks up flavors without sogginess.

2-Second Step: Sauté Sausage and Bell Peppers While pasta boils, heat a medium skillet over medium heat, no oil needed as sausage releases fat. Add 14 oz sliced smoked sausage and 2 sliced bell peppers. Sauté 5-8 minutes, stirring occasionally, until sausage turns golden and peppers soften with crisp edges. This builds fond for richer sauce in your spicy creamy sausage pasta with bell peppers. Tip: Medium heat prevents burning; if crowded, use a larger pan.

3-Third Step: Build the Creamy Sauce Pour in 2 cups heavy cream and 1 tablespoon Cajun seasoning. Stir to combine, scraping any bits from the pan. Reduce heat to low and simmer 4 minutes. Sauce will thicken slightly as it reduces. Taste and adjust spice; less for kids. For low-fat, use half-and-half but simmer longer. This creates the heart of your quick creamy sausage pasta skillet.

4-Fourth Step: Add Parmesan and Combine Remove skillet from heat. Stir in 1/2 cup grated Parmesan until melted and smooth. Add drained pasta directly to the skillet. Toss gently to coat every noodle in creamy goodness. If too thick, splash in reserved pasta water. Let sit 1 minute for flavors to meld. Dairy-free? Use nutritional yeast here.
