Equipment

  • Large deep skillet or sauté pan Use a heavy-bottomed pan to prevent the sauce from scorching
  • Large pot For boiling pasta
  • Wooden spoon or spatula
  • Sharp knife

Ingredients

  • 1 lb penne pasta or bowtie pasta
  • 1 tablespoon olive oil
  • 1 lb smoked andouille sausage sliced into rounds
  • 1 medium onion diced
  • 1 red bell pepper diced
  • 1 green bell pepper diced
  • 3 cloves garlic minced

  • 1 cup chicken broth
  • 1 cup Parmesan cheese freshly grated
  • 0.5 teaspoon smoked paprika
  • 1 cup fresh spinach loosely packed
  • salt and black pepper to taste
  • fresh parsley chopped, for garnish

Instructions

  • Bring a large pot of salted water to a boil and cook the penne pasta until al dente. Drain and set aside, reserving a little pasta water.
  • Heat olive oil in a large skillet over medium heat. Add the sliced andouille sausage and cook until browned and slightly crispy. Remove and set aside.
  • Add the onion, red bell pepper, and green bell pepper to the skillet. Cook until softened, then stir in the garlic.
  • Sprinkle the Cajun seasoning over the vegetables and stir for about 30 seconds to bloom the spices.
  • Add the Rotel diced tomatoes, chicken broth, and smoked paprika. Bring to a gentle simmer.
  • Lower the heat and stir in the heavy cream. Simmer until slightly thickened.
  • Stir in the Parmesan cheese and spinach until melted and wilted.
  • Add the cooked pasta and sausage back into the skillet. Toss to combine, season with salt and black pepper, garnish with parsley, and serve warm.

Notes

You can swap the andouille sausage for smoked kielbasa or chicken sausage if needed.
For a lighter version, use half and half instead of heavy cream.
Leftovers keep well in the refrigerator for up to 3 days and reheat best on the stovetop with a splash of broth or cream.
This is one of those dinners that tastes even better when shared, especially with little helpers stealing bites along the way.
