Ingredients

Main Ingredients

  • 1 lb sausage (casings removed if using links)
  • 1 sweet onion, thinly sliced
  • 2 tbsp minced garlic
  • 4 cups chicken bone broth
  • 1 lb pasta (rigatoni or your favorite type)
  • 1 bunch asparagus, chopped
  • 2 tbsp heavy cream
  • ½ cup grated parmesan cheese
  • Salt and pepper to taste

Instructions

  1. Cook the Sausage: Set a large pot or Dutch oven over medium-high heat. Add the sausage, breaking it apart with a wooden spoon. Cook until browned and crispy, about 5–7 minutes. Use a slotted spoon to remove the sausage and set it aside, leaving the rendered fat in the pot.
  2. Caramelize Onions: Reduce the heat to medium. Add the thinly sliced onions to the sausage fat in the pot. Cook low and slow, stirring occasionally, for 12–15 minutes until golden and caramelized.
  3. Sauté Garlic: Add the minced garlic to the caramelized onions and cook for 1 minute until fragrant. Pour in a splash of chicken bone broth to deglaze the pot, scraping up any browned bits from the bottom.
  4. Cook Pasta: Add the remaining chicken bone broth and bring it to a rolling boil. Stir in the pasta and reduce heat to medium-low. Cover and let simmer for 13 minutes.
  5. Add Asparagus: With about 5 minutes remaining on the timer, scatter the chopped asparagus over the pasta. Replace the lid to steam-cook the asparagus until tender-crisp.
  6. Finish the Dish: Once the pasta is cooked and the liquid has mostly absorbed, turn off the heat. Stir in the heavy cream and grated parmesan cheese, then fold in the cooked sausage. Season with salt and pepper to taste before serving.

Notes

  • If using sausage links, be sure to remove the casings before cooking for easier browning.
  • Use bone broth for richer flavor, but chicken broth or stock can substitute if needed.
  • Feel free to swap rigatoni with penne, ziti, or any sturdy pasta that holds sauce well.
  • Adjust the cream and parmesan amount to your preference for more or less richness.
  • Leftovers store well in the refrigerator for up to 3 days and reheat gently with a splash of broth or cream.
