What Makes This Recipe Great
We’ve all been there: you want a gourmet, “spent-all-Sunday-in-the-kitchen” kind of dinner, but you only have 30 minutes and a single clean pot.
Enter the One-Pot Caramelized Onion and Sausage Pasta. This recipe is the bridge between weeknight convenience and restaurant-quality flavor. By using chicken bone broth to cook the pasta directly in the pan, we create a starchy, velvety sauce that clings to every rigatoni tube. Plus, the sweetness of the onions paired with savory sausage is a match made in culinary heaven.
Ingredient Information
- Sausage – use any type of sausage you enjoy, spicy, hot they all work
- Sweet Onion– Thinly sliced and caramelized for natural sweetness
- Minced Garlic
- Bone Broth– Adds richness and nutrients to the “sauce.”
- Pasta – any size an shape will work, rigatoni is our favorite
- Asparagus– Adds a fresh, snappy crunch to balance the richness
- Heavy Cream– Just enough to make it luxurious without being heavy.
- Parmesan– Use freshly grated Parmesan if possible; it melts much smoother than the bottled stuff.
- Salt & Pepper– measure both of these with the heart
Why You’ll Love This One-Pot Pasta
- Maximum Flavor, Minimum Cleanup: By cooking the pasta directly in bone broth, every noodle absorbs the savory goodness, and you only have one pot to scrub.
- The Flavor Foundation: Sautéing the onions in the rendered sausage fat creates a rich, “liquid gold” base that makes the sauce taste like it simmered for hours.
- Perfectly Balanced: The sweetness of the caramelized onions and the richness of the parmesan are perfectly cut by the fresh, earthy crunch of the asparagus.
- Protein-Packed: Using chicken bone broth instead of water adds extra protein and a silkier texture to the final sauce.

One Pot Caramelized Onion & Sausage Pasta
Ingredients
- 1 lb sausage
- 1 sweet onion, thinly sliced
- 2 tbsp minced garlic
- 4 cups chicken bone broth
- 1 lb pasta, i like rigatoni but use your favorite!
- 1 bunch asparagus chopped
- 2 tbsp heavy cream
- ½ cup grated parmesan cheese
- Salt and pepper to taste
Instructions
- Set a large pot or Dutch oven over medium-high heat. Add the sausage (if using links, remove the casings first). Break it apart with a wooden spoon and 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.
- Turn the heat down to medium. Add your thinly sliced onions to the sausage fat. Cook them low and slow, stirring occasionally, for about 12–15 minutes.
- Add the minced garlic to the onions and cook for just 1 minute until fragrant. Pour in a splash of the chicken bone broth to scrape up any brown bits from the bottom of the pot.
- Add the rest of the chicken bone broth and bring it to a rolling boil. Stir in your pasta. Reduce the heat to medium-low, cover, and let it simmer. Set your timer for 13 minutes.
- When there are about 5 minutes left on the timer, toss the chopped asparagus right on top of the pasta. Put the lid back on to let them steam-cook until tender-crisp.
- Once the pasta is cooked and most of the liquid has been absorbed (it should look saucy, not soupy), turn off the heat. Stir in the heavy cream and parmesan cheese. Then add in the sausage and season with salt and pepper to taste.
