Ingredients

  

• 1 pound Italian sausage sweet or hot, casings removed if using links
• 1 medium onion diced
• 3 cloves garlic minced
• 1 red bell pepper diced (optional)
• 2 teaspoons Italian seasoning
• 1/2 teaspoon red pepper flakes optional, adjust to taste
• 1 can 14.5 oz diced tomatoes, undrained
• 3 cups chicken broth
• 1/2 cup heavy cream or half-and-half for a lighter option
• 12 oz pasta penne, rotini, or farfalle work best
• Salt and black pepper to taste
• 1 cup shredded cheese mozzarella, Parmesan, or an Italian blend
• 2 cups fresh spinach optional
• 2 tablespoons fresh basil chopped (optional)

Instructions

 

• Brown the sausage. Heat your pot or deep skillet over medium-high heat. Add the Italian sausage, breaking it apart with a wooden spoon as it cooks until nicely browned, about 5-7 minutes.
• Add aromatics. Reduce heat to medium and add diced onion to the pot with the sausage. Cook for 2-3 minutes until onion begins to soften. Add garlic and bell pepper (if using) and cook for another minute until fragrant.
• Season the base. Stir in Italian seasoning and red pepper flakes (if using). Cook for 30 seconds to bloom the spices, which releases their flavors.
• Build the sauce. Add diced tomatoes with their juice, stirring to combine and scraping any browned bits from the bottom of the pot (that's flavor gold!).
• Add liquids and pasta. Pour in the chicken broth and heavy cream, stirring to combine. Add the dry pasta and stir well to ensure it's submerged in liquid.
• Bring to a perfect simmer. Increase heat to medium-high and bring the mixture to a boil. Once boiling, reduce heat to maintain a gentle simmer. Cover the pot.
• Cook pasta to perfection. Simmer covered for about 10-12 minutes, stirring occasionally to prevent sticking. The pasta should be al dente and most of the liquid absorbed, but some sauce should remain. If it seems too dry, add a splash more broth; if too wet, simmer uncovered for a few more minutes.
• Final touches. Remove from heat and stir in the shredded cheese until melted. If using spinach, stir it in now to wilt from the residual heat.
• Rest briefly. Let the pot stand covered for 2-3 minutes to allow the sauce to thicken slightly and flavors to meld.
• Serve with flair. Garnish with fresh basil if using, and serve directly from the pot for true one-pot meal simplicity.

Notes

• Pasta selection matters. Medium-sized shapes with ridges or curves (like penne, rotini, farfalle, or shells) hold sauce best and cook most evenly in one-pot methods.
• Keep it moving. Stir occasionally throughout cooking to prevent pasta from sticking to the bottom, especially toward the end.
• Watch your liquid ratio. Different pasta shapes absorb liquid differently. If the pasta isn’t yet tender but the liquid is mostly absorbed, add another 1/4 cup of broth or water.
• For a spicier kick, use hot Italian sausage and/or increase the red pepper flakes.
• Make it creamier by adding 2 ounces of cream cheese along with the heavy cream.
• This reheats beautifully for leftovers. Store in an airtight container in the refrigerator for up to 3 days. When reheating, add a splash of water or broth to loosen the sauce.
• Time-saving tip: Use pre-chopped vegetables from the grocery store produce section to cut prep time even further.

Common Mistakes to Avoid

• Using too small a pot. The pasta needs room to expand, and the liquid needs space to circulate. Use at least a 4-quart capacity pot.
• Cooking at too high a heat. A vigorous boil can cause the pasta to break down and the sauce to reduce too quickly. Maintain a gentle simmer.
• Not stirring occasionally. This isn’t a set-it-and-forget-it recipe. Regular (but not constant) stirring prevents sticking and ensures even cooking.
• Adding the cream too early. Heavy cream can curdle if boiled too long. Adding it with the broth works in this recipe because the pasta quickly absorbs most of the liquid.
• Overcooking the pasta. Check it at the minimum cooking time. Remember it will continue to absorb liquid as it stands.
• Using pre-grated cheese with anti-caking agents. These can prevent proper melting. Grate your own for the creamiest results.
• Not letting it rest. Those few minutes of standing time allow the sauce to thicken to the perfect consistency.

Alternatives & Substitutions

• Protein options: Substitute chicken sausage, ground turkey, sliced smoked sausage, or even plant-based sausage. For seafood lovers, add peeled shrimp during the last 3-4 minutes of cooking.
• Pasta variations: Any medium-sized pasta works; for whole grain options, you may need to add cooking time and additional liquid.
• Dairy alternatives: Coconut cream or cashew cream can replace heavy cream for a dairy-free version. Skip the cheese or use a plant-based alternative.
• Vegetable swaps: Mushrooms, zucchini, peas, broccoli florets, or kale can replace or supplement the bell pepper and spinach. Add firmer vegetables earlier and tender ones later in the cooking process.
• Spice it up: Add 1 tablespoon of cajun seasoning instead of Italian for a spicy twist.
• Broth options: Use vegetable broth for a vegetarian version (with plant-based sausage), or beef broth for a richer flavor.
• Lighter version: Use half-and-half instead of heavy cream, reduce cheese to 1/2 cup, and use chicken or turkey sausage.
• Extra indulgent: Add 1/4 cup sun-dried tomatoes along with the canned tomatoes for intense flavor, or stir in 2 tablespoons of pesto at the end.

FAQs

Can I use a different type of pasta?

Yes! Medium-sized shapes like rotini, penne, ziti, or shells work best in one-pot recipes. Long pastas like spaghetti or fettuccine can work but require more attention to ensure they’re submerged and cook evenly. Pasta cooking times may vary, so check for doneness as you go.

What if I don’t have heavy cream?

Several options work well: half-and-half for a lighter version, cream cheese (2-3 oz) stirred in at the end for thickness, or even a splash of milk mixed with a tablespoon of butter. In a pinch, you can even skip it entirely and just use extra broth, though the sauce won’t be as creamy.

Can I make this vegetarian?

Absolutely! Use plant-based sausage or omit it entirely and add extra vegetables like mushrooms, zucchini, or eggplant. Use vegetable broth instead of chicken broth, and consider adding a can of drained white beans for protein.

How do I store and reheat leftovers?

Store leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, add a splash of water or broth to loosen the sauce, as the pasta will continue to absorb liquid as it sits. Reheat gently in a covered pot on the stove or in the microwave at 50% power.

Can I prep any components ahead of time?

You can brown the sausage and sauté the vegetables up to a day ahead. Store in the refrigerator, then pick up from step 4 when ready to cook, allowing a few extra minutes for the refrigerated ingredients to heat through.

Would this work in a slow cooker or Instant Pot?

This recipe adapts well to both! For Instant Pot: Use the sauté function for steps 1-3, then add remaining ingredients except cream, cheese, and spinach. Cook on high pressure for half the recommended pasta cooking time. Quick release, stir in cream, cheese, and spinach. For slow cooker: Brown sausage and vegetables on the stove, transfer to slow cooker with broth and tomatoes (no pasta yet). Cook on low for 3-4 hours, then stir in pasta and cook on high for about 30 minutes until pasta is tender. Add cream, cheese, and spinach in the last 5 minutes.

What sides go well with this dish?

This is a complete meal on its own, but a simple green salad or garlic bread pairs wonderfully. For a lighter accompaniment, try roasted asparagus or a quick cucumber salad.
