Instant Pot Sausage and Pasta Recipe: One-Pot Weeknight Feast

Busy weeknights demand simple solutions, and this one-pot meal delivers without compromise. I developed this recipe after too many evenings of takeout containers piling up, determined to create something hearty that cooks itself.

The Instant Pot handles everything: browning the sausage, cooking the pasta, and developing rich flavors all in the same pot. No straining, no extra dishes—just 30 minutes from start to finish with minimal hands-on time. The sausage infuses the pasta with savory depth.

What emerges is a restaurant-quality dish with tender pasta, perfectly cooked sausage, and a light broth that soaks into every bite. It’s the kind of meal that feels special but fits effortlessly into a weekday schedule.

Ideal for families or anyone craving comfort food without the fuss. Here’s how to make it.

Ingredients for Instant Pot Sausage and Pasta

One-pot convenience with restaurant-quality ingredients ready in 30 minutes flat.

The sausage is the foundation here. Johnsonville Italian (available at most supermarkets) offers consistent quality and flavor. For the broth, Swanson low-sodium provides a clean base without overpowering saltiness. The ditalini pasta absorbs the cooking liquid beautifully, but small shells or penne work just as well if that’s what’s in your pantry.

No Italian sausage? Ground pork with Italian seasoning gets you close. Swap ditalini for any short pasta—half the amount if using orzo. Fresh tomatoes can replace canned (about 3 medium), but canned guarantees consistent moisture. Heavy cream can be half-and-half, though the sauce will be slightly lighter. Skip the spinach? Kale or frozen peas add color and texture.

Store uncooked sausage in the fridge for up to 3 days or freeze for 2 months. The dish keeps well refrigerated for 4 days—the pasta absorbs more liquid over time. Reheat with a splash of broth to restore the creamy consistency.

Step-by-Step Instructions for Instant Pot Sausage and Pasta

This one-pot method streamlines everything while delivering maximum flavor with minimal cleanup.

Step 1: Brown the Italian Sausage and Aromatics

Set your Instant Pot to the sauté function on normal heat. Add the 1 tbsp olive oil and the 1 lb Italian Sausage with casings removed, breaking it into small pieces with a wooden spoon. Cook for 5-6 minutes until the sausage is browned and no longer pink.

Add the finely diced 1 whole Yellow Onion and cook for 3-4 minutes until it becomes translucent and fragrant. Stir in the minced 3 cloves Garlic Cloves, 1 tsp Dried Basil, 1 tsp Dried Oregano, 0.5 tsp Red Pepper Flakes, 1 tsp Salt, and 0.5 tsp Black Pepper. Cook for 30 seconds to bloom the spices.

Step 2: Deglaze and Add Remaining Ingredients

Pour in 0.5 cup of the 4 cups Chicken Broth to deglaze the pot, scraping up any browned bits from the bottom with a wooden spoon. This step prevents burning and incorporates all the flavorful fond into the dish.

Add the remaining 3.5 cups Chicken Broth, the 1 can Diced Tomatoes (with juice), and the 8 oz Ditalini Pasta. Stir well to combine, ensuring the pasta is submerged in the liquid. The liquid should just cover the pasta—if it doesn’t, add a splash more broth.

Step 3: Pressure Cook to Perfection

Secure the lid on the Instant Pot and set the valve to sealing. Cook on high pressure for 5 minutes. The pot will take 8-10 minutes to come to pressure before the timer begins.

Once the cooking time is complete, allow the pressure to release naturally for 5 minutes, then carefully switch the valve to venting to release any remaining pressure. The pasta should be al dente and the liquid mostly absorbed, with a slightly creamy consistency.

Step 4: Finish with Cream and Spinach

Stir in the 0.5 cup Heavy Cream and the 2 cups Spinach, pressing the spinach down into the liquid. Let it sit for 2-3 minutes until the spinach is fully wilted and the cream is evenly incorporated.

The sauce will thicken slightly as it cools. If it’s too thick, stir in a splash of warm water or additional broth. Taste and adjust seasoning with more Salt or Black Pepper if needed.

Step 5: Serve with Parmesan

Ladle the sausage and pasta into bowls and top each serving with a generous sprinkle of the 0.5 cup Parmesan Cheese. The cheese will melt slightly into the hot dish, adding a salty, nutty depth.

Serve immediately while hot, as the pasta will continue to absorb liquid as it sits. This dish is best enjoyed fresh, with a side of crusty bread to soak up any remaining sauce.

Troubleshooting Great instant pot sausage and pasta

Pasta Not Cooked

If your pasta comes out undercooked, it likely needs more liquid to finish cooking. Add ½ cup additional chicken broth, stir well, and pressure cook for another 2-3 minutes. I always ensure the pasta is fully submerged before sealing the lid. 💡

Burn Notice

A burn notice usually means food stuck to the bottom. Always deglaze thoroughly with ½ cup broth after browning. If you see the notice, release pressure, scrape the pot, and add 1 cup extra liquid before restarting.

Too Thick

If the sauce is overly thick after cooking, stir in ¼ to ½ cup warm broth or water until reaching your desired consistency. The pasta continues absorbing liquid as it sits, so I often add a splash right before serving.

Too Thin

For a thin, watery sauce, remove the lid and simmer on sauté mode for 3-5 minutes to reduce. Stir frequently to prevent sticking. A cornstarch slurry (1 tbsp cornstarch + 1 tbsp water) can also thicken it quickly.

Spinach Not Wilting

If the spinach remains tough, ensure it’s fully submerged in the hot liquid. Stir well, cover with the lid, and let sit for 2-3 minutes off heat. Fresh spinach wilts fast once properly incorporated.

Sausage Too Dry

Overcooked sausage can dry out. Brown just until no longer pink (5-6 minutes), then stop. The pressure cooking step finishes the cooking. For extra juiciness, I use 80/20 ground sausage instead of lean. ⚡
