Instant Pot Italian Sausage Pasta

Some nights just call for a warm, filling meal that doesn't take a ton of time. This Instant Pot Italian Sausage Pasta delivers exactly that, a one-pot pasta made with Italian-style pork sausage (seasoned with fennel and garlic), tomato sauce, and pasta cooked together under pressure.

You get rich, meaty sausage, tender pasta, and a creamy tomato-based sauce-all cooked together with almost no cleanup.

Save for Later!

We first made this on a rushed weeknight and it instantly became a regular. Everything goes into the pot, and about 30 minutes later, it's dinner time.

You're not juggling pans or waiting for water to boil. Just hit pressure cook, stir in a little cream at the end, and it's ready to serve.

Why This Recipe Works in the Instant Pot

Cooking pasta and sausage together isn't new, but the Instant Pot makes it faster and easier; a similar Instant Pot chicken noodle soup for weeknights shows the same technique.

• Everything cooks in one place, so flavors come together better under pressure (pressure cooking concentrates flavors by trapping steam and circulating juices).
• The sausage gets deeply browned, adding more flavor to the sauce.
• No need to drain pasta, which helps the sauce cling better with the starch.

You'll end up with pasta that's saucy and flavorful, not watery or bland.

Save for Later!

• Italian sausage - Mild or spicy works. Browning it adds depth.
• Pasta - Short types like penne or rigatoni hold up best under pressure.
• Garlic and onion - Build the savory foundation for the sauce.
• Crushed tomatoes - Adds body and a little acidity.
• Heavy cream or half-and-half - Stirred in at the end to smooth it out.

A little salt, pepper, and maybe red pepper flakes finish it off.

How to Make It - Step by Step

Here's how it all comes together without needing separate pots or pans.

• Brown the sausage
  Set the Instant Pot to sauté and cook sausage until browned. Break it up with a wooden spoon. Remove excess fat if needed.
• Add aromatics and tomatoes
  Stir in chopped onions and garlic. Cook until softened. Add crushed tomatoes and seasonings, scraping the bottom to loosen browned bits.
• Add pasta and water
  Pour in pasta and enough water or broth to just cover. Do not stir. Just gently press the pasta into the liquid.
• Pressure cook
  Seal the lid and set to HIGH pressure for 5-6 minutes, depending on pasta type. Quick release the pressure once done.
• Finish with cream
  Stir in cream or half-and-half while it's still hot. Let it sit for a few minutes to thicken.
• Taste and serve
  Adjust salt and pepper. Serve hot with a sprinkle of Parmesan or chopped parsley if desired.

Storage and Reheat Tips

You'll likely have leftovers-and they hold up well for a few days.

• Fridge: Store in an airtight container for up to 4 days.
• Reheat: Add a splash of broth or milk before microwaving to keep it creamy.

Avoid freezing, as pasta can turn mushy after thawing.

Common Questions About This Recipe

Can I use another type of sausage?
Yes, chicken sausage or even ground beef works. Just adjust seasoning to fit the flavor.

Is this too spicy for kids?
Use mild sausage and skip red pepper flakes to keep it family-friendly.

Can I add vegetables?
Absolutely. Toss in spinach, bell peppers, or mushrooms before pressure cooking.

Will dairy curdle under pressure?
Add cream after pressure cooking, not before, to avoid curdling or separating.

For a bolder, seafood-forward dinner, try the spicy Cajun shrimp and sausage pasta, which pairs shrimp with smoked sausage in a peppery tomato-cream sauce. If you prefer a milder, cream-based option, the Instant Pot chicken Alfredo for creamy weeknights uses shredded or rotisserie chicken with a garlic-parmesan sauce.
