- 12 ounces Italian-style chicken sausage links, casings removed
- 2 garlic cloves, minced
- 3 cups chopped fresh spinach

How to Make Instant Pot Pasta with Italian Sausage
Step 1: Prepare the Ingredients
Before turning on the pressure cooker, chop the onion and bell peppers, mince the garlic, and roughly chop the spinach. Remove the casings from the chicken sausage and break the links into manageable pieces.
Measure the pasta, sauce, water, herbs, and cheese so everything is ready to add as needed.
Step 2: Sauté the Vegetables
Select the Sauté function on your Instant Pot and pour in the olive oil. Once the oil is hot, add the chopped onion and sliced bell peppers. Cook for approximately 3 to 4 minutes, stirring occasionally, until the vegetables begin to soften.
Add the sausage and break it into smaller pieces with a wooden spoon. Continue cooking for 4 to 5 minutes, stirring regularly, until the meat is lightly browned. Stir in the minced garlic and cook for another 1 to 2 minutes, taking care not to burn it.
Step 3: Add the Pasta and Sauce
Pour the marinara sauce and water into the pot. Add the penne, chopped spinach, fresh basil, and Italian seasoning. Stir everything together, making sure the pasta is distributed throughout the liquid and not stuck to the bottom.
Cancel the Sauté function and check that the ingredients are evenly combined. Properly distributing the pasta in the liquid helps it cook more consistently under pressure.
Step 4: Pressure Cook
Secure the Instant Pot lid and set the pressure valve according to the manufacturer’s instructions. Select High Pressure and set the cooking time to 5 minutes.
Allow approximately 10 to 15 minutes for the cooker to reach pressure. Once the cooking cycle begins, the pasta and other ingredients will cook together, allowing the flavors to blend into a rich, tomato-based sauce.
Step 5: Release the Pressure
When the cooking cycle is complete, allow the pressure to release naturally for 5 minutes. Afterward, carefully switch to quick release to release any remaining pressure.
Keep your hands and face away from the steam valve, and follow the manufacturer’s safety instructions.
Once the pressure indicator has dropped, unlock and remove the lid. Stir the pasta gently to distribute the sausage, vegetables, and sauce evenly.
Step 6: Add the Cheese and Serve
Sprinkle ½ cup of shredded Italian cheese blend over the hot pasta and stir until it melts into the sauce. The cheese adds a creamy texture and a savory finish without requiring a separate sauce preparation.
Divide the pasta among four serving bowls and sprinkle the remaining cheese over each portion. Serve immediately while the pasta is warm and the cheese is still melted.
Helpful Cooking Tips
Adjust the Herb Seasonings
Italian seasoning and fresh basil give this pasta its characteristic aromatic flavor. However, using both in generous quantities can sometimes overpower the sausage and marinara sauce.
For a milder result, reduce the Italian seasoning to 1 teaspoon and leave out the basil if preferred. You can always add more herbs after cooking to suit your taste.
Choose the Right Pasta
Penne works well because its short, sturdy shape holds the sauce and pairs nicely with the sausage and vegetables. Other short pasta varieties may also be suitable, but cooking times and liquid absorption can vary.
If changing the pasta shape, check its recommended pressure-cooking time and adjust carefully to avoid overcooking.
Avoid a Burn Warning
Before sealing the cooker, make sure there are no large amounts of pasta or thick sauce stuck to the bottom. The ingredients should be distributed evenly, with sufficient liquid around the pasta.
Follow your pressure cooker’s instructions for layering and stirring to help prevent scorching.
Customize the Protein
Italian chicken sausage provides a savory flavor while keeping the meal convenient to prepare. Traditional Italian pork sausage can be used instead if preferred.
If the sausage is particularly fatty, drain excess grease after browning before adding the other ingredients.
Add More Vegetables
The recipe already includes spinach, onion, and bell peppers, but you can adjust the vegetable combination to suit your preferences.
Keep in mind that vegetables release moisture during cooking, so adding substantial quantities may change the consistency of the sauce.
Serving Suggestions
Serve this pasta in warm bowls with an additional sprinkle of Italian cheese. A simple green salad with a light vinaigrette offers a refreshing contrast to the rich tomato sauce.
Garlic bread or toasted crusty bread is another suitable accompaniment for soaking up any extra sauce.
For a casual family meal, place the Instant Pot pasta in a large serving dish and allow everyone to add their preferred amount of cheese. Serve it as soon as possible after cooking to enjoy the best texture.
Variations to Try
- Creamier pasta: Stir in a small amount of cream or cream cheese after pressure cooking for a richer sauce.
- Spicier sausage pasta: Add crushed red pepper flakes to the sautéed sausage for extra heat.
- Pork sausage version: Replace the chicken sausage with Italian pork sausage and drain any excess fat before adding the sauce.
- Extra cheesy finish: Sprinkle additional shredded Italian cheese over the finished pasta and allow the residual heat to melt it.
- Different pasta shapes: Try another short pasta variety that holds sauce well, adjusting the pressure-cooking time as necessary.
