Whether you want to adjust the protein, add more vegetables, or dial up the spice, this recipe serves as an excellent foundation for your culinary creativity.
Essential Ingredients for Instant Pot Rigatoni
Crafting this flavorful Instant Pot Rigatoni requires a selection of quality ingredients, most of which are likely already in your pantry. Here’s what you’ll need to create this amazing one-pot meal:
- Italian Sausage: The star of the show! You can use your favorite ground Italian sausage, whether it’s turkey, chicken, or pork. Opt for mild, medium, or hot based on your preference for spice. If you’re looking for a shortcut, pre-cooked sliced Italian chicken sausage brands like Al Fresco or Aidells also work wonderfully, just be sure to adjust cooking times slightly as they only need to be heated through. For an even more authentic taste, consider making your own Homemade Italian Sausage.
- Aromatics: A classic foundation for any great Italian sauce. Sautéing a finely minced yellow onion and fresh garlic alongside the sausage creates a rich, fragrant base that deeply flavors the pasta sauce. These simple ingredients are crucial for building the complex taste profile of this dish.
- Dry White Wine: While not strictly essential, a dry white wine (like Chardonnay or Pinot Grigio) is highly recommended for deglazing the pot. It adds a bright, acidic note that beautifully contrasts with the richness of the Italian sausage, elevating the overall flavor profile. If you prefer to omit alcohol, an equal amount of additional chicken stock will work perfectly as a substitute.
- Chicken Stock: The primary liquid for cooking the pasta. Always choose a low-sodium variety to better control the seasoning of your dish. Homemade chicken stock will provide the best flavor, but your favorite store-bought brand or even Instant Pot chicken stock will be excellent.
- Seasonings: Given the robust flavor from the Italian sausage and seasoned diced tomatoes, this dish requires minimal additional seasoning. A good quality Italian seasoning blend, salt, and freshly ground black pepper are essential. For a subtle kick, a pinch of crushed red pepper flakes can be added, making the dish more dynamic without overpowering the other flavors.
- Pasta: Rigatoni is an excellent choice for this recipe due to its hearty shape and ridges, which are perfect for capturing and holding the thick sauce. When selecting pasta for the Instant Pot, look for varieties that typically cook between 10-12 minutes on the stovetop. Other suitable options include medium shells, corkscrew noodles (fusilli), ziti, or bow-tie noodles (farfalle). The key is to choose a pasta that stands up well to pressure cooking without becoming overly soft.
- To Finish: Just before serving, stir in fresh baby spinach leaves and grated Parmesan cheese. The residual heat from the pasta will quickly wilt the spinach, adding a fresh burst of color and nutrients, while the Parmesan cheese melts into the sauce, contributing a creamy, salty finish.
How to Make the Best Instant Pot Rigatoni
Achieving perfect results with Instant Pot pasta is surprisingly simple once you understand a few key techniques. Follow these detailed steps to ensure your rigatoni is cooked to perfection every time. The precise ingredient quantities and comprehensive instructions can be found in the recipe card towards the bottom of this post.
Sauté the Sausage and Aromatics
Begin by activating the “Sauté” function on your Instant Pot. Add a teaspoon of extra virgin olive oil to the inner pot and allow it to heat for a brief moment. Once shimmering, add your ground Italian sausage along with the minced yellow onion. Use a wooden spoon or spatula to break up the sausage into small, uniform pieces as it cooks. Continue sautéing until the sausage is thoroughly browned and the onions have softened and become translucent. This browning step is crucial for developing deep, savory flavors. Next, add the minced garlic and cook for just 30-60 seconds until fragrant; be careful not to burn it. If there is any excess grease accumulated in the pot, carefully drain it off before proceeding to the next step, then return the inner pot to the pressure cooker base.
Deglaze the Inner Pot with Wine
After sautéing, it’s essential to deglaze the inner pot. This process involves adding a liquid to loosen any browned bits (fond) that may have stuck to the bottom of the pot. These bits are packed with flavor, and scraping them up will enrich your sauce while also preventing a “burn notice” during pressure cooking. Pour in the dry white wine (or additional chicken stock if you’re omitting wine) and use a wooden spoon or a sturdy spatula to gently scrape the bottom of the pot. Allow the wine to simmer for a minute or two, reducing slightly and dissolving all the flavorful browned remnants. Once deglazed, press “Cancel” to turn off the sauté function.
Layer the Ingredients Carefully
The layering of ingredients is a critical step for successful Instant Pot pasta, preventing clumping and ensuring even cooking. First, add the chicken stock, Italian seasoning, and crushed red pepper flakes (if using) to the pot with the sausage and wine mixture, stirring everything to combine evenly. Next, add the dried rigatoni noodles. Gently push them down into the broth until they are mostly submerged in the liquid. Finally, pour the undrained diced tomatoes directly on top of the pasta. This is important: Do NOT stir the tomatoes into the pasta or broth! Layering them on top helps prevent the dreaded “burn notice” as the denser tomatoes cook without direct contact with the heating element, allowing the pasta to cook properly in the liquid below.
Pressure Cook with Precise Timing
Precision is paramount when cooking pasta in the Instant Pot. For consistently al dente results, you should set the cooking time to exactly half the lowest suggested cooking time listed on the pasta box. For most rigatoni brands, this typically means cooking for 6 minutes on high pressure. Secure the lid on your Instant Pot, ensure the venting knob is in the “Sealing” position, and select the “Pressure Cook” or “Manual” setting for 6 minutes. Once the cooking time has elapsed, allow the pressure to naturally release for exactly 5 minutes. This brief natural release helps prevent foaming and ensures the pasta finishes cooking perfectly. After 5 minutes, carefully perform a quick release of any remaining pressure by moving the vent knob to the “Venting” position. Once the float valve drops, it’s safe to open the lid.
Add Spinach and Cheese for a Fresh Finish
With the pressure released and the lid safely removed, your Instant Pot Rigatoni is almost ready! Now, it’s time to add a burst of freshness and creamy richness. Stir in the fresh baby spinach leaves and grated Parmesan cheese. The residual heat from the pasta and sauce will quickly wilt the spinach, integrating its subtle flavor and vibrant color into the dish. Stir everything gently until well combined. For the best results, place the lid back on the inner pot for just 2-3 minutes to allow the spinach to fully wilt without overcooking the pasta. This step also allows the flavors to meld beautifully. Once the spinach is tender-crisp, your delicious Instant Pot Rigatoni is ready to serve!
Serving Suggestions for Instant Pot Rigatoni
This Instant Pot Rigatoni with Italian Sausage is a hearty and complete meal on its own, but it truly shines when paired with a few complementary sides. I highly recommend serving it just as you would serve other Italian comfort classics like Baked Ravioli or Crockpot Ziti. A warm, crusty slice of homemade garlic bread or garlic knots is practically mandatory for soaking up every last drop of the rich, savory sauce. To add a fresh, vibrant contrast and round out your meal, consider serving a simple green salad. Since this recipe uses fresh spinach, it’s a great excuse to utilize any leftover spinach in a delightful salad like a Spinach Bacon Salad, a light and fruity Strawberry Spinach Salad, or a creamy Spinach Avocado Salad. For a heartier side, roasted broccoli or asparagus would also complement the dish beautifully. And don’t forget an extra sprinkle of freshly grated Parmesan cheese and a drizzle of good olive oil at the table!
Substitutions and Modifications
One of the many strengths of this Instant Pot Rigatoni recipe is its adaptability. Feel free to customize it to suit your tastes, dietary needs, or whatever ingredients you have on hand. Here are some popular substitutions and modifications:
- Omit the Wine: If you prefer to cook without alcohol, simply replace the dry white wine with an equal amount of additional low-sodium chicken stock. The dish will still be incredibly flavorful.
- No Italian-Seasoned Tomatoes? No problem! If you only have regular diced tomatoes, you can easily replicate the seasoned flavor. Just add an additional 1 teaspoon of minced garlic and 2 teaspoons of Italian seasoning to the pot along with the chicken stock and other seasonings before pressure cooking.
- Gluten-Free Option: For a gluten-free version, I have consistently found that the Barilla brand of gluten-free pasta yields the best results in the Instant Pot. Other brands tend to release too much starch, which can affect the sauce consistency. Always follow the half-the-box-time rule for gluten-free pasta as well.
- Control the Spice Level: The crushed red pepper flakes add a pleasant warmth, but they are entirely optional. Feel free to omit them for a milder dish, or increase the amount to ½ teaspoon or more if you love extra heat.
- Dairy-Free Option: To make this recipe dairy-free, simply omit the grated Parmesan cheese at the end. Additionally, ensure that your chosen brand of Italian sausage is dairy-free, as some varieties may contain added cheese.
- Extra Cheesy Sausage Pasta: For cheese lovers, enhance the creaminess and indulgence by adding up to 2 cups of shredded mozzarella cheese to the pressure-cooked pasta when you stir in the spinach. The melting mozzarella will create an even richer, gooier sauce.
- Add More Veggies: Feel free to toss in other quick-cooking vegetables during the last few minutes of the sauté phase or even on top of the pasta before pressure cooking. Sliced mushrooms, bell peppers, or zucchini would be excellent additions.
Storage Instructions for Leftovers
This Instant Pot Rigatoni is so delicious, you might not have many leftovers! But if you do, it stores and reheats beautifully, making it perfect for meal prep.
- Refrigerate: Allow the pasta to cool slightly to room temperature before storing. Transfer it to an airtight container and store it in the refrigerator for up to 3 days. This ensures the pasta remains fresh and prevents bacterial growth.
- Freeze: For longer storage, this pasta freezes exceptionally well. Once the pasta has cooled completely, transfer it to a freezer-safe container or individual freezer-safe portions. Ensure the container is tightly sealed to prevent freezer burn. You can freeze the leftovers for up to 3 months. Thawing overnight in the refrigerator is recommended before reheating.
- Reheat: If frozen, allow the pasta to defrost in the refrigerator overnight. For reheating, place the desired portion of pasta in a heat-safe bowl. To prevent the pasta from drying out, add a tablespoon or two of water or chicken stock. Cover the bowl loosely with a moistened paper towel (this creates steam and keeps the pasta tender). Heat in the microwave in 1-minute intervals, stirring gently between each interval, until the pasta is warmed through to your desired temperature. Alternatively, you can reheat it gently on the stovetop over low heat, adding a splash of liquid as needed.

Notes
Cooking Time: Set the cooking time for HALF the suggested cooking time on the box of pasta you opted to use, which would almost always be 5 minutes for rigatoni. Once the cooking time has elapsed, let the pressure release for 5 minutes regardless of the type of pasta used. Then do a quick release of any remaining pressure.
Rigatoni: While I often opt for rigatoni in this recipe, medium shells, corkscrew noodles, ziti, or bow-tie noodles are all suitable for this recipe.
Sausage: Use your favorite turkey, chicken, or pork ground Italian sausage for this recipe. You can even use sliced precooked Italian chicken sausage, like al fresco or aidells.
Wine: Use a dry white wine like Pinot Grigio, Chardonnay, or Riesling. Or use additional chicken stock in place of the wine.
No Italian-Seasoned Tomatoes? If you only have regular diced tomatoes, use an additional 1 teaspoon of minced garlic and 2 teaspoons of Italian seasoning to season the pasta before pressure cooking.
Cheesy Sausage Pasta: Add up to 2 cups of shredded mozzarella cheese to the pressure-cooked pasta when adding the spinach for a cheesy finish.
Storage: Store leftover pasta in an airtight container for up to 3 days in the refrigerator. Alternatively, you can freeze the pasta in a freezer-safe container for up to 3 months. Reheat in a heat-safe dish covered with a damp paper towel in 60-second intervals until warmed through.
