This method transforms weeknight dinner with minimal effort and maximum flavor. The Instant Pot handles everything in one pot, eliminating the need for multiple pans and constant stirring.
Ground beef, rigatoni, and rich tomato sauce cook together under pressure, allowing the pasta to absorb the meaty flavors while maintaining a perfect al dente texture. No pre-cooking required—just layer and cook.
The result is a hearty, restaurant-quality dish with tender pasta, savory sauce, and well-seasoned beef. Every bite delivers the comforting depth of a slow-simmered meal in a fraction of the time.
Cleanup is just as simple as the cooking process. This is the kind of meal that makes busy evenings feel effortless.
Ingredients for Instant Pot Rigatoni
Pantry staples meet fresh ingredients for a hearty one-pot meal with deep flavor.
| Ingredient | Amount | Notes |
|---|---|---|
| Ground Beef 🥩 | 1 lb | 80/20 lean-to-fat ratio preferred |
| Rigatoni Pasta 🍝 | 12 oz | Dry, uncooked pasta |
| Crushed Tomatoes 🍅 | 28 oz | One can, San Marzano preferred |
| Tomato Paste 🍅 | 2 tbsp | Double-concentrated preferred |
| Yellow Onion 🧅 | 1 whole | Medium-sized, finely diced |
| Garlic Cloves 🧄 | 4 cloves | Minced for even distribution |
| Beef Broth 🥣 | 2 cups | Low-sodium preferred |
| Dried Oregano 🌿 | 1 tsp | Mediterranean variety preferred |
| Dried Basil 🍃 | 1 tsp | Crushed for better infusion |
| Kosher Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground for best flavor |
| Olive Oil 🫒 | 2 tbsp | Extra-virgin for sautéing |
| Parmesan Cheese 🧀 | ½ cup | Freshly grated from wedge |
| Water 💧 | 1 ½ cups | For pressure cooking balance |
The ground beef is non-negotiable here. 80/20 lean-to-fat ratio gives you the best flavor and texture without excessive grease. Whole Foods or Costco have excellent options, but any supermarket ground chuck works. For the tomatoes, San Marzano crushed tomatoes are the gold standard—look for the DOP certification on the can if you want to be precise (worth the extra minute).
No rigatoni? Penne or ziti work just as well—any short, sturdy pasta that holds sauce. Out of beef broth? Chicken broth in a pinch, but beef adds that rich depth. The oregano and basil can be fresh at triple the amount if you’ve got them growing. For extra richness, stir in a splash of heavy cream at the end (don’t skip this part).
Leftovers keep beautifully for 4-5 days in the fridge, and the flavors actually improve. Freezes well for 3 months—portion into airtight containers first. Always let it cool slightly before sealing to avoid soggy pasta.

Step-by-Step Instructions for Instant Pot Rigatoni
Everything comes together in one pot with precise timing for perfect results.
Step 1: Sauté the Aromatics and Brown the Ground Beef
Set your Instant Pot to the Sauté function on Normal/Medium heat. Add the 2 tbsp Olive Oil and let it heat for 30 seconds until shimmering. Add the finely diced Yellow Onion and cook for 3-4 minutes until it becomes translucent and starts to soften.
Push the onion to one side and add the 1 lb Ground Beef, breaking it up with a wooden spoon. Cook for 5-6 minutes until the beef is fully browned and no pink remains. This step builds a flavor foundation for your sauce.
Stir in the minced Garlic Cloves and cook for 30 seconds until fragrant. Be careful not to let the garlic burn, as it will turn bitter. The mixture should be sizzling with a rich, meaty aroma.
Step 2: Build the Sauce Base
Add the 2 tbsp Tomato Paste to the beef mixture and stir well, cooking for 1-2 minutes until it deepens in color. This step enhances the umami flavor of your sauce.
Pour in the 28 oz Crushed Tomatoes, 2 cups Beef Broth, 1.5 cups Water, 1 tsp Dried Oregano, 1 tsp Dried Basil, 1 tsp Kosher Salt, and 0.5 tsp Black Pepper. Stir everything together, scraping the bottom of the pot to deglaze and release any browned bits.
These browned bits, or fond, are packed with flavor and will dissolve into the sauce, creating a rich, complex base.
Step 3: Pressure Cook the Rigatoni
Add the 12 oz Rigatoni Pasta to the pot, pressing it down gently into the sauce so it is mostly submerged. Secure the lid, set the valve to Sealing, and cook on High Pressure for 5 minutes.
The pasta will cook directly in the sauce, absorbing the flavors as it softens. This one-pot method ensures every bite is infused with the rich, meaty tomato base.
Once the cooking time is complete, allow the pressure to release naturally for 5 minutes, then perform a quick release to open the lid.
Step 4: Finish and Serve
Stir the rigatoni thoroughly to distribute the pasta and sauce evenly. The pasta should be al dente and coated in a thick, hearty sauce. If the sauce is too thick, stir in a splash of the Beef Broth or Water to reach your desired consistency.
Let the dish sit for 2-3 minutes to allow the flavors to meld together. This short rest ensures the pasta absorbs any remaining liquid, creating a perfectly balanced texture.
Serve hot, topped with the 0.5 cup Parmesan Cheese, freshly grated for the best texture and flavor. The cheese will melt slightly into the hot pasta, adding a creamy finish.
Pro Tips For Making Instant Pot Rigatoni
- Brown the Beef Well: Don’t rush the browning step—cook the ground beef until it’s deeply browned, not just gray. I learned this the hard way after ending up with bland sauce.
- Cut the Onions Small: Finely dice the yellow onion so it practically melts into the sauce. Big chunks just get in the way of the rigatoni.
- Skip the Pre-Boil: Add the dry rigatoni straight to the Instant Pot—no need to pre-cook. It absorbs the flavors better and saves a dirty pot.
- Stir the Tomato Paste: After adding the tomato paste, cook it for 1-2 minutes while stirring to deepen its flavor before adding liquids. Sounds weird, but it works.
Serving Suggestions for This instant pot rigatoni
Garnish Like a Pro
Fresh Parmesan Cheese is non-negotiable for serving—I always grate it from a wedge right before adding. The texture and flavor are far superior to pre-grated. Sprinkle ¼ cup per serving for that perfect finish. 🧀
Add Fresh Herbs
A handful of fresh basil or parsley adds bright, herbaceous notes that cut through the richness. I tear 4-5 basil leaves per bowl just before serving. This small touch makes the dish feel restaurant-quality.
Side Salad Pairing
A simple green salad with a light vinaigrette balances the hearty pasta. I love baby arugula with lemon juice and olive oil. The peppery greens contrast beautifully with the savory rigatoni.
Garlic Bread Essential
No Italian meal is complete without garlic bread. Toast a baguette with butter, garlic, and parsley for 5 minutes at 375°F. It’s perfect for soaking up any leftover sauce.
Wine Match
A medium-bodied red wine like Chianti or Sangiovese pairs wonderfully. The acidity cuts through the richness of the beef and tomato sauce. I serve it slightly chilled for best results. 🍷
Family-Style Service
For gatherings, serve this directly from the Instant Pot liner. The deep dish makes it easy for everyone to help themselves. I always have extra Parmesan on the table for second helpings.

Frequently Asked Questions
Can I use a different pasta shape?
Yes! Penne or ziti work perfectly. Just keep the cooking time at 5 minutes on high pressure. Shorter shapes hold sauce well.
What if my pasta turns out mushy?
Overcooking or too much liquid causes this. Use exactly 1.5 cups water and release pressure after 5 minutes. Stir immediately to stop cooking.
Can I make this vegetarian?
Swap beef for 1 lb mushrooms or lentils. Sauté first, then follow the same steps. Use vegetable broth instead of beef.
How do I store leftovers?
Keep in an airtight container for 4-5 days in the fridge. Freeze for up to 3 months. Reheat with a splash of water.
