Ingredients
- 12 oz (340 g) penne pasta (or any short pasta)
- 1 tablespoon olive oil
- 1 small yellow onion, diced
- 3 cloves garlic, minced
- 1 pound (450 g) ground Italian sausage (mild or spicy)
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1 teaspoon dried Italian seasoning
- 1/4 teaspoon crushed red pepper flakes (optional)
- 1 (24 oz/680 g) jar marinara sauce
- 3 cups (720 ml) low-sodium chicken broth
- 1/2 cup (120 ml) heavy cream
- 1 cup (100 g) shredded mozzarella cheese
- 1/4 cup (25 g) grated Parmesan cheese
- Fresh basil, chopped, for serving (optional)
Instructions
- Set your Instant Pot to the sauté function. Once hot, add olive oil, then the diced onion. Sauté for 2-3 minutes until softened.
- Add the minced garlic and cook for another 30 seconds until fragrant.
- Add the ground Italian sausage. Use a wooden spoon to break it up as it browns. Cook for 5-6 minutes, until no pink remains.
- Season with salt, black pepper, Italian seasoning, and red pepper flakes (if using). Stir well.
- Press ‘Cancel’ to stop sautéing. Pour in the marinara sauce and chicken broth. Stir to combine, scraping any browned bits from the bottom of the pot.
- Add the uncooked penne pasta. Gently press the pasta into the liquid but do not stir. This helps prevent a burn warning.
- Secure the Instant Pot lid and set the valve to ‘Sealing.’ Cook on high pressure for 5 minutes (it will take about 10 minutes to come to pressure).
- Once the timer beeps, allow a natural pressure release for 3 minutes, then carefully quick-release any remaining pressure.
- Open the lid and stir in the heavy cream. Add mozzarella and Parmesan cheeses, stirring until melted and creamy.
- Taste and adjust seasoning if needed. Serve hot, garnished with chopped fresh basil if desired.
Tips
- Pasta Choices: Short pastas like penne, rigatoni, or rotini hold up best in the Instant Pot. Long pastas (like spaghetti) may clump, but you can break them in half and fan them out for even cooking.
- Sauce Consistency: If the sauce looks too thin after cooking, let the pasta sit on ‘Keep Warm’ with the lid off for a few minutes to thicken. If too thick, add a splash of broth or cream.
- Substitutions: Use ground turkey, chicken, or plant-based crumbles in place of sausage. For a vegetarian version, skip the meat and add diced bell peppers or mushrooms during the sauté step.
- Preventing Burn Notice: Always deglaze the pot after sautéing meat by scraping off any browned bits before pressure cooking. Avoid stirring the pasta into the sauce—just press it down so it’s mostly submerged.
Serving Suggestions
- Top each bowl with extra Parmesan and a sprinkle of fresh basil for brightness.
- Serve alongside a crisp green salad with a tangy vinaigrette to balance the richness.
- A slice of garlic bread or warm focaccia makes an excellent accompaniment.
- Pair with roasted vegetables such as broccoli, zucchini, or asparagus for added nutrition.
Variations
- Chicken Alfredo Pasta: Replace sausage with diced chicken breast, omit marinara, and use 2 cups of chicken broth plus 1 cup heavy cream. Add 2/3 cup grated Parmesan and a pinch of nutmeg at the end for a creamy Alfredo-style pasta.
- Vegetarian Primavera: Skip the meat, and sauté a mix of zucchini, bell pepper, carrots, and mushrooms with the onion. Use vegetable broth instead of chicken broth. Stir in baby spinach with the cream at the end until wilted.
- Cheesy Taco Pasta: Use ground beef or turkey, add 1 tablespoon taco seasoning, replace marinara with a can of diced tomatoes and tomato sauce, and stir in 1 cup of shredded cheddar at the end.
- Seafood Pasta: Stir in peeled shrimp or chunks of firm white fish after pressure cooking—then cover and let the residual heat cook the seafood through in about 5 minutes.
Storage and Reheating
Store leftover pasta in an airtight container in the refrigerator for up to 4 days. To reheat, add a splash of broth or milk to loosen the sauce and microwave in 1-minute intervals, stirring between each, until hot. You can also reheat gently on the stovetop over medium-low heat, stirring and adding liquid as needed to restore creaminess. For best quality, avoid freezing cream-based sauces, as they may separate when thawed.
Frequently Asked Questions
- Can I use gluten-free pasta in the Instant Pot?
- Yes, but gluten-free pastas can become mushy more quickly. Reduce the pressure cook time by 1-2 minutes compared to wheat pasta, and check for doneness right after releasing the pressure. Some gluten-free pastas hold up better than others, so you may need to experiment with your preferred brand.
- How do I prevent pasta from sticking together?
- To minimize sticking, fan out the pasta evenly on top of the sauce and avoid stirring before pressure cooking. After cooking, stir immediately to separate any clumps. Adding a bit of oil to the liquid can also help.
- Can I double this recipe?
- You can double most Instant Pot pasta recipes as long as you do not exceed the maximum fill line. Cooking time remains the same, but it will take longer for the pot to come to pressure and release. Stir well before serving to ensure even saucing.
- Why did I get a burn warning?
- The burn warning usually means there are browned bits stuck to the bottom of the pot or not enough liquid. Always deglaze after sautéing, use enough broth or sauce, and avoid stirring the pasta in before cooking. If a burn notice appears, release pressure, stir in a bit more liquid, and resume cooking.
- Can I use jarred Alfredo or pesto sauce instead of marinara?
- Yes, you can substitute most jarred sauces. For Alfredo, reduce the added cream. For pesto, add after pressure cooking to preserve its fresh flavor. Adjust liquid if needed to maintain enough sauce for the pasta to cook properly.
- How do I adjust for different pasta shapes?
- As a general rule, halve the stovetop cooking time (rounded down) for most pasta shapes and use that as your Instant Pot pressure cook time. Short, sturdy shapes work best. For very small or delicate pastas, reduce the time by another minute to avoid overcooking.
