Instant Pot Ziti
One pot, no boiling, no oven
A pressure-cooker ziti that cooks the pasta right in the sauce — sausage, marinara, and dry ziti go in together, then ricotta and mozzarella melt in at the end for a weeknight one-pot meal.
This version skips the boiling pot and the oven entirely: the ziti pressure-cooks in seasoned sauce, absorbing flavor as it softens. Because the pasta and liquid are measured together, the ratio matters more than in an oven bake — follow it closely and the pasta comes out evenly cooked.

Equipment
- 6-quart electric pressure cooker
- Wooden spoon
Directions
- 1
On the sauté setting, brown the sausage with the onion and garlic, breaking up the meat.
⏲ Sauté sausage: ~8 min
Look for: Sausage cooked through with no pink.
Food safety: Cook sausage to 160°F (71°C) during the sauté step.
- 2
Turn off sauté. Scatter the dry ziti over the meat in an even layer — do not stir.
- 3
Pour the marinara and then the water over the pasta so it is just submerged; press the pasta down but leave it unstirred to avoid the scorch warning.
Look for: Pasta should be mostly covered by liquid.
- 4
Seal and pressure-cook on high for 5 minutes, then quick-release carefully once the time is up.
⏲ Pressure cook: ~5 min
Look for: Pasta tender but not mushy; it firms slightly off heat.
- 5
Stir in the ricotta and Parmesan, then fold in the mozzarella until it melts into the hot ziti.
Food safety: Reheat leftovers to 165°F (74°C).
- 6
Let stand 5 minutes uncovered to thicken before serving.
⏲ Rest: ~5 min
Troubleshooting & common mistakes
- Stirring the pasta into the liquid, which triggers the burn warning.
- Skipping the quick release, which overcooks the pasta.
Make-ahead, storage & reheating
- Make ahead
- Best served fresh; the pasta keeps absorbing liquid, so make it close to serving.
- Storage
- Refrigerate up to 4 days; it thickens and may need a splash of water when reheating.
- Freezer
- Freezing is possible but the pressure-cooked pasta softens further on thawing.
- Reheating
- Reheat on the stovetop or microwave with a little water or broth to loosen.
Recipe notes
- Layering — sauce on top, pasta below — is what keeps starch off the hot base and prevents scorching.
FAQ
- Why not stir before cooking?
- Stirring lets starchy pasta settle onto the hot base and scorch; layering avoids the burn warning.
- Can I use ground beef?
- Yes — brown it in place of the sausage and add a little extra seasoning.
