2 cloves garlic, minced – Adds aromatic intensity.
2 teaspoons Italian seasoning – Enhances classic Italian flavor notes.
Pinch of red pepper flakes – Adds subtle heat and balance.

Pasta & Sauce

16 oz ziti pasta – Short, tubular pasta that holds sauce well.
3 cups water – Necessary for pressure cooking the pasta evenly.
32 oz marinara sauce – Forms the primary sauce base.
15 oz canned diced tomatoes, undrained – Adds texture, moisture, and acidity.

Cheese Layers

15 oz whole milk ricotta cheese – Creates creamy layers and balances the sauce.
3 cups shredded mozzarella cheese – Melts smoothly for a gooey, golden topping.
Salt and black pepper, to taste – Fine-tunes overall seasoning.
Dried parsley flakes (optional) – Adds visual contrast and mild herbal flavor.

Step-by-Step Instructions

Sauté the Aromatics – Set the Instant Pot to SAUTÉ, add olive oil and onion, and cook for 3–4 minutes until softened.
Brown the Sausage – Add Italian sausage and cook until no longer pink, breaking it into small pieces.
Add Seasonings – Stir in garlic, Italian seasoning, and red pepper flakes, cooking for 1 minute until fragrant.
Deglaze the Pot – Turn off the Instant Pot and add a splash of water if needed, scraping up browned bits to prevent burning.
Layer the Pasta – Add uncooked ziti over the sausage, then pour water evenly over the pasta.
Add Sauce Without Stirring – Pour marinara and diced tomatoes on top; do not stir to avoid triggering a burn notice.
Pressure Cook – Seal the lid, set to PRESSURE COOK for 4 minutes, then perform a quick release once done.
Incorporate Cheese – Stir the pasta, then mix in half the ricotta and 1 cup of mozzarella until combined.
Assemble for Baking – Transfer half the mixture to a greased casserole dish, top with remaining ricotta, and gently blend.
Bake Until Golden – Top with remaining mozzarella and parsley, then bake at 350°F for 20–25 minutes until bubbly and lightly browned.
Rest Before Serving – Let stand for 10 minutes to allow layers to set before slicing.

Recipe Notes & Tips

No-Stir Rule – Keeping sauce on top prevents pasta from sticking or burning during pressure cooking.

Resting Time Improves Structure – Helps the ziti hold together when serving.
Skip the Oven if Needed – Simply add all cheese after pressure cooking for a stovetop-style version.
Pot Size Friendly – Works equally well in 6-quart or 8-quart Instant Pots.
