This Instant Pot baked ziti was born out of desperation one crazy Sunday when I wanted a proper family dinner but only had an hour and a hungry crowd. I had been nervous to use my new pressure cooker, but after a few experiments I finally cracked the code and now this shortcut ziti is in constant rotation. You get the rich flavor and golden cheese of the “real” thing without spending half your weekend on prep and clean up.
One Sunday my sister tried this recipe for her daughter’s soccer team party and every last bit disappeared. The girls scraped the pan clean and my sister got dubbed the team’s official pasta chef. It is honestly a delight to see people light up over a simple homemade dish.
Ingredients
- Italian sausage: for deep savory flavor and moisture balances everything
- Ziti or penne pasta: holds sauce perfectly choose sturdy brands for best texture
- Good quality marinara sauce: is key since it builds the flavor base
- Whole milk ricotta: for that ultra creamy classic bite avoid part skim which can turn grainy
- Mozzarella cheese: grated from a block ensures the best melting
- Diced tomatoes: for extra texture and bright pops of flavor use canned with no extra salt
- Fresh garlic: for that signature aroma and punch hate to say it but garlic powder just cannot compare
- Yellow onion: adds sweetness and depth choose firm ones with no soft spots
- Olive oil: helps soften the onion and carries all the flavors
- Water: ensures the pasta cooks through don’t skimp since the Instant Pot needs enough liquid
Step-by-Step Instructions
- Building the flavor base:
- Turn your Instant Pot to sauté mode and wait for it to read Hot. Add olive oil and finely chopped onion then cook stirring often until the onion is soft and translucent. Add crumbled Italian sausage and keep breaking it up as you cook until no pink remains.
- Adding aromatics:
- Add minced garlic and cook for about one minute just until you smell that delicious aroma. Do not let it brown because burnt garlic turns the whole dish bitter. If anything sticks use a splash of water and scrape the bottom clean.
- Layering for pressure cooking:
- Add uncooked ziti pasta right over the sausage in a single layer. Pour water evenly over the pasta. Spoon marinara sauce and diced tomatoes over the top but do not stir. This keeps the pasta from burning to the Instant Pot base.
- Pressure cooking magic:
- Seal the lid and set the valve to sealing. Cook on high pressure for four minutes. When the time is up do a quick release by moving the valve to venting being careful to let out steam gradually if there is lots of liquid.
- Stirring and cheese adding:
- Open the lid carefully and stir the mixture well to combine everything. While it is still hot add half the ricotta and one cup of grated mozzarella then stir until just melted.
- Transferring for baking:
- Preheat your oven to three hundred fifty degrees. Spoon half the ziti mixture into a greased casserole dish then dot the rest of the ricotta over that layer. Top with remaining ziti mixture.
- Final baking step:
- Scatter the rest of the mozzarella over the top and sprinkle with a bit of dried parsley if you like. Bake for about twenty to twenty five minutes until bubbling and the cheese is golden brown.

Ricotta cheese is my favorite part hands down. That creamy tang is what sets baked ziti apart from all other pasta bakes. My kids have even started fighting over the corner pieces with the most ricotta and crispy cheese. We always laugh about who called dibs first because everyone wants the extra cheesy scoop.
Storage Tips
Instant Pot baked ziti keeps in the fridge in an airtight container for up to four days. I like to portion out servings for weekday lunches since the flavor gets even better overnight. For longer storage freeze individual slices wrapped in plastic then stored in a freezer bag. Thaw overnight in the fridge or reheat from frozen covered with foil at three hundred fifty degrees until hot.
Ingredient Substitutions
You can swap Italian sausage with mild or spicy versions depending on your taste or use ground beef turkey or even a split. Vegetarian sausage or plant based crumbles work too but may need a boost of extra Italian herbs. If grated mozzarella is not available provolone or fontina can add great richness.
Serving Suggestions
Give this baked ziti a few minutes to rest after baking to set. Serve hot with a crisp green salad and garlic bread for a complete meal. For a special touch sprinkle fresh basil or parsley over the finished dish right before taking it to the table.

There is something about seeing a bubbling casserole fresh from the oven that gathers everyone to the kitchen with big smiles.
Common Recipe Questions
- → Why is layering important in this dish?
Layering ingredients prevents sticking and burning at the bottom of the pot, ensuring even pasta cooking and a smooth finish.
- → Can different meats be used?
Absolutely! Italian sausage provides flavor, but ground beef, turkey, or even a veggie mix make good substitutes.
- → Is the oven step necessary?
Baking creates the classic golden cheese top, but you can skip this if you prefer and add all cheese after pressure cooking.
- → Does this work in a 6-quart Instant Pot?
Yes, the same quantities fit both 6- and 8-quart Instant Pots without adjustments.
- → Any tips for perfect pasta texture?
Don’t stir before pressure cooking and let the dish rest ten minutes after baking—this keeps the pasta from getting mushy.
- → How should leftovers be stored?
Store covered in the fridge for up to four days or freeze portions for easy meals later. Reheat thoroughly before serving.
