These Instant Pot stuffed shells are perfect if you enjoy pasta and one-pot dinners. You’ll never go back to regular stuffed shells after seeing how simple these are to prepare!
Making pasta in an Instant Pot is the simplest thing to do. It essentially transforms any pasta meal into a dump-and-go recipe. It saves a lot of time and the pasta turns out perfectly every time.
Though there is some effort needed to stuff the shells, after that it’s all smooth sailing as you allow the Instant Pot to do the rest of the work.
Ingredients You’ll Need
- Cheese – This recipe has three varieties of cheese: mozzarella, ricotta cheese, and parmesan cheese, which gives it a delicious flavor.
- Garlic – Always use fresh garlic that hasn’t been kept in the refrigerator for too long. This has the best flavor and no bitterness that comes from older garlic.
- Egg – Use large eggs at room temperature.
- Salt & Pepper – This is what really brings out the taste in this dish, so don’t skip the salt and pepper. You can also taste the food once it’s finished cooking and add additional to your liking.
- Jumbo Pasta Shells – These pasta shells have enough space for you to add the tasty filling.
- Marinara Sauce – Use your favorite Marinara Sauce or make your own.
- Water
- Parsley – Chopped for garnish.
How to Make Instant Pot Stuffed Shells
In a mixing bowl, combine the ricotta, half the mozzarella, the Parmesan, garlic, egg, half of the salt and pepper. Transfer the mixture to a pastry bag, or a gallon-sized plastic bag and snip the corner.
Boil the pasta shells until al dente, just about 8-10 minutes. You don’t want to overcook them, because they will continue to cook under pressure. Drain the water from the shells and run them under cold water to stop the cooking.
Fill each pasta shell with the filling, about a tablespoon per shell.
Spray the inside of the Instant Pot with cooking spray and place the trivet in the Instant Pot. Stack the filled shells on the trivet.
Pour the water down the side of the Instant Pot so it fills up underneath the shells. You don’t want to pour the water directly onto the shells or they will become waterlogged and soggy.
Pour the marinara sauce over the top of the shells. Sprinkle with remaining salt and pepper. Do not stir it though. You need it to remain in this order while it cooks.
Close the lid and turn the valve to sealing, if necessary. Press the Pressure Cook or manual button and set to cook for 10 minutes on high pressure. When it’s done, do a quick pressure release.
Top the shells with the remaining mozzarella cheese. Set the lid back on the pot for about 3 minutes, until the cheese has melted. Serve with a sprinkle of parsley and/or Parmesan cheese, as desired.
Helpful Tips and Advice
- Since we are layering the shells, the amount of pasta shells to use can vary depending on the size of your Instant Pot. If you have a 6-quart Instant Pot – use 16 stuffed shells. If you have an 8-quart Instant Pot – use 20 stuffed shells.
- Fill the pasta shells with ricotta filling using a piping bag (or a ziplock bag with one corner cut). It saves time over spooning the filling into each shell.
- When stacking the filled shells on the trivet it doesn’t matter if the pasta is touching the sides of the pot. They won’t burn.
