Instructions
Press the sauté button on your Instant pot, then press the sauté button again to set sauté to "less" (some models might have the "adjust" button for this). Once it displays hot, add olive oil. Then add the chopped onion and garlic cloves.
Stir well, then add in 1/2 teaspoon salt. Cook the onions and garlic for 4 to 5 minutes until softened. Once done, add in the Italian seasoning and give a mix.
Then add 1 cup (8oz/240 ml) water and stir. Scrape the bottom of the pot with a wooden spatula to deglaze the pot and remove any browned bits that might have stuck to the bottom of the pot from sautéing the onions (although this is unlikely since we sauté on "less").
Next, add the tomato paste, balsamic vinegar and sugar. Then add in 14 oz of crushed tomatoes. This is around 1 & 1/2 cups of crushed tomatoes. Give a stir.
Add in the rigatoni pasta and then using your spatula, press the pasta slightly so that it's under the liquid a little.
Close the pot with the lid and press the pressure cook/manual button and cook on high pressure for 8 minutes with the pressure valve in the sealing position. Let the pressure release naturally for 2 minutes and then do a quick pressure release.
Press the sauté button again (it will be on "less" since that's how it was before), add in the cream. Then add in the mascarpone cheese. Stir until everything is well combined and the cheese melts. Also add 3/4 teaspoon crushed red chili flakes. You can add more to taste.
Add in handful of chopped spinach. Stir and cook for 1 minute, unplug the pot. Taste test and add more salt at this point if needed. Serve the pasta with freshly cracked black pepper, fresh basil. You can also top with some parmesan cheese!
Stove-top Instructions
Boil the pasta according to the instructions on the package and set aside. Heat a large pan on medium heat. Once hot, add olive oil and then add garlic, onion along with 1/2 teaspoon salt. Cook for around 4 to 5 minutes until the onions soften. Then add the Italian seasoning, tomato paste, balsamic vinegar and sugar. Give a quick stir. Add in the crushed tomatoes and let it heat up for 1 minute. Then add in the cream and mascarpone cheese mix until cheese melts and everything is nice and smooth. Add in the boiled pasta, mix until it's well coated with the sauce. Add the spinach and cook for 1 minutes. Add in the crushed pepper flakes. Stir and remove pan from heat. Serve with fresh black pepper, basil and parmesan cheese!
Notes
If using whole wheat rigatoni, I would probably increase the pressure cooking time to 10 minutes. This recipe has been tested with regular white flour rigatoni only.
If you are not a fan of spinach you can skip it. You can stir in some freshly chopped basil as well.
Veggies like peppers and mushrooms can be added to this paste. I would add the mushrooms (slice them thick) before pressure cooking whereas sliced peppers after the pressure cooking is done. They will retain their crunch and texture this way.
This recipe was tested in a 6qt. If you have a bigger 8qt, you may need to add some extra water (especially if you have a newer model prone to the burn message).
