How to Make Instant Pot Spaghetti
Let's start with the ingredients for pressure cooking spaghetti. Actually they are so simple that it is almost hard to believe just how fabulous this Instant Pot spaghetti sauce tastes.
- A Can of Whole Peeled Tomatoes - Canned tomatoes are the best choice for this recipe. Processed tomatoes are harvested when they are ripe red. These ripe tomatoes are processed almost immediately. The tomatoes are canned within about 6 hours from when they were harvested according to the California Tomato Growers Association. Store bought tomatoes are harvested when they are green and often have a tougher skin in order to survive shipping from the fields to the grocery store.
- Meat - We love ground beef, but you can use ground pork or turkey if you prefer. You can also omit the meat entirely.
- Basil - Fresh basil leaves are ideal, but you can also use dried basil. Depending upon how much basil you use, dried may be the easier and more budget-friendly choice.
- Garlic Cloves
- Butter and Oil - Butter adds and wonderful creamy depth of flavor to the sauce. Butter also helps to balance out the acidity of the tomatoes. I add a smaller amount of oil to help with browning the meat and garlic. Butter is what makes this the Best Tomato Sauce Recipe ever!
- Spaghetti Noodles - Only use dried noodles. Fresh spaghetti cooks too quickly to be used in the Instant Pot.
