How long do I cook marinara sauce in the slow cooker?

Homemade marinara is one of those recipes in which the longer your cook it, the better it is.

You’ll cook this marinara recipe in the slow cooker on low for 9-11 hours or on high for 5-7 hours.

Can I make marinara sauce in the Instant Pot?

You bet! Here is how to make homemade marinara in the Instant Pot.

Depending on the size of your Instant Pot, you’ll likely need to cut this recipe in half. (An 8 quart Instant Pot might work for this amount of sauce, but since we haven’t test it, we can’t say for sure.) Bottom line: You always need to leave the top 1/3 of the Instant Pot empty to create room for pressure to build.

Set the Instant Pot to “Saute.” Pour the oil into the pot and heat until shimmery. Add the onion and cook, stirring, until softened, 4 to 5 minutes. Stir in the garlic and cook for 30 to 60 seconds more, until fragrant.

Press “Cancel.” Stir in the rest of the ingredients. Lock and seal the lid. Cook at high pressure for 10 minutes, then quick release the pressure. Taste and season with salt and black pepper.
