What Ingredients are in Crock Pot Spaghetti Sauce?

This sauce is rich and delicious with deep, earthy flavor notes from the red wine and can be used on a variety of things like spaghetti and meatballs, Zoodles, pizza, or even to jazz up a bag of frozen ravioli. 

  • Extra virgin olive oil – I use Extra-virgin olive oil because it is an unrefined oil and is the highest-quality olive oil you can buy.
  • Onion – I use sweet white onions, like Vidalia but you can use a Spanish white or yellow onion.
  • Fresh Garlic – I prefer to mince fresh garlic because I feel there is a significant flavor and aromatics loss with jarred garlic.
  • Italian seasoning [paid link] – this is a blend of spices consisting of dried oregano, dried marjoram, dried thyme, dried basil, dried rosemary and dried sage.
  • Red pepper flakes – Increase or decrease these dried pepper flakes to adjust the spice level of your sauce.
  • Red wine – I use sweet red wine but dry red wine is also great in this sauce.
  • Crushed Tomatoes – Since tomatoes are the main ingredient, you want it to shine. Use the best brand you can afford on your budget. I use organic San Marzano Tomatoes [paid link].
  • Diced Tomatoes – Again, use the best brand you can afford on your budget.
  • Salt – I use fine Kosher salt but regular table salt may also be used. Add salt to taste depending on which tomatoes you buy may have salt added.
  • Black pepper – freshly cracked is most flavorful but ground black pepper also works well.

Can I omit the Red Wine?

If you prefer, you may omit the red wine and add some water or cooking stock (beef, chicken, or vegetable) in its place. It’s worth noting that the sauce will not carry the same rich earthy tones achieved from the wine.

  1. Do you cook the sauce separately before Cooking the raw meatballs in it? Or can everything be made at the same time? Hoping to use this recipe for Christmas Eve!

  2. So easy to prepare! I didn’t even bother with the stove top and instead just dumped it all into the crock and let it simmer. It was still excellent.
