This sauce is so simple to prepare. I know you’ll enjoy how easy it is to make. First, heat up some oil and cook your onions until they are softened. I like to dice my onions fairly small so I don’t have a bunch of onion chunks in there, but feel free to make them a bit larger if that’s what you prefer.
After the onions are softened to your liking, add some garlic in and let it cook for another minute or so. You want to start to smell the garlic, but keep an eye on it, because you don’t want it to burn!
Finally, you add the remaining ingredients (seasonings, tomato sauce) and let it simmer so that the flavors really blend in together. I feel good about this cooking for 30-45 minutes, but if you have more time, let it simmer longer. The longer it simmers, the more flavorful it will be. Just be sure to stir occasionally so that it doesn’t get stuck to the bottom of the pan!

Use this sauce in these stuffed shells or toss these roasted veggies in it. Enjoy!

Ingredients
- 1 1.2 Tablespoon oil

In a medium sauce pot, heat the oil until warm. Once warm, add the diced onion and cook for 5-7 minutes, stirring occasionally. Once the onions are softened, add the garlic and cook for 1-2 minutes more, or until fragrant. Add the Italian seasoning, salt and pepper, and tomato sauce and stir to combine. Taste and adjust seasonings as desired. Place a lid on the pot and let simmer for 40-60 minutes. The longer the sauce is cooked, the better it will taste!
