There is a time and place for using ripe tomatoes to create a homemade pasta sauce. But when garden-fresh tomatoes aren’t in season, you can still create a fantastic marinara from scratch using canned tomatoes from the pantry.

This sauce is already simple enough, but if you want to make it super easy, use frozen veggies so that you don’t even have to chop a single thing. Related: How to Freeze Onions, How to Freeze Garlic, How to Freeze Carrots, and How to Freeze Peppers.

Canned tomatoes from the store work really well, but if you’re a home canner, you might be interested in learning How to Can Whole Tomatoes and Canning Stewed Tomatoes so that your pantry is always loaded with the right ingredients for this sauce.

If you are looking for tomato sauce using fresh tomatoes, check out our Crockpot Spaghetti Sauce. It’s made with gloriously ripe tomatoes, straight from the garden or farmer’s market. I have also used frozen/thawed tomatoes with great results. Related: How to Freeze Tomatoes.

Does Spaghetti Sauce Freeze Well?

Yes! You can store it in freezer-proof bags, plastic containers, souper cubes, or wide-mouth glass canning jars. It still tastes delicious when thawed, and you get the benefit of a homemade sauce ready to go for a fast weeknight meal.

Is it Ok to Freeze Spaghetti Sauce With Meat?

Yes! Just make sure the meat is cooked to temperature before adding it to the sauce and freezing. Allow the bolognese sauce to fully cool before pouring into freezer storage containers.

Pro Tips/Recipe Notes

  • Feel free to add any other veggies that you love. Grated zucchini (related: How to Freeze Zucchini), mushrooms, butternut squash, or frozen pumpkin all work great.
  • If you have picky eaters, saute the veggies until softened. Then add 1 can of diced tomatoes and blend using an immersion blender, traditional blender, or food processor. Then add the rest of the tomatoes/tomato sauce and cook according to the instructions in the recipe card below. All those extra veggies are now our secret. 
  • This recipe calls for a touch of brown sugar. If you’re out, did you know you can make Homemade Brown Sugar? It’s so easy!
  • This freezer pasta sauce gets better the longer you let it simmer. It’s a perfect candidate for the slow cooker if you don’t want it on your stove for 2+ hours.
  • The (optional) baking soda is a great way to neutralize the natural acidity of tomatoes without adding additional sugar.

Ingredients

Instructions

  • In a heavy saucepan, saute onions, garlic, and carrots in olive oil until softened (~10 minutes).
  • Add diced tomatoes, tomato sauce, basil, parsley, oregano, brown sugar, and bay leaves. Stir to combine.
  • Bring to a boil for 1 minute (stir to prevent popping). Reduce heat to a simmer.
  • Place a lid slightly ajar on the saucepan to allow steam to escape. Cook down for 1-2 hours until it has reached your desired consistency.
  • {optional} Add 1 tbsp of butter, and cook sauce for an additional 15 minutes.
  • {optional} Add 1/8 tsp baking soda, and stir well to combine. The baking soda will react with the tomatoes and cause a bit of foaming.
  • Salt & pepper to taste.
  • For best results: allow sauce to cool to room temp in the saucepan. Cover and refrigerate for up to 24 hours.
  • Transfer cooled sauce to freezer containers and freeze until solid.

Notes

Slow cooker Instructions: Combine all ingredients except for butter and baking soda in the slow cooker. Cook on low for 6 hours, or high for 4 hours. Add butter and baking soda and then cook for an additional 30 minutes.
