Ingredients and Variations

Beef: Ground chicken and turkey can be mixed with ground beef, but for a little more zest, add some ground Italian sausage. Use this hand meat chopper while cooking to break it up easily.

Tomatoes: Whole canned tomatoes add visual interest and texture, but two cans of diced tomatoes can be used instead.

Mushrooms: Canned or fresh mushrooms can be used interchangeably, and some shredded zucchini, carrots, and bell peppers can be added in for those picky eaters that don’t normally care for veggies!

Seasonings: Short on time? Whip up this quick DIY Italian seasoning blend and use it in everything from dips to dressings as well as spaghetti sauce.

How to Cook Spaghetti Sauce in a Slow Cooker

If your slow cooker has a saute function, no need to use the skillet!

  • Cook ground beef and add it to a slow cooker with the remaining ingredients (as per the recipe below).
  • Cover and cook on high for 4 hours or on slow for 8 hours (or longer). Garnish as desired, and serve.

Tips & Tricks

There are many ways to thicken, or thin out, spaghetti sauce.

  • Add some reserved pasta water to the spaghetti sauce to thicken it.
  • Make a slurry by mixing equal amounts of cornstarch and cold water together before adding them to the pot and letting the sauce cook down with the lid off.
  • Thin out a sauce that’s too thick by adding some water or broth. Adding more canned tomatoes will only make the sauce more acidic.
  • Feel free to double up the recipe and freeze portions for future meals!

How To Cook The Perfect Pasta

  • Add a tablespoon of salt to boiling water and add noodles. Stir immediately to keep the noodles from sticking together.
  • Cook spaghetti to “al dente” which is cooked but still firm.
  • Do not rinse the pasta because the starch that’s been released helps the sauce cling to it.
  • Reserve pasta water to thicken the sauce later, if needed.

  • Freeze for up to 3 months in zippered bags and thaw in the refrigerator overnight or back in the slow cooker on low.
