Slow Cooker Marinara Sauce; With this simmering on the slow cooker all day, you won’t be able to resist testing it with a slice of bread over and over again.  It’ll make Nana proud.

It all comes down to this – the final Slow Cooker Monday. Spring is here and, even though I use my slow cooker all year round, it will be time for a new ‘theme’ for Monday posts here in the PtS kitchen. Sadly, I have no idea what that theme is yet. It will be a shocker to us both 😉

In the mean time we should recap the slow cooker recipes of the last 13 weeks. If I could find a way to make this into a cheesy sitcom montage I would. Just play some corny music in your head and pretend there are hugs and tears involved. (Chipotle burrito filling, oh how I will miss you).

10 hours 5 minutes
Serves: 12


  • 3 tbs extra virgin olive oil
  • 2 onions - minced
  • 6 cloves of garlic - minced
  • 1 cup sliced mushrooms
  • 1/2 tsp anchovy paste
  • 2 tbs tomato paste
  • dash red pepper flakes
  • 2 tsp dried oregano
  • 1 cup dry red wine
  • 28 oz crushed tomatoes
  • 28 oz diced tomatoes - drained
  • 28 oz tomato sauce
  • 2 tbs soy sauce
  • 2 tbs brown sugar
  • 1/2 cup fresh basil - snipped


  • Heat skillet over medium high heat and add oil until shimmering. 
  • Stir in the onions, garlic, mushrooms, anchovy paste, tomato paste, pepper flakes, and oregano to the pan. 
  • Cook for 8 to 10 minutes, until the onion is beginning to brown. Stir in the wine and scrape up any browned bits. 
  • Cook about 5 minutes, until thickened.
  • Pour the tomatoes and soy sauce into a slow cooker; add the onion mixture. 
  • Cook on low for 9 to 11 hours.
  • Stir in the brown sugar and basil. 
  • Serve immediately or store in airtight containers.


*Because I don't like a chunky sauce and find I can sneak more veggies in if I don't see them, I took my immersion blender to the sauce at the very end just to smooth things out.  I froze my leftovers in ziplock bags

    Why oh why did i stumble upon this blog right before going to bed?! I’ll be dreaming of delicious food all night!

  4. This is going to be the year I make tomato sauce… I swear I will. This looks so good and comforting as we hit a cold and rainy (or in our case snowy) spring.

  5. I love how rich flavored this marinara sauce sounds Kita – with anchovies, soy sauce, red wine and mushrooms!

  6. I am determined to use my slow cooker all through the summer. Recipes like this will be perfect for an easy dinner!
