Slow Cooker Classic Marinara Sauce

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).

  2. Stir in the onions, garlic, mushrooms, anchovy paste, tomato paste, pepper flakes, and oregano to the pan. 
  3. Cook for 8 to 10 minutes, until the onion is beginning to brown. Stir in the wine and scrape up any browned bits. 
  4. Cook about 5 minutes, until thickened.

*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
