The Slow-Cooker Meat Spaghetti Sauce Recipe

I made my own meat spaghetti sauce one day. It was the result of one of my "let's put in a little of this, a little of that" cooking days and it turned out really well! So I'm posting the recipe here so I won't forget it. :-)

• I put some frozen beef strips into the crock pot along with some frozen homemade chicken broth. Cooked on high until the broth melted.
• Once the broth was liquid, I added -- not all at the same time, but spread out during the day "as the Spirit moved me":
• a few beef bouillon cubes
• a can of tomato paste -- and a can-full of water to clean out the can
• some ketchup -- because I had an almost-empty bottle of it in my fridge. I used a bit of cider vinegar to wash out the bottle, then dumped that into the pot, too.
• A spoonful of Marmite -- I keep a jar of it on hand to add umami to dishes. Could also substitute other good umami sources, depending on what sub-tastes you like: Worcestershire sauce, soy sauce, ponzu sauce, dashi, or Vegemite (we can't use Vegemite because Bri is allergic to celery)
• some Italian seasoning
• dried onions
• garlic powder
• salt & pepper
• I let that cook on low for several hours. 
• Later, after the beef was good and tender, I put the beef and some liquid into my food processor and shredded it, then put it back into the pot.
• I made pasta and put about 1/2 cup of finished hot pasta water into the sauce, too
