Spicy Vegetarian Slow Cooker Spaghetti Sauce

This is another delicious vegetarian slow cooker recipe that I can make in bulk and freeze – though I don’t think it’s going to last me as long as my bean and vegetable chili! This is spicy and just the right consistency; the suggestion for ridged noodles to help scoop up the sauce is a great one. I call my version ‘spicy’ vegetarian spaghetti sauce, but the slow cooker helps mellow out the taste considerably.

Prep Time: 35 minutes
Cook Time: 9 hours
Storage Time: 25 minutes
Total Time: 10 hours from cutting board to freezer shelf

Ingredients:

  • 2 Tbsp. olive oil
  • 1 onion, diced
  • 3 cloves garlic, minced
  • 2 carrots, chopped thinly
  • 1 (8-ounce) package sliced mushrooms
  • 1 green bell pepper, chopped
  • 1 roma tomato, diced
  • 1 jalapeno pepper, sliced
  • 8 oz. can of pitted black olives, roughly chopped
  • 3 (8 oz.) cans tomato sauce
  • 2 (14 oz.) cans diced tomatoes, undrained; I used preseasoned varieties – 1 “italian herbs” & 1 “basil & garlic”
  • 6 oz. can tomato paste
  • 1 tsp. dried Italian seasoning
  • 1/4 tsp. pepper
  • 1/2 tsp. salt
  • 2 tsp. sugar

Preparation:

  • Cook onions and garlic in oil in large nonstick pan¬†over medium heat. Stir and cook for 4-5 minutes until tender. If you’re allergic to onions (like I am), this is a good time to take out any if you think maybe it’s “too much.”
  • Add carrots, mushrooms, tomatoes, jalapeno, olives, and bell pepper. Stir for 2-3 minutes.
  • Place vegetables into bottom of 6-7 quart slow cooker.
  • Add remaining ingredients into the slow cooker. I took a few minutes to spread the sauces evenly over the vegetables; the added step of mixing everything together before layering them over seems¬†unnecessary, and I wouldn’t recommend it.

Cook:

  • Cover slow cooker and cook on low for 7-8 hours.
  • Uncover, stir thoroughly, then leave cover off and turn heat to high. Cook, uncovered, for 1 more hour to thicken sauce.

Storage:

  • At this point the sauce can be frozen. Divide into smaller portions and cool in refrigerator. Wrap, label, and freeze the sauce up to 3 months.
  • To thaw and reheat, thaw sauce overnight in refrigerator. Pour into skillet and heat over medium heat, stirring frequently, about 15-20 minutes or until sauce bubbles and is thoroughly heated.

I took the original of this recipe off about.com’s “Busy Cook” section, but I made several changes to the original recipe to make it more to my tastes. I added a jalapeno pepper, tons of olives, a fresh tomato, and a little bit more canned sauce to the recipe, calling for a slightly larger crock pot size.
