Slow Cooker Marinara Sauce

Recipe by Star Anastasia at The Skinnyish Dish.

Prep time5 min
Cook time8–10 hr
TotalAbout 8 hr 5 min
MakesAbout 10 cups

Ingredients

  • 3 cans (28 oz) crushed tomatoes, preferably a higher quality brand such as Cento (diced, whole, or tomato sauce also work; drain extra liquid if using diced/whole)
  • 2 cans (14.5 oz) fire roasted diced tomatoes, drained
  • 8 garlic cloves, minced
  • 1 large yellow onion, diced
  • 2 tbsp dried oregano
  • 2 tbsp dried basil
  • 1/4 tsp red pepper flakes, more or less to taste
  • 1½ tsp kosher salt
  • 1 tsp pepper
  • 1–2 bay leaves (optional)

Steps

  1. Add everything to a 6-quart slow cooker and stir.
  2. Cook on low for 8 to 10 hours.
  3. Pull out the bay leaves, then taste and add more salt and pepper if needed.

Notes

  • Smoother: blend with an immersion blender (or let it cool and blend in batches).
  • Thicker: crack the lid and cook on high for 30 to 60 minutes.
  • Freezing: cool completely, portion about 2 cups per freezer bag, squeeze out the air, and freeze flat.
  • Reheating: if it looks watery after thawing, simmer uncovered on medium-low until thick.
  • Bitter? Some canned tomatoes can be. A couple teaspoons of sugar or sweetener fixes it.
