  The long, slow cooking process melds the flavors of the meat, tomatoes, and herbs perfectly. It tasted like it had been simmering on the stove all day, but without the babysitting .

• It’s a massive batch for meal prep.
  This recipe makes enough sauce for several meals. I portioned it out and froze it, which made for incredibly easy high-protein dinners on busy weeknights .

Common Mistakes to Avoid:

1. Not breaking up the whole tomatoes: If using whole peeled tomatoes, be sure to crush them with a spoon or your hands when adding them to the crockpot. They will break down further during cooking, but an initial crush helps them meld into the sauce from the start .

2. Forgetting to remove the bay leaves: If you add bay leaves for extra flavor, remember to remove them before serving. They are very tough and can be a choking hazard if left in the sauce .

3. Using a sauce with added sugar: For a strictly low-carb or keto diet, always check the labels on your canned tomatoes and tomato sauce to ensure no added sugar is present .

Required Equipment:

• Slow Cooker: The essential appliance for hands-off, slow-cooked perfection, allowing the flavors to develop all day .

• Immersion Blender: A simple tool for blending the sauce to your desired consistency, from chunky to completely smooth, right in the crockpot .

• Wooden Spoon: Ideal for stirring and gently breaking up tomatoes without scratching your slow cooker’s ceramic insert .

Storage Instructions:

Store leftover sauce in an airtight container in the refrigerator for up to 5 days . For longer storage, this sauce freezes beautifully for up to 3 months . Cool the sauce completely, then portion it into freezer-safe bags or containers. For easy thawing, freeze in flat 2-cup portions .
