Why I Make Homemade Spaghetti Sauce

  • Versatility: This sauce is incredibly versatile. It can be used in a variety of dishes, not just spaghetti. I use it for lasagna, as a base for a casserole, or even as a hearty dip. The options are endless!
  • Healthier: Homemade sauce is far healthier than store-bought versions. It’s free from preservatives, and you control the salt and sugar levels.
  • Convenience: The sauce is surprisingly simple to make. Plus, it’s designed for slow cooking, freeing up your day and reducing last-minute dinner stress. You can also make it in large batches and freeze it for later use.
  • Customizable: My recipe is easily adaptable to your personal preferences. You can adjust the flavors as you like, add more vegetables for a chunkier version, or remove the meat for a vegetarian sauce.

How To Make Crock Pot Spaghetti Sauce

  1. Begin by browning the beef, onions, and garlic in a large skillet, and make sure to drain off any excess fat.
  2. Combine the tomatoes, tomato paste, mushrooms, bay leaf, Italian seasoning, salt, and black pepper in a 4-quart crockpot, then stir in the browned meat mixture.
  3. Cover and let the magic happen – cook on LOW for 8 to 10 hours or on HIGH for 4 to 5 hours.
  4. Towards the end, add the sweet chopped pepper, discard the bay leaf, and prepare to serve.
  5. Ladle the sauce over your cooked spaghetti and garnish with a sprinkle of Parmesan cheese for the perfect finish. Delizioso!
  6. To Make It On The Stovetop: Follow the same initial steps to brown the meat and aromatics, and then add all ingredients into a large pot instead of a crock pot. Allow the sauce to simmer on the stovetop for at least 1.5-2 hours and up to 4 hours, stirring occasionally.

What Is The Difference Between Spaghetti Sauce, Marinara Sauce, & Pizza Sauce?

While all three sauces have tomatoes as their common base, their preparation, consistency, and usage make each unique.

  • Spaghetti Sauce: This refers to a rich, thick tomato sauce with various ingredients such as onions, garlic, mushrooms, ground beef, and herbs and spices. Spaghetti sauce is typically slow-cooked, allowing flavors to meld together. It is most commonly served over spaghetti but can be used in a range of pasta dishes.
  • Marinara Sauce: Originating from Naples, Italy, marinara is a quickly-cooked sauce primarily consisting of tomatoes, garlic, onions, and herbs. It does not contain meat, which distinguishes it from many spaghetti sauces. The name “marinara” derives from its origins as a sauce made by mariners due to its quick preparation time and the use of available ingredients.
  • Pizza Sauce: Pizza sauce is typically a simple, uncooked tomato sauce, often seasoned with herbs like oregano and basil. The sauce cooks directly on the pizza, producing a fresh and slightly tangy flavor. It’s usually thicker than marinara to stand up to the pizza toppings and less complex in flavor than a spaghetti sauce, as it’s meant to complement the flavors of the toppings rather than be the star of the dish.

Tips For Preparation

  • Slow and Steady: Let the sauce simmer for the full recommended cooking time. The long, slow cooking process helps develop deep flavors and tenderize the ground meat.
  • Tomatoes: Use quality canned tomatoes for the best flavor, since tomatoes are the backbone of the sauce.
  • Taste and Adjust: Remember to taste your sauce and adjust the seasonings as needed. You might want to add a pinch more salt, a bit more garlic, or a sprinkle of sugar to balance the acidity of the tomatoes.
  • Ground Meat: While this recipe uses ground beef, you can substitute it with ground turkey, chicken, pork, or even a meatless substitute like lentils for a vegetarian version. Or omit the ground meat.
  • Mushrooms: If you’re not a fan of mushrooms, feel free to leave them out.
  • Herbs: Experiment with the herbs. You can add a dash of red pepper flakes for heat or herbs like rosemary or thyme for a different flavor profile.

Storing Instructions

  • Storage: Once the sauce has cooled, store it in an airtight container in the refrigerator. It should last for up to a week.
  • Freezing: Place the cooled sauce in airtight containers or heavy-duty freezer bags. When you’re ready to use the sauce, thaw it in the refrigerator overnight and then heat it on the stove or in the microwave.
