Ingredients
  

Crockpot Spaghetti Ingredients
  • 1 lb Lean Ground Beef 450g
  • 1 tbsp Olive Oil 15ml
  • 1 medium Yellow Onion Diced
  • 4 cloves Garlic Minced
  • 1 can Crushed Tomatoes 28 oz (800g)
  • 2 tbsp Tomato Paste 30g
  • 2 cups Beef Broth 475ml
  • 1 tsp Kosher Salt 5g
  • 0.5 tsp Black Pepper 1g
  • 1 tsp Dried Oregano 2g
  • 1 tsp Dried Basil 2g
  • 1 lb Dry Spaghetti Noodles 450g
  • 0.5 cup Grated Parmesan Cheese 50g
  • 0.25 cup Fresh Parsley 15g, finely chopped

Equipment

  • 1 6-Quart Ceramic Slow Cooker Essential for slowly simmering the rich meat sauce.
  • 1 Large Skillet Needed to deeply brown the ground beef beforehand.

Method
 

Making the Crockpot Spaghetti
  1. Heat the olive oil in a large skillet over medium-high heat. Add the diced yellow onion and sauté for 3-4 minutes. Add the lean ground beef, breaking it into visible chunks. Cook until a deep brown crust forms (5-7 minutes). Stir in the minced garlic for the last minute. Drain any excess grease.
  2. Transfer the browned meat mixture into the slow cooker. Pour in the crushed tomatoes, tomato paste, and beef broth. Add the salt, pepper, dried oregano, and dried basil. Stir well until the liquid is a rich, dark red.
  3. Cover the crockpot and cook on LOW for 4 to 6 hours to allow the meat sauce to thicken and the flavors to develop.
  4. About 40 minutes before serving, break the dry spaghetti noodles in half and scatter them into the bubbling sauce. Press them down firmly until completely submerged.
  5. Turn the slow cooker to HIGH, cover, and let the pasta cook for 35-40 minutes until the noodles are thoroughly coated and perfectly al dente.
  6. Give the spaghetti a gentle toss. Leave it in the white ceramic crockpot for a rustic presentation. Generously sprinkle the entire top surface with grated parmesan cheese and finely chopped bright green fresh parsley before serving.

Notes

Do Not Overcook the Pasta: Check the noodles at the 30-minute mark to prevent them from becoming mushy.
Crust is Crucial: Deeply browning the ground beef beforehand locks in essential savory flavors that a crockpot alone cannot produce.
