Start by heating a skillet over medium heat. Drizzle in the olive oil, allowing it to warm up before adding the ground meat, onion, garlic powder, and kosher salt. Cook for about 5 to 7 minutes, stirring occasionally, until the meat is cooked through and the onion is tender.
Once the meat is ready, drain any excess fat from the skillet. This step is crucial to prevent a greasy sauce.
Now, pour one jar of pasta sauce into the bottom of your slow cooker. This will create a flavorful base for the noodles.
Next, add 1 cup of water into the slow cooker and stir it into the sauce, ensuring that everything is well combined.
It’s time to break the spaghetti noodles in half. Place them gently on top of the sauce mixture in the slow cooker. This ensures they cook evenly and absorb all the flavors.
Layer the cooked meat mixture on top of the spaghetti noodles. Sprinkle grated parmesan cheese over the meat, adding a creamy texture that will melt into the dish.
Now, cover everything with the second jar of pasta sauce. Make sure it’s evenly distributed to keep the noodles moist while they cook.
Secure the lid on your slow cooker and set it to cook on high for 2 to 2 and a half hours or low for 6 hours. The slow cooking process allows the flavors to meld beautifully, creating a rich and delicious meal.
When the cooking time is up, carefully remove the lid. Stir everything together, making sure to combine all the ingredients for a consistent flavor throughout.
