Ingredients
- 18 oz spaghetti
- 1½ lbs ground beef
- 1½ tablespoons olive oil
- 3 tablespoons butter
- 1½ teaspoons Italian seasoning
- ¾ teaspoon salt
- ¾ teaspoon black pepper
- 6 cloves garlic, minced
- 1½ cups heavy cream
- 1½ cups shredded cheddar cheese
- ¾ cup grated Parmesan cheese
- 9 oz processed cheese cubes
- 6 oz cream cheese
- ¾ teaspoon garlic powder
- ¾ teaspoon onion powder
- ¾ cup reserved pasta water
Step-by-Step Instructions
- Cook the Pasta: Bring a large pot of salted water to a boil. Add the 18 ounces of spaghetti and cook until tender, according to package instructions (usually about 8-10 minutes). Reserve ¾ cup of the pasta water before draining. Set the drained pasta aside.
- Brown the Beef: Heat 1½ tablespoons of olive oil in a large skillet over medium heat. Add the 1½ pounds of ground beef and cook, breaking it apart with a spatula until browned and no pink remains, about 6-8 minutes. Drain any excess fat if necessary. Transfer the cooked beef to a slow cooker.
- Season the Beef: In the slow cooker with the beef, add ¾ teaspoon salt, ¾ teaspoon black pepper, 1½ teaspoons Italian seasoning, ¾ teaspoon garlic powder, and ¾ teaspoon onion powder. Stir everything together well to evenly distribute the spices.
- Add Garlic & Butter: Return the skillet to medium heat. Melt 3 tablespoons butter and add the minced garlic (6 cloves). Sauté for about 1 minute until fragrant and golden but not burnt. Pour this garlic butter mixture into the slow cooker, stirring to combine with the beef and seasonings.
- Create the Cream Base: Pour in 1½ cups heavy cream into the slow cooker. Stir gently so the cream mixes with the seasoned beef and garlic butter.
- Melt the Cheeses: Add 6 ounces cream cheese and 9 ounces processed cheese cubes to the slow cooker. Stir continuously until the cheeses melt completely and form a smooth, creamy base.
- Add Remaining Cheese: Stir in 1½ cups shredded cheddar cheese and ¾ cup grated Parmesan cheese. Continue to stir until the sauce thickens and turns rich and creamy.
- Combine with Pasta: Add the cooked spaghetti to the slow cooker. Toss the pasta thoroughly in the cheddar cream sauce, ensuring every strand is coated.
- Adjust Consistency: Slowly pour in the reserved ¾ cup pasta water a little at a time, mixing gently, until the sauce reaches your desired thickness and is silky smooth.
- Slow Cook: Cover the slow cooker and cook on low for 1 to 2 hours. This allows the flavors to deepen and the sauce to become luxuriously creamy and hot.
Pro Tips for Perfect Results
- Use fresh garlic: It gives a bright aroma and better flavor than powdered garlic.
- Reserve pasta water: The starchy water helps loosen the sauce while maintaining its creamy texture.
- Cook pasta al dente: Since it will cook further in the slow cooker, slightly undercooked pasta prevents mushiness.
- Stir occasionally: During slow cooking, stir every 30 minutes if possible to avoid cheese sticking or separating.
- Choose quality cheese: Sharp cheddar and freshly grated Parmesan elevate the depth of flavor.
Variations and Substitutions
- Meat alternatives: Swap ground beef with ground turkey or chicken for a leaner version.
- Healthier swaps: Use reduced-fat cream cheese and cheddar, and replace heavy cream with half-and-half or evaporated milk.
- Vegetarian option: Replace beef with sautéed mushrooms, lentils, or plant-based ground meat.
- Spice it up: Add crushed red pepper flakes or a dash of smoked paprika for heat and smoky undertones.
- Pasta alternatives: Use whole wheat spaghetti or gluten-free pasta if needed.
Storage and Reheating Tips
This dish stores wonderfully in the refrigerator for up to 3 days. Transfer leftovers to an airtight container and cool completely before refrigerating. To reheat, warm gently on the stovetop over low heat or in the microwave, adding a splash of milk or reserved pasta water to loosen the sauce and restore its creamy consistency. Avoid overheating to prevent the dairy from separating. You can also freeze portions for up to 1 month; thaw overnight in the refrigerator before reheating.
FAQs
- Can I make this recipe without a slow cooker?
- Yes! After preparing the sauce and combining ingredients, simmer gently on the stove over low heat for 20-30 minutes, stirring often to melt cheese fully and thicken the sauce.
