How to Make Slow Cooker 3-Ingredient Pasta
Step 1: Add the Ingredients
Lightly grease the inside of a 4- to 6-quart slow cooker.
Add the uncooked penne pasta and pasta sauce.
Stir well to make sure the pasta is evenly coated.
Step 2: Add the Cheese
Sprinkle about half of the mozzarella cheese over the pasta mixture and stir gently.
Reserve the remaining cheese for the final stage of cooking.
Step 3: Slow Cook
Cover and cook on LOW for approximately 2 to 3 hours.
Stir once or twice during cooking if needed to keep the pasta evenly coated.
The pasta should be tender but not mushy.
Slow cooker temperatures vary, so begin checking the pasta toward the two-hour mark.
Step 4: Add the Remaining Cheese
Once the pasta is tender, sprinkle the remaining mozzarella over the top.
Cover again and cook for about 10 to 15 minutes, or until the cheese is completely melted.
Step 5: Serve
Turn off the slow cooker and allow the pasta to rest for a few minutes.
Spoon into bowls and serve warm.
Tips for the Best Slow Cooker Pasta
Choose a sturdy short pasta such as penne, rigatoni, or rotini. These shapes tend to hold up better during slow cooking.
Make sure the pasta is well coated with sauce so it cooks evenly.
Avoid cooking the pasta longer than necessary because it can become soft or mushy.
Because different slow cookers heat differently, check the pasta regularly toward the end of cooking.
What to Serve With Slow Cooker Pasta
This simple pasta makes a satisfying meal on its own, but it also pairs well with easy sides.
Serve it with:
- Green salad
- Garlic bread
- Steamed broccoli
- Roasted vegetables
- Green beans
- Crusty bread
A fresh salad is especially good with the rich, cheesy pasta.
Make-Ahead Instructions
This recipe is best served shortly after cooking because pasta continues to soften as it sits.
If preparing it for a gathering, plan to finish the pasta close to serving time and use the WARM setting only briefly to keep it hot.
Storage
Transfer leftovers to an airtight container and refrigerate for up to 3 days.
Reheat gently in the microwave or in a saucepan over low heat. Add a small splash of water or sauce if the pasta has become dry.
Easy Variations
Although the basic recipe uses only three ingredients, it can easily be customized.
Add cooked ground beef or Italian sausage for a heartier meal.
Stir in chopped spinach, mushrooms, bell peppers, or zucchini for extra vegetables.
For a stronger cheese flavor, replace some of the mozzarella with Parmesan, cheddar, or Italian cheese blend.
A pinch of Italian seasoning or red pepper flakes can also add extra flavor, although these additions will take the recipe beyond three ingredients.
Frequently Asked Questions
Can I use another type of pasta?
Yes. Penne, rotini, rigatoni, and other sturdy short pasta shapes work well.
Do I need to boil the pasta first?
No. The pasta goes into the slow cooker uncooked.
Can I use homemade pasta sauce?
Absolutely. Homemade tomato sauce can be used in place of jarred pasta sauce.
Can I use a different cheese?
Yes. Mozzarella melts beautifully, but cheddar, Monterey Jack, provolone, or an Italian cheese blend can also work.
