Slow Cooker 3-Ingredient Pasta

There are some dinners that feel almost too easy to be this creamy and satisfying, and this Slow Cooker 3-Ingredient Pasta is exactly that. It takes tender pasta, rich marinara, and soft cream cheese and turns them into a velvety, comforting dish that tastes like you spent hours at the stove. The slow cooker does all the work, and you are left with a warm, cozy meal that everyone at the table will love.

What I love most about this recipe is how effortlessly it comes together. You do not boil the pasta first, you do not make a separate sauce, and you do not need a long list of ingredients. Just three main ingredients, a little water or broth, and a few hours in the slow cooker. The pasta absorbs all the savory tomato flavor, and the cream cheese melts into a silky, luxurious sauce that clings to every bite.

It is perfect for busy weeknights, potlucks, or any time you need dinner on the table without a lot of fuss. Serve it with a crisp salad and some garlic bread, and watch it disappear before you can even sit down.

Why You’ll Love This Recipe

This recipe is the definition of hands-off comfort food. With just three main ingredients, it is budget-friendly, forgiving, and perfect for busy days when you want something warm without a lot of work.

The texture is unforgettable. The pasta cooks right in the sauce, becoming tender and flavorful, while the cream cheese creates a smooth, creamy finish that tastes far richer than three ingredients should allow.

It is also endlessly adaptable. Add protein, vegetables, or a pinch of spice, or keep it simple and let the creamy tomato sauce shine.

Ingredients

12 ounces penne, rotini, or bowtie pasta, uncooked
1 jar (24 ounces) marinara or pasta sauce
8 ounces cream cheese, softened and cubed

Water or broth is considered a free pantry staple. You will need about 3 cups. Salt and black pepper can be added to taste.

Directions

Lightly grease the inside of a 4- to 6-quart slow cooker.
Add the uncooked pasta, marinara sauce, and water or broth to the slow cooker. Stir to combine, making sure the pasta is mostly submerged.
Scatter the cream cheese cubes evenly over the top. Do not stir.
Cover and cook on LOW for 2 to 3 hours, or on HIGH for 1 to 1 1/2 hours, stirring every 30 minutes to prevent sticking.
Once the pasta is tender and the cream cheese has melted, stir everything together until the sauce is smooth and creamy.
Taste and season with salt and pepper. Serve hot.

Variations

Add 1 pound of cooked ground beef, Italian sausage, or shredded chicken during the last 30 minutes.
Stir in 2 cups of fresh spinach or steamed broccoli during the last 20 minutes.
Add a pinch of red pepper flakes or use spicy marinara for heat.
Swap the marinara for Alfredo sauce for an even creamier pasta.
Stir in 1 cup of shredded mozzarella or Parmesan at the end for extra cheesy goodness.
Use gluten-free pasta and adjust the cooking time as needed.

Expert Tips

Stir occasionally. Pasta can clump together in the slow cooker, so a quick stir every 30 minutes helps it cook evenly.
Watch the liquid. If the pasta seems dry, add a splash more water or broth. If it is too soupy, leave the lid slightly ajar for the last 15 minutes.
Use softened cream cheese. It melts more smoothly and creates a silkier sauce.
Do not overcook. Pasta can go from perfectly tender to mushy quickly. Start checking at the lower end of the cook time.
Use a good sauce. Since the sauce is a key flavor component, choose a brand you love.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave with a splash of milk or broth to loosen the sauce. This dish does not freeze well, as the pasta and cream cheese can separate upon thawing.
