Slow Cooker 3-Ingredient Pasta Kingsley

There are some dinners that feel like a warm hug from a vintage community cookbook, and this Slow Cooker 3-Ingredient Pasta Kingsley is exactly that. It is creamy, savory, and wonderfully hands-off, with tender pasta coated in a rich pesto-cream sauce that tastes like you spent hours at the stove.

What I love most about this recipe is how effortlessly it comes together. The slow cooker does the work of cooking the pasta and creating a silky sauce, while the pesto goes in at the end so it stays bright and flavorful. It is the kind of meal that makes a busy weeknight feel a little more special and turns simple pantry staples into something everyone at the table will love.

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 dish 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 rich and satisfying. The pasta becomes tender and flavorful, while the cream cheese melts into a velvety sauce that clings to every bite. The pesto adds a fresh, savory finish that keeps the whole dish from feeling too heavy.

It is also endlessly adaptable. You can add chicken, spinach, sun-dried tomatoes, or a pinch of red pepper flakes, or keep it simple and let the pesto-cream sauce shine.

Ingredients

12 ounces penne, rotini, or bowtie pasta, uncooked
1 jar (8 ounces) basil pesto
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. Optional: grated Parmesan, cherry tomatoes, or fresh spinach.

Directions

Lightly grease the inside of a 4- to 6-quart slow cooker.
Add the uncooked pasta and 3 cups 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 in the pesto until the sauce is smooth and creamy.
If using Parmesan, cherry tomatoes, or spinach, stir them in during the last 5 to 10 minutes.
Taste and season with salt and pepper. Let rest for 5 minutes before serving.

Variations

Chicken Kingsley: Add 2 cups shredded cooked chicken during the last 30 minutes.
Sun-Dried Tomato Kingsley: Stir in 1/2 cup chopped sun-dried tomatoes with the pesto.
Spicy Kingsley: Add a pinch of red pepper flakes or a dash of hot sauce.
Alfredo Kingsley: Swap the pesto for a jar of Alfredo sauce for an even creamier pasta.
Vegetable Kingsley: Fold in fresh spinach, peas, or roasted red peppers during the last 10 minutes.
Gluten-Free: 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.
Add pesto at the end. This keeps its color and flavor bright.
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.

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.
