Slow Cooker 4-Ingredient Pasta Kensington

There are some dinners that feel like a warm hug from a vintage dinner party, and this Slow Cooker 4-Ingredient Pasta Kensington is exactly that. It is creamy, savory, and just a little bit elegant, with tender pasta, rich Italian sausage, and a velvety sauce that tastes like you spent hours at the stove. The slow cooker does all the work, and you are left with a meal that feels special enough for company but simple enough for a busy weeknight.

What I love most about this recipe is how the cream cheese melts into the sauce, creating a silky, luxurious texture that coats every piece of pasta. The Italian sausage adds a savory, slightly spicy depth, while the roasted red peppers bring a gentle sweetness and a beautiful pop of color. It is the kind of dish that makes everyone at the table go quiet for a moment, then reach for seconds.

It is also wonderfully versatile. You can use mild or hot sausage, add spinach or mushrooms, or swap the pasta shape to suit your preferences. Whether you are feeding a family or bringing a dish to a potluck, this pasta delivers comfort and flavor every single time.

Ingredients

12 ounces penne, rotini, or bowtie pasta, uncooked
1 pound Italian sausage, casings removed
8 ounces cream cheese, softened and cubed
1 jar (12 ounces) roasted red peppers, drained and sliced

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

Directions

Lightly grease the inside of a 4- to 6-quart slow cooker.
In a skillet over medium-high heat, brown the Italian sausage until cooked through, breaking it up as it cooks. Drain off excess grease.
Add the uncooked pasta, cooked sausage, roasted red peppers, 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 1½ 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, pepper, and garlic powder if needed. Serve hot.

Variations

Spicy Kensington: Use hot Italian sausage and add a pinch of red pepper flakes.
Spinach Kensington: Stir in 2 cups of fresh spinach during the last 15 minutes of cooking.
Mushroom Kensington: Add 1 cup of sliced sautéed mushrooms with the sausage.
Chicken Kensington: Swap the sausage for 2 cups of shredded cooked chicken.
Cheesy Kensington: Stir in 1 cup of shredded Parmesan or mozzarella at the end.
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 stirring every 30 minutes ensures even cooking.
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 cream cheese at the start: It melts into the sauce as the pasta cooks, creating a creamy texture without any extra steps.
Don’t overcook: Pasta can go from perfectly tender to mushy quickly. Start checking at the lower end of the cook time.
Use a good sausage: Since the sausage 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.
