Crockpot Kielbasa Pesto Farfalle: 5-Ingredient Dump Dinner

Imagine coming home to the aroma of smoked kielbasa and basil pesto wafting from the kitchen, with a creamy, cheesy pasta dinner ready to scoop onto plates. This Crockpot Kielbasa Pesto Farfalle is that dream come true.

With just five ingredients and five minutes of prep, you can set the slow cooker and forget about it until dinner. The sausage infuses the pasta with smoky flavor, while the pesto and cheeses create a rich, velvety sauce that clings to every bow-tie.

This recipe is the epitome of dump-and-go cooking. Layer sliced smoked kielbasa, uncooked farfalle, fresh spinach, basil pesto, ricotta, and provolone in the slow cooker, then walk away. Over four hours on low, the pasta absorbs the savory juices, the spinach wilts into the sauce, and the cheeses melt into a creamy, bubbling blanket.

The result is a hearty, Italian-inspired pasta bake that tastes like you simmered it all day—but with almost no work. Perfect for busy weeknights, this dish is a crowd-pleaser that requires zero stirring and minimal cleanup. Serve it straight from the crock or plate it for a prettier presentation.

Ingredients

Why this recipe works

The slow cooker acts as a gentle, even heat source that cooks the pasta and sausage together without constant attention. The uncooked pasta absorbs the moisture from the pesto, ricotta, and the sausage's natural juices, becoming tender and flavorful. The layers create distinct pockets of flavor that meld during the long, slow cook, resulting in a cohesive dish where every bite is balanced.

Using smoked kielbasa means the protein is already fully cooked, so it only needs to warm through and infuse the dish with its smoky, savory character. This removes the risk of undercooked meat and allows the slow cooker to focus on softening the pasta and melding the cheeses.

The combination of ricotta and provolone provides creaminess and a salty, stretchy finish, while the pesto adds a bright, herbal note that cuts through the richness.

Notes and substitutions

Choose a good-quality smoked kielbasa (often labeled Polish sausage) for the best flavor. It's available in the refrigerated meat section of most supermarkets. For the pasta, use a short shape like farfalle, penne, or rigatoni that holds up well to slow cooking. Do not use fresh pasta, as it will become mushy. The spinach adds color and nutrients, and it wilts down dramatically, so don't worry about the volume.

Prepared basil pesto is convenient, but if you have homemade pesto, even better. Just ensure it's not too oily, as the slow cooker retains all liquid. Whole-milk ricotta gives the creamiest texture; part-skim works but may be slightly less rich.

Shredded provolone melts beautifully; you can substitute mozzarella or a Italian cheese blend. This recipe is easily scaled for a smaller slow cooker—just adjust the amounts.

• smoked kielbasa: Smoked turkey sausage or andouille sausage (cooked) can be used; adjust seasoning.
• farfalle pasta: Penne, rigatoni, or other short pasta shapes work well; adjust cooking time if needed.
• basil pesto: Use sun-dried tomato pesto or a dairy-free pesto to change the flavor profile.
• whole-milk ricotta: Part-skim ricotta or cottage cheese (blended smooth) can substitute for a lighter texture.
