Before you start
Before starting, brown the Italian sausage in a large skillet over medium-high heat, breaking it into crumbles, until no longer pink. Drain any excess fat and set aside. Measure out the farfalle, spinach, pesto, and fontina.
Have the Boursin wheel ready at room temperature for even melting. Ensure your slow cooker is clean and dry, and keep the lid handy. This recipe requires about 10 minutes of prep, then the slow cooker does the rest.
Ingredients at a glance (6)
- 1 lb browned sweet Italian pork sausage crumbles
- 8 oz bow-tie farfalle pasta
- 4 cups fresh baby spinach leaves
- 1/2 cup Genovese basil pesto
- 1 wheel garlic-and-fine-herbs Boursin cheese
- 1 1/2 cups shredded Italian fontina cheese
Instructions
Layer and Go
- Layer the IngredientsPlace the browned sweet Italian sausage crumbles in an even layer at the bottom of a 6-quart slow cooker. Scatter the farfalle pasta over the sausage, then add the fresh baby spinach leaves. Spoon the basil pesto over the spinach and pasta, spreading it as evenly as possible.Look for The slow cooker should have a colorful layer of sausage, pasta, spinach, and green pesto.Tip No need to stir yet; the layers will meld during cooking.
- Add the CheesesPlace the wheel of garlic-and-fine-herbs Boursin cheese in the center of the slow cooker. Sprinkle the shredded Italian fontina cheese evenly over the top, covering the Boursin and the other ingredients.Look for The top should look like a blanket of shredded cheese with the Boursin wheel peeking through.Tip Leave the Boursin whole; it will melt and create a creamy sauce as it cooks.
At the end of this phase, the slow cooker contains distinct layers of sausage, pasta, spinach, pesto, and cheese. The colors are vibrant, with the green pesto and spinach contrasting against the white cheese.
The sausage crumbles are evenly distributed at the bottom. There is no need to stir; the layers will meld during cooking. The slow cooker is covered and ready to turn on.
Slow Cook to Creamy
- Cook on LowCover the slow cooker with its lid and cook on low for 3 to 4 hours, until the pasta is tender and the cheese is fully melted and bubbling. Do not open the lid during the first 2 hours to keep the heat steady.Look for The sauce should be bubbling gently around the edges and the cheese fully melted.Safe temperature 160°F (71°C) internal temperature (ground meat)Tip If the pasta absorbs too much liquid, add a splash of warm water or broth after 3 hours.
- Stir and CheckAfter 3 hours, remove the lid and stir the mixture well, ensuring the Boursin is fully incorporated into a creamy sauce. Check that the pasta is cooked al dente and the sausage is heated through. If needed, cover and cook for another 30 minutes.Look for The sauce should be silky and coat the pasta evenly, with no dry spots.Safe temperature 160°F (71°C) internal temperature (ground meat)Tip Taste a piece of pasta to check for doneness; it should be tender but still have a slight bite.
After 3 to 4 hours, the slow cooker is bubbling gently around the edges. The cheese has melted into a creamy, golden sauce, and the spinach has wilted into the mixture. The aroma is rich with garlic, herbs, and savory sausage. The pasta looks tender and is coated with the sauce. A quick stir reveals a smooth, cohesive dish with no dry pockets.
Scoop and Serve
- Serve HotSpoon the creamy pasta onto a warm serving plate or bowl. Use a large serving spoon to lift the pasta from the slow cooker, letting any extra sauce drip back. Serve immediately while hot and bubbling.Look for The pasta should be glossy with sauce, and the cheese should stretch as you scoop.Tip For an extra touch, sprinkle with fresh basil or cracked black pepper before serving.
The finished dish is glossy and creamy, with the sauce clinging to every piece of pasta. The sausage crumbles are juicy and evenly distributed. The cheese stretches as you scoop, and the steam rises with a fragrant herbal aroma. The pasta is tender but holds its shape. Serve immediately on warm plates for the best texture and flavor.
Common mistakes
One common mistake is opening the slow cooker lid too often, which releases heat and extends cooking time. Resist the urge to peek for the first 2 hours. Another is using too much liquid; the spinach and pesto provide enough moisture, so avoid adding extra water unless needed.
Overcooking can turn the pasta mushy, so check at the 3-hour mark. Finally, don't skip browning the sausage; it adds depth of flavor that you won't get from raw sausage.
How to tell it’s done
The dish is done when the pasta is tender but still holds a slight bite, and the sauce is creamy and bubbling. The sausage should be fully cooked, reaching an internal temperature of 160°F (71°C).
To check, insert an instant-read thermometer into a piece of sausage; it should register at least 160°F. The cheese should be completely melted and the spinach wilted into the sauce. If the pasta is still firm, cover and cook for another 15-20 minutes.
- Ground meat: 160°F (71°C) in the thickest part
