Boursin Chicken Baked Ziti: 5-Ingredient Crockpot Dinner Step-by-step instructions

Before you start

Before you start, cut the chicken into bite-sized cubes and measure out the pasta, marinara, and seasonings. Have the Boursin wheel and shredded fontina ready. No need to pre-cook anything — the slow cooker does all the work.

If you have time, let the Boursin come to room temperature for easier melting. Make sure your slow cooker is clean and dry. This recipe is truly dump-and-go: the only prep is chopping the chicken and measuring the ingredients.

Instructions

Layer and Cover

1. 1Layer the Ingredients
   Place the cubed chicken breasts in the bottom of a 6-quart slow cooker. Spread them into an even layer. Add the ziti pasta directly over the chicken. Pour the marinara sauce over the pasta and chicken, then sprinkle with the Italian herb seasoning. Do not stir.
   Look for The ingredients should be in distinct layers, with the sauce covering the pasta and chicken.
   Tip Use a spatula to scrape every bit of marinara from the jar — it adds flavor and moisture.
2. 2Add the Cheeses
   Place the Boursin cheese wheel in the center of the slow cooker, pushing it slightly into the sauce. Scatter the shredded fontina evenly over the top. Cover the slow cooker with the lid.
   Look for The Boursin wheel sits in the middle, surrounded by the fontina shreds.
   Tip If the Boursin is cold, let it sit at room temperature for 10 minutes before adding — it will melt more evenly.

At the end of this phase, the slow cooker contains distinct layers: chicken at the bottom, ziti on top, then marinara sauce and herbs. The Boursin wheel sits in the center, and the fontina is scattered over the top.

The ingredients look colorful and appetizing, with the red sauce contrasting with the white cheeses. Nothing is stirred, and the slow cooker is ready to go.

Slow Cook and Check Temperature

3. 3Slow Cook Until Tender
   Cook on LOW for 3 to 4 hours, or on HIGH for 1 1/2 to 2 hours, until the chicken is cooked through and the pasta is tender. The sauce should be bubbling around the edges. Do not stir during cooking, as that can cause the pasta to clump.
   Look for The sauce is bubbling gently, and the cheese has melted into a creamy, golden layer.
   Safe temperature 165°F (74°C) internal temperature (poultry)
   Tip Resist the urge to lift the lid — every peek lets heat escape and adds cooking time.
4. 4Check the Chicken Temperature
   After the minimum cooking time, insert an instant-read thermometer into a few chicken cubes. The chicken is safe to eat when it registers 165°F (74°C). If it hasn't reached that temperature, cover and cook for 15 more minutes, then check again.
   Look for The thermometer reads 165°F (74°C) in the thickest piece of chicken.
   Safe temperature 165°F (74°C) internal temperature (poultry)
   Tip If the pasta is still firm but the chicken is done, let it sit covered for 5 minutes — residual heat will finish cooking the pasta.

After 3 to 4 hours on low, the kitchen smells of garlic, herbs, and tomato. The sauce is bubbling around the edges, and the cheese has melted into a creamy, golden layer. The chicken is cooked through and registers 165°F (74°C) on an instant-read thermometer. The pasta is tender and has absorbed much of the sauce. The texture is saucy but not soupy.

Stir, Rest, and Serve

5. 5Stir and Serve
   Once the chicken is cooked through, gently stir the mixture to combine the melted Boursin and fontina into the sauce. The sauce will become creamy and pinkish-orange. Let it rest for 5 minutes to thicken slightly.
   Look for The sauce is creamy and smooth, with melted cheese ribbons throughout.
   Tip Stir gently to avoid breaking the pasta — a wooden spoon works best.
6. 6Plate and Enjoy
   Spoon the Boursin chicken baked ziti onto warm plates. Serve immediately, making sure each portion gets some of the creamy sauce and melted cheese. The pasta will be tender, the chicken juicy, and the sauce rich and garlicky.
   Look for Each plate has a generous scoop of pasta, chicken, and creamy sauce.
   Tip For a golden top, place the slow cooker insert under the broiler for 2-3 minutes — but only if the insert is broiler-safe.

After stirring, the sauce is uniformly creamy and tinted pink from the Boursin. The pasta is coated in a rich, cheesy sauce, and the chicken pieces are tender and juicy. The dish has the consistency of a baked pasta casserole, with the sauce clinging to every bite. Portions spoon out easily, and the cheese stretches slightly as you serve.

Common mistakes

One common mistake is stirring the pot during cooking — this can break the pasta and make it gummy. Another is lifting the lid to check on it, which lets out heat and extends cooking time. If you use a slow cooker that runs hot, check the dish at the minimum time.

Also, don't add extra liquid: the marinara and the moisture from the chicken are enough to cook the pasta. If the sauce seems too thin at the end, let it sit uncovered for 10 minutes to reduce.

How to tell it’s done

The dish is done when the chicken reaches 165°F (74°C) on an instant-read thermometer and the pasta is tender but still holds its shape. The sauce should be bubbling gently around the edges, and the cheese should be fully melted and creamy.

If the pasta is still al dente after the chicken is done, let the pot sit covered for 5-10 minutes — residual heat will finish cooking it. The sauce will thicken slightly as it rests.
