There’s something undeniably satisfying about a pasta dish that marries rich, creamy sauce with a bold spice kick—and that’s exactly what you get with these Creamy Cajun Chicken Stuffed Shells. Inspired by the hearty flavors of New Orleans, this recipe combines tender chicken seasoned with Cajun spices, jumbo pasta shells, and a velvety cheese sauce that clings to every curve and crevice. It’s the kind of meal that feels indulgent enough for weekend entertaining yet simple enough for a midweek family dinner.

I first tried this combination on a chilly evening when I craved both comfort and a little heat. The result was a stunning casserole of plump shells, each one cradling a bite of seasoned chicken, all enveloped in a luscious Monterey Jack–Parmesan sauce. A quick bake under a blanket of extra cheese takes it over the top, giving you a golden, bubbly finish that’s impossible to resist.

Whether you’re cooking for a crowd or simply want to elevate your go-to pasta night, these stuffed shells deliver on flavor, texture, and visual appeal. Below, you’ll find the full list of ingredients followed by the initial steps: seasoning and sautéing the chicken, cooking the shells, and beginning the sauce. In Part 2, we’ll complete the sauce, assemble the shells, and show you how to bake them to cheesy perfection.

Ingredients

For the Chicken & Seasoning

• 1 lb (450 g) boneless, skinless chicken breasts, cut into 1″ cubes
• 2 Tbsp Cajun seasoning
• 1 Tbsp olive oil
• Salt & pepper, to taste

For the Pasta & Sauce

• 12 oz (340 g) jumbo pasta shells
• 2 Tbsp unsalted butter
• 1 small yellow onion, finely diced
• 2 cloves garlic, minced
• 1 ½ cups heavy cream
• 1 cup low-sodium chicken broth
• 1 cup shredded Monterey Jack cheese
• ½ cup grated Parmesan cheese
• 1 Tbsp chopped fresh parsley (optional)

Steps

1. Season & Sauté the Chicken
   In a medium bowl, toss the chicken cubes with the Cajun seasoning, a pinch of salt, and a few grinds of black pepper. Heat the olive oil in a large skillet over medium-high heat. Add the seasoned chicken and sauté for 5–6 minutes, stirring occasionally, until the exterior is golden and the chicken is cooked through. Transfer the chicken to a plate and set aside.

1. Boil the Shells
   While the chicken cooks, bring a large pot of salted water to a rolling boil. Add the jumbo pasta shells and cook for 10–12 minutes, until just al dente. Drain the shells in a colander and transfer them to a lightly oiled tray or bowl to prevent sticking.

1. Start the Sauce
   Return the empty skillet to medium heat and melt the butter. Add the diced onion and sauté for 3–4 minutes, until it becomes translucent. Stir in the minced garlic and cook for an additional 30 seconds, taking care not to let it brown. You’ll notice the skillet filling with fragrant aromatics—this builds the foundation for your creamy sauce.

Crafting the Creamy Sauce and Assembling the Shells

With your chicken sautéed, shells cooked, and aromatics sizzling, it’s time to build the lush, cheesy sauce that makes this dish shine—and then bring everything together in a bubbling, irresistible bake. Follow these steps to transform simple ingredients into a showstopping entrée.

Steps

4. Add the Liquids
   Pour the heavy cream and chicken broth into the skillet with the onions and garlic. Stir gently to combine, scraping up any browned bits from the pan’s bottom. Bring the mixture to a gentle simmer over medium heat—small bubbles should break the surface without boiling vigorously.

4. Melt in the Cheeses
   Reduce the heat to low and whisk in the Monterey Jack and Parmesan cheeses a handful at a time. Continue stirring until the sauce is silky and smooth, with no visible strands of cheese. Taste and adjust seasoning with an extra pinch of Cajun spice or a dash of salt, if needed.
5. Combine Chicken and Shells
   Return the cooked chicken to the sauce, folding it in so each cube is coated. Then, gently transfer the drained pasta shells into the skillet, stirring just enough to nestle them into the sauce. You want each shell’s interior to catch a bit of sauce, even before baking.
6. Optional Bake for a Golden Finish
   If you prefer a broiled, bubbly top, preheat your oven to 375 °F (190 °C). Spoon the saucy shells into a lightly greased baking dish in a single layer. Sprinkle a little extra Monterey Jack over the surface, then bake for 10 minutes, until the cheese begins to bubble and turn a light golden hue. For extra color, switch to broil for 1–2 minutes—watching closely to prevent burning.

Helpful Variations and Tips

• Spicier Heat: Amplify the kick by stirring in ½ tsp of cayenne pepper or a few dashes of Tabasco into the sauce. A dusting of smoked paprika on top before baking adds an enticing smoky note.
• Vegetable Boost: Fold in 1 cup of finely chopped bell peppers, sautéed mushrooms, or baby spinach at Step 6. The veggies cook quickly in the sauce, adding color and nutrition.
• Creamier Indulgence: Swap half the heavy cream for mascarpone cheese. It melts luxuriously and adds a subtle tang that contrasts beautifully with the Cajun seasoning.
• Make-Ahead Shortcut: Complete through Step 5, then let the sauce cool slightly and refrigerate for up to 24 hours. When you’re ready, reheat gently, add chicken and shells, then bake as directed.
• Gluten-Free Option: Use gluten-free jumbo shells and verify your Cajun seasoning is gluten-free. Cook and assemble the same way, monitoring the bake closely since gluten-free pasta can become tender faster.
• One-Skillet Stove-Top Finish: If you want to skip the oven, cover the skillet after adding shells, reduce heat to low, and cook for 5 minutes. The trapped steam will melt the cheese on top—just remember to uncover and rest 2 minutes before serving.

FAQs and Conclusion

Q1: Can I prepare this dish ahead of time?
Yes. Complete through Step 5 (sauce preparation), then let the sauce cool, cover, and refrigerate for up to 24 hours. When you’re ready, reheat gently on the stove, stir in the chicken and shells, and proceed with the optional bake in Step 7.

Q2: What’s the best way to store and reheat leftovers?
Allow any leftovers to cool briefly, then transfer to an airtight container and refrigerate for up to 3 days. To reheat, warm in a 350 °F oven for 10 minutes, covered with foil to prevent drying, or microwave individual portions until heated through.

Q3: How can I control the heat level?
Reduce or omit the additional Cajun seasoning when adjusting the sauce’s seasoning. If you prefer more spice, stir in cayenne or a few dashes of hot sauce to taste, or choose a hotter Cajun blend at the outset.

Q4: Can I make this gluten-free or dairy-free?
For gluten-free, simply use certified gluten-free jumbo shells and verify that your Cajun seasoning contains no wheat. For a dairy-free version, substitute butter with olive oil, use coconut cream in place of heavy cream, and swap cheeses for plant-based alternatives—though the sauce’s texture will be slightly lighter.

Q5: Is it possible to turn this into a one-pan stovetop meal?
Yes. After combining the chicken, sauce, and shells in Step 6, cover the skillet, reduce heat to low, and cook for 5 minutes. The steam will melt the cheeses on top. Let rest for 2 minutes before serving.

Q6: How do I scale this recipe for a larger gathering?
The ingredients scale linearly—just double or triple quantities as needed. Use multiple skillets or transfer to larger baking dishes for the optional bake, and increase bake time by 5–10 minutes to ensure everything heats through.

Q7: Can I add vegetables or other proteins?
Absolutely. Fold in sautéed bell peppers, mushrooms, spinach, or even cooked and crumbled sausage when combining the sauce in Step 6. These additions will cook in the sauce and add color, texture, and extra nutrition.
