Why This Recipe is Awesome

This Spicy Chicken Spaghetti gives you creamy, cheesy comfort with a lively kick — think silky sauce, pops of tomato, and a little heat that keeps you coming back for more. It cooks fast, uses pantry staples, and finishes under the broiler so you get crispy, golden edges. It’s so easy even your oven can’t mess it up. Plus, the contrast between tender shredded chicken and chewy spaghetti feels naughty and grown-up at the same time.

Ingredients

For the Main Dish:

• 12 oz spaghetti (regular or gluten-free)
• 1 lb boneless skinless chicken breasts (about 2 breasts) or 2 cups shredded rotisserie chicken
• 2 tbsp olive oil
• 1 medium yellow onion, diced (about 1 cup)
• 3 cloves garlic, minced
• 1 jalapeño, seeded and minced (or 1 tbsp chopped pickled jalapeños)
• 1 (10 oz) can diced tomatoes with green chiles (or regular diced tomatoes)
• 1 cup low-sodium chicken broth
• 8 oz cream cheese, softened
• 1/2 cup heavy cream (or plain Greek yogurt as swap)
• 1 cup shredded pepper jack cheese (or Monterey Jack + ½ cup cheddar)
• 1 tsp smoked paprika
• 1/2 tsp cayenne pepper (adjust to taste)
• 1 tsp dried oregano
• 1 tsp kosher salt (or to taste)
• 1/2 tsp black pepper
• 1 tbsp lime juice
• 2 tbsp chopped cilantro (for garnish)
• 2 tbsp sliced green onions (for garnish)
• Optional: crushed red pepper flakes for extra heat

For the Sauce / Garnish (if applicable):

• Extra shredded cheese for topping (about 1/2 cup)
• Lime wedges and extra cilantro for serving

How I Make It

Step 1:

Bring a large pot of salted water to a boil and cook the 12 oz spaghetti until al dente (usually 9–10 minutes). Reserve 1/2 cup pasta water, then drain. While the pasta cooks, heat 2 tbsp olive oil in a large skillet over medium-high heat. Season chicken with 1 tsp salt and pepper and add to the skillet. Sear until golden, about 4–5 minutes per side, and then cut into bite-sized pieces or shred. If you use rotisserie chicken, skip this searing step and save time.

Step 2:

Reduce heat to medium. Add the diced onion, minced garlic, and minced jalapeño to the skillet and sauté until soft and fragrant, about 4 minutes. Scrape the pan so browned bits mingle with the onions — that’s flavor. Toss in the canned diced tomatoes with green chiles, 1 cup chicken broth, smoked paprika, oregano, and cayenne. Bring the mixture to a simmer.

Step 3:

Lower the heat and stir in 8 oz cream cheese in chunks so it melts smoothly into the sauce. Add 1/2 cup heavy cream and 1 cup pepper jack cheese and stir until the sauce becomes glossy and silky. If the sauce feels too thick, add reserved pasta water a little at a time. Throw the cooked chicken back into the skillet and stir to coat — you’ll smell a tangy, creamy aroma that screams dinner is ready.

Step 4:

Add the drained spaghetti to the sauce and toss until each strand glistens. Taste and adjust seasoning with lime juice and extra salt if needed. Transfer everything to a baking dish, sprinkle extra cheese on top, and pop it under the broiler for 2–3 minutes until you get golden, bubbly spots. Watch closely so the top doesn’t burn.

Step 5:

Finish with a scatter of chopped cilantro and sliced green onions. Let the pasta rest for 3 minutes so the sauce sets up slightly. Serve with lime wedges and maybe a crisp salad on the side. That first spoonful should feel rich and tangy, with a little heat that lingers nicely.

Pro Tips

• Use rotisserie chicken when you’re short on time — it keeps this recipe under 30 minutes.
• Reserve pasta water before draining; the starchy water thins the sauce and helps it cling to noodles.
• For extra smoky depth, toast the smoked paprika briefly in the pan with the onions until it perfumes the kitchen.
• If you like a creamier finish, stir in an extra tablespoon of butter right at the end for glossy sauce.

Common Mistakes to Avoid

• Skipping preheating: Classic rookie move. It changes texture and bake time.
• Overmixing: Leads to dense or chewy results. Mix until just combined.
• Guessing cook time: Always use visual cues or a timer, not just vibes.
• Overcrowding pans: Give your food some breathing room to crisp properly.

Alternatives & Substitutions

• Swap chicken for firm tofu or tempeh for a vegetarian version; press and pan-sear tofu to add texture.
• Replace heavy cream with plain Greek yogurt (stir in off-heat) or coconut milk for a dairy-free twist — yogurt brightens, coconut adds sweetness.
• Use cheddar or Monterey Jack instead of pepper jack for milder flavor; add a pinch of chili flakes for heat if you lose the pepper jack.
• Choose gluten-free spaghetti to make the whole dish gluten-free; cooking time may vary slightly.

Variations & Tips

• Make it smoky: add 1/2 tsp chipotle powder and finish with a squeeze of lime.
• Kid-friendly: omit jalapeño and cayenne, swap pepper jack for mild cheddar.
• Mediterranean twist: swap tomatoes for sun-dried tomatoes and add olives and feta at the end.
• One-pot version: cook thin spaghetti broken in half directly in the sauce with extra broth, stirring often.
• Meal prep twist: lay leftovers in a casserole dish, top with cheese, and bake for 20 minutes to freshen up.
• Creative: fold in roasted corn and black beans for a Tex-Mex bake with more texture.

FAQ (Frequently Asked Questions)

Can I make this ahead of time?

Yes! Assemble the dish, cool completely, and refrigerate for up to 48 hours. Reheat covered in a 350°F oven for 15–20 minutes until warmed through, then broil briefly to re-crisp the top.

Can I double the recipe?

Sure thing. Use a larger skillet and a bigger baking dish; you may need to increase simmer time by 5–10 minutes so the sauce fully melds with the extra pasta and chicken.

Can I substitute butter with oil?

Technically yes, but you’ll miss that buttery magic. Use ¾ the amount of oil.

How do I know it’s done?

You’ll see glossy, bubbling sauce and golden cheese on top. Taste the chicken (or use an instant-read thermometer) — chicken reaches a safe internal temp at 165°F. The pasta should feel tender but still have a little bite.

What if I don’t have ingredient X?

Swap canned diced tomatoes for plain diced tomatoes plus 1 tsp chili powder; use Greek yogurt for heavy cream; use shredded rotisserie chicken if you lack fresh chicken breasts.

How I Like to Serve It

I love this Spicy Chicken Spaghetti with a crisp green salad and cold beer on a weeknight, or with buttery corn and lime wedges at a casual weekend dinner. It sits perfectly on a potluck table — people scoop it generous and go back for seconds. In winter it feels like a blanket, and in summer the lime and jalapeño keep it bright.

Notes

• Store leftovers in an airtight container for up to 3 days. Reheat gently to avoid separating the sauce.
• Safe cooking temp for chicken: 165°F. Use an instant-read thermometer for accuracy.
