Ingredients
For the Main Dish:
- 12 oz rotini pasta (about 3 cups dry)
- 2 tbsp butter
- 1 tbsp olive oil
- 1 medium onion, finely chopped (about 1 cup)
- 1 red bell pepper, diced
- 4 cloves garlic, minced
- 1 tbsp Cajun seasoning (adjust to taste)
- 1 tsp smoked paprika
- 1/4 tsp red pepper flakes (optional for extra heat)
- 1 cup low-sodium chicken broth (or vegetable broth)
- 1 cup heavy cream
- 4 oz cream cheese, cubed
- 2 cups shredded cheddar cheese (sharp works great)
- 1/2 cup grated Parmesan
- 2 tbsp lemon juice (about 1/2 lemon)
- 2 tbsp chopped fresh parsley for garnish
- Salt and black pepper to taste
- Optional: 1 lb cooked chicken or sliced smoked sausage, chopped (see notes)
For the Sauce / Garnish (if applicable):
- Extra chopped parsley, extra grated Parmesan, and a pinch more Cajun seasoning for serving.
How I Make It
Step 1:
Bring a large pot of salted water to a boil and cook the rotini until just shy of al dente (about 8–9 minutes). Drain, reserving about 1/2 cup pasta water — that starchy water saves a sauce more times than I can count. Toss the hot pasta with a drizzle of olive oil so the pieces don’t cling together while you make the sauce. The kitchen should already be smelling like warm, toasty pasta — comfort incoming.
Step 2:
In a large skillet over medium-high heat, melt 2 tbsp butter with 1 tbsp olive oil. Add the onion and red bell pepper; sauté until the onion turns translucent and the pepper softens, about 4–5 minutes. Hear that gentle sizzle? That’s flavor being built. Stir in the garlic, Cajun seasoning, and smoked paprika, and cook 30–45 seconds until fragrant — don’t let the garlic burn or it will taste bitter.
Step 3:
Pour in the chicken broth and scrape up any brown bits from the pan — that’s flavor gold. Add the heavy cream and bring everything to a gentle simmer. Lower the heat and whisk in the cream cheese until smooth. This sauce should start to thicken and smell rich and garlicky. If you added cooked protein, toss it in now so it heats through and soaks in the sauce.
Step 4:
Turn the heat to low and stir in the cheddar and Parmesan until melted and silky. Add the drained pasta and toss to coat, using a splash of reserved pasta water if the sauce seems too thick. Taste and adjust salt, pepper, and Cajun seasoning. You want a balanced heat that sings, not a one-note burn. The finished pasta should cling to the sauce and glisten like edible sunshine.
Step 5:
Finish with lemon juice and chopped parsley for brightness. Serve immediately with extra Parmesan and a sprinkle of parsley. Listen for the satisfied silence as people dig in — or the slightly dramatic “Mmm!” coming from your dining table. Leftovers reheat beautifully in a skillet over low heat with a splash of milk or broth.
Pro Tips
- For creamier sauce, warm the heavy cream slightly before adding so the cheese melts faster and avoids clumping.
- Use reserved pasta water sparingly — a tablespoon at a time — to loosen the sauce without making it watery.
- If you want a smoky boost, add a pinch more smoked paprika rather than extra Cajun seasoning; it deepens flavor without more salt.
- Make it ahead: toss pasta with sauce, refrigerate, then reheat gently on the stove with a splash of broth to revive the texture.
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 rotini for penne or rigatoni — the sauce clings to tubular shapes just as well.
- Replace heavy cream with full-fat coconut milk for a dairy-free twist; expect a slightly coconutty flavor.
- Use Greek yogurt (tempered) instead of some cream for a tangy, lighter version — stir in off heat to prevent curdling.
- For gluten-free, use your favorite gluten-free pasta and check cooking times; timing may vary.
- Omit cheese and use a dairy-free cheese alternative for a vegan/dairy-free option; the texture shifts but the spice still shines.
Variations & Tips
- Spicy: Add diced jalapeño with the onion and bump red pepper flakes to 1/2 tsp.
- Kid-friendly: Reduce Cajun seasoning to 1 tsp and skip the red pepper flakes.
- Meaty: Stir in browned Italian sausage or diced, seasoned chicken for heft.
- Veggie-loaded: Add zucchini and mushrooms with the peppers for extra veggies.
- One-pan bake: Transfer to a baking dish, top with extra cheddar, and broil 2–3 minutes until golden and bubbly.
- Creative twist: Add a spoonful of sun-dried tomato pesto for a tangy, umami lift.
FAQ (Frequently Asked Questions)
- Can I make this ahead of time?
- Yes! Assemble the pasta and sauce, cool, and refrigerate in an airtight container up to 2 days. Reheat in a skillet over low heat with a splash of broth or milk to loosen the sauce.
- Can I double the recipe?
- Sure thing. Use a larger pot and skillet and stir in the pasta in batches if needed. You may need a touch more broth or cream to keep the sauce velvety.
- Can I substitute butter with oil?
- Technically yes, but you’ll miss that buttery magic. Use ¾ the amount of oil and consider adding a pat of butter at the end for richness.
- How do I know it’s done?
- The sauce should coat the pasta and look glossy, cheese fully melted, and the pasta tender but slightly firm (al dente). If the sauce separates or looks grainy, lower the heat and whisk in a splash of broth.
- What if I don’t have ingredient X?
- Out of cream cheese? Use extra cream and a spoonful of Greek yogurt off-heat. No cheddar? Try Monterey Jack or Colby for similar meltability.
How I Like to Serve It
I love serving this on a cozy weeknight with a simple green salad and crusty bread to mop up the sauce. For a casual dinner party, add a charred lemon half and some extra parsley for color. It also plays well at potlucks — keep it warm in a slow cooker on low. Pair with a chilled lager or an unoaked Chardonnay to balance the creaminess and spice.
Notes
- Store leftovers in an airtight container up to 3 days. Reheat gently with a splash of broth or milk.
- If you add raw chicken, cook it to a safe internal temperature of 165°F before tossing with the pasta.
