Instant Pot Creamy Chicken Spaghetti
This creamy chicken spaghetti is a quick and comforting meal that pleases both kids and adults alike, cooked easily in the Instant Pot for a weeknight dinner.
I first made this Instant Pot Creamy Chicken Spaghetti on a hectic weeknight when I needed something fast, comforting, and un-fussy — and it delivered. It’s the kind of meal that reheats beautifully, pleases both kids and picky adults, and feels indulgent without a lot of hands-on time. If you want a dinner that checks the “quick,” “creamy,” and “crowd-pleaser” boxes, this recipe is a solid go-to; for an extra cozy menu, I sometimes serve it alongside a warm bowl of creamy crockpot chicken and wild rice soup on nights we want double comfort.
Why you’ll love this dish
This recipe shines because it compresses the flavors of a slow-simmered casserole into one pot and about 20–30 minutes of active time. Benefits at a glance:
- Fast: the Instant Pot does the heavy lifting so dinner is ready in under an hour from start to finish.
- Budget-friendly: uses simple pantry pasta, basic shredded or cubed chicken, and affordable dairy.
- Kid-approved: creamy texture and familiar flavors make it a hit with little eaters.
- Versatile: add veggies, swap proteins, or make it lighter with milk instead of cream.
How this recipe comes together
Quick overview so you know what to expect:
- Sauté aromatics and brown the chicken in the Instant Pot to build flavor.
- Add broth, canned tomatoes (if using), and broken spaghetti so the pasta is submerged.
- Pressure-cook briefly (short time to avoid overcooked pasta), then release pressure quickly.
- Stir in shredded cheese and cream to create a luscious sauce.
- Finish with fresh herbs and let it sit a minute to thicken before serving.
This method keeps the spaghetti tender but not mushy, and the short pressure time means the chicken stays moist.
What you’ll need
- 1 lb boneless skinless chicken breasts or thighs (cut into 1-inch pieces or use pre-cooked shredded chicken)
- 8–12 oz spaghetti, broken in half (8 oz for creamier, 12 oz if you want more pasta)
- 2 tbsp olive oil or butter
- 1 small onion, finely chopped
- 3 garlic cloves, minced
- 1 can (14.5 oz) diced tomatoes (optional — adds brightness)
- 3 cups low-sodium chicken broth (add more if using larger pot)
- 1 cup heavy cream or whole milk (milk yields a lighter sauce)
- 1–1½ cups shredded cheddar or Monterey Jack (or a blend)
- 1 tsp Italian seasoning
- Salt and pepper to taste
- Fresh parsley or basil for garnish
Notes/substitutions inline:
- Gluten-free: use GF spaghetti and check broth label.
- Dairy-free: replace cream with full-fat coconut milk and use a dairy-free cheese.
- For extra veggies: add sliced bell pepper or frozen peas after pressure release.
Step-by-step instructions
- Set the Instant Pot to Sauté and add oil. When hot, cook the onions until translucent, about 3 minutes. Add garlic and cook 30 seconds.
- Season chicken with salt, pepper, and Italian seasoning. Add to the pot and brown briefly—about 2–3 minutes—to add flavor. You’re not cooking through here.
- Pour in the chicken broth and scrape any browned bits from the bottom (deglazing prevents burn errors).
- If using diced tomatoes, stir them in now. Break the spaghetti in half and arrange it in an even layer in the liquid—do not stir.
- Lock the lid and set to High Pressure for 4 minutes (this is a good starting point for most brands of dry spaghetti and bite-sized chicken). If your chicken is frozen, cook on High for 8–10 minutes (see FAQ).
- When the cook time ends, perform a Quick Release immediately to avoid overcooked pasta.
- Open the lid, stir gently to loosen strands. Add cream and shredded cheese; stir until smooth and creamy. Check seasoning and adjust.
- Let sit for 2–3 minutes to thicken slightly. Garnish with herbs and serve.
Safety note: ensure hot food is handled carefully; chicken should reach 165°F (74°C) internal temperature before serving if pieces were larger—shredded or small pieces heat through quickly.

Storage and reheating tips
Refrigerate: Cool to room temperature, then store in an airtight container in the fridge for up to 3–4 days.
Reheat (stovetop): Rewarm gently over low heat with a splash of milk or broth, stirring to restore creaminess.
Reheat (microwave): Cover loosely and heat in 60-second intervals, stirring between, adding liquid if dry.
Freeze: Freeze in meal-sized portions for up to 2 months. Thaw overnight in the fridge before reheating for best texture.
Food-safety reminder: refrigerate leftovers within 2 hours of cooking and reheat to 165°F before eating.
Creative twists
- Tex-Mex: Use pepper jack, corn, black beans, and a squeeze of lime. Top with avocado and cilantro.
- Mushroom and spinach: Sauté mushrooms first, add baby spinach right after pressure release so it wilts but stays bright.
- Buffalo-style: Stir in buffalo sauce and blue cheese crumbles; serve with celery sticks.
- Vegetarian: Replace chicken with hearty roasted cauliflower or tofu and use vegetable broth.
Your questions answered
Can I use frozen chicken?
A: Yes, but increase pressure time and be cautious with pasta. Either cook frozen chicken first (8–10 minutes, natural release, shred, then add pasta and cook 4 minutes) or use thawed/precooked chicken in the one-pot method.
What if my pasta comes out mushy?
A: That usually means overcooked. Use the 4-minute high-pressure guideline and Quick Release. Different pasta brands vary; if you prefer al dente, reduce pressure time by 1 minute.
Can I double the recipe?
A: You can, but don’t overfill the Instant Pot. Leave space under the max fill line and increase liquid proportionally. If doubling, use two batches for consistent texture.
Is this freezer-friendly?
A: Yes — freeze in airtight containers up to 2 months. Thaw overnight and reheat gently, adding liquid if needed.
How can I make it lighter?
A: Swap heavy cream for half-and-half or whole milk and reduce cheese slightly; add more colorful veggies to bulk up the dish.
