Description

Welcome, pasta lovers! This Slow Cooker Creamy Chicken Tetrazzini takes the classic baked casserole and adapts it for a hands-off slow cooker. The result is a rich, velvety sauce combined with tender chicken, perfectly cooked pasta, and bright vegetables for balance. It’s ideal for busy weeknights or lazy weekends when you want a comforting, family-friendly meal with minimal fuss. Serve with garlic bread or a crisp green salad to round out the plate.

Ingredients

Make this creamy, comforting tetrazzini with the following:

• 1.5 lbs boneless, skinless chicken breasts
• Salt and pepper, to taste
• 1 medium onion, chopped
• 2 cloves garlic, minced
• 1 tsp Italian seasoning
• 2 cups chicken broth
• 1 cup cream of mushroom soup
• 1/2 cup white wine (optional — substitute more broth if you prefer)
• 1 cup heavy cream
• 12 oz spaghetti noodles, broken in half
• 1/4 cup grated Parmesan cheese
• 1/4 cup sour cream
• 1 cup frozen peas, thawed
• 1 cup sliced mushrooms

Notes: You can easily adapt this recipe—use gluten-free pasta for dietary needs, swap wine for extra broth, add extra vegetables (zucchini or bell peppers work well), or use leftover roasted turkey instead of chicken.

Instructions

Step 1: Prepare the Ingredients

1. Season the chicken breasts with salt and pepper and place them in the slow cooker.
2. Add the chopped onion, minced garlic, Italian seasoning, chicken broth, cream of mushroom soup, and white wine (if using) to the slow cooker. Stir gently to combine.

Step 2: Slow Cook

3. Cover and cook on low for about 4 hours, or until the chicken is cooked through and tender.

Step 3: Shred the Chicken

4. Remove the chicken from the slow cooker, shred it with two forks, then return the shredded chicken to the cooker and stir to mix with the sauce.

Step 4: Add Pasta and Creamy Ingredients

5. Stir in the heavy cream, broken spaghetti, grated Parmesan, and sour cream. Make sure the pasta is submerged in the liquid so it cooks evenly. If needed, add a splash more broth to cover the pasta.

Step 5: Finish with Veggies

6. Cook for another 30–60 minutes on low, or until the pasta is tender. Add the peas and sliced mushrooms during the last 10 minutes of cooking so they remain bright and fresh.

To Serve

Stir well, adjust seasoning to taste, and top with extra grated Parmesan. Serve hot with a simple salad or crusty bread.

Helpful Tips

• Keep pasta tender: Add the noodles later in the cooking process to prevent them from becoming mushy.
• Fresh produce: Use fresh garlic, onions, and mushrooms when possible for brighter flavor.
• Slow cooker size: Use a 6-quart slow cooker or larger to avoid overcrowding and to ensure even cooking.
• Consistency: If the final sauce is too thin, remove the lid and cook on high for a short time to reduce; if too thick, thin with a little extra broth or cream.
• Make it ahead: Prepare through the shredding stage, refrigerate, then add pasta and finish cooking when you’re ready to serve.

Serving Suggestions

Chicken Tetrazzini pairs beautifully with a crisp green salad, roasted vegetables, or garlic bread. A light white wine, such as Chardonnay, complements the creamy sauce if you serve alcohol. For a lighter meal, serve smaller portions alongside a simple tossed salad.

Frequently Asked Questions

Can I make this without cream of mushroom soup?

Yes. Substitute the soup with an equal amount of heavy cream combined with a little extra seasoning and a tablespoon of butter for richness.

What can I use instead of chicken?
