Slow Cooker Cheesy Chicken Penne

Category: Satisfying Main Dishes

This hearty dish brings together succulent chicken breasts slowly cooked in a creamy, cheesy sauce with penne pasta. Mushrooms and sweet onions infuse an earthy and mild sweetness, while tarragon offers a subtle herbaceous touch. The slow cooker method allows the chicken to become tender and rich, lightly shredded before stirring in sour cream and cheddar cheese, creating a luscious coating for the pasta. Finished with a cheesy melt on top, this comforting combination is ideal for satisfying family dinners or busy weeknights.

Serve alongside a fresh salad or garlic bread for a complete meal experience. Leftovers reheat well, with options to store refrigerated or frozen, maintaining the sauce’s creamy texture. Enhancements like sautéed mushrooms and onions or swapping cheddar for Monterey Jack offer variations to suit personal tastes.

Slow Cooker Cheesy Chicken Penne is the meal I turn to when everyone in my house craves comfort food and I do not want to be tied to the stove. It is creamy and filling and the slow cooker does most of the heavy lifting. The chicken turns tender and the cheesy sauce hugs every bite of pasta. The best part is how the flavors develop together so every serving feels warm and inviting.

I first made this on a Monday when we all came home tired. It made the kitchen smell amazing while it cooked and everyone asked for seconds.

Tarragon is probably my favorite touch here it reminds me of eating herby chicken casseroles at my grandmother's table when I was a kid. Every time I open the lid and get a whiff I am right back at her kitchen counter beside her.

Storage Tips

If you have leftovers store them airtight in the fridge for up to three days. The pasta may absorb sauce as it sits so add a little splash of broth or milk when reheating to bring back creaminess. To freeze cool the cheesy chicken penne fully and pack into freezer proof containers. Thaw overnight in the fridge then reheat slowly on the stovetop or microwave for best results.

Ingredient Substitutions

If you do not have tarragon dried Italian herbs or thyme work beautifully and give their own spin. For the cheese Monterey Jack or mozzarella can swap for cheddar and offer mild or melty results. Any small pasta like rotini or shells will do if penne is not handy just boil to al dente. Greek yogurt stands in well for sour cream for some extra tang.

Serving Suggestions

This dish shines on its own but it pairs so well with crispy garlic bread or a fresh green salad tossed with vinaigrette. Sometimes I scatter chopped parsley or basil on top for color and a pop of freshness. If making for a special meal a side of roasted vegetables rounds things out perfectly.

Recipe FAQs

Yes, Monterey Jack or mozzarella work well and provide a different flavor and texture.

→ Is it better to cook the pasta separately or in the slow cooker?

Cooking pasta separately prevents it from becoming mushy and helps it retain the perfect al dente texture.

→ What herbs complement the creamy sauce best?

Tarragon offers a subtle herbaceous note, but thyme, oregano, or Italian seasoning are excellent alternatives.

→ How can I deepen the mushroom and onion flavors?

Sautéing mushrooms and onions in olive oil before adding them enhances their richness and depth.

Steps

Step 01

In the slow cooker, mix the two cans of cream of chicken soup with 120 ml chicken broth until smooth and uniform.

Step 02

Stir in dried tarragon and ground black pepper, followed by sliced mushrooms and diced sweet onion. Place chicken breasts into the mixture, ensuring they are fully submerged.

Step 03

Cover and cook on low heat for 6 hours without opening the lid to allow the chicken to become tender and infused with flavors.

Using two forks, shred the cooked chicken breasts directly in the slow cooker until tender and evenly pulled apart.

Step 06

Mix in sour cream and half of the shredded cheddar cheese into the slow cooker until the sauce reaches a creamy consistency.

Step 07

Add the drained penne pasta to the slow cooker and stir to coat uniformly. Sprinkle the remaining cheddar cheese on top, cover, and cook on low for an additional 20 minutes to melt the cheese.

Once cheese has fully melted and the dish is heated through, serve hot. Optionally garnish with fresh herbs for presentation.

Notes

  1. For deeper flavor, sauté onions and mushrooms in olive oil before adding. Cheese varieties like Monterey Jack or mozzarella can substitute cheddar. Use fresh herbs like thyme or rosemary to enhance taste.
  2. Leftovers can be refrigerated up to 3 days or frozen for 3 months. Reheat with added broth or milk to loosen sauce if needed.
