Ideal for busy weeknights or when you crave something warm and filling. This is one-pot cooking at its best.

Ingredients for Chicken Macaroni

Everything for this hearty one-pot comes together in your pantry and fridge.

The chicken quality matters here. Air-chilled, hormone-free breasts from Whole Foods or Costco yield the most tender results. For the cheddar, block cheese shredded at home melts smoother than pre-shredded (which contains anti-caking agents). The macaroni should be standard elbow—Barilla or De Cecco hold their shape well during the one-pot cooking process.

No whole milk? Half-and-half mixed with water at a 1:1 ratio works, though the sauce will be slightly richer. Swap cheddar for Colby Jack or Monterey Jack for a milder flavor. The Dijon can be replaced with whole-grain mustard at the same amount. For gluten-free, use brown rice flour and gluten-free pasta—just check cooking times, as they may vary.

Leftovers keep beautifully. Store in an airtight container for up to 4 days in the fridge or freeze for 2 months. Reheat gently on the stove with a splash of milk to restore creaminess (the microwave can make it separate).

Step-by-Step Instructions for Chicken Macaroni

This one-pot method ensures maximum flavor with minimal cleanup and effort.

Step 1: Sear the Chicken and Aromatics

Begin by heating the 3 tbsp unsalted butter in a large Dutch oven over medium-high heat. When the butter stops foaming, add the 1.5 lb boneless skinless chicken breasts cut into 1-inch pieces. Season with 1.5 tsp kosher salt and 0.5 tsp ground black pepper, then sear for 5-6 minutes until the exterior turns golden brown.

Remove the chicken and set aside. In the same pot, add the finely diced yellow onion and cook for 3-4 minutes until translucent. Stir in the minced garlic cloves and 0.5 tsp dried thyme, cooking for 30 seconds until fragrant. This builds the aromatic foundation for your dish.

Step 2: Build the Creamy Sauce Base

Sprinkle the 3 tbsp all-purpose flour over the onion mixture and stir constantly for 1-2 minutes to cook the raw flour taste out. This creates a smooth roux that will thicken your sauce beautifully.

Gradually whisk in the 2 cups chicken broth and 2.5 cups whole milk, ensuring no lumps form. Stir in the 1 tbsp Dijon mustard, which adds a subtle tang that balances the richness. Bring to a gentle simmer and cook for 3-4 minutes until the sauce begins to thicken slightly.

Step 3: Combine and Simmer to Perfection

Return the seared chicken to the pot along with the 8 oz elbow macaroni. Stir everything together, ensuring the pasta is fully submerged in the liquid. Bring to a boil, then reduce heat to medium-low.

Cover and simmer for 12-15 minutes, stirring occasionally, until the macaroni is al dente and the chicken is cooked through (internal temperature should reach 165°F). The pasta absorbs the creamy sauce as it cooks, creating a cohesive dish.

Step 4: Finish with Cheese and Serve

Remove from heat and stir in the 2 cups sharp cheddar cheese and 0.5 cup Parmesan cheese until fully melted and smooth. The residual heat is enough to create a velvety, rich sauce that coats every piece of pasta and chicken.

Let the dish rest for 5 minutes before serving to allow the sauce to thicken further. The cheeses should create a glossy, stretchy texture that’s irresistibly comforting. Serve warm, as the flavors meld best when freshly prepared.

Make-Ahead Tips for chicken macaroni

Prep Ahead Strategy

You can chop the yellow onion and mince the garlic cloves up to 2 days ahead. Store them in separate airtight containers in the fridge. This saves valuable time when you’re ready to cook. 💡

Chicken Prep

The 1.5 lb boneless skinless chicken breasts can be cut into 1-inch pieces and refrigerated for up to 24 hours before cooking. I like to keep them in a sealed container with a paper towel to absorb any moisture.

Cheese Grating

Shred the 2 cups sharp cheddar and 0.5 cup Parmesan the night before and store in the fridge. Freshly grated cheese melts better than pre-shredded, and doing this ahead makes the cooking process smoother.

Full Assembly Option

For true make-ahead convenience, assemble the entire dish up to the cheese addition. Cover and refrigerate for up to 12 hours. When ready, bring to a simmer and finish with the cheese. The pasta may absorb more liquid, so add ½ cup extra broth if needed. ⏰

Freezer Friendly

This dish freezes beautifully for up to 2 months. Portion into airtight containers and thaw overnight in the fridge. Reheat gently on the stove with a splash of milk to restore creaminess.
