How to Make Pesto Chicken Chili Mac Recipe
Step 1: Prepare the Pasta
First, bring a large pot of salted water to a boil and cook your pasta according to the package instructions until it’s just al dente. This is important because the pasta will finish cooking in the sauce later, absorbing even more flavor without becoming mushy. Once done, drain and set aside so it’s ready to join the flavorful mix.
Step 2: Sear the Chicken
Heat olive oil in a large Dutch oven or deep skillet over medium-high heat. Add the diced chicken seasoned with salt and pepper, and sauté until the pieces are golden brown and cooked through, about 5 to 6 minutes. This step locks in the juices and creates a delicious crust that will add texture to the finished dish. Once cooked, transfer the chicken to a plate and set it aside.
Step 3: Build the Sauce Base
Using the same pot, toss in the diced onion and red bell pepper. Cook them until they soften and become fragrant, approximately 4 minutes. Next, stir in the minced garlic and cook for an additional minute to ensure the flavors really bloom and meld beautifully.
Step 4: Bloom the Aromatics
Now, add the chopped sun-dried tomatoes, Italian seasoning, and red pepper flakes if you’re using them. Let these ingredients cook together for a minute to release their bold flavors, enriching the base and setting the stage for the chili magic to come.
Step 5: Create the Chili Base
Pour in the canned diced tomatoes with their juice and the chicken broth. Bring this savory mixture to a gentle simmer, allowing the flavors to marry and the juices to reduce slightly while becoming richer and more complex.
Step 6: Combine Components
Return the cooked chicken back into the pot, then add the drained pasta and the prepared basil pesto. Give everything a good stir to coat the noodles and chicken with the vibrant pesto-infused sauce. Let it simmer gently for 3 to 4 minutes so all the flavors meld perfectly together. Taste and adjust seasoning with salt and pepper as needed.
Step 7: Finish with Cheese
Remove the pot from heat and stir in the shredded mozzarella and grated Parmesan cheeses. The heat will melt the cheeses into a creamy, luscious layer that ties the whole dish together with a fantastic richness you won’t be able to resist.
Step 8: Plate and Serve
Serve your Pesto Chicken Chili Mac Recipe hot, garnished with extra pesto or a sprinkle of Parmesan for that final flourish. Each mouthful promises a comforting, cheesy, herbaceous bite that will leave you smiling.

Garnishes
For a fresh pop of color and flavor, sprinkle chopped fresh basil or a few basil leaves on top. A light drizzle of extra pesto adds a vibrant green touch and enhances the herbal notes. Don’t forget a grinding of fresh black pepper for a hint of spice, and extra Parmesan cheese if you’re feeling indulgent.
Side Dishes
This dish is hearty enough to stand on its own, but it also pairs beautifully with a crisp green salad tossed in a simple lemon vinaigrette to balance the richness. Garlic bread or warm focaccia is fantastic for soaking up any leftover sauce, making every bite count.
Creative Ways to Present
If you want to impress guests or mix things up, serve this chili mac in individual mini cast-iron skillets or ramekins for a rustic, cozy touch. You could also offer an assortment of toppings like sliced olives, chopped sun-dried tomatoes, or even a dollop of sour cream for guests to customize their bowls.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer your leftovers to an airtight container and refrigerate. The Pesto Chicken Chili Mac Recipe holds its flavor well for up to 3 days, making it a perfect next-day lunch or quick dinner option.
Freezing
If you want to make a batch in advance, freeze the dish in a freezer-safe container. For best results, consume within 2 months. Keep in mind that the texture of the cheese might change slightly after freezing, but the flavors remain just as delicious.
Reheating
To reheat, warm the chili mac gently on the stovetop over medium-low heat, stirring occasionally. You can add a splash of chicken broth or water to loosen the sauce if it looks thick. Alternatively, microwave in intervals, stirring between, until piping hot throughout.
FAQs
Can I use other types of pasta in the Pesto Chicken Chili Mac Recipe?
Absolutely! While elbow macaroni or small shells are ideal for holding the sauce, penne, rotini, or even fusilli would work wonderfully if you prefer a different texture or shape.
Is this dish spicy? Can I make it milder?
The crushed red pepper flakes add a gentle heat, but they are optional. If you prefer a milder dish, simply omit them. The pesto and sun-dried tomatoes provide plenty of vibrant flavor on their own.
Can I substitute the chicken with another protein?
Yes! Shrimp or Italian sausage both make delicious alternatives. Just adjust cooking times accordingly to ensure your protein is cooked through and tender.
Is this recipe suitable for meal prepping?
Definitely. The Pesto Chicken Chili Mac Recipe stores well and is just as satisfying when reheated. Preparing it in advance saves time and means you always have a delicious meal ready to go.
Can I make my own pesto for this recipe?
Homemade pesto is fantastic if you have the time and fresh basil on hand! It gives the dish an extra burst of freshness. However, store-bought pesto works beautifully and makes this recipe quick and easy to pull together.
Final Thoughts
This Pesto Chicken Chili Mac Recipe is one of those joyful dishes that feels like a warm hug after a long day.
