One Pot Pesto Pasta with Chicken

Easy One Pot Pesto Pasta Guide

The smell of garlic hitting hot olive oil and the sudden burst of fresh basil is basically a hug in a pan. I used to think that to get a creamy pasta, I had to boil a giant pot of water, drain it into the sink, and then spend ten minutes whisking a separate sauce. It felt like a lot of work for a Tuesday night.

But here is the thing: draining your pasta water is actually a waste. That cloudy, salty water is full of starch, which is the very thing that makes restaurant sauces cling to the noodles. By cooking everything together, we keep that starch right where it belongs.

This One Pot Pesto Pasta relies on that simple trick to stay rich and glossy. You get the sear from the chicken and the brightness from the pesto, all without the usual mountain of pots and pans. It's a solid, reliable meal that doesn't taste like a shortcut.

What Makes This Work

• Pasta Starch: Since we don't drain the liquid, the starch from the penne mixes with the almond milk and pesto. This creates a natural thickening effect that coats every noodle.
• Low Heat Finishing: Pesto is a raw sauce. Adding it at the very end prevents the basil from turning brown and keeps the flavor bright.

For those who prefer different bases, you can find a similar vibe in my [Pasta Pesto Vegan](https://zegreenfood.com/recipes/pasta pesto-vegan/) version which swaps the dairy and meat for plant based alternatives.

Depending on what you are aiming for with your dinner, you can tweak the base easily.

The Recipe Basics

Right then, let's look at the numbers. This meal moves fast. You spend about 5 minutes chopping and seasoning, and the rest happens in the pan. The total time from start to finish is 20 minutes. It serves 4 people, making it a great family favorite.

The goal here is a balanced plate. You have the lean protein from the chicken, the fiber from the whole grain pasta, and the healthy fats from the olive oil and pesto. It's comfort food that actually feels good after you eat it.

Ingredient Deep Dive

I've noticed that whole grain pasta brings a nutty flavor that complements the bold basil. I also recommend the Greek yogurt, as its slight acidity cuts through the richness of the Parmesan.

For the Protein and Base

• 1 lb boneless, skinless chicken breast, cubed Why this? Lean protein that cooks rapidly
• 1 tbsp extra virgin olive oil Why this? Ideal for high heat searing
• 1 tsp garlic powder Why this? Provides a consistent coating
• 1/2 tsp salt Why this? Enhances overall flavor
• 1/2 tsp black pepper Why this? Gives a subtle kick

For the Simmer

• 12 oz whole grain penne Why this? Captures the sauce effectively
• 3 cups low sodium chicken broth Why this? Adds depth to the pasta
• 1/2 cup unsweetened almond milk Why this? Adds silkiness without heavy fats
• 1 cup halved cherry tomatoes Why this? Provides a fresh, acidic pop

For the Finishing Touch

• 1/2 cup basil pesto Why this? The primary flavor profile
• 1/4 cup grated Parmesan cheese Why this? Adds a salty, umami kick
• 2 tbsp plain Greek yogurt Why this? Adds thickness and a bit of tang
• fresh basil leaves for garnish Why this? Enhances aroma and presentation

Must Have Kitchen Tools

No specialized gear is necessary for this recipe. Either a Dutch oven or a deep skillet will work well, provided it has high enough sides to prevent the simmering pasta from splashing over.

I prefer using a 12 inch stainless steel skillet. This gives the chicken enough space to brown properly without crowding the pan, which would otherwise steam the meat instead of searing it. A lid is also essential here to trap the steam and ensure the pasta cooks evenly.

Step by step Cooking

Time to get started. Constant stirring is important to prevent the garlic from scorching and the pasta from clumping.

1. Warm the olive oil in a Dutch oven or deep skillet over medium high heat.
2. Toss in the diced chicken breast, garlic powder, salt, and pepper. Sauté for 4–6 minutes until the edges turn golden. Note: Avoid overcooking the meat since it will be heated again later.
3. Transfer the chicken to a plate and set it aside.
4. In the same vessel, combine the almond milk, chicken broth, and dried pasta.
5. Bring the mixture to a light boil, then lower the heat to a simmer.
6. Put the lid on and cook for 10–12 minutes, stirring every now and then. Continue until the pasta is al dente and the sauce has reduced by half.
7. Mix in the cherry tomato halves. Note: Adding these late prevents them from breaking down too much.
8. Add the browned chicken back into the pot.
9. Set the heat to low and stir in the Greek yogurt, Parmesan, and basil pesto.
10. Gently stir for 1–2 minutes until the sauce is smooth and clings to the pasta.
11. Take the pot off the heat immediately and garnish with fresh basil.

Pro Tip: For an extra kick, toss in some crushed red pepper while browning the chicken. This adds a mild warmth to the One Pot Pesto Pasta that complements the tangy yogurt.

Fixing Common Issues

Cooking in one pot can sometimes be a bit unpredictable since you can't just dump out the excess liquid. But most of these things are easy to fix on the fly.

Fixing Thin Sauce

If your pasta is cooked through but the pan still looks like a soup, don't panic. Just take the lid off and crank the heat up to medium high for about 2 or 3 minutes. Stir constantly. The remaining liquid will evaporate quickly, and the starch will concentrate, turning the sauce into a glossy glaze.

Fixing Dull Colors

Pesto can turn a muddy brown if it hits too much heat for too long. This happens because the basil is sensitive to high temperatures. To keep that bright green look, always turn your heat to low or off entirely before stirring in the pesto.

If it already turned brown, a handful of fresh chopped basil stirred in at the end can mask it.

Fixing Mushy Pasta

This usually happens if the simmer was too aggressive or the lid was too tight. If the noodles are too soft, the best fix is to stop cooking immediately. Don't let it sit in the hot pan. Transfer the One Pot Pesto Pasta to a bowl right away to stop the carryover cooking.

Flavor Twists and Swaps

This recipe is wonderfully versatile, allowing you to easily customize the flavor profile based on whatever you have in your fridge.

To create a "Savory Smoke" version, incorporate 4 oz of diced bacon or pancetta during the initial step. Sauté until crisp, then use that rendered fat to sear the chicken for a salty, smoky depth that makes the meal feel richer and more decadent.

For an extra boost of greens, toss in two handfuls of fresh baby spinach at the same time as the cherry tomatoes. The residual heat from the pasta will wilt the leaves in roughly 60 seconds, making it an effortless way to add nutrients to a family staple.

For a complete change of pace, you could use a Red Pesto Sauce instead. Utilizing sun-dried tomatoes, it provides a tangier and more concentrated flavor profile than the fresh basil version.

Storage and Waste Tips

This dish keeps quite well, though the sauce tends to thicken as it sits in the fridge. Store leftovers in a glass container for up to 3 days.

When you reheat it, the pasta will have absorbed most of the sauce. To bring it back to life, add a splash of water or a tablespoon of almond milk before microwaving. This loosens the starch and makes it creamy again.

I don't recommend freezing this specific recipe because the Greek yogurt and pesto can separate, leaving you with a grainy texture.

To avoid waste, don't throw away your basil stems. If you're making your own pesto, toss the stems into a freezer bag. Next time you make a homemade chicken broth, throw those frozen stems in the pot for a hit of herbal flavor.

The Best Side Pairings

Because the One Pot Pesto Pasta is quite indulgent, you'll want accompaniments that offer a bold contrast. Something bright or crunchy is ideal for refreshing the palate.

A zesty arugula salad tossed in lemon dressing is a classic choice. The peppery greens and citrus zing cut through the richness of the pesto and Parmesan, preventing the meal from feeling too heavy.

For a heartier option, roasted broccolini or asparagus finished with a squeeze of lime works beautifully. The charred flavor of the vegetables complements the seared chicken in the pasta.

Since the dish is already garlic forward, avoid garlic bread; instead, opt for a piece of charred sourdough rubbed with a fresh garlic clove for a lighter crisp.
