Ingredients
You don’t need anything fancy for this recipe. Most of it comes together with fresh produce and pantry staples.
The squash and zucchini are the star vegetables here, and they cook quickly, so you want pieces that are similar in size for even cooking.
Fresh lemon juice makes a real difference over bottled, so use it if you can.

- 2 medium yellow summer squash, sliced into half-moons
- 2 medium zucchini, sliced into half-moons
- 4 garlic cloves, minced

Kitchen Equipment Needed
You really only need a large skillet and a few basic tools for this recipe.
A 12-inch skillet gives you enough surface area to sear the chicken properly without crowding the pan, which is key to getting good color.
A sharp knife makes the prep work much faster, especially when slicing through squash.
- 12-inch nonstick or stainless steel skillet
- Sharp chef’s knife
- Cutting board
- Measuring spoons
- Wooden spoon or silicone spatula
- Citrus juicer or reamer
- Tongs
- Paper towels (for patting chicken dry)
- Zester or microplane (for lemon zest)
Recommended Products for This Recipe
These are products I personally reach for when making this dish, and they genuinely make a difference.
1. Lodge 12-Inch Cast Iron Skillet
A cast iron skillet gets hotter and holds heat more evenly than most nonstick pans, which means a better sear on the chicken every single time.
It goes from stovetop to oven seamlessly if you ever want to finish the dish under the broiler. This is an investment piece that will last you decades.
2. OXO Good Grips Y Peeler and Zester Set
Getting clean lemon zest without the bitter white pith underneath is way easier with a proper microplane-style zester.
The citrus zest in this recipe adds a layer of flavor that you just can’t get from juice alone. This set is compact, easy to clean, and works beautifully.
3. Mezzetta Whole Roasted Garlic
When you want to take the garlic flavor up a notch without extra prep time, roasted garlic paste is a fantastic shortcut.
Stir a tablespoon into the sauce for a deeper, more mellow garlic flavor that pairs beautifully with the lemon and squash.
4. Bragg Organic Extra Virgin Olive Oil
A good olive oil is the backbone of this dish. Bragg’s is cold-pressed, has a clean, grassy flavor, and is certified organic.
Using a quality oil makes a noticeable difference when it’s doing the heavy lifting as both a cooking fat and a flavor component.
This dish also pairs well with a light pasta side. My Chicken Piccata Pasta uses a similar lemon-forward flavor profile that would make a great accompaniment.
Step-by-Step Instructions: How to Make Chicken and Summer Squash
1. Prep Your Ingredients
- Pat the chicken breast pieces completely dry with paper towels. This is important because surface moisture prevents browning.
- Cut the chicken into roughly 1-inch bite-sized chunks. Try to keep the pieces as uniform as possible so they cook evenly.
- Slice the yellow squash and zucchini into half-moon shapes, about 1/2 inch thick. Thinner pieces may turn mushy; thicker pieces will stay crisp-tender.
- Mince the garlic cloves finely. You want small, even pieces so the garlic cooks consistently without burning.
- Dice the onion into small, even pieces.
- Zest the lemon first, then juice it. Set both aside.
- Measure out all spices and have them ready before you start cooking.
2. Season the Chicken
- Place the chicken pieces into a medium bowl.
- Add 1 teaspoon of Italian seasoning, 1 teaspoon of garlic powder, 1/2 teaspoon of onion powder, 1/2 teaspoon of smoked paprika, and a generous pinch of salt and black pepper.
- Add 1 teaspoon of lemon zest to the bowl.
- Toss everything together until the chicken is well coated in the spice mixture. Let it sit for 5 minutes while you heat the skillet.
3. Sear the Chicken
- Heat 1 tablespoon of olive oil in a large 12-inch skillet over medium-high heat. Wait until the oil is shimmering before adding the chicken.
- Add the chicken pieces to the skillet in a single layer. Do not crowd the pan. If your skillet is not large enough, cook in two batches.
- Let the chicken cook undisturbed for 3 to 4 minutes until it develops a golden-brown crust on the bottom.
- Flip each piece and cook for another 2 to 3 minutes until the chicken is cooked through and reaches an internal temperature of 165°F.
- Transfer the cooked chicken to a clean plate and tent loosely with foil to keep warm. Leave the drippings in the pan.
4. Sauté the Aromatics
- Reduce the heat to medium. Add the remaining 1 tablespoon of olive oil and 1 tablespoon of butter to the same skillet.
- Add the diced onion and cook, stirring occasionally, for 2 to 3 minutes until it turns soft and translucent.
- Add the minced garlic and stir constantly for about 30 seconds to 1 minute. The garlic should be fragrant but not browned. Browning garlic makes it bitter, so watch closely.
5. Cook the Summer Squash
- Increase the heat back to medium-high.
- Add the sliced yellow squash and zucchini to the skillet in a single layer.
- Season with the remaining 1/2 teaspoon of Italian seasoning, a pinch of salt, and black pepper.
- Cook the squash for 3 to 5 minutes, stirring occasionally, until it is crisp-tender and lightly golden on the edges. You want the squash to have a little texture, not be completely soft.
- Avoid stirring too frequently. Letting the squash sit on the hot pan gives it those nicely browned edges.
6. Build the Lemon-Garlic Sauce and Combine
- Add the 3 tablespoons of fresh lemon juice to the skillet and stir to scrape up any browned bits from the bottom of the pan. Those browned bits add a lot of flavor to the sauce.
- Return the cooked chicken (along with any accumulated juices from the plate) back to the skillet.
- Toss everything together gently so the chicken and squash are coated in the lemony pan sauce.
- Taste and adjust seasoning. Add more salt, pepper, or lemon juice as needed.
- Cook for another 1 to 2 minutes just to heat everything through and let the flavors come together.
7. Garnish and Serve
- Remove the skillet from heat.
- Sprinkle the chopped fresh parsley over the top.
- If using, scatter the grated Parmesan cheese over the dish. The residual heat will gently melt it into the sauce.
- Serve immediately with lemon wedges on the side so people can add extra brightness to their own portion.
Tips for The Best Chicken and Summer Squash
A few small adjustments can make a big difference in how this dish turns out.
The biggest mistake most people make is overcrowding the pan, which causes the chicken and squash to steam instead of sear.
Give everything enough room, and you’ll get that golden color and caramelized flavor that makes this dish stand out.
- Pat the chicken dry. Moisture on the surface of the chicken prevents browning. Always dry it with paper towels before seasoning.
- Don’t crowd the pan. Cook chicken in batches if needed. A single layer is essential for a proper sear.
- Cut squash evenly. Uniform pieces ensure everything finishes cooking at the same time.
- Use fresh lemon juice. Bottled lemon juice has a dull, slightly bitter flavor. Fresh juice is brighter and more vibrant.
- Don’t overcook the squash. It goes from perfectly tender to mushy quickly. Pull it off the heat while it still has a little bite.
- Add Parmesan off the heat. Stirring cheese into a very hot pan can cause it to clump. Remove from heat first, then add.
- Save the chicken drippings. Don’t wipe out the pan between cooking the chicken and the vegetables. Those golden bits at the bottom add incredible depth.

Variations of Chicken and Summer Squash
Once you’ve made the base recipe, it’s easy to spin it in a bunch of different directions depending on what’s in your fridge.
This dish is very forgiving, so don’t be afraid to experiment with different vegetables, proteins, or flavor profiles.
- Add cherry tomatoes. Toss in a cup of halved cherry tomatoes with the squash. They burst and create a light, saucy base.
- Use chicken thighs. Boneless, skinless thighs are juicier and more forgiving than breasts. Adjust cook time slightly.
- Make it creamy. Stir in 2 tablespoons of cream cheese or a splash of heavy cream with the lemon juice for a richer sauce.
- Add a Mexican twist. Swap Italian seasoning for chili powder, cumin, and smoked paprika, and top with shredded Monterey Jack cheese.
- Go Mediterranean. Add kalamata olives, sun-dried tomatoes, and a crumble of feta cheese at the end.
- Try a sheet pan version. Toss everything in olive oil and seasoning and roast at 425°F for 20 to 25 minutes.
- Add corn. Fresh or frozen corn kernels add sweetness and a little texture that works beautifully with the squash.
- Make it spicy. Add a pinch of red pepper flakes with the garlic for a little heat.
Storage and Reheating
This dish stores well and tastes great the next day, making it a solid choice for meal prep.
Keep in mind that the squash will soften slightly after refrigerating, but the flavor gets even better as everything melds overnight.
- Refrigerator: Store leftovers in an airtight container for up to 4 days.
- Freezer: Freeze in a sealed container for up to 2 months. Thaw overnight in the fridge before reheating.
- Reheat on the stovetop: Warm in a skillet over medium heat for 3 to 5 minutes, adding a splash of water or broth to loosen the sauce.
- Reheat in the microwave: Microwave in 60-second increments, stirring between each, until heated through.
- Do not reheat on high heat. Too much heat will make the squash completely fall apart and dry out the chicken.
- Meal prep tip: Store the chicken and squash separately from any grain or pasta to keep the textures fresh.
Another great weeknight meal to add to your rotation is this Chicken and White Bean Stew, which stores and reheats just as beautifully.

FAQs About Chicken and Summer Squash
1. Can I use chicken thighs instead of chicken breast?
Yes, absolutely. Boneless, skinless chicken thighs work great in this recipe and are actually more forgiving than breasts because they’re harder to overcook.
They have a richer flavor and stay juicy even if they spend a couple extra minutes in the pan.
Just adjust cook time to about 5 to 6 minutes per side depending on thickness.
2. How do I keep the squash from getting mushy?
The key is not overcooking it. Summer squash cooks very quickly, so keep the heat at medium-high and only cook it for 3 to 5 minutes.
Stir occasionally but not constantly, and pull it off the heat while it still has a slight bite.
Cutting the pieces a little thicker, about 1/2 inch, also helps them hold their shape.
3. Can I make this recipe ahead of time?
You can prep all the ingredients ahead of time, including seasoning the chicken and slicing the squash, then store everything separately in the fridge for up to 24 hours.
The full dish can also be cooked ahead and refrigerated for up to 4 days.
Just be aware the squash will soften slightly after storage, but the flavor will still be excellent.
4. What can I substitute for fresh lemon juice?
Fresh lemon juice is strongly preferred here because it gives the sauce a bright, clean flavor.
If you don’t have a lemon on hand, you can use 1 to 2 tablespoons of white wine vinegar for acidity, though the flavor will be slightly different.
A small splash of dry white wine also works well as a substitute and adds great depth to the sauce.
5. Can I add other vegetables to this recipe?
Definitely. This recipe is very flexible. Cherry tomatoes, bell peppers, fresh corn kernels, baby spinach, and asparagus all work well.
Just keep in mind that different vegetables have different cook times.
Add heartier vegetables like bell peppers earlier in the process, and quick-cooking ones like spinach right at the end so they just wilt.

Notes
- Pat the chicken completely dry before seasoning — surface moisture prevents browning and you’ll lose that golden crust.
- Do not crowd the pan. If your skillet is smaller than 12 inches, sear the chicken in two batches for even browning.
- Cut the squash pieces uniformly (about 1/2 inch thick) so everything finishes cooking at the same time.
- Use fresh lemon juice for the best flavor — bottled lemon juice produces a flatter, slightly bitter result.
- The squash cooks fast. Pull it from the heat while it still has a slight bite; residual heat will finish it off.
- Chicken thighs can be substituted for chicken breast — they are juicier and more forgiving. Adjust cook time to 5 to 6 minutes per side.
- To make it creamy, stir in 2 tablespoons of cream cheese or a splash of heavy cream along with the lemon juice.
- Store leftovers in an airtight container in the refrigerator for up to 4 days or freeze for up to 2 months.
- Reheat in a skillet over medium heat with a splash of water or broth to loosen the sauce; avoid high heat to keep the squash from turning mushy.
- Add cherry tomatoes, fresh corn kernels, or baby spinach for extra color and nutrition.
