Ingredients for Your Flavorful Skillet

Crafting this quick and delicious skillet dinner starts with fresh, high-quality ingredients. Here’s a breakdown of what you’ll need to create this amazing dish, along with some tips:

Ingredients in Mexican chicken and squash skillet
  • Mazola® Corn Oil: An excellent all-purpose cooking oil. It has a neutral flavor that won’t overpower your dish, and its high smoke point makes it perfect for sautéing the onions, garlic, and chicken. Plus, it’s heart-healthy*!
  • Aromatics (Yellow Onion & Garlic): The foundation of flavor for this dish. Diced yellow onion and minced garlic provide a aromatic base that adds depth and richness.
  • Boneless, Skinless Chicken Breast: Sliced into bite-sized chunks, the chicken cooks quickly and evenly. You can also use chicken thighs if you prefer a richer flavor and slightly longer cooking time.
  • Mexican-Inspired Spices: A powerful trio of Chili Powder, Ground Cumin, and Smoked Paprika creates a warm, earthy, and slightly smoky flavor profile that defines the dish’s Southwestern character. Don’t forget Kosher Salt to enhance all the flavors.
  • Summer Squash Duo (Yellow Squash & Zucchini): These tender summer vegetables absorb the spices beautifully. I love using both for variety in color and subtle texture differences, but feel free to use all yellow squash or all zucchini, depending on what you have on hand.
  • Fresh Corn Kernels: Nothing beats the sweetness of fresh corn sliced directly off the cob during summer. If fresh isn’t available, about 1 cup of frozen or canned (drained) corn kernels will work just as well, offering that delightful pop of sweetness.
  • Roma Tomatoes: Quartered, these tomatoes break down slightly during cooking, releasing their juices to create a light, fresh, and flavorful sauce that coats all the ingredients.
  • Shredded Cheese: The secret to that glorious, gooey top layer! Cheddar cheese is a classic choice, but Monterey Jack, Colby Jack, or even mozzarella would melt beautifully and add a creamy, savory finish.
  • Fresh Garnishes: A sprinkle of Chopped Cilantro and a squeeze of fresh Lime Juice at the end brighten the entire dish, adding a burst of freshness and acidity that cuts through the richness of the cheese and spices.

Choosing the Best Summer Produce

For the freshest and most flavorful skillet, selecting peak-season produce is key:

  • Squash: Look for firm, brightly colored yellow squash and zucchini free of blemishes. They should feel heavy for their size. Smaller to medium-sized squash tend to be more tender with fewer seeds.
  • Corn: Choose corn cobs with bright green husks that are tightly wrapped. The silk should be damp and golden brown. Avoid cobs with dry or black silk, or those with holes in the husks.
  • Tomatoes: Ripe Roma tomatoes should be deep red, smooth-skinned, and firm but yield slightly to gentle pressure. They should also smell earthy and sweet at the stem end.

How to Make This Easy Chicken and Summer Squash Skillet

This incredible summer squash recipe comes together effortlessly, all in one skillet! Follow these simple steps for a delicious meal:

Cooking chicken and squash in a skillet with a wooden spoon.
  1. Sauté Aromatics: Begin by heating the Mazola® Corn Oil in a large, sturdy skillet or pot over medium-high heat. Add the diced yellow onion and minced garlic. Sauté for about 3 minutes, stirring occasionally, until the onions become translucent and fragrant. This step builds the flavor base for your entire dish.
  2. Cook the Chicken: Add the bite-sized chicken chunks to the skillet along with the chili powder, ground cumin, smoked paprika, and kosher salt. Stir everything well to ensure the chicken is evenly coated with the spices. Cook for 6-8 minutes, stirring periodically, until the chicken is fully cooked through and no longer pink.
  3. Introduce the Vegetables: Now it’s time to add the fresh summer vegetables! Stir in the quartered yellow squash, zucchini, fresh corn kernels, and quartered Roma tomatoes. Continue to cook for another 8-10 minutes, stirring occasionally. You want the squash to become fork-tender but still retain a slight bite, and the tomatoes to soften and release their flavorful juices, creating a light sauce.
  4. Melt the Cheese: Once the vegetables are tender, remove the skillet from the heat. Generously sprinkle the shredded cheese evenly over the top of the chicken and vegetables. Cover the skillet with a lid and let it sit for 3-5 minutes. The residual heat will perfectly melt the cheese into a wonderfully gooey, irresistible layer.
  5. Garnish and Serve: Uncover the skillet, and for a burst of freshness, garnish with plenty of chopped cilantro and a squeeze of fresh lime juice. Serve immediately and enjoy the delightful flavors of summer!

Tips for Success & Recipe Variations

Elevate your skillet game with these handy tips and ideas for customization:

  • Don’t Overcrowd the Pan: Ensure your skillet is large enough to hold all ingredients in a single layer or without excessive piling. Overcrowding can steam the ingredients instead of sautéing them, leading to less flavorful results.
  • Adjust Spice Levels: If you love heat, consider adding a pinch of cayenne pepper or a diced jalapeño along with the other spices. For a milder dish, you can slightly reduce the chili powder.
  • Add a Splash of Broth: If you find the skillet a little dry or want more sauce, add about 1/4 to 1/2 cup of chicken broth or vegetable broth when you add the vegetables.
  • Vegetable Swaps: This recipe is incredibly adaptable! Feel free to add or substitute other quick-cooking vegetables like diced bell peppers (any color), chopped onions, or even spinach (add towards the end, just before the cheese).
  • Bean Boost: Stir in a can of drained and rinsed black beans or pinto beans with the vegetables for added protein and fiber, giving it an even heartier Southwestern flair.
  • Different Proteins: While chicken breast is fantastic, you could also use boneless, skinless chicken thighs (they might need a couple of extra minutes to cook) or even cooked shrimp (add at the very end to prevent overcooking). For a vegetarian version, omit the chicken and add extra beans or plant-based protein.
  • Cheese Choices: Experiment with different cheeses! A blend of Mexican cheeses, pepper jack for a little kick, or even provolone can offer unique flavors and textures.

Serving Suggestions for Your Skillet

This dish is wonderfully fulfilling on its own, but it also pairs beautifully with a variety of sides to complete your meal. Here are some fantastic options:

A southwest chicken and squash skillet topped with cheese and cilantro.
  • Classic Sides: Serve with warm Mexican Rice or Cilantro Lime Cauliflower Rice for a lighter, low-carb option.
  • Beans: A side of Canned Black Beans or Easy Refried Beans adds extra protein and makes it a more robust meal.
  • Tortillas or Tortilla Chips: Warm flour or corn tortillas are perfect for making mini-tacos or wraps. Crunchy tortilla chips are great for scooping up all the flavorful chicken and veggies.
  • Fresh Toppings: Offer a variety of fresh toppings like diced avocado or guacamole, a dollop of sour cream or Greek yogurt, extra chopped cilantro, or a dash of your favorite hot sauce for those who like a little extra kick.
  • Simple Salad: A crisp green salad with a light vinaigrette can provide a refreshing contrast to the hearty skillet.

Making Ahead & Storing Leftovers

This skillet is fantastic for meal prep or enjoying as leftovers!

  • Make Ahead: You can chop all the vegetables and chicken in advance and store them separately in airtight containers in the refrigerator for up to 2 days. This will cut down your cooking time even further on the day you plan to cook.
  • Storage: Leftovers can be stored in an airtight container in the refrigerator for 3-4 days.
  • Reheating: Reheat gently in a skillet over medium-low heat or in the microwave until warmed through. You may want to add a splash of water or broth if it seems a bit dry.
  • Freezing: This dish freezes reasonably well, though the squash may become slightly softer upon thawing. Store in a freezer-safe container for up to 2-3 months. Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions (FAQs)

Here are answers to some common questions about this delicious chicken and summer squash skillet:

  • Can I use frozen vegetables? Yes, absolutely! If using frozen corn, you can add it directly to the skillet with the other vegetables. For frozen squash, it’s best to thaw it first and pat it dry to remove excess moisture before adding to prevent the dish from becoming watery.
  • Can I use ground chicken or turkey instead of chicken breast? Yes, ground chicken or turkey would work wonderfully. Cook the ground meat first, breaking it up with a spoon, until it’s browned and cooked through, then proceed with adding the spices and vegetables.
  • Is this recipe spicy? The recipe as written is mildly spiced, offering a warm and savory flavor without significant heat. If you prefer more spice, you can increase the amount of chili powder or add a pinch of cayenne pepper or red pepper flakes.
  • How can I make this vegetarian or vegan? To make it vegetarian, simply omit the chicken and add extra beans (like black beans or pinto beans) or plant-based protein alternatives such as tofu or tempeh chunks. For a vegan version, also omit the cheese or use a dairy-free shredded cheese alternative.
  • Can I add other herbs? While cilantro is traditional for Mexican-inspired dishes, you could also experiment with fresh parsley or even a tiny bit of oregano. Always add fresh herbs at the very end of cooking to preserve their vibrant flavor.
