It can be a high protein meal when served with a smart side, and it is good for weight loss because it is low calorie and full of filling fiber from the squash and tomato.

HOW TO MAKE Chicken and Summer Squash
This skillet method keeps the chicken juicy and lets the summer vegetables soften without losing texture. The tomato adds a touch of brightness and natural juice so you do not need extra sauce.
EQUIPMENT NEEDED
- Large nonstick skillet with lid
- Tongs or spatula
- Instant-read thermometer (recommended)
- Cutting board and sharp knife
- Plate and aluminum foil to keep chicken warm
Ingredients You’ll Need :
4 skinless, boneless chicken breasts, 1/2 teaspoon salt, divided, 1/4 teaspoon ground black pepper, divided, 1 tablespoon butter, 1 tablespoon vegetable oil, 12 ounces yellow squash, sliced, 12 ounces zucchini, sliced, 1 medium tomato, peeled, seeded, and chopped
STEP-BY-STEP INSTRUCTIONS :
Season chicken with 1/4 teaspoon salt and 1/8 teaspoon black pepper. Melt butter with oil in a large nonstick skillet over medium-high heat. Add chicken. Cook until lightly browned, about 2 minutes per side. Transfer to a large plate. Cover with aluminum foil to keep warm. Discard drippings from the skillet. Add yellow squash, zucchini, and tomato to the same skillet over medium-high heat. Season with remaining 1/4 teaspoon salt and remaining 1/8 teaspoon black pepper. Cook and stir until squash is slightly softened, about 3 minutes. Reduce heat, return chicken to the skillet, and cover partially. Cook until squash is soft and chicken is no longer pink in centers, the juices run clear, but still juicy, about 5 minutes more. An instant-read thermometer inserted into chicken breast centers should read at least 165 degrees F (74 degrees C). Transfer chicken to a serving platter. Cover with aluminum foil to keep warm. Increase heat to high. Continue cooking vegetable mixture, stirring often, until most of the liquid has evaporated, about 2 minutes. Serve vegetables around chicken.

HOW TO SERVE Chicken and Summer Squash
Serve the chicken sliced with the sauteed squash and tomato spooned around it. Portion control is easy: one medium chicken breast and about one cup of vegetables makes a balanced plate. For a high protein meal, pair with a small side of quinoa or a cup of cottage cheese. For low calorie and low carb serving ideas, skip grains and add a fresh green salad or a cup of steamed broccoli.
Keep servings sensible: aim for 3 to 4 ounces of cooked chicken per person if you are counting calories, or one whole breast for a more generous portion if you are very active. This recipe is a great meal prep choice because you can divide the cooked chicken and vegetables into containers for 3 to 4 meals.
STORAGE & FREEZING : Chicken and Summer Squash
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over low heat to keep chicken moist. For longer storage, you can freeze cooked chicken and vegetables in freezer-safe containers for up to 2 months. Thaw in the fridge overnight before reheating. If you plan to freeze, slightly undercook the vegetables so they do not get mushy after thawing and reheating.
SERVING SUGGESTIONS
- Healthy side: Serve with a big green salad dressed with lemon and olive oil for a heart healthy pairing.
- Low calorie option: Replace grains with a side of roasted cauliflower rice.
- Balanced meal: Add a small serving of brown rice or farro for fiber and extra energy if you need more carbs after a workout.
- Flavor boost: Sprinkle fresh basil or parsley on top before serving for bright flavor.
- If you want a saucier pairing, check out a contrasting slow-cooked dish like dump-and-go crockpot teriyaki chicken for a different meal plan idea that also works well with meal prep cycles.
VARIATIONS
- Healthier version: Use olive oil instead of vegetable oil and reduce butter to a half teaspoon. Add extra zucchini and bell peppers to up the fiber and volume while keeping calories low. This keeps the dish heart healthy and lighter.
- High-protein or low-carb version: Serve the chicken with a side of steamed green beans or a spinach salad and skip any rice or bread. You can also increase chicken to 6 breasts to raise protein per serving for a true high protein meal.
- Air fryer or oven-baked version: For a crisp finish, season the chicken and air fry at 375°F (190°C) for 10–12 minutes, flipping halfway, until the internal temperature reaches 165°F. Toss sliced squash and tomato with a little oil, roast at 425°F (220°C) for 12–15 minutes, then plate with the cooked chicken. For oven-baked, place chicken and vegetables in a single baking dish, cover loosely, and bake at 375°F (190°C) for 20–25 minutes until chicken reaches safe internal temperature. These versions are great when you want less stovetop time or if you prefer a roast flavor.
