Ingredients

  

• 1.25–1.5 pounds boneless, skinless chicken breasts or thighs, cut into bite-size pieces
• 2 medium zucchinis, halved lengthwise and sliced into half-moons
• 1 small yellow onion, thinly sliced
• 3 cloves garlic, minced
• 1 red bell pepper, sliced (optional, for color and sweetness)
• 2 tablespoons olive oil (divided)
• 1 teaspoon kosher salt (divided), plus more to taste
• 1/2 teaspoon black pepper
• 1 teaspoon Italian seasoning or dried oregano and basil
• 1/2 teaspoon smoked paprika (optional, for depth)
• 1/4 teaspoon red pepper flakes (optional, for heat)
• 1 tablespoon tomato paste (optional) or 1/2 cup cherry tomatoes, halved
• 1/4 cup low-sodium chicken broth or water (as needed)
• Zest and juice of 1/2 lemon
• 2 tablespoons chopped fresh parsley or basil
• Grated Parmesan or crumbled feta, for serving (optional)

Instructions

 

• Prep the produce and chicken: Cut the chicken into 1-inch pieces. Slice the zucchini, onion, and bell pepper. Mince the garlic. Pat the chicken dry and season with 1/2 teaspoon salt, black pepper, and half the Italian seasoning.
• Heat the skillet: Warm 1 tablespoon olive oil in a large skillet over medium-high heat. When the oil shimmers, add the chicken in a single layer. Cook, undisturbed, for 2–3 minutes to sear, then stir and cook another 3–4 minutes until just cooked through. Transfer to a plate.
• Sauté the veggies: Lower heat slightly to medium. Add the remaining 1 tablespoon olive oil. Add onion and bell pepper with a pinch of salt and cook 3 minutes until softened. Stir in zucchini and cook 3–5 minutes until tender-crisp.
• Add flavor boosters: Stir in garlic, remaining Italian seasoning, smoked paprika, and red pepper flakes. Cook 30–60 seconds until fragrant. If using tomato paste, add it now and cook another minute to caramelize lightly. If using cherry tomatoes, stir them in to soften.
• Bring it together: Return chicken and any juices to the skillet. Add a splash of broth to loosen browned bits and create a light sauce. Simmer 1–2 minutes, stirring, until everything is hot and coated.
• Finish and taste: Remove from heat. Stir in lemon zest and juice, and half the herbs. Taste and adjust with more salt, pepper, or lemon as needed.
• Serve: Top with remaining herbs and a sprinkle of Parmesan or feta if you like. Serve as-is, over rice or cauliflower rice, or with warm crusty bread.

Storage Instructions

• Refrigerator: Cool completely, then store in an airtight container for up to 4 days.
• Freezer: Freeze in portions for up to 2 months. Zucchini may soften more after thawing, but flavor stays solid.
• Reheat: Warm gently in a skillet over medium heat with a splash of broth or water, or microwave in 45-second bursts, stirring between intervals.
• Meal prep tip: Keep lemon and cheese separate and add after reheating to keep flavors bright.

Benefits of This Recipe

• High in protein: Chicken provides a substantial protein boost to support muscle repair and satiety.
• Veggie-forward: Zucchini, onion, and pepper deliver fiber, potassium, vitamin C, and antioxidants.
• Lower-carb option: Naturally lower in carbs, especially if served without grains or with cauliflower rice.
• Balanced flavors: Lemon, herbs, and a touch of heat keep the dish bright and satisfying without heavy sauces.
• Budget-friendly and practical: Uses common ingredients and stretches well with rice, quinoa, or beans.

Common Mistakes to Avoid

• Overcrowding the pan: If the chicken is packed too tightly, it steams instead of sears. Cook in batches if needed.
• Overcooking the zucchini: It turns mushy fast.

  Aim for tender-crisp and pull it off the heat promptly.

• Skipping the seasoning: Salt in layers—some on the chicken, some on the veggies, and a final taste at the end.
• Forgetting acidity: The lemon brings the dish to life. Don’t skip it.
• Using high heat throughout: Sear chicken hot, but drop the heat slightly for veggies to avoid burning garlic or spices.

Variations You Can Try

• Garlic Parmesan: Add 1–2 extra cloves of garlic and finish with a generous handful of grated Parmesan.
• Spicy Cajun: Swap Italian seasoning for Cajun seasoning and add an extra pinch of red pepper flakes.
• Mediterranean: Add olives, cherry tomatoes, and finish with crumbled feta and fresh oregano.
• Creamy Tuscan: Stir in 1/4 cup light cream or coconut milk and a handful of spinach at the end.
• Extra protein: Toss in a can of drained chickpeas during the final simmer for more fiber and protein.
• Grain bowl: Serve over quinoa or farro and drizzle with a quick lemon-herb vinaigrette.
• Low-carb swap: Replace bell pepper with mushrooms and serve over cauliflower rice.
