Step 1: Preheat the Oven : Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or foil for easy cleanup.
Step 2: Prepare the Zucchini : Place the zucchini slices on the prepared baking sheet. Drizzle with olive oil and sprinkle salt, pepper, and oregano (or Italian seasoning). Toss to coat evenly and spread out in a single layer. Roast in the preheated oven for 15–20 minutes, flipping halfway through, until tender and lightly golden.
Step 3: Season the Chicken : Pat chicken thighs dry with paper towels. Season both sides with salt, pepper, paprika, and garlic powder.
Step 4: Sear the Chicken : Heat olive oil in a large skillet (cast-iron preferred) over medium-high heat. Add chicken thighs skin-side down (if using skin-on). Sear for 5–7 minutes per side until golden brown and cooked through (internal temp 165°F / 74°C). Remove the chicken and set aside on a plate.
Step 5: Make the Garlic Butter Sauce : In the same skillet, reduce heat to medium. Add butter and let it melt, scraping up any brown bits from the pan. Add minced garlic and red chili flakes; sauté for 30–40 seconds until fragrant (don’t let it burn). Stir in lemon juice for brightness.
Step 6: Combine and Glaze : Return the chicken to the skillet and spoon the garlic butter sauce over it. Let simmer for 2–3 minutes until everything is coated and glossy. Sprinkle with fresh parsley.
Step 7: Serve : Serve the garlic butter chicken hot, topped with pan sauce, alongside roasted zucchini. Add a sprinkle of Parmesan and an extra squeeze of lemon juice if desired.
