Ingredients You'll Need (and Why)
Chicken Breasts: Cutting the chicken into uniform 1-inch cubes ensures every piece sears quickly and stays juicy without drying out.
Cherry Tomatoes: High heat causes the tomato skins to blister and burst, releasing sweet juices that mix with melted butter to create a rich pan sauce.
Unsalted Butter: Using unsalted butter lets you control the dish's final saltiness, while browning part of it adds a nutty richness to the garlic.
Olive Oil: Combining oil with butter raises the smoke point, preventing the butter solids from burning during the initial high-heat chicken sear.
Zucchini: Slicing zucchini into thick half-moons gives them enough structure to brown nicely on the outside without turning mushy.
How to Make It
Searing the Chicken
Starting with dry chicken cubes is the secret to getting a deep, flavorful brown crust. If moisture remains on the surface, the chicken steams instead of browning. Cook in a hot pan with combined oil and butter, leaving space between pieces so they sear quickly while locking in moisture.
Building the Garlic Butter Sauce
Dropping the heat before adding garlic protects it from scorching, which would turn the sauce bitter. A short 30-second sauté blooms the garlic's aromatic oils directly into the warm melted butter, laying a sweet, savory foundation for the vegetables.
Sautéing Vegetables & Finishing
Adding the zucchini and cherry tomatoes together allows them to soften simultaneously. As the tomatoes pop open, their natural acidity combines with the garlic butter to form an effortless pan sauce. Folding the chicken back in coats every piece in sauce without overcooking the meat.
Success Tips
- Pat the raw chicken dry with paper towels before seasoning; surface moisture causes steaming rather than golden searing.
- Cut the zucchini into evenly thick half-moons (about 1/2-inch thick) so they sear nicely on the edges without turning soft inside.
- Turn off the heat right when the cherry tomatoes burst so their juice emulsifies into the garlic butter without completely evaporating.
Variations
- Swap chicken breasts for skinless chicken thighs for extra juicy flavor.
- Add 1/2 cup of heavy cream at the end for a creamy garlic butter tomato sauce.
- Substitute zucchini with yellow summer squash or thin asparagus spears.
Storage & Make-Ahead
Fridge: Store leftovers in an airtight container in the refrigerator for up to 3-4 days. Reheat gently in a skillet over low heat with a splash of water or butter.
FAQ
How do I keep zucchini from getting soggy?
Cut the zucchini into thicker 1/2-inch slices and sauté over medium-high heat for just 4-5 minutes. Avoid salting the zucchini directly before cooking, as salt draws out excess liquid.
Can I use chicken thighs instead of breasts?
Yes! Boneless, skinless chicken thighs work fantastically and stay very tender. Cook them using the exact same timing as the breasts.
What can I serve with this garlic butter chicken?
This meal is complete on its own for a low-carb option, but it also pairs wonderfully over pasta, rice, quinoa, or with warm crusty bread to soak up the garlic butter sauce.
