Easy Baked Thin Sliced Chicken Breasts (No Brine, Stays Juicy)

How to thinly slice chicken breast

Slicing the chicken breasts into thinner cutlets helps them absorb the marinade better and faster, which is what makes baked thinly sliced chicken breast so much quicker and juicier than cooking a whole, thick breast.

I use thin-sliced chicken breasts in many of my recipes like sun dried tomato pesto chicken and baked panko crusted thin chicken breasts.

• Place the chicken breasts on a cutting board.
• Using a sharp knife, slice the breasts horizontally to make them about 1/2 to 3/4 inch thick. If the thickness is not uniform, lightly pound the thicker part with a meat mallet.
• Keeping this thickness consistent matters because the chicken cooks covered — so even thickness means even cooking throughout.

The marinade: how to tenderize chicken without brining

(You can find the exact measurements and instructions in the printable recipe card at the end of this page. Here are step-by-step instructions with pictures to help you easily understand the recipe.)

Brining is the go-to tenderizing method for most baked chicken breast recipes — but it takes hours, and an extra bowl of saltwater in your fridge.

This recipe skips the brine entirely and uses a quick marinade instead, the same way a yogurt marinade tenderizes tandoori chicken tikka.

This marinade — really a wet rub — sits halfway between a dry spice rub and a true marinade. A plain dry rub has no acid to tenderize the meat, so this version adds lemon juice to a simple spice base:

• garlic powder
• onion powder
• chili powder
• paprika
• dried rosemary
• salt

The lemon juice tenderizes while the oil — just enough, not a heavy pour — locks in moisture so the chicken doesn’t dry out in the oven.

1. Combine the spices in a small bowl.
2. Add lemon juice.
3. Add olive oil.
4. Whisk until smooth.
5. Blot the thin sliced chicken breasts dry with kitchen towels, then mix in the marinade.
6. Pierce the chicken cutlets with a fork so the marinade absorbs fully.

How long to marinate chicken for baking?

Marinate the thin slices of chicken breast for at least 15 minutes. Marinating overnight in the fridge gives the best results.

Take the chicken cutlets out of the fridge 20 minutes before cooking so it reaches room temperature. There’s no need to refrigerate at all if you’re only marinating for 15 minutes.

Preheat the oven to 450°F/ 230°C — the ideal temperature for thin chicken cutlets to stay juicy.

Place the marinated chicken breasts in a deep baking tray lined with parchment paper, and seal tightly with aluminum foil.

Bake for 10 minutes. If your slices are under 1/2 inch thick, reduce the time by a couple of minutes.

Then, for color: Remove the foil, switch the oven to broil, and broil for 2–3 minutes until the tops turn golden. Watch closely, since thin chicken can go from golden to overdone quickly under a broiler.

The one step that guarantees it’s done right: Insert an instant-read thermometer into the thickest piece. It should read 165°F (74°C). If it’s not quite there, slide it back in for another minute and check again. This single check is the difference between perfectly juicy chicken and the dry or undercooked results some people run into with time-only methods.

Let it rest for 5 minutes once out of the oven. The pan juices left behind are a bonus — drizzle them over the chicken or use them in a salad dressing.

Slice the chicken (against the grain) and serve, garnished with fresh parsley.

There! You’ve learned the secret to cooking the best thin sliced chicken breasts in the oven with very little effort and time.

How to cook thin sliced chicken breast without drying it out?

The marinade and short bake time do most of the work, but a few details make the difference between juicy and dry:

• Bring the chicken to room temperature before baking, for more even cooking.
• Blot the chicken dry before marinating, so the marinade can actually adhere and absorb.
• Space the chicken pieces at least an inch apart on the pan — crowding leads to uneven cooking.
• Check for 165°F with a thermometer rather than relying on time alone, especially if your slices vary in thickness.
• Remove the foil once it’s out of the oven — otherwise condensing steam makes the chicken soggy instead of juicy.
• Let it rest for 5–10 minutes — this keeps the juices in the meat instead of spilling out the moment you cut into it.
• Slice against the grain — This cuts through the long muscle fibers, giving you softer, more tender meat.

Is this baked chicken breast recipe good for diabetic patients?

As someone certified in nutrition and wellness, this is a question I get asked often — and this recipe happens to be a genuinely solid fit for blood-sugar-conscious eating, for a few concrete reasons:

• Almost no carbs or sugar: about 1.5g of carbohydrate and 0.2g of sugar per serving, so it has minimal direct impact on blood glucose.
• Very high protein: about 48g per serving, which supports satiety and helps slow the blood sugar response when this chicken is paired with any carbohydrate side.
• Lean preparation: no breading, no sugary glaze, and only a light coating of oil, so you’re not adding unnecessary fat or hidden sugar.

For a fuller diabetic-friendly plate, pair it with a non-starchy vegetable and a modest portion of a high-fiber carbohydrate (like the quinoa pumpkin salad) rather than a refined-carb side.

This is general nutrition information, not individual medical advice — if you’re managing diabetes, it’s always worth checking with your doctor or a registered dietitian about how a specific meal fits your personal plan.

Storage, reheating, and freezing

Storage: Keep leftover chicken in an airtight container in the refrigerator for up to 3–4 days (with the pan juices)

Reheating: Let the chicken sit out of the fridge for 10–15 minutes, then reheat (with the juices) in the oven or microwave in a loosely covered dish. A short blast at high heat keeps it from drying out, the same way it cooked the first time.

Freezing: Once fully cooled, this chicken freezes well in an airtight container or freezer bag for up to 3 months. Thaw overnight in the refrigerator before reheating.

Meal prep tip: This is one of the easiest proteins to batch-cook for the week — slice or cube it once cooled, and use it across salads, wraps, grain bowls, or soups all week long.

What to pair with baked thin sliced chicken breasts

These chicken breasts taste amazing with Italian pasta salad with balsamic dressing, beetroot walnut feta salad with roasted garlic dressing, or beet orange salad.

Pair them with sides like roasted potatoes and broccoli or easy cheesy Italian potato croquettes.

Want to make the healthiest dinner? Try superfood salads like quinoa pumpkin salad or balsamic quinoa salad. — both pair beautifully with this chicken.

Craving creamy pasta on the side? Go for guilt-free mushroom zucchini pasta or mixed veggie pasta with garlic sauce.
