Lemon rosemary chicken breast is one of those baked chicken recipes that looks far more impressive than the effort it takes. Boneless chicken breasts go into a zip-lock bag with a garlic and lemon marinade, sit in the fridge for an hour, then bake in a single casserole dish at 400°F for 30 minutes. The result is deeply flavored, juicy chicken with a golden top, No searing, no fuss, no dried-out breast.


My Go-To Weeknight Chicken
I have been making baked chicken breast on weeknights for years now and this lemon rosemary version has been in the rotation longer than almost any other recipe on this blog. It is the kind of dish I reach for when I want something that feels real and satisfying but I do not want to spend more than 10 minutes in the kitchen getting it ready.
The marinade is the reason this recipe works. Fresh lemon juice, minced garlic, smoked paprika, and olive oil do more for a chicken breast in one hour than any dry rub can. I have tested this with as little as 30 minutes of marinating time and it is noticeably less flavorful. An hour is the sweet spot. The acid from the lemon also begins to tenderize the meat, which is part of why this chicken stays so juicy in the oven.
What makes this version different from a basic baked chicken is that the marinade goes into the baking dish with the chicken and essentially bastes it as it cooks. I finish it under the broiler for the last 2 to 3 minutes to get that golden top you see in the photos.
I usually serve this with my Garlic Butter Rice so the pan juices have something to soak into, or with my Mashed Potatoes when we have company and I want something more substantial on the side.
Key Ingredients
All ingredients and their amounts are listed in the recipe card at the bottom of this post.
Chicken breast: I use boneless, skinless chicken breasts, typically three large ones that together weigh about 1 pound. The most important thing is that they are similar in size so they finish cooking at the same time. If yours are particularly thick, I recommend pounding them to an even thickness of about 3/4 inch before marinating. This is not strictly necessary, but it makes a real difference in how evenly they cook and how much of the marinade actually penetrates the meat.
Pro Tip: Chicken thighs also work beautifully here. They are naturally fattier and more forgiving in the oven. If you use boneless skinless thighs, reduce the bake time to about 22 to 25 minutes and check with a thermometer.
Fresh lemon juice: I always use freshly squeezed lemon juice for this recipe. Bottled lemon juice is more acidic and less bright in flavor, and since lemon is doing half the work in this marinade, the quality matters. You will need about 3 tablespoons, which is usually one large lemon. I add 4 or 5 thin slices of the same lemon to the baking dish before the chicken goes in. They soften in the oven and add a subtle bitterness that balances the garlic. Do not skip them.
Fresh rosemary sprigs: Three fresh rosemary sprigs go into the bag with the chicken and then transfer to the baking dish. They infuse the marinade and perfume the whole oven while the chicken bakes. I have made this with 1 teaspoon of dried rosemary when I ran out of fresh, and while it works, the flavor is flatter and less aromatic. Fresh is worth it for this one. Pull the sprigs out before serving unless you want to spend dinner picking woody bits out of your teeth.

How to Make This Lemon Rosemary Chicken Breast
Preheat your oven to 400°F. You will need one large casserole dish or baking dish, about 9×13 inches.
Step 1: Pat the chicken dry. Take the chicken out of the fridge and pat each breast dry with paper towels before making the marinade. Removing excess surface moisture helps the marinade actually coat and cling to the meat rather than just sliding off.
Step 2: Make the marinade. Add the olive oil, lemon juice, minced garlic, smoked paprika, dried oregano, salt, and pepper to a large zip-lock bag. Seal it and give it a quick squeeze to combine everything into a rough paste. Add the chicken breasts and rosemary sprigs to the bag, seal it again, and turn it a few times so the chicken is evenly coated. Place it flat in the fridge for a minimum of 1 hour and a maximum of 8 hours.

Step 3: Transfer to the baking dish. Lay the lemon slices across the bottom of the casserole dish first, then place the chicken breasts on top. Pour every drop of the marinade from the bag over the chicken. Tuck the rosemary sprigs alongside the breasts.
Step 5: Bake for 28 to 30 minutes. Bake uncovered at 400°F until an instant read thermometer inserted into the thickest part of the breast reads 165°F. Baking time will vary depending on the thickness of your chicken, which is why the thermometer matters more than the clock. A thin breast might be done at 22 minutes. A thick one might need 32.
Step 6: Broil for 2 to 3 minutes. This step is optional but I always do it. Switch the oven to broil and leave the dish in for 2 to 3 minutes until the top is golden and lightly caramelized. Watch it closely. It goes from golden to overdone fast. Remove the dish from the oven and let the chicken rest for 5 to 10 minutes before cutting. Resting lets the juice redistribute through the meat, and that is what keeps it juicy when you slice it.

Olivia’s Recipe Tips
Make a double batch if you are meal prepping. This chicken keeps well in an airtight container in the fridge for up to 4 days. I make a double batch most Sunday evenings, slice half of it for grain bowls and salads during the week, and shred the other half to freeze for soups. To freeze, let the chicken cool completely, shred it, and store it in a freezer-safe bag for up to 3 months.
Use the pan drippings as a sauce. After baking, the casserole dish holds a small amount of concentrated lemon-garlic pan juice. Spoon it over the sliced chicken before serving. It is not glamorous but it is genuinely delicious and costs nothing extra.

How good does this look!!! Loved reading the recipe.
Thanks 😉
Most Excellent, Did them on the grill. Gotta Watch Them close though or you’ll blow right by that 165 degree mark. I added a teaspoon of chili powder too.
Yes, when you cook them on the grill, you need to watch them close to not burn.
Try it on the grill!
Great 😉
I want to make this-but am a bit confused-whole garlic cloves and stems of rosemary? How does this “marinate” theres barely any fluid. Is this a rub? do you crush the garlic and put only rosemary leaves in? Because I can’t see anything getting marinated with whole cloves and stems of rosemary.
I think I used the wrong word. I fixed it in the recipe box for you. Thanks for pointing it out.
Should the total weight of the 2 chicken breasts be 330g or is that the individual weight?
This is for 2 chicken breast
Just made this for dinner. Absolutely delicious. I didn’t have fresh Rosemary, so used dried. Forgot to put slices of lemon on top of the chicken when roasting, but it was lemony enough. Chicken was tender and juicy. I marinated the breasts for four hours in the fridge. Combined it with the Mediterranean salad, and the two went together beautifully. Love the olive oil, fresh lemon juice and garlic dressing. Will definitely be making both the chicken and the salad again. But there are so many other delicious recipes to try 🙂 My daughter and I have started our no carb eating plan from today, so I can’t wait to try all the other delicious recipes on your site. Thank you so much XXX
Thanks a bunch for trying out the recipe! So glad you enjoyed the flavors, even with the dried rosemary and missed lemon slices. It sounds like the Mediterranean salad was a hit too!
