Ingredients for baked chicken breast with tomatoes
Juicy chicken breasts and caramelized tomatoes transform a simple weeknight dinner into restaurant-quality perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless, Skinless Chicken Breasts 🍗 | 1 ½ lb | Even thickness for even cooking |
| Large Roma Tomatoes 🍅 | 4 whole | Halved lengthwise for even roasting |
| Buttermilk 🥛 | 1 cup | Full-fat for optimal tenderness |
| Extra-Virgin Olive Oil 🫒 | ½ cup | High-quality for flavor infusion |
| Garlic Cloves 🧄 | 4 cloves | Minced for aromatic depth |
| Fresh Rosemary 🌿 | 1 tbsp | Chopped, for herbal complexity |
| Fresh Thyme 🌿 | 1 tbsp | Leaves only, for bright flavor |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | For brining and seasoning |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked for heat |
| Fresh Lemon Juice 🍋 | 2 tbsp | Brightens tomato flavors |
| All-Purpose Flour 🌾 | 2 tbsp | For dredging chicken |
| Crushed Red Pepper Flakes 🌶️ | ¼ tsp | Optional for subtle heat |
The chicken breasts are the foundation, so choose even-sized pieces—thickness matters for consistent doneness. Whole Foods or your local butcher often carry pre-trimmed cuts, but if buying whole breasts, trim excess fat and pound to equal thickness with a meat mallet. For the tomatoes, Roma variety holds up best to roasting, developing that concentrated sweetness. Fresh herbs like rosemary and thyme should be bright green and fragrant—if they smell dull, they're past their prime. The buttermilk brine is non-negotiable for tenderness, but if you're short on time, substitute with plain yogurt or milk plus 1 tbsp vinegar.
No buttermilk? Plain yogurt or milk with 1 tbsp vinegar works in a pinch. For the tomatoes, cherry tomatoes can replace Roma if needed, but they'll release more juice. The olive oil should be extra-virgin—cheap oil will make the dish taste flat. If you prefer less acidity, reduce the lemon juice to 1 tbsp. The crushed red pepper is optional, but if using, toast it lightly in a dry pan first to deepen its flavor. For extra crispy skin, pat the chicken completely dry before dredging in flour—this step is crucial for that perfect oven finish.
Brined chicken stays fresh in the fridge for 2 days before baking, but use it sooner for peak tenderness. Fresh herbs should be wrapped in damp paper towels and stored in a sealed container for up to 5 days. The baked dish reheats beautifully—350°F for 10-12 minutes restores moisture without drying out. For meal prep, portion the chicken and tomato sauce separately; the sauce thickens when reheated, so add a splash of water or broth if needed. Leftovers keep for 4 days in the fridge or 3 months frozen.

Step-by-step instructions for baked chicken breast with tomatoes
This method delivers perfectly juicy chicken with caramelized tomatoes—no dryness, no bitterness, just balanced flavor.
Marinate the Chicken in Buttermilk for Maximum Tenderness
Place the 1.5 lb boneless, skinless chicken breasts in a shallow dish and pour the 1 cup buttermilk over them. Add 1.5 tsp Diamond Crystal kosher salt, 0.5 tsp ground black pepper, and 0.25 tsp crushed red pepper flakes. Gently turn the chicken to coat evenly, ensuring the buttermilk penetrates all surfaces. Cover and refrigerate for at least 2 hours—this acid marinade breaks down muscle fibers, guaranteeing juicy results.
I always use full-fat buttermilk here because the fat content helps retain moisture during baking. If you're short on time, marinate for 30 minutes minimum, but don't skip this step entirely—it's what prevents dry chicken. The buttermilk will curdle slightly as it sits, which is normal and actually improves texture.
Prepare the Tomato-Garlic Herb Mixture
Preheat your oven to 400°F. Halve the 4 whole large Roma tomatoes lengthwise and place them in a bowl. Add the 4 cloves minced garlic, 1 tbsp chopped fresh rosemary, 1 tbsp fresh thyme leaves, and 2 tbsp fresh lemon juice. Drizzle with 0.25 cup extra-virgin olive oil (half the total amount) and toss gently to combine. The tomatoes should be well-coated but not broken apart.
This preparation creates a flavorful bed for the chicken while the tomatoes roast into sweet, concentrated bursts. The lemon juice brightens their natural acidity, and the herbs infuse their oils. Spread the tomato mixture evenly in a 9x13-inch baking dish—this gives them room to caramelize without steaming.
Dredge and Arrange the Chicken
Remove the chicken from the buttermilk and let any excess drip off. Place the 2 tbsp all-purpose flour in a shallow dish and press each chicken breast lightly on both sides to create a thin, even coating. This flour barrier helps develop a golden crust during baking while keeping the meat moist.
Arrange the chicken breasts on top of the tomato mixture in the baking dish, slightly overlapping if needed. Pour the remaining 0.25 cup extra-virgin olive oil evenly over the chicken and tomatoes. The oil will baste the chicken as it bakes, adding richness and preventing dryness. Bake uncovered for 25-30 minutes until the chicken reaches 165°F internally and the edges are golden brown.
Rest and Serve with Roasted Tomatoes
Transfer the chicken to a cutting board and tent loosely with foil. Let it rest for 10 minutes—this crucial step allows the juices to redistribute, ensuring every bite stays moist. Meanwhile, spoon the roasted tomatoes from the baking dish over the chicken. The tomatoes should be tender with slightly blistered edges and concentrated sweetness.
Slice the chicken against the grain for maximum tenderness and serve immediately with the roasted tomatoes spooned alongside. The buttermilk marinade creates a subtle tang, the tomatoes add natural sweetness, and the herbs elevate both components. For extra flavor, drizzle any accumulated pan juices over the top before serving.
Pro Tips For Making Baked Chicken Breast With Tomatoes
- BRINE THE CHICKEN FIRST: I learned this the hard way—dry chicken breasts bake unevenly. Soak them in buttermilk for 30 minutes (or overnight if you’re patient) before baking. The acid tenderizes while the fat keeps them juicy, and the crust forms better when you finally hit 400°F.
- SLICE TOMATOES THICK: Thin slices turn to mush. Cut Roma tomatoes into ½-inch thick half-moons—thick enough to hold shape but still cook through. Arrange them cut-side up on the chicken so they caramelize instead of steam into oblivion.
- USE A THERMOMETER: That 165°F rule isn’t optional here. Chicken breasts hit 160°F internally before they’re done—wait until the thermometer reads 165°F in the thickest part. Overcooking dries them out, and undercooking is a food-safety nightmare.
- COOK GARLIC IN OIL FIRST: Sear minced garlic in olive oil for 2 minutes until fragrant before adding tomatoes. This builds flavor without burning, and the oil carries it straight into the chicken. (Yes, even if you’re impatient like me—don’t skip it.)
Make-ahead tips for this dish
Prep Ahead for Stress-Free Cooking
The buttermilk brine can be done up to 2 days in advance—just store the chicken in an airtight container in the fridge. I like to prep this the night before so the chicken is ready to bake in the morning.
For the tomatoes, you can chop the garlic, herbs, and lemon juice into a separate container and store them in the fridge for up to 3 days. This way, you only need to halve the tomatoes and assemble everything when you're ready to bake. 💡
Freezer-Friendly Components
You can freeze the brined chicken for up to 2 months—thaw it overnight in the fridge before baking.
For the tomato mixture, toss the halved tomatoes with half the olive oil, garlic, herbs, and lemon juice, then freeze in a single layer on a tray before transferring to a freezer bag. When ready to cook, thaw in the fridge overnight and proceed with the recipe.
The texture stays intact, though the tomatoes may release slightly more juice when thawed. ❄️
Tomato Sauce Prep Shortcut
Roast the tomatoes ahead of time and store them in their juices in a sealed container in the fridge for up to 3 days. Reheat gently in a saucepan over low heat for 5-7 minutes until warmed through.
This works perfectly for meal prep—simply reheat the sauce and serve it alongside freshly baked chicken. The flavors deepen over time, making this an ideal make-ahead strategy for busy weeks.
Chicken Storage for Leftovers
After baking, let the chicken cool completely before storing in an airtight container with the tomato sauce. It keeps in the fridge for 4 days—reheat the chicken and sauce separately to avoid sogginess. For freezing, portion the chicken and sauce into individual meal-sized containers.
When reheating from frozen, bake at 350°F for 15-20 minutes until the chicken reaches 165°F internally. The sauce may thicken slightly, so add a splash of water or broth if needed.
Herb Substitutions for Convenience
If fresh herbs aren't available, use 1 tsp dried rosemary and 1 tsp dried thyme instead of fresh. Store dried herbs in airtight containers in a cool, dark place for up to 6 months.
For even more convenience, make a herb blend by combining the dried herbs with ½ tsp salt and store it in a small jar. This way, you always have the perfect seasoning mix ready for future meals. 🌿

Frequently asked questions
Why does the recipe call for buttermilk instead of regular milk?
The buttermilk's acidity tenderizes the chicken by breaking down muscle fibers, while its fat content helps retain moisture during baking. Regular milk lacks this dual action—it won't give you the same juicy, crispy-skinned results. For a quick substitute, mix 1 cup milk with 1 tbsp vinegar or lemon juice and let it sit for 5 minutes to curdle.
Can I use cherry tomatoes instead of Roma tomatoes?
Yes, but expect more juice and less caramelization. Cherry tomatoes will burst open during baking, creating a saucy texture rather than concentrated sweetness. If using them, reduce the lemon juice to 1 tbsp and add ½ tsp sugar to balance the acidity. For the best results, roast them separately on a baking sheet first to prevent a watery dish.
How do I know when the chicken is fully cooked?
Use a meat thermometer to check the thickest part of the breast—it should read 165°F. The edges will be golden brown, but color alone isn't reliable. For even cooking, place thicker pieces on the outer edges of the baking dish and thinner ones toward the center. If your chicken browns too quickly, tent it loosely with foil after 15 minutes.
What's the best way to reheat leftovers without drying out the chicken?
Reheat the chicken and tomato sauce separately. Place chicken pieces in a baking dish with 1 tbsp water or broth, cover with foil, and bake at 350°F for 10-12 minutes until reaching 165°F. Warm the sauce separately over low heat—it may thicken, so thin with water if needed. Never microwave uncovered, as it dries out the meat.
Can I make this recipe in a slow cooker instead of the oven?
Not ideal for this dish—slow cooking would make the chicken rubbery and the tomatoes mushy. However, you can adapt it by baking the chicken first (as directed), then shredding it and mixing with the roasted tomatoes in a slow cooker on low for 1-2 hours for a different texture. For best results, stick with the oven method for that perfect crispy skin and caramelized tomato flavor.
