My Italian aunt married into our Midwestern clan back in the early seventies, and every Sunday since, her kitchen has smelled like comfort and garlic and basil. This oven baked 3-ingredient basil mayo chicken is the dish she leans on when the whole family is coming and she doesn’t want to fuss, just visit. Chicken breasts get tucked under a creamy blanket of mayonnaise and fresh basil, then roasted until the top turns golden and speckled with herbs while the meat stays tender and juicy. It tastes like something that took all afternoon, but it’s simple enough to pull together after church or on a busy weeknight, which is exactly why it’s become our own Sunday tradition too.
Serve this basil mayo chicken straight from the foil-lined pan with the crispy, herb-flecked topping still intact. It’s lovely alongside buttered egg noodles or mashed potatoes to catch the extra juices, and a simple green salad or steamed green beans keeps the plate fresh and colorful. Crusty bread is perfect for swiping up any browned bits from the pan. If you’d like to lean into the Italian side of things, add roasted tomatoes or a dish of garlicky sautéed spinach on the table, and finish with a squeeze of lemon over the chicken just before serving.
Oven Baked Basil Mayo ChickenServings: 4
Ingredients
4 boneless, skinless chicken breasts (about 2 pounds total)
1 cup mayonnaise (not light or fat-free)
1/2 cup finely chopped fresh basil leaves, plus a few whole leaves for garnish
1 teaspoon kosher salt
1/2 teaspoon freshly ground black pepper
Directions
Preheat your oven to 400°F (200°C). Line a rimmed baking sheet with aluminum foil for easy cleanup, then lightly grease the foil with a bit of oil or nonstick spray so the chicken doesn’t stick.
Pat the chicken breasts dry on both sides with paper towels. This helps the mayo mixture cling and encourages a nice golden crust. Arrange the chicken in a single layer on the prepared baking sheet, leaving a little space between each piece.
In a medium bowl, stir together the mayonnaise, finely chopped fresh basil, salt, and pepper until the herbs are evenly distributed and the mixture is smooth and pale green with darker basil flecks.
Using a spoon or spatula, spread the basil mayo mixture evenly over the top of each chicken breast. Coat the tops generously, right out to the edges, but don’t bother with the underside; the mayo crust belongs on top where it can brown.
Place the baking sheet on the middle rack of the preheated oven. Bake for 22–28 minutes, depending on the thickness of your chicken breasts, until the tops are golden brown in spots and the edges look slightly crisp.
Check for doneness by inserting an instant-read thermometer into the thickest part of a breast; it should read 165°F (74°C). If the chicken needs more time, continue baking in 3–5 minute increments, checking again as needed.
For an extra golden, lightly crisp top like my aunt’s, move the pan to the upper third of the oven for the last 2–3 minutes of baking, or briefly switch on the broiler, watching closely so the mayo crust does not burn.
Remove the baking sheet from the oven and let the chicken rest on the pan for 5 minutes so the juices settle. Scatter a few torn fresh basil leaves over the top for color, then serve warm right from the foil-lined pan, spooning any pan juices over each piece.
Variations & Tips
You can tuck this recipe into your regular rotation and nudge it in different directions without losing its easy Sunday charm. For a garlicky version, stir 1–2 finely minced garlic cloves into the basil mayo before spreading it on the chicken. If you enjoy a little crunch, sprinkle 2–3 tablespoons of plain or seasoned breadcrumbs over the mayo-coated tops before baking; they will toast up beautifully and add texture without complicating the recipe. To lighten things slightly, you may swap up to half of the mayonnaise with plain full-fat Greek yogurt, though using all yogurt can make the topping weep and won’t brown as nicely. If you don’t have fresh basil on hand, you can use 2 tablespoons of dried Italian herb blend, but the flavor will be milder and the look less vibrant. This same basil mayo mixture can be spread over chicken thighs instead of breasts; just allow extra baking time and still cook to 165°F (74°C). For food safety, always keep raw chicken refrigerated until you’re ready to cook, wash your hands and any surfaces or utensils that touch the raw meat, and never reuse plates or cutting boards that held raw chicken without washing them thoroughly. If you mix the basil mayo in advance, store it covered in the refrigerator and use it within 24 hours. Leftover cooked chicken should be cooled, refrigerated within 2 hours, and eaten within 3–4 days, reheated until hot all the way through before serving.
