This oven baked 4-ingredient mayonnaise parmesan chicken is one of those hand-me-down family secrets that feels almost too easy to be this good. My aunt taught me this trick when I first learned to cook: a simple mayo and parmesan coating locks in the juices so the chicken stays incredibly tender, while the top turns beautifully golden and a little bit crispy. With just four everyday items and a foil-lined pan, you get juicy poultry with a perfectly golden crust every single time—no fancy skills, no long marinade, just real comfort food that works on a busy weeknight.
This chicken is lovely with simple sides that soak up the extra pan juices—think buttered egg noodles, mashed potatoes, or a pan of roasted vegetables cooked on the rack below. A crisp green salad or steamed green beans help balance the richness of the mayo and cheese. If you’re feeding kids, serve it with corn, carrot sticks, or garlic bread for dipping. Leftovers are great sliced over salad, tucked into a sandwich, or chopped into a quick pasta the next day.
Oven Baked 4-Ingredient Mayonnaise Parmesan ChickenServings: 4
Ingredients
4 boneless, skinless chicken breasts (about 2 pounds total)
1 cup mayonnaise
1/2 cup grated Parmesan cheese (the dry, shaker-can style works great)
1 teaspoon garlic powder
Cooking spray or a little oil for the foil (optional, for easier cleanup)
Salt and black pepper to taste (optional, but recommended)
Directions
Preheat your oven to 400°F (200°C). Line a rimmed baking sheet with aluminum foil for easy cleanup, then lightly coat the foil with cooking spray or a thin smear of oil so the cheesy coating doesn’t stick too much.
Pat the chicken breasts dry with paper towels so the coating will cling well. If any pieces are very thick on one end, gently pound them to an even thickness so they cook at the same rate. Season both sides lightly with salt and black pepper if using.
In a medium bowl, stir together the mayonnaise, grated Parmesan cheese, and garlic powder until you have a thick, creamy mixture. This is your magic coating that keeps the chicken juicy and builds that golden crust.
Lay the chicken breasts on the prepared baking sheet, leaving a little space between each piece. Using the back of a spoon, spread a generous layer of the mayo-parmesan mixture over the top of each chicken breast, coating the tops and sides well. The layer should be fairly thick and a bit uneven—that’s what gives you those crispy, browned spots later.
Place the baking sheet on the middle rack of the preheated oven. Bake for 25–30 minutes, or until the chicken is cooked through and the tops are bubbling, golden brown, and slightly crisp around the edges. The internal temperature should reach 165°F (74°C) in the thickest part of the breast when checked with an instant-read thermometer.
If you’d like a deeper golden crust, switch the oven to broil for the last 1–2 minutes, watching closely so the cheese doesn’t burn. The coating should look toasted in spots with a creamy layer underneath and some juices bubbling around the chicken on the foil.
Remove the pan from the oven and let the chicken rest on the baking sheet for 5 minutes. This helps the juices settle so every bite stays moist. Use tongs to lift each breast from the foil—there will be some delicious bubbling juices underneath—and serve hot, spooning a little of the pan juices over the top if you like.
Variations & Tips
For picky eaters, you can dial back the garlic powder or skip it altogether and just use the mayonnaise and Parmesan. If your family likes a little extra flavor, add 1 teaspoon of dried Italian seasoning or a pinch of paprika to the mayo mixture. You can also sprinkle a tablespoon or two of plain breadcrumbs over the coated chicken before baking for an even crispier, more textured top. If you prefer dark meat, this method works well with boneless, skinless chicken thighs; just adjust the cooking time as needed and make sure the internal temperature reaches 165°F (74°C). For a lighter version, you can swap part of the mayonnaise with plain Greek yogurt (start with half mayo, half yogurt), keeping in mind the topping may brown a bit differently and can be slightly tangier. Food safety tips: Always wash your hands, utensils, and any surfaces that touch raw chicken with hot, soapy water. Do not rinse raw chicken, as this can spread bacteria around your sink area. Use a separate cutting board for raw meat if possible. Make sure the chicken reaches an internal temperature of 165°F (74°C) before serving, and refrigerate leftovers within 2 hours. Leftover chicken should be reheated to 165°F and eaten within 3–4 days for best quality.
