My neighbor Ruth, who’s been farming and feeding a big family longer than I’ve been buying butter by the pound, shared this little secret with me one Sunday after church. She walked over with a glass baking dish covered in an old flour sack towel, and when she pulled it back, the chicken was bubbling away in its own juices under a golden, garlicky Parmesan crust. I was sure it had to be marinated or fussed over, but she just laughed and told me it was only four ingredients and a hot oven. The meat stayed so tender and juicy it reminded me of the Sunday dinners my mother used to make back on the farm, when simple pantry staples did all the heavy lifting. This is the kind of recipe you make on a busy weeknight or when company drops by, because it feels special but doesn’t ask much of you at all.
This garlic Parmesan chicken is right at home with the sort of sides most Midwestern kitchens already have on hand. Spoon those buttery pan juices over a pile of mashed potatoes or egg noodles, and add a simple vegetable like buttered green beans, sweet corn, or roasted carrots. A crisp green salad with a tangy dressing helps balance the richness of the cheesy crust. If you like bread on the table, warm dinner rolls or a slice of crusty farmhouse bread are perfect for sopping up every last drop from the baking dish.
Oven Baked 4-Ingredient Garlic Parmesan Chicken
Servings: 4

Ingredients
4 boneless, skinless chicken breasts (about 2 pounds total)
1 cup mayonnaise (regular, not low-fat)
3/4 cup grated Parmesan cheese (the dry, sandy kind in a can or finely grated from a wedge)
3 cloves garlic, finely minced or pressed
Directions
Preheat your oven to 375°F (190°C). Set out a 9x13-inch glass baking dish so it’s ready. There’s no need to grease it; the topping has enough richness to keep things from sticking.
Pat the chicken breasts dry with paper towels. This helps the topping cling and encourages a nice, golden crust. Lay the chicken breasts in a single layer in the glass baking dish, leaving just a little space between each piece.
In a medium bowl, stir together the mayonnaise, grated Parmesan cheese, and minced garlic until you have a thick, even mixture. This is the neighbor’s little secret: the mayonnaise locks in the juices while the Parmesan and garlic give it flavor and color.
Spoon the garlic-Parmesan mixture evenly over the tops of the chicken breasts. Use the back of the spoon to spread it all the way to the edges of each piece, making sure every bit of the top surface is covered. Don’t worry if some slips down the sides; it will mingle with the drippings and make a tasty sauce in the bottom of the dish.
Place the baking dish on the middle rack of the preheated oven. Bake for 25 to 35 minutes, or until the chicken is cooked through and very tender. The exact time will depend on the thickness of your chicken breasts. You’re looking for the topping to be set and lightly browned and the juices around the chicken to be bubbling. The internal temperature should reach 165°F (74°C) when checked with an instant-read thermometer in the thickest part of a breast.
If you’d like a deeper golden brown crust, move the dish to the top rack and broil on high for 2 to 3 minutes at the end of baking. Watch closely so the cheese doesn’t burn; you just want a few toasty spots on top.
Remove the baking dish from the oven and let the chicken rest for 5 to 10 minutes. During this time, the juices settle back into the meat, keeping it extra moist, and the cheesy topping firms up a bit. Serve the chicken straight from the glass dish, spooning some of the garlicky, cheesy pan juices over each piece on the plate.
Variations & Tips
For a little extra flavor without adding more ingredients, use a coarser, freshly grated Parmesan and a very sharp garlic; both will give the topping more character. If your chicken breasts are especially large and thick, you can slice them horizontally into cutlets for more even cooking and an even higher ratio of golden crust to juicy meat. To stretch the dish for a crowd, cut the baked chicken into thick slices or chunks and toss with hot cooked pasta, using the pan juices as a simple sauce. If you prefer darker meat, this same method works well with boneless, skinless chicken thighs; just allow a few extra minutes of baking time and check for doneness. Leftovers reheat nicely covered in a low oven (about 300°F/150°C) until warmed through; add a spoonful of water or chicken broth to the dish before reheating to keep everything moist. For those watching salt, choose a lower-sodium Parmesan and season the table, not the dish, as the cheese and mayonnaise already bring plenty of flavor.
