Oven Baked 3 Ingredient Chicken: The Simplest, Juiciest Chicken You Will Ever Make

Found this in my mother‑in‑law’s recipe box from 1965 and now I understand why she made it every single Sunday. That is the kind of recipe that becomes family legend — the one written on a faded index card, stained with butter and love, passed down through generations. And when you finally make it, you realize why it stood the test of time.

This Oven Baked 3‑Ingredient Chicken is almost impossibly simple. Just chicken, creamy mayonnaise, and grated Parmesan cheese. No complicated marinades. No brining. No constant flipping or basting. Yet the result is the most tender, juicy, golden‑brown chicken you have ever pulled from your oven. The mayonnaise creates a crisp, flavorful crust while locking in every drop of moisture. The Parmesan adds a nutty, salty depth.

It is a vintage recipe that deserves a comeback. And once you try it, you will understand why it graced Sunday dinner tables for decades.

In this guide, you will learn the complete 3‑ingredient recipe, the science behind why mayonnaise makes the best chicken, pro tips for perfect results, delicious variations, storage advice, and why this humble dish will become your new weeknight hero.

Why This 3‑Ingredient Chicken Works So Well

You might be skeptical. Mayonnaise on chicken? No eggs? No breadcrumbs? How can three simple ingredients produce something so juicy and flavorful?

The secret is mayonnaise. It is not just a condiment; it is an emulsion of oil, egg yolks, and vinegar or lemon juice. When you coat chicken with mayonnaise and bake it, the oil bastes the meat continuously, keeping it incredibly moist. The egg proteins help create a golden, crispy crust. The vinegar or lemon juice adds a subtle tang that brightens the flavor. And when you mix in Parmesan cheese, it forms a savory, nutty coating that is utterly addictive.

Here is why you will love it:

· Only 3 ingredients – Chicken, mayonnaise, Parmesan cheese.
· No prep work – No chopping, no marinating, no brining.
· Incredibly juicy – The mayonnaise locks in moisture.
· Crispy, golden crust – Bakes up beautiful every time.
· Budget‑friendly – Uses economical chicken pieces.
· Kid‑approved – Mild, creamy, and delicious.
· Vintage charm – A taste of old‑fashioned Sunday dinner.

This is the chicken you will make when you need a reliable, foolproof meal that everyone loves.

The Complete 3‑Ingredient Oven Baked Chicken Recipe

This recipe serves 4–6 people. Use bone‑in, skin‑on chicken pieces for the best results, but boneless, skinless works too.

Ingredients

· 2 to 3 pounds (900g–1.4kg) chicken pieces – thighs, drumsticks, or a mix of your favorites (bone‑in, skin‑on recommended)
· 1 cup (240g) full‑fat mayonnaise (Duke’s, Hellmann’s, or Best Foods)
· 1 cup (100g) finely grated Parmesan cheese (the green can or fresh)
· Optional: ½ teaspoon black pepper, ½ teaspoon garlic powder (not counted in the 3 – but highly recommended)

Equipment

· 9×13‑inch baking dish or rimmed baking sheet
· Parchment paper or foil (for easy cleanup)
· Mixing bowl

Step‑by‑Step Instructions

Step 1 – Preheat and Prepare

Preheat your oven to 375°F (190°C). Line a baking dish or baking sheet with parchment paper or aluminum foil for easy cleanup. Lightly grease the paper if using foil.

Step 2 – Mix the Coating

In a medium bowl, combine the mayonnaise and grated Parmesan cheese. Stir until well blended. The mixture will be thick and paste‑like. If you are using optional seasonings, add them now.

Step 3 – Coat the Chicken

Pat the chicken pieces dry with paper towels. Using a spatula or your hands (wear gloves if you prefer), spread the mayonnaise‑Parmesan mixture evenly over each piece of chicken. Do not worry about being perfect; a thick, even coat is all you need.

Step 4 – Arrange in the Dish

Place the coated chicken pieces in the prepared baking dish, skin‑side up if using bone‑in pieces. Leave a little space between each piece so the heat circulates.

Step 5 – Bake

Bake at 375°F for 35–45 minutes for boneless pieces, or 45–55 minutes for bone‑in pieces. The chicken is done when the internal temperature reaches 165°F (74°C) in the thickest part, and the coating is golden brown and crispy. If you want an extra crispy top, switch to broil for the last 2–3 minutes, watching carefully.

Step 6 – Rest and Serve

Let the chicken rest in the pan for 5–10 minutes before serving. This allows the juices to redistribute. Serve warm with your favorite sides.

Pro Tips for the Juiciest 3‑Ingredient Chicken

Use Full‑Fat Mayonnaise

Low‑fat or fat‑free mayonnaise has more water and less oil, which can make the coating soggy and the chicken dry. Full‑fat mayo is essential.

Bone‑In, Skin‑On Is Best

The bone helps conduct heat and keeps the meat moist. The skin becomes extra crispy under the mayo‑Parmesan crust. However, boneless, skinless breasts or thighs also work; just reduce cooking time.

Do Not Overbake

Chicken dries out quickly after reaching 165°F. Use a meat thermometer and remove it from the oven as soon as it hits temperature.

Season the Mayo Mixture

Mayonnaise and Parmesan already have salt, but a pinch of black pepper, garlic powder, onion powder, or paprika takes this chicken to the next level.

For Extra Crunch

Mix in ¼ cup of panko breadcrumbs or crushed pork rinds (for keto) with the Parmesan. Press the coating firmly onto the chicken.

Make It Spicy

Add ½ teaspoon of cayenne pepper or red pepper flakes to the mayo mixture. Or use a spicy mayo like sriracha mayo (reduce plain mayo to ¾ cup, add ¼ cup sriracha mayo).

Let the Chicken Rest

Do not skip the resting step. Cutting into the chicken immediately will release the juices and result in dry meat.

Delicious Variations (Same 3‑Ingredient Formula)

Once you master the classic Parmesan chicken, try these easy twists.

1. Garlic Parmesan Chicken

Add 1 tablespoon of minced fresh garlic (or 1 teaspoon garlic powder) to the mayo mixture. The garlic infuses the entire dish.

2. Italian Herb Chicken

Add 1 tablespoon of dried Italian seasoning to the mayo mixture. Use grated Pecorino Romano instead of Parmesan for a sharper flavor.

3. Spicy Buffalo Chicken

Mix ½ cup of buffalo sauce with ½ cup of mayonnaise. Use ½ cup of Parmesan. The result is tangy, spicy, and creamy. Serve with ranch dressing.

4. Lemon Dill Chicken

Add 2 tablespoons of fresh lemon juice, 1 tablespoon of lemon zest, and 1 tablespoon of fresh dill (or 1 teaspoon dried). The bright, fresh flavors are perfect for spring.

5. Everything Bagel Chicken

Mix 2 tablespoons of everything bagel seasoning into the mayonnaise. Use Parmesan as usual. The coating becomes incredibly flavorful and crunchy.

6. Keto / Low‑Carb Chicken

This recipe is already low in carbs. Use full‑fat mayo and Parmesan. For extra crunch, mix in crushed pork rinds. Serve with cauliflower mash.

7. Dairy‑Free Chicken

Use a dairy‑free mayonnaise (like Vegenaise) and substitute the Parmesan with ½ cup of nutritional yeast mixed with ¼ cup of almond flour. The coating will be different but still delicious.
