Easy Chicken Parmesan with Sourdough Breadcrumbs (No Flour or Egg Needed)
If you’re looking for an easy Chicken Parmesan recipe that’s crispy, flavorful, and simple enough for a busy weeknight, this version is for you. Instead of the traditional flour-and-egg breading, this recipe uses a thin layer of mayonnaise to help a seasoned mixture of sourdough breadcrumbs and Parmesan cheese stick to the chicken. The result is juicy, tender chicken with a golden, crunchy coating, topped with marinara sauce and melted mozzarella cheese. It’s a comforting family dinner that comes together with minimal mess and is a wonderful way to use homemade sourdough breadcrumbs.

My Homemade Chicken Parmesan….Easy and No Waste
There are some recipes that become favorites because they’re fancy, and then there are recipes that become favorites because they simply work.
This Chicken Parmesan falls into the second category.
Like many home cooks, I used to make Chicken Parmesan the traditional way…dipping each piece of chicken into flour, then egg, then breadcrumbs. The results were always delicious, but the process left behind multiple bowls, a messy countertop, and extra time spent cleaning up afterward.
A few years ago, I started experimenting with a simpler method using mayonnaise instead of the flour-and-egg coating.
The result surprised me.
The chicken stayed incredibly juicy and tender, while the breadcrumb coating baked up golden brown and crispy. Even better, the whole process was quicker and less messy.
One of my favorite things about this recipe is that it gives me another way to use homemade sourdough breadcrumbs. Whenever a loaf of sourdough is getting a little stale, I turn it into breadcrumbs or croutons and freeze them for later. It feels good knowing that nothing goes to waste, and the sourdough adds wonderful flavor to the finished dish.
Served alongside homemade fettuccine Alfredo, sourdough garlic bread, and a glass of sparkling water kefir, this meal feels cozy, comforting, and special without requiring hours in the kitchen (That is a HUGE win in my book!)

Ingredients
For the Chicken:
- 2 large boneless skinless chicken breasts
- ½ cup mayonnaise
- Cooking spray or olive oil spray
The Breadcrumb Coating:
- ½ cup sourdough breadcrumbs
- ½ cup grated Parmesan cheese
- ½ teaspoon dried oregano
- 1 teaspoon salt
- ½ teaspoon black pepper
For Topping:
- Marinara sauce (about ½ to 1 cup, depending on preference)
- 1 cup shredded mozzarella cheese
- Additional oregano for garnish (optional)
How to Make Easy Chicken Parmesan
Step 1: Prepare the Chicken
Preheat your oven to 400°F.
Slice each chicken breast horizontally to create thinner cutlets.
Place the chicken between two sheets of plastic wrap and gently pound to an even thickness using a meat mallet.
This step helps the chicken cook evenly and stay tender.
Step 2: Make the Breadcrumb Mixture
In a shallow bowl, combine:
- Sourdough breadcrumbs
- Parmesan cheese
- Oregano
- Salt
- Pepper
Mix well.
Step 3: Coat the Chicken
Spread a thin layer of mayonnaise on both sides of each chicken cutlet. I like to paint it on both sides with a basting brush.
Press the chicken into the breadcrumb mixture, coating both sides thoroughly.
Place the coated chicken on a baking sheet lined with parchment paper. I personally prefer to use this pan because it allows the warm oven air to get under the chicken creating a crispier bottom layer.
Step 4: Bake
Lightly spray the tops of the chicken with cooking spray or olive oil spray.
Bake for approximately 15 minutes or until the chicken reaches an internal temperature of 165°F using a meat thermometer.
Step 5: Add Sauce and Cheese
Remove the pan from the oven.
Spoon marinara sauce over each piece of chicken, leaving some of the crispy edges exposed.
Sprinkle mozzarella cheese evenly over the top.
Step 6: Finish Baking
Return the chicken to the oven for 3–5 minutes or until the cheese is melted.
For lightly browned cheese, turn on the broiler for 1–2 minutes, watching carefully.
Allow the chicken to rest for several minutes before serving.
Tips for Success
- Pound the chicken evenly for consistent cooking.
- Leave some crispy edges uncovered by sauce.
- Use freshly grated Parmesan when possible.
- Don’t skip the resting time after baking.
- Watch closely if using the broiler.
- Homemade sourdough breadcrumbs provide the best flavor and texture.
Easy Chicken Parmesan with Sourdough Breadcrumbs (No Flour or Egg Needed)
Ingredients
- 2 chicken breasts
- 1/2 cup mayonnaise
- 1/2 cup parmesan cheese shredded
- 1/2 cup sourdough breadcrumbs or regular breadcrumbs
- 1/2 tsp dried oregano
- 1 tsp salt
- 1/2 tsp black pepper
- 1 cup mozzarella shredded
- chopped oregano (optional) for garnish
- olive oil spray for extra crispiness
Instructions
- Preheat your oven to 400 degrees.
- Cut the chicken breasts in half horizontally to make 4 chicken pieces. Place in between 2 sheets of plastic wrap and gently pound chicken with a meat mallet. This will help the chicken cook more evenly.
- In a large bowl, combine oregano, parmesan cheese, sourdough breadcrumbs, salt, and pepper. Mix well.
- Coat the chicken with mayonnaise on each side then place in breadcrumb dish. Gently press down to coat each side of the chicken with the breadcrumb mixture. Then place on a pan.
- Bake in the oven for about 15 minutes or until the internal temperature reaches 165.
- Remove from the oven and spoon marinara sauce over each piece of chicken. Top with mozzarella cheese and place back in the oven.
- Bake for an additional 3 minutes or until the cheese melts. You can choose to broil for a couple of minutes but make sure you stay close to prevent burning.
- Remove from oven and let sit for about 5 minutes so the juices can redistribute inside the chicken. Serve over your favorite pasta with marinara sauce, alfredo, or a side of vegetables. Enjoy!
Notes
- Sourdough breadcrumbs: Homemade sourdough breadcrumbs work best for flavor and texture, but any plain or Italian-style breadcrumbs can be used. This is also a great way to use up stale sourdough bread.
- Even chicken thickness matters: Pounding the chicken to an even thickness helps it cook evenly and stay tender. Don’t skip this step.
- Don’t overload the sauce: Add just enough marinara to complement the chicken while keeping some crispy edges exposed for texture.
- Cheese tip: Freshly shredded mozzarella melts better than pre-shredded cheese, but either will work.
- Crispier finish: For extra crispiness, lightly spray the breadcrumb coating with olive oil before baking.
- Broiler option: You can broil for 1–2 minutes at the end to brown the cheese, but watch closely to prevent burning.
- Make ahead: You can bread the chicken ahead of time and refrigerate it for up to 6–8 hours before baking.
- Serving idea: This is delicious served with pasta, Alfredo sauce, marinara, or sourdough garlic bread for a full cozy meal.
- Storage: Store leftovers in the fridge for up to 4 days. Reheat in the oven to keep the coating crisp.
