Preheat your oven to 425°F. This high temperature is essential for perfectly roasting your vegetables and creating that golden crust on the chicken.
Lightly spray an 18×13-inch large rimmed sheet pan with nonstick spray. This will prevent any sticking and ensure easy cleanup!
On the prepared pan, toss together the green beans, potatoes, olive oil, garlic, salt, and pepper to taste. Spread the vegetables out in a single layer, making sure they have space to roast evenly.
Bake until partially cooked, about 20 minutes. Look for the vegetables to soften slightly but not fully cooked—this ensures they will finish cooking alongside the chicken.
While the vegetables are cooking, season the chicken with the salt and pepper to taste. This step is crucial, as it infuses the meat with flavor.
Put the flour in a shallow plate, the egg in a medium bowl, and the Panko breadcrumbs in another shallow plate. This setup makes the dredging process easy and efficient.
Dredge each chicken cutlet lightly in the flour, then dip it in the egg, shaking off any excess. This creates a base that helps the breadcrumbs adhere.
Dredge the chicken in the Panko breadcrumbs, lightly pressing to evenly coat. Make sure each cutlet is generously coated for maximum crunch.
Set the breaded chicken aside on a plate while you prepare the vegetables. The waiting time allows the coating to adhere better during cooking.
Once the vegetables are partially cooked, remove the pan from the oven. Stir them together, pushing them to one side. This creates space for the chicken.
Place the chicken on the other side of the pan and spray the tops with olive oil spray. This will give the schnitzel a beautiful golden color.
Return the pan to the oven and bake until the chicken is golden and the potatoes are cooked through, about 15 minutes. Keep an eye on the chicken’s color as it should be a beautiful golden-brown.
Switch the oven to broil and broil until the top of the chicken is browned slightly, about 1 to 2 minutes. This step adds that final crispy finish.
Remove the pan from the oven and squeeze the lemon half over the vegetables. This brightens the flavors and adds a delicious zing.
Top the chicken with the capers and parsley, and serve with the lemon wedges on the side. Enjoy your beautifully plated Crispy Chicken Schnitzel!
