Preheat your oven to 425°F for roasting the broccoli and to prepare for finishing the chicken.
Pat the chicken breast dry and lightly season with salt, pepper, and your favorite dried herbs if desired.
In a shallow dish, spread out the whole wheat breadcrumbs. Dip the chicken into the breadcrumbs, ensuring an even, light coating.
Place the breaded chicken on a baking sheet lined with parchment paper. Lightly sprinkle the grated parmesan cheese over the top of the chicken.
Bake the chicken in the preheated oven for 18-20 minutes or until cooked through and crispy on the outside.
While the chicken bakes, chop the broccoli into florets. Toss the broccoli with olive oil, salt, and pepper, then spread it on another baking sheet.
Roast the broccoli in the oven for approximately 12-15 minutes, until tender and slightly charred at the edges.
Once the chicken is nearing completion, warm the marinara sauce in a small saucepan over low heat or in the microwave.
Remove the chicken and broccoli from the oven. Drizzle the warm marinara sauce over the chicken or serve it on the side as a dip.
Plate the crispy chicken parmesan alongside the roasted broccoli and enjoy a balanced, flavorful meal.
