This savory sweet potato casserole features tendersweet potatoes and fresh herbs topped with buttery breadcrumbs and baked to perfection. It's perfect for busy weeknights or your next Thanksgiving feast!
Prepare a 9X13 inch baking dish by spraying it with nonstick cooking spray. Preheat the oven to 400 degrees fahrenheit.
Pour the cubed sweet potatoes into the prepared baking dish in an even layer.
In a medium bowl, whisk together the butter, chicken stock, thyme, oregano, parsley, garlic, salt, and pepper. Briskly whisk in the flour, ensuring there are no clumps.
In a separate bowl, mix together the breadcrumbs, parmesan cheese, parsley, and olive oil. Be sure to mix everything well, evenly distributing the olive oil.
Pour the liquid mixture over the potatoes in the baking dish. Top the potatoes with the crispy topping, evenly distributing it over the casserole.
Bake for 45 minutes or until the potatoes are tender and the topping is golden brown. Check the casserole after 30 minutes and cover with foil if the topping is getting too browned.
