Step 1

Preheat oven to 375 degrees. Coat a 8x8 baking dish with nonstick cooking spray; set aside.

Step 2

In a small fry pan, heat 3 tablespoons of butter over medium-high heat and sauté the panko crumbs until just golden brown, stirring constantly, careful not to let them burn, about 2 minutes. Transfer to a bowl.

Step 3

In a medium saucepan, melt the remaining 4 tablespoons of butter over medium-high heat. Add in flour and whisk to make your roux; immediately after it’s combined, add in your half and half, whisking constantly until sauce thickens. Remove from heat and whisk in the salt, pepper, onion powder, coriander, and dry mustard.

Step 4

Evenly distribute half of the sliced carrots in the prepared baking dish; pour half of the white sauce over them, spreading to coat. Repeat layers one more time.

Step 5

Sprinkle the cheddar cheese on top, followed by the golden bread crumbs.

Step 6

Cover with foil and bake for 25 minutes. Remove foil and bake for another 15 minutes or until carrots are tender.

Step 7

Let stand 5 minutes before serving.
