How to make Asparagus Lemon Rice Casserole
Preheat oven to 400°F (200°C) and lightly grease an 9×9-inch baking dish.
- Prepare the asparagus by removing and discarding the tougher, woody, light colored ends. Cut the remainder in ½ inch pieces. Set aside.
- Whisk together mascarpone, milk, lemon zest, lemon juice, Dijon mustard, parmesan, salt, and pepper until smooth.
- Combine in a large bowl, the cooked rice, asparagus pieces, and the mascarpone sauce. Stir until everything is well coated by the sauce.
- Transfer the asparagus rice mixture to the greased 9"x9" baking dish. Use a rubber spatula to evenly spread out the mixture.
5. Make the topping by combining in a small bowl, the panko crumb, parmesan, and olive oil.
6. Sprinkle the panko topping into the baking dish evenly on top of the asparagus-rice mixture. Bake for 20–25 minutes, until hot throughout and golden on top. Let the casserole sit for about 5 minutes before serving so the sauce sets slightly.
Storing the casserole
Let the baked Asparagus Lemon Rice Casserole cool completely before transferring it to an airtight container to preserve its texture and flavor. Store the casserole in the refrigerator for up to 4 days, keeping it well covered to prevent it from drying out. Reheat individual portions in the microwave or warm larger portions in the oven at 350°F (175°C) until heated through. Freeze leftovers in a freezer-safe container for up to 2 months, then thaw overnight in the refrigerator before reheating for best results.
