Can you reheat lentil shepherd’s pie?
Absolutely! You can reheat leftover lentil shepherd’s pie in the oven or microwave much like you would reheat a meat shepherd’s pie.
To reheat in the oven, preheat the oven to 350°F, place your shepherd’s pie in an oven-proof casserole dish covered with foil, and heat a single portion for 10 minutes or an entire pie for 30-40 minutes until warmed through. To reheat an entire shepherd’s pie from frozen, follow the same instructions but extend the cooking time to 60-90 minutes to ensure the entire shepherd’s pie is completely warmed through.
To reheat in the microwave, place your shepherd’s pie in a microwave-safe dish and warm single portions on high for 2-3 minutes, with additional 30-second increments as needed, until warmed through.
Swaps and Alternatives
Short on time? Swap the dry lentils for canned lentils. Use three 15-ounce cans of lentils instead of 1 cup of dry lentils.
Want to make it low-carb? Top the shepherd’s pie with mashed cauliflower instead of mashed potatoes.
