Why We Love This Potsticker Casserole
This has quickly become one of those meals we keep coming back to. It may not show up on the calendar every week, but it definitely makes a regular appearance in my meal plans.
- It is an easy weeknight dinner with almost no prep
- It is completely dairy-free, making it perfect for lactose intolerance
- It feels fun and a little different than your usual dinner rotation
- It works for hosting, family dinners, or solo meals
- You can eat it on its own or pair it with simple vegetables
And if you love potstickers like I do, turning them into the main dish instead of just a side is a gamechanger.
I also think potstickers just have a special spot in my heart. I recently spent a morning sitting with a friend, and at about 11:30, she asked if I just wanted to stay for lunch. She knew I loved potstickers because we’d talked about her magic sauce before. So she pulled together what she had on hand and made us a Potsticker bowl for lunch. It wasn’t this dish, but every time I eat this, I think of her and the way she made me feel sitting at her table with an impromptu lunch.
Isn’t that just the way it should be? An empty seat at a table, an invitation to linger, and using what you have to hold tight to friendship!
