What is your go-to pot luck dish?

That would work if she was assigned a dessert~~

Hmm...what about a chicken/broccoli/rice casserole?? I am no good at a recipe as I usually just wing it. I use creme of broccoli soup and milk etc. I bet you could find a good one on Pinterest.  

ooops, there I go, skimming again. I didn't see you were assigned an entrée.

if I had to bring an item that can be warmed in a crockpot, I would do some kind of bbq pulled pork. that keeps well in the fridge, heats well and can sit in a crock pot without getting all dried out.

Wait!  Pasta is a whole different category from casserole?  Crazy!  How about unstuffed pepper casserole?  I'll post a recipe in a minute. 

This is another of my faves...

Total Time: 55 mins

1 medium onion, chopped
I can (15 oz) diced tomatoes, drained
Minced garlic
Garlic salt, onion powder, Italian seasoning to taste
2 medium bell peppers, seeded and finely chopped
1 1/2 cups tomato sauce (could add an extra 1/2 c)
1 cup shredded cheddar cheese

Brown meat with pepper and onion and garlic. Drain well. Season with garlic salt, onion powder, Italian seasoning. Stir in diced tomatoes and sauce. Pour over rice.

Lasagna?
Baked Ziti?
Funeral Potatoes?

How about this really simple crockpot orange chicken? You could partialy pre-cook it Thursday and finish it up Sunday morning:

Orange Chicken

Note:

I usually add a little sesame oil and ginger when I make it.

My family calls it potato casserole - I think here on this board it is roughly the same thing as/very similar to funeral potatoes.  If you need a recipe, just holler!!  It's super easy and always disappears!

I usually bring a fancy green salad or a spinach salad.

In that category I would bring stuffed spinach shells or grilled salmon.

I always bring small meatballs with garlic mayo dip. They are always a big hit, never leftovers
(but that's more of a tapas, not a casserole or complete dish)

Funeral potatoes, salad & dressing and either corn on the cob or skillet corn. Those have been my go-tos for potlucks all summer!

If I'm pressed for time, then my quick, go to is from Smart and Final:

Pick up a bag of frozen meatballs
a large bottle of sweet and sour sauce

Dump them both in a crock pot, by the time lunch is served the meatballs are soft and saucey and everyone goes nuts over them! They are always a favorite.

I feel like such a cheat but wow, so EASY!

I agree with the meatballs. I'd do the grape jelly meatballs.

Maybe slow-cooker meat loaf?  That always goes over big at our pot luck functions.
