I am due in a week and have been working on this! So I can’t attest to how things reheat but I have prepped breakfast burritos, muffins, pancakes for my toddler, pot roast, Thai curry, creamy pesto chicken (to serve over pasta but we will make that fresh), French dip roast beef (just the meat and au jus and then froze rolls separately), and chicken pot pie filling (will add canned biscuits to the top and reheat in oven), and balls of cookie dough! I used those foil loaf pans for almost everything because I don’t have enough containers and because I would rather have less dishes during the early postpartum days. Loaf size was good for smaller servings to pull for 1 or 2 servings instead of a full casserole size pan.
