Dear Wirecutter,
I’m a fan of reusing plastic takeout containers for leftovers and sending food home with friends after dinner. My husband thinks it’s unnecessary, but I see it as practical. What’s your take?

Dear M.C.,
Ah, the joy of post-holiday meals! For me, Thanksgiving leftovers mean one thing: a carb-loaded masterpiece of turkey, gravy, stuffing, mashed potatoes, and cranberry sauce piled into a toasted roll. My sister’s annual hosting ensures I get my fix—all thanks to her generosity with leftovers.
Your hospitality is commendable, and sending guests home with extra food is a thoughtful gesture. But here’s where it gets controversial: while plastic takeout containers are fine for short-term transport, we don’t recommend reusing them long-term, especially for reheating. And this is the part most people miss—the reasons behind it are more complex than you might think.
Why Reusing Takeout Containers Isn’t Ideal
Let’s start with the obvious: takeout containers lack standardized manufacturing. That mismatched pile of lids and bottoms? It’s not just annoying—it’s a symptom of a larger issue. But the real concern lies in the plastic itself.
While the initial panic over harmful chemicals in black plastic kitchenware has subsided, the broader issue of plastic and microplastics remains. Studies are still unraveling the health impacts of microplastic exposure, but one thing is clear: if you’re aiming to reduce your exposure to potentially harmful chemicals, long-term food storage and reheating in plastic aren’t ideal.
As Wirecutter’s sustainability editor Katie Okamoto puts it, “Reusing plastic to cut down on waste is admirable, but takeout containers aren’t designed for repeat use. They’re more likely to shed microplastics and chemicals, especially when heated.”
So, what’s the solution? For short-term use, go ahead and pack those leftovers. But encourage your friends to transfer the food into safer containers within a few days. Leftovers should be consumed within three to four days or frozen for longer storage. If you’re feeling guilty about piling containers, repurpose them for non-food items like craft supplies, or check if your local recycling accepts them.
Better Alternatives for Long-Term Food Storage
When it comes to storing food safely, glass containers are your best bet. Our top recommendations include the Pyrex Freshlock 10-piece Glass Storage Set (available on Amazon) and the Snapware Total Solution Pyrex Glass 10-piece Set (found on Walmart). Both feature tempered-glass containers with airtight, locking lids.
If you prefer lightweight plastic, consider the Snapware Total Solution 20-Piece Plastic Set (available at Target), but avoid microwaving it. For keeping leftovers fresh, reusable silicone bags like the Stasher Reusable Silicone Bag (on Amazon) are a great addition.
Pro Tip: Keep your fridge organized by labeling leftovers with FrogTape Multi-Surface Painter’s Tape (on Amazon) and a Sharpie. Trust me—it’s a game-changer for avoiding mysterious fridge discoveries.
Encourage BYOC (Bring Your Own Container)
Asking guests to bring their own containers might feel awkward, but it’s a simple way to reduce waste. As a host, you can casually suggest, “We’d love to send you home with extra lasagna—just bring a container, and I’ll pack it up!”
I’ve even started BYOC-ing at restaurants, much to my husband’s embarrassment. It takes seconds to transfer leftovers into a clean container from my purse. While restaurants may not accept your containers for regular takeout, no one’s stopped me from packing my own doggy bag.
Repurpose Glass and Tins Instead
If you’re a jar collector like me, it’s time to put those glass treasures to use. Cleaned glass jars with metal lids are perfect for storing leftovers. Just be cautious with secondhand containers—older serveware might contain lead, which is a health hazard. Thrifted clear glass pie plates or food-safe cookie tins (avoid corroded ones) are excellent alternatives. Recently, a friend sent me home with cake in a Trader Joe’s peppermint bark tin lined with parchment—it was both stylish and practical.
Final Thoughts
Reusing takeout containers for non-food purposes or short-term transport is fine, but for long-term storage and reheating, opt for safer alternatives. But here’s the real question: Are we willing to trade convenience for potential health risks? Let us know your thoughts in the comments—do you reuse plastic takeout containers, or have you switched to glass and other alternatives?
